The study was a descriptive and experimental research. The effectiveness was divided into two main parts. First, the scores from individual work and group work were graded while studying in the course. Second, pre-test and post-test results were used to test the students' progress. The findings revealed interesting results. Although the start-up of pre-test mean scores in PBBL was lower than traditional class, the PBBL post-test scores were higher than traditional class students. Nevertheless, the mean scores of individual work in PBBL class were significantly higher than traditional class. Similarly, the mean scores of PBBL group work were slightly higher than traditional class. Therefore, students of the PBBL class performed higher progress and more effective than traditional class in terms of both individual and group work.","PeriodicalId":273911,"journal":{"name":"2017 14th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117050061","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}

One of the useful resources in almost all smartphones is a MEMS-based accelerometer which can be used as a motion sensor. This paper considers its application in healthcare support especially as a posture-monitoring device for patients during rehabilitation period after undergoing hip arthroplasty. The accelerometer output can be used to estimate the hip joint angle when the smartphone position and orientation relative to human body is suitably arranged. The implementation procedure for this concept is explained here by the use of a single Android smartphone to detect the hip-joint angles that lead to improper postures and thus having risk of joint dislocation. The warning sound can then be given to the patient. In the experiments conducted, all angles measured were within the expected ranges and the warning sound was timely activated. It is an evidence that a single smartphone can be used as a convenient healthcare device for hip-joint angle detection. The limit of its classification efficiency is however limited to within 72.7% which is due to the wearing position and the number of units used.","PeriodicalId":273911,"journal":{"name":"2017 14th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129058022","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}

Electricity demand is significantly affected by non linear factors such as climatic condition, calendar and other seasonality have been widely reported in literature. This paper considers parsimonious forecasting models to explain the importance of meteorological parameters for the hourly electricity demand forecasting. Many researchers include only temperature as a major weather factor because it directly influences electricity demand, however other meteorological factors such as relative humidity, wind speed etc. are rarely included in literature. Therefore, the main purpose of this study is to investigate the impact of meteorological variability such as relative humidity, wind speed, solar radiation etc. for short term demand forecasting and analyzed it quantitatively. We demonstrate three different multiple linear models including auto-regressive moving average ARMA (2,6) models with and without some exogenous weather variables to compare the performances for Hokkaido Prefecture, Japan. We applied Bayesian approach to estimate the weight of each parameters with Gibbs sampling and results show overall improvement of mean absolute percentage error (MAPE) performance by 0.015%.","PeriodicalId":273911,"journal":{"name":"2017 14th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127048780","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}

Several papers have been examined design methods for simultaneous stabilizing controllers. However, no paper examines a design method for simultaneous stabilizing controllers which has robust servo characteristic for the step signal. Therefore, using the simultaneous stabilizing controller which is designed by previously proposed method, the output of the control system cannot follow the step reference input without steady state error when the plant has uncertainty. Moreover, the influence of the step disturbance cannot be attenuated. In this paper, we propose a design method for simultaneous stabilizing controllers which has robust servo characteristic for the step signal. They can simultaneously stabilize a pair of unstable plants having no common unstable poles. In order to solve this problem, we use the relationship between the simultaneous stabilization and the strong stabilization. Then this problem can be reduced to the strongly stabilization problem with interpolation problem. We can obtain the parameterization of all simultaneous stabilizing controllers with robust servo characteristic for the step signal by using this idea.","PeriodicalId":273911,"journal":{"name":"2017 14th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123644826","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}
