การพัฒนาเครื่องอบแห้งข้าวเปลือกแบบไหลต่อเนื่องด้วยเทคนิคการแผ่รังสีความร้อนในแนวรัศมี
The objective of this research was to design and development of a continuous flow paddy dryer with infrared radial radiation technique. The prototype of dryer consists of two concentric circular cylinders cylinders which the paddy drying chamber is height of 1 m. The inner cylinder has diameter of 26.5 cm made from glasses and outer cylinder has diameter of 29.5 cm made from perforated (1.75 mm) steel sheet. At the center of cylinders installed 1200 w of electric infrared heater. A hopper was installed on the top of the chamber while 120 w of blower and paddy flow control were installed at bottom of chamber. The performance of the dryer in terms of specific energy consumption (SED) drying rate (DR) and quality of paddy i.e. head rice yield (HRY) and whiteness index (WI) were evaluated by drying 15 kg of paddy with initial moisture content of 23-26% (w.b.) by using the drying conditions of 80oC of drying chamber temperature 1.075 m3/min of air flow rate and 0.837 1.228 1.875 and 2.308 kg/min of paddy flow rate. The results found that paddy flow rate at 1.875 kg/min is the optimum condition because gave the highest DR lowest SEC and rice qualities (HRY and WI) closely to control.

Currently the edge image is regarded as important in the process of digital image processing. Because in the field of image processing in certain fields require lines or the edge of a complete description of the image in the photo itself. It is also essential to engineering. Most commonly used to calculate the difference like testicle to calculate the area between the point-to-point. Applied to select the coefficients to be used in combination with a new edge image clarity of the picture more. In this research will be trimming the edge blending image to compare the quality of the image obtained by the theoretical conversion web Paulette (Wavelet Transform) to demonstrate how to mix the new image it can provide the sharpness of the image the better. The assessment found that the proposed method can increase the contrast of the image. And maintaining data within the output video in its entirety

The research purposes were to analyze and search for wastes in the planning process and transportation of the automobile parts of a transport company in Samut Prakan using Makigami Lean and ECRS Techniques. The informants used in this study were the support staff working the planning process and automobile part transportation for the car assembly factory in the industrial estate Rayong Eastern Seaboard. Six employees from different work units took part in the in-depth interview as the research tool for the data collection. Statistics used in the data analysis including percentage and workflow analysis with related management tools. The study indicated that searching for the waste in the technical planning process with Makigami Lean and ECRS Techniques could help reduce the work time for 1060 minutes in each step.

Nowadays brake pad is a one of products that plays a role in the automotive parts industry and directly affects safety. Therefore there are many designs of brake pad for product development. The technique of reinforcing the layer in brake pads is another option for developing such products. The objectives of this research are to solve the problem of noise from brake pads using the material layer reinforcement technique and raise the quality of brake pads to use in the industrial sector. As a result the prototype brake pads with reinforcement techniques by means of damping layer were performed. Consequently the experimental work reveals that the brake pads with damping layer technique for brake pads can reduce vibration and also brake noise at the same frequency at less 10 percent at braking speeds of 50 100 and 130 km/h. Besides this technique can be applied to the production of brake pads in the same formula. However the prototype brake pads is still in the product development phase for testing in a variety of conditions both temperature factors and usage period

The research on development of pattern of cotton by using weaving technique in type of Mudmee fabric for metrosexual menswear by method of cutting and connecting has the objectives to : 1) develop pattern of cotton by using weaving technique in type of Mudmee fabric; 2) design of metrosexual menswear by using cutting and connecting from developed Mudmee cotton; 3) design the brand and packaging product to increase product value; 4) survey satisfaction of target group. The researcher studied by using Art Nouveau concept and by designing the cotton pattern by using Mudmee weaving technique numbering three patterns binding to make pattern woven to be fabric in order to make menswear in metrosexual style by using the method of cutting and connecting prototype consisting of one set of vest two sets of suits and two sets of overcoats as well as designing of brand numbering five types at the same time The researcher designed packaging product in five types using in surveying satisfaction of target group of thirty persons: Designer Merchandiser Graphic designer Visual merchandiser and person having fabric weaving experience by method of purposive sampling analyzing data by using statistics percentage mean and standard deviation. The study result was found that most respondents were female aged 36-40 years single status most have taste of female gender having income of 45001 Baht onwards. The educational level was Bachelor Degree. Respondents previously bought and used products and accessories for clothes from Mudmee cotton. The types selected to buy the most were vests bags and shawls respectively. The occasions in wearing the most of all were important festivals selecting to buy clothes and accessories for clothes from cotton by using Mudmee weaving technique in each occasion price 500-1000 Baht per one piece. Most persons participating in deciding to buy were friends. The sets of clothes for the groups wishing to design in sets of woman clothes. The result of satisfaction analysis of target group towards development of cotton pattern by using Mudmee weaving technique for metrosexual menswear by using cutting and connecting method it was found that target group had satisfaction in much level ( x= 4.16). The result of satisfaction analysis of target group towards design of metrosexual menswear by using cutting and connecting method it was found that target group had satisfaction towards the clothes in every type in much level (x= 4.26). The type which had mean of the highest satisfaction in the three first types including suit in type No.3 (x = 4.31); the second was vest type No.1 (x= 4.29) and overcoat type No.4 (x= 4.27). The result of satisfaction analysis towards format of brand and packaging product it was found that target group had satisfaction in much level having x= 4.23 and 4.30 respectively.
