Providing information sources domain for information seeking agent from organizing knowledge 从组织知识出发,为信息搜索代理提供信息源域
Knowledge Istiadi, L. Nugroho, P. Santosa
This paper proposes a tracking mechanism to obtain the information sources that are stored on the personal knowledge organization which will be used to direct the search of information on the Internet by a software agent. Semantic representation of the organizer is viewed as a map of the information sources that are classified hierarchically based on the scopes of knowledge domains from the standpoint of the agent. The tracking mechanism by query will look for the information sources in the knowledge domains based on the same scope of a defined knowledge domain. This tracking will produce a list of information sources that will be followed to get the domain location as internet access preferences.

Falahah, Defrin Karisia Ayuningtias
The implementation of GIS based application is growing rapidly in many areas such as business, government, or public services. Potential implementation of a GIS-based application then applied to the mapping of conditions and irrigation building and canal. The application will display the latest information on the condition of each building irrigation in Rentang area, covering three districts namely Majalengka, Cirebon and Indramayu. This area has about 1000 buildings irrigation and segment that connects between buildings. In order to present the interactive map and running in a web environment, the map should be processed using a series of stages of preparation of maps using GIS software such as ArcGIS, Quantum GIS, PosgreSQL and PostGIS, GeoServer, and OpenLayers. The resulting map is then divided into three main layers based on category object to be displayed, that is the main irrigation channel, secondary channel and tapping buildings. Users can see the position and condition of each object which is represented by a different color for each condition: green for good conditions, yellow for minor damage and red for major damage. This application is expected to help the units involved in obtaining a general overview of irrigation in certain areas quickly and accurately.

R. S. Darwis, Suwadi, Wirawan, Endroyono, T. Suryani, P. H. Mukti
In this paper, an implementation of MIMO 2×2 system using Alamouti algorithm on Wireless Open Access Research Platform (WARP) is presented. The performance of the proposed system is evaluated in terms of Bit-error-rate (BER) for different environments that are indoor and outdoor which of each have Line-of-Sight (LOS) and non-Line-of-sight (NLOS) conditions. Afterwards, in order to validate the capability of the proposed system, SISO and MISO systems are also implemented. By an experimental analysis, MIMO system with NLOS condition in both indoor and outdoor environments show better performance than MISO and SISO. Meanwhile, for the conditions of LOS in both indoor and outdoor environment, the performance of SISO system is better than MIMO and MISO. In the case of NLOS conditions, the performance of proposed system is also examined and compared in the both environments. In indoor environment, at transmit power -21.48 dBm, MIMO, MISO and SISO systems have BER value of each of 1.172×10-4, 1.146×10-1, and 0.2551, respectively. Finally, in outdoor environment, at transmit power -25 dBm, MIMO system achieves BER of 0 better than MISO and SISO which achieves BER of 3.1×10-3 and 0.21, respectively.

Some activity in our daily life is prone to have some accidents, such as falls. Falls can make people in fatal conditions, even death. A prototype of fall detection system using accelerometer and gyroscope based on smartphone is presented in this paper. Accelerometer and gyroscope sensors are embedded in smartphone to get the result of fall detection more accurately. Automatic call as an alert will be sent to family members if someone using this application in fatal condition and need some help. This research also can distinguish condition of people between falls and activity daily living. Several scenarios were used in these experiments. The result showed that the proposed system could successfully record level of accuracy of the fall detection system till 93.3% in activity daily living and error detected of fall was 2%.","PeriodicalId":404830,"journal":{"name":"2014 The 1st International Conference on Information Technology, Computer, and Electrical Engineering","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132429407","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}

Design and simulation of Neural Network Predictive Controller pitch-angle in permanent magnetic synchronous generator wind turbine variable pitch system 永磁同步风力发电机组变桨距系统中神经网络预测控制器的设计与仿真
Suyanto, Soedibyo, Aji Akbar Firdaus
This paper considered maximum power extraction in wind turbines. However, the importance of constant power output of a wind turbine is increasing as the contribution of wind energy to the distribution network / grid grows. This may be considered as a guide of the future pitch angle control problems. The permanent magnetic synchrounous generator (PMSG) wind turbine variable pitch system is done through changing the electrical characteristics of the generator and changing the pitch angle. Also PMSG wind turbine variable pitch system is equipped with systems for regulating the orientation angles of the axis of the turbine against the wind and against the skyline. The design and simulation of Neural Network Predictive Controller (NNPC)-pitch angle involved in PMSG wind turbine variable pitch system is outlined. Its performance design is simulated to baseline linear controller through simulation in the range of wind speed is 7- 10 m/s. To test the designed NNPC-pitch angle performance, PMSG wind turbine variable pitch system has been simulated and results are constant power output.
本文研究了风力发电机组的最大功率提取问题。然而,随着风能对配电网的贡献越来越大,风力发电机稳定输出功率的重要性也在增加。这对今后的俯仰角控制问题有一定的指导意义。永磁同步发电机(PMSG)风力发电机组变桨距系统是通过改变发电机的电气特性和改变桨距角来实现的。此外,PMSG风力涡轮机可变螺距系统还配备了用于调节涡轮机轴线对风和对天际线的方向角的系统。概述了PMSG风力发电机组变桨距系统中神经网络预测控制器(NNPC)-桨距角的设计与仿真。在风速为7 ~ 10m /s的范围内,对基线线性控制器的性能设计进行了仿真。为了验证所设计的nnpc -俯仰角性能,对PMSG风力发电机组变俯仰角系统进行了仿真,结果表明该系统的输出功率是恒定的。
