Optimized DBN for Effective Enhancement of Ultrasound Images with pelvic Lesions
by Sandanand L. Shelgaonkar, Anil B. Nandgaonkar
Abstract: Nowadays, the ultrasound modality is the current research areas for lesion analysis. Moreover, it is renowned; the ultrasound images exhibit hassle- free utilization as well as cost effectiveness. In the literature, merely a small number of reliable contributions have been reported from the females for analyzing the pelvic lesions. However, the literature lags with adopting a prominent enhancement procedure to facilitate the diagnosis process. This paper adopts an Optimized Deep Belief Neural (ODBN) network for enhancing the US image of pelvic portions. It considers the higher order as well as lower order statistical characteristics of the image to define the appropriate filter band for image enhancement. The lower order features are optimized to use with the higher order features so that the optimal usage of features is reported here. To optimize the lower order features, an advanced optimization search algorithm named Grey Wolf Optimizer algorithm (GWO) is exploited. The ODBN learns the optimized features and the noise characteristics for precise prediction of the filter bands, which enhance the image substantially over the conventional filter bands. The performance of the proposed method is compared with the conventional methods using the benchmark as well as real-time US images of pelvic lesions. The quality of enhancement is ensured using the renowned measures such as PSNR and ESSIM that exhibit the performance of the proposed approach.

An innovative technical solution to avoid Insomnia and Noise-Induced Hearing Loss
by Shriram K V, Ikram Shah, Sriharsha Patallapalli, Karthikeyan S, S. Subhash Chandran, U. Adithya Bharadwaj
Abstract: The major challenge these days with the increased usage of the mobile phone is loss of sleep (insomnia), increased stress and finally more damages to the health and mental wellness. Most of us have the habit of even keeping the phone underneath the pillow while sleeping. There are people who are now treated for mobile addiction. People are there to use a phone to get sleep sooner. Sleep time is meant for the brain to rejuvenate, organize thoughts and relax. If the sleep patterns are disturbed due to a continuous external commotion, it will result in the subconscious to spend energy and brain space. Hence, it is wise to switch off the music after the person sleeps which most of us do not do as we are already slept by then. Also, wearing headphones for an hour will increase the bacteria in your ears by 700 times. Many researches in the past prove that music is a solution to reduce stress and to bring sleep. But, we, the users are using headphones for music and it causes some dangerous side effects including affecting the sleep and noise-induced hearing loss. There is a strong need to avoid unnecessary health problems which are meant to be avoided. Here, we propose a system which will ensure that the music player is stopped after understanding that the person using it has slept and he no more needs the tunes thereby not disturbing the deep sleep and preventing insomnia and noise-induced hearing loss. Novelty is what we present in this research through making sure if the person has really slept or not. Our innovative system switches off the audio automatically when a person falls asleep. The same can be expanded and improvised to provide analytics to the user as in how many hours did he sleep peacefully, how is his body tuned towards listening to music, how long does he need music, under what conditions does he over listen or under listen etc.

Adaptive Improved Binary PSO Based Learnable Bayesian Classifier for Dimensionality Reduced Microarray Data
by Barnali Sahu, Satchidananda Dehuri, Alok Jagadev
Abstract: This article presents, an adaptive improved binary particle swarm optimisation based learnable Bayesian classifier for dimensionally reduced microarray data. In the first fold of this two-folded work, the problem of dimension has been reduced by unsupervised method of feature reduction. The k-means clustering algorithm has been applied on the microarray data to group functionally redundant genes followed by application of signal-to-noise-ratio ranking technique to generate an intermediate feature subset consisting of most relevant and non-redundant feature subsets. In the second fold, the feature subset has been given to an adaptive binary particle swarm optimisation based learnable Bayesian classifier for simultaneous selection of features and classification. We have conducted an extensive experimental work on a few benchmark datasets to validate its classification accuracy with and without reducing the dimensionality of microarray data. It was observed that our method is not only accepted as a good classifier over methods, which are considered here for comparison but also be treated as an alternative method of reducing dimension of the problem.

