The antenna appears uncomplicated in design and undemanding for investigation. The lower operating band of the proposed antennas can be controlled by varying the perimeters of the radiating slot and the upper operating band depended on the perimeter of the modified coupling slots. The results of the experiment proposed antennas show the impedance bandwidths of the two operating bands, determined from 10 dB return loss, which are larger than 60% and 30% of the center frequencies. All simulation processes in this paper applied IE3D program to analyze and optimized the antennas.","PeriodicalId":132155,"journal":{"name":"2011 IEEE International Conference on Computer Applications and Industrial Electronics (ICCAIE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125261345","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 the recent times, Internet addiction had become a global concern to the human society. As the electronic world has become more and more common to the young, younger generations are alleged to be susceptible to the risk of Internet addiction. This research outlines a method to examine the addictive level to the Malaysians Internet surfing. The purpose of our study is to identify the Internet use among Malaysians and the relation of excessive use to the addictive level. We propose and devise an online survey to study the Internet use among the younger generations. The questionnaire consists of five subsections; such as the relevant demographic questions, the diagnosis of the Internet addiction level, related questions on the Internet surfing behavior, the reasons of excessive Internet usage, and the consequences of the addictive behavior. Participants of the online survey were selected randomly from Malaysia, ranging from the age of 7-year old to the age of 30-year old. We found that the Internet use of the younger generations was susceptible to the Internet addiction. The findings reflect that younger generations are vulnerable to the fantasized world.","PeriodicalId":132155,"journal":{"name":"2011 IEEE International Conference on Computer Applications and Industrial Electronics (ICCAIE)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132501454","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 previous researches have introduced fully or partially signature-based botnet detection approaches. In this paper, we propose a fully anomaly-based approach that requires no a priori knowledge of bot signatures, botnet C&C protocols, and C&C server addresses. We start from inherent characteristics of botnets. Bots connect to the C&C channel and execute the received commands. Bots belonging to the same botnet receive the same commands that causes them having similar netflows characteristics and performing same attacks. Our method clusters bots with similar netflows and attacks in different time windows and perform correlation to identify bot infected hosts. We have developed a prototype system and evaluated it with real-world traces including normal traffic and several real-world botnet traces. The results show that our approach has high detection accuracy and low false positive.","PeriodicalId":132155,"journal":{"name":"2011 IEEE International Conference on Computer Applications and Industrial Electronics (ICCAIE)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132373977","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 use of piezoelectric materials to capitalize on the ambient vibrations surrounding a system is a method that presents dramatic potential for power harvesting. The simplicity associated with piezoelectric micro-generators makes MEMS applications highly attractive. In such applications, mechanical vibrations from environment are harvested and converted into electrical energy. These micro-generators are designed as an alternative to a battery-based solution that is especially intended for remote systems. We propose a comparative study on the obtained results of the energy delivered from the ambient vibration-based MEMS energy harvester using the ANSYS and COVENTORWARE approaches.

The proposed controllers coordinated with SVC are applied to single-machine infinite bus system (SMIBS) for the sake of improvement of power system damping. Simulation results show effectiveness of the proposed controllers to damp out low frequency oscillations under different loading and fault conditions. Also, the results indicate that the control performance and robustness of FLC is superior to that of PSDC under different disturbances and loading conditions.","PeriodicalId":132155,"journal":{"name":"2011 IEEE International Conference on Computer Applications and Industrial Electronics (ICCAIE)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121785726","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}

An exponential approximation technique is used to deduce an analytically solvable governing differential equation.
