So a radix-2 pipelined FFT processor based on Field Programmable Gate Array (FPGA) for Wireless Local Area Networks (WLAN) is proposed. Unlike being stored in the traditional ROM, the twiddle factors in our pipelined FFT processor can be accessed directly. A novel simple address mapping scheme is also proposed. The FFT processor has two pipelines, one is in the execution of complex multiplication of the butterfly unit, and the other is between the RAM modules, which read input data, store temporary variables of butterfly unit and output the final results. Finally, the pipelined 64-point FFT processor can be completely implemented within only 67 clock cycles.","PeriodicalId":153175,"journal":{"name":"2010 Second International Conference on Computer Modeling and Simulation","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123104787","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}

Firstly, we gain three dimensional point clouds through the Lidar technology, and make high-precision Digital Orthophoto Map (DOM), which has the same scale as the real collection mural. Secondly, the spatial disease database will be built based on the DOM of collection mural with the GIS technology. Then we can get some useful dataset for protecting collection mural, such as disease map and trend map. Disease map, based on some spatial analysis and spatial statistics, will tell you where the disease is, and how serious the disease is. Lastly, but importantly, we can classify the disease grade based on the collection mural with decision tree. So protector of collection mural knows what’s the most serious disease. It is better than the traditional methods both in accuracy and efficiency. Finally, this article has confirmed the related method efficiency and the precision in the collection mural of Greatly Summons Temple.","PeriodicalId":153175,"journal":{"name":"2010 Second International Conference on Computer Modeling and Simulation","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122214625","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}

Refractory material behavior was described by Drucker-Prager plasticity model combined with strain softening material behavior at tension, and most of the material physical parameters changing with the temperature were considered. During the working process, a mechanical and thermal coupling diagram was introduced to optimize the geometric figure of the converter by software ABAQUS. The stresses of the converter were investigated, especially in the lower brick layers of the wall (the bottom wall transition zone). The result indicates a proper inclination at the joint between the bottom and wall of the converter can reduce the stress concentration, which make the refractory material damage decrease. Therefore the service life of the converter is expected to be prolonged.","PeriodicalId":153175,"journal":{"name":"2010 Second International Conference on Computer Modeling and Simulation","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121464110","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}

Hierarchical decentralized control strategy is employed in this paper in response to this difficulty. In this approach, the structure to be controlled is divided into a set of substructures, and each substructure is then controlled independently using its local information. (Finally A global coordinator will be used to coordinate among these local controllers) Harmonic controller eliminates interconnection of substructures. With LQR Active control algorithm in Matlab environment,the centralized control strategy was implemented on cantilever structure under earthquake excitation. Simulated results show that hierarchical decentralized control method has a good control effect with preferably suppressed displacement response and less control force. The study in this paper presents a promising means for structural control.","PeriodicalId":153175,"journal":{"name":"2010 Second International Conference on Computer Modeling and Simulation","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123354128","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}

How to select Cooperative Set (CS) is critical issue for COMP. Based on geometry criteria, this paper proposes two methods of cooperative area selections, ‘UE centric’ and ‘Networks pre-defined’. Simulations with realistic RRM structure and feedback assumptions show that UTRAN LTE downlink system performance could be greatly enhanced by COMP technology. UE centric CS selection provides the best performance gain at the expense of system complexity. Among network predefined CS cases, intra-site CS pattern is recommended with good performance in terms of sector and cell-edge throughput.","PeriodicalId":153175,"journal":{"name":"2010 Second International Conference on Computer Modeling and Simulation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122370934","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}