Product Unit Neural Network trained by an Evolutionary Algorithm for diabetes disease diagnosis
by Radhwane BENALI, Nabil Dib, Fethi Bereksi Reguig
Abstract: Diabetes disease occurs when the level of glucose in the blood becomes higher than normal because the body is unable to produce the insulin which is needed to regulate glucose. In this study, a new classification method for the diagnosis of diabetes disease was developed. This method is based on a special class of neural network known as product-unit neural networks (PUNN) which was trained by an evolutionary algorithm (EA). We have used EA in order to determine the basic topology of the structure of the PUNN, and to estimate its coefficients weights. The performances of the proposed classifier were evaluated through the sensitivity, the specificity and the classification accuracy using both conventional and 10-fold cross-validation method using the Pima Indian Diabetes (PID) dataset. Obtained results reveal that the proposed approach outperforms several famous and recent methods existing in the literature for diabetes disease diagnosis.

Development of a Serious Game to Enhance Assistive Rehabilitation
by Mauro Bellone, Andrea Martini, Francesco Argese, Piero Cirillo, Italo Spada, Antonio Cerasa
Abstract: The aim of this study is to investigate novel assistive technologies
based on serious gaming for the assessment of postural control and motor
rehabilitation. Previous research already demonstrated that rehabilitation and
physical activities can improve the quality of life of patients, and virtual reality
applications may act as good additional companions during the therapeutic
sessions. Indeed, workout routines supported by serious gaming encourage
patients to train harder, bringing the therapy towards a pleasant game into a
virtual environment. During the game, sensors track the movements of the
players and transfer the data to software components that record a database
from which patients progress can be determined. The acquired measures are
interpreted in the form of new biomarkers, which enable the assessment of
postural control. Such biomarkers are based on a probabilistic approach and
show the capability to discriminate between well-performed exercises and incorrect movements. A long-term experimentation on a specific exercise is
proposed, showing a considerable improvement, ranging from 5\% to 30\%, in
the performance of patients.

An Innovative Solution for prevention of reverse flow of blood in IV set (Intravenous set) using Embedded Systems
by Abhishek SN, Ikram Shah, K.V. Shriram
Abstract: The demand for medicine and doctors is never ending and it is really evergreen as our society has been revolutionized and the life expectancy rate has increased. Everyone starting from a six year old child to 90 year old veteran is aware of all kind of diseases exists as of now, specialization of doctors, which doctor to approach when we have a particular problem and so on. Thus, a common wish prevailing in everyone irrespective of age is that to live long and stay in pink of health. Adding to this point, millions and millions of innovations are being made in the medicinal field every decade to enhance the average life expectancy rate. There are various sectors of engineering that are involved in creating and/or maintaining various medical instruments. Say, from the smallest equipment like syringe to the largest one like CT scan machine have major contributions from the engineering sectors. IV Set (Intravenous set) is one among those substantial inventions in the medicinal field; it is actually used for transferring blood or saline from the IV/fluid bag to the patients body at a speed and pressure that the human body can accept. There is a notable threat associated with using the IV set which most of the doctors and care takers are aware of; When the fluid in the IV bag runs out (gets emptied) the patients blood would start flowing through the IV tube in the reverse direction towards the empty IV bag as the pressure of blood in the human body is more than the pressure experienced by the empty IV bag (diffusion), thus leading to blood loss and pain, at times. Thus the caretakers must be vigilant enough to replace the fluid bag at an appropriate time to avoid blood loss. The innovation proposed here is a solution that would prevent such blood losses and doesnt require manual monitoring of the IV bag thereby stopping the reverse blood flow well in time. This not only prevents blood loss but also reduces the stress for the care takers and pain for the patients. The product is tested and is costing less than 100 USD and is one-time investment for the hospitals.

