  • Classification and Comparison of Malignancy Detection of Cervical Cells Based on Nucleus and Textural Features in Microscopic Images of Uterine Cervix   Order a copy of this article
    by Shanthi P.B, Shivani Modi, Hareesha K.S, Sampath Kumar 
    Abstract: Cervical cancer is one of the major cause of death among women worldwide. Pap smear is the cytology based screening test which is used to detect abnormal cervical cells including pre-cancerous lesions. Accurate classification of Pap smear images is one of the challenging task in medical image processing and its performance can be enhanced by extracting and selecting the well-defined features and classifiers. The irregular chromatin structure is one of the prominent diagnostic feature of abnormal cells. Classification is performed based on the extracted textural features and the benchmark Herlev dataset features. RBF (Radial Basis Function), Polynomial and Sigmoid SVM kernels are used for classification and comparison is performed with the features in benchmark database. Precision, Recall and Accuracy were calculated for all the combinations of the features. The classifier gives promising results when benchmark features are combined with textural features and also benchmark nucleus features with textural features. An effective integration of features for cervical cell classification had given good results for fast abnormal cell detection and primary Pap smear cell image classification.

    by A. Udaya Kumar, R. Raghavi, R. Reshma, S.P. Angeline Kirubha 
    Abstract: Fractional flow reserve (FFR invasive) is measured by measuring pressure differences across a coronary artery stenosis by coronary catheterisation technique. This is a gold standard method of determining the extent of stenosis. This method has some potential complications such as coronary vessel dissection, embolism, and renal failure. This paper presents a method for an assessment of FFR noninvasively, with coronary CT angiography imaging and fluid dynamics modelling. FFR is calculated as the ratio between pressure distal to stenosis and pressure proximal to stenosis of the coronary artery region segmented from CT Angiography image using MIMICS software. ANSYS software is used to determine the FFR (0.73

    by Saravana Kumar Ramachandran, Manikandan Parasuraman 
    Abstract: In this paper, we indented to propose a consolidated feature selection and ensemble-based classification strategy to diminish the medical big data. Here, the proposed system will be the joint execution of both the Ant Lion Optimizer (ALO) and ensemble classifier. So as to limit the impact of an imbalanced healthcare dataset, ALO is used for the optimal feature selection process. The optimized feature sets are classified by utilizing the ensemble classification technique. The ensemble classification method uses the diversity of individual classification models to create better classification results. In this paper, the proposed ensemble classification algorithm used the Support Vector Machine (SVM), and Recurrent Neural Network (RNN) classifier and the results of every classifier were consolidated by the majority voting technique. It was watched that the proposed ensemble technique got promising classification accuracy contrasted and other ensemble strategies. This ensemble system can administer datasets, as quick as required giving the imperative help to viably perceive the underrepresented class. The proposed approach will diminish the big medical data precisely and productively. The simulation result shows that the proposed method has better classification when compared with the single classifiers such as Random Forest (RF), SVM and Na

  • Analysis and monitoring of a sensor-pill using DQPSK, with Advanced Virtual Instrumentation.   Order a copy of this article
    by Ajay Sharma, Hanuman Prasad Shukla 
    Abstract: Recording vital parameters of the internal parts of our human body is complex and challenging, so to get the exact or the accurate value we do the approximation of the data. Now to bridge this gap of accurate and approximate, technology has now taken a huge jump, and have come forward with something known as swallowable sensor pill. Although, we can not imagine of swallowing anything other than food items but still it is working. The electronic pill (e-pill) discussed in this model already exists, and works on a complete wireless independent system, on a two-way synchronous DQPSK technique using low carrier frequency of 150300 kHz suited for human body. This small system is incorporated in a small swallow able pill, powered by a special 3v button cell. The received body vital signals, i.e., temperature, SpO2 level, pH value, etc., will be live monitored and analysed using the biomedical toolkit of LabVIEW 8.5, in addition to it a comparative chart of more than one patient can be made for comparative analysis.

  • Knee pathology diagnosis based on muscle activation intervals detection and the relationship between knee flexion and surface EMG   Order a copy of this article
    by Ahlem Benazzouz, Zine Eddine Hadj Slimane 
    Abstract: Muscle activation interval is an important clinical indicator for muscular disorders diagnosis. In this study, the S transform technique was proposed to detect the muscle activation onset and offset timing during gait and determine the relationship between surface electromyographic signals and knee pathology. The results obtained show that the proposed method achieved the shortest average latency (t_onset=0.015s, t_offset=0.014s) compared to the recent methods: SampEn, TKEO, and Integrated Profile. Moreover, the statistical analysis of activation intervals diversity and correlation between sEMG and knee flexion signals provide that for abnormal cases, the linear relationship is very weak and the activation intervals become more diverse.

  • Bone metastatic tumour minimisation due to thermal cementoplasty effect, clinical and computational methodologies   Order a copy of this article
    by V.C.C. Oliveira, Elza M. M. Fonseca, J. Belinha, C.C. Rua, P.A.G. Piloto, R.M. Natal Jorge 
    Abstract: The main objective of this work is to study the thermal effect induced by the bone cement polymerisation, in the metastatic tumour minimisation and to understand the role of such procedure in bone tumour necrosis. Different numerical simulations were produced for different cement sizes introduced in a cortical and spongy bone tumour, with or without an intramedullary nail in titanium. The numerical models were built according to average dimensions of patients obtained from digital conventional radiographs. The finite element results allow to conclude about the high temperature spread effect in bone material. In conclusion, values greater than 45 C were obtained in models without the intramedullary nail system. High quantities of cement produce thermal necrosis in bone with more pronounced effect in depth. The temperature located on the intramedullary nail induces heat transfer along the axial length of the bone, due to the metallic nail, justified by its high thermal conductivity.

  • Real-time estimation of hospital discharge using fuzzy radial basis function network and electronic health record data   Order a copy of this article
    by Ahmed Belderrar, Abdeldjebar Hazzab 
    Abstract: Hospital resources are scarce and should be properly distributed and justified. Information about how long patients stays in critical intensive care units can provide significant benefits to hospital management resources and optimal admission planning. In this paper, we propose an approach for estimating intensive care unit length of stay using fuzzy radial basis function neural network model. The predictive performance of the model is compared to others using data collected over 13,587 admissions and 54 predictive factors from five critical units with discharges between 2001 and 2012. The proposed model compared to others demonstrated higher accuracy and better estimations. The three most influential factors in predicting length of stay at the early stage of pre-admission were demographic characteristics, admission type, and the first location within the hospital prior to critical unit admission. We have found about 63% of patients with multiple chronic conditions, stayed significantly longer in hospital. Enabling the proposed prediction model in clinical decision support system may serve as reference tools for communicating with patients and hospital managers.

  • A NOVEL METHOD FOR AUTOMATIC IDENTIFICATION OF FOVEA LOCATION AND ITS CENTER IN COLOR RETINAL FUNDUS IMAGES   Order a copy of this article
    by Bharati M. Reshmi, Rajesh I S, Bharathi Malakreddy A 
    Abstract: The identification of fovea region plays a significant role in the detection of Diabetic Maculopathy. The presence of exudates within 500micrometer from fovea center requires laser treatment as it is a sign of sight-threatening. An ophthalmologist can decide over the nature of the treatment depending upon the position of the exudates from the fovea. Hence it is very important to identify fovea and its center with high accuracy. In this work, we have proposed a novel algorithm for identification of fovea location and its center in color retinal fundus images. The novelty of this work aims at an approach where fovea location and its center identification are done excluding blood vessels and OD. Initially, the grid is drawn over the retinal image, then the designed algorithm searches for Region of Interest (ROI) for the candidate fovea region by considering the four coordinate points. Finally, by using dark intensity property of fovea and morphological operations, fovea location and its center is identified. The proposed method is simple, robust and it is tested on a publicly available MESSIDOR database and an accuracy of 97.37% is achieved.

