There are practical difficulties in the control design of CMG. First, friction occurs on the rotation axis of CMG. Second, CMG is a nonlinear system. Third, there are uncertainties in the mathematical model of CMG. In this study, those practical difficulties are solved. The controller is designed to compensate the friction. The controller has the integrator for the error between state and reference to eliminate steady-state error. There are trigonometric functions of a state variable in the mathematical model of CMG. In this study, the trigonometric function is approximated more exactly by not first-order but third-order Taylor series expansion. The mathematical model involving those high order terms is represented as the equivalent first-order system by using descriptor representation and linear fractional transformation (LFT). The robust stability for the system with those trigonometric functions is guaranteed by using polytopic representation based on Linear Matrix Inequalities (LMIs). The moment of inertia has one of the uncertainties in the mathematical model. It is treated as the uncertain parameter in this study. The robust stability for the system with the uncertainty is guaranteed by using polytopic representation based on LMIs. The effectiveness of the proposed controller is illustrated by simulations.","PeriodicalId":207985,"journal":{"name":"2015 7th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114175553","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 college graduates are highly evaluated from the industrial world for over 50 years. In order for the students to acquire high skills, the curriculum in NIT should be combined lectures with experiments and/or practical trainings. However the skills of experiments and practical trainings are implicit know-how up to now. Therefore, we make the skills be explicit knowledge for improvement of skills. In this paper, we propose a method to visualize the skills, and we introduce an approach to decide the level of achievement of experiments and practical training skills. This approach is almost based on original lab manuals, but in order to evaluate of ICT and Software skills, we attempt to use \"i Competency Dictionary\". In order to propose our methods, we checked and evaluated over 300 lab manuals. The experimental skill-sheets and the evaluation-sheets that are the vital part of our methods, have been developed using the learning items, which derived from those manuals in manually. It is possible to visualize each student's skills by defining evaluation standard with the sheets. The evaluation standard is one of the tools to guide students to their final target effectively and clearly. Using our methods, the level of achievement and the motivation of students' skills will be improved drastically in the experimental subjects and practical trainings.","PeriodicalId":207985,"journal":{"name":"2015 7th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123735183","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 paper, we start by mainly focusing on the first step of our framework, selecting potential influencers based on their association with a particular stock market. With numerous limitations of Twitter service to access and acquire Twitters data, a new methodology is also proposed to use a List feature to select potential financial influencers. It requires only Lists of accounts that contain an official Twitter account of the specific financial market, provided by Twitter's users, through Twitter API. Our methodology is designed to use only a small amount of data, by which it can be practically used under the limitation of Twitter API's crawling rate. Experimental results show that most of the potential influencers returned by our methodology are similar and related to the specific financial markets, which are companies listed on S&P 500 in this experiment. Most of the returned influencers are the official accounts of company or organization from the same sector and news media with a special emphasis on the same industry. Comparing to Twitter's user recommendation service (Who-To-Follow) and a crowdsourcing search for topic experts (Cognos), our methodology returns more related accounts in both percentage and the number.","PeriodicalId":207985,"journal":{"name":"2015 7th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114212943","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}
