The SPFs are computationally intensive and they exhibit spatial or temporal parallelism or both. While the high performance DSP processors are unable to meet the speed requirements of these SDRs , System on chips ( SOCs) are also not suitable because of their limited flexibility.Recently, state-of-the-art FPGAs have emerged as high performance programmable hardware to execute highly parallel, computationally intensive signal processing functions because of the availability of in-built multiply and accumulate (MAC) units within these chips. Hence, FPGAs are becoming possible hardware platforms for implementing SDRs . Apart from that these FPGAs also include partial reconfiguration features that make them suitable for implementing SDRs efficiently as the configuration latency in run time trends to go down. This paper investigates the potential use of FPGAs for implementing efficient “Radio Processor”. The proposed Processor is based on a parallel re-configurable which was implemented on FPGA and exploits the spatial and temporal parallelism of the signal processing functions using a new concept “Reconfigurable Single Function Multiple Data( RSFMD)” architecture . The architecture was validated on Xilinx Virtex IV FPGA.","PeriodicalId":377688,"journal":{"name":"2009 International Conference on Education Technology and Computer","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127949755","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}

Two aspects need to be balanced out in order to optimize the economical success which is the number of unsold copies should be minimal to reduce the cost of production, and the sell-out rate should be minimal to maximize the number of sold copies. Thus, a good sales rate prediction is necessary to optimize both antagonistic aspects. This paper utilized Artificial Neural Network to predict newspaper sales for one vendor in the area of Sungai Petani, Malaysia. The predicted sales value can help the company to optimize their sales. The main objective is to develop a prototype that apply artificial neural network so that it can predict the future trend as well as the future daily sale. The network will consist of three layer which is input layer, one hidden layer and output layer. The input layer will have six input node where this will be the factor that will affect the output which is the number of copies that sold. The network will be trained with history data of a one year records of data. The output produced has the error value as low as 1.24% while the correlation coefficient between prediction and actual value is 0.1197","PeriodicalId":377688,"journal":{"name":"2009 International Conference on Education Technology and Computer","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124369071","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}

For educational purposes, ICT can be used to support teaching and learning as well as research activities including collaborative learning and inquiry. One of the main applications of ICT in higher education is curriculum development based on these new technologies.This research is concentrated on the obstacles, facilitators, and the risks of using these technologies in curriculum development in higher education. The main purpose of this research is to answer to the question that in which fields and to what extent there are obstacles, facilitators and the risks in using ICT in curriculum development at university level? This research has been done at the National University of Iran, the second largest university in the country; the research population consists of university academics and students. A questionnaire has been administrated for gathering the data. The main results are reported based on the following: the possible domains of using ICT in curriculum decision making in higher education; Obstacles of using ICT in curriculum development at university level; Facilitating factors and essential supports needed for application of ICT in curriculum development of higher education; and Advantages and disadvantages of using ICT for curricular activities at university level.","PeriodicalId":377688,"journal":{"name":"2009 International Conference on Education Technology and Computer","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129886345","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 online e-learning community system is an intelligent system that integrated e-learning, network community, and agent can automatically in performing the mechanisms of interaction and collaboration in a network community environment. However, how to build a complete instructional system design (ISD) before users or learners learning on online e-learning community are very difficulties. Because, before uploaded knowledge or contents of each teaching subject on online e-learning system, rarely managers or designers consider building a suitable ontology as an input, thus even there was a beautiful or friendly e-learning system also can not obtain a good learning result on online e-learning environment. Thus, this paper considers about above problem uses concept of operation management (input-process-output) into first phase of system design and development, and then uses ontological engineering approach building common domain knowledge before system design and development for the online e-learning community system.","PeriodicalId":377688,"journal":{"name":"2009 International Conference on Education Technology and Computer","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116959092","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}
