However, this property also implies that the runtime efficiency, in terms of both performance and power-consumption, can be affected by the implementations of JVM. In this paper, we present a case study of performance-power analysis of JVM implementations. We run SPECjvm2008 with OpenJDK and IBM I9 on an Atom-based netbook with Ubuntu operating system. Our observations are as follows: (1) the relative performance of OpenJDK ranges from 44 to 289% of J9, (2) the dynamic power consumption ranges from 2.8 to 7.2 Watts among benchmark programs. However, the power consumptions of two JVMs for the same workload are relatively similar. Therefore, the power-performance efficiency is mostly affected by the relative performance. (3) the effectiveness of multi-threading varies among benchmark programs as well as among JVMs. In general, running benchmark with a single-thread loses more in performance than in power consumption. Exceptions are compress, fft.small (OpenJDK only) and lu.small. (4) for most benchmark programs (except scimark), the power consumptions seem to be correlated to linear and square root of L2 reference and L2 miss rates, respectively.","PeriodicalId":102808,"journal":{"name":"ICIMU 2011 : Proceedings of the 5th international Conference on Information Technology & Multimedia","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127440653","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 author has implemented quantitative analysis by generating mathematical algorithms to compare efficiency between conventional and Agent Centric REA Modeling. However, most of the end users do not really understand the representation of mathematical algorithms. Hence, agent derivation mathematical algorithms have been converted into a simulation tool which plays a vital role in performing qualitative analysis, which involves the analysis towards agent centric simulation system's usability from users' perspective. The amount of 20 third year students from department of Science and System Management, Fakulti Teknologi dan Sains Maklumat (FTSM), Universiti Kebangsaan Malaysia were chosen randomly as qualitative comparison's sample, based upon their knowledges in REA modeling. Respondents will be asked to test both system prototypes translated from event approach and agent approach. Results towards mathematical formulas' simulation test shows that the total amount of redundant entity nodes generated by using conventional REA modeling technique always higher than the suggested methodology which proposes agent approach. Besides that, in the aspects of qualitative comparison, results clearly shows that 100% of the sample agreed that the prototype system was which translated from agent approach is able to generate final output faster and more accurate, besides requiring the minimum modeling steps. In addition, agent approach translated system prototype provides the maximum and optimum level of users' comfort; satisfaction and ability to increase REA modeling know ledges for the system's users.","PeriodicalId":102808,"journal":{"name":"ICIMU 2011 : Proceedings of the 5th international Conference on Information Technology & Multimedia","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131043437","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}

Prolonged network lifetime and scalability are important requirements for many sensor network applications. Clustering is an effective topology control approach in wireless sensor networks, which can increase network scalability and lifetime. Clustering sensors into groups so that sensors communicate information only to cluster heads and then the cluster heads communicate the aggregated information to the processing center, may save energy. The weakly connected dominating set (WCDS) is very suitable for cluster formation. Then we find a suitable route for sending packets with a new routing algorithm with the help of the created cluster. In this paper, we propose a distributed, algorithm for WCDS construction in wireless sensor networks based on distributed learning automata. To evaluate the performance of the proposed algorithm several experiments have been conducted.","PeriodicalId":102808,"journal":{"name":"ICIMU 2011 : Proceedings of the 5th international Conference on Information Technology & Multimedia","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133260867","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}

However, problematical use of the Internet can lead to various types of mental and physical problems. Internet Addiction (IA) is a disorder which is caused by problematical Internet usage. This study aims to determine the situation of Internet Addiction in UNITEN, Malaysia by looking at the Internet usage patterns. How is the Internet Addiction situation in UNITEN, Malaysia? What are the profiles of the Malaysian Internet Users? The research employed a quantitative approach. Data collection was based on a web-based and paper-based survey of 700 college students in Malaysia. The questionnaire survey was developed based on Dr. K. Young's Internet Addiction Test (IAT) and Internet Addiction Diagnostic Questionnaire (IADQ). The respondents were then categorized into 3 levels of Internet Addiction: mild, moderate and severe Internet Addiction. A comparative analysis was performed on the situation in Malaysia in which data on the pattern and the usage of Internet was already available. The survey which was carried out with 700 respondents, produced a 3 percent spoiled result, and found that 31 percent of the respondents are mild addicts, 63 percent are moderate addicts and only 3 percent of the respondents are severe Internet Addicts. Further details which include the profiles of Malaysian Internet users and the revision over published knowledge based on Malaysia Internet Addiction are provided in detail. Physical and mental problems caused by Internet Addiction consequently make problems for the society. An awareness of the Internet usage pattern and the situation of Internet Addiction help to prevent and control the negative consequences of this modern disorder.","PeriodicalId":102808,"journal":{"name":"ICIMU 2011 : Proceedings of the 5th international Conference on Information Technology & Multimedia","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132724214","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}
