A Study of Appropriate Model of Unit Cost for Electricity Generation in Thailand
A Study of Appropriate Model of Unit Cost for Electricity Generation in Thailand

Today Thailand has been facing the energy problems due to the limited sources of natural energy. Meanwhile the power consumption has been growing constantly and the tendency of consumption increases each year. Therefore to solve these energy problems especially in electricity-generating power which have been demanded throughout the country the National Economic and Social Advisory Council had a resolution to submit the Cabinet the comments on nuclear-electricity generation and proposed the government for approval on August 24 2003. The government assigned the National Energy Commission’s policy to set out the electricity production plan by nuclear power plant requiring that the power house during 2020-2021 will be established. The Electricity Generation Authority of Thailand (EGAT) has executed “the Power Development Plan 2007” established the many sets of committees to accommodate the plan and carried out surveying for dominant information for examples parameters and variables issues of resulting effect and economic expansion so that these would be summarized and submitted to the government under the production plan procedure set out by EGAT. According to the production plan for future energy reserves the new power houses have been established. To accommodate the economic expansion some potential factors needed to be taken into consideration included fuel supplied and low cost. Previous researches demonstrated that nuclear power plant was lowest on cost. In present study the appropriate model of unit cost for electricity generation in Thailand was examined. The equation was described below;....

The Design of a Forecasting Support Models on Demand of Durian for Domestic Markets and Export Markets by Time Series and ANNs.
The Design of a Forecasting Support Models on Demand of Durian for Domestic Markets and Export Markets by Time Series and ANNs.

The objective of this research is to design forecasting support models on demand of durian for domestic markets and export markets for durian gardeners durian entrepreneurs of domestic markets and export markets and the Office of Agricultural Economics to plan durian demand conforming with domestic markets and export markets because of Production and marketing main problems (The Agricultural Information Center The office of Agricultural Economics: 2008) such as over - much durian production during production capital increased farmers durian sold price tended to be lower and lower inefficient domestic market management and more export but cheaper price therefore after that to design forecasting for the purpose in order that durian would not be over demand which is containing factors of the demand of durian fresh durian frozen durian paste and durian chips for domestic markets and export markets exported to Asia America Australia and Africa. The research involves historical collection data in the period of 2002 to 2008. The basic of forecast models are the designed and improved models using an intelligent knowledge-based approach beginning Moving average Deseasonalized Exponential smoothing Double exponential smoothing and Artificial neural network (ANNs) program within the model of new value Creation and comparative accuracy models. The evaluation result of forecasting durian demand showed that lowest MAPE of Deseasonlized models at 3 month was durian fresh durian frozen and durian paste but durian chips showed that lowest MAPE of ANNs at 4 input 10 hidden layers and 1 output was high accurate forecasting and optimal models. The analysis recommendations and error forecast of durian demand are also presented.

THE EFFECTS OF STUDY COOPERATIVE LEARNING MODEL THROUGH THE TEACHING OF FOUNDATION OF THAI CIVILIZATION SUBJECT: CERTIFICATED STUDENTS RAJAMANGALA INSTITUTE OF TECHONOLOGY ; POH-CHANG CAMPUS
THE EFFECTS OF STUDY COOPERATIVE LEARNING MODEL THROUGH THE TEACHING OF FOUNDATION OF THAI CIVILIZATION SUBJECT: CERTIFICATED STUDENTS RAJAMANGALA INSTITUTE OF TECHONOLOGY ; POH-CHANG CAMPUS

The objective of this research was to compare the study achievement on Thai Government and Politics of Higher Technical Certificate students of Rajamangala Institute of Technology Poh Chang Art Campus based on the teaching techniques. The total of 49 Poh Chang art students of the 2nd Semester 2002 academic year were simple random sampled and then randomly divided into 2 grcJps; 20 students for the experimental group and the rest for controlled one. The learning-centered teaching technique was used for the experimental group whereas the standard teaching technique was for the other. This research was nonrandomized control group pretest-posttest design. The research tool were the measurement for study achievement teaching plan of StudentTeams-Achievement division: STAD) and the group observation form for collecting the qualitative and quantitative data. Statistics applied for quantitative data analysis was ANCOVA (One-Way Analysis of Covariance) with the pretest score as the covariate. Interpretation was used for qualitative data analysis. The findings revealed that 1.There was a significant difference between the study achievement of the students at the level of 0.05 based on teaching techniques. 2.The experimental group had a better team working performance.

Construction of Ear Model with Papier Mache to be Teaching Media for Medical Students, Faculty of Medicine, Thammasat University
Construction of Ear Model with Papier Mache to be Teaching Media for Medical Students, Faculty of Medicine, Thammasat University

The objective of this research was the comparison of the efficiency between Papier Mache model of components of human ears and standard medical model. The method was composed of the quality determination questionnaire of the established Papier Mache model by anatomy medical experts. The efficiency test of the Papier Mache model was performed by a group of 30 third years’ medical students. The statistics used in data analysis were mean standard deviation and T-test (T-test Independent). This research of Papier Mache model meets the quality of the standard model from foreign countries and can be used as the model for the instruction education.

Analysis of Electric field and Modeling Design of High Voltage Cable terminators for PD Testing Using SF6 Insulator
Analysis of Electric field and Modeling Design of High Voltage Cable terminators for PD Testing Using SF6 Insulator

This paper presents the analysis of electric field by using FEMLAB simulation tool to find the optimal electric field and component designs. Design of Cable terminator is tested by finding PD Value with IEC standard. This paper also proposes the electric stress when we design the cable terminator includes SF6 insulator. The modeling design is very useful for High Voltage engineers to find the optimal solution of Cable terminator design.