  • Optic Disc and Optic Cup Segmentation in Retinal Images   Order a copy of this article
    by Thamer Al Sariera, Lalitha Rangarajan 
    Abstract: Automated segmentation of the optic disc (OD) and optic cup (OC) is important for retinal image analysis and retinal diabetic retinopathy systems. For OD segmentation, this paper presents a method done in three steps that combines variance and brightness features of the OD to localize leading to increased accuracy in detecting OD rather than using just one feature. As a first step, the image is divided into non-over lapping windows. Then the brightest window with maximum variance in intensity is selected. Subsequently the Circular Hough Transform (CHT) is applied to get the OD segmentation. OC segmentation,is done in two steps:(i) blood vessels inside the OD are eliminated and (ii) restricted region growing performed to get the OC segmentation.The efficacy of the proposed method is demonstrated using the standard benchmark DRIVE and DIARETDB1 databases and by comparing the results of proposed method and some methods in silico.

  • A Low-complexity Volumetric Model with Dynamic Inter-connections to Represent Human Liver in Surgical Simulators   Order a copy of this article
    by Sepide Farhang, Amir Hossein Foruzan 
    Abstract: We propose a method for visualization of the human liver to represent nonlinear behavior of the tissue and to preserve the objects volume. Our multi-scale model uses dynamic interconnections to keep the size of the gland. We introduce two new parameters to control the influence of an external force on the non-linear material of the liver. Another novelty in the proposed method is to design a multi-dimension data structure which makes it possible to run our code on conventional CPUs and in real-time. We evaluated the proposed algorithm both quantitatively and qualitatively by synthetic and clinical data. Our model preserved 98.4% and 94.1% of a typical volume in small and large deformation, respectively. The run-time of our model was 0.115 second. Our model preserves the volume of a liver during both small and large deformations, and our results are comparable with recent methods.

  • MR-Brain Image Classification System based on SWT-LBP and Ensemble of SVMs   Order a copy of this article
    by Mohammed Khalil, Habib Ayad, Abdellah Adib 
    Abstract: In this paper, we present an efficient MR (Magnetic Resonance) image classification system. At the first stage, the brain image is decomposed into several subbands using Stationary Wavelet Transform (SWT). Then, Local Binary Patterns (LBP) with reduced histograms are computed for each subband to form several primary feature vectors. Principal Components Analysis (PCA) followed by Linear Discriminant Analysis (LDA) are then applied to each primary feature vector in order to transform them into new lower-dimension feature vectors. The third stage consists of using an ensemble of Support Vector Machines (SVMs) in order to build voters and make the final decision on the requested image. The designed system is evaluated on 255 brain images with Five-fold cross-validation. Experimental results show that the proposed system achieves a classification rate of 99.78% which outperforms the existing brain classification approaches.

  • Electro-pneumatic system for intussusception reduction in children and its application in the pediatric surgery   Order a copy of this article
    by Mohamed Ras Lain, Chouaib Daoudi, Mohamed Souilah, Abdelhafid Chaabi, Hichem Choutri 
    Abstract: Intussusception is an important cause of acute abdomen pain in infants and children that often occurs between 3 and 12 months of age. The early diagnosis of this disease is vital factor to avoid recourse to surgery that can poses a real danger to the infant. Recently, pneumatic reduction (Air / Gas) has emerged as a safe and promising method in the treatment of intussusception. The work presented in this article focuses mainly on the implementation of embedded instrumentation based on pressure sensor to improve the manual pneumatic system, which is currently used by the doctors. Initially, a sensor of the Motorola family (MPX 7050) is used for the acquisition of intestinal pressure. The signal conditioner is based around a specialized amplifier and the processing unit is built around Microchip PIC microcontroller. A keyboard and LCD display were used to introduce and visualize the evolution of intestinal pressure, respectively. The experimental results show the feasibility of the designed prototype in the treatment of intussusceptions.

  • Ex vivo experimental and numerical study of stresses distribution in human cadaveric tibiae   Order a copy of this article
    by Maria G. Fernandes, Elza M.M. Fonseca, Renato N. Jorge, Maria C. Manzanares-Céspedes 
    Abstract: The mechanical behaviour of human bone tissue subject to drilling has been recently reviewed due to its increased clinical interest. However, no published data exist regarding stress analysis during the drilling. In this study, an elasto-plastic dynamic FE model of bone drilling was developed using the human cadaveric tibia obtained with a handheld 3D scanner. The FE model was validated with experimental tests and different drilling conditions were simulated in order to study the stresses distribution during the drilling process. The developed FE model was in good agreement when compared with experimental tests. Results suggest that the use of lower drill speed and higher feed-rate lead to a decrease in the stress level of the treated tibial bone. The developed FE model can be used for future studies and cover not only the mechanical behaviour of human tibiae but also the thermal aspects.

    by Jalal AlAlwan 
    Abstract: Despite the abundance of researches relating children and asthma, the racial/ethnic influence on asthma threat have not been fully explained. The aim was to conduct a consistent and new study on a large-scale nationally representative data, including a minority group that has been usually eliminated form racial/ethnic literature. The 2011-2012 National Survey of Children Health (NSCH) dataset was utilized. Asthma was more prevalent among African American children (22.9%) more than white American children 13.1% (p=<.0001). Analysis of the multivariate model revealed a greater risk of asthma for the black African American children comparatively to white American children (adjusted OR" 0.522 95% CI 0.459-0.595). Our findings indicated that childhood asthma was associated with racial/ethnic status, especially with children with low income level.

    by Asma Belaidi, Mohammed El Amine Abderrahim 
    Abstract: Accessibility to information resources in health systems is a very important aspect. This article is about the protection of medical data and focused primarily on access control in health information systems. It is therefore a question of proposing a rigorous modelling allowing to take care of all the aspects related to the secure management of electronic health record. We proposed in the first time a model to the management of the electronic health record in the context of an Algerian health organization. Based on this modeling and by using Or-BAC model, in a second time, we proposed a model of the access control to this electronic health record. The validation of this model using the MotOrBAC tool allowed us a safe passage to an implementable specification. As a result, we develop a set of simple and effective tools to support this aspect.

  • R-peak detection for improved analysis in health informatics   Order a copy of this article
    by VARUN GUPTA 
    Abstract: Improvement in R-peak detection of Electrocardiogram (ECG) signal is still not saturated even requires better preprocessing, feature extraction and detection stage. Proper detection of heart diseases using the proposed technique only leads to increase its applications in medical engineering for health informatics. R-peak detection is very important for detecting heart diseases, but the involvement of various types of noises makes its detection too much complex. In this work, discrete wavelet transform (DWT) is used as preprocessing tool and Hilbert transform (HT) is used as a feature extraction tool for spectral estimation (in the form of trajectory pattern). Finally, principal component analysis (PCA) is adopted for reducing feature vectors. Detection of R-peaks is accomplished on the basis of variance obtained by first principal component (PC1). For validating this research work MIT/BIH (Massachusetts Institute of Technology/Beth Israel Hospital) Arrhythmia database has been used. The proposed technique was evaluated in MATLAB environment R2015a. The detection sensitivity (SE), positive predictivity (PP), F-score (F-s) and mean squared error (MSE) are estimated for evaluating the performance of the proposed technique. The proposed technique has resulted into SE of 99.88%, PP of 99.88%, F-s of 99.88%, SNR of 7.60dB and MSE of 0.8131%.

