This project is intended as a teaching medium air conditioning system and simulation of air conditioning system problems. Some of them have been modified to suit their teaching needs. Arduino microcontrollers are used to control the system. By starting the study of the air conditioning system thoroughly. The microcontroller is written to control the operation of devices like the air conditioning system when the system malfunction. It will be used to analyze the problems of air conditioning. The experimental set will display the voltage and current. The connection points of the air conditioning problem analysis. When the symptoms are bad. The analyst can solve the problem by connecting or pressing the button of the device. The results of the project. The test will measure the difference of the air conditioning unit. And read the amount of current and volume in the system. To diagnose abnormalities and choose a solution to the problem from the kit system that can be displayed to solve the problem that the analyst was correct or not with the LED status light. Based on the performance test a demonstration kit for the demonstration of efficiency of the air conditioning system was provided to 10 experienced air conditioning technicians. 80s of issues. The reliability of the demonstration set and the efficiency of the simulator case study of the electrical system in air conditioning systems is acceptable

Nowadays the measurement technologies are continually growth in advanced. These can be seen in the developed and developing countries that research and develop the products which support the consumer behavior and/or country economy ic growth. However some advanced products are very expensive such as pH meter. Therefore this thesis develops the pH meter which allows the acid-base test of the water and it can be supported the agriculture. The proposed pH meter is included the pH pen sensor temperature sensor water level sensor. The proposed meter can measure the acid-base of the water by sending SMS alert signal via GSM module to the mobile phone of the farmer. As can be seen this thesis can prevent and solve the effect of the high acid-base of the water that possibly flows into the agriculture farm via using SMS alert signal of the mobile phone of the farmer.

The purposes of the research were to 1) study the attributes of the graduates according to standards of learning outcome 2) study the 21st century skills of English for International Communication graduates desired by employers 3) compare the attributes of the graduates according to standards of learning outcome categorized by the individual factors and 4) compare the employers’ requirements to skills of English for International Communication graduates categorized by the individual factors. The population were 55 employers participating in the cooperative education project in the academic year 2017. The research tools were questionnaires and interviews which were analyzed by the SPSS program. The statistical data analysis was performed by frequency percentage mean standard deviation and Fdistribution and the interview data analysis was performed by frequency and content analysis. The results were found as follows. 1. As for the employers information33emoloyets were from private and service businesses (60%) and 14 employets were from government sectors (25.50%).As for the working statuses29 employers were the officers (53.70%) 20 employer were the supervisors (37.00%) and 5 employers weie mangers (9.30%) 2. The overall requirement of hte employers for the attrbutes of the graduates according to standandards of learning outcome was at the high level (=4.48). As for each attribute morals and ethcs were the most desirable (=4.75) the second highest level was interpersonal skils and accountabiliy (4.57) and the last one was the intellectual skills (=4.25) 3. The overall requirement of the ernptoyers for the 21st century skills of the graduates was at the high level (=4.43). As for each attribute the highest level was enthusiasm collaboration and thinking skills respectivrty (=4.634.58 and 4.54) The lowest tevel was the inquiry skills (=4.07). 4.The results of the research hypothesis were; 4.1 There was a significant difference between the employers with different employrment sectors (government and service business sectors) and the requirement of the graduates attributes. There was no significant difference between the employers with different working status and the requirement of the graduates attributes. 4.2 There is no significant difference between the employers with diferent employent sectors and working status and the requirement of the graduates attributes.

In FinFET-based VLSI designs heat issues from increase of driving current with temperature and self-heating effect profoundly influence the circuit performance and reliability. This work evaluates the performance of FinFET-based combinational circuits considering BTI stress and thermal effect of supply voltage and frequency variations. The proposed simulation framework is applied to selected benchmark circuits implemented with the 14-nm tri-gate bulk FinFET technology. The experimental results reveal that as temperature increases BTI aging delay increasingly worsens yet it is overridden by performance gain from the increase in driving current. We also prove that BTI degradation is dependent on power supply and frequency through their thermal impacts. Further we introduce a DVFS based power reduction approach that scales down the supply voltage of hot circuits to maintain the performance. The results show that power reduction yielded from the proposed technique is larger for all circuits working at higher ambient temperature (as large as 66% in some experimental circuits working at 20 oC above the baseline ambient temperature) with a slight decrease in BTI degradation.

The purpose of this research is to study assessment of safety in construction of building projects. The safety assessment form was developed by referring to the Ministerial Regulations. The safety assessment composed of 8 categories: (1) construction site perimeter (2) electricity and fire protection (3) crane (4) passenger lift and material hoist (5) welding (6) fall protection (7) temporary scaffolding and stairs and (8) personal protective equipment. Based on the safety assessment of the construction site the size of the large building exceeds 2000 m2 and height exceeds 23.00 m. in the Bangkok metropolitan has of 20 buildings. The average of safety is 80 percent. By construction site perimeter the highest average and the fall protection has the lowest mean. So all parties involved workers contractors and project owner in particular need to focus on safety work to prevention against falls from high in order to reduce the loss of property life company reputation including the morale of the work as well.
