Simulation will be done in arduino platform and net connectivity will be done through GSM module interfacing. The work was inspired by the idea of the approach on Internet of things and to develop a solution to minimize the excessive power usage and thereby minimizing the power consumption cost. Solution is been proposed for monitoring the power utilization. The solution can be collaborated in transmission of any sensor data. Currently, in this implementation, dynamic data is being received by Arduino from a delphino DSP, and GSM module is used as the gateway to transmit the data into cloud storage. This data in cloud storage is been analysed using user interfaces and thus excessive power consumption can be monitored. Brief overview of the proposed solution at the stage of communication is also discussed.","PeriodicalId":383554,"journal":{"name":"2016 IEEE Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128479671","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 PLL operates over a supply voltage range of 1.3V-1.8V, generating locking frequencies in the range 500 MHz to 1.5 GHz. The proposed charge pump limits the variation in charging and discharging currents to 0.03% of its biasing value, which is designed to be 34.7uA, for change in control voltage from 0.4 V to 1.1 V. Power consumption of the PLL is limited to 2.3mW at 1.8V supply voltage and reduces to 0.9mW for a supply voltage of 1.3V. A 10bit successive approximation register analog to digital converter (SAR ADC) is operated using the proposed PLL and the effect of variation in frequency on its output is demonstrated.","PeriodicalId":383554,"journal":{"name":"2016 IEEE Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127210161","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 attitude motions are produced due to deflections of the flaps, in the slip stream of the propeller induced airflow. A coordinate-free (geometric) control law is developed to eliminate configurational singularities in control design, thereby enhancing the agility of the drone. The control law is directly on the nonlinear manifold, i.e., SO(3), without any Euclidean parametrization. A dynamic compensator is incorporated into the geometric control law; this enables the system to adapt to the uncertain parameters while achieving the original control objective. Simulations of the proposed control law are presented and discussed.","PeriodicalId":383554,"journal":{"name":"2016 IEEE Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115169237","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}

Structure prediction algorithms generally operate by computationally generating a large number of protein structures known as decoys and selecting the best candidates from among them. This is done by clustering the decoy set to identify the best models. RMSD (Root Mean Square Deviation) is the metric used for measuring similarity between protein structures. As the number of decoys becomes larger, the huge computational time of RMSD calculation affects the overall performance. This paper is about the performance analysis done on clustering techniques of SPICKER, Calibur and Hierarchical Ward's clustering and also describes 2 methods for parallelizing RMSD computation.","PeriodicalId":383554,"journal":{"name":"2016 IEEE Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115420660","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}

Various research works are going on designing of logic circuits, digital memory and neuromorphic systems using this nano device. Both pure and hybrid approaches are followed for the design purpose. Material implication logic brings in the motivation for exploring memristors in the area of logic design. In this work material implication logic has been applied to design complex combinational circuits like demultiplexer, encoder, priority encoder, decoder and magnitude comparator using memristors. Both serial and parallel approaches have been used for the design purpose and the parallel implementations require lesser step counts than their serial counterparts. Also the designs presented occupy lesser area than their conventional CMOS-peers.","PeriodicalId":383554,"journal":{"name":"2016 IEEE Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"161 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123503580","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 paper discusses how to represent the mesh current and node voltage equations in matrix form by direct matrix manipulation for the circuits containing independent and dependent, voltage and current sources. A correction matrix with two stage corrections is proposed in which the first stage correction considers the effect of ideal current (voltage) sources for mesh (node) analysis. This stage mainly deals how to handle the constraints due to internal current sources (floating voltage sources) which may be independent or dependent. In the second stage, the controlled variable of the dependent sources is expressed in terms of the mesh currents (node voltages), so the value of matrix elements changes to accommodate the effect of dependent sources.","PeriodicalId":383554,"journal":{"name":"2016 IEEE Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125404320","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}

For moving users the channel coefficients vary with time and, therefore, it is required to update CSI both at the transmitter and receiver at regular intervals. Meanwhile it is important to note that frequent updates of CSI will reduce data rate and delayed updates will cause a large variation in CSI. In this context we explore the error performance of IA in two-user multiple-input multiple-output (MIMO) X channel where the channel suffers continuous time-varying fading. The bit error rate (BER) performance of MIMO two-user X channel is evaluated for different Doppler frequencies. We also propose a method for calculating optimal pilot overhead for time-varying channels by setting an upper bound on BER.","PeriodicalId":383554,"journal":{"name":"2016 IEEE Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127022534","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 implementations currently employed are based on Serial execution on General Purpose Processors. But the high cost and complexity of such implementations doesn't make it a viable option for real time surveillance system. The system proposed here is implemented on Field Programmable Gate Arrays (FPGA) Zynq XC7Z020 board using Modified Background Subtraction algorithm for real-time Object Detection and Tracking. The presence of numerous configurable logic blocks, distributed memory and hard Digital Signal Processing (DSP) modules offers a great flexibility in achieving Temporal and Spatial parallelism. This paper uses Xilinx ISE software for implementation which is programmed in VHDL. OV7670 camera used in the paper has a resolution of 0.3 Megapixel and it captures the video at a speed of 30fps. The reference frame and the subsequent incoming frames are stored in different memory modules before the Modified Background Subtraction algorithm is applied on these frames to obtain the difference image. After comparing it with the threshold, the resultant image is displayed and its addresses are stored in order to track it. The system works in real time with minimum time lag between the capture and display. Moreover the entire system is optimized in terms of speed, memory requirements as well as the number of logic elements used which makes it suitable for application in real-time surveillance system.","PeriodicalId":383554,"journal":{"name":"2016 IEEE Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126927600","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}

Primarily, we frame analytical expressions for the throughput and energy efficiency of UW-ALOHA for single hop UASN. We then procure closed form expression for the optimal channel attempt rates that maximize energy efficiency and throughput Independently. In this case, we notice that the attempt rate that maximizes the energy efficiency leads to drop in the network throughput and vice versa. We then consider a cross layer energy optimization problem with the objective of maximizing the energy efficiency of the network while meeting an SNR constraint at the PHY layer and a throughput constraint at the MAC layer. We also consider underwater acoustic channel specific parameters like distance dependent bandwidth and spreading losses for the analysis. Using Karush-Kuhn Tucker conditions, we derive closed form solution for the optimal channel attempt rates that meet the desired objectives. Extensive performance evaluation results show that sensible selection of the attempt rates by the sensor nodes can improve the energy efficiency of the network significantly.","PeriodicalId":383554,"journal":{"name":"2016 IEEE Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127868860","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}