    Abstract: Musculoskeletal pain is a heterogeneous condition with multiple risk factors, primary sources that can affect treatment and rehabilitation outcome. In this paper, we developed a prediction model for therapeutic subgrouping of musculoskeletal pain using ANN. A dataset of 27 patients with neck/shoulder pain. Patients received a single injection(0.2 ml) of 0.5% lidocaine at the trigger points.ANN model were used for predicting treatment outcome based on influential pre-treatment variables as inputs. Leave One Out Cross Validation (LOOCV) method was used for validation. The strength of each predicting variable was tested using Multilayer Feed Forward Neural Network with Back Propagation(MFFNN) and LOOCV. Then, the MFFNN prediction model was developed and designed based on the selected variables. Post-treatment endpoint follow-up(4th week VAS) was selected as a good indicator of treatment outcome. Serum vitamin D and ferritin were relatively better predictors of treatment response in the current patient group. ANN obtained 85% prediction accuracy.

  • An enhanced, efficient, affordable wearable elderly monitoring system with fall detection and indoor localization.   Order a copy of this article
    by Ch Vineeth, Anudeep Juluru, Gudimetla Kowshik, Shriram K Vasudevan 
    Abstract: According to the statistics of NCOA (National Council on Aging) these days rate of death in the old aged people has reached a critical state that, for every 11 seconds an older adult is being treated for a fall and for every 19 minutes a death is reported. Most of the people leave their parents alone in the home and go for their respective jobs. In case of any fall or mishap happens to the elderly who are back at home, they are left unnoticed which may be fatal or lead to incurable disease like hip injuries, hemorrhage, tachyarrhythmia which is approximate to a cardiac arrest or even lead to death. In order to reduce these types of risks faced by elderly people, we designed an affordable IoT wearable product that can monitor their movement, the health of old people which can detect their fall immediately. Falls inside the bathroom may be fatal even for young, healthy people. Most of the elderly persons tend to remove their wearables before entering the bathroom and one cant force them either. In order to detect falls even without wearable band, we designed a smart bathroom which is capable of detecting falls and alerts when a fall occurs. These type of bathrooms can be installed in houses, hotels in order to ensure their customer safety. Deaths due to unnoticed falls inside the bathroom can be prevented by installing our system, which will alert the respective authorities immediately when a fall is detected.

  • A new design of real-Time monitoring and spectral analysis of EEG and ECG Signals for epileptic seizure detection   Order a copy of this article
    by Boumedyen BELAID, Zine-Eddine HADJ SLIMANE 
    Abstract: The evolution of telecommunications technology has made significant contributions and advances in medical technology. Most of the time, monitoring and evaluation require the use of more than two signals simultaneously recorded. Simultaneous monitoring of the electrocardiogram (ECG) and the electroencephalogram (EEG) is very useful to have information about general state of health of the patient. In this paper, a novel mono-channel wireless ECG&EEG system for epileptic seizure detection is presented. The system employs analog circuits to acquisition, processing and spectral analysis of ECG and EEG signals simultaneously. Arduino Platform is used to digitize and spectral analysis of signals. A 128x64 Graphic LCD Display module and a Bluetooth module are also used for plotting and transmission of signals. We also propose the magnitude squared coherence (MSC) as an important parameter to calculate in frequency domain the relationship between ECG and EEG signals and use it as a relevant discriminator in seizures and the epilepsies classification.

  • Detection of Dichromacy and Achromatopsia Using LabVIEW   Order a copy of this article
    by Kandaswamy A, MALAR ELANGEERAN, Ahilaa T.D., Indrani R. 
    Abstract: The eyes are undoubtedly the most sensitive and delicate organ we possess, and perhaps the most amazing. We rely on our eyesight more than any other sense. Such a human eye faces numerous problems, one such problem with maximum difficulty is Dichromacy and Achromatopsia i.e. complete color blindness. Color blindness is a condition in which people may have mild to severe difficulty in identifying colors. They may not be able to recognize various shades of colors and, in some cases, cannot recognize colors at all. The retinal cone cells are responsible for color white or gray. Total color blindness is called Achromatopsia. This software proposes vision. The three basic types of color blindness are Red, Green and Blue color blindness-generally called as Dichromacy.

  • Performance evaluation of a computational model for brain shift calculation   Order a copy of this article
    by Karin Correa, Natividad Bermejo, Oscar Andrés Vivas, José Maria Sabater 
    Abstract: This article shows a solution for the computation of deformable tissues displacements in the brain shift problem in neurosurgery. In this type of surgery, the brain moves and deforms, changing the pre-surgical reference the surgeon had before the intervention. Among the causes of brain shift are the effect of gravity, loss of cerebrospinal fluid as a consequence of the resection practiced, the effect of the drugs supplied, among others. This document refers to the physical model of this displacement to later simulate them in multiphysics software. A phantom test was constructed by means of hydrogels, imitating the porcine brain tissue, which is subjected to compression along the z axis. The results show that the simulation proposed reproduces the behavior of the real phantom with a high level of accuracy. The application developed may serve in the future to reproduce the total behavior of the brain and thus obtain a better calculation of the brain shift.

  • Brainwave entrainment through external sensory stimulus: a therapy for insomnia   Order a copy of this article
    by Karuppathal Easwaran, Kalpana R, Srinivasan A.V 
    Abstract: In this work audio, visual and haptic stimuli are used to improve overall sleep quality for insomnia subjects. Two audio signals at two different frequencies were given to left and right ears. This results in binaural beat signal in delta band. Visual input is also given to two eyes through eye-mask to block the entry of external light. Automated system is developed to give pressure at HT-7 with time and pressure control. This therapy is self-administered by the TEST group (who are diagnosed for insomnia) for a brief period on regular pace. Brain signals are acquired before and after therapy to understand the influence of AVE. Subjects who are not into insomnia (CONTROLs) are also studied for sleep pattern to make baseline comparison. By analysing power spectrum of these signals, results demonstrate that average delta signal power increases by 10% becoming at par with CONTROLs. The test responses are also statistically analysed using Cohens d value. The obtained results demonstrate impact of this therapy as significant changes in quality of sleep. Also, insomnia subjects who are not into oral medicine shows better response, in the sense their rhythmic changes became almost similar to that of CONTROLs with marked increase in REM state duration, reaching 20% of full sleep time, a normally recommended value. Thus this being a drug free therapy could be useful to treat insomnia soon after diagnosis and hence could prove to be more useful to the society.

  • Classification of Vertebral Fractures in CT Lumbar Vertebrae   Order a copy of this article
    by Adela Arpitha, Lalitha Rangarajan 
    Abstract: The existence of a vertebral fracture (VF) in particular compression fracture indicates osteoporosis and is a sole powerful predictor for the advancement of another osteoporotic fracture. With the number of imaging scans consistently expanding, identifying different cases and grades of osteoporotic fractures are missed by the over-burdened radiologist. The objective of this paper is to automatically segment and classify vertebral body fractures. Individual vertebral body is segmented by feeding preprocessed images to hybrid FCK-means algorithm. The shape features from the segmented output and texture features from the original input image are extracted and fed to an artificial neural network (ANN) which performs multiclass classification of vertebral body compression fractures and its associated fracture grades. Our method resulted in an overall classification accuracy of 93.14% based on Genants scoring for VF. The result concludes that with this approach, the clinicians task in diagnosing fractures is made simpler and also aids in suggesting for further treatment.

