Weather predictions by an atmospheric model are determined by the uncertainties in the initial condition and the imperfection of the model. It is difficult to provide accurate weather prediction. The efficiency of weather predictions model is obtained from the analyses of Lyapunov exponent. In addition the predictability measurements is applied from Lyapunov exponent are finite size Lyapunov exponent finite time Lyapunov exponent local Lyapunov exponent together with a new method called supremum Lyapunov exponent are used to measure predictability of the northeast monsoon (winter monsoon) by the Educational Global Climate Model (EdGCM) and to test sensitivity of the model to small initial perturbations. The EdGCM sensitive to initial perturbations it is suitable for predictability of the northeast monsoon. The EdGCM is run for 142-year predictions from the year 1958 to 2100. However only the outputs of geopotential height at 500hPa of December from 2012 to 2100 are used for predictability measurement. The results show that the EdGCM predictability for the northeast monsoon forecast is about 120 years. So the EdGCM can be predictability of the long range forecast.

Objectives of this research were 1) to study the environment of coopertive education program of the Faculty of Science and Technology Rajamangala University of Technology Phra Nakorn and 2) to study the achievement of this cooperative education program towards the development of graduates competency in the first semester of academic year 2013. Three sampling groups were from educational institutes enterprises and students. The number was 240 in total. Tools used in the research was a questionnaire opened and closed form number 4 sets were 1) questionnaire for coordinator or cooperative education officer advisor and lecturers 2) questionnaire for the executives coordinators or heads of human resources 3) questionnaire for employees consultant 4) questionnaire for cooperative education students. Performance analysis of cooperative education in the part of educational standard and the operation of science and technology using the content analysis method to comparing their content to the standard of Thai Association for Cooperative Education. To study satisfaction by using application program for statistical analysis such as frequency percentage mean standard deviation of mean values and descriptive discussion. The overall findings form this study showed that every relevant had high satisfaction with the management of the Cooperative Education Program of the Faculty of Science and Technology Rajamangala University of Technology Phra Nakorn.

The main objective of the study is to design blades for chopping heart rice straw. This study is composed of three main testing parameters. The first parameter used is speeds at which the knife blades that will chop the straw. They will have 2 speeds one at 540 and the other at 720 rpm. The second parameter is the types of blades that will be used eclipse blades and smooth blades. The last parameter is the cutting edges. The eclipse and smooth types of the blades will have 4 5 and 6 cutting edges. For this test we use stubble sorted 50 heart rice straws. Placing the straw on the prepared steel and test with all three testing parameters repeating each testing parameter thrice and record the results. Based on the testing and evaluation the 6 edge eclipse blades with a speed of 720 rpm. Yielded the highes results for chopping heart rice straw at 66 percent. For the 6 edged smooth blades with a speed of 720 rpm the yield results for chopping heart rice straw was at 35.76%

The purposes of this research were to (1) study the needs of teachers and students in Secondary Education Service Area Office 11 in English instruction using mobile electronic devices (m-Learning) and (2) to develop the model of English language instruction using mobile electronic devices (m-Learning) for Upper Secondary Students in Secondary Educational Service Area Office 11. The samples were 222 teachers and 394 students taken from Secondary Educational Service Area Office 11 using a Taro Yamane’s formula with the significant level of .05. The research procedure was divided into two phases. Phase one was the study of the needs of teachers and students in teaching and learning using mobile electronic devices two sets of questionnaires; one set for teachers and one set for students were used to collect data. A model of English instruction using mobile electronic devices was created in this phase. Phase two was the verification of the developed model by the experts. A verification form was used to collect data. Data were analyzed through mean and standard deviation. The research findings were as follows:

This applied research want to study the factors affecting the student‘ learning achievement instudying Data Structure and Algorithm. The samples were selected by stratified random sampling 93 students from 121 students who studied in semester 2/2009 by using questionnaire. The statistics used were descriptive statisticst-testOne way ANOVAPearson correlation and multiple regression at the significance level of 0.05. The findings revealed that the mean of grade point average was 2.69 their average midterm scores were 22.47 out of 35. The successful were grade point averagefair expectation of knowledgeand future application.The factors affecting student’s achievementwere basic knowledge of programmingmidterm scores studied resource and facilities. In addition the 2 year programme’ average midterm scores were higher than the 4 year programme ranging from 1.11 to 5.34 at the significance level of 0.05. The forecasting equation for learning achievement is
