Two intelligent approaches have been employed. Fuzzy is used to adjust the set-point and, while PSO is utilized to optimize the objective function after setting by Fuzzy. Moreover, Fuzzy is also utilized to adjust weighting factors in order to find the best values for the PSO local and global. This will improve PSO performance. The proposed method was combined two levels as Fuzzified PSO, and the model has been simulated and validated by a real case study which consists of 5 electric-driven chillers. The results have shown that the effectiveness of the proposed method compared to the conventional one, and it also has demonstrated a better power saving.","PeriodicalId":247287,"journal":{"name":"2016 6th International Conference on Intelligent and Advanced Systems (ICIAS)","volume":"356 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115934092","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 phase-shifted full bridge PWM dc-dc converter is widely used in high power, high voltage applications due to the advantages of high power handling capability with low switching and conduction losses. The phase shift feature of the control signal allows ZVS thereby eliminating the switching losses during FET device transition. It also minimize the parasitic effect and conduction losses at high frequency operation thereby increase system efficiency. A 3kW, 100 kHz high frequency phase-shifted full bridge converter was design and simulated in Matlab/Simulink to analyze the system performance prior to experimental implantation. The converter is intended for hybrid energy systems (HES) application in which a state space controller will be developed with wider dynamics to accommodate variable input sources mostly from renewable energy resources like solar and wind power. The converter simulation results shows that the system achieved greater than 90% efficiency at full load current.","PeriodicalId":247287,"journal":{"name":"2016 6th International Conference on Intelligent and Advanced Systems (ICIAS)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122850154","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}

They can be used to detect biomarkers in exhaled breath (EB) for screening of diseases. Damping is believed to hinder the performance of these resonators. This paper focuses on investigating effects of damping in natural frequency, mass sensitivity and displacement of a proposed resonator for biomarker detection in EB. The resonator is electrostatically actuated using parallel plate capacitor principle. Squeeze film damping was found to affect the resonator performance when the gap distance between the plates was varied as 5, 7, 9, 10 and 11 μm, in which 5 μm led the resonator to be overdamped. For the rest of gaps the resonator is underdamped.

The structure of 360° twisted helical capacitance sensor had been designed, analyzed and optimized using finite element method. A sinusoidal function was observed as the relationship between the capacitance readings and holdup. As the nonhomogeneity in the distribution of capacitance sensitivity field cannot be completely eliminated, a helical capacitance sensor was designed in such a way that a sinusoidal relationship was generated. The numerical readings and the approximation model obtained a very close agreement, where the mean absolute difference was about ±1%. Besides, the effects of geometric parameters on the capacitance values were analyzed and investigated, where it was found that the symmetry of sinusoidal function can be modeled by adjusting the pitch of helix.","PeriodicalId":247287,"journal":{"name":"2016 6th International Conference on Intelligent and Advanced Systems (ICIAS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128993910","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}

A sample of 20 healthy participants was recruited and exposed to 10 minutes animated learning contents. After 30 minutes of the learning session, they performed a memory recall task; the correct and incorrect responses in recall task were recorded for computing the memory performance. EEG amplitude asymmetry was computed for six frequency band (delta, theta, alpha, beta, high beta, and gamma) and the correlation was checked with the memory recall. It was found that the EEG delta asymmetry correlated negatively (r=0.44−0.68; p-value<0.05) with the semantic memory recall in the right hemisphere (RH) more than left hemisphere (LH). In another hand EEG gamma asymmetry was also correlated negatively with the semantic memory recall (r=0.45−0.79; p-value <0.05) in RH more than LH. A positive correlation also was found in delta and gamma (r=0.47–0.56; p<0.05) these results suggested that the right hemisphere during semantic memory recall has high dynamic activity more than left hemisphere.","PeriodicalId":247287,"journal":{"name":"2016 6th International Conference on Intelligent and Advanced Systems (ICIAS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127807527","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 bare-metal embedded code developed for this application achieves the required timing constraints through efficient use of flexible memory organization, timer interrupts and CPU resource sharing. The developed system has been functionally verified to autonomously control the intended UAV in the desired manner through extensive real-time Hardware-In-Loop (HIL) simulations.

Automobile industry has been rapidly switching to high power LED front lighting systems as they perform better in terms of luminous flux and energy efficiency than the conventional ones. However, due to the electrical characteristics of LEDs these systems cannot be powered directly from the automobile battery. They require specialized driving circuits which can respond to the changing needs of the LEDs as their electrical properties change while maintaining the uniform brightness. So far, DC-DC switching power converters offer the easiest way to power high power LEDs and control their luminance. A switching power converter consists of a power stage and a compensation circuit. The power stage includes switches and output filter, it only performs the basic power conversion from the input voltage to the output voltage. The paper discusses the boost power stage design only and does not cover compensation network. A detailed discussion on selecting power stage component requirement is presented. MATLAB/Simulink is applied to execute the whole circuit simulation to verify the theoretical predictions hence to provide a useful guide for design engineers and researchers.","PeriodicalId":247287,"journal":{"name":"2016 6th International Conference on Intelligent and Advanced Systems (ICIAS)","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125918223","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}