  • Power Analysis of EEG Bands for Diagnosis of Alzheimer Disease   Order a copy of this article
    by Sachin Elgandelwar, Vinayak Bairagi 
    Abstract: Identifying the early and fundamental stage of Alzheimer Disease (AD) called as Mild Cognitive Impairment (MCI) is needed for better medical care. The basic goal of the current research is to evaluate the electroencephalography (EEG) for the diagnosis of AD and to separate the AD from the normal healthy subjects. The EEG signals has diverse frequency bands which reflects mental functions and memory performance of the humans. The EEG is non-invasive and measurable brain signal, which can be used for detecting the memory functions in the case of AD where there is significant slowdown of brain cognitive functions. The present study is based on analysis of power and frequency of EEG signals, which reflects the connection between specific EEG frequency bands and their relative power (RP). It is observed that relative power of few EEG signal bands is closely linked with the AD staging. Slowing of EEG signals is the main feature found in AD subjects. Such slowing down of EEG is increasing the relative power of delta and theta bands, along with the decreased in the power of alpha and beta bands of EEG. This paper shows the relative power analysis of each band in EEG signals to detect the severity of AD

    by V.C.C. Oliveira, Elza M. M. Fonseca, C.C. Rua, J. Belinha, P.A.G. Piloto, R.M. Natal Jorge 
    Abstract: The main objective is to study the thermal effect induced by different bone cements associated to intramedullary nails in titanium and carbon, in bone metastases treatment. The thermal necrosis effect of each cement polymerisation was verified to understand the role of such procedures. Numerical models with nailing systems, introduced in a cortical and spongy bone metastasis, were developed aiming to predict the temperature produced by different types and amount of cement polymerisation. The results showed that the polymerisation heat release in all models with a cement mantle filling in around the intramedullary nail and the necrosis largest area was predicted with CMW3. It was verified that CF/PEEK nail and high viscosity Palacos R reduce the heat transfer and the necrosis affected area. This effect could be an advantage for treatment, which aims to keep long-term stability and local metastatic disease control for functional improvement and pain relief.

  • Implementation of non-contact bed embedded Ballistocardiogram (BCG) signal measurement and valvular disease detection from this BCG signal   Order a copy of this article
    by M.A. HAFIZ, Abdullah Mahammed Hashem, Ainul Anam Shahjamal Khan, Md. Hossainur Rashid, Md. Azad Kabir Faruqui 
    Abstract: Electrocardiogram (ECG) is the most common practice to diagnose cardiac abnormalities. In a traditional system, some ECG leads are connected to the patients chest to detect the electrical performance of the heart. For long term observation, this method creates discomfort for the patient. Non-contact measurement of cardiac performance can alleviate this discomfort. As BCG and valvular diseases both are mechanical phenomena, we conjectured that valvular disease could be diagnosed from non-contact BCG measurement. In this paper, we proposed a non-contact way to determine the valvular diseases of the heart which is favorable for long term observation of the patient. The ballistic force of heart was sensed using a series-connected array of piezoelectric elements embedded in the bed. We collected data from two local famous hospitals. We classified the data using Artificial Neural Network (ANN) and Support Vector Machine (SVM). We collected data from normal persons and persons affected by Mitral and Pulmonary Valve Stenosis. After analyzing the data, we nearly predicted the conditions of the persons. We compared the result using overall accuracy, misclassification rate and fitness. We collected 80 data of normal and valvular disease affected patients. We got the highest test accuracy of 79.12% for SVM technique for decomposition level 1. As this technique is completely new and advantageous, it can lead to a new research area of valvular disease detection.

  • Controlled magnetic field influence for reperfusion in aortic blood flow using a unified solution approach   Order a copy of this article
    by Ebenezer Ige 
    Abstract: The haemoglobin content of the blood contains iron constituent which makes body fluid a transport medium suitable for magnetic field-based therapeutic interventions and diagnostic applications. However, in cases of aortic dissection (AD), disturbances occasioned by the changes in cross-section affects the distribution of hematocrit (HTC) in the blood flow suggesting ruptured AD and this could result in ischemic insult and could be determined by the magnitude and direction of interruption of blood flow leading to reperfusion. This condition may affect considerably the allosteric-property of blood flow because of oxygenation sensitivity (OS) impairs imaging procedure in magnetic field-based interventions. In this study, we utilized the Einstein viscosity model to formulate a unified solution coupling wall deformation of AD effect, blood flow and magnetic field in a unified equation. The simulation was undertaken for varying HTC from 60% to 80 % for selected controlled values of magnetic flux; we observed pressure distribution in the region of AD showed rapidly increasing momentum and haemodynamic instability. It could be inferred that the contribution of the local magnetic field is directed to the relaxation of the muscles in the region of aneurysm while maintaining the blood flow at uniform distribution. The appreciation of scaled controlled magnetic effects demonstrated in this work could be applied to the management of critical cardiovascular issues such as necrosis and sepsis in a magnetic field environment.

    by Nur Fatien Najwa Mohamad Narji, Mohd Ridzuan Ahmad 
    Abstract: Cancer is a leading cause of death that gives a negative impact on all ages and genders worldwide. There are a variety of methods to detect this disease such as CT scanning and Mammography. Even though the current methods have many advantages, however, most of the methods share similar disadvantages such as the detection result takes a long period. Sometimes, the results are not accurate, which can cause overdiagnosis or vice versa. Dielectrophoresis (DEP) is a label-free method, which can be used to obtain the parameters of cell electrical properties such as capacitance, conductivity, and permittivity of the cancer cells. rnIn this study, a device was designed with a pair of electrodes and the main channel with two inlets and two outlets. COMSOL software was adopted to study the flow of the particles in the channel. After that, the COMSOL software was used to run the simulation of the cell properties. The results presented two findings, i.e. the optimal design and dimension of the microfluidic device and cell sorting application. The simulations reveal that the particles were successfully captured by the electrodes and sorted within a specific time. The probability of cell capture and the ability of the electrodes to sort out the cells is about 80%. As for the potential application, DEP can be used as a non- invasive technique to separate the normal cells and cancerous cells, which can lead to early detection as it gives a real-time notification.rn

  • EFFICIENT TUMOUR DETECTION FROM BRAIN MR IMAGE WITH MORPHOLOGICAL PROCESSING AND CLASSIFICATION USING UNIFIED ALGORITHM   Order a copy of this article
    by G. Sethuram Rao, D. Vydeki 
    Abstract: Brain diseases caused due to malignant are the biggest concern among all the age groups. Studies show that almost 80% of death cases are reported due to presence of malignant tumour. Hence diagnosing brain tumour at an early stage would increase the survival rate. Magnetic resonance imaging (MRI) plays a major role in diagnosing tumours in human brain. However, it is considered to be a time consuming and tedious process which could lead to deviation in the opinion of radiologists. This has led to the development of computer-based automatic extraction of tumour cells from the images obtained by MRI. This paper proposes an efficient tumour detection mechanism from MR images using morphological processing and unified algorithm. A neural network that uses bounding boxes and associated class probabilities detects the packets of tumour that exist in a full MR image. Simulated results of the proposed technique on the BRATS 2016 dataset show that a detection accuracy of 95.97% is achieved, while reducing the likelihood of false positives. This approach is compared with other detection methods such as DPM and R-CNN and the analysis proves that our method proposed outclasses the other detection methods.

