For modern processors permanent and transient errors due to increased temperature and single event effect continue to intensify as device technologies scale down to small nanometers. While many researchers have proposed efficient methods to limit one of these two problems those techniques may worsen the other reliability aspect. In this project we introduce a novel leakage reduction approach for long-term reliability improvement which considers the impact of shortterm reliability effect from soft errors. In particular we firstly employ body bias tuning to reduce leakage and further investigate its impact on delay and soft error rate of the circuit. It has been discovered from our experiment that use of reverse body bias to control leakage can raise the soft error rate in addition to the delay performance. We therefore integrate several effects of body bias into the proposed leakage reduction technique. The experimental results show that our approach provides satisfactory leakage reduction with confined soft error and delay degradation in 32 nm high-k/metal gate benchmark circuits.

Nowadays container of alcohol for warm food is produced from raw material of alloy mixture of tin chromium and manganese. When the container is heated with the flame temperature at 300 c which it is burned about 10 minutes. The container is transformed into trash that it’s difficult to disintegrate for destroying the environment. This reason is that the sawdust is taken for useful and alloy substitute. Manufacturing container from the sawdust on alloy with alcohol gel substitute for warm food the process of forming is essential that mold extrusion and compression mold are designed appropriate to size shape of workpiecesafedurablesuitable work including preparing forming sawdusttest for burningpreparing synchronizationdesign work and selecting material for mold. The result of project revealed that the burning was taken about 26 minutes per piece while metal container had 15 minutes. Furthermore sawdust container was about 73.33 percent and the temperature of combustion higher than metal container about 51.88 percent. Sawdust container costs 2.45 baht per cup and lower than 51.00 percent whereas metal container costs 5 baht per cup. The rate of precipitation into process of biodegradation container from sawdust and water showed that the rate of good biodegradation was depended on precipitation into process of biodegradation.

The aim of this research is to create the center of mass testing machine for vehicles with maximum mass 3000 kilograms. By the performance of this machine is able to determine the center of mass 3 axis by horizontal longitudinal and vertical. On the other hand the verities of mass from 50 to 100 kilograms and the several of weight distribution at horizontal and longitudinal are applied to the condition of testing for reasonable to the position of the center of mass. The result of research discovered to the performance of center of mass tester was activated following to test conditions. Furthermore the weight distribution at longitudinal was the highest effect to the horizontal center of mass. By the way the value of weight distribution at horizontal is more effects to the longitudinal center of mass. Moreover increasing of mass was impact to the vertical center of mass and it’s independent to the position of weight distribution.

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 longitudinal plane are affected to the center of mass and absolutely influence at the right wheel on the front axle. 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 weight distribution on the front axle was decreased lead to mass distribution on longitudinal plane.

The aim of this research is to study the brake proportional affected to vehicle stability. Braking performance and vehicle stability testing are the main of research purposes. Otherwise learning research center and new researcher in automotive engineering are the minor research objectives. The results of research discovered to the braking performance depend on driver behavior. By the minimum deceleration was appeared on the non-proportion in front axle with braking ratio 0:100. In term of vehicle stabilities yaw and pitch moment are normally occur by the driving behavior. But the sideslip is an absolutely effect to vehicle handling. With the braking ratio 100:0 there is the highest risk for controlling a vehicle cause of the wheels were locked-up condition in the rear axle. Therefore the value of the sideslip was exceeded with the criteria. Furthermore these project researches were got the learning research center and the new researcher in automotive engineering field.
