The research of strategic accounting information systems of technology and targeted industry groups to Thailand 4.0 was aimed at studying 1) strategic accounting information systems of technology and targeted industry groups to Thailand 4.0 and 2) factors related to strategic accounting information systems of technology and targeted industry groups to Thailand 4.0. The questionnaires were constructed as a research tool for collecting data from 400 entrepreneurs in technology and targeted industry groups. The data was statistically analyzed by frequency distribution percentage mean standard deviation and multiple classification analysis: MCA. The research findings indicated that most entrepreneurs in the technology and targeted industry groups were in food agriculture and biotechnology. Their capital to run business at the present time was between baht 1000001-1500000. The average number of employees was 4.75. They had income of baht 500000 I -7500000 per year. Most of them employed companies or organizations to develop their own accounting information systems and their practicable period was 7.61 years. The capacity accounting information systems was totally at high level ( X =3.64). Also the usability of accounting information systems was totally at high level ( X =3.67) whose data collection was at X =4.00 data processing at X =3.66 data controlling at X =3.53 and information generation at X =3.51 respectively. The hypothesis testing results at statistical significance of 0.05 showed that the capacity of accounting information systems was the vital factor relating to data collection data processing data controlling and information generation and the annual income of entrepreneurs in strategic accounting information systems to Thailand 4.0 was related to data collection data processing and strategic accounting information systems to Thailand 4.0.

This project was created to sort bottles automatically. By specifying 3 types of bottles which are plastic bottles glass bottles and cans To help facilitate the separation of the bottles and then recycle the extracted bottles as needed. The organizer has studied the use of the Arduino program to control the operation of the sorting bottles according to the specified category. Studied the microcontroller system operation Control system And how to use the Arduino program The operating system is divided into 2 parts namely the metal detection sensor section And weight sensor and then send data to the sensor receiver Arduino And the sensor will detect the object all the time in the empty bottle compartment The results showed that the operation of the automatic bottle sorter system When throwing the bottle through the sensor compartment. The performance of the Arduino program that has been written to define the classification of the bottles. Have the percentage of work as specified by 90% and the error percentage of 10%

The purpose of this research was to develop an application for setting up price for goods in the community. The application helps the retailer calculate and determine the product price with the minimal risk. In order to assess the satisfaction of the application the samples used in this study were 30 community retailers and goods producers. The research found that the application was in good quality. The evaluation of satisfaction with the application was averagely 4.45 which was at a very high level. The application can be actually used in authentic circumstances.

Defrosting at evaporator panel is one of working cycles in freezer. Power consumption in defrosting does not meet the objective of using freezer therefore the approach to decrease power consumption in defrosting is one strategy for energy saving. Normally the cycle of defrosting in freezer is a constant time that specify by referring to the highest humidity period. With this control concept the problem of temperature exchange is not occurred from ice accumulation at evaporator panel but it makes the over necessity of defrosting process in the low humidity season and cause the unnecessary power usage in freezer. This thesis presents the control approach for defrosting by using the difference of the temperature at evaporator and the temperature at chilling area. By using this approach the defrosting process is operated depend on load and the fan is on or off relate to defrosting time. Test results demonstrate that about 12% of power can be saved by this control approach when compared to constant time control.

This study investigates three different types of power plant include a trilateral cycle (TLC) subcritical organic Rankine cycle (ORC) and supercritical ORC power plant driven by geothermal heat source with mass flow rate 1 kg/s and temperature of 100๐C 110๐C and 120๐C. with 27 substances were examined as the working fluid of the power plant. While the net power output of 4.78 kW and 7.74 kW is obtained from the subcritical ORC with RC318 as its working fluid when the heat source temperature are at 100๐C and 110๐C respectively. Meanwhile the net power output of 11.85 kW is obtained from the subcritical ORC with R227ea as its working fluid when the heat source temperature is at 120๐C. The net power output of 5.64 kW and 9.16 kW are obtained from the supercritical ORC with R218 as its working fluid when the heat source temperature are at 100๐C and 110๐C respectively. Meanwhile the net power output of 12.88 kW is obtained from the supercritical ORC with R143a as its working fluid when the heat source temperature is at 120๐C. Furthermore the net power output of 7.96 kW 12.27 kW and 17.38 kW are obtained from the TLC plant with heptane as its working fluid when the heat source temperature are at 100๐C 110๐C and 120๐C respectively.