    by Sangita Bharkad 
    Abstract: Revealing and extraction of Optic Disc (OD) in fundus images is the most important step in automatic screening system of diabetic retinopathy. The algorithm presented in this paper is focused on revealing and extraction of Optic Disc (OD) in fundus images. This algorithm adopts frequency domain approach to focus the OD and mathematical morphology for extraction of the OD. Large pathological signs, bright lesions limit the OD segmentation performance as brightness of both OD and bright lesions is similar. Bright lesions are extracted before localization of the OD using DFT and morphological dilation is used for segmentation of the OD. This method was assessed on standard databases namely: DRIVE, DIARETDB1 and DIARETDB0. This algorithm acceptably recognizes the OD in 255 out of 259 retinal images (98.45%) in 0.75 seconds. 78.986.65 % and 99.3799.58% are the OD segmentation sensitivity and specificity achieved on these three databases. The proposed method demonstrates acceptable robustness on normal and pathological signs retinal images. Focused experimental results reveals the superior performance of presented work with respect to the methods demonstrated in literature.

    Abstract: The main purpose of this research paper is to develop a simple automated system for the accurate diagnosis of Attention Deficit/Hyperactivity Disorder (ADHD) using the Adaptive Neuro-Fuzzy Inference System (ANFIS). The designed diagnostic system has two stages- primary and secondary. In the primary stage, a hierarchical fuzzy-based short version of the gold diagnostic tool Connors scale has been implemented to evaluate the behavioral aspects in a fast and simple manner. The secondary stage targets the two main abilities of brain functionality- attention and perception. The determining traits were extracted from ERP components, especially the P300 wave, using peak amplitude and average latency rate. The proposed secondary diagnostic stage is based on Takagi-Sugeno fuzzy inference system and it integrates the features of both artificial neural network and fuzzy logic into a single framework. The system accuracy is 99.3% in classification, i.e., ADHD vs. Normal and 88.78% in severity level (Normal/Low, Medium and High) of ADHD. Thus, the proposed model provides an adaptive and better alternative to ADHD diagnosis.

    by Bhaskar Kumar Madeti 
    Abstract: ABSTRACT: The present work aims at developing a representation of all the forces by first drawing the free body diagrams of the knee and hip joints. In order to do force analysis one needs to study knee and hip anatomy. With the aid of MRI Scan data, the moments of the forces are computed so as to solve the equilibrium equations. A 3-dimensional (3-D) finite element analysis is generated to represent the real world situation as closely as possible. The accuracy is improved using image processing commercial software on Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) scans. The analysis was conducted for body weights of 600 N, 1000 N and 1500 N for each of the possible postures during various activities. One important recommendation that can be made from present work is that in order to find proper replacement of human knee and hip joint, one needs to collect CT scan slices and then create 3D models performing F.E analysis by selecting the persons weight. In other words the selected implant must be customized for the patients weight, rather than making the choice by rule of thumb as in common practice in hospitals today.

    by Rahul Shreyas, Gopika Kumari 
    Abstract: This work aims at identifying lung cancer into various classes of carcinomas or as a normal-lung, with the aid of an artificial neural network classifier. One thousand input attributes obtained from multiple modality images of the lung, and four output classes are defined. Existing works in the area choose to maximize the accuracy of classification as the primary goal of their researches. However, the reduction of the process complexity has been a relatively untouched area. Few of the available works have tried out the possibilities of reducing the number of input features. This work aims at modeling an optimum Back Propagation Network (BPN) model, by reducing the input feature count and by optimizing the number of neurons in each layer of the BPN classifier without compromising the accuracy. This work incorporates Artificial Fish Swarm Optimization (AFSO) and Evolutionary Algorithm (EA) and proposes a hybrid AFSO-EA for reducing the input feature set. This work also configures a BPN model, where the number of neurons in each hidden layer is optimized using the same hybrid method. The investigation results reveal that the proposed hybrid AFSO-EA technique generates a BPN model, which can achieve 97.5% classification accuracy, with much less computational overhead, than the existing methods.

    by Abdullah Jafari Chashmi, Mehdi Chehel Amirani 
    Abstract: Primary recognition of heart diseases by exploiting computer-aided diagnosis (CAD) machines, decreases the vast rate of fatality among cardiac patients. Recognition of heart abnormalities is a staggering task because the low changes in ECG signals may not be exactly specified with eyesight. In this paper, an efficient combination classification model using Grasshopper Optimization Algorithm (GOA) and support vector machines (SVMs) called GOA-SVM for ECG arrhythmia diagnosis is proposed. In this approach, the combination of Discrete wavelet transform and higher-order statistics is used to feature extraction and the entropy-based feature selection method. The proposed method has been compared with PSO-SVMs and SVM-RBF kernel function for classifying the five classes of heartbeat categories. Our proposed system is able to classify the arrhythmia classes with high accuracy (99.66%). The simulation results show that classification accuracy in SVM-GOA method is better than SVM-RBF and Neural Network classifier.

    Abstract: An outline which defends tolerant details during facts transfer be necessary for medical management systems. On the way to attain safety and confidentiality for facts transfer, a consent based access control system was proposed. It grants the agreement by distributing token to the data client, where the permission can only be created by official client. Thus the information stored inside the data centre can be accessed only when the data requester has the token, which is similar to the token already present inside the data centre. If the confirmation of data centre is valid, the data requester can access the original information of the user. Eventually, the user will be notified by the data centre to deserve that there is no misuse outside consent. The anticipated consent based access control method is compared with existing methods to achieve less time utilization and low computational overhead.

    Abstract: According to the statistics of World Health Organization (WHO), there are about 466 Million people (About 5% of the total population worldwide) are hearing impaired and 34 million of them are children. It is estimated that by the 2050, there will be almost 900 Million people suffering from hearing disability. In India, there are 63 Million people with hearing impairment. Hearing aid prices range from ?20,000 for a basic device to ?2,50,000 for a premium hearing aid. People with hearing disabilities should not have to spend so much money to enable a sense that normal people take for granted. One of the main problems faced by a deaf person is that they find it difficult to have casual conversations because it is hard for them to follow what others are speaking. This can be addressed simply using a mobile application. We present a frugal and affordable system that could show the direction of the speaker along with the speech in text format in real-time. This can be achieved by Sound-Localization and Speech-to-Text conversion. Sound-Localization is a technique used to identify the direction of the source of the sound. There are Speech-to-Text tools that can generate text from a speech in real-time.

  • An efficient AR modeling based Electrocardiogram signal analysis for Health Informatics   Order a copy of this article
    by VARUN GUPTA 
    Abstract: Today health informatics not only require correct, but also timely diagnosis much before the occurrence of critical stage of the underlying disease. Electrocardiogram (ECG) is one such non-invasive diagnostic tool to establish an efficient computer-aided diagnosis (CAD) system. In this paper, autoregressive (AR) modeling is proposed that is an efficient technique to process ECG signals by estimating its coefficients. In this paper, two parameters viz. Atrial Tachycardia (AT), and Premature Atrial Contractions (PAC) are considered for evaluating the performance of the proposed methodology for a total of 17 recordings (6 real time and 11 from MIT-BIH arrhythmia database). As compared to K-Nearest Neighbor (KNN) and Principal Component Analysis (PCA) with AR modeling [ also known as Yule-Walker (YW) and Burg method], KNN classifier coupled with Burg method (i.e. Burg+KNN) yielded good results at model order 9. A sensitivity (S_e) of 99.95%, specificity(Sp or PPV) of 99.97%, detection error rate (DER) of 0.071%, accuracy(Acc) of 99.93% and mean time discrepancy (MTD) of 0.557 msec are obtained. Consistent higher values of all the performance parameters can lead to the development of an autonomous CAD tool for timely detection of heart diseases as required in health informatics.

