Undergraduate educational management of Rajamangala University of Technology Phra Nakhon has mission point to science and technology vocational based on quality professional workers. Applied technologies on the engineering works have continuous and high progress. The researchers want to emphasis with human development for stepping up to professional works in The life long studying on working period of faculty of industry textile and fashion design Rajamangala University of Technology Phra Nakhorl. The research objectives are as follows: 1.To know they want to add more performance or to change from nature of the undergraduate field to others 2.To make the teaching discipllries for gain their standard lffiowledge higher 3.To study the life long studying on working period offacuity students and alumni. Domain of research and the participant groups 1.students who studying at Rajamangala University of Technology Phra Nakhon 2.Alumni want to change their graduated field to others or gain their performance. The research results found that the platforms are according to require on the life long studying in faculty of industry textile and fashion design have to stress on teaching for gain their performance with technology involvements such as production process coloring process textile printing graphic design and computer cutting forms according to short period not more than 6 months for studying. The discussions from participants point to continue to study for gain their performance first because economics rapidly changing and several firms want the best persons. They have a lot of best knowledge worker and high performance to work with them. The participants require 1-6 months for studying because the competitive workers in the specific working markets.

Creating and Evaluating the Effectiveness of Computer Assisted Instruction Program for Computer for Jewelry Design
Creating and Evaluating the Effectiveness of Computer Assisted Instruction Program for Computer for Jewelry Design

The purposes of the research were to create and efficiency validation of computer assisted for the Computer for Jewelry Design based standard 90/90 and analyse the leaning achievement ofthe student after by using computer assisted instruction. The subjects in the study were 17 first year diploma students enrolled in Rajamangala University of Technology Phra Nakhon. The Researcher using the experiment by let the students do until test before class And then study by using computer assisted Computer for Jewelry Design. After that let students do the unit test again at the class and calculate to fmd out the efficiency of the computer assisted instruction and analyse the leaning achievement of students after study . The research result revealed that the efficiency ofthe computer assisted Instruction was efficient in standard 90/90 Moreover after learning achievement At significant level of 0.05.

Design of an Algorithm for Tracking Symmetrical Component Based on Adaptive Algorithm
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.

Speed Control System Design in Bicycle Robot by Low Power Method
Speed Control System Design in Bicycle Robot by Low Power Method

This paper presents compare results performance between two conventional controllers for bicycle robot. The bicycle speed control system was a highly nonlinear model multivariable and absolutely unstable. It has used for testing various design control techniques for low power. The objectives of this paper had to developed speed control which derived the mechanic model and experiment. Controllers are Proportional-Integral-Derivatives (PID) and on-off dynamic control. The dynamic system which also includes not stable friction effects the linear zed system model is used as a basis for the design to apply to speed. Computer simulation and experiment have been done controller are capable to control output speed wheel control system successfully. The results show PID controller better then on-off dynamic controller.

Optimization of the Aluminum Riveting Process Using an Experimental Design Technique
Optimization of the Aluminum Riveting Process Using an Experimental Design Technique

The purpose of this research is to determine the optimal factors existing in the aluminum riveting process. First a 25 full-factorial design was used to screen five factors and two levels by selecting a lapping-joint method using only one rivet which exhibited significant riveting shear. The five riveting parameters used were press force 5000 and 8000 newtons a thickness of material of 2.5 and 4mm a size of hole of 4.7 and 5.2 mm over long rivets of 4.7 and 5.2 mm and press times of 5 and 15 seconds. There were three parameter levels: thickness of the metal (2.5 3.2 and 4.0 mm) size of the hole (2.5 3.2 and 4.0 mm) and size of the over-long rivet (4.5 5.6 and 6.7mm) then a Box-Behnken design was used in order to analyze the data and find the optimization point. The experiment found that a standard rivet has a shear strength resistance of 1113.30 newtons. The study methodology was to prepare the riveting specimens use by selecting a lapping joint per one rivet to test the mechanical quality and shear. The results of the experiment show that the optimal conditions (to a statistically significant degree) were to use a 5.2 mm hole a 2.8 mm level of thickness and a 6.3 mm over-long rivet. The optimal point for the shear test was 1417.55 newtons and an over-shear strength of 303 newtons could be increased by 27.32 percent.
