การพัฒนาเงื่อนไขขอบเขตของแบบจำลองน้ำตื้นเพื่อขยายการทำนายมรสุมตะวันออกเฉียงเหนือ
The shallow water model is a mathematical model was developed from the shallow water equations. It consists of the continuous flow and the momentum equation of non-linear in the x-axis and y-axis. The boundary conditions of the model is the cyclic continuity from east to west and the open boundary conditions from north to south. The northeast monsoon forecast by the shallow water model can’t be predicted in a long time period because the boundary conditions of the model has a problem. Thus improvement the boundary conditions of shallow water model by using wall boundary condition from north to south. The results of this research to found that the shallow water model can correctly forecast the northeast monsoon period in the long term.
การออกแบบเครื่องทอผ้าแบบยกดอกพิเศษด้วยเครื่องแจ๊คการ์ด (JACQUARD)เพื่อพัฒนาผลิตภัณฑ์ชุมชนเชิงนิเวศน์เศรษฐกิจ
The research was an objective to study the weaving proves in the central of Thailand. IT was focused on problem study and design consumption by special loom as jacquard for improving the weaving techniques. This research not only data analysis ofr jacquard production but also transfer knowledge as economic efficiency product by workshop. This study was an experimental development research by purposive sampling. The information were surveying from ๓ groups. The first was ๒๕ people what using native woven in north central of Thailand as Nern-kham woven cluster at Nern-kham district Chainat province. The second was ๒๕ people what using flying shuttle woven from Wat nam Tao in Ma-ha Rat district Ayutthaya province. And ๕๐ people what using produced loom. The results were evaluated in jacquard satisfaction as reduced time production by using ๑๒๐ heddles ease of jacquard setting up that was delicate and versatile styles on native woven such as Yok-Dok Yok-kit Teen-jok Praw-wa and the other native styles. The heddles tool was Rectangular and C-type steel whatever it was greater durability material. The additional this product had the returnable storage cards that they were controlled by cylinder. The working area was individual adjustable. However the combination of this product into the traditional loom weaving must be controlled by specialist. This produced machine was ease movement and reduced torn warp yarns. The fabric was rolled by hand lever to turn the both side together. The heddle was raised by foot lever in rhythmic weaving. The produced jacquard was a similar production cost as the same product but it had better efficiency and reasonable price. It was suitable for new weaver thus had a background in basis weaving for making the high efficiency production and good quality product. Thus the machine had an axil and gear for reed locked and hit regularly width fabric. The summarize research concerned with process technique weaving process. The main was jacquard system of heddle lift system. It promoted the development knowledge for semi-automatic loom weaving thus motor and electricity combination. Moreover the design of jacquard for loom weaving was basement knowledge of developing the new equipment tools pattern for textile product in ecology economical furthermore.
