The system is implemented in water heating. The main objective is to build a PV heating system which is able to absorb solar energy and convert into electrical energy; with the available electrical energy, thermal energy is produced. It is an off-grid system. The system consists of PV panel, controller, battery, inverter and heating element. PV panel generate DC power from the solar energy. The electrical energy is stored in battery. Heating element is an AC load, and inverter is needed to convert the DC power into AC power. The overall system is managed by controller. Function of each module in the system is further discussed in this paper. Simulation was done to prove the methodology of the system works","PeriodicalId":277771,"journal":{"name":"2010 IEEE Student Conference on Research and Development (SCOReD)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133576663","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}

Alternative public key encryption can solve these two problems such as Elliptic Curve Cryptography (ECC). Mathematic background of ECC is based on coordinate systems that two main arithmetic operations are explained and RSA encryption and ECC encryption key lengths have compared with diagram. Essentially, this paper is mentioned ECC over binary field F2m for global smart card systems with four applications. Main contribution of this paper is to propose ECC public key encryption in global smart card which is explained four applications of global smart card.","PeriodicalId":277771,"journal":{"name":"2010 IEEE Student Conference on Research and Development (SCOReD)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133597191","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}

There are three importance mechanisms in producing high efficiency cells to harvest solar energy; reduction of reflectance, light trapping in the cell and higher light absorption. The work presented in this paper shows studies conducted in surface texturisation of single crystalline silicon solar cells using wet chemical etching techniques. Two etching types are applied; alkaline etching (KOH:IPA:DI) and acidic etching (HF:HNO3:DI). The alkaline solution resulted in anisotropic profile that leads to the formation of inverted pyramids. While acidic solution formed circular craters along the front surface of silicon wafer. This surface modification will leads to the reduction of light reflectance from the surface and thereby increases the short circuit current and conversion rate of the solar cells.","PeriodicalId":277771,"journal":{"name":"2010 IEEE Student Conference on Research and Development (SCOReD)","volume":"190 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114555201","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 approach of these technique are using inverse filtering which specifically involving Wiener filter to remove the noise and blur simultaneously in the CT image further restore the degraded CT image. CT scan image usually showing less detail visualization of soft tissue compare to Magnetic Resonance Imaging (MRI) scan image. The new CT image after restoration technique showed significantly high contrast compared to the original CT image produced by the CT scan machine. This procedure also shows comparison of different values use for noise to signal ratio (NSR) inWiener filter equation to generate the estimate output of CT image.
