In general the measured resistance with a digital multimeter. Users tend to be measured and then displayed on the screen to the user regardless of the value that is accurate or not. The value displayed on screen digital multimeter may be incorrect. As a result from wires access point measurement and other factor that affect to the value of measurement. Thus the study of factors that affect the measurement to get the accurate and more precise and also can be used in the operations. According to international standard quality system requirements for ISO are clearly on the meter or the measuring device must be calibrated and in the certificate specifies the gain calibration and the uncertainty of measurement. Therefore it is necessary to evaluate the uncertainty of measurement to comply with the standard splash. This thesis presents a study of the effect to the measurement resistance in 0.01 ohm to 100 mega-ohm by direct measurement for 2wire & 4wire Loading effect Using different kinds of conductors Thermal EMF and the stability of the resistor. Include the statistical analysis was used to estimate the uncertainty. From this study can be applied to measure the resistance in a variety of accurately and precisely.

This study examined risk measurement of 3 ASEAN capital markets during year 2009 – 2013. The objective was to study and compare risk of 3 ASEAN capital markets before and after integration of 3 ASEAN member countries : Thailand Malaysia and Singapore. GARCH Model was used for estimating risk in order to measure the daily securities price index of 3 ASEAN member countries The study split the data into two time periods the first period before integration starting from December 1st 2009 to December 1st 2011 and the second period after integration starting from December 1st 2012 to December 1st 2013. The results show volatility which is transferred by the stock exchange and the other stock exchange. The internal and external factors caused the volatility. The level and direction of volatility was likely to depend on balance between listed companies structure and economic structure of those countries characteristic of the stock exchanges and the majority of the investors of those stock exchanges.

The purpose of this research was characterized the noises at North Phra Nakhon campus Rajamangala University of Technology Phra NakhonThailand. The instrument of this study was instrument noises. Volume of noise levels were measured in terms of 15 hr and equivalent sound level (Leq 9 hr). 10 samples of noise levels were collected at Rajamangala University Technology Phra Nakhon from 10 stations. The results shown that the average noises volume of 9 hours were in range of 63.10 to 71.20 dBA by measuring station with highest mean of monitoring Station Building Civil Engineering in the area of Electrical Engineering and Mechanical Engineering were found 67.68 and 67.39 dBA respectively. The results of this study indicated that volume of noises in Rajamangala University of Technology Phra Nakhon were a little bit more than the standard of Pollution Control Department of Thailand and weren’t affected to teaching and learning in North Phra Nakhon campus.

งานวิจัยนี้มีวัตถุประสงค์เพื่อใช้ในงานวัดอัตราการเป็นสนิมของโครงสร้างคอนกรีตเสริมเหล็กโดยทั่วไป มักจะได้รับผลกระทบจากการเกิดสนิมของเหล็กเป็นส่วนมากเป็นผลให้กำลังของโครงสร้างคอนกรีตลดน้อยมีการพบการเสื่อมสภาพของโครงสร้างจากเหล็กเสริมเป็นสนิมอย่างแพร่หลายโดยเฉพาะโครงสร้างที่อยู่บริเวณชายฝั่งทะเล โดยสาเหตุสำคัญส่วนใหญ่ที่ทำให้เกิดสนิมมักเกิดจากคลอไรด์ซึมผ่านคอนกรีตเข้าไปถึงเหล็กเสริมและเมื่อคลอไรด์ซึมผ่านเข้าไปในคอนกรีตจนถึงระดับของเหล็กเสริม มีปริมาณมากเพียงพอก็จะทำลายฟิล์มที่ป้องกันที่ผิวเหล็กเสริม และทำให้โครงสร้างคอนกรีตเสริมเหล็กนั้นเกิดสนิมสะสมเพิ่มขึ้นเพียงพอที่จะทำให้เกิดหน่วยแรงและดันให้คอนกรีตเกิดความเสียหายเป็นผลทำให้กำลังของโครงสร้างลดน้อยลงจนไม่สามารถรับกำลังได้อีกและโครงสร้างจะเกิดการวิบัติในภายหลัง

This project deals with the application of microcontroller used for measuring the Q-factor of band pass filter. The procedure starts from the design creation and improvement of Q-factor and bandwidth of the filter. Solving the circuit filter frequency requirement the band must pass the filter. An instrument is necessary in the design of filtered frequency that shows the cut off at the rise edge and down edge searching the bandwidth and Q-factor of the filter. Finally the monitor will show all the values of every detail.
