Presently the rail transit system plays a major role in the commercial world that they currently use diesel engine not only causing to a lot of fuel consumption but also generating numerously pollution. Therefore this project aims to study the break-even point of investment under comparison of brake specific fuel consumption and pollution of locomotive engines. By experimental works there are 3 types of locomotive engine: Pielstick M.T.U. and Caterpillar which are the difference of the combustion chamber and the fuel injection systems. The simulation load on the static tests (Dynamometer) was used following the regulation characteristic curve which is standard of State Railway of Thailand. As a result of testing the engine using common rail type of fuel injection system M.T.U. was the lowest brake specific fuel consumption at all of engine by the average of all engine speed 206 g/kW-h of brake specific fuel consumption. It is lower than Caterpillar (Semi common rail with direct injection) which is 314 g/kW-h equivalent 34.39 % while Pielstick engine a mechanism fuel injection system is 389 g/kW-h equivalent 47.04 % For pollution area there are Hydrocarbon (HC) Nitrogen Oxide (NOX) and black smut. The engine with direct injection system relieved the previous substance less than the pre-combustion engine. Moreover the compound of carbon monoxide (CO) was found that the pre-combustion engine (Pielstick) discharged carbon monoxide (CO) less than the direct injection engine (Caterpillar) whereas the common rail engine emancipated same substan cenear by with the pre-combustion engine (Pielstick). However the new technology of the engines is high maintenance costs. Therefore a number of applications have to be needed to make a quantitative value for the investment.

A distributed generation is a small-scale Installed in the customer density sources. The benefits of distributed energy resources is one example. To improve the reliability of power distribution system for the better. The increased reliability of power distribution system that is connected to the source of power distribution efficiency depends on the size of the supply and installation of power distribution are considered appropriate. To Evaluation the reliability in distribution system with the main purpose is to the minimization for customer interruption cost. The technique employed to minimization problem for customer interruption cost in solved by the developed tabu search algorithm together with reliability worth analysis that provide an indirect measure for cost implication associated with power failure. The developed methodology is tested with a distribution system of Roy Billinton Test System (RBTS) bus 2. Numerical results from the tests demonstrate that distributed generation can be used to promote economy and reliability of the distribution systems.

The objective of this research is to study the readiness and procedure of the personnel in coping with the entering Asean community from example group of 126 people which classified by sex ages position educational degree field of work salary and working life. This study uses questionnaire as a tool in collecting data that could be categorized in three aspects knowledge skills and attitudes. The questionnaire is five rating scales that analyze the result by frequency percent average the average of standard deviation and T-test independent by using one way ANOVA. The results were as follows : From one hundred percent of the personnel of faculty of Engineering Rajamangala university of technology phra nakhon which 58.25% classified by the educational field and 31.75% support line are ready to enter into Asean community which could be seen average in whole picture. After considering in three aspects it appeared that knowledge and skills of personnel are also average. However the attitude of personnel was considered in a high level. Hypothetic test result was found that there was no difference among the personnel with difference sex ages position educational degree field of work salary and working life in their readiness in entering Asean Community.

This study was aimed to investigate income and expenses which led to indebtedness of Royal Aide De Camp Department noncommissioned officers. The questionnaire was administered as the instrument for collecting data and the investigation was performed among the entire population using Survey Analytic Studies. The samples were 40 Royal Aide-De-Camp noncommissioned officers. The results of the study revealed that most officers had 100001 – 500000 in estimate and took on more public loan than pawnbroker’s loan. The public loans were taken from Cooperative saving banks while the pawnbroker’s loans were from relatives or friends. Their consumption behavior which caused indebtedness was expenses on buying household equipment such as washing machines fridges televisions etc. From primary analysis noncommissioned officers who were most in debt were Sergeant Major 3rd class(SM.3) Sergeant Major 2nd class (SM.2) and Sergeant Major 1st class (SM.1) who had worked for over ten years. They were married and had children but their spouses did not work with the total income of 5000 Baht.

The objective of this study was to investigate factors related to budgeting in 2014 fiscal year: a case study of OTEPC. The samples were chief executive officers heads of the departments and 80 officers who were responsible for the project. A questionnaire was administered as the research instrument to collect data which were analyzed by percentage and Pearsons correlation. The findings were as follows: (1) In terms of personal factors it was found that most of them were female who were above 51 years old. They had master degrees and were in charge of heading the team as well as being the team staff with lower than six years experiences in handling budgeting tasks and had 30001 – 40000 baht salaries. (2) The relationship between handling budgeting study of OTEPC projects processes activities and achievements were in high level especially when the chief executive officers work agreed with the governmental policies followed by their legal exercises in relation with their decision making and officials’ participation which connected to those decisions. The government policies and its law exercise demonstrated low relationship as well as the governmental law exercise and the officials’ participation respectively.
