A control module was developed to lighten labor intensity and guarantee experiment safety in the ESGHIS. A multi-function card PCI-1711 was selected as the core of the control module, which has high-speed data acquisition and digital/analog output. A relay OMRON/G2R-1 was used to automatically manage the startup/stop of units. A solenoid valve VP542 and a gas-control valve NV1-20-6M-ATC were used to operate overpressure protection. PLC TEMI550 was used to control programmable high-low temperature test chamber HLT705P through connecting it to a computer using a RS232/RS485 converter I-7520. A proportional valve and a stepper motor were used to control lifting and rotary speed of the drilling pipe in mini-drilling module. The corresponding software was coded by using multithreading and Visual C++6.0 language. It had good quality on interface, maintainability and expansibility. The whole module was operated successfully in the experiments of gas hydrates formation and mini-drilling simulation. It worked steadily, executed quickly and had high sensitivity for overpressure protection, which largely lightens the experimental intensity of the labor and enhances the safety of the experiments.","PeriodicalId":22230,"journal":{"name":"TENCON 2008 - 2008 IEEE Region 10 Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76403601","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}

By generating high quality movies of the brain in action, it helps to determine which parts of human brain are activated by different task performances. The process can be modeled as a linear mixture of independent localized sources of oxygenation, where no a priori information is known about their properties. Here independent component analysis (ICA) is used to understand the brain functions and to explore spatiotemporal features in fMRI data. It has been especially successful to recover brain function related signals (task related and physiology related signals) from recorded mixtures of unrelated signals (noise). Due to the high dimensionality, high noise level and spikes (due to high sensitivity of MR scanners) analysis of fMRI data and order selection, i.e., estimation of independent component is critical. We have tried to find the independent components by a number of ICA algorithms from which Extended Efficient FastICA and Combi ICA are found to have better performance as they are robust to outliers (caused due to high sensitivity of MR scanners) and the accuracy in terms of Amari Performance Index is more as compared to others. In this paper we 1) describe fMRI data and its properties, 2) and show that the combi ICA faithfully separates the independent components from fMRI data.","PeriodicalId":22230,"journal":{"name":"TENCON 2008 - 2008 IEEE Region 10 Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82668459","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}
