In order to measure the performance of LQI, RSSI and PRR in IEEE 802.15.4 based wireless sensor networks, the experiments were conducted by varying distances between transmitter and base-station and transmit power level. Our experimental results show that the PRR depends on some factors such as LQI and RSSI including the distance between transmitter and base-station and the location of each of the sensor nodes.","PeriodicalId":131337,"journal":{"name":"5th International Conference on Computer Sciences and Convergence Information Technology","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128346232","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}

By investigating and studying the cases of the entrepreneurs from five big industrial clusters in our country, the paper proposes the incubation subjects, incubation environments and incubation atmospheres of the enterprising talents in industrial clusters, builds the evaluation cables of industrial clusters' venture incubation and venture performance, and tests its reliability and validity. Furthermore, multiple linear regression analysis method is applied to analyze the influences of venture incubation factors on venture performance in industrial clusters. Eight factors such as venture incubation subjects, incubation environments and incubation atmospheres are taken as multiple independent variables; two dimensions of venture performance are taken as dependent variables; and then all entry regression analysis method is applied to build a multiple linear regression equation of venture performance. All of the above studies have tested the influences and associate effects of the entrepreneurs' incubation system in industrial clusters on the venture performance and have revealed the mechanism of this system.","PeriodicalId":131337,"journal":{"name":"5th International Conference on Computer Sciences and Convergence Information Technology","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129273079","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 this paper, by introducing the stretching model and the vector differential adjustor, a character modeling method based on vector difference is proposed. With this method, firstly, a reference model, a vertical stretching model and a horizontal stretching model are constructed in accordance with the model structure of the human body; secondly, the vector differences of control points are obtained between the horizontal stretching model and the reference model, and between the vertical stretching model and the reference model; and then a vector difference adjustor is employed to interactively adjust the control points in the reference model; lastly, a realistic character model is automatically generated based on the control points' coordinates. Experimental results show that this method can overcome the problems associated with other methods, such as: the need to master professional model software, system requirements for large cumbersome model databases, cracks or holes generated in the result model, and make it easy for users to interactively build a realistic character model.","PeriodicalId":131337,"journal":{"name":"5th International Conference on Computer Sciences and Convergence Information Technology","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121286271","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}

We present a performance comparison of PingPong-128 with other stream ciphers selected in European Project Ecrypt called eSTREAM project, namely Dragon, HC-128, and Rabbit.

Online Transaction Processing (OLTP) systems are focused on the day to day business by being optimized for retrieving and modifying complete entities. Online Analytical Processing (OLAP) systems initiate queries on specific attributes as these applications are optimized to support decision making based on the information gathered from many instances. In parallel both hardware and database applications are subject to steady improvements. For example, today's size of main memory in combination with the column oriented organization of data offer completely new possibilities such as real time analytical ad hoc queries on transactional data. Especially latest development in the area of main memory database systems raises the question whether those databases are capable of handling both OLAP and OLTP workloads in one system. This Paper discusses requirements for main memory database systems managing both workloads and analyses using appropriate data structures.","PeriodicalId":131337,"journal":{"name":"5th International Conference on Computer Sciences and Convergence Information Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132353847","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 study examines the effect of three color combinations on the user's perceived attentiveness level and usability of using a three-line graph.

How to make use of the special space narration ability of virtual reality has become a new topic for the field of educational research. The subject of this research are fifth graders. Using 3D rendering and virtual realty, its is hoped to develop a sketch learning system that can design and develop teaching strategies and learning activities. Through clinical teaching, the results of different teaching methods in teaching higher graders to sketch were analyzed. The research found that the teaching outcomes of VR and conventional teaching methods were very similar.
