Assuming perfect knowledge of the instantaneous channel gains for the whole system, we propose a joint resource allocation scheme aiming at maximizing the energy efficiency of the system. We first select the best relay node from all the potential relay nodes and then employ subcarrier pairing, and finally we apply joint power allocation and bit loading. Simulation results show that the proposed scheme can significantly improve the energy efficiency of the system. And we also find that bit loading has more effect on the performance of the system than subcarrier pairing does.","PeriodicalId":415759,"journal":{"name":"2013 IEEE Third International Conference on Information Science and Technology (ICIST)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128605638","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}

To reduce the logic resource consumption (LRC) without any obvious increase of the bit-rate, this paper simplifies the calculation of the block matching parameter with replaced pixel-bits and replaced pixels, and discusses how the LRC of ME module and the bit-rate are affected by the number of replaced bits and replaced pixels for different video motion scenes based on FPGA. The experimental results show three reasonable optimization approaches, in which the ratio of bit-rate increment is less than 0.47% and the LRC drops 24% to 45% compared with full search (FS) algorithm.","PeriodicalId":415759,"journal":{"name":"2013 IEEE Third International Conference on Information Science and Technology (ICIST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129539545","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}

PID-type controller may encounter many problems, such as large overshoot, long adjusting time and even poor stability in the control of decomposition furnace with time delay. Hence, according to the characteristics and difficulties of the decomposition furnace control, a fuzzy immune self-adaptive PID control method is brought forward and designed in detail. At last, the field application experiments proved that the fuzzy-immune PID control is an effective arithmetic with the advantages of quick response and good robust in control of outlet temperature. Using the method can achieve ideal control effect.","PeriodicalId":415759,"journal":{"name":"2013 IEEE Third International Conference on Information Science and Technology (ICIST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114357859","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 high-precision weighted Bounding Box (HPWB) algorithm is proposed to improve the localization accuracy of original Bounding Box algorithm. In HPWB algorithm, unknown nodes are divided into three categories according to the number of neighbor anchors. As for nodes in category one, a weighted method based on RSSI (Received Signal Strength Indicator) is proposed. As for category two and three, an exclusion method is presented. Simulation results show that our proposed algorithm HPWB achieves higher precision, compared with the original Bounding Box algorithm and Weighted Centroid algorithm.","PeriodicalId":415759,"journal":{"name":"2013 IEEE Third International Conference on Information Science and Technology (ICIST)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116325170","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}

AMDAR data is of high resolution on spatial and temporal, which can provide vital information for the short-term forecast of strong convection weather in the airport terminal area.

The case studied in this paper is a strong convection at April 2011 in Guangdong Province, AMDAR data, together with multi-source information such as radar, satellite and air sounding is analyzed. The study has found that with high resolution spatial and temporal AMDAR data, wind and temperature disturbance information could reveal the motion of wind shear and turbulence in the airport, so that the unique observational basis for protecting the aircraft's take-off and landing safety is provided.","PeriodicalId":415759,"journal":{"name":"2013 IEEE Third International Conference on Information Science and Technology (ICIST)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124455005","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}
