To meet this increasing demand, the power transferred should also increase. However, the existing EHV transmission lines cannot be loaded up to their thermal limits because of the considerations of their transient stability. To address this issue simultaneous power transfer scheme came into existence. With this scheme it is possible to load the transmission lines close to their thermal limits, thus increasing the power transfer capacity of the line. This is done by the transferring AC power with DC current superimposed on it. A double circuit line is converted into composite AC-DC line which will be used for simultaneous AC-DC transmission. In this work, simple mathematical model of composite line is developed and analysed to track down the conditions for maximum power transfer. Developed mathematical approach is also compared with the existing graphical method for calculating maximum power transfer. The results obtained from mathematical model are found to be in close proximity to those obtained by graphical analysis.","PeriodicalId":6528,"journal":{"name":"2017 International Conference on Electrical Engineering and Computer Science (ICECOS)","volume":"94 1","pages":"328-332"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85100642","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 order to provide the analytical tool for the agricultural commodities data, this study aims to develop a Spatial Online Analytical Processing (SOLAP) that is integrated to spatial data warehouse. The SOLAP for Agricultural Commodities adopts the three-tier architecture. The first layer is the visualization layer which is responsible for displaying data summary in tabular format, graphics, and maps. This layer consists of OpenLayers, GeoJSON, HTML and Java Script. The second layer is the logic layer which is responsible for receiving input parameters from the visualization layer, retrieving data according to parameters to the data layer, processing data, then returning the data to the visualization layer. The logic layer uses PHP as the programming language and CakePhp framework. The third layer is the data layer which is the agricultural commodities data storage. This layer consists of OLAP engine Mondrian and PostgreSQL. The SOLAP for Agricultural Commodities has successfully implemented and can provide the summary of agricultural commodities data in tabular format and maps.","PeriodicalId":6528,"journal":{"name":"2017 International Conference on Electrical Engineering and Computer Science (ICECOS)","volume":"48 1","pages":"167-170"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81707600","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 test image obtained from the results of capturing of the camera to the object of the form of tubes, balls, cubes, and 2D images. This research is the early step in the development of the ability of a computer vision to be able to mimic the performance of eye organs in humans in detecting an object. The detection step of the proposed method begins by determining the feature point on the image of the taking results of two cameras using the Harris Corner Detector. After the feature point of the two images obtained, then performed tracking feature point using the Lucas-Kanade Tracker method. In this research, the distance between the cameras used 10, 20, and 50 cm. The Effectiveness of the detection result of the proposed method is measured using the recall and precision parameter values obtained in the merged of the image. The proposed method gives a Recall value above 90% and a precision value above 50% for a distance of the cameras 10cm and 20cm for ball and tube objects. In the box object, the Recall value is 60% for a distance between the cameras 50cm and below 25% for a distance of the cameras 10cm and 20cm. The precision value for detection of the box object is very low, i.e. less than 25%.","PeriodicalId":6528,"journal":{"name":"2017 International Conference on Electrical Engineering and Computer Science (ICECOS)","volume":"15 1","pages":"163-166"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80266485","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 common issue comes from customers that always need excellent services. On the other hand, there are employees acting as an internal element of enterprise who need to be motivated while delivering the services. It has been known that the pressure at work and employees' personal problem can cause negative impacts such as decreasing the productivity and lack of teamwork. Moreover, IT managers have a limitation in understanding the psychological issues. Hence, it drives the enterprise to adopt an approach, which can help IT managers to motivate and reward the employees. They also need to ensure the employees that enterprise can be trusted, which means they should not be any doubt in helping the enterprise to reach the goals. Gamification is one of the persuasive approaches that have been used to boost motivation. In previous research, the design of user-centric ITIL function, which embedded gamification approach has been designed. But, the design still required evaluation in order to reveal the positive correlation between the user engagement and system success.

D2D communication allows direct communication between two or more devices such as mobile user equipments without any base station help as a relay. However, enabling D2D features in cellular communication network will reveal more complex interference problems, because D2D communication could share the same frequency resources as its underlain cellular communication network. This paper analyzes the interference problems in such D2D communications underlying cellular communication network for downlink transmission. This paper explores the use of power control methods to reduce the effect of interference. The decision whether to increase or to decrease the power level on base station (evolved Node B/eNB in Fourth Generation/4G Cellular Networks) or on the transmitter of D2D pair (Transmitter of D2D User Equipment/TUE) is based on the estimated current Signal to Interference plus Noise Ratio (SINR). First method of power control (PC-1) uses a fixed value to control the power level of the transmitter. Another one (PC-2) uses moving average of interference power values. The simulation was carried out to evaluate those two power control methods and its results in term of Cumulative Distribution Function (CDF) of SINR are compared to the system without power control method. The simulation results show that both power control methods contribute the improvement of performances; for one cellular equipment (CUE) and 100 pairs of D2D it achieved the improvement of SINR distribution at 5% with PC-1 and at 4% with PC-2 compared to the system without powr control, meanwhile for 1 D2D pair and 100 CUEs the CDF of SINR at 0 dB achieves 40%, 3%, and 0% for the systems without power control, with PC-1, and PC-2 methods, accordingly.","PeriodicalId":6528,"journal":{"name":"2017 International Conference on Electrical Engineering and Computer Science (ICECOS)","volume":"70 1","pages":"28-32"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74001892","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}
