TITe pape7- presents the effectiveness of voltage stability indices for dynamic povver system modelling study in providing information about the proximity of voltage IN] collapse in power system. Four simple stability indices as Voltage Instability Predictor (VIP), Inpedance Stability Index (ISI), Line Index (L index) and Voltage Collapse Prediction hadex (V(-PI) are conapared using WS(-C9 bus testsystem. The Em comparison show the ISI and VCPI are much More reliable indicator, give the fast Ind indication and fast time computation than L index for voltage collapse in dynamics voltage collapse prediction.

A STATIC AND DYNAMIC TECHNIQUE CONTINGENCY RANKING ANALYSIS IN VOLTAGE STABILITY ASSESSMENT

The objective of the research is to compare between technique for determine the weak bus of the power system using static and dynamic contingency ranking analysis. Identification of the weak bus is very important for providing a proper control system to prevent for voltage collapse. Test system of this research is using the New England (IEEE 39 bus) power system. A severity ranking of the system is carried out on the study system to specify weak buses, in term of voltage instability. A contingency as a load increment is employed to examine the network buses condition and stability margin in the system. Three methods techniques as eigenvalue analysis of jacobian matrix is used as a static methods and a voltage collapse prediction index, and power transfer stability index as a dynamic methods are investigated. The result showed that the static analysis is giving more optimistic in evaluating loadability limit than dynamic. For the contingency ranking both static and dynamic give same trend in every bus. But for final decisions involving several consideration both planning and operation should be confirm by more accurate time domain simulation (dynamic) in which different characteristics of load, multiple controller, protection relays and coordinated them taken into account Key words: contingency analysis, static and dynamic analysis, voltage stabilit

Real-time remote control car racing system (PC Version)

The explosive growth of computer technology of today has broadened the minds of computer programmers and electronic engineers. Today, people from both industries are joining forces to create state of the art technology games at the international market. Therefore, we as future technopreneurs need to take this opportunity to learn about both industries and integrate them to make a useful product. In addition, this study is a new game concept which has combined with remote control hobby to create a new car racing game in the future. The idea is to use a real situation in gaming where by combining a few hardware devices (The Revolutionizer) and a software system (Speed Demon ver1.0 Beta) to make it run. The software design is being conducted using Unified Modeling Language (UML) 2.0 and being coded into Visual C++ programming language. The implementation stage is by using two types of R/C car (electric and gas) and the project has been successfully developed into a prototype product. The project is focused more on the R/C electric version. Overall, the project is now completed and ready to be market around the world. This is because the prototype which has been developed in this project has a high market value. Because of this, a business plan which contains all the information that a business plan needs to have for example, description of the product, industry analysis, marketing strategies, and the competitors. As a conclusion, this thesis is considered a unique of its kind in the information technology industry and the pioneer of turning research into money makin

Urban tourism concept in developing countries: qualitative study to the case of Melaka City, Malaysia

Most of the literature on the urban tourism phenomenon is based on the experience of cities in developed countries (e.g. United Kingdom, Western Europe and Northern America), while the study of urban tourism in developing countries has received little academic attention. This gap requires more exploration due to the unique characteristics and development of cities in developing countries. Melaka City demonstrates the increasing profile of tourism as a key urban function and portrays the strong interest of government in using tourism as a development tool. In this context, a case study methodology has been employed and a qualitative method was chosen in which interviews were conducted for the research. Thus, this paper attempts to provide a better understanding of the phenomenon and the complexity of urban tourism based on qualitative approach. The key information sources are based on the perspectives or views of those responsible for tourism planning in the city

Development of a user-adaptable human fall detection based on fall risk levels using depth sensor

Unintentional falls are a major public health concern for many communities, especially with aging populations. There are various approaches used to classify human activities for fall detection. Related studies have employed wearable, non-invasive sensors, video cameras and depth sensor-based approaches to develop such monitoring systems. The proposed approach in this study uses a depth sensor and employs a unique procedure which identifies the fall risk levels to adapt the algorithm for different people with their physical strength to withstand falls. The inclusion of the fall risk level identification, further enhanced and improved the accuracy of the fall detection. The experimental results showed promising performance in adapting the algorithm for people with different fall risk levels for fall detection
