Technicians could operate interaction electronic technical manual (IETM) and get remote technical support from the wireless local network. To allow the technicians work unencumbered by the device, Head mount display (HMD) and Voice user interface (VUI) are utilized for hands free operations and meet technicians' requirements. What's more, for the Voice user interface operates in the strong background noise environment, double microphone speech enhancement technology based on recursive least squares (RLS) algorithm is utilized to eliminate the noise. The result proved that the wearable system could increase user's labor efficiency and reduce the cost for factories.","PeriodicalId":321908,"journal":{"name":"2012 International Conference on Computational Problem-Solving (ICCP)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116551006","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, we study the low-complexity design issue of energy-efficient radio resource allocation in downlink OFDMA networks. Distinguished from the existing works, we focus on the tradeoff between the energy efficiency and the total transmit power. The closed-form optimal solution is obtained by solving the first-order optimality condition of the energy efficiency maximization problem. Furthermore, based on the analytical solutions, we develop a low-complexity optimal algorithm for the energy-efficient resource allocation. Simulation results show that the proposed algorithm achieves the optimal energy efficiency with significantly lower computational complexity compared with the conventional iterative methods.","PeriodicalId":321908,"journal":{"name":"2012 International Conference on Computational Problem-Solving (ICCP)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134420087","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 future of IT industry lies in cloud computing. In recent years, many countries in the world respond enthusiastically to cloud computing. The U.S., Japan and European countries have created strategies to develop cloud computing, aiming to become the leader in the new era. The Chinese government also sees cloud computing as a historic opportunity to rebuild competitive advantages and leapfrog western countries. Against this backdrop, this article compares and contrasts the evolution of IT towards cloud computing between China and western countries especially the U.S. Due to differences in cultures, development stages of IT industries, roles of governments as well as IT companies, we believe future cloud computing ecosystems will be very different between China and the U.S. Fully understanding these differences will greatly help governments as well as companies identify right strategic investments.","PeriodicalId":321908,"journal":{"name":"2012 International Conference on Computational Problem-Solving (ICCP)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133617125","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}
