The aim of this project is to study the fuel consumption from the effect of tire pressure and tray volume. In order to tire pressure is consist of 2 conditions by: Road test and Roller test Bench. Their test is classified by 3 cases: standard tire pressure lower standard tire pressure and upper standard tire pressure. Furthermore the lower and upper standard tire pressure was compared with standard tire pressure. In case of seal and unseal of the tray volume was test with 2 postulates by Road test and water tunnel (model). The results of experiment with 3 cases of tire pressure found that the lower standard tire pressure (25/37 psi) given to the maximum fuel consumption when compare with standard tire pressure 4.6%. While the minimum fuel consumption is upper standard tire pressure (33/45 psi) or 1.29%. Furthermore the trend of those conditions was in the same direction. For the result of test in term of seal and unseal of the tray volume discovered to the fuel consumption in case of seal is lower than unseal of the tray volume 1.63%. And the result of test of the water tunnel has been the same direction with the Road test.

The objective of this fashion thesis was to study womens clothing design in party wear style inspired by Thai Lacquer Art (Lai Rod Nam) in Ayutthaya era. The outstanding points of Ayutthaya era’s Lacquer Art: appearance and pattern of lacquer decorating Tripitaka cabinet were applied in connection to Khon costumes to create and design womens clothing in elegant and tasteful party wear style. The instruments included Ayutthaya era’s Lacquer Art analysis form consisting of layout and pattern placement and color use Khon costumes analysis form consisting of costumes layout focusing on physical nature and overall work analysis. The results of this study showed as follows. The author applied Thai Lacquer Art pattern decorating Tripitaka cabinet in Ayutthaya era including Kanok Pleaw Kanok Ruang Khao Pun Pruksa and pattern in animal figures to redesign and reorganize the work. Digital printing technique was use to press the pattern on the fabric to be applied to Khon costumes structure. This study focused on the design and development of clothing that is modern while remains the identity of Thai Lacquer Art.

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 occurs 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 aims to study the costume designers hippie style was inspired by a native tribe Lisu in Mae Hong Son province . Get ideas from hippie clothes. The study was led by the appearance of the hippies in the 70s applied. Such a combination of cloth into garments by tribal technique of cloth Lisu tribe is to cut the fabric. Cloth Lisu tribe is a unique fabric is made with a variety of colors. Fold the fabric diagonally line by line. The need to fold into a rectangular or triangular piece by piece then bring the two sides together fold then bossed by hand one by one. And integrated into a fabric. Colorful The distinctive characteristics that are unique in design. The instrument used in this study. An analysis of patterns of cloth Lisu tribes. By the analysis of two 1. Patterns 2. Colors include a focus on the physical aspect. And image analysis the overall portfolio. To be creative costumes. The study found that Pattern of cloth Lisu tribe is overlapping geometry as a pattern. With the use of warm colors and cool contrast to the dominant pattern. Thus the study took the data to the application in the design model focusing on bringing hippie motifs applied in costume.

Nowadays an automotive industry steadily has been growing and playing a major role on economy development for many years. The crash box is one of the most important parts for safety but it was found that the crash boxes manufactured domestically are not met international standard requirements. This is due to process and material limitation. This process for automotive safety test requires high budget and there is unclear approach for specific test. Therefore a study of crash boxes referred to energy absorption project was conducted as the alternative materials for product. Consequently this project was aimed to design and test crash boxes which made from the diversity of the alternative materials such as aluminum aluminum reinforced by foam resin reinforced by fiberglass resin reinforced by water hyacinth and resin reinforced by water hyacinth and husk. In addition it was also emphasized in studying energy absorption behavior and physical deformation of crash boxes after dynamic and static energy being applied. The experimental works were applied for these tests in partly referenced to US NCAP and ECE R29 standard for automobile collision test. Testing all types of crash boxes indicated that the aluminum reinforced by foam type was able to absorb energy at 189 MJ/m3. It is higher than resin reinforced by water hyacinth and husk at 1 MJ/m3 as 188 times. Furthermore the comparison of the energy absorption (per unit volume) between the aluminum reinforced by foam type and the steel type from the previous project equivalent 20 MJ/m3 found that it is 8.45 times of difference. While the front impact test was not successful because the size of crash boxes was not suitable for the energy volume. It was a cause for non-available calculation of energy absorption value.
