Finite element method magnetic (FEMM 4.2) tool is employed to determine and analyze the cogging torque. It can be proved that by mixing of slot opening reduction and permanent magnet shaping at a particular shoe height can diminish the cogging torque of Inset-Permanent Magnet Generator sharply.","PeriodicalId":149318,"journal":{"name":"2018 International Conference on Electrical Engineering and Computer Science (ICECOS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124274243","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 have chosen Counter-Strike: Global Offensive (CS:GO) as the benchmark in this study. Many data from official CS:GO tournaments and public match are collected for the analysis, whereas game refinement measure is employed for the assessment with a focus on two aspects: gameplay and rounds system. The results show that the gameplay aspect has lower game refinement, i.e., the game is highly skillful, whereas the rounds system aspect has higher game refinement, i.e., the game is highly stochastic. The combination of the two aspects successfully balances the skillfulness and chance, which results in their popularity. In addition, since their release, CS: GO has sold more than 40 million game copies, awarded as “Best eSports Game of The Year” and updated maps and successfully maintain the game balance of the maps, as measured by game refinement.","PeriodicalId":149318,"journal":{"name":"2018 International Conference on Electrical Engineering and Computer Science (ICECOS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125209559","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 data used is Data warehouse UNSRI of development project. From the value of automated estimation result by MRE system equal to 1.735888282 with effort value equal to 20.97, it can be concluded that the error value generated is big enough (above zero). This measurement suggests that price estimated by software engineering techniques, especially software cost estimates using analogy modification methods, are significantly different from the actual field price or pricing. After the observation between the approximate price and the actual price offered in the field, it can be stated that the price of data warehouse in the field is highly valued at low.

Many techniques had been used such as time domain analysis, frequency analysis, power spectrum density, wavelet analysis, high-speed camera analysis, VHF interferometer technique, X-ray radiation and the list goes on. It was found that a lot of researchers suggest to interpret CPTs as a types of pulse activity produced during the dart leader activities of subsequent leaders or the superposition of a few regular pulse train produced by dart leader activities. There are several previous studies in both regular and chaotic pulse trains agreed with this suggestion. The characteristic of chaotic pulse trains had also been reviewed in this study. Some authors suggest that when a “chaotic” component is observed during the subsequent leader activities, high frequency intensity would increase. It is also suggested that the downward dart leader gets a lot of luminosity when it goes together with chaotic pulse trains. The speed of the subsequent leaders (associated with CPTs) had also been discussed in this paper. The power spectrum density may be one of the methods to identify CPTs from another subsequent leaders. Several hypotheses on the origin of the CPTs were proposed. More research and analyses should be done in the future in order to clarify the physical phenomena behind chaotic pulse trains occur in between return strokes or in between cloud flashes.","PeriodicalId":149318,"journal":{"name":"2018 International Conference on Electrical Engineering and Computer Science (ICECOS)","volume":"351 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115975667","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}

It is important to note here that all previous studies were using only broadband E-field antenna system. In this study, the evaluation of existence of IB process was done based on both broadband E-field and B-field antenna systems. The data of lightning flashes were collected on June 3rd 2016 by our station in Malacca, Malaysia. We analyzed 50 CG flashes from a tropical storm happened in Kuala Lumpur area. The data recorded by broadband E-field antenna system shows that 94% of CG flashes were preceded by IB process. On the other hand, by using B-field antenna system, all CG flashes have been observed to be preceded by IB process. This finding is very significant because we can conclude that all CG flashes are initiated by IB process.

The resistivity and permittivity were determined using equations proposed by Sundae and Dwight and the frequency dependence properties were modelled according to Scott‘s model. It was found that the voltage response was highly affected by the frequency, especially at high soil resistivity of 1000 $Omega{m}$ and above (up to 4% decrease in voltage response). As for the low soil resistivity cases, the voltage response was less affected by the frequency, which is 1.4% and 1% lower for soil resistivity of 100 $Omega{m}$ and 10 $Omega{m}$ respectively. Obviously, the current circuit-based model (frequency independent model) tends to provide overestimated results. Therefore, the effect of frequency on the soil resistivity and relative permittivity should not be neglected when determining the transient performance of grounding electrode in order to obtain accurate results.","PeriodicalId":149318,"journal":{"name":"2018 International Conference on Electrical Engineering and Computer Science (ICECOS)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133233306","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}
