This thesis presents the combined loss reduction approach to apply in distribution system. The thesis objective reduces the loss in the distribution system when all voltage magnitude levels at connection points must under the limits. Therefore the Simulated Annealing Technical selects as searching tool to find the suitable location of DG and Capacitor. The propose technique applies to the distribution system 69 buses model. The results shown that this technique can reduce in power losses from properly organize the location of DG and Capacitor. Moreover it can also balance and increase the voltage levels. The propose Simulated Annealing Technical is used to determine and organize the sectionalizing and tie switches in the feeder which installs DG and Capacitor by considering the power losses and the number of time to change the status of disconnecting switches.

Most of Metropolitan Electricity Authority (MEA) electric power system is using overhead line. It is 94% in the system including subtransmission distribution and low voltage system. All of them were installed on concrete pole. At present many public facilities have been built such as Sky-Train. It causes more constrains for construction with concrete pole due to lack of right of way. MEA needs to using electrical monopole plays an important role. It’s easier than concrete pole for construction and it requires less construction area than concrete pole. The thesis evaluation of lightning performance in subtransmission line 69 kV study on MEA. Case lightning strike on overhead ground wire (OHGW) at pole top of electrical monopole with suspension insulator Focusing on three factors is pole top voltage critical current and back flashover rate (BFOR). ATP-EMTP software is used for simulation. The results show that BFOR is reduced by 79% on electrical monopole structure with suspension insulator compared with existing concrete pole. BFOR is also reduced by 33.17% on concrete pole with external ground wire. The results could be served as a guideline in subtransmission line design and improvement in MEA power system.

This thesis emphasizes the improvement approaches of quality on digital data to be more sharpness by two- dimensional technique. Today the availability from the improvement of Digital Image Processing is used widely in various occupations such as medical field with reading the results from CT scanning military field with the improvement of aerial map for country prevention agricultural field with leaf analysis of its disease and the educational field with the image processing and robot vision to increase its effective learning and remembering development. It can be seen that the image development through its sharpness is really crucial therefore this thesis used the Gray Scale for transforming by two-dimensional wavelet and LL Band got from this wavelet transform to be improved by histogram technique. The histogram was divided into 4 parts based on its cumulative density at 0.25 0.5 0.75 and 1 then smoothed the data by separation after that brought the results to invert wavelet which gives the new image through improved LL band. The research result revealed that the mean of the Absolute Mean Brightness Error (AMBE) was decreased while enable the image sharpness to suitably increase 80%.

The objectives of this research were to study the personal and environment and investment experiences factors influencing decision making to invest in the provident funds of The Office of the Rubber Replanting Aid Fund’s Staffs. The sample consisted of 341 persons from Rubber Replanting Aid Fund’s staffs at Bangkok office (central region). The research instrument was a questionnaire and using the descriptive statistic such as mean percentage standard deviation to analyze the data and Exploratory Factor Analysis : EFA and Binary Logistic Regression Analysis to test the hypothesis. The results of the study found that sex age the knowledge and investment experiences the risks of investment the economy the politics differences influencing the decision making to invest in the provident funds of The Office of the Rubber Replanting Aid Fund’s Staffs at statistically 0.05 significant level.

The purpose is to study the level of knowledge and understanding about AEC reviews and availability towards the ASEAN Economic Community (AEC) of the personnel budget. To study the influence of external factors include government policies. Media and public relations to a better understanding about ASEAN. The entry into the European Economic Community (AEC) of the personnel budget. To study the influence of external factors include government policies. Media and public relations to comment on the AEC. The entry into the European Economic Community (AEC) of the personnel budget. And to study the influence of external factors include government policies. Media and public relations to the availability on the AEC. The entry into the European Economic Community (AEC) of the personnel budget. The sample used in this study include civil servants / employees. And government employees / staff help practitioners. The operational budget The Prime Minister today (2558) based on statistical data personnel of the Bureau of the Budget of 1249 to determine the sample size formula Yamane have 303 people using sampling stratified into two stratified consisting stratified to one group. for example government officials / employees offices around Stratified sample of 249 people and the second employee / employees to perform. The sample included a total of 54 303 people as respondents. The data collected during the month of April 2559 the processing and analysis of data by a computer program. Using statistical analysis including the frequency of the Mean ( X ) the standard deviation (SD) and inferential statistics (Inferential Statistics) measurement relationship (Peason Correation coefficience) analysis regression slope. Logistics (logistic regression Analysis) and multiple regression analysis forecasting correlation (multiple regression Analysis). Analysis of the study data The external factors include government policies. Media and Public Relations Influence their knowledge opinions and availability of personnel Budget Office found that the analysis of the personnel on the perceived external factors include government policy towards the ASEAN Economic Community (AEC) of the personnel budget. the overall results showed that the levels are moderate. The recognition of the strategic plan for the promotion. And support for the ASEAN Economic Community (AEC) is a clear level is moderate. The Media Relations found that overall there is a perception in the grade level. The majority of staff are aware of the ASEAN Economic Community (AEC) by the television media is moderate. For a better understanding of personnel Bureau of the budget Towards the ASEAN Economic Community (AEC) personnel found to have insight into the understanding of the ASEAN Economic Community (AEC) snapshots are moderate. Data analysis showed that the assumptions on external factors include government policies. Media and Public Relations Influencing Knowledge The understanding of the ASEAN Economic Community (AEC) the significant level of 0.01 and 0.05 both positive and negative is very low. In doing research next time. There should be more education on other external factors. The influence of the ASEAN Economic Community. And there should be a study of the impact of the ASEAN Economic Community. With solutions to problems in the long run.
