This research’s objectives were to develop an energy saving rotary dryer for paddy using hot air recovery system and to evaluate the energy using. Rotary dryer divided rotating cylinder made of 304 stainless steel 2 mm of thickness 39 cm and 200 cm of diameter and length. The inverter was used to control speed of gear motor of 0.5 HP and rotating speeds of 1-3 rpm. The inside of cylinder composed screw and capture flights. The cyclone system was used to dust separating from the system. The moisture trap contained silica gel the outlet hot air was reduced moisture and recovered using. The fiber glass insulator was applied for reducing energy loss. The heating box composed 3 set of 1600 W heaters and blower motor power was 0.5 HP. In the experiment the drying temperature was varied of 50 60 70 and 80oC and cylinder speed was varied of 1 2 and 3rpm (15.66 10.66 and 5.66min of drying time). The initial moisture content of 10 kg paddy was 29.7?0.6 %wb. The result show that the optimum conditions drying temperature and cylinder speed were 70-80oC and 1 rpm (15.66 min) and final moisture content was 9.2-11.8 %wb. From the save energy testing found that the reducing of SEC was 0.4-0.6 MJ/kg water per drying cycle. There for this developed dryer can save energy using

The climate change is a natural phenomenon and effect on atmospheric which is the media of wireless communication. For the high performance in the telecommunication system this study therefore aimed to study the variables affecting to signal strength of wireless networks. The values of temperature humidity pressure and the signal strength of wireless networks 5 GHz were measured. The sample of this study was 148 access-points of TOT in Yasothon Province. For statistical analyses Pearsons correlation and regression were employed. The findings revealed that: 1) the average level of signal strength was 69.44 –dBm. The average levels of temperature humidity and pressure were 28.085 ?C 73.145% and 1004.246 hPa respectively 2) variables that had great influences on signal strength of wireless networks consisted of temperature humidity and pressure and 3) ambient variables of temperature humidity and pressure could predict the level of signal strength at 76.8%

The purpose of this research is to study the social responsibility of students in the faculty of technology management Rajamangala University of Technology Isan Susin campus. The samples used are Faculty of Management students of Rajamangala University of Technology Isan Surin campus in 2011 315 students. Tools used such as questionnaire. Results showed that Most of the samples are studying in Information Systems Management Accounting and the others. The social responsibility family responsibilities about their care and concern for all members of the family and Responsibility to the nation about the performance of their duties as good citizens by carrying an ID card at the highest level. Responsibility friend about respect and honor all sincere friends Responsibility for the school about praise honor and university is very proud Responsibility to the community about participating and helping to organize the annual event in the community such as Songkran Buddhist etc. at a high level. Samples with different gender age and disciplines. With social responsibility Responsibility for the school difference is statistically significant at the 0.05 level. The other four areas. Such as Family Responsibilities Responsibility friend Responsibility to the community and responsibility to the nation. No difference. Samples at different levels of education and grade levels. With social responsibility the difference is statistically significant at the .05 level. The 5 areas.

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

This research was to apply graphical method as the input data combined with using database for developing reinforced concrete slab analysis and design. Visual Basic language was used for creating the GUI (graphic user interface) and coding and database file was used for storing data. The position of beam column and slab can define by drawing on GUI and this program will automatic translate to be the distances for using as data in process of analysis and slab design. Results from analysis and design were compared with manual calculation that they are a litter bit error because of rounding error. Moreover they can be more economically and more conveniently than results from VisStructure 4
