The proposed design of the switchable filter is used in space applications for frequency switchability where electromagnetic spectrum can be effectively utilized. In this paper, RF MEMS Switches are used to achieve tunability between two frequencies. MEMS switches are used since they provide very low loss, do not require any dc current and offer a very low power approach for tuning application. The filter and the switches are designed at a frequency of 2 and 3 GHz. RF performance of switchable filter is carried out using Advanced Design System (ADS).","PeriodicalId":372799,"journal":{"name":"2012 IEEE Students' Conference on Electrical, Electronics and Computer Science","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116673659","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}

In order to provide more flexibility and emphasis over this domain, an algorithm is presented which can be used to draw the device band diagram in any plane in either direction for a user specified biasing conditions. Algorithm uses a three dimensional matrix of the device, which is reduced to a two dimensional matrix and subsequently into a vector, after plane and line selection by user. Basics of device level tool development are highlighted through this approach. This work is useful to the students and device level engineers, offering them an interactive and flexible way to draw band diagram anywhere in the device.

However ARP is an all trusting protocol and is stateless which makes it vulnerable to many ARP cache poisoning attacks such as Man-in-the-Middle (MITM) and Denial of service (DoS) attacks. These flaws result in security breaches thus weakening the appeal of the host for exchange of sensitive data. There have been several solutions, proposed to solve this problem. We have analyzed that no solution offers a feasible solution. Hence, this paper presents an efficient and secure version of ARP that is able to cope up with all these types of attacks and is also a feasible solution. It is a stateful protocol, by storing the information of the Request frame in the ARP cache, to reduce the chances of various types of attacks in ARP. It is more efficient and secure by broadcasting ARP Reply frame in the network and storing related entries in the ARP cache each time when communication take place.","PeriodicalId":372799,"journal":{"name":"2012 IEEE Students' Conference on Electrical, Electronics and Computer Science","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123293338","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 model system which we study is the gyroscopes which has attributes of great utility to navigational, aeronautical and space engineering and have been widely studied. This Gyro has a chaotic vibration for some range of parameters. To control the chaotic vibration of this system, a switching surface is adopted so that it becomes easy to ensure the stability of the error dynamics in the sliding mode. Then an adaptive sliding mode controller (ASMC) is derived to guarantee the occurrence of the sliding motion. The adaptive laws are derived in the Lyapunov sense to guarantee the stability and tracking of the controlled system. Two different desired responses are considered in this study and the effectiveness of the proposed method is shown for both cases.","PeriodicalId":372799,"journal":{"name":"2012 IEEE Students' Conference on Electrical, Electronics and Computer Science","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125379706","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}

Wind energy is one of the fastest emerging renewable alternatives for the electrical supply around the world.

The analysis is conceded out to find number of gates, memory and speed requirement in FPGA for the two methods. As Recently the field programmable gate arrays have enjoyed wide spread use due to several advantages related to relatively high gate density, short design cycle and low cost.