An inventive and innovative system to detect fall of old aged persons A novel attempt with IoT, Sensors and Data Analytics to prevent the post-fall effects.
by Juluru Anudeep, Gudimetla Kowshik, Popuri Vamsi Krishna, Ikram Shah, K.V. Shriram
Abstract: According to the statistics of NCOA (National Council on Aging) these days rate of deaths 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 taking place. Most of the old aged people are suffering from the back pain, joint pain, knee pain and they mostly are the ones who arent able to walk properly and are mostly constrained to bed. Statistics by north eastern Ohio state reveals that, the rate of emergency room treatment of fall-related injuries in persons aged 75 and older approached 80 per 1,000 per year in women and 60 per 1,000 per year in men. Falls are indications to some critical problems like immobility, fragility of bones and chronic health impairment. Falls in elders vary from that of the falls in kids, as the healing power in the old people slackens with their age. Falls are going to play a crucial role in the health line of the old people. Due to the falls there will even be a huge impact on the heart. Old people with heart diseases when falls suddenly, there is risk of being affected by Tachyarrhythmia which is typically a heart disorder in which the heartbeat raises to an abnormal rate of more than 100 beats per minute which is approximal to an cardiac arrest. So, in order to reduce these type of risks in elderly people , We present a frugal and affordable system that could monitor the motion of the old people and can detect their fall. Detection is not done before the fall or when person remains in rest state, it detects immediately after fall and alerts the concerned persons to do the necessary action to save the person. We use IoT, Sensors and Data analytics to build this system. The system is tested for its functioning and is fool proof.

Transmission and Archiving of Reduced MRI Medical Images
by Hedi AMRI, Med Karim ABDMOULEH, Ali KHALFALLAH, Jean-Christophe LAPAYRE, Med Salim BOUHLEL
Abstract: Medical images are often large. To minimize their file sizes, different compression standards like JPEG, JPEG 2000 and TIFF have been developed, but they can affect the image quality in case of lossy compression. In this paper, we propose a compression method based on image resizing that can reduce the file size to a quarter before its transmission or archiving. When it is received or before its display, the reduced image is enlarged to ensure better visual comfort. This approach is called REPro. In this context, we have used three image reduction techniques namely Square-Square Mesh Decimation, Square-Square filtered Mesh Decimation, the Square-Staggered-Square filtered Mesh Decimation. In addition, we have utilized four enlargement techniques namely Zero padding, Nearest Neighbor interpolation, Cubic Spline interpolation and B-interpolation to resize MRI images. The experimental results prove that the combination of the Square-Square Mesh Decimation with the B-Spline interpolation ensures the minimum distortion of the original image.

by Ashok Dwivedi
Abstract: Recombination influences the evolution of Saccharomyces Cerevisiae. Genomic regions where
recombinations occurs are known as recombination hotspots. There are two kind of hotspots for recombination. The spots where recombination occurs more frequently are called recombination hot spots and regions where recombination occurs less frequently are known as cold spots. In this work, we have formulated methods based on neural network models for the classification of these hot and cold recombination spots on the basis of compositional features of nucleotide sequences. These models were validated using tenfold cross validation technique. The classification accuracy of 83%, 82%, and 78 % were achieved using radial basis function neural network with genetic algorithm, radial basis function neural network and multilayer perceptorn models respectively. Moreover, the performance of these model were evaluated on differenct classification measurements. Furthermore, results indicate that redial basis function neural network with genetic algorithm gives best result.

Analysis of salivary components as non-invasive biomarkers for monitoring chronic kidney disease
by Navaneeth Bhaskar, Suchetha M
Abstract: Saliva, a valuable source of biochemical information, is a potential diagnostic substance that helps to identify many diseases. Studies have revealed that saliva tests help identify many diseases. Saliva test has excellent advantages over blood test as the former can be collected non-invasively using simple equipment. This paper explores how salivary components can be used as diagnostic tool to identify chronic kidney disease (CKD). Experimental analysis was conducted to assess the levels of salivary components in whole saliva of CKD patients in contrast with healthy people. Urea and creatinine are the most accepted biomarkers of CKD. The correlation between creatinine and urea levels in human saliva and blood were analysed. Unstimulated saliva flow rate and pH levels were also monitored in this study. The results obtained from this study give concrete evidence that there is a positive correlation between creatinine and urea levels in blood and saliva. From the derived regression line equations, serum urea and creatinine values can be predicted from salivary values. Receiver operating characteristics (ROC) performance analysis was performed and area under the curve (AUC) of 0.95 and 0.89 was obtained for salivary creatinine and urea.