  • A Supervised Learning Model for Medical Appointments No-Show Management   Order a copy of this article
    by Ines Ferreira, André Vasconcelos 
    Abstract: A no-show is a phenomenon that leads to an efficiency decrease in various sectors, including in the health care sector. This research proposes the usage of supervised learning techniques to predict medical appointments no-shows occurrence and to find patient replacements to fulfil last-minute vacancy slots. The prediction is performed using a classification algorithm that computes the probability of no-show for each patient based on features that have shown to influence his or her decision, such as the waiting time, the day of the appointment and the number of previous no-shows, among others. The features are extracted from two distinct healthcare datasets. To reduce the occurrence of no-shows, the system sends reminders and then, the prediction of no-show is performed days before each appointment, so that there is still time to find a replacement, if necessary. In order to select the most suitable classification algorithm, a 10-fold cross validation is used to perform a comparative analysis among the most used algorithms applicable to this type of classification problems, namely Logistic Regression, k-Nearest Neighbors, Random Forests and Gradient Boosting. This research uses four metrics to assess the algorithms performance, including accuracy, precision, recall and f1-score. The Gradient Boosting algorithm proved to have the best performance in estimating no-shows.

  • Sentiment Analysis of an Epidemic: A case of Nipah Virus in India   Order a copy of this article
    by Jayan V, Sreejith Alathur, Rajesh R. Pai 
    Abstract: Data in social media and other news media can have an impact on the decision-making process of the Government and the citizen if properly examined. The mode and pace of dissemination in both media leads to an increase in the delivery of misinformation. This affects the economy of the country and people's mental health. The government must formulate the required measures to counter the proliferation of fake messages and disinformation in the media, which would otherwise lead to an unnecessary burden. Regulation of health communication during the period of epidemic is important, as it has an effect on the mental health of users of the media. The study assesses the emotions of health communication in social media and online news media in the context of the Nipah Epidemic in India during 2018.

    by Donald Douglas Atsa'am, Ruth Wario 
    Abstract: This research deployed the agglomerative hierarchical clustering to extract clusters from the coronavirus disease 2019 (COVID-19) data based on the morbidity and mortality of the novel virus across 206 countries, territories and areas. As of 2nd April, 2020, a total of 896,475 confirmed cases were reported across the world. Three clusters were extracted from the data on the bases of morbidity and mortality of COVID-19. These include: low-confirmed-cases, low-new-cases, low-deaths and low-new-deaths countries [Cluster 1]; medium-confirmed-cases, low-new-cases, medium-deaths, and medium-new-deaths countries [Cluster 2]; high-confirmed-cases, high-new-cases, high-deaths, and high-new-deaths countries [Cluster 3]. It is recommended that, to contain the pandemic, countries within a cluster should cooperate, share information and learn from mistakes or strategies (as the case may be) of the countries in other clusters. Among other benefits, this can prevent countries within the low-confirmed-cases cluster from progressing to the high-confirmed-cases cluster.

    by K.V. Shriram, Pranav B, Saravanan G, Merin K. John, Athira Sasidharan 
    Abstract: Autism Spectrum Disorder (ASD) is a developmental disorder which can be characterized by social and communication impairments, slow learning, combined with limited interests and repetitive behaviors. It affects as many as one in 59 children and is more prevalent in boys with one in 38 diagnosed with Autism Spectrum Disorder. But due to the social stigma associated with mental health and psychological issues, especially in countries like India, most cases go unreported or symptoms ignored. This project is an attempt to help address this issue by providing a means to assist in diagnosing ASD using telemedicine and also to provide an interactive and effective means of learning for children diagnosed with ASD or children with slight learning disabilities. The system features games that have been proven to be effective with children diagnosed with ASD. The virtual reality which is being speculated to be a powerful tool in helping children with learning difficulties has been used to enhance the effectiveness of these games. The concept of dynamic difficulty is also integrated into the game in order to increase or decrease the challenge of each level depending on the performance of the child which further increases the effectiveness of the game.

    by Vimal Kumar, Shriram K Vasudevan, Nitin Dantu 
    Abstract: The COVID-19 pandemic has shocked the globe with an enormous number of people infected and a large death toll across several nations. Many people lost their loved ones and 350,000 death toll passed globally. By this time more than five million people have been affected. A deadly virus has many victims but no country could stand out when it comes to producing a vaccine. The virus is so dangerous that it spreads rapidly through human contact and a person who is infected will infect around 600 people a month. It is so fast that more than 50,000 people are affected in one day in some countries and more than 1,000 people die in one day. The present situation is so bleak, and if not contained by social distance, it can get even worse. There are many patients but not enough doctors and hospitals to treat them as the infection grows exponentially. No doctor can examine Chest X-ray in thousands and have fast turnaround. We want to create a solution to reduce the workload on doctors, to easily determine whether a Chest X-ray pneumonia is due to coronavirus or not, so that the rapid spread can be controlled and proper cure could be given to patients. Here we also add the distributed ledger technology called blockchain, which helps in monitoring the patient health data and thus it helps in having the complete history of the patient.

  • Analysis of Dermal Activity and Skin Images for Diabetic Kidney Disease   Order a copy of this article
    by Valli MN, Sudha Singaram, Kalpana Ramakrishnan, Soundararajan Periasamy 
    Abstract: Any electrical input to skin, changes the ion concentration in sweat, leading to variations in electro dermal activity (EDA) and hence in skin conductivity. Structurally, the pores and connecting tissues contribute to skin texture. Diabetes leads to micro-vascular complications thus affecting the innervations of C-nerve fibers, thereby skin conductivity and micro texture also changes. Diabetic kidney disease (DKD) is another condition under which hydration level and urea in serum and sweat varies leading to dermal changes. Therefore EDA and microscopic-images are acquired from volunteers catering to normal, diabetic and DKD. Features are extracted after convolving EDA signals with Morlet-wavelet and pre-processing the micro texture image for hair removal and enhancement. An expert system is designed to take these features as input and for broad classification. Result of this study demonstrates the influence of serum urea on skin conductivity and texture, thereby enabling skin based method of diagnosing diabetics and DKD.

    by Dewi Masyithah Darlan, Delfitri Munir, Agung Putra, Nelva Karmila Jusuf 
    Abstract: Regulatory T-cell (Treg) defects may cause autoreactivity of both T and B cells leading to autoimmune disease, including in Systemic lupus erythematosus (SLE) disease. Those defects were characterized by decreased expression of CD4, CD25, and FoxP3, thus restoring the Treg expression can reverse autoimmunity into immune tolerance into a normal immune response. Mesenchymal stem cells (MSCs) have immunomodulatory properties to control inflammation milieu, including in SLE inflammation by releasing TGF?1, IL-10, and PGE2, thus MSCs can generate Treg cells. However, the regulation of Treg by MSCs-released TGF?1 in human SLE remains unclear. This study aims to analyze the role of MSCs-released TGF?1 in generating CD4+, CD25+, Foxp3+expression in T-reg cells of human SLE PMBCs. This study used a post-test control group design using the co-culture of PBMCs from SLE patient and human umbilical cord MSCs (hUC-MSC) as the subject. This study was divided into 5 groups; sham, control, and treatment group treated by co-cultured hUC-MSC to PBMCs with ratio 1:1 (T1), 1:25 (T2), and 1:50 (T3) for 72 hours incubation, respectively.

