Frequency and voltage drifts can be minimized and kept within tolerable limits by automatic generation control. Automatic generation control of a system consists of two parts; load frequency control (LFC) and automatic voltage regulator (AVR). In this paper, a simulation study is carried out to understand the operation of load frequency controller by developing models in SIMULINK. The simulation study helps students to understand the principle and challenges behind load frequency controller.","PeriodicalId":265555,"journal":{"name":"2012 IEEE Global Humanitarian Technology Conference","volume":"903 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116400145","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 Kalman filter is an efficient recursive filter that estimates the state of a dynamic system from a series of noisy measurements in the Total Power Generation (TPG). ED is an example of a dynamic system algorithm that has been widely used for determination most economical generation profile to optimize the overall electricity prices. ED is a non-smooth problem when valve-point effects of generation units are considered. This paper applies Kalman - Particle filter (KF-PF) to the ED state estimation problem that has been optimized with Particle Swarm Optimization (PSO), with the emphasis to avoid the solution being trapped in local optimas [1], [2]. Kalman and particle filter are used to estimate TPG as state of ED problem. The performance of the KF-PF has been tested on a typical system and compared with others proposed in the literatures. The comparison results show that the efficiency of proposed approach can reach higher quality solutions.","PeriodicalId":265555,"journal":{"name":"2012 IEEE Global Humanitarian Technology Conference","volume":"331 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116456795","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}

CIAN is a self-contained medical clinic built in a shipping container and deployed, ready for use, anywhere in the world to provide an emergency healthcare infrastructure. Telemedicine is used to deliver healthcare and share medical knowledge over a distance using telecommunication and information technology. We describe a design of a telecommunications system that facilitates the operation of the telemedicine network in Kajokeji county by connecting all local Primary Health Care Units (PHCU) to the Clinic-In-A-Can and to the regional hospital in Juba, the capital city of South Sudan. The model includes a web based telemedicine system, which provides basic services for medical tele-consultation via both audio and video conferencing. The system will be used to facilitate the communications between nurse and physicians; community health worker (CHW) and nurse; physician to patient. We include a database design to store computerized medical records. This relational database will be used by healthcare providers to store, retrieve and update patient information, generate referrals, and provide feedback to referrals through a Graphic User Interface (GUI).","PeriodicalId":265555,"journal":{"name":"2012 IEEE Global Humanitarian Technology Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124937708","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}

However, smallholders face significant challenges, often due to a lack of access to information about prices and markets. This paper describes ongoing work on a methodological approach for addressing these challenges through the use of an Android-based mobile-cellular platform application. Using a social networking approach, the application enables smallholders to interact with traders, retailers, consumers, and each other in such a way as to encourage the emergence of sustainable and fair regional markets. It will increase profitability by providing information on price and demand, and enable better cooperation and knowledge-sharing between farmers. This may not only improve yields, but also increase diversity in agricultural products produced: farmers can better adapt to changing climatic conditions and be less vulnerable to volatile commodity prices.","PeriodicalId":265555,"journal":{"name":"2012 IEEE Global Humanitarian Technology Conference","volume":"139 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126807734","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}

It may become weak or lose its validity as a result of improper changes or attention and the way of thinking which could be due to overshadowing influences. The effect of such changes and influence has continued to cause problems in the key aspect of global well-being of the people for years. The application of technology in enhancing human capability for the purpose of reducing suffering and promoting the well-being of humanity through humanitarian activities will help secure and guarantee the lives and properties of displaced in the crisis regions. Therefore the humanitarian organizations and government agencies will have to depend on the application of technology in making quick and steady reliefs to the vulnerable regions easier. Technology has revolutionized global communication networks, empowering individuals and communities in even the most inaccessible of places. As the humanitarian community works toward improving coordination and collaboration to respond to an ever-growing number of humanitarian emergencies while seeking to improve evidence-based practice, the need for real time data acquisition, communication, and management for effective response is more acutely recognized. As technologies enter the humanitarian space they confront the everlasting challenge of balancing utility, efficiency, and feasibility among its multiple beneficiaries. This paper therefore traces the humanitarian challenges and opportunities and suggests a way forward for the benefit of humanity.","PeriodicalId":265555,"journal":{"name":"2012 IEEE Global Humanitarian Technology Conference","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133427254","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 semi-official FOSS initiatives were undertaken in 2003 when the Taiwanese government set up OSSACC (Open Source Software Application Consulting Centre) to promote FOSS on campuses. In these 10 years, FOSS on campuses has begun to find its local meanings and grasp teachers' and students' attention. The purpose of this paper is to investigate FOSS on campuses in Taiwan in terms of its development, its local significances and the difficulties encountered in promotion, in the hope of providing an understanding and interpretation of FOSS in the context of education. The results indicate that the majority of teachers and students do not recognize or identify with the cultural values embedded in FOSS but use it as a tool to solve educational problems. In order to promote the use of FOSS on campuses, efforts are needed to address the difficulties in the use of FOSS as well as cultural difficulties related to it.","PeriodicalId":265555,"journal":{"name":"2012 IEEE Global Humanitarian Technology Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130255374","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}
