The results from our prediction model will be useful for systems related to traffic information. We constructed a model which can achieve 92.1% of accuracy on prediction of the congestion condition in next 30 minutes. Then, we found that the accuracy on the results that change from the current state is unsatisfiable. Hence, we constructed a new model that can improve the accuracy on this portion of traffic data. Moreover, we propose a new performance measurement which can distinguish the results in more detail. The final results show that our approach can improve the accuracy over the former model.","PeriodicalId":123701,"journal":{"name":"The 8th Electrical Engineering/ Electronics, Computer, Telecommunications and Information Technology (ECTI) Association of Thailand - Conference 2011","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121630506","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 requirements for the power inverter include high peak power, low output harmonics, inexpensive circuit and low continuous power rating. In this paper, reducing the output harmonics of cascade H-bridge multilevel inverter for electric vehicle applications is proposed. Switching angles of switch devices are determined by selective harmonic elimination technique. So, the effect of low order harmonics are reduced, as a result the efficiency of system has improved. Moreover, the number of DC voltage sources that used in the proposed inverter is less than conventional multilevel inverters that leads to reduce the inverter costs. A fundamental frequency switching methods has been used for modulation of inverter and to produce a seven-level phase voltages. Simulation results on various conditions were carried out using PSCAD/EMTDC software.","PeriodicalId":123701,"journal":{"name":"The 8th Electrical Engineering/ Electronics, Computer, Telecommunications and Information Technology (ECTI) Association of Thailand - Conference 2011","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115849355","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 reason why this is called the ubiquitous processor is because it progresses the overall status of ubiquitous and processor techniques. Ubiquitous computing is really a leading edge trend of next generation information and communication technologies. One of the most promising solutions for ubiquitous computing is exploiting not higher speed but parallelism in advanced circuits. In order to do this, it is really worthwhile to exploit hardware parallelism. Actually, the basic organization of HCgorilla follows multicore and multiple pipelines. These are Java compatible media pipes and cipher pipes. While the cipher pipe has been so far built in only one hardware RNG (random number generators), the improved HCgorilla makes it to have two RNGs. The novelty of this study is to use them for double cipher, that is, the one for transposition cipher called RAC (random number addressing cryptography) and the other for a substitution cipher by data sealing. Various aspects of the improved HCgorilla are studied. Those are the alternatives to this design, internal architectures or algorithms, comparison results with conventional works, encryption/decryption performance, the benefits and costs of this approach, new knowledge to be drawn from this design. According to evaluation, the double cipher promises practically secure strength without any overhead.","PeriodicalId":123701,"journal":{"name":"The 8th Electrical Engineering/ Electronics, Computer, Telecommunications and Information Technology (ECTI) Association of Thailand - Conference 2011","volume":"903 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132470927","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 input of the inverter can be supplied from a normal DC bus or a split-link DC bus composed from two series capacitors. In case of split-link DC bus, neutral point of three phases is connected to the middle point of the series capacitors, and each phase current is controlled independently. When the DC bus is not split-link, phase current is determined by three phase switching states. In this paper, analysis of hysteresis current controlled three-wire and four-wire grid connected inverters are given. L filter is connected between the inverter and the grid to filter current. Two different topologies are analyzed in terms of DC-link voltage utilization, output current total harmonic distortion (THD) and switching frequency.

After irradiated leakage current at 40, 55 and 70 keV were decreased. Therefore, we explain the effect of the X-ray irradiated on diode because it can improve performance of diode. The 4 mm2 P-N junctions were fabricated by boron implantation process into phosphorus doped silicon wafer. The results show that the leakage current changes after exposed to the X-ray which indicated that the types of defect have been changed. The changes of these activation energies can be higher or lower than the result before X-ray exposure, which depends on type of defects. However, the results in this paper presented that the defects that caused by X-ray irradiation are manageable.","PeriodicalId":123701,"journal":{"name":"The 8th Electrical Engineering/ Electronics, Computer, Telecommunications and Information Technology (ECTI) Association of Thailand - Conference 2011","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134301478","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}

In this application, the multi-objective bees algorithm (MOBA) is developed for solving the multi-objective optimal power flow (MOOPF) problems on small and large scale power system. The objectives of MOOPF are to minimize the total fuel cost of generation, environmental pollution and power system loss by considering many constraints i.e. limits on generator real and reactive power outputs, bus voltages, transformer tap-setting and power flow of transmission lines. Proposed crowded selection mechanism and fuzzy mechanism techniques are added into selection process of proposed MOBA. Also, the algorithm based on fuzzy set theory is used to extract the best compromise solution. In order to prove the proposed MOBA method, the simulation result of weight aggregation is used for comparison. The standard IEEE-30 and IEEE-118 bus system is selected to test the algorithm. The result shows that Pareto front of proposed MOBA are diverse and well distributed. The proposed MOBA have good performance and efficiency to solve multi-objective optimal power flow.","PeriodicalId":123701,"journal":{"name":"The 8th Electrical Engineering/ Electronics, Computer, Telecommunications and Information Technology (ECTI) Association of Thailand - Conference 2011","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131627024","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}

We determinate the operating frequency equal to 4.0–4.8 GHz approximation. Then the inductive waveguide filters were implemented by using an aluminum material.
