The purpose of this research was to construct the rotating bending fatigue testing machine for metal material to find out the built-in machine performance and compare it with machines that meet international standards. The machine built into a compact machine using weight knob for a heavy load in testing. It can test the force range 50-300 Newton (N) the motor is a 1 HP transmitter with a speed of 2800 rpm. Start by pressing the Start button to release the weight that sends power to the workpiece and attend a sensor counting is available to detect the lack of testing material. For the efficiency performance of the machine uses 10 piece steel shafts diameter of 8 mm according to the standard of the material fatigue tester by independent end bend rotation. For testing to compare with the test international standard machine also uses 10 piece steel shafts using force 150 N. For the analysis to test statistical hypotheses with the Minitab computer program at the significance level of 0.05 it was found that the values obtained from be made the rotating bending fatigue testing machine for metal material there is no difference with standard machines from statistically significant. All values are within the set limits. In conclusion the machine was created to be as effective as the international standard machine.

This project has the objective to study and design on ladies costumes by students about Maria which is taken as a basic concept in design and application in development of apparel for ladies by research information format and costume history of Madonna and has studied research data formats Jean Paul gaultiers costume Couture spring/summer 2007.Information on the development pattern of the dress in the design that can be worn. From the study data. The study was conducted using a descriptive analysis. The model analysis showed that the Virgin Mary costume. Form of apparel. Most are white. As symbols of chastity devices. Purity and happiness. This can be reproduced in the costume ladies. Analysis patterns costumes Jean Paul Golden Poitiers series of different techniques out. Which are both set to true and wearable art design. Can be taken as a guide to adjust. Pattern to modify the model to wear it. The results showed that Approach to solving problems is to use fashion as a medium to bring faith in Madonna. Story of love and sacrifice wholesome a meal as a basis all of these reflections is the image of being together in society. In the thought process of designers.

This project has objectivefor study style Fencing Sportswear and for studytype of lady costume type of business party. Population foe study is Fencing sportswear use in competition of Thailand open 2013.Sample group for study is Fencing sportswear use in competition of Thailand open 2013.This Studyfocus on Fencing sportswear’s Gransports company in 3 from 1.Fencing foil set 2.Fencing epee and 3.Fencing saber Study information Fencing sporstwear use descriptive analysis. The result of analysis Fencing sportswear found condition of Fencing sportswear’s simple andgraceful in design bring modern style and gentlestripes after movement of sport costume. Design is useful for daily life. The result found solving need to develop lady working costume’s style for appropriate with limit time andhustle therefor should pick clothing able to wear in working and party at the same time.Combination with Fencing sportswear to make it’s graceful modern support lady costume able to wear in daily life and more perfect.

This project presents the simulation of a three-phase generator. The aim is to study and analyze the condition of the generator functions. By simulating the operation of the generator used in factory which use this generator as a backup power source to replace primary power source of electricity-supplier. In this test can start or stop the generator to determine the parameters at that time. The generator is used when the main electrical power distribution error and the generator is disabled when electric power system of electricity-supplier back to normal.

An MV-algebra G is an abelian monoid (G0+) with the operation * satisfying (x*)* = x x + 0* = 0* and (x *+y)*+y = (y*+x)* = x . Let G be an MV-algebra. A function f :G →G is called homomorphism if f (x + y) = f (x) + f (y) and f (x*) = (f (x)) * for all x and y in G . In this research we study the homomorphism and isomorphism theorem in MV-algebra.
