Design and development of solar cells in electric vehicle prototype intended to Design and development of solar cells in electric vehicle prototype Case study electric cars of Rajamangala University of Technology Phra Nakhon. The research process begins with the solar experiment model Solar Thin Film a bent size 19.2 x 9.5 cm technology has applications in Unmanned Aerial Vehicle install to a source of clean electricity generation using 80 Solar Thin Film Cells controlled by Arduino mega size 101.52x 53.3 mm Programming software by Arduino-1.6.9-Windows and Show the result at LCD Solar Monitor Charger from batteries store the electrical energy size 12V/28AH 6 pack for the results showed that such a circuit can charge electricity 5A to 1 hour and to expand the use of rechargeable battery electric prototype instead of using electric vehicle prototype from charging normally Requires 480 Solar Thin Film Cells in trial period hypothesis 6 hour/day. In term of investment evaluation simple payback period is expected to be 4 years. Considering sensitivity analysis it is found that the most sensitive factor is electricity cost cost Solar Thin Film and the cost of Evlink Fast Charge Solution respectively. The results of this study can be used to support decision making in design and development of electric vehicle prototype in the next generation more efficiently
การพัฒนาผลิตภัณฑ์ลอดช่องไทยจากแป้งข้าวกล้องสังข์หยด
The research was aimed to: 1) create a standard formula of Sangyod brown-rice flour Thai Lodchong 2) study the change during storage and 3) study the consumers’ acceptance. The physical properties chemical composition sensory evaluation and microbiological quality were determined. The study showed that Lodchong in which the substitution of Sangyod brown rice flour at 50% by weight of rice flour and 30% of arowroot flour for the total flour weight were used was most accepted in all aspects. The product has a slight physical conversion at 7 °C for not longer than 48 hours. All the microorganisms yeast and mold found were still safe for consumers and none of Escherichia coli was detected in the product. Nutritional analysis results revealed that 100 grams of the product contained 78.64 kcal energy 0.98 g protein0.07 g fat 18.03 g carbohydrate dietary fiber 0.71 g and 11.63 mg anthocyanin. For consumers’ acceptance it was found that the product was much accepted and 99% of the consumers were interested to buy the product at 22 bath per 180 ml cup.

Freight is major source of income of the State Railway of Thailand (SRT); which had revenues of one billion baht a year. The development of freight by rail system to be fart punctual and safe is important. Knuckle pin serves tension and shear stress in pulling Rolling Stock. Strength testing of Knuckle pin must be done by technical and engineering knowledge. SRT has 6000 Rolling Stocks; that means 6000 Knuckle Pin has been used and it is likely to increase due to the construction of the Double Track Project and the purchase of new Rolling Stocks. The efficient Knuckle Pin prolongs lifespan and SRT would have benefit on saving cost of maintenance and increase safety in the transportation of goods. This research is aimed at creating the understanding about the quality of the Knuckle Pin modeled Nat Mall. The pin would be test by Standard Test Methods for Tension Testing of Metallic Materialsand the Standard Test Method for Analysis of Carbon and Low-Alloy Steel by Spark Atomic Emission Spectrometry and Hardness Testing Machine and Microstructureto determine the cause of pin’s damage. This study will contribute the standardization of the quality of the Knuckle Pin which is used in Rolling Stocks of SRT.
