Real-time applications such as videoconferencing, is the most prioritized service to get a QoS guaranteed in the network. So it is important to provide QoS guarantees for applications that are sensitive to delay and jitter. In this study, writer try to evaluate in detail the readiness of existing IP networks to support desktop videoconferencing services H.323 point-to-point calls for a session capacity that can be supported based on bandwidth and delay bounds that occur in the network for voice and video services. As well as evaluating several methods commonly used queuing disciplines, such as first-in-first-out (FIFO), priority queuing (PQ), weighted fair queuing (WFQ), as well as WFQ queuing algorithm based differentiated service code point (DSCP) with random early detection (RED) to get the best QoS performance values using OPNET IT Guru. Simulation results show the number of videoconferencing sessions that can be supported more determined by the bandwidth instead of end-to-end delay, which can support 63 calls. But when the final accuracy check performed by generating 63 calls simultaneously, there was a considerable mismatch between video and voice packets sent and received. Simulation success by generating 45 calls simultaneously. The generation of 45 calls simultaneously indicate good health network where there is no packet loss, and end-to-end delay around 5.8 ms and adequate utilization for routers, switches, and links. WFQ_DSCP method provide the best value, especially in the number of packets dropped, and ratio of packet sent and received against time among the other methods.","PeriodicalId":230688,"journal":{"name":"2014 Electrical Power, Electronics, Communicatons, Control and Informatics Seminar (EECCIS)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115674474","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 testing is done by measuring the illuminance (the unit is lux) with luxmeter on the measurement zone which has certain measurement points. The LED lights on Pattimura street have power of 237 watt, light distance of 50 meter, pole height of 9 meter, and street width of 6.9 meter. The testing result shows that the lighting on street surface is SNI compliant, which means the LED light can be used for street lighting. But there is high illuminance on measuring point which is perpendicular to light and it means light pollution. On the contrary the illuminance decreases significantly on the zone between the light pole and it is not SNI compliant. For this reason, the distance between light pole and the light power should be decreased. The result also has the isolux drawing and it is designed with Dialux software. The branches of trees on both streets cover the light so that the illuminance of street surface decreases. And this matter should be handled by DKI Jakarta government.","PeriodicalId":230688,"journal":{"name":"2014 Electrical Power, Electronics, Communicatons, Control and Informatics Seminar (EECCIS)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127240850","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}

A prominent textile industry currently employs obsolete yarn twist testers in its quality control laboratory to check yarn performance. However, the twist mechanism part is mostly intact. The purpose of the research is to restore and improve the function of the old yarn twist tester by replacing conventional control system with the microcontroller based - one. The newly designed tester is able to directly display the twist level and transmit the measurement data to PC via RS232 link. An application program on PC also provided to facilitate data analysis and storage. The system consists of main controller and twist mechanism. The primary task of the main controller is to control the twist mechanism to perform tpi measurement of the yarn sample. The MOSFET driver in H-bridge arrangement is employed to control the speed and direction of the motor using PWM method. The main controller also incorporates serial EEPROM and RTC to hold twist per inch (tpi) measurement data temporarily and to provide time stamp respectively. Interaction between user and the system is made possible matrix keypad and character LCD. The twist mechanism is used to perform untwist/twist action. It consists of a dc motor, a rotary encoder, a Hall-effect sensor, an opto - interrupter, and miscellaneous mechanical parts. Featuring 4 selectable speed setting, the final design has capability to measure number of twist of both Z- and S-twist yarn with error less than ± 1 tpi. Basic summary statistics provided by GUI includes number of sample, sample minimum, maximum, average, and standard deviation.","PeriodicalId":230688,"journal":{"name":"2014 Electrical Power, Electronics, Communicatons, Control and Informatics Seminar (EECCIS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133087800","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 performance of the control system in addition with the neural network learning scheme are depict in this paper. The complete schemes of both conventional and proposed scheme are simulated using Mathlab. The comparison system performance between the conventional direct torque control and the proposed intelligent neural network speed control have been investigated and show a satisfy result in both steady state and transient response.

This research method begins with the collection of primary data, the direct measurement of natural wind speed and exhaust airflow velocity. Secondary data is mainly drawn from the data specification wind turbine selected unit. Subsequent calculation of the relevant variables, such as: electrical power, electrical energy and power coefficient of the rotor. Analysis and discussion focused on finding interplay between measurable variables. From the research, it can be concluded: (a) Exhaust air flow rate contained in the research area, starting a low of 3.92 m/s which is located at a point 15 meters from the source to a high wind reaches 19, 88 m/s which is at a point 3 feet from wind sources. (b) The amount of exhaust air flow rate has a significant effect on the power and potential of electrical energy that can be generated by a wind turbine mini scale, (c) The most important factors that influence the selection of a wind turbine in WECS is the air flow velocity at the local site and rotor power coefficient of each alternative wind turbine. The higher the coefficient of the rotor of a wind turbine, the higher the efficiency of the wind turbine, and (d) The potential airflow considerable waste has yet to be directly used as WECS, but first must be adjusted for the height of the exhaust pipes to achieve the required height.","PeriodicalId":230688,"journal":{"name":"2014 Electrical Power, Electronics, Communicatons, Control and Informatics Seminar (EECCIS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130530780","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}
