Dietary Macro-nutrients Intake And Risk Of Obesity & Type II Diabetes: To compute a model to predict probability of developing Hypertrophic Obesity and Type II Diabetes based on the macro-nutrient intake levels.
by Shalini Pattabiraman, Riddhi Vyas, Shankar Srinivasan
Abstract: Good nutrition and healthy diet are the primary pre-requisites for a healthy and balanced lifestyle. Improper proportions of dietary macronutrients in the food lead to implicated risk of chronic diseases. Energy consumption and energy expenditure should be balanced in order to maintain the body mass and to avoid the complication resulting from excess body weight. Obesity is the global cause of many chronic diseases, which is why diet has an important role towards the risk of incidence of chronic diseases such as diabetes, high blood pressure and cardiovascular diseases. The purpose of this study is to compute a model to predict the risk for obesity and diabetes based on the macro-nutrient intake levels (High/Low). The SAS (Statistical Analysis Software) datasets from NHANES (2013-14) were extracted, then using descriptive statistical analysis (chi-sq & Pearsons correlation) and logistic regression analysis in SAS, a model is computed for each disease with significant predictive macro-nutrient intake variables. An ROC (Receiver Operating Characteristic) curve and predicted probability plots were analyzed for the accuracy of the model. It was found that the significant predictor variables identified for each disease risk corroborates with the literature studies, but further studies may be required with normalization of the data in order to validate the results of this study.

A Framework for Disease Diagnosis Based on Fuzzy Semantic Ontology Approach
by Nora Shoaip, Shaker El-Sappagh, Sherif Barakat, Mohammed Elmogy
Abstract: In this paper, we propose an OWL2 ontology based on SNOMED CT standard medical terminology. It can provide significant help to support physicians in diabetes risk level diagnosis problem. It explicitly defines the semantics of diabetes knowledge by using ontology and deal with the imprecise and vague nature of its data by using fuzzy set theory. It involves building a complete linguistic fuzzy rule-base that can integrate knowledge from expert and CPG with knowledge extracted from training data and knowledge extracted from the semantic model. This step enhances the level of automation and interoperability of CDSS. The importance of our work comes from the current lack of studies related to the integration of the formal integration between the ontology semantics and FES reasoning, especially in the medical domain. The ontology acts as an integral and complementary component of the FES.

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 Aya Naser, Manal Tantawi, Howida Shedeed, Mohamed Tolba
Abstract: Epilepsy is a neurological disorder which affects individuals all around the world. The presence of Epilepsy is recognized 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, R`enyi 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 optimized using BAT algorithm. The popular Andrzejak database was utilized 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.

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.

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.

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.

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
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
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
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
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
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.

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
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
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%.

by Djamaleddine DJELDJLI, Fethi BEREKSI REGUIG, Choubeila MAAOUI
Abstract: Video Photoplethysmography has been a resurgence of interest of researchers from different domains of science, driven by the demand of low cost, comfortable, contactless, non-stressful, simple and portable technology for physiological parameters measurements. In this paper, we propose a robust and simple method for remotely measure heart and respiratory activities through video Photoplethysmographic signal recordings using a low-cost webcam. The Video Photoplethysmographic signal is detected from colour video recording of a human face in an ambient light environment. The image and signal processing operations steps are minimized and optimized. Three critical aspects are endorsed during the implementation. These are performances, reduced computational time and low computational complexity. Experimental heart rate, breathing rate, and heart rate variability obtained results on 20 healthy subjects show a high correlation with those obtained using an approved contact sensor. The heart rate error obtained in the proposed method is

Predicting Treatment Outcome of Spinal Musculoskeletal Pain Using Artificial Neural Networks: A Pilot Study
by Ali Al-yousef, Haytham Eloqayli, Anwar Almoustafa, Mamoon Obiedat
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.
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
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
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. Red and Green color blindness is more common whereas Blue color blindness- rare type and people cannot distinguish blue or yellow and both the colors are seen as a color vision test using LabVIEW for the early detection of color blindness and helps to prevent Achromatopsia. This virtual instrument is ideal for mass screening in education institutions, clinics, etc., for the early detection of color blindness.
Keywords: Achromatopsia; Colorblindness; Dichromacy; Ishihara chart.
Performance evaluation of a computational model for brain shift calculation
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
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
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
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 of this work 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 polymerization, combined with the minimization of different long bone metastatic lesions, 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 polymerization. The results showed that the polymerization heat release caused thermal necrosis in all models with a cement mantle filling in around the intramedullary nail and the necrosis largest area was predicted with CMW3

Implementation of non-contact bed embedded Ballistocardiogram (BCG) signal measurement and valvular disease detection from this BCG signal
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
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.

Microfluidics Dielectrophoresis Device for Potential Cancer Cell Detection and Separation
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
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.

Frequency Domain Analysis of Gray Level Intensities for Extraction of Optic Disc in Retinal Images
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.

