- PublicationComparative study and technical performance analysis of energy saving devices(2025-03-24)Sharmiga A/P RavintharThis is a research basis project focusing on energy or utility bill saving devices that is being marketed all around the world. This thesis consists of research on two energy saving devices which is the capacitor banks and energy saver card or in my research I am using the Power play card. My project will be a study on the capacitor banks and the Power play card on how it saves electricity theoretically and whether it is true. The main aim of my project is to determine whether these devices do really save electricity or utility bills and if it does how it saves and if it doesn't what is the use of these devices and how is it related to energy saving as claimed by sellers. If it does save energy my project will also determine which device performs better.
25 7 - PublicationThe effects of different barium doping concentration on the electrical and magnetotransport properties of magnetoresistive NBMO(2025-03-13)Mohd Sofwan Mohd SafienThe effects of different Barium doping concentration on the electrical, structural, microstructural and magnetotransport properties in colossal magnetoresistive Nd1. Ba,MnO3 at x= 0.20, 0.25, 0.30 and 0.35 has been studied. All four samples were prepared through co-precipitation method at sintering temperature of 1200°C. Through X-ray diffraction measurement, all the samples are found to have an orthorhombic structure, single phase and can be indexed into Imma space group. The highest peak for every sample occurred in <200> direction. As the value of barium doping concentration increase, the insulator metal transition temperature, Tim is decreased except for sample with x=0.30. Magnetoresistance (MR) measurement was carried out in the presence of magnetic field ranging from 0.1 T to 1 T at room temperature. The highest value (~58%) of MR is obtained at sample with x=0.25 at 1 T. All the electrical resistivity data exceed 0.98 value in both equation of p(T) = Po + P2T2 and P(T) = Po + P2.5T2.5 at temperature lower than Tim, which indicates that the grain boundary effects, electron-electron scattering and electron magnon scattering process is highly responsible for the resistivity behavior. At paramagnetic insulating regions where T> Tim, variable range hopping (VRH) and small polaron hopping (SPH) model fit exceptionally well in the equations which signifies that the polaron hopping is responsible for the conductivity.
8 15 - PublicationDesign and development of a low cost antilock braking system using pic microcontroller solenoid contorlling mechanism(2014)Mohamad Farhan Mohamad SabriSafety features are most important roles of modern vehicles. Antilock Braking System are considered as essential features that public citizen consider before buying a car. The cost of lives is precious However, the high price of ABS's components, which is the Electronic Control Unit, makes the maintenance of a fully functional ABS is a burden. To solve this problem, a solution which makes uses of the PIC microcontroller is being introduced. In this thesis, the potential of PIC microcontroller to control the switching of solenoid valves is tested.
25 73 - PublicationVoltage stability evaluation using indexes based on static and dynamic simulations(2024-12-04)Mohd Kairuldin Abd RahmanIn the time of rapid growth, there is an increase of demand due to build up many factory and heavy industry around the world. Due to this, utility companies are forced to operate their power system nearer to its maximum capabilities since system expansion may be a costly option. The utility companies operate power system at maximum capabilities cause the power system will be at risk to voltage collapse. Voltage collapse gave bad impact to the power system operation. The ultimate effect of voltage collapse would be total system collapse which would incur high losses to utility companies. This project evaluates voltage stability of selected system(s) based on static and dynamic analysis using PSSE software with various types of index. The indexes involved in analysis such as Fast Voltage Stability Index (FVSI), Line Stability Index (Lmn), Line Stability Factor (LQP) and Line Voltage Stability Index (Lvsi). The indexes used to identify of weakness at line and in power system. The analysis started with nine bus static and dynamic simulation and further with thirty bus static and dynamic simulation. Every simulation is divided to three cases analysis. Every cases have own purpose and it more referring to base case analysis. The detail analysis are presented in all cases static and dynamic simulation.
58 124 - PublicationAnalysis on power system behavior subjected to symmetrical and unsymmetrical fault using PSS/E software(2024-12-04)Hasrul Rafandi HaroonPower System, behaves differently during normal and abnormal conditions. It is for important to analyze the behaviour of power system at both conditions for planning and design purpose in order to make sure that the system remains in stable condition with its critical parameters within the acceptable limits. This project will focus on the analysis of power system behaviour during normal and abnormal conditions including symmetrical and unsymmetrical faults. To design a better system for the power utility, was conduck & a study must be made to find the behaviour of the system during the occurrence of to fault in order/determine the weakness and the condition of the system and then develop the new idea for improving the power system. For this analysis, PSS/E simulation will be used in modelling the system and simulating the system according to the various types of fault that may occur in the power system.
