Canonical Correlation Analysis Between some Factors and Motivation on Producing Academic Papers of Instructors in The Office of Rajamangala University of Techlnology Phra Nakhon
The purposes of this research were to study the canonical relationship between some factors and motivation on producing that relative contribute to academic papers and to study the canonical weights of some factory motivation on producing academic papers. The Sample were the 222 instructors in the office Rajamangala University of technology Phra Nakhon who work during the first semester of Academic year 2005. The stratified random sampling technique was used for selecting the sample. The instruments were the questionnaire considering the salary work load working experience Attitudes toward producing academic papers Self development Internal control Academic ability Motivation on advancement Motivation on recognition and Motivation on environment of producing academic papers. The findings were as follow: 1. The canonical correlation between Salary Work load Working experience Attitudes toward producing academic papers Self development Internal control Academic ability Motivation on advancement Motivation on recognition and Motivation on environment of producing academic papers were .510 .231 and .134 respectively. The first canonical function was Statistically Significant at .05 level. The second and third canonical function were Statistically nonsignificant. 2. The canonical weights for Attitudes toward producing academic papersself development and Internal Control relative contributed to Motivation on advancement Motivation on recognition and Motivation on environment of producing academic papers in the first canonical function.

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.
