An Evaluation Project of Using Degree Curriculums for Rajamangala University of technology Phra Nakorn, B.E. 2549-2550
The objectives of this lnstitutional research were an evaluation of using curriculums by studying and comparing opinion levels of students teachers and administrators inclusion in students’ satisfaction for educational process of Rajamangala University of Technology Phra Nakhon. The 1415 samples of this study were 1259 students’ 134 teacher and 22 administrators from six faculties which are as follows faculty of lndustrial Textiles and Fashion Design’ faculty of Science and Technology faculty of Engineering faculty of lndustrial Education faculty of Home Economics Technology and faculty of Mass Communication Technology. The data were collected by questionnaires and grouping by the samples. The results of this study were analyzed by percentage average value and Likert scale.
The Satisfaction of the Inspected towards The Internal Audit of Rajamangala University Of Technology Phra Nakhon
The purposes of this research were to study the satisfaction of the inspected towards the internal audit and to compare the inspected satisfaction in each aspect according to sex age job position and experience. The sample participated in this research consisted of 200 of unit executives faculty secretaries division heads and operating officials who dealt with the process of the internal audit. The tool used to collect data was a questionnaire; the statistics used to analyze the data were percentage Arithmetic mean standard deviation t-test one-way ANOVA and Fisher’s Least Significant Difference (LSD) was used after significant difference was found between groups.
Effect of Powder Sizes on Heat Transfer Characteristics of Miniature Sintered – Wick Heat Pipe
The objective of this study is to experimentally and numerically determine the effect of powder sizes on the void fraction which subsequently affects the heat transfer characteristics of miniature sintered–wick heat pipe usually applied in the notebook computer. The powder size of the wick is a profound influence on the heat transfer performance as well as the economic aspect of the heat pipe. By using computer program to simulate the void fraction of the sintered wick made of two sizes of metal powder and accordingly the mixture fraction of such metal powder the optimum throughput heat transfer of the miniature heat pipe can be predicted. The inputs of the simulation program are size specification the thickness of copper powder and powder fraction. The heat transfer characteristics of the heat pipe will be determined by firstly obtaining the void fraction of such sintered wick. Then the heat transfer rate will be calculated from the void fraction. The optimum void fraction can be solved as the point at which the void fraction and heat rate are appropriate on the basis of economic consideration. In order to validate such calculation the experiments have been conducted with several kinds of metal powders. The wick employs the copper powder with range of diameter of 150 - 212 and 250 - 297 micron respectively by wick molding with sintering process. The miniature heat pipe with outside diameter of 6 mm and the total lengths of 200 mm was used. The wick thickness was fixed of 0.46 mm. Water was used as a working fluid. From the result the heat transfer performance at normal state of the heat pipe with powder fraction of 1 : 3 has found to be as high as 25 W which is quite closed to the predicted one.
Design of an Algorithm for Tracking Symmetrical Component Based on Adaptive Algorithm
Symmetrical components of current and voltage are great importance in many applications in power systems such as power quality and power system protection. This paper presents the new adaptive linear combiner (ADALINE) structure for symmetrical components traction and estimation. This structure is deal with multi-output systems for parameter traction/estimation rather than the existing ADALINE which deals only with single output system. The new topology it is called MO-ADALINE is also presented. Finally the paper presents a new processing unit which can estimate symmetrical components from the measured current signals. The advantage of this proposed unit is simple to implement. Simulation results are given to validate the proposed algorithms.
An Application of GA Algorithm on Vehicle Routing Problem in a Case Study of a Bakery Company in Thailand
This research considers the vehicle routing problem in a specific bakery making company where is located in Bangkok. This company has to produce and deliver the bakeries to its customers everyday. Until now this mentioned company generates the delivery’s route by using the experience taken from the company’s truck driver. The company has to daily use the route with unnecessary long distances. According to the given statement this research aims to develop algorithm to generate the delivery route for this company by using the Genetic Algorithm in order to minimize the transportation distances.