by J. Saraswathy, M. Hariharan, Wan Khairunizam, J. Sarojini, Sazali Yaacob
Abstract: This paper proposes a new investigation of time-frequency (t-f) based signal processing technique using wavelet packet spectrum (wpspectrum) for classification of newborn cry signals. T-f approaches can analyze the non stationary signals comprehensively in joint t-f domain compared to the time or frequency domain techniques. This study was initialized with the extraction of a cluster of t-f features from the generated t-f matrix of recorded cry signals using wpspectrum by extending time-domain and frequency-domain features to the joint (t-f) domain. In accordance, conventional features such as Mel-frequency cepstral coefficients (MFCCs) and Linear prediction coefficients (LPCs) were also extracted in order to compare the performance of the suggested t-f approach. Probabilistic neural network (PNN) and general regression neural network (GRNN) were used to evaluate the efficacy of the extracted feature vectors. The proposed methodology was implemented to classify different sets of infant cry signals cry including binary and multiclass problems. Best empirical result of above 99 % was reported and revealed the good potential of t-f methods in context of infant cry classification.

Improving ECG Signal Denoising using Wavelet Transform for the Prediction of Malignant Arrhythmias
by Agostino Giorgio, Cataldo Guaragnella, Domenico Andrea Giliberti
Abstract: Objective: This paper deals with the accuracy of algorithms for the detection of cardiac Ventricular Late Potentials (VLP). The presence of VLP in an electrocardiographic signal (ECG) is associated with possible sudden cardiac death, because of malignant arrhythmias. VLP detection is strongly influenced by signal noise, thus the ECG needs to be denoised before VLP detection. The objective of this paper is to define a denoising algorithm improving the VLPs detection in ECG signal, and to describe its hardware implementation on a Field Programmable Gate Array device (FPGA). Methods: The method described uses wavelet denoising, implemented as subband coding. The drawbacks of this method are heavy linear distortions undergone by the analyzed signal. This disadvantage is overcome by using an equalization filter properly designed by the authors for canceling the introduced distortions. Results: The algorithm (equalizer filter + wavelet denoising) has been firstly implemented and successfully verified using MATLAB. Then, it has been implemented as programmable hardware on Alteras FPGA. The synthesized hardware has been verified on the evaluation board DE1-SoC, mounting a Cyclone V 5CSEMA5F31C6 FPGA chip. Conclusions: On board processed results and theoretical results are consistent, validating the effectiveness of the algorithm and of the designed hardware. Significance: Results show that the algorithm accuracy and its capability to be implemented as programmable hardware also could be used for upgrading ECG devices reliability in the field of heart diseases prevention.

A REVIEW ON AUTOMATIC IDENTIFICATION OF FOVEA IN RETINAL FUNDUS IMAGES
by Rajesh I S, Bharathi M A, Bharati M. Reshmi
Abstract: Identification of retinal diseases is a very significant area of ophthalmology. Regular procedures are extremely specific, which rely on manual observation and highly prone to error. Hence, it is extremely fundamental to set up an automatic system for screening of vision-threatening diseases like Diabetic Retinopathy (DR) and Diabetic Maculopathy (DM). Patients who are suffering from DR are at high risk to have DM which may lead to blindness, if not detected and treated appropriately at the appropriate time. Automatic analysis of retinal images requires knowledge and the properties of anatomical structures and retinal lesions. Thus, locating fovea plays a vital role in the analysis of retinal images. In recent times image processing has become a very effective tool for the detection and analysis of abnormalities in retinal images. This survey paper depicts the fundamental terminology related to automatic detection of macula and fovea. The literature review of various methods used for finding fovea in retinal fundus images is discussed. Detection issues involved in fovea are also discussed in this paper.

