Then a compensation technique, Interpolated Second Order Polynomial (ISOP) method, is studied to improve the frequency response of the traditional CIC filter, which can enhance the performance in pass-band. However, this kind of filter will reduce the attenuation in stop-band at the same time. In order to deal with this problem, this paper proposes Cosine filter, which is cascaded before CIC-ISOP to implement pre-filtering. By analyzing frequency characteristics, this cascaded filter enlarges the attenuation in stop-band and sharpens the transition band. With this method, we can obtain the improved and ideal magnitude response, and the results of this approach come up to the requirements of GSM RRU system.","PeriodicalId":353239,"journal":{"name":"2010 WASE International Conference on Information Engineering","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129129425","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 previous design model of intake port was tested in the steady flow experiment system which provided the boundary condition for simulation calculation. The three-dimensional CAD model of intake port was built and then it was putted into AVL–FIRE platform to do CFD simulation with appropriate turbulence models and calculation methods. The detailed information of air flow field and discharge coefficient, swirl ratio of intake port was obtained by CFD simulation. Then the previous intake port structure was optimized to improve intake port performance. The research shows that CFD simulation is an efficient way to design engine intake port; Air flow condition is complex in the intake port and the parts nearing valve seat. Two improvement programs were discussed in this paper that can increase the air flux and improve the air flow condition.","PeriodicalId":353239,"journal":{"name":"2010 WASE International Conference on Information Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121582222","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}

First, edges are extracted using a canny detector. Then, a local line detector is developed, and edge-pixels are labeled on the basis of the information provided by the local line detector. After egde labeling, the approximate location of the corners are determined. Finally, the minimum moments of the phase congruency information is used at a local window to determine the accurate location of corners. The advantage of the proposed method is that it does not involve calculation of the curvature and the threshold value. Experimental results demonstrate it is particularly effective for natural images, and possesses a high detection rate than the present methods.","PeriodicalId":353239,"journal":{"name":"2010 WASE International Conference on Information Engineering","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114755786","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, as the cases of 3 different cooling and heating systems such as GSHP, air source heat pump (ASHP) and air-cooled chiller for cooling and boiler for heating for an office building in Guangzhou, China. The emergy analysis of the each case was conducted and its emergy sustainability indices were established. The results show that the competitiveness of the GSHP system is no advantage to the air-cooled chiller for cooling and boiler for heating system and ASHP system, but its pressure to the environment is obviously smaller.
