It consist of an array of antennas illuminates the breast, to be used both as signal source radiating elements and the receiver of scattered waves. In order to enhance the detection process, breast imaging employs a coupling medium between an antenna and the breast. Therefore, it is essential to understand the behavior of the antenna in the coupling medium. In this paper, a sleeve monopole antenna with a top load is taken to cover the frequency band from 500 MHz to 3000 MHz. Corn syrup as a coupling media is used to achieve best matching with the real tissue. The proposed antenna is simulated in coupling media and results are presented in comparison with that of free space with the help of High Frequency Structure Simulator (HFSS). The selected antenna then optimized to radiate inside the coupling medium.","PeriodicalId":383554,"journal":{"name":"2016 IEEE Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"39 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":"115019858","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 K-user MIMO X-network is a communication architecture where each transmitter, equipped with multiple antennas, has independent messages for each of the receivers, also equipped with multiple antennas. Earlier only 2 × N or M × 2 X networks were considered to be achievable. In this paper we remove this restriction by employing time division multiple access scheme. The proposed IA scheme allows each user to achieve a degree of freedom of KA/2K-1 a particular time slot, where A is the number of antennas at each transmitter and receiver. The capacity and bit error-rate (BER) performance of the proposed scheme is compared to that of another scheme recently proposed by Park and Ko. Simulation results are reported to show the BER performance for K-user (for a toy example, K is set equal to 3) and two-user X channel IA in case of transmission over flat-fading Rayleigh channels.","PeriodicalId":383554,"journal":{"name":"2016 IEEE Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"30 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":"115039482","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}

Electric motors are the sources to drive or direct any equipment with mechanical perspective. This paper mainly focuses on the application of linear motion motors for the linear movement of image sensor. From the various electrical motors, stepper motor has advantage of micro stepping ability to manoeuvre it as per needed steps. Stepper motor miniaturized scale venturing is finished by pulse width modulation of a varying current. Considering the accuracy of every step is 3% to 5% and error inside the last step can't be collected into ensuing step, the stepper motor has higher position preciseness and sensible repetitive motion make them increasingly attractive for the image sensor applications. In this paper, diverse electric motors are examined and compared to see the benefits of each motor and identify the one that is more suitable to be utilized as a part of the movement of sensor/lens.","PeriodicalId":383554,"journal":{"name":"2016 IEEE Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"111 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":"122054642","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}

Chip level implementation of such optical circuits is under intense investigation by the research community. This work proposes an optical implementation of functionally reversible Carry-Skip Adder (CSA) circuit. Semiconductor optical amplifiers (SOA) based Mach-Zehnder interferometers (MZI) have been used to design the CSA circuit. Two separate designs of CSA are demonstrated. In the first design, a n-bit optical CSA is designed by considering 2-bit CSA module as a basic building block, whereas in the second design, multiple 4-bit CSA blocks are integrated to design the same n-bit optical CSA circuit. Comparative analysis with existing optical adder circuits shows that both the designs are cost and delay efficient compared to the existing designs.","PeriodicalId":383554,"journal":{"name":"2016 IEEE Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"42 2 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":"131936904","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}

NFC is a short range high frequency and low bandwidth wireless communication technology. Passive Radio Frequency identification (RFID) tags are usually used with a system where one end of communication is isolated and powerless in nature. There are several applications of RFID-NFC systems despite of its drawback such as communication can happen between only two devices at a time and, its short range (0-20 cm). In this paper, the simulation results of a novel antenna at 13.56 MHz are presented. NFC works on both active and passive devices using various modes of operation. Its short-range property is utilized here for authentication of degree certificate awarded by universities. The antenna is flexible, robust and light weight so that it can be easily sandwiched inside the paper. In this paper a NFC antenna is designed which is ideal for manufacturing and assembling into the thin layers of degree certificate paper issued by examining authority. Calculations are done to select antenna dimensions before the final process. An antenna design is achieved using simulations and parameter optimization with simple method without making it complicated.","PeriodicalId":383554,"journal":{"name":"2016 IEEE Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER)","volume":"35 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":"115778663","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 technique is programmed to identify stiction, and stem alignment faults. Video of the process captured from camera is acquired on to the system for processing, identifying and isolating the faults by analyzing the fault signature.

To mitigate the effects of higher attenuation in the mmWave band, the standard advocates the use of directional antennas. To provide channel access during CBAP, the coverage area around the AP can be divided into several quasi omni (QO) levels. In this paper, our focus is on uplink channel access during CBAP in which every multi-gigabit station (DMG STA) under a QO level contend for channel access using CSMA/CA protocol. We develop an accurate analytical model to compute the saturation throughput of each QO level and that of the network in the CBAP, by closely following the 802.11ad MAC specifications.

In the present design we use three CAs instead of four for two channels. This reduction in CA count not only reduces the capacitance area but also the total energy required to charge and discharge the CAs.
