Admittedly a disc brake plays an important role in the auto part industry since it concerns directly with safety. Therefore the wide range of disc brake has been designed in order to develop its heat ventilation. Thus this project has designed a back-vented brake disc which is difference the current one (front-vented) and tried to create the test to find out the temperature diffusion of the disc brake with the hope to evaluate the coefficient of the heat convection varied by the temperature changing in both kinds of brakes under the forced heat convection in the steady condition. However the steady heat conduction and radiation value will not be counted because it is insignificant. The JASO C406: 2000 Standard is adopted as a guideline in the test. The outcome coefficient of heat conduction will be used in the simulation via the Finite Element Method (FEM) in order to study the temperature diffusion and heat ventilation of both kinds of brakes at each temperature level. Consequently the experimental work reveals then the heat convection coefficients of both kinds are unidirectional. The heat convection coefficient of the front-vented disc brake is 4.40 % in average higher than that of the back-vented disc brake. From the simulation the front-vented disc brake can ventilate the heat better than the back-vented disc brake at 3.02 % in average. It can be summarized that the front-vented disc brake has more temperature difference than the back-vented disc brake. Hence the front-vented disc brake likely gets more stress from the temperature than the back-vented disc brake and might be damaged during the operation more than the another type. Therefore this is tendency that the back-vented is safer than the front-vented brake disc for usage.

The aim of this research is to study the varieties of weight density distribution affect to the center of mass and vehicle stability. The weight density distribution tester was designed and changed the position of mass. Base on the center of mass is main points of vehicle stability. On the other hand FMCSA standard was applied to field test for considering of the brake performance and vehicle stability. The results of research discovered to the mass distribution on horizontal plane and fixed position Y1 are absolutely influence under an increasing 50 kilograms of mass condition. For the mass distribution on longitudinal plane and fixed position Z2 and Z3 are affected to the increasing of mass 100 and 150 kilograms respectively. Otherwise under an increasing of mass 200 and 250 kilograms there is non-influence to the weight density distribution. In term of the braking performance it’s depends on the lateral mass distribution especially the center position of mass installed on longitudinal and horizontal plane and close up on the front axle (Y2). For the vehicle stability results the position (Y2) is the highest influence for yaw rate and sideslip. Otherwise the position (Y3) or the position of mass installed on longitudinal plane and nearly at the left wheel on the rear axle. Additionally wheel lock-up condition was appeared on the front axle only. Because the behavior of the weight distribution on front axle was decreased lead to mass distribution on longitudinal plane.

The purpose of the project is to study basic recipe of khanom sōmmanat by selecting 3 recipes to determine the acceptability of the teste. Which use zuek in 3 levels that are 5 10 and 15 percent of weight Baked coconut. The experiment is analyzed by Randomized Complete Block Design (RCBD) to evaluate the sensory quality in appearance color flavor teste texture and overall preference. The sensory in evaluation is tasted by 9 – Point Hedonic Scale from 80 persons. The instructors and student of the Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon. After that the analyzed by analysis of variance (ANOVA) and of Least Significant Difference (LSD) statistically significant level 0.05 The research shows that 10 percent of zuek in the best substituted amount as an ingredient of khanom sōmmanat by the appearance color flavor teste texture and overall the average points are 7.80 7.68 7.86 7.96 7.95 and 7.84 respectively. The analysis of variances and Range Test are significant difference in the level of statistical 0.05.

The objective of this research to study the basic formulas of Thai egg custard type of cutting corn kernel physicals and chemical properties of final product of this research by -9 point hedonic scale of 30 examiner laboratory. The results show the basic formula of Thai egg custard be recognized to study in the next step. The results show the basic formula of Thai egg custard accept on the like moderately (7). Then conduct 3 type of corn kernel are whole slide and chop for choose by 30 examiner laboratory. The examiner choose slide of corn kernel in enhancing of Thai egg custard at 20% 30% and 40% by total weight. The result show that the % of enhanced slide corn kernel was significant in acceptance and color liking (p<). The texture profile analysis of sweet corn Thai egg custard75.98 to 111.08 of firmness and-30.72 to-35.04 of Cohesiveness. The chemical composition of 20% slide sweet corn kernel Thai egg custard were 243.86 Kcals of total energy 95.95 Kcals of energy from fat6.25 of protein10.66 of fat0.91 of ash29.87 of carbohydrate and 1.70 of crude fiber. However enhancing of sweet corn in Thai egg custard can be extra Consideration of chemical composition of ingredients such as sugar and starch for acceptance of Thai egg custard of these features may affect to physical properties such as in color and texture of production should be intensive studied.

The objective of shockball subprement malekcaboke is study base formula in doing shockball and study malekcaboke quantity that is appropriate of malekcaboke addition appeared 4 steamed level 0% 15% 30% and 45% of all compound weight lay plans experience like model to random in block completed (Randomized Complete Block Design RCBD) by use 40 person come to do test way sense evaluation by points alms like model 9 the level (9-Point Hedonic Scale) lead come to see the average analyses the vary and compare with the difference of the average like model Duncan’s New Multiple Range test (DMRT). From formula base education meets the 30% malekcaboke of all compound weight person teste testily admit in the sense of color smell snack the meat touches and the liking generally at the most when bring analyse the vary and compare with the difference meets that color side the meat touches and the liking generally have the difference important implily statistics way that 0.05 part side smell level that have no the difference important implily statistics way that 0.05 level.
