Nowadays one of the automotive engineering is conductivity of brake pads playing a role in friction coefficient which means safety of customer. Thus thermal properties have been improved using composited materials. This project aims to study the conductivity behavior of 3 different brake pads which are supported by the company Compact International (1994) Ltd. For experimental works temperature based on brake condition was simulated from 200 to 400°C and cooled down from 400 to 200°C at 1 5 and 8 MPa of pressure respectively. By standard JIS D4413 testing condition of pressure was referred. The non-linear of conductivity value are calculated from the temperature under steady state condition. As a result of testing there are several of parameters effecting on the non-linear conductivity value. The brake pad that is a mix of high-fiber occurs the fluctuation of thermal conductivity. At the same time lubricant in the brake pad cause the stability of conductivity value in different temperature range at the same pressure. On the other hand the brake pad mixed hi-copper inspires the narrow range of conductivity value in different pressures at the same temperature. Moreover the conductivity value as a mention is inversely proportion with the coefficient of kinetic friction.

The purpose of this research is to facilitate technology of limiting excess electricity from the source before supplying to the electrical appliances. The distribution of electricity by Metropolitan Electricity Authority (MEA) frequently exceeds the needs of households and factories due to the fact that the voltage has to be enough to send electricity to users who are located further at the end of the voltage grid lines. Most electrical appliances are designed to perform at optimum voltage of 220 Volt. The voltage optimization system controls the incoming voltage to fit the optimum voltage of electrical appliances which will reduce the overheating phenomenon and thus lengthen the lives of electrical appliances. It can save 8-14% of total energy being consumed and potentially reduce CO2 emission. This analysis system can be used for industries in the range of small to large companies. From the development of remote monitoring using a control via internet or 3G/4LTE the voltage optimization system showed practical power saving results of the reduced power usage and lengthen the lives of electrical appliances; that leads to reduction of emerging electricity resource eradication of natural resources increase the chance of marketing competition and energy sustainable

Freight is major source of income of the State Railway of Thailand (SRT); which had revenues of one billion baht a year. The development of freight by rail system to be fart punctual and safe is important. Knuckle pin serves tension and shear stress in pulling Rolling Stock. Strength testing of Knuckle pin must be done by technical and engineering knowledge. SRT has 6000 Rolling Stocks; that means 6000 Knuckle Pin has been used and it is likely to increase due to the construction of the Double Track Project and the purchase of new Rolling Stocks. The efficient Knuckle Pin prolongs lifespan and SRT would have benefit on saving cost of maintenance and increase safety in the transportation of goods. This research is aimed at creating the understanding about the quality of the Knuckle Pin modeled Nat Mall. The pin would be test by Standard Test Methods for Tension Testing of Metallic Materialsand the Standard Test Method for Analysis of Carbon and Low-Alloy Steel by Spark Atomic Emission Spectrometry and Hardness Testing Machine and Microstructureto determine the cause of pin’s damage. This study will contribute the standardization of the quality of the Knuckle Pin which is used in Rolling Stocks of SRT.

The purposes of the study on influence of motivational factors towards on organizational loyalty and performance of operational personnel in health science group in an autonomous university were to 1) study the influence of motivational factors on organizational loyalty among operational personnel and 2) to study the influence of motivational factors on the performance of operational personnel. The questionnaire was applied for data collection with the reliability acquired through Alpha Coefficient of 0.982 which was used to tryout with 30 people and collect data from 124 operational staff in health science group in a state-run university located at Chulapat building (source: Office of Personnel of Faculty of Allied Health Sciences Faculty of Nursing Faculty of Nursing and Faculty of Sports Science January 31 2017). This research is a descriptive research. The data obtained from the researchers questionnaire was analyzed by statistical analysis program including percentage analysis is used to analyze the individual factors mean used for interpreting various data and standard deviation to interpret data in various areas and multiple linear regression for testing the hypothesis as well as Pearson correlation. The research revealed that the hypothesis testing on motivational factors towards organizational loyalty and work performance of operational personnel in health science group in an autonomous university included 1 ) work success 2) work progress 3) acceptance 4) responsibilities and 5) job description while supporting factors included 1) salaries 2) advancement opportunities 3) relationships with others 4) status 5) policy and administration 6) work environment 7) work security and safety which influenced on organizational loyalty and performance of operating personnel in health science group at the 0.05 level of significance.

The purposes of this research were to design and create dyed silk yarn and cotton yarn machine for community enterprises of Ban Na Pho woven group Na Pho district Buriram province. All materials were made of stainless steel and the principle of rotation of the yarn skein which was hung with spindle yarn inside the dye tank. Dyeing process began by mixing color tanks in the exterior size for diameter ๓๐๐ mm. Adjust the temperature inside the dye bag by the boiler was attached below. Using pump in dye tank for rotating the heat with stainless steel pipe in ๑๑/๒ inches and ๓ inches x ๑/๒ inches and the rectangular tank was ๖๐ cm. wide ๙๐ cm long and ๑๖๐ cm. high. It had ๕ mm. of plastic lid cover in front of and a channel that looked at the attachment of color yarn. The lid had ๒ levels adjustable lift spring lock and ๒-axis spindle yarn. It was triangular shaped drilled holes spray to ๑ mm. on the spindle with a diameter of ๑๕ cm. and ๖๐ cm. long rotating at ๑๐ rpm strength by using electric motor size ๐.๕ HP used ๒๒๐ volts. It could be rotated left and right with the gear ratios around ๒๐:๑ ๒ adjustable that were automatic with programming on the control box and simple pattern. the spray dyed paint had ๑ liter water pump to control pressure valve for opening and closing to dyed water flow regularly by the heat from the LPG gas with a head size of ๓๐ cm. and adjust the temperature up to ๑๒๐ Celsius degree. It was showed the temperature measurement of water dye with pressure gauge and temperature gauge. The efficiency of this dye can be dyed silk yarn and cotton yarn per ๕ kg. to ๑๐ kg. which was a medium-sized textile production to the local community enterprise and applied in the preparation of yarns before dying such as peeling glue and bleaching.
