The objectives of this research are to propose a proper model for detecting defective machines in auto parts factories to apply the proposed model to the defective product data and to investigate the factors influencing on the machine producing defective products. A Bayesian hidden Markov model (HMM) is adopted. The results show that if the number of defective products increases the machine will be in the hidden bad state. The probability of changing from a hidden bad state to a hidden good state is higher than the probability of changing from a hidden good state to a hidden good state. The highest probability that the machine will be in a good state is at the work process 4 followed by 1 3 and 2 respectively. The highest probability that the machine will be in hidden good state is at the Worker no. 10 followed 9 3 12 7 2 1 6 11 4 8 and 5 respectively and The highest probability that the machine will be in the hidden good state is at the product type 1 followed by 2 and 3 respectively.

This research aims to apply the principle of stochastic process for modeling. The parameters are estimated using Bayesian methods. The monthly average real price of paddy rice 15% and yield of paddy rice in Thailand were studied. The price and the yield of paddy rice which are time series data consisting of four components autocorrelation an exponential cumulative distribution function for trend outliers and two different types of seasons: the dummy seasons and Fourier function seasons. Writing algorithms programming in OpenBUGS and evaluating the performance of models from simulation programming in R were conducted. After that Bayesian methods with dummy seasons and Fourier function season were compared using RMSE MSE and MAE as the criteria. The results show that the Bayesian model with an exponential cumulative distribution function for trend and dummy seasons give the lowest RMSE MSE and MAE for both model fitting and model validating.

This research aims to develop the natural-rubber floor tiles mixed with high fineness ethylene vinyl acetate plastic wastes (EVA plastics) from the factories. The study use natural-rubber STR 20 at 100 phr with various contents of EVA plastics (e.g. 0 5 10 20 40 and 80 phr) and then mixed with chemical substance at constant ratio include zinc oxide at 5 phr stearic acid at 2 phr mercaptobenzothiazole at 0.5 phr diphenyl guanidine at 0.2 phr and sulfur at 3 phr. The samples are ground by two-roll mill and formed by compression molding at 150 degree Celsius with 30x30x0.2 cm of dimension. The properties of the natural-rubber floor tiles are tested under ASTM standard. From the results it is found that the natural-rubber floor tiles mixed with 10 phr of EVA plastics is the suitable ratio for using as the rubber floor tiles in building. This ratio can increase the hardness tensile strength and wear resistant properties and decrease the density and thermal insulation properties when compare to the natural-rubber floor tiles without EVA plastic.

The purpose of this project is to study ‘ Lady costume design’ by using art of Frida Kahlo. We bring his concept and idea by using printing technique to design our ready to wear lady costume which make our product unique and outstanding. We separate his art works into 2 sections : Style technique colour and overall analyze his art works as a basic information for lady costume As the results of this study found that Present in the disabled in society rather Although most social acceptance. But there are some people that can not work. And creative things with it. The study therefore is likely. The idea that fashion is a medium of expression to people in society that people with disabilities can not work. And creative things with it. And to recognize the work of the disabled without losing the regular ones. And the people in turn to provide the opportunity to work with people with disabilities. By the art of Frida Kahlo apparel in the works.

The project of design and development of textile product using Thai Song Dam’s stitching technique at Supanburi provinces. “Nowadays it was difficult to find someone who loves weaving; however finding someone who loves stitching was more difficult. The designs of stitching pattern were altered by trend; however they still kept in their identity” Mrs. Lamduan Konthong a specialist in Thai Song Dam’s embroidering style said. According to the questionnaire regarding the requirement of the sample it showed that the sample was interested in the textile products for living room decoration such as a backrest pillow a decorating table runner and a lantern. Thai Song Dam’ stitching technique and “Kor Kood” pattern should be applied with the design of the designated products. To find the appropriate fabric for stitching the experiment was done by stitching of “Kor Kood” pattern on the following type of cotton silk linen hemp and knitted fabric. The chosen one was linen fabric because of its light weight good dimensional stability. To create the model of the products and find the appropriate pattern for stitching the pattern was designed by the concept of Art Nuvo characterized by the appearance of woman. From the questionnaire it was found that the satisfaction of the sample regarding the design of the Thai Song Dam’s stitching in textile products were as follows; 66% kept in the identity of Thai Song Dam 72% style the products of Thai Song Dam 58% Thai Song Dam style the design of the products characterized by Art Nuvo 50% suitable the composition of the pattern of the products 74% suitable the whole pattern design of the products 64% suitable the colors of silk stitching on the products 60% suitable the use of colors of the products 60% suitable the size of the products and 62% suitable for the purposes of using.
