This paper is a presentation of the Load-Frequency Control (LFC) of Interconnected Power System by using Fuzzy Logic and Artificial Neural Network (ANN) Controller. The both of controller have been widely applied for handling the system control of Industries and Engineering. Since the Load-Frequency behaviors of power system of uncontrolled and PI- Controller or Fuzzy Logic Controller (FLC) wanted to the stability at first of energize and load in a short time. The control system and controller then be significant for to go forward reform stability of interconnected energize power system a short time. In this research we have the Load-Frequency Controller of Interconnected Power System by using Artificial Neural Network Controller the improved can compared with conventional Fuzzy Logic Controller at power total 47.55 MW and load changing of power plan No.3 is 0.02 p.u. (1.75 MW)

The purposes of this research was to create the metacognitive learning activities for measuring the problem solving performance of 30 students who studies the introductory physics. The researching instruments composed of 6 parts: was included three kinetic lesson plans forms for recording students’ behavior forms for metacognitive measurement in solving physics questions forms for measuring the problem solving skills at students in answering questions and form for measuring the students’ performance in answering physics questions. The results showed that the instruction was conducted in 5 steps first planning for problem solving second identifying third executing fourth monitoring and the last evaluating problem solving that 23 students (76.67%) of students passed the physics problem solving ability test criterion of 60 % of the full marks which showed that the students had to develop physics problem solving ability.

Indium tin oxide thin films were deposited by DC magnetron sputtering from In2O3 and SnO2 as a ceramic target with 10 wt% of SnO2. The films were sputtered under pressure of 2?10-3 torr power density of 1.23 W/cm2 and substrate temperature of 200 oC. The main goal is to improve the optical properties of ITO thin films by using a mixture of oxygen and argon gasses with O2/Ar ratios varies from 0.0 to 0.5. The best average values of optical properties in the visible light region were found at the O2/Ar ratio of 0.2. The highest transmittance was 90.68% and the lowest reflectance was 9.42%. The result showed reflectance decreased by 5.52% compared to the films sputtered with only Ar.

This study aimed to 1) the evaluation of the design of Local History WebQuest of Mathayomsuksa 1 students based on constructivism through online social network revealed a high level of quality (= 4.62 S.D.=0.35) 2) the participants who studied Local History by using WebQuest with constructivism through online social network for Mathayonsuksa 1 students showed a better learning progress for no less than 20% 3) the participants’ satisfaction toward studying Local History by using WebQuest of Mathayomsuksa 1 students with the model that has been developed reached a maximum ( = 4.57 S.D. = 0.69).

The objective of this survey research were to study information retrieval on internet and and problems of the Faculty of Liberal Arts’ Students Rajamangala University of Technology Phra Nakhon. The stratified random sampling was 270 first semester undergraduate students of the Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon that were studying in academic year 2012. The research tool was questionnaire about information retrieval on internet of the Faculty of Liberal Arts’Students Rajamangala University of Technology Phra Nakhon. Statistical research were percentage median and standard deviation. The results showed that: 1. Each week most students retrieved information on internet more than 6 times per week and took average 1-2 hours each time. Aims of information retrieval were entertainment and recreation. Field of Tourism was the most retrieval i.e. tourist attraction recreational area hotels festival season and travel. The most information need format was text and pictures. Most students knew information sources on internet from search engines i.e. Google MSN Search etc. The first ranking of search engines was Google second were Bing and Sanook. 2. For information search methods most students printed required terms into search box by using keywords. Besides most students never used an advanced search. The most techniques of information retrieval was required results limit by specifying URL or websites. The students had the most selective method of information lists acquired from information retrieved results of search engine by viewing from information title that used for search engine. Whenever students did not seek required information they would retrieved continuously until they were successful by changing new search terms. 3. The most problems of students’ information retrieval were not to meet the required information and not to know search methods and search terms selection.
