Eucalyptus is one of the popular open source private cloud software for building private and hybrid clouds. The benefits of this open source software for private clouds are highly efficient scalability, organization agility, and increased trust and control for IT. These studies perform tests on performance of the services of websites by using performance test tools - LoadUI and Web Performance Load Tester with some security issues purposed. The six evaluation of the performance tests are 1) average response time 2) peak response time 3) error rate of data transmission 4) throughput 5) request service per second and 6) amount of concurrent user in the system. By comparing performances with dedicated server (not on cloud), the test results from these two programs show average response time of website on cloud server is less than website on dedicated server, peak response time of website on cloud server is less than website on dedicated server, error rate of data transmission is zero on both website on cloud server and dedicated server, throughput of website on cloud server is higher than website on dedicated server, request service per second of website on cloud server is higher than website on dedicated server and amount of concurrent user in the system of website on cloud server is higher than website on dedicated server.","PeriodicalId":306512,"journal":{"name":"2014 International Electrical Engineering Congress (iEECON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121242734","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 random signal source is a new signum-based piecewise-linear chaotic map, which provides not only robust chaos against parameter changes but also symmetric bifurcation for zero-thresholding for digital random-bit generation. Chaos dynamics are described in terms of equilibrium and Jacobian analysis, bifurcation diagram, Lyapunov exponent, time-and frequency domain signal, and cobweb plots. Autocorrelation, histogram, and NIST standard tests suite have been realized for statistical analysis of randomness of binary sequence, and the sufficient length of 1,000,000 bits successfully passed all NIST standard tests.

We aim at developing a safety system to support the aged people. Toilet danger detection system (TDDS) is a part of the safety system, which detects the danger and announces the information to outside people. Toilet is a small place for special needs. If there is a dangerous zone in the toilet, it will be more dangerous for aged people than young people. Toilet danger detection system presented in this paper uses a camera to take the toilet photos and uses image processing technique to detect the dangers for aged people. To detect the people edge, the image processing module calculates the difference between the initial toilet photo without people and the taken photo with people. When people edge is located in the dangerous zone, the danger information will be sent. According to experimental results, the proposed system successfully detected the dangers.","PeriodicalId":306512,"journal":{"name":"2014 International Electrical Engineering Congress (iEECON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126464699","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 power system stabilizing controller designed without taking such uncertainties into account may not tolerate and fail to operate. This paper aim at the new robust control design of power oscillation damper (POD) equipped with the doubly-fed induction generator (DFIG) wind turbine. Without difficulty of mathematic modeling, the inverse output multiplicative perturbation is used to represent system uncertainties. The structure of POD is specified as a practical 2nd-order lead/lag compensator with single input. The POD parameters optimization problem is formulated considering the variation of tie-line power flows. The POD parameters are automatically tuned by firefly algorithm so that the damping performance and robustness can be achieved. Simulation results in IEEE 9 bus test system ensure that the proposed robust POD is superior to the conventional POD in terms of the damping performance and robustness.","PeriodicalId":306512,"journal":{"name":"2014 International Electrical Engineering Congress (iEECON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127507847","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}
