ออกแบบและสร้างหุ่นทดสอบการชนของรถจักรยานยนต์ภายใต้สัดส่วนโครงสร้างของคนไทย
The aim of this research is to design a prototype of a male dummy chest for motorcycle crash tests. The primary criteria discussed in this study are based on the unique features of Thai ergonomic body sizes with an age range of the highest fatal rate and the fundamental design of the Hybrid III 50th percentile male crash test dummy. A comprehensive experimental study of crash behavior of the prototype undergoing axial compressive loading is performed using the mutual procedure of cadaveric chest testing. For design criteria the largest chest deflection of 80 mm the maximum acceleration of 38.47g and the absorbed energy of 178.369 Joules are considered in the experiment. The obtained results show a good agreement with the experimental data of other researches in which the capability of the energy absorption depends on impact velocities. In addition the energy absorption capability of this prototype can accurately assess an injury level under AIS 3+. For this reason the first prototype of a male chest dummy is particularly suitable for an assessment of a lower serious injury level in a motorcycle crash test.
การเฝ้าระวังการเกิดไฟไหม้ในพื้นที่บ่อขยะโดยใช้โดรนและเทคโนโลยีการรับรู้ระยะไกล
This research was the application of Unmanned Arial Vehicle (drones) in conjunction with remote sensing technology to monitor the occurrence of the waste dump site fire. The research began with designing and developing prototype tools to collect data from the field site. After the tools were tested they were used to measure gases from the dumping sites. After that the field observation was performed in Nonthaburi Province Pathum Thani Province and Pha Nakhon Si Ayuthaya Province. The final step of the research was to collect the data of active fire hot spot and image from MODIS system satellite covered the area of Nonthaburi Province Pathum Thani Province Pha Nakhon Si Ayuthaya Province and Samut Prakan Province in the period of 1 November 2017 to 31 October 2018. The result showed that the developed drone and the prototype gas detection units worked as designed. The result of gases measurement by the tools were similar to the references equipment. The field observation showed that the dumping site mainly composted of plastic organic matter and cotton which up to 74.9 percent in total. This indicated the factor that influenced the dump site gas generation. Based on the combination technique in the research it could be concluded that Drone and Remote sensing technology were the compromised technology for monitoring fire from the municipal solid waste dump site area.
ศึกษากระบวนการทำเครื่องปั้นดินเผาโดยใช้ประโยชน์จากกากกาแฟเหลือทิ้งเพื่อพัฒนาสู่การออกแบบเชิงสร้างสรรค์
The research objective of this research 1) study and experiment the waste of coffee waste to create a creative advantage 2) study and design pottery handicraft products using the waste of waste coffee material 3) develop and build on existing local knowledge that is valuable and worth a lot more Research results conclude that the trial in removing waste coffee residue as a clay mixture can make the product more beautiful in terms of texture and color tone. Which is very beautiful and has a higher value. Which when burned in the ideal temperature. The surface of the pottery will have a rough texture uneven and color in the color tone Din. Can develop into creative design. The design of pottery and handicraft products using the waste of coffee residue into creative design. The concept of design is to take into account the uniqueness of endowment beauty usability. Manufacturing Processes The design pattern is derived from three forms from which the researcher attaches importance to shaping the design of the pottery. The shape of the design is derived from the uniqueness of Thailand. The result of the design is a decorative sculpture home size is appropriate to the home decoration of all types all the beauty resulting from the local wisdom. Production experiments showed that It is a way to add value to your product.
การพัฒนาผลิตภัณฑ์ข้าวสังข์หยดพองไร้น้ำมันผสมเมล็ดพืช
This research had the following objectives: 1) To compare roasted and fried Sangyod rice grain products. 2) To find proper proportion of puffed Sangyod rice grains to other seeds. 3) To find storage life of puffed Sangyod rice grains mixed with other seeds product. 4) To calculate cost of production of oil free puffed Sangyod rice grains mixed with other seeds product. Results found that physical properties of roasted Sangyod rice grains puffed and expand better than the fried ones. Consumers preferred the roasted grains to the fried oned because less oil was consumed which was good for health. In developing puffed Sangyod rice grain product Consumers accepted the second formular of 50:50 proportion of puffed Sangyod rice grains to other seeds better than the other proportion of 30:70 and 70:30. The results were statistically significant. This formular was used in storage life study. Results found that the product can be kept 7 days at ordinary room temperature Microbial growth was observed every two days. Mold and yeast counts and water activity were studied. No mold nor yeast were found in day 0 water ativity was 0.58. No mold nor yeast were found for 7 days. Cost of production of puffed Sangyod rice grain mixed with other seeds product was calculated. The material cost was 95 Bahts. 30% processing codt was 29 Bahts for 50 pieces of product. The average cost per piece was 2.10 Bahts.
การพัฒนานวัตกรรมรูปแบบกระเป๋าสุภาพบุรุษ จากผ้าทอกะเหรี่ยง จังหวัดลำพูน
The purposes of this research were: 1) to developed innovative style Gentleman Bag from Karen Cloth Lamphun and 2) to transfer the technology from innovative style of Gentleman Bag from Karen Cloth to develop the community product standards. A sample was selected from tourists in Lamphun drawn from Purposive sampling including 100 people and 20 Karen weavers from Phrabat Huai Tom Community Na Sai Subdistrict Lamphun Province. The instruments used in this study were satisfaction questionnaires of Gentleman Bag from Karen Cloth Lamphun and 5 styles of products from Gentleman Bag from Karen Cloth Lamphun. The statistics used in data analysis were percentage mean and standard deviation. The results of this research showed that most of the tourists are male aged between 36 - 45 years civil servant and state enterprise employee. The satisfaction with the Gentleman Bag from Karen Cloth was in the highest level the highest average was the exquisiteness of the product followed by the durability of the product the size of the product is suitable for use decorative materials and product performance. The transfer of technology from the innovation of the gentleman bag from Karen Cloth Lamphun province was to develop the standard of community products found that weavers in Phrabat Huai Tom Community Group Na Sai Subdistrict Li District Lamphun Province have knowledge and understanding of prototype of gentlemans bag products from all 5 styles of Karen weaving. So the pattern can be cut and sewed correctly according to the prototype. And has guidelines to set standards for products for use as a basis for certification and quality assurance for consumers.