Adaptive Neuro-fuzzy based Attention Deficit/Hyperactivity Disorder Diagnostic System
by ANOOP KUMAR SINGH, Deepti Kakkar, Tanu Wadhera, Rajneesh Rani
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.

MODELING AND ANALYSIS OF KNEE AND HIP JOINTS IN HUMAN BEING
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 Disha Sheth (Kothari), Riddhi Vyas, Shankar Srinivasan
Abstract: ABSTRACT:Liver diseases can be diagnosed by interpreting enzyme abnormality pattern and patient characteristics. Despite growing evidence suggesting different causes, there is a need to explore the risk factors which lead to liver diseases in different population. NHANES Data (2015-2016) was investigated for gender, age, race and country of birth in patients with high liver enzymes values. Different elements were also studied for significant liver disease risk based on odds ratio, 95% confidence interval and relative risk using Fisher Exact Test. Results showed US-born, Non-Hispanic white young males had high values for liver enzymes, demonstrating greater risk in such population for liver diseases. Odds ratio (<1.0); P-value of significance (<0.0001) indicated negligible risk associated with all elements - iron overload, diabetes, smoking, alcohol, blood pressure, total cholesterol, obesity, total protein, albumin and total calcium. Validation studies were also performed using NHANES data (2013-2014), authenticating the results obtained.

by Amber Khan, Mainuddin , Moin Uddin, Parikshit Vasisht
Abstract: Microwave imaging is one of the emerging technologies for early detection of breast cancer among women having dense Mammographic densities. One of the critical and valuable components of an accurate, effective and compact, involving minimum risk - Microwave Imaging system for early breast cancer detection is an Ultra Wideband (UWB) antenna. A novel, compact elliptical UWB microwave antenna is presented in this research article that might be suitable for early breast cancer detection. The simulation of antenna structure is carried out using HFSS13 FEM based EM software. The simulation results yield better UWB response. The antenna structure provides a wide practical fractional bandwidth of more than 156%. A significant performance factor of the proposed antenna is its ability to provide sufficient gain level for short distance communication. Thus, the proposed antenna is a strong candidate for design and development of microwave imaging system for early detection of breast cancer among women with dense Mammographic densities.

Diagnosing Lung Cancer with the aid of BPN in associate with AFSO-EA
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.

An automatic ECG arrhythmia diagnosis system using Support Vector Machines optimized with GOA and entropy-based feature selection procedure
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.

Protection of Encrypted Medical Image using Consent based Access Control
by Mancy Lovidhas, Maria Celestin Vigila S
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.

An Innovative Hearing-Impaired Assistant with Sound Localization and Speech to Text Application
by Balaganesh Baskar, B.V. Damodar, R. Dharmesh, K.R. Tharunkarthik, K.V. Shriram
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
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
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.
Keywords: No-show; Health Care; Supervised Learning; Classification Algorithms; Cross Validation.
Sentiment Analysis of an Epidemic: A case of Nipah Virus in India
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.

Hierarchical Cluster Analysis of the Morbidity and Mortality of COVID-19 across 206 Countries, Territories and Areas
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.

Virtual Reality-Based Real-Time Solution for Children with Learning Disabilities and Slow Learners An Innovative Attempt.
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.

An Innovative Deep Learning Approach for COVID 19 Detection with X-Ray Images and Infected User tracking through Blockchain
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
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.

MSCs-released TGF?1generate CD4+CD25+Foxp3+ expression in T-reg cells of Human SLE PBMC
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. The expression of T-reg was assessed by flow cytometry assay, whereas the TGF?1 using Cytometric Bead Array (CBA).This study showed a significant increase in Treg cell expression (P

DEPRESSION CLASSIFICATION AND RECOGNITION BY GRAPH-BASED FEATURES OF EEG SIGNALS
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
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.

Bio-Medical Analysis of Breast Cancer Risk Detection based on Deep Neural Network
by Nivaashini M, Soundariya R S
Abstract: - Breast tumor remains a most important reason of cancer fatality among women globally and the pathetic condition is that 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. Bioinformatics can be narrowly defined as a field at the crossroads of biology and computer engineering, responsible for the storage, distribution, and analysis of biological information. Various experiments have been conceded to examine the fundamental grounds of breast tumor. Alternatively, it has already been verified that early diagnosis of tumor can give the longer survival chance to a patient. Consequently, early prediction of breast tumor is very critical to rescue a patients life. To deal with this issue, in the proposed framework a model with deep learning techniques has been introduced to identify breast tumor at primary stage. This paper aims at finding an efficient set of features for breast tumor prediction using deep learning approaches called Restricted Boltzmann Machine (RBM). The proposed framework diagnoses and analyzes breast tumor patients 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.

QUERY OPTIMIZATION WITH WEIGHTED FISH SCHOOL SEARCH IN ONTOLOGICAL DATABASE WITH APPLICATION OF BOINFORMATICS
by Jaya Raju, 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.
