This project report proposes a design and construction of model of protection equipment for three-phase transmission line by voltage relay for protect. By protection equipment can protect the transmission line from over voltage and under voltage on the transmission line The objective of design and construction model of protection equipment for three-phase transmission line. The objective for construction model of protection equipment for three-phase transmission line. For understand power system protection principles. And understand using to protection equipment for three-phase transmission line correct. From experimentation model of protection equipment could protect over voltage and under voltage on the transmission line

Nowadays an automotive industry steadily has been growing and playing a major role on economy development for many years. The crash box is one of the most important parts for safety but it was found that the crash boxes manufactured domestically are not met international standard requirements. This is due to process and material limitation. This process for automotive safety test requires high budget and there is unclear approach for specific test. Therefore a study of crash boxes referred to energy absorption project was conducted as an alternative choice of testing. Regarding to the problems as addressed above this project was aimed to design and test crash boxes which come in various structures; simple type corrugated type and honeycomb type of crash box. In addition it was also emphasized in studying energy absorption behavior and physical deformation of crash boxes after dynamic and static energy being applied. Numeric simulation and static test methodology of front collision were applied for these tests in reference to USA NCAP standard for automobile collision test. Testing all types of crash boxes indicated that the corrugated type was able to absorb energy at 2.8% and 5.9% higher than honeycomb type and rectangular type respectively. This is capable to pickup stress and strain continually and effecting to more energy absorb than another type. Additionally this corrugated structure is feasible and suitable for crash box design in automotive manufacturing.

This thesis presents the design and construction of an experiments of the power flow in the power systems. For the operating system of the power flow in the power systems. Comprise with the real power Reactive power Voltage in the power system. To guide the planning and operation of power systems. The results of the experiment to calculate the pressure at various points in the Power loss of system. As well as finding solutions to problems. Occurring in the system such as under voltage or short circuit in the system. This is the basic of stability analysis of power system operation and planning

This research explored the Marketing Mix (4P’s) factors affecting vocational education textbook buying decision of target customerss Wankaew Edutainment Co.Ltd. in Bangkok metropolitan area. The Population in this study are teachers and lecturers belong to vocational schools in Bangkok. The equation used to calculate the unknown sample population at 95% confidence level. The sampling and statistical sample of 400 active research. That have statistics used in this research is the Binary logistic regression. The results showed that with ten issues from three aspects that affect buying decisions. The level of statistical significance was 0.05 The 4P’s product clarified on two issues includes learning plans and test examination for course number 200 as a Microsoft Word file containing a CD and given to the print format four-color throughout. The 4P’s place focused on three issues as books sold through shops in the area close to the Lyceum sales by telesales and distributed E-Commerce system. The 4P’s promotion focused on five issues as counseling services academic and teaching buyer can author textbook buyer invite participants academic buyer have joined academic work and advertising through social media and website

The research aims to develop the innovation development of fashion bags design and the product design by using silk fabric Napho District Buriram. To introduce the technical innovation development of fashion bags design and development of the product design by using silk fabric Napho District Buriram and to develop Thai Community Product Standard (TCPS.) in Buriram Province. The instruments used in research were interview the comment assessment form and the designs assessment form. The sample consisted of 100 interested people. The statistics tools used in data analyzing were frequency percentage mean and standard deviation. The result of the research found that Ban Napho Community Enterprise Group in Buriram Province produced the silk fabric with complex patterns in various colours and styles. It was local knowledge that was unique and useful in conservation education as well as in development. Ban Napho Group have designed and produced textile products by using silk fabric such as Tailor fabric clothing bag scarf and other but they needed to be continually upgrade the designs in order to modernize. The result in this research regarding to fashion bag design revealed that most respondents from the 100 interested people were female employee aged 31 to 40 years having an average income 5001 to 10000 baht and below a Bachelors degree. For the design assessment the result showed that these interested people had positive attitude level in prototype fashion bag No.5 for pattern design application and the overall average at 84 85 and 86 percentages respectively. The transfer of technology evaluation the results showed that prototype fabric bag No.5 was positive attitude in high level for overall pattern design and decorating at 86 percentages and prototype fabric bag No.6 was at 82 percentages respectively. The research finalized the highest score of prototype fabric bags and 5 phototypes were selected without respectively such as phototype No.1 2 5 6 and 9. They were selected for making the sample in order to introduce the knowledge to the local community.
