The proposed controller has robustness against uncertainties of dynamic parameters. The control law provides robustness against disturbances with unknown bounds. To investigate the performance of the proposed control method, simulations are conducted for a nonlinear upper-limb exoskeleton comparing with a computed torque control method. STM32F4Discovery was implemented as the main controller either a traditional controller or a sliding mode control. In the experiment, trajectory tracking in joint space were conducted to evaluate the performance of the developed robot and the controller. Experimental results show that the robot can effectively track the desired S-curve trajectories corresponding to passive arm movement.","PeriodicalId":188870,"journal":{"name":"2020 9th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116487352","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}

Building members are assumed to be delivered out of the affected area in an unprocessed state and processed during the delivery plan. Therefore, it is necessary to consider the changes in minimum delivery unit constraints. This study formulated three delivery strategies, including a collaborative strategy, to minimize delays in delivery. Comparing each strategy using numerical experiments, it was shown that the use of a secondary storage facility with processing capability is most effective in reducing delays in delivery. In addition, it was shown that the use of planned transshipment, one of the collaborative strategies, can reduce delivery delays without using additional equipment.","PeriodicalId":188870,"journal":{"name":"2020 9th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128026978","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}

To support the actions of teachers to improve lessons and teaching materials, we analyzed the operation logs of students using our Fill-in Workbook System in multiple lessons. The transition of learning attitudes for each lesson and for each time / each slide in the lesson for the entire class is extracted. In addition, to support the student's retrospective review of the lessons, the transition in the attitude of each student to the class is extracted. The results confirmed that lessons in which the class attitude became worse could be detected by analyzing the system focus time and the degree of synchronization between the page explained by the teacher and the page referenced by the student, and that the difference in learning attitudes increased when there were few blanks. In addition, we analyzed the degree of asynchrony (jumping ahead, falling behind) with the teacher's explanation and clarified the relationship between the time taken to explain one page and learning attitude. Furthermore, it was confirmed that the student's individual learning state could be divided into three separate conditions.","PeriodicalId":188870,"journal":{"name":"2020 9th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128122651","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 script in a Wiki page of the Wiki server controls an agent bot or an analyzing bot. An agent bot is placed between a LAN and its gateway. It can capture every packet between hosts in the LAN and hosts behind the gateway from the LAN. An analyzing bot can be placed anywhere in the LAN or WAN if it can communicate with the Wiki server for controlling the analyzing bot. The analyzing bot has R statistical computing system and it can analyze data which is collected by agent bots.","PeriodicalId":188870,"journal":{"name":"2020 9th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126002597","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 addition, an analysis of learning activities using LMS learning records has been attempted by many educational institutions. In this paper, we analyzed students' learning activities and learning effects by using basic log data from an LMS on blended information literacy lectures to evaluate the lectures. In addition, we divided students into groups and analyzed their differences by the number of learning effects and learning activities. Additionally, in order to confirm which teaching materials were useful, this paper compared each group’s usage of teaching materials and conducted a questionnaire with the students about lecture contents and teaching materials. As a result, we saw that there were variations in the use of teaching materials even among students with many learning activities. We report the details of these differences and make suggestions for improving lectures.","PeriodicalId":188870,"journal":{"name":"2020 9th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127972201","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}
