The wind project developer must verify whether there would be a risk on the existing broadcast links in the area before moving towards the construction phase. Geometrical wind turbine modeling can help in determining the scattering of the signal around and assess whether the signal reception in the vicinity will be affected. From ITU Recommendation 69-1/6, we establish a clear propagation methodology to determine the dynamic scattering from the rotor blades and the static scattering from the large pylon.","PeriodicalId":153464,"journal":{"name":"2009 Canadian Conference on Electrical and Computer Engineering","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126925228","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 paper introduces a digit-based text-independent distributed speaker identification (DSID) system over telephone channels within the DSR framework. In this DSID system, the hypothesized speaker model is derived by GMM-UBM model training using Aurora2 connected digit training speech data and maximum a posteriori (MAP) adaptation. The UBM technique for speaker models is incorporated into this DSID system to reduce the computational complexities significantly. Experiments on the Aurora2 speech recognition corpus show that GMM-UBM yields excellent performance for speaker recognition over telephone channels. Compared to the baseline system, we got 100% recognition accuracy for this proposed DSID within the ETSI DSR framework.","PeriodicalId":153464,"journal":{"name":"2009 Canadian Conference on Electrical and Computer Engineering","volume":"162 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123072400","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}

Due to submicron/nanometer technologies and critical short-channel effects, choosing a suitable MOSFET model for circuit design becomes increasingly important. However, the conventional MOSFET models normally set up for the typical gate-driven applications may not perform correctly and accurately for the bulk-driven applications in the advanced technologies. In this paper, three most widely used MOSFET models, including BSIM, EKV, and PSP, have been extracted for the modern technologies and used in the simulation of bulk-driven applications. Measurement data of fabricated devices are compared with simulation results from distinct models. Several critical MOSFET parameters have been chosen to compare and analyze MOSFET characteristics. The experimental results demonstrate the advantages of the bulk-driven technique compared with the gate-driven scheme. Finally, the performance of distinct MOSFET models is summarized in order to provide analog circuit designers with practical directives.","PeriodicalId":153464,"journal":{"name":"2009 Canadian Conference on Electrical and Computer Engineering","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121073153","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}

Omnidirectional and perspective camera technologies are integrated to create a robust vision system that combines the strengths of both camera types. A compact, inexpensive and highly modular design is presented in which system modules are stacked vertically. The vertical structure provides each module with an unobstructed 360 degree horizontal view of the surroundings and allows the omnidirectional cameras to directly guide an active camera to view a target point. The physical system design is detailed, along with a description of the system's hardware and software architectures. The hardware architecture is scalable and fully self contained, while the software architecture is built around a user datagram protocol (UDP) network, allowing the computational load to be distributed over multiple computers.","PeriodicalId":153464,"journal":{"name":"2009 Canadian Conference on Electrical and Computer Engineering","volume":"18 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113955286","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}

Part of the limitation comes from the poor context modeling used by a JPEG coder, which fails to take full advantage of the pixel correlation existing in both space and frequency domains. Consequently, context-based arithmetic coding is proposed in the literature to replace the Huffman coding used in JPEG for better rate-distortion performance. In this paper, we extend our previous JPEG compatible joint optimization algorithm to a context-based arithmetic coding scenario. Experimental results show that an extra of 10∼15% size reduction or 0.5 dB compression gain can be achieved on top of JPEG compatible joint optimization with the same level of complexity.","PeriodicalId":153464,"journal":{"name":"2009 Canadian Conference on Electrical and Computer Engineering","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134467206","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 new SFCL includes a bridge composed of 4 SCRs and 2 diodes, a superconducting coil and an ordinary bypass reactor. In normal status, the bridge works as a rectifier, the voltage across the coil is zero if the current of the coil keeps greater than the peak value of the load current. When a fault occurs, the fault current is limited in the first cycle by the coil, when the fault is detected, the bridge can be controlled working as two bidirectional switches and the coil is inserted in the ac circuit and the steady fault current can also be limited. By adding the bypass reactor, the cost of the new SFCL can be minimized. Parameter design and simulations are presented. The simulation proves the validity of the new SFCL.","PeriodicalId":153464,"journal":{"name":"2009 Canadian Conference on Electrical and Computer Engineering","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115924862","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}
