Here, a simple optimum layout scheme for single-axis tracking photovoltaic systems using PVSYST is proposed. First, the photovoltaic array reference spaces in north-south and east-west orientation are determined following the actual engineering experience. Then, using the power generation capacity of unit cost as the optimization function, the photovoltaic array spaces are meshed twice to obtain the optimization parameters.

So the moving performance and positioning accuracy of every motorized axis are crucial to the measurement. This paper proposed a new motion control technique for linear translation stages with stepper motor. The control algorithm was realized on field programmable gate array (FPGA) and digital signal processor (DSP), and met the high-efficiency and high-precision measurement requirements. An efficient and optimized speed control performance was achieved by using a method that was based on speed-difference driving and speed-table supplying, and a high-precision, closed-loop positioning control performance which has an error less than +0.3μm was achieved by using a method that was based on position feedback, position-window restriction and time-window restriction.","PeriodicalId":386083,"journal":{"name":"2011 International Conference on Mechatronic Science, Electric Engineering and Computer (MEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125579393","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 order to realize the underwater voice communication, the required speech data compression rate should be much higher. So we select TLV320AIC12 and AMBE-3000 to realize the design of voice codec module. The TLV320AIC12 is a high-performance A/D & D/A chip with programmable input and output gain control, and AMBE-3000 is the latest vocoder which is based on the AMBE voice compression algorithm. Using this designed module, the call voice is clear and legible at the rate of 2.0∼2.4kbps which is a very low compression bit rate. The system features flexible speech coding rate, high cost-effective, low power consumption and many other advantages, which will build a good hardware platform for the long-distance underwater speech communication.","PeriodicalId":386083,"journal":{"name":"2011 International Conference on Mechatronic Science, Electric Engineering and Computer (MEC)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121515328","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}

It can operate in net-connected mode and islanded mode, when the operation switches between the two types of mode, the variety power will emerge. If this happens, the level of the system voltage will be fluctuating in a wide range, and the system frequency will also be fluctuating in an unacceptable range. The load power supply will be influenced seriously. To minimize the influence on load power supply, in this paper we adopt two different types of control strategy: invariable power control and invariable voltage control. Appling them to the distributed generators in different operation mode, we established simulation models. The result proves that the control strategy is valid.","PeriodicalId":386083,"journal":{"name":"2011 International Conference on Mechatronic Science, Electric Engineering and Computer (MEC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126395971","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 proposed a novel framework for measuring the feature selection and fusing two selected feature sets in steganographic detection field, based on KCCA theory. KCCA feature fusion method can outperform single feature and achieve similar performance to serial feature fusion method in steganographic detection field, while only costing 1/10∼1/8 of original time.
