The purpose of the research was first to study the need of information technology application in second to study the types of information technology services that is effectively corresponding to the need of users. The third is to study information technology application in cassroom teaching and the last forth is to apply all these strategies to Rajamangala University orf technology phra Nakhon. In the research the examined population was both academic staffs and students of Rajamangala Univessity of Technology Phra Nakhon. Their samping mumbers selected from all 9 faculties were total 1506 peoplecounted of 80.97 percentages. The research tool used was questionnaires in order to engaging the effectiveness and the need of basic factor of information technology. For the data analysis one=way analsis of variance (ANOVA) approach was chosen for the study. In this study the results showed that most staffs thought it had majior effectiveness of information technology mangement with a mean value off 3.475 whereas most students though it was medium effectiveness with a mean value 3.393. For the needs of information technology most staffs considered it a hight range of an average at 4.420 while the students believed its importance with an average of 3.686. Besides for this same need both staffs and students from various facultes had same major opinons that there was no difference at the statistic significant level of 0.05

Today wireless sensor networks are developed and comprised of a small fully autonomous processing communication and sensing devices. It has been restricted power supply low computing power. WSNs work in vast area unreachable or crucial area send and receive raw data from each sensor node. It has the ability to cooperatively collect data and retransmit in order to process or alert. This paper used ns-2 simulation propose a power efficient wireless sensor network ant colony system that can adapt it’s function to reduce average energy consumption per node and work in area for a longer time.

Aluminium was used in many industrial applications due to good properties such as ductile high corrosion resistant and high electrical conductivity. Since wear resistance of aluminium was very poor so that it was a limitation of using this material in several conditions. In this research aluminium was improved the wear resistance properties by using anodizing process and adding some titanium dioxide particles on the surface. The effect of anodizing process duration on the wear resistence property was studied. It was found that the process duration and amount of titanium dioxide play the important role on improvement of tribological properties of aluminium.

Aluminum is a lightweight material which are popularly used in various parts of the industry. However there are some limitations on the tribological properties such as abrasive wear and friction when it was compared to other metals. Tribological properties of aluminium was improved with anodizing process and silicon dioxide supplement. the effect of time on surface structure and friction coefficient were studied with with scanning electron microscope and sliding wear tester. It was found that friction coefficient of aluminium was decreased after improvement process was applied.

This paper presents a CMOS voltage reference design which is widely used in electronic circuits both analog and digital circuits. In the conventional a CMOS voltage reference circuit design composed of several MOS transistors and complicated circuits the output voltage cannot be adjusted to any levels. Therefore in this paper proposed the CMOS voltage reference circuit design technique based on a new current combination circuit which it was reduced number of MOS transistors and the proposed circuit is able to operate without complex startup circuit. The performance of the proposed circuit is confirmed through PSPICE simulation results the circuit can be operated with supply voltage varies from 2V to 4V the output voltage reference is about 231 2mV at wide temperature range of -80 to 120 it has very low temperature coefficient of about 37.65 ppm/ and a total power dissipation of 7.37 W
