Abstract: Exploiting the nature of broadcast and the relayingcompetence of wireless devices, cooperative communication isbecoming a shows potential expertise to enlarge the channel ability inwireless networks. In cooperative communication, the scheme forconveying relay nodes to users plays a critical role in the resultingchannel capacity. The Cooperative Communication (CC) is atechnology that allows multiple nodes to concurrently transmit thesame data. Wireless ad hoc networks are multi-hop structures, whichconsist of connections among wireless nodes without infrastructure.Cooperative communication which achieves spatial diversity bypractically using the relays as encouraging antennas for the originaltransmission is shown to do higher throughput and reliability. Incooperative communication, the choice of the relay node plays a veryvital role for improving the network presentation. Since cooperativemultiplicity could potentially increase system capacity and energyefficiency, it has become more and more attractive recently.Exploiting the nature of broadcast and the relaying capability ofwireless devices, cooperative communication is becoming apromising technology to increase the channel capacity in wirelessnetworks. In cooperative communication, the scheme for assigningrelay nodes to users plays a significant role in the resulting channelcapacity.

Volume: I , Issue: II

Publication Year: 2014 , Page(s): 7

 

Abstract: The World Wide Web has changed the way peoplecommunicate with each other and the way business isconducted. It lies at the heart of a revolution that is currentlytransforming the developed world toward a knowledgeeconomy and, more broadly speaking, to a knowledgesociety. This development has also changed the way wethink of computers. Originally they were used for computingnumerical calculations. Currently their predominant use isfor information processing, typical applications beingdatabase systems, text processing, and games. At presentthere is a transition of focus toward the view of computers asentry points to the information highways.

 

 

 

 

 

Experimental Study of Semi Rigid Connections and itsResistance against Earthquake

Manish V. Trivedi,Dr. R.P. Vasani

Volume: I , Issue: II

Publication Year: 2014 , Page(s): 8-13

 

Abstract: In analysis of the plane frame, generally we assume thatjoints of structure are fully rigid or ideally pinned. A fully rigid jointimplies that there is no relative rotation of one member with respectto other. Ideally pinned connection implies that no moment will betransmitted between members of connection.Although the use ofthese idealized joint behaviors simplifies the analysis procedures, thepredicted response of the frame may not be realistic because rigidconnections in steel structure permit a certain amount of rotation totake place within the connections. While pinned connections offer asmall amount of restraint against rotation. For more accurate analysisof structure, it is necessary to consider the connections as beingflexible or semi-rigid. Analysis and design based on consciousrecognition of the flexibility of the connections may result in a savingof material.

 

 

 

 

 

A Study on Fixture Design for Complex Part

Abstract: Upon completion of a successful Distribution Automation(DA) Pilot Project centered in National Grid’s upstate New Yorkservice territory, it was determined that the reliability improvementsdelivered by the pilot demonstration justified a much morecomprehensive effort to further evaluate additional Smart Gridtechnologies. The vision was to conduct experiments with a full suiteof Smart Grid technologies including: AMI; Home Area Network andenergy management systems; Automatic Fault Isolation & SystemRestoration; advanced feeder monitoring; distribution transformermonitoring; single pole tripping and Pulse Closing technology ondistribution line reclosers; advanced capacitor control withindependent pole operation; faulted circuit indicators with 2-waycommunication capability; and distribution fault locating capability.This vision came to be known as National Grid’s Smart Grid Pilotproposal. Many challenges exist with such a comprehensiveapproach from public and personnel safety, to ensuringinteroperability between devices and systems of differentmanufacture. In order to determine which technologies wouldprovide the most benefit to National Grid’s customer base, a meanswas needed to prequalify the various types of products availablebefore large scale deployments were initiated. Looking at the largenumber of Smart Grid device suppliers, architectures and productsavailable, we realized that the optimum solution would be to build afacility wherein a wide range of Smart Grid technologies could beinstalled and systematically put through their paces; i.e. actuallytested in as near a real- world atmosphere as practical. Thus was bornthe National Grid “Smart Technology Centre” or STC. Soonthereafter, National Grid’s Utility of the Future engineering teamdesigned, engineered, and constructed a truly innovative test fixturethat enabled system level testing on complex distribution networks toensure process safety during field deployment. One of only a fewknown organizations in the U.S., National Grid has in-housecapability to truly test and evaluate an end-to-end Smart distributionsystem architecture where systems such as automated faultisolation and system restoration can be evaluated.This paper will discuss interoperability testing that National Gridembarked upon to prepare for its proposed Smart Grid Pilotdemonstration and will detail the lengths that were taken increating a test site where medium voltage Smart Gridtechnologies could be fully evaluated to ensure that the variousapplications would play well with each other prior to actually beingdeployed in the field. Furthermore, this paper will focus on providingan overview of the system level testing and technical evaluation ofdistribution protection and control equipment with automated faultisolation and system restoration capabilities. It will also detail anumber of lessons learned from this effort and discuss futureplans for smart technology evaluation as a basis for an educationalplatform and workforce training tool.

Publication Year: 2014 , Page(s): 27-31

 

Abstract: Gait has been known as an effective biometric feature toclassify a person at a distance. Human gait recognition and theiractions from video sequences is currently a very energetic area ofresearch because of its application in video surveillance, realisticentertainment systems. A person can walk in any direction. It is notnecessary that person is walking parallel in front of the camera. Gaitrecognition is one of the second generation biometrics which does notrequire subject willingness. It is behavioral biometrics, can be capturefrom the distance and no-touching. Even a low quality video can beused for gait recognition so more and more researchers are interestedin it. This paper gives a brief survey of this second generationbiometric technologies and its methods i.e. gait biometrics.Keywords: Biometrics, Gait Recognition, computer vision, datasets.
