Application of the BLDC motors use rectified AC source to minimize battery usage. However, the use of BLDC motors and rectifying circuit causing poor power factor and facing harmonic problems. At rated power, BLDC motors have power factor about 0.58 while the current THD at 73%. These values are outside the permitted tolerance limits. This study aims to improve power factor and THD value of current caused by the operation of brushless DC motors using a SEPIC converter. Moreover, the purpose of this study is that the motor is able to operate at different levels of speed and various loads. The results of the simulation of the design have been made, the motors can respond to variations in the speed reference given to the good. The control circuit is also able to make the motor maintain pace with changes in the load every time. Power factor observed at source will rise until 0.99 at various speeds. In addition, the current THD has an average value of 2% at various speeds. Both of these parameters are within the tolerances allowed by the standard.","PeriodicalId":308504,"journal":{"name":"2017 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114554131","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}

By determining the precise position of RoI, a computer-based identification will be able to work more efficiently, to give a better contribution in system and to eliminate objects that may intrude overall process. In malaria disease, the existence of Plasmodium can be observed from patient's microscopic thin blood smear images. Having utilised the computer aided detection based on image processing, malaria disease can be detected earlier and more objective in order to support the final decision of paramedics. This study proposes a novel method to automatically determine the region of interest (RoI) on thin blood smear images for facilitating the process of Plasmodium parasite detection. The approach includes Otsu thresholding method, morphological operation and binary large object (BLOB) analysis. Evaluation results on 24 thin blood smear images show that the proposed method achieves the sensitivity and PPV rates of 87.5% and 75.7%, respectively. These successful results in automatically determine the RoI which contains the Plasmodium parasite indicate that the proposed method has a potential to be implemented in the development of a computer aided malaria detection system.","PeriodicalId":308504,"journal":{"name":"2017 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128558478","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 cause of such performance degradation is due to the occurrence of fault on the actuator. The occurrence of actuator fault on Robot Manipulator 2 DOF (Degree of Freedom) will make tracking of the robot shifted from its reference, cause signal deviation and enlarge overshoot. Estimation and compensation techniques can be a solution to this problem, but these techniques can only be done if the designed system is capable of generating residual signals. This signal is a comparison of the response signal between the actual system and the MRC response signal. This paper explains the design of an AFTC (Active Fault Tolerant Control) algorithm based MRC. When an actuator fault happened, it was estimated and compensated with Model Reference Control (MRC) using Proportional Integral Derivative (PID) based on Computed Torque Control (CTC) law. Simulation result shows that the designed system can compensate actuator fault with small error tracking error about 0.0068 rad and has time response less than 1s. It also reach minimum overshoot through 0.041 rad.","PeriodicalId":308504,"journal":{"name":"2017 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127081616","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}

Some of the communication systems use EH device as their energy source. However, EH also has a limitation that is shown in its characteristics as random arrival and scarce of energy. Both of limitation is very influencing the system performance and the number of transmitted data. As we know the more energy is harvested, the longer system can operate. Because of EH limitation, the system with EH device needs to adjust to get the maximal channel capacity. This paper proposes the cooperative communication system with modified decode and forward (DF) method and EH device as a source energy. The modified DF method incorporate adaptive modulation at relay node to transmit data to the destination node. To test the proposed system, in this paper, three different scenarios are simulated, i.e. the non cooperative communication system with EH device as source energy, the cooperative communication system with DF method but fixed modulation level and EH device as a source energy and the proposed system. The simulation result shows the channel capacity of the proposed system is better than two other scenarios.","PeriodicalId":308504,"journal":{"name":"2017 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132389490","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}
