The distribution of infinitely wide fringes is recorded by digital camera. Image processing is completed employing all raw data including peak and valley data and transition point data for a given height of interference fringe pattern. The quantity of effective fringes is confirmed and fringes phase extraction is carried out. The analysis indicates that the observed fringes of holographic reproduction is not all interference fringes; In the central area of phase distribution, the gradient of interference fringes is so small that it is vulnerable to impact of noise; In the large gradient region of phase distribution, phase distribution is nearly linear. The effect of various extraction methods using all raw data is similar.","PeriodicalId":271757,"journal":{"name":"2010 2nd International Conference on Computer Engineering and Technology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126687650","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}

Traditional PC104 computer is of many disadvantages such as fixed board layout and large power dissipation, which makes the system impossible to integrate the functions of signal collecting and navigation computing for reducing the power dissipation and size of board. In this paper, a new INS computer is designed using DSP TMS320C6713 and FPGA XC3S400AN. The computer integrates the signal collecting work by employing pulse subdivision method to avoid ±1 quantization error. Experimental results show that the new INS computer gets good performance on signal collecting (RMS of 10−3) and inertial navigation computing, brings decreased power dissipation (1.5W) as well, which makes it useful in INS application.","PeriodicalId":271757,"journal":{"name":"2010 2nd International Conference on Computer Engineering and Technology","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129219826","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 moisture absorption property of matrix and the tensile properties of matrix, fiber and laminate were tested under the status of unageing and ageing. Based on the tests, the residual strength of the glass fiber/epoxy laminate after water immersion ageing was calculated using a bridging model. The numerical results indicate that the theoretical values by the method presented in this paper are well fit with tests results. The results show that the model could be used to predict the progressing damage regulation and the strength accurately under the condition of low moisture absorption ratio. When the failure of main stress layers are controlled by fiber, the descending of fiber tensile strength caused by water immersion result in the descending of the laminate maximum tensile strength directly. The major factor of affecting the residual strength of laminate are matrix hardening and tensile strength descending caused by water immersion to the layers controlled by matrix. The effect of the low moisture absorption ratio on the fiber-matrix interface strength is finite.","PeriodicalId":271757,"journal":{"name":"2010 2nd International Conference on Computer Engineering and Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130595146","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 biogas engine and its performance parameters analysis is regarded as research object, the biogas engine model library was built based on the object-oriented language Modelica. The effect of compression ratio, ignition advance angle and the combustion duration on the performance of biogas engine was analyzed through simulation study. The optimization of operating parameters and design parameters of biogas engine was performed. Natural gas (33%, 67% and 100%) and liquefied petroleum gas (5%, 10% and 15%) were added to the biogas and were simulated as the fuel of SI engine. The effects of natural gas/liquefied petroleum gas-biogas blends on the performance of spark-ignition engine used for electricity production were numerical investigated. The results suggest that: There is an improvement in brake thermal efficiency and brake power with the addition of natural gas/liquefied petroleum gas in biogas. The feature of reusable and object-oriented of Modelica will enhance the modeling and simulation of biogas engine performance greatly not only in accuracy but simulation efficiency, this would be efficient for the theoretical design and the optimum work of the biogas fuelled engine.","PeriodicalId":271757,"journal":{"name":"2010 2nd International Conference on Computer Engineering and Technology","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123350190","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}
