The controller parameters are designed using the Astrom-Hagglund (AH) tuning technique. The order of integrator and differentiator stages are obtained by using the Neider-Mead (NM) optimization technique. The circuit is realized using a single active element and RC network. The controller performance parameters are evaluated using the LTspice simulator for TSMC 0.35 μm CMOS process.","PeriodicalId":131517,"journal":{"name":"2020 IEEE International Conference on Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130031858","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 approach helps to quickly learn the fundamental concepts of science and engineering through virtual experimentation, fosters curiosity and innovation among students, and prevents laboratory hazards. In this paper, we describe the design and development of two web-based virtual laboratories that simulate the fundamental concepts of Civil Engineering and Environmental Engineering. The proposed virtual labs provide a detailed explanation of the experiments in the respective engineering domains, and reagents and apparatuses involved while performing the experiments.

Online modes for classroom teaching can only be afforded if all our students have access to smart devices and internet facilities. We assess different features of the current state of affairs in government-run schools. Based upon evaluations, a low-cost Raspberry Pi 4 based mini intellectual system has been designed to facilitate online lecture delivery. The proposed system is an ideal low cost and energy-efficient solution to be provided to the students.

Electroencephalogram (EEG) readings which capture the signals that are transmitted between the neurons across various parts of the brain can help in diagnosing Epileptic seizures which is different from normal controls due to topological, structural, and network changes. Features like Approximate Entropy and Kolmogorov Complexity are extracted from the readings captured by EEG electrodes. These readings act as inputs to the five-layered Back Propagation Multi-Layer Perceptron Neural Network in performing training and testing in order to classify the patients suffering from Epilepsy and normal controls. Initially, this methodology is applied to readings from all the 14 electrodes that are available from the database resulting in Accuracy of 96.5 %, Precision of 98.1 %, Sensitivity of 95%, and Specificity of 98% with Area Under the Curve (AUC) of 0.964. Since the data from 14 electrodes consume a lot of storage space and time for calculation and analysis, the subsets of EEG electrodes F7, F8, FC5, FC6, T7, T8 which are placed over the temporal region of the brain which is mainly affected during seizures is considered and when the same methodology is applied on it, results in Accuracy of 97 %, Precision of 95.5 %, Sensitivity of 99 %, and Specificity of 94.5 % with AUC 0.967. In both the cases, their classification performance is almost equal but the storage space and the time taken for calculation in the second case are comparatively lesser than the first case due to less number of EEG electrodes involved. This can help in the faster diagnosis of Epilepsy in patients.","PeriodicalId":131517,"journal":{"name":"2020 IEEE International Conference on Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"248 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124727224","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}

In order to diagnose AF, Electrocardiogram (ECG) is used in correlation with clinical symptoms. ECG is noninvasive and cost effective modality in order to diagnose cardiac abnormalities using AF. The complexity of ECG and its interrelationship with other physiological parameters make the AF detection a challenging task in the clinical practice. The traditional practice of diagnosing AF manually by the physician can cause intra physician variability leading to a need for automated algorithm based assisting system to detect AF. In the present methodology, the QRS complex is detected and each beat in the entire signal is segmented, the median beat is calculated for a given signal, the dimensionality is reduced using Principal Component Analysis (PCA) and the resultant components along with energy values are used for classification using decision tree. The methodology provided an improved average accuracy of 85.1 percent which is reasonably high. The system developed can be used in many practical applications and can provide acceptable results in clinical implementations. The developed methodology can be used as an adjunct tool by the physician in his clinical practice.","PeriodicalId":131517,"journal":{"name":"2020 IEEE International Conference on Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130596779","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}

Data randomization is carried out in this technique that renders the leaked data useless in the event of a Trojan attack. The percentage of randomization and recovery obtained is taken into consideration to assess the design efficacy. Design analysis on combinational circuits for a given set of inputs provided randomization of 50% and efficient data recovery. The design study of the RECORD method when extended to sequential circuits provides randomization of 40% and 100% recovery for an appropriate sequence of random bit change at every clock cycle.","PeriodicalId":131517,"journal":{"name":"2020 IEEE International Conference on Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131053758","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}

Networks are formed by the random deployment of nodes in the required fields, which are usually anisotropic. Locations of the deployed nodes are essential to act on the collected data. To estimate the locations of nodes in the network, a number of localization algorithms are developed which make use of techniques such as hop distances and centroid to estimate the positions of nodes. These algorithms showed sub-optimal results when tested in anisotropic fields with obstructions. In this work, a priority based localization algorithm is reported, which gives priority to a few reference nodes based on their Average Hop Distances (AHD). Nodes are then localized with weighted centroid method using high priority reference nodes. The simulation results show that the localization results of the reported algorithm is better than the existing weighted centroid methods in anisotropic fields.","PeriodicalId":131517,"journal":{"name":"2020 IEEE International Conference on Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133988412","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}
