The objectives of this research were to study the context of an information system for University’s Administrators of Ubon Ratchathani Rajabhat University to develop an integrated information system for University’s Administrators and to evaluate the developed system. The sample of the study included 24 administrator members and 7 officials at the Office of Ubon Ratchathani Rajabhat University. The research instruments were sets of interviews and questionnaires. Data were analyzed by content analysis mean and standard deviation. The study revealed that the information technology has been used in the department of Ubon Ratchathani Rajabhat University but the development is independent are there is a problem in report retrieval for university administrators. This study has developed an integrated system of information for university administrators by creating a data warehouse and establishing a connection between the data warehouse for each database. Data are stored in the data warehouse through data filtering of each daily segment in order to create a report for information which is accurate and running on network. The research results revealed that integrated information system for university administrators allows users to run a report according to the desired information quickly and easily. The evaluation of satisfaction and acception is at a high level a value of average is 4.40 and standard division is 0.55.

This paper presents the development of Automatic Malfunction Warning System (AMWS). The objective is to improve the performance of 5-kWp Grid-connected PV system with real time PC based monitoring system installed at Rajamangala University of Technology Suvarnabhumi Nonthaburi Thailand. The system is able to measure electrical parameters and air condition with real-time display. The AMWS comprises of hardware and software. The software was developed by LabVIEW. The AMWSs function is to monitor important equipment in the PV energy system. If there is a malfunction or any detected faults the AMWS would directly warn the operator of the PV energy system instantly. Results showed that the AMWS can complete programmed operation according to specified condition. The AMWS can send the right details and the cause of malfunction by SMS and E-mail every time the system did not work properly. The benefit of this system is that the operator can get the system to run properly and fix problems in a short period of time

Now a day the mostly air condition are use vapor compression refrigeration system in which R-22 refrigerant is used as a working substance. From the results of study it found that the quantity of water vapor or moisture in the air is condensed with in the fan coil unit while through out the evaporator. The fluid after condense is called condensed water. By this process the quantity of condensed water is increases when the air condition is used in the long time. To increase the utility the condensed water is recovered for the heart reduction in the finned-tube condenser. The experiment is consist of two conditions by using the air and condensed water to heart reduction. But in case of condensed watcr the pressure openation is controlled at 280 and 260 Psig respectively. The results of efficicncy ratio (EER) is 39675 Btu/hr 3.01 and 10.3 Btu/hr Watt respectively with the air is used At the pressure operation 280 Psig refrigeration effect (C.O.P) and (EER) is 44212 Btu/hr 3.38 and 11.5 Btu/hr. Watt respectivecly and 49856 Btu/hr 3.99 and 13.6 Btu/hr Watt at pressure operation 260 Psig. Furthermore the capacity of condenser is increases to 11.43% and 25.6% and also the refrigerant efficient is increases to 12.43 % and 32.43% at the pressure operation 280 and 260 Psig. Thus the pararneter of energy efficiency ratio depends on the capacity of condenser working substance temperature (pressure operation) and air surrounding tcmperature.

To store electrical power from solar cells are generally used battery as storage. Recent development in capacitor technology achieves with higher capacitancc smaller and low cost especially dcvelopment of a supcr capacitor (doublc laycrs). This research study used a super capacitor to store electrical power from solar cells. The results show that super and electrolyte capacitor can be used without battery with more power density and fast charge. But capacitor discharging must be controlled. The important disadvantage is super capacitor is used with low voltage and high rate of charge leakage. In case of electrolytic capacitor can use with higher voltage low rate of charge leakage but lower capacitance.

This research aimed to develop the prototype of information management systems for achievement evaluation and grade submission of Ubon Ratchathani Rajabhat University. The research process begins to study the need for the development of the prototype of information management system for achievement evaluation and grade submission. The research instruments were interview and questionnaires. This research found that lecturers needed to have a developed model for this system. It was found that the system including achievement evaluation grade submission and storing data were validity tested by grade information. Moreover the prototype model developed could be used as a model for the present education evaluation and grade submission at the university.