  • DEPRESSION CLASSIFICATION AND RECOGNITION BY GRAPH-BASED FEATURES OF EEG SIGNALS   Order a copy of this article
    by Ahad Mokhtarpour, Faezeh Bashiri 
    Abstract: Major depressive disorder(MDD) is one of the main subjects in world health so its diagnosis is important for researchers. Electroencephalography(EEG) is one of effective tools in brain psychological disorders diagnosis which any change in brain function is reflected in signals. By EEG signal analyzing, some disorders like MDD can be recognized. In this paper EEG signals are firstly mapped to four different visibility graphs and several features are extracted from each graphs. Then feature numbers are reduced by principal component analysis(PCA) and depressive and normal classification is done by support vector machine(SVM). In this paper, classification results by combining all four graph features are compared with each graph features individually and the results show that by combining features lower classification error and better accuracy is achieved. The classification accuracy of depression classification by mixed features is 100 percent which means the proposed method can classify all of them correctly.

    by Arathi Thiruvoth, Rahul Chingamtotatil 
    Abstract: Image denoising is a significant pre-processing technique that plays a vital role in medical image processing. Image denoising is the process of removing noise from an image and is a trade-off between noise removal and preservation of significant image details. This paper encloses a sparse representation based denoising technique called Multi Median Variance-Independent Component Analysis (MMV-ICA). Investigation evident, the incorporation of MMV ICA reveals superior denoising results over contest techniques under various noise attacks and noise level conditions. The proposed denoising algorithm based on sparse and redundant representations over learned dictionaries. The dictionary is trained using the corrupted image, and after that, the dictionary is adapted to achieve sparse signal representations. MMV-ICA algorithm presented in this paper makes use of a patch-based dictionary creation method. The paper presents the results of the MMV-ICA denoising technique, which are found to be in par with the existing sparse based denoising methods.

  • Clinical Decision Support for Early Diagnosis and Intervention in Multiple Sclerosis   Order a copy of this article
    by Shankar Srinivasan, Jojy Cheriyan, Dinesh Mital, Riddhi Vyas 
    Abstract: Multiple Sclerosis (MS) is one of the most common neurological disorders and cause of disability among young adults in North America and Europe1. It is a non-communicable disease with no cure, debilitated by physical and mental impairments2. Recent reports show an increase in the incidence of MS in United States, more than double of the past estimate. The average period to diagnose MS still ranges from 6 months to 3 years. Studies suggest that early diagnosis and intervention can delay the progression of the disease and improve the quality of life4-6. Until today no clinical decision support exists that could be used to assist clinicians in diagnosing MS at an early stage. This study is conducted to assess the need and explore the quantifiable predictors that could be used for helping clinicians in early detection of disease activity. A review of literature followed by a quasi-experimental approach has been done to collect predictors and analyze the trending incidence of MS in United States. This study reports its preliminary analysis by concluding that currently no clinical decision support system (CDSS) exists to diagnose MS at the point of care. Predictors are available to design a clinical decision support tool for Multiple Sclerosis at the point of care that can help clinicians in the early diagnosis and intervention.

    by Mahadevi S., Shyam S. Kamath, Pushparaj Shetty D. 
    Abstract: The propagation of the new pandemic COVID-19 is more likely linked to human social relations and activities. A Social Network can be used to describe these human relationships and activities. Understanding the dynamic properties of disease dissemination through diverse Social Networks is critical for effective and efficient infection prevention and control. With the frequent emergence and spread of infectious diseases and their impact on large areas of the population, there is growing interest in modelling these complex epidemic behavior. Such an approach could provide a stronger decision-making method to tackle and control disease. In this paper, a transmission network is developed using the South Korean data, and the study of the network is carried out using Graph Energy Centrality. This measure of centrality allows us to recognize the primary cause of the spread of the virus within the established network by ranking the nodes of the network based on graph energy. The identified primary cause can then be isolated, which can prevent further spread of infection. We have also considered the Novel_Corona_Virus_2019_Dataset from Johns Hopkins University to analyse epidemiological data around the world.

    Abstract: Heart diseases are considered to be one of the main causes of death around the world. The most reliable method for heart disease diagnosis is angiography, which is costly, invasive and has the risk of death. This study applies data mining techniques to construct a heart disease diagnosis predictive model. In this study, variations of Decision Tree (DT), Support Vector Machine (SVM) and voting algorithms are applied on UCI heart data repository. We show that integrating medical knowledge and statistical knowledge as well as fine tuning the related parameters of the models lead to an effective heart disease diagnosis model. We use two methods for implementing the proposed model. First, we use K-fold cross validation to create the model. The obtained results demonstrate that, voting algorithm and Random Forest, respectively with the accuracy of 86.42% and 85.71%, in comparison with other existing methods can more accurately identify patients with heart diseases. In the second modelling method, we shuffle dataset then split it into two datasets as Train/Validation and Test datasets. We use K-fold cross validation on Train/Validation dataset and then calculate the accuracy of the model with Test dataset. The results of this method demonstrate that, voting algorithm and random forest respectively with the accuracy of 87.5% and 90.0%, in comparison with other existing methods perform well in identification of patients with heart diseases.

    by Venkata Subbareddy Konkula, Nirmala Devi 
    Abstract: To break the chain of COVID-19, a powerful and fast screening system is required which identifies the COVID-19 affected cases quickly such that the appropriate measures like Quarantine or treatment can be taken. The traditional Genetics assisted chain reaction test is found to have significant misclassification rate followed by more time consuming. To solve this problem, in this paper we have introduced a new model for COVID-19 detection based on Chest X-Ray (CXR) Images and Convolutional Neural Networks (CNNs). The proposed model is an automatic detection model which considers the CXR image as input and performs an in-depth analysis to discover the COVID-19. The proposed CNN model is a very simple and effective which is composed of five convolutional layers and three pooling layers. Every convolutional layer has different sized filters and different number of filters, which extracts all the possible features from CXR image. Simulation experiments are conducted over a newly constructed dataset based on the publicly available CXR (both COVID-19 and Non-CVOID-19) images. Simulation is done under two phases; 3-class and 2-class and obtained an average accuracy of 92.22% and 94.44% respectively. Thus the average accuracy is measured as 93.33%

    Abstract: COVID_19 is a virus that infects the respiratory system and causes pneumonia, kidney failure, and other health issues. The purpose of early diagnosis of COVID_19 is the fastest time to keep healthy cells for patients. A checkup for COVID_19 has been performed for patients whose ages were between (85-25) years by CT scan and Laboratory-Analysis (PCR) and X-ray and PET/CT scan. CT scan is considered the more clear method for the early diagnosis for COVID_19 because of the production of clear radiographic image quality and high-resolution and three-dimensional of a patient's chest in tow views (anterior-posterior view and the lateral view). In addition to that, a CT scan is more readily and cheaper, and more available in the hospital, also it takes less time to check the patient's chest.

