These devices were successfully extended to the field of human neuro therapy. Many different electrodes exist. However, no quantitative ranking criterion is available to allow meaningful comparison of the various DBS electrodes to aid the designer.This paper presents a novel Figure of Merit (FOM) dedicated to DBS electrodes. The proposed optimization performance takes into account safety factors of mechanical analysis and the estimated fabrication cost of some materials. The FOM is used to rank several DBS electrode designs.Finite Element Models (FEM) analysis for several electrode layouts are conducted. FEM shows the effects of different design parameters on the electrode mechanical performance. These parameters include electrode dimensions, geometry, and materials. The electrodes mechanical analysis is evaluated from different points of view including: linear buckling analysis, stationary analysis with axial and shear loading. The safety factors are calculated for several designs with different materials (brittle and ductile materials). The results obtained from FEM mechanical analysis for the various electrodes prototypes are presented, which provide guidelines for different electrode designs and material choice. A proposed fabrication process along with an estimated fabrication cost is also introduced.","PeriodicalId":243968,"journal":{"name":"2020 32nd International Conference on Microelectronics (ICM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129240757","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}

While a compact model for VCSEL already exists, it does not sufficiently describe the behavior of tunable VCSELs. This paper discusses the creation of a compact model for HCG MEMS-tunable VCSELs implemented in Verilog-A using semiconductor laser rate equations.

Previous research papers were published exploring the possible techniques to utilize the EEG signals for detecting and predicting seizure onsets through Machine Learning and Deep Learning models, such as Support Vector Machines and Convolutional Neural Networks. The aim of this work is to build practical hardware-implementable Machine Learning classifiers capable of predicting the seizure onsets prior to their occurrences with high sensitivity and accuracy. The classification method proposed involves removing certain channels for each patient, extracting the features from the EEG signal, selecting the best feature combination for each patient, and finally training the selected SVM classifier accordingly. Evaluating the performance of the proposed classification technique yields promising results for the selected patients with accuracies exceeding 95%.","PeriodicalId":243968,"journal":{"name":"2020 32nd International Conference on Microelectronics (ICM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130528759","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 proposed architecture optimizes efficiency with the presence of different forward voltage drop across each WLED connected in series in one string and among different strings. The strings don’t even need to be balanced (could have different numbers of WLEDs per string). The efficiency optimization is done via setting the minimum proper voltage (in real-time) at the output of the boost converter that activates all parallel strings and by choosing the appropriate arrangement of strings (number of strings and number of WLEDs in each string). Each string has a constant regulated current of 25 mA to drive the series-connected WLEDs in that string. An efficiency of 88.85 % was achieved with input voltage ranges between 3 V to 3.8 V and output voltage up to 25 V .

The idea behind this work is development of a computational model for the study of the impact of different ventilation modes on patient’s respiratory system generally, and lungs more specifically. This model has been created using Matlab/Simulink platform. The studied ventilation mode is the Pressure Controlled Ventilator (PCV) signal combined to single and two compartmental models in series and in parallel mathematical models configuration of the lungs that represent the respiratory system parameters for testing. The ventilator’s setup includes the following parameters: positive end-expiratory pressure (PEEP), pressure wave, respiratory rate (RR), tidal volume, and others. By changing one of these parameters, we can monitor how this will affect the lungs by checking the volume, flow and PV loop for each lung mode. Simulation results have been recorded and are promising because this allows to study any type of ventilation modes conventional or novel ones virtually without the need to jeopardize the life of human subjects during clinical trials.","PeriodicalId":243968,"journal":{"name":"2020 32nd International Conference on Microelectronics (ICM)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117167890","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 first feedback mechanism is an analog regulation that includes an error amplifier. The second feedback mechanism is based on digitizing any fast change in the output voltage using multiple comparators and subsequently enabling either an NMOS based or a PMOS based current DAC. The DAC provides current in opposite polarity to the sharp transient change in load current. As a result, sharp changes in load current is addressed by high-speed current DACs and is not limited by the performance of the error amplifier. The LDO was implemented using 180nm CMOS technology devices. It uses a supply voltage input range of 1.6 V – 2.0 V and produces an output voltage of 1.2 V. In simulations, the LDO regulator achieves 188 uA quiescent current, -56 dB PSRR @ 1 KHz noise frequency and an output voltage drop of around 200 mV for a load current step of 100 mA.","PeriodicalId":243968,"journal":{"name":"2020 32nd International Conference on Microelectronics (ICM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129097899","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}

This kind of information is very attractive to attackers for real position exposure of nodes making the whole network vulnerable to different kinds of attacks. According to WSNs privacy, there are two types of threats affect the network: Contextual and Content privacy. In this work, we study contextual privacy, where an eavesdropper tries to find the location of the source or sink node. We propose a Multi-Sinks Cluster-Based Location Privacy Protection (MSCLP) scheme in WSNs that divides the WSN into clusters, each cluster managed by one cluster head (CH). Each CH sends random fake packets in a loop then sends the real packet to the neighbor’s CHs using a dynamic routing method to confuse the attacker from tracing back the real packet to reveal the actual location of the source node, we are taking in our consideration two important metrics: the energy consumption, and the delay.","PeriodicalId":243968,"journal":{"name":"2020 32nd International Conference on Microelectronics (ICM)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121584364","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}
