A brief discussion will explain the choice of Direct Conversion receiver architecture in mapping the specifications in this study. The focus of this study is on Adjacent Channel Selectivity (ACS) and In-band Blocking requirements. The specification tables were translated into graphical diagrams that visualize the spectrum around the required channel frequency at Zero-IF. This illustrates channel filter frequency response which allows for easier design procedures.","PeriodicalId":132198,"journal":{"name":"2012 IEEE International Conference on Electronics Design, Systems and Applications (ICEDSA)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123787477","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}

For a data rate of 1 Mbps and carrier frequency of 1 MHz, the proposed demodulator achieved a 100% data rate to carrier frequency ratio.

In this paper several techniques have been taken into consideration which can improve the efficiency of thin film solar cell like CIGS and ZnTeO. Simulations have been performed to optimize the parametric values that can greatly influence the efficiency of thin film solar cell. Effect of change of cell width, transmittance, recombination lifetime etc. on the conversion efficiency has been studied and optimized in MATLAB. It has been found that thin film solar cells with larger cell width can provide better efficiency only when the minority carrier mobility of the cell material crosses a critical value. If the mobility of the cell material is below this critical value, the efficiency of the cell decreases with increase in cell width.","PeriodicalId":132198,"journal":{"name":"2012 IEEE International Conference on Electronics Design, Systems and Applications (ICEDSA)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132113535","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}

Recently, an increasing amount of wasted lubricant has been due to the unnecessary changing of lubricant even though the lubricant still remains its lubrication behavior. Therefore, a condition based technique is introduced to monitor the degradation parameters in lubricating oil by using optical approach. This work focuses on Total Acid Number (TAN) that has been identified as the main parameter in determining the lifetime of lubricant and it occurred at band location from 1,050-1,250cm-1 and 1,700-1,730cm-1. The best input parameter has been identified for sensor development and signal processing. Then, the prediction model is used to validate the measured and the predicted value of degradation. The high correlation between the predicted and measured data shows the prediction algorithm can be used for prediction purposes efficiently.","PeriodicalId":132198,"journal":{"name":"2012 IEEE International Conference on Electronics Design, Systems and Applications (ICEDSA)","volume":"13 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113964465","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}
