Comparing the Solution of the Stick-Slip Problem by Jacobi Iteration Method and Guass-Seidel Iteration Method
Comparing the Solution of the Stick-Slip Problem by Jacobi Iteration Method and Guass-Seidel Iteration Method

This object of research is to compare the computation solution of two numerical methods. The methods were Jacobi iteration method and Guass-Seidel iteration method for the stickslip problem at die of the extrusion process. The Navier-Stokes equation was analysed by finite element method of semi implicit Taylor-Galerkin/pressure-correction scheme to approximate velocity and pressure for Newtonian fluid in two dimentional cylindrical coordinate system. Solution accuracy was improved by the gradient recovery technique. The convergence analysis revealed that Guass-Seidel method approach to exact solution was better than Jacobi iteration method that is because Guass-Seidel iteration method had less solution than Jacobi iteration method.

Creating and Evaluating the Effectiveness of Computer Assisted Instruction Program for Reading Vernier caliper and Micrometer
Creating and Evaluating the Effectiveness of Computer Assisted Instruction Program for Reading Vernier caliper and Micrometer

The purposes of the research were to construct and to evaluate the efficiency of computer- assisted instruction program for reading vernier caliper and micrometer based on criteria and analyze the learning achievement of the student after using computer - assisted instruction. The samples were the first year undergraduate 17 subjects students at Rajamangala University of Technology Phra Nakhon in 2006 participated in this study. The experiment was conducted by using pretest post test design. The efficiency of the computer - assisted instruction was calculated and was the learning achievement of students after studying analyzed. The result revealed that the efficiency of the computer - assisted instruction was efficient in criteria and learning achievement significantly increased at .05 level.

Creating and Evaluating the Efficiency of Computer Assisted Instruction Program for Courses of Physical Fitness
Creating and Evaluating the Efficiency of Computer Assisted Instruction Program for Courses of Physical Fitness

The purposes of the research were to create and evaluate the efficiency of Computerassisted Instruction Program for courses of Physical Fitness based on criteria 90/90 and to analyze the learning achievement of the student after using computer - assisted instruction. The samples were 20 first-year diploma students at Rajamangala University of Technology Phra Nakhon North Bangkok Campus. The researcher did the experiment by using pretest and then implementing the computer assisted instruction program for courses of Physical Fitness. After that the students did the posttest then the researcher calculated the efficiency of the computer - assisted instruction and analyzed the learning achievement of students after studying.The result revealed that the efficiency of the computer - assisted Instruction was efficient in criteria 90/90 and learning achievement increased significantly at 0.05.

The design and development of young rice planting machine for use in the North Eastern part of Thailand
The design and development of young rice planting machine for use in the North Eastern part of Thailand

This research aims to investigate the efficiency and quality of young rice planting machine which is suitable for the North Eastern part of Thailand. The investigation applies the notions of planting young rice manually by farmers into the design of a battery-driven young rice planting machine. The researcher started with the study of transplanting methods of agriculturists in the North Eastern part and the design principles of young rice planting machine. Next the components were calculated and engineering design was drawn. Then the machine was tested in terms of its efficiency and quality. The data were analyzed in terms of means. The results show that the efficiency of the machine regarding planting performance is 90 % the appearance of the machine functions applications engineering and safety achieve the average point of 3.70 which is considered satisfactory.

Development of Fabric Products and Technology Transfer to Lopburi Communities
Development of Fabric Products and Technology Transfer to Lopburi Communities

The objectives of this project were to develop household items using cotton and silk fabrics weaved from local communities in Lopburi province and to transfer the developed technique to those communities in order to increase their incomes and also create the new career. There were 60 participants who were trained for two training courses. After training the participants’ satisfaction on the curriculums and training methods were evaluated by a mean of questionnaire. Then the average values were determined and used to represent the results. The results were concluded that the objectives of the curriculums as well as their structures were mostly suitable in every aspect. The satisfaction on activities during the training training equipment (materials and books) and place were rated in the “high level” while the satisfaction on the instructors was rated in the “highest level”.