Enhancement and segmentation of histopathological images of cancer using dynamic stochastic resonance
by Anuranjeeta Anuranjeeta, Munendra Singh, K.K. Shukla, Neeraj Sharma, Shiru Sharma
Abstract: Pathologists face difficulty in cell image detection as uneven dye causes the low contrast and inhomogeneity. The proposed Discrete Cosine Transform (DCT) based Dynamic Stochastic Resonance (DSR) technique enhances the histopathological images of cancer. Further, the DSR based Otsus thresholding processed image helps in the better segmentation of histopathological images of four types of cancer cells, i.e. breast, cervix, ovarian and prostate cancer. The comparison of segmentation results were performed on the University of California, Santabarbara (UCSB) available breast cancer datasets for analysis. The algorithm has been applied to total twenty-two (22) breast cancer images including benign and malignant and compared with Region of Interest (ROI) segmented Ground Truth images to validate the performance of proposed DSR based Otsus thresholding. DSR based Otsus segmentation obtained better results with 0.776 average correlation, 0.979 average normalized probabilistic rand (NPR) index, 0.011 average global consistency error (GCE), and 0.185 average variation of information (VI). These indices are higher than the other conventional segmentation methods and have the advantage to identify the target objects in low contrast images.

A Semantic Interoperability Framework for Distributed Electronic Health Record Based on Fuzzy Ontology
by Mohammed Elmogy, Ebtsam Adel, Shaker El-Sappagh, Sherif Barakat
Abstract: To achieve an efficient healthcare process; the professionals and doctors need to access the complete data about their patients in the suitable time. In the face of that issue; the medical data by natural is distributed across different systems and heterogeneous sources. From another angle; Healthcare semantic interoperability is still a huge problem without solving. In this paper, a unified semantic interoperability framework for distributed EHR based on fuzzy ontology is proposed. It consists of three main layers. The lowest layer (local ontologies construction) stores the EHRs heterogeneous data with different database schemas, standards, terminologies, purposes, locations, and formats. In the middle layer (global ontology construction) the local ontologies are mapped (using mapping algorithms or human experts with the help of common terminology vocabularies) to a global crisp one. The global reference ontology combines and integrates all local ontologies and therefore describes all data. Finally, the third layer is the user interface, in which a doctor can ask any linguistic or semantic queries by dealing with only the global reference fuzzy ontology. We expect that our framework will handle the current EHR semantic interoperability challenges, reduce the cost of the integration process, and get a higher acceptance and accuracy rate than previous studies.

Modified Model for Cancer Treatment
by Mahdi Rezapour Shafigh
Abstract: This paper proposes an optimal method for eradicating cancer, such that it cannot be relapsed. The major issue is that from the dynamical point of view, the tumor free equilibrium point at the end of chemotherapy is still unstable. Mathematically it means that when the chemotherapy is stoped, the dynamic behavior of the system moves away from the tumor free equilibrium point and the tumor cells starts increasing. To overcome this problem, we can either restart the process of chemotherapy or we try to stabilize the equilibrium point. In this paper the stabilization of the equilibrium point is proposed by applying a combination of vaccine therapy and chemotherapy method. According to this method, the vaccine therapy changes the dynamics of the system around the tumor free equilibrium point, and the chemotherapy pushes the system to the domain of attraction of the desired point. A suboptimal control strategy based on the State Dependent Riccati Equation (SDRE) is used for the chemotherapy process in this nonlinear cancer model. According to this method it is possible to study the particular conditions of an individual patient by choosing proper weighting matrices in the cost functions and limiting the dose of chemotherapy drug. It is shown, that, according to the simulation results, after completing the chemotherapy process, the dynamic of the system becomes stable and the cancerous cells converges to zero.

by Sofia Bobby
Abstract: slowing down of thought, memory and thinking is a normal part of aging. Mental exercise can help the brain to stay sharp. The EEG signal was acquired using single channel electrode from the occipital lobe, amplified using EEG amplifier and connected to the system through Data Acquisition Device (DAQ). The peak alpha band (10-11Hz) signal was extracted using LabVIEW software. The NFT protocol that was designed presented the neurofeedback training and thereby showed some improvement in their cognitive processing speed. The brain wave frequency was measured and analyzed in the course of training and the subject gradually learnt to stay in the desired brain wave state. The visual cues were fed to the LabVIEW software by making the subject visualize some animation or hear some audios. Twenty subjects aged between 60 and 65 were considered for this training. This study had investigated whether the training given to the elderly people showed improvement in the cognitive processing speed of their brain activity.

