Epoxy is one type of materials for adhesive. It was improved the strength by adding the filler such as iron alumina or silica. Generally the epoxy adhesive was mixed with iron for application in the metal adhesive. The mechanical properties were importance of adhesive. Because it was one factor for lifetime limit. The iron/epoxy was casted in the magnetic field which was alignment with surface of samples. The alignment of iron particles was induced with magnetic fields. The mechanical properties and wear behavior of samples were investigated hardness and wear test. It was found that the alignment of iron particles in the epoxy were improves hardness and wear.

Nowadays one of the automotive engineering is conductivity of brake pads playing a role in friction coefficient which means safety of customer. Thus thermal properties have been improved using composited materials. This project aims to study the conductivity behavior of 3 different brake pads which are supported by the company Compact International (1994) Ltd. For experimental works temperature based on brake condition was simulated from 200 to 400°C and cooled down from 400 to 200°C at 1 5 and 8 MPa of pressure respectively. By standard JIS D4413 testing condition of pressure was referred. The non-linear of conductivity value are calculated from the temperature under steady state condition. As a result of testing there are several of parameters effecting on the non-linear conductivity value. The brake pad that is a mix of high-fiber affects the fluctuation of thermal conductivity. At the same time lubricant in the brake pad cause the stability of conductivity value in different temperature range at the same pressure. On the other hand the brake pad mixed hi-copper inspires the narrow range of conductivity value in different pressures at the same temperature. Moreover the conductivity value as a mention is inversely proportion with the coefficient of kinetic friction.

This project presents the development of wearable device for logging cow behavior using IoT technology. This project aims to develop the device that can collect the cow’s behavior and to identify the current position of cow. The accelerometer and ultrasonic sensors are used to measure walking behavior and sitting behavior respectively. The current position of cow is measured by GPS module. The measured data will be shown and stored in IoT platform. According to the experiments the developed systems can measure the behavior properly with human acting as a cow. Moreover the developed system can show the current position of the cow and message when the cow is out of area. In the future it is planned to implement the developed system with the actual cow in real situation

Doi Inthanon Forest Nature Learning Area. Case study on relationship between learning and physical behavior of Doi Inthanon is a project that creates experimental architecture caused by finding a balance between learning behavior and the needs of the context to be consistent with the physical forest education on. Doi Inthanon in each area Which Doi Inthanon has a learning area that varies according to the overlapping of different nature in many forms according to the study area A. The first form is an open area in the community area. B. The second form is a semi-overlapping natural area. C. The third form is the natural overlap area. There is a form of usage based on the freedom of the user. Therefore the purpose of the project is education. To find ways and tools to design and create a space to connect users with nature Including being a learning area for those who are interested Using architecture as a link to learning relationships In order to be appropriate for the behavior of the physical user with the aim of studying this thesis topic as a case study In creating experimental architecture in each area of Doi Inthanon By using learning behavior of users in each area to study and experiment to form images To meet the needs of the area The interaction and consistency between the architecture people way of life and context

The purpose of this research was to study demographic factors and consumers’ behaviros of buying organic rice in Thailand and the marketing communications. This was a quantitative research collecting data from 4 0 0 samples by the questionnaire. The statistics used in this research were frequency percentage mean standarddeviation and chi-square test with statistical significance at .0 5 . The results showed that most of the consumers aged between 20- 29 were female Single employed in private companies graduated with a bachelor degree and had income THB 20000 – 30000 per month. Marketing communications were at a medium level Those are sold by Sales Representative public relations sales promotion advertisement and direct marketing. 1) The demographic factors Those accepted the hypothesis were age status and career. The Demographic factors those denied the hypothesis are were gender education and revenue. 2) Marketing communications factors in a magazine advertisement showed that buying behavior related to the frequency of monthly buying organic rice public relations through the agricultural market fair showed that the buying behavior related to the reason to select organic rice products Sales Representative who gave suggestions and demonstrate the correct organic rice cooking finally Sales Representative who informed the characteristic and differences of each type of organic rice. showed that the buying behavior related to The information of the organic rice products received through the media promotion and discounts the buying behavior related to the location to determine the buying of organic rice the direct market and customer contact via e-mail showed that the buying behavior related to the location to determine the buying of organic rice with statistical significance at .05.
