Towards this end, we use signal processing (SP) features such as energy, differential entropy, geometric power and p-norm. For the classification problem of SS, we employ deep neural network (NN) architectures such as multi-layer perceptron (MLP), convolutional NN, fully convolutional network, residual NN (ResNet), long short-term memory and temporal convolutional network. Through extensive experiments based on real-world captured datasets and Monte Carlo simulations, we show that MLP and ResNet architectures offer the best performance in terms of probability of detection, for a given predefined level of probability of false-alarm. Further, we show that NN architectures trained with a combined set of the SP features yield the best performance.","PeriodicalId":413789,"journal":{"name":"2021 IEEE International Conference on Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125914110","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}

It alleviates the performance degradation observed in the present CMOS circuits which are built using standard von-Neumann architecture. However STT-MTJ suffers the issues such as switching delay due to stochasticity as well as wastage of write power. Hence, in this work continuous monitoring and self-write-termination (SWT) process is adopted for STT-MTJs and studied the performance of all the logic gates; AND/NAND, OR/NOR and XOR/XNOR developed using LIM architecture. Investigation of the read/write power, read/write delay, read/write power delay product and transistor count of SWT-STT-MTJ/CMOS logic gates are performed and compared them with its conventional counterparts. Further, Monte-Carlo simulations are also conducted to study the behavior of hybrid logic gates for variations that could occur during fabrication. The simulation results reveal that SWT-STT-MTJ/CMOS logic gates dissipates lower power, PDP and produce quicker output response.","PeriodicalId":413789,"journal":{"name":"2021 IEEE International Conference on Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115049574","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}

Magnetoencephalography (MEG) is a widely used neuroimaging strategy to understand the pathology and the therapeutic effects of DBS in clinical cohorts. One of the significant limitations is the inability to differentiate the DBS stimulation artefact from actual neuronal excitations, especially in lower frequency bands of interest where sub-harmonics of DBS artefacts may obscure the biological response and is a confounder. The primary objective of this study is to understand how DBS stimulation artefacts affect MEG signals and to this end, we employ a phantom based on a water melon. Using this phantom, we record the spectral signature of the DBS stimulation artefact at various DBS frequencies and stimulation voltages, the effect of standard artefact rejection approaches like spatiotemporal signal space separation (tSSS).

However, when we are speaking about any classroom the attendance system still remains primitive. The traditional attendance system where the teacher/lecturer calls the name of students to mark their attendance in an attendance register is a manual method which is found to be not suitable for a smart class due to a list of disadvantages. The automatic attendance management will replace the manual method. This dynamic attendance management system will consider the physiological features of the human beings for uniquely identifying them. Hence we are using a biometric based attendance system. There are many biometric processes, among which face recognition is the best method. In the proposed project, we are going to describe the attendance without human interference. In this method a camera, fixed within the classroom will capture the image, the faces are detected and then they are compared with the faces in the database and finally the attendance is marked. It also proposes a single image-based face liveness detection method for discriminating 2-D paper masks from the live faces. Freely available machine learning and deep learning tools like dlib, Keras are used for making the face recognition faster and accurate one. This makes the system suitable in a real life scenario.","PeriodicalId":413789,"journal":{"name":"2021 IEEE International Conference on Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126693648","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}
