We have developed a finite element model of rigid nanoneedle. This nanoneedle is able to penetrate a cell wall and measure a cell wall's stiffness. W303 yeast cell has been selected as a cell model and a Tungsten metal has been used to model the nanoneedle. ABAQUS 6.10 CAE/CFD by Dassault Systemes, a powerful finite element (FE) tool has been used to perform the numerical analysis. Nonlinear Mooney-Rivlin hyperelastic material has been used to develop the cell model. The parameters of yeast cell have been obtained from the previous experimental on the mechanical properties of yeast cell such as: cell diameter (3-6 μm), area, Young's modulus, Poisson's ratio and membrane failure analysis. After analyzing the parameters numerically, we have obtained single yeast cell penetration force which is 397 nN. This penetration force indicates the yeast cell wall's stiffness. This method might be used for measuring any kind of cell wall stiffness.","PeriodicalId":177199,"journal":{"name":"2012 IEEE-EMBS Conference on Biomedical Engineering and Sciences","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128607472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both at hospitals and homes, radio waves are always present in our daily lives in the form of signals transmitted from TV, Radio and Mobile base stations. There are many signals of different frequencies in our surroundings that can be reclaimed via a harvester. Even though these signals carry a small amount of energy, the possibility of using that to energize devices is promising. The methodology of this work is to analyze the RF energy spectrum to identify the most available RF energy sources. Based on that we design an appropriate antenna to capture that spectral power and replicate a circuit that can convert micro-scale RF energy received via the antenna into usable electrical power. Finally, the harvester circuit is used to feed power to a table clock and successfully demonstrated. The limitations are noted along with how the system may be improved through better antenna design. This harvester design is unique in not using a battery.","PeriodicalId":177199,"journal":{"name":"2012 IEEE-EMBS Conference on Biomedical Engineering and Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127010167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The staging of the disease is often based on 2-dimensional (2D) slices from tissue samples stained with hematoxylin and eosin. Therefore, much of the 3-dimensional (3D) structure of the carcinoma is unknown. We develop a method for producing 3D reconstructions of DCIS specimens from serial sections. This includes an alignment, duct segmentation, cribra segmentation and 3D reconstruction method. Our results show that there are different 3D architectures of cribriform DCIS classified by 2D histological slices. We conclude that the 3D morphology of the disease is complex and may provide additional clinical information than the classical 2D approach.","PeriodicalId":177199,"journal":{"name":"2012 IEEE-EMBS Conference on Biomedical Engineering and Sciences","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114372177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The elastic properties of agar based phantom are imaged using Ultrasound Elastography. The computer modelling and linear strain analysis of the phantom are done using finite element method. The visual display of strain results are compared with the experimental results and they are in good agreement. This allows us to model many hypothetical structures of real life and will be useful while validating signal processing algorithms for new imaging modalities.","PeriodicalId":177199,"journal":{"name":"2012 IEEE-EMBS Conference on Biomedical Engineering and Sciences","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133929708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Memory is an important part of brain that controls and processes our present and past information and interconnects with future plans to assist corresponding dynamic activities of whole body. In cognitive psychology, human memory processes are functionally divided into three categories namely encoding, retention, and recalling. This paper provides an overview of memory processes and brain regions that are activated during these processes using electroencephalography (EEG) and functional magnetic resonance imaging (fMRI).

However, in many cases it is difficult for doctors to distinguish obscure gastrointestinal bleeding of patients; moreover, the diagnosis process of the obtained video could take long time due to the huge number of generated frames. This project provides a method to automatically detect bleeding areas in the WCE images by using Support Vector Machine (SVM) classifier as the main engine with learning based mechanism in order to increase the accuracy. The experiment results show that this could not only advance the accuracy of WCE diagnosis, but also reduce the diagnosis time effectively.