A Frugal and Innovative Telemedicine Approach for Rural India- Automated Doctor Machine
by Aswath G.I., Shriram KV, Nalini Sampath
Abstract: Rural India is very poor [Disconnected] when compared to urban. Most of the developments have not yet reached rural India and most importantly, in Healthcare, it lacks good hospitals and sometimes they even don't have a good dispensary. Even when there are hospitals, rural people never get experienced Doctors. We know that rural people are more affected by many challenging diseases every year. To compensate all these problems and to provide a good health care even in rural villages we introduce an Automated Doctor Machine. This machine can be installed easily anywhere and also include all the required input sensors inbuilt to check the condition of the patient and also provide a diagnosis report with medicines. The patient's health report is updated to the health record in his cloud account once he receives the medicine. So, when he meets the doctor in future, the doctor can easily get his up to date health record and can also use the web app to update his health record. This is all frugal, cost-effective and fault tolerant.

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.

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.

Abstract: Bone tumors could be benign or malignant, and primary or metastatic due to systemic cancer cells dissemination. They destroy bone and lead to pathologic fractures. The main objective of this work is to study the thermal effect induced by the bone cement polymerization, in the bone metastatic tumor minimization and to understand the role of such procedure in bone tumor necrosis due to thermal effects and its biomechanical stabilization for this function. To assess the clinical effect, it is important to simulate and test this methodology before its application and obtain sustained results. In this work, a numerical model was developed to predict the temperature distribution produced by cement polymerization, and due to the thermal necrosis effect the metastatic tumor area minimization is verified. Different numerical simulations were produced for different cement sizes introduced in a cortical and spongy bone tumor, with or without an intramedullary nail in titanium. The numerical models were built according to average dimensions of patients obtained from digital conventional radiographs. For each model, the temperature distribution due to the cement polymerizing effect is represented, which affects thermal necrosis and the amount of bone cells penetration. The finite element results obtained from numerical simulations allow to conclude about the high temperature spread effect in bone material. In conclusion, values greater than 45

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 Fernandes, Elza Fonseca, Renato Natal Jorge, Maria 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 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
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 optimize the indexing of graph nodes in ontological database and many evolutionary and particle of swarm optimization (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 optimization 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 Vinothkanna Rajendran, Prabakaran Narayanaswamy, Sivakannan Sivakannan
Abstract: To solve the issue of close human contact in biometric authentication system, relatively a new technique gait recognition is used. The human gait is a common feature for identifying the walking manner of the person during walking and it is viewed as significant indicator for gait function of individual for experimental and research setting. Gait symmetry is usually considered as function of locomotion between the changes of the body and its activities. An exclusive advantage of gait as a biometric is its latent for detection at a distance or at low resolution or when other biometrics might not be perceivable. In this paper we investigate the problem of people recognition by their gait. The coordination and cyclic nature of the body motion makes gait as unique characteristics of each individual, thus a good biometric identification approach. The purpose of this paper is to describe some of the problems that make it difficult to apply gait as a biometric identification and use recent literature to show suggestions being made to solve some of these technical issues.

by Smita Jhajharia
Abstract: Machine learning techniques for cancer prognosis are being widely researched and applied. Supervised learning in conjunction with other computational techniques are paving the way forward for predictive health analytics. The step of input feature processing is very important in order to obtain meaningful results from a data analytics problem. In this paper, the Extended Kalman Filter (EKF) and Fuzzy K-Means clustering algorithms have been combined and a hybrid algorithm is proposed with improved functionality compared to either of the two separately. The proposed hybrid algorithm implements a fuzzy K-means algorithm with Support Vector Machine (SVM)coupled with an EKF for data filtering. From the filtering and prediction consecutive cycles, the result of Kalman filters is obtained and fuzzy membership functions are calculated in order to form a relationship between the labels and attributes. K-means utilizes this relationship to create a new modified set of attributes, which are given to the SVM classifier, with lesser number of support vectors. The number of clusters is added into the training process as the input parameter except the kernel parameters and the SVM penalty factor. The approach was tested for various publicly available data sets like UCL,SEER and a real data set compiled by the authors. After performing statistical analysis, the accuracy, precision, recall and F-score value of the algorithm have been found and compared against those obtained from the traditional algorithms.
