In this paper we have analyzed the performance of combining security system (SSL Protocol) with current TCP/IP module by porting security shareware into the EDC (Electronic Data Capture) devices. Finally in order to understand the impact on the EDC’s performance we test the throughput of the EDC before and after applying security with various encryption algorithms.

Rajamangala University of Technology Phra Nakhon had signed an MOU with the Ministry of Science and Technology to set up a Clinic Technology in January 2003. The Clinic has operated since the fiscal year 2004 with subsidiary from the Ministry of Science and Technology. It has a main duty in transferring technology providing consulting and information services on technology research and development and distributing knowledge and insight in science and technology. In 2005 the Clinic received a budget of 3278100 baths in 9 projects that provided service for 4171 persons. In 2006 a budget of 1786500 baths was allocated for 6 projects that provided service for 2017 persons. In 2007 it received a budget of 2622000 baths in 12 projects that provided services for 2874 persons. The Clinic has achieved a success in reducing expense increasing income and enhancing life quality of communities. It obviously has an important role in integrating research work into technological transfer and economic development of communities.

Since its original inception under the name of Rajamangala Institute of Technology and now as the Rajamangala University of Technology Phra Nakhon RMUTP has a long history of initiating research projects in order to help develop and improve the overall well-being of the Thai population and the countryûs economy. The Banana Product Development Project was one such research project that was established to serve the community. Its objective was to solve the banana problem in the local Thai community; that is the problem of having more bananas as a result of low consumer demand. The project findings would therefore create new innovations to help the community and develop its economy. This research project was started in 1976 and from around 1997 has been transferring the research result to the communities. The project is still currently active and highly successful. It has won awards in both national and international competitions as a result of successful developments which include for example the establishment of a Thai Banana Club Banana Product Development as a result of extended research and technological improvements in order to help the community the economy and local industries

Now a day the mostly air condition are use the air for reducing the temperature at the condenser unit. Moreover many dusts are adhering in area of fin coil. From this reason the heart reduction efficiency is decreased and increasing the energy consumption. Thus the aim of this research is to design the finned-tube condenser unit cleaner machine for increasing the heart reduction efficiency. From the results of experiment it found that the finned-tube condenser cleaner machine is desirable when comparing with the performance before used. By the original performance the refrigeration effect coefficient of performance (C.O.P) and energy efficiency ratio (EER) is 34179 Btu/hr 2.62 and 8.9 Btu/hr.Watt. On the other hand the refrigeration effect (C.O.P) and (EER) is 39766 Btu/hr 3.12 and 10.7 Btu/hr.Watt respectively when the condenser unit cleaner machine is used. Based on this condition the value of the refrigeration effect and (EER) are increase to 16.35% and 19.19% respectively. Thus the heart reduction in condensing unit can be aided the performance and prolong the life time of air condition by depending on the cleaning of condensing unit.

This paper presents a testing of three insulators namely solid fluid and gas for choosing the best electric insulators. In order to generate the ozone gas the insulator must be selected in electrode set. Nowadays the insulators do not have the optimal test procedure for getting total efficiency. Therefore in this paper a design of ozone generator is proposed by using the fundamental of electric field stress. The ozone generator is a coaxial cylindrical electric type that has solid insulator in center of glass tube. This solid insulator will be dielectric among the high voltage electrodes. Ozone gas will generate in this air gap. This paper also focuses on the insulator testing of three insulators. It will find the efficiency of 3 insulators and compares them with the density and stress of ozone gas. The experimental results show the performance and ensure the optimal ozone generator design.
