It is known that the improved energy detector (IED)- which calculates the sample norm of an optimally chosen order in the received observations - outperforms the conventional energy detector (ED). The relatively recently proposed joint correlation and energy detector (CED) combines the sample energy and the first order correlation values in the received observations, and it is known that when the combining is carried out optimally, it outperforms ED. We present a comparative performance study of CED and IED, for different incumbent signal models, following the Neyman-Pearson framework. We show that the CED consistently outperforms IED across the Gaussian, sinusoidal and constant signal models. Similar to what was reported earlier, the IED is observed to outperform ED only for low values of probability of false-alarm. Hence, this study establishes the applicability of CED for spectrum sensing, as opposed to IED and ED.","PeriodicalId":274260,"journal":{"name":"2019 IEEE International Conference on Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122287219","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}

Working on the similar goal, this paper proposed a methodology to enhance end to end performance of the system. The proposed method utilizes the Principal Component Analysis (PCA) for data reduction, MIMO channel combination with 4-PSK modulation having Low Density Parity Check (LDPC) error correction. The BER and RMSE is calculated for both the schemes and the performance of the system is evaluated with the different configuration of the 2x2,3x3,4x4 MIMO channel with and without LDPC. This paper demonstrated the sensor data reduction with PCA to transmit the extracted features of the data over MIMO AWGN channel over LDPC correction to regress the data at the receiver end. The performance of the system is studied for Bit Errors Rate over noisy channel and RMSE to confirm the signal regression.","PeriodicalId":274260,"journal":{"name":"2019 IEEE International Conference on Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130442534","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 system helps reduce risk involved in agriculture, allows digitization of agriculture, cuts down on mediators thriving in the market and thereby allows farmers to have better agricultural yields and earn a higher margin of profit. The proposed system shall also be of great monetary benefit to the government as they shall be able to deal directly with the farmers in matters of funding and investment in the field of agriculture. In addition to the current updated market rate of crops being displayed over the Android application for easy reference, future market rates based on the demand, supply, base price and season time of each crop, has also been predicted using W D Gann's Prediction and Pattern Matching algorithm that shall be of great help to the buyer, in this case the administrator. This shall help the farmers understand planting which crop shall yield the maximum return depending upon the present agricultural scenario, participate in cashless transactions with the government administrator for direct selling of crops and also be updated about modern tools and farming techniques that are shared and suggested by the educated sector of our society via YouTube links etc. So automating the entire process of agriculture is beneficial for both, the farmers and the government in the long run.","PeriodicalId":274260,"journal":{"name":"2019 IEEE International Conference on Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122217088","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}

Most of the casualties from accidents are due to poor communication to the concerned agencies and late arrival of medical assistance. Nowadays there are many technologies like Anti Collision System (ACS), Antilock Braking System (ABS), and Adaptive Cruise Control (ACC) that helps to prevent accidents. However, even after this the number of casualties from accidents is on the rise. Our paper aims at providing a solution to this problem by providing quick and proper communication to the concerned personnel so that proper medical help can arrive quickly to the accident location. With Arduino Uno as the brain of the device, it uses an accelerometer to detect the accident, a heart rate sensor for monitoring the heart rate of the driver, a GPS module to detect the location of the accident and a GSM module to send an SMS to the nearest hospital, nearest police station and a relative of the concerned driver with a google maps link to the location and heart rate of the driver. This will ensure the quickest arrival of medical assistance giving the victim the better chance of survival.","PeriodicalId":274260,"journal":{"name":"2019 IEEE International Conference on Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127890007","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}

Machine detecting these concealed information of emotion is important for emotional intelligence. It has wide applications in healthcare, aviation and defence. Statistical measures (central tendency of mean measure of spread) of autocorrelated pitch are used as features for analysing the progression of concealed emotion. The analysis of concealed emotion is performed over the synthesised concealed emotional speech signal. This speech signal is synthesised using the standard emotional speech signals (anger and neutral) from Berlin Emotional Speech (BES) database. T- statistic likelihood is used as measure for analysis of concealed emotion progressing over the synthesised speech signal. This framework is shown to provide a good tracking of emotional progressions over the synthesised concealed emotional speech signal.","PeriodicalId":274260,"journal":{"name":"2019 IEEE International Conference on Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134212683","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 has always been a good mode for understanding a problem and subsequently analyzing the solution. A graph data structure is a good choice to represent data if it can be converted in the form of nodes and edges. There are different types of problems in various elds which require a graphical method to understand the problem, and so there are several approaches for doing it. On similar lines, this paper proposes a new visualization technique for a dense graph. It is evident that existing visualization techniques, such as force-directed placement would not give optimal results for a dense graph. The proposed work is interesting and has several potential applications such as in analyzing graphs for Social Networks, Biological applications, etc. There are many graph layout techniques available, and it has been studied for years. Every year some new method is proposed, or an older one is improved. This is because of the exponentially increasing data, which requires a better layout technique for representation. Today, graph is used in different research areas due to its simplicity in the way of representing the information. A graphical representation is always good for understanding the information easily. When these graphs become dense, the overlapping of edges in the graph also increases by a certain amount, and it becomes difcult to understand the graph or tough to visualize the graph. For a better understanding of dense graph, this paper proposes a solution by dividing the original graph into sub-graphs forming cliques. These cliques are then aligned in special positions to overcome the confusion between the connectivity of nodes. This idea considerably solves the visualization problem with dense networks, and the results show a better visual representation","PeriodicalId":274260,"journal":{"name":"2019 IEEE International Conference on Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129733253","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}