    Abstract: The most severe kind of skin cancer is malignant melanoma. It can grow anywhere on the body. Its exact cause is still unclear but typically its caused by ultraviolet exposure from sun or tanning beds. Its detection plays a very significant role because if detected early then its curable, before the spread has begun. In this paper a computationally improved (using Principal Component Analysis, PCA) feature extraction method named 3D color texture feature (CTF) is represented which is well discriminative.

    by Pallavi Mulmule, Rajendra Kanphade 
    Abstract: Cervical Cancer is the found in women and is the global life threatening problem. Papanicolaou test is the well-known technique used for diagnosing the cancer at the early stage. However, the pathological screening is manual, tedious and time consuming process. Therefore, the proposed method employs adaptive fuzzy k means clustering to segment the cell containing nucleus and cytoplasm from the unwanted background from the pathological pap smear image. Thereafter, the 40 features are extracted from the segmented images based on the shape, size, intensity, orientation, color, energy and entropy of nucleus and cytoplasm individually. Finally, supervised classification approach utilizing multilayer perceptron with three kernel and support vector machine with five different kernels as the classifiers to predict the cancerous cells. The classifier is trained and tested on benchmark database with 280 pap smear images. The performance of these two classifiers are evaluated and found that the MLP classifier with hyperbolic tangent activation function outperforms in all the performance criterias as compared to SVM classifier with classification accuracy of 97.14%, sensitivity of 98%, Specificity of 95% and positive predictive value of 98%.

  • MRI DENOISING: A SPARSE ICA BASED DICTIONARY LEARNING APPROACH   Order a copy of this article
    by Arathi Thiruvoth, Rahul C 
    Abstract: Image denoising is an important preprocessing technique in medical image analysis. The presence of noise in images can lead to degradation in its quality. Image denoising is the process of removing noise from an image and is basically a tradeoff between noise removal and preservation of significant image details. This paper presents a new sparse processing based denoising algorithm, the MMV-ICA (Multi-Median Variance-Independent Component Analysis) denoising algorithm. The MMV-ICA algorithm has been implemented and applied to medical images and the results are analyzed. Various noises which affect medical images are also considered. The proposed denoising algorithm is based on sparse and redundant representations over learned dictionaries. The dictionary is trained using the corrupted image. Thereafter, the dictionary is adapted to achieve sparse signal representations. MMV-ICA algorithm presented in this paper makes use of a patch based dictionary creation method. The paper presents the results of MMV-ICA denoising technique, which are found to be in par with the existing sparse based denoising methods.

    by Ghaith K. Sharba, Mousa K. Wali, Ali H. Al-Timemy 
    Abstract: The aim of this study is to suggest a system for classification of seven classes of shoulder girdle motions for high-level upper limb amputees using pattern recognition (PR) system. In the suggested system, the wavelet transform was utilised for feature extraction and extreme learning machine (ELM) and linear discriminant analysis (LDA) were used as classifiers. The data were recorded from six intact-limbed subjects, and four amputees, with eight channels involving five electromyography (EMG) channels and 3-axis accelerometer. The study shows that the suggested pattern recognition system has the ability to classify the shoulder girdle motions with 92.67% classification accuracy for intact-limbed subjects and 87.67% classification accuracy for amputees by combining EMG and accelerometer channels. The outcomes of this study show that non-invasive PR system can help to provide control signals to drive a prosthetic arm for high level upper limb amputees.

  • Automated EEG-based epilepsy detection using BA_SVM classifiers   Order a copy of this article
    by Aya Naser, Manal Tantawi, Howida A. Shedeed, M.F. Tolba 
    Abstract: Epilepsy is a neurological disorder which affects individuals all around the world. The presence of epilepsy is recognised by seizures attacks. EEG signals can provide useful information about epileptic seizures. Unlike most of the existing studies which consider only two classes, this paper proposes an automatic EEG-based method for epilepsy detection which has the ability to distinguish between the three classes; normal, interictal (out of seizure time) and ictal (during seizure). In the proposed method, Rènyi entropy, line length and energy are computed from each of the five sub-bands extracted from an EEG segment using digital wavelet transform (DWT). Thereafter, the extracted features are fed into BA-SVM classifiers trained using divide and conquer strategy for classification. The BA-SVM classifier is a support vector machine (SVM) classifier whose parameters are optimised using BAT algorithm. The popular Andrzejak database was utilised for training and testing purposes. The average accuracies for all considered cases are more than or equal 95%. Thus, the various experiments and comparisons accomplished in this study reveal the efficacy of the proposed method.

    by Nivaashini Mathappan, R.S. Soundariya, Aravindhraj Natarajan, Sathish Kumar Gopalan 
    Abstract: Breast tumour remains a most important reason of cancer fatality among women globally and most of them pass away due to delayed diagnosis. But premature recognition and anticipation can significantly diminish the chances of death. Risk detection of breast cancer is one of the major research areas in bioinformatics. Various experiments have been conceded to examine the fundamental grounds of breast tumour. Alternatively, it has already been verified that early diagnosis of tumour can give the longer survival chance to a patient. This paper aims at finding an efficient set of features for breast tumour prediction using deep learning approaches called restricted Boltzmann machine (RBM). The proposed framework diagnoses and analyses breast tumour patient's data with the help of deep neural network (DNN) classifier using the Wisconsin dataset of UCI machine learning repository and, thereafter assesses their performance in terms of measures like accuracy, precision, recall, F-measure, etc.

    Abstract: The indirect immunofluorescence (IIF) test with human epithelial type-2 (HEp-2) cells as substrates is the gold standard for anti-nuclear antibodies (ANA) test to diagnose autoimmune diseases. The specialists in the laboratory visually examine the specimen under microscope to recognise the staining patterns and generate the report. So ANA test is subjective and needs systemic automation for bioinformatics. In this view international benchmarking initiatives were organised by IAPR in the last six years. In this paper the state of the art on IIF HEp-2 cells classification task was analysed. This paper highlighted the original aspects with the detailed discussion of the published methods. Design choice verses performance was analysed.

  • Query optimisation with weighted fish school search in ontological database with application of bioinformatics   Order a copy of this article
    by R. Jaya, C.S. Pillai, R. Jagadeesh Kannan 
    Abstract: Making queries from large ontological database has a severe problem of generating query plans as it is made in form of left tree search form. This restricts the querying for composite applications and speed of acquiring query results. In such a scenario the most prominent approach is to optimise the indexing of graph nodes in ontological database and many evolutionary and particle of swarm optimisation (PSO)-based approach had already been attempted. However, loss of diversity and unanticipated convergence causes the solution to remain sub-optimal. In this study we present a weighted fish school searching-based query optimisation technique owing to its scalability and self control functioning with the application of bioinformatics. It creates probabilistic logic-based weight system for the fish school search in a hierarchical tree form which results in increased accuracy when put in comparison with standard PSO-based methods and its other variants.

    by J. Leelavathy, S. Selva Brunda 
    Abstract: Enormous amounts of medical data are being collected by several well-developed hospital information systems (HIS) in the form of patient records in hospitals. The hidden patterns and relationships contained in this data are identified using various data mining techniques which have drawn increasing world-wide attention in the recent years. As a result of which, a good number of medical decision support systems (MDSS) have been developed. These are computer systems designed to assist physicians or other healthcare professionals in making clinical decisions for the given patient's symptoms and medical history. Inspired by the existing systems, the model proposed in this paper aims at making a knowledge sharing collaborative platform for doctors which serves as a realistic and effective medical decision support system. It is important because it provides vital information from different data sources. It has several challenges like scalability, response time, heterogeneous data formats. This paper does a detailed study of different challenges in understanding about medical information that can be provided to users in a better manner. A framework named intelligent healthcare framework (IHCF) is being proposed in this paper detailing the services and support to society.
