Owing to its economic and environmental importance, MIC has been the subject of extensive studies for the past five decades Sulfate-reducing bacteria (SRB) is one of the agent that colonize metal surface and cause localized corrosion. The present study was carried out to gain an insight into biochemical aspect of oxidoreductase of sulfate-reducing bacteria (SRB) which is possibly responsible for MIC. A computational approach was employed to obtain informations of protein domain architecture, biological processes, subcellular locations, physicochemical properties and protein-protein interaction network. By using as series of online publicly available bioinformatics tools, our comprehensve data has increased our understanding of mechanisms governing MIC by SRB. We suggest that, the deterioration of metal may be contributed by the electron flow from metal surface to metal ion-binding domains of SRB oxidoreductase. The acquired electrons are utilized by SRB to support energy production and its colonization on metal surface The participation of SRB oxidoreductase in high number of protein-protein interaction also may be important for establishment of SRB biofilm on metal surface The discovery of these informations are very useful for further wet lab approach to characterize the biofilm-metal surface interaction.","PeriodicalId":193430,"journal":{"name":"2011 International Symposium on Humanities, Science and Engineering Research","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125878184","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}

A fundamental component of resource management is transmitter power control and an efficient power control technique is essential to support system quality and efficiency. The data transmitted from the sensor nodes is highly susceptible to error in a wireless environment which increases the transmit power. Error control coding (ECC) schemes can improve the system performance and has an impact on energy consumption as node energy is sturdily influenced by the modulation and error correction coding used. This paper proposes a power control solution for wireless sensor network (WSN) considering MIDRS code in the analytical setting of a game theoretic approach. The game is formulated as a utility maximizing distributed power control game while considering the pricing function and the existence of Nash equilibrium is premeditated. From the analysis it is evident that the system is power stable only if the nodes comply with certain transmit power. The utility of nodes employing RS and MIDRS codes is compared; the results show that employing MIDRS achieves the best response for the sensor nodes by consuming less power.","PeriodicalId":193430,"journal":{"name":"2011 International Symposium on Humanities, Science and Engineering Research","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121502498","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}

This novel approach of operating an induction motor with RSW supply is presented in this paper. The analysis of operation of the motor, supplied with RSW power supply is carried out using standard mathematical simulation tools and the results are presented here. The motor characteristics with proposed RSW supply is compared with the operation under conventional sine wave (CSW) supply and the advantages and improvements are highlighted. Hardware implementation along with algorithm is also proposed. The algorithm is compared with various PWM schemes such as Sine-triangle PWM (SPWM), Space Vector PWM (SVPWM) implemented using micro controller / microprocessor based pulse generator.

Our research has four objectives: a) to investigate learners' reasons for studying Chinese as a third language; b) to determine specific knowledge and skills learners wanted to acquire c) to examine the suitability of the contents of three textbooks; d) to conduct a content analysis of the textbooks and the supplementary teaching materials. This article will report only on the first three objectives. A total of 503 Malay students from 17 faculties who were following the third level Chinese course and 24 Chinese language lecturers, all users of the textbooks, answered questionnaires which we developed for this study. Our research findings revealed that two main factors motivated students to take up Chinese as a third language: the desire to master an additional language and to enjoy the economic advantages of mastering the Chinese language. The cultural factor was not an important motivation. Evaluation of the content of the current textbooks by both students and lecturers showed that almost all the contents were considered still relevant and necessary for teaching and learning Chinese at the university. Comments and suggestions to improve the content of the current textbooks were also proposed by the textbooks users. These findings will be used in the designiing and development of teaching materials to meet course objectives and increase students' motivation for taking Chinese as a third language at tertiary level.","PeriodicalId":193430,"journal":{"name":"2011 International Symposium on Humanities, Science and Engineering Research","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128359420","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}

It is often the starting point for other processes like analysis, visualization and quantization. In brain diagnostic system, segmentation is essential to study many brain disorders. Several popular clustering techniques for segmentation are available. Fuzzy c-means (FCM) is one such soft segmentation technique applicable for MRI brain tissue segmentation. The performance of this method to obtain an optimal solution depends on the initial positions of the centroids of the clusters. In the existing FCM, the centroids are initialized randomly. This leads to increase in time to reach the optimal solution. In order to accelerate the segmentation process an application specific knowledge is used to initialize the centers of required clusters. To segment brain portion, we use the knowledge about the MRI intensity characteristics of brain regions to initialize the centroids. The performance of existing FCM and the proposed approach with centroid initialization is evaluated by applying the methods on several datasets. The comparison is done in terms of processing time and the values obtained as final centroids. The proposed approach produced the optimal results within 14–18 iterations in 2.5–11 sec/slices while the existing FCM took 3.5–15 sec/slice. The results indicate that the knowledge about the datasets to be clustered can be used effectively to initialize the centroids for FCM algorithm. The results reveal that the proposed method with 14 iterations is sufficient to segment the normal brain volumes.","PeriodicalId":193430,"journal":{"name":"2011 International Symposium on Humanities, Science and Engineering Research","volume":"93 15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126040293","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}
