<description>A designed object tracked by mobile robot using image processing
Waiyawut, Wanapun
In present, there are widely use robot in many fields. Mobile robot can help us in several task, such as moving to toxic area, risk area or explosion area, mine. Movement control can be used in many ways. This paper proposed mobile robot that movc by wheels. It move to previous defined picture. By using small camera process an images and check it that is the previous one by using neural network. If it is, robot will move toward to that picture. The movement is in flat plane. If that defined picture is not in center, robot will move to left or right depend on its position until it is on center. This paper proposed image processing only.

<description>Control system to store electricity from solar cells using super-capacitors controlled by embedded system
Waiyawut, Wanapun
To store electrical power from solar cells are generally used battery as storage. Recent development in capacitor technology, achieves with higher capacitancc, smaller, and low cost, especially dcvelopment of a supcr capacitor (doublc laycrs). This research study used a super capacitor to store electrical power from solar cells. The results show that super and electrolyte capacitor can be used without battery, with more power density, and fast charge. But capacitor discharging must be controlled. The important disadvantage is super capacitor is used with low voltage and high rate of charge leakage. In case of electrolytic capacitor can use with higher voltage, low rate of charge leakage but lower capacitance.

<description>Research on green plastering materials
Rukzon, Sumrerng; ngoenphrom, Niroj; Nicomrat, Duongruitai
This research studies the potential for using waste ash from industrial and agricultural by-products as a plastering material. This paper presents a study of the water requirement, compressive strength, flexural strength, normal consistency, setting time, and air content of plastering material containing classified fly ash (FA) and ground rice husk ash (RHA). &#13;
Fine fly ash and fine rice husk ash have a high potential to be used as a good pozzolanic material. The use of finer pozzolan results in a stronger and denser mortar which is due to better Q!spersion and filling effect as well as an increase in the pozzolanic reaction. Fine fly ash and fine rice husk ash can be incorporated into mortar as replacement of the mortar mix cement for the plastering. Mortar mix cement containing 20% fine fly ash and fine rice husk ash can be used to make plastering materials.

This study is meant to help develops better facilities for Tungsten Carbide powder production process. The 10 kg-capacity machine used was able to produce 85 -95.49 percent purity Tungsten carbide powder. When measured, most of the particle sizes and distribution between 0.03-350.00 !lm. which are considered large sized. More than that, those tungsten carbide particles are contaminated by other kinds of metal especially Cobalt binder. We have tried to improve the Tungsten Carbide manufacturing processes by combining more steps including ball milling, drying and screening. After 24-hours ball milling process, the result showed that we were able to produce smaller Tungsten Carbide paliicles sizing from 0.025 to 30.00 ~lm. The obtained particles are also rounder and with &#13;
99.50 percent purity. They are also easier to grade. The Tungsten Carbide manufacturing technology yet needs a further development to eventually produce the desired hard material.

Soybeans are a crop that can be utilized, especially in terms of food rich in protein and fat as the human and animal needs. For using the soybeans must be processed to obtain the desired physical characteristics. The process is mostly a grinding and extraction. However, these two processes are completely different applications.&#13;
This research aims to study and create the soybeans grinder machine become to flour, the quantity of grinding, the variable that affect to the amount of grinding and economic analysis for guiding to investment. The researchers have designed the grinder unit by the coarse grinding and mill grinding unit. For the coarse grinding unit is similar to a disc and in case of grinding mill will be used the roller set. Base on the power train of bolt grinding unit, the electric motor with 2 HP. at 1,450 RPM are used for the experiment. For the grinding mil process, the rough material is feed into grinding mil chamber for reduce the size of material become to the flour.&#13;
The results of the research found that the suitable speed of the coarse grinding and mill grinding unit was 480 and 725 RPM respectively. In case of these relationships, the average quantity of grinding for the coarse grinding and mill grinding unit was 271.8 and 150 kglhr respectively. Furthermore, the results of experiment discover the materials that are not accounted of the coarse grinding for 13.9 percent. For the economic analysis for guiding to investment found that the breakeven point and pay-back period was 110,378 kg and 0.0067 year respectively.

<description>Product development of tungsten carbide scraps
Wongsisa, Saharat; Pokterng, Singkaew; Chomsamut, Kompun; ประสิทธิ์, แพงเพชร
This research is to study the approach for producing the hard materials part by using tungsten carbide powder. The tungsten carbide powder derived from Tungsten scraps recycle processes which are Insert tools scraps, the waste of metal removal process, or derived from usage of machining on machine tools which are the production of metal powder by recovering cemented carbide to tungsten carbide powder and bring it to recycle. The first experiment of this research starts with the production of pure tungsten carbide powder in order to produce the hard metal part how to possibly produce the durable part or hard materials. Preparing tungsten carbide powder which pulverized and mixed with Cobalt co-binder less than 17%, so that molding with the pressure 300 Mpa and sintering at 1430 degree Celsius to the cemented carbide part in Insert tools type, rectangle, SNMG standard 120408 for turning. The result is found that the Insert tools have hardness about 1,385 HV and density 13.45 g/cm3 and then, they are tested to machine specimens in AISI 1045 type. The developed Insert tools can be machining metal removal them as well as the imported Insert tools. It is concluded that the production of Insert tools by recycling of tungsten carbide is qualified as the imported Insert tools. In addition, it is the new developed research in Thailand to be the approach for domestic cutting tools product instead of the imported cutting tools.

Now a day the mostly air condition are use vapor compression refrigeration system in which R-22 refrigerant is used as a working substance. From the results of study, it found that the quantity of water vapor or moisture in the air is condensed with in the fan coil unit while through out the evaporator. The fluid after condense is called condensed water. By this process, the quantity of condensed water is increases when the air condition is used in the long time. To increase the utility, the condensed water is recovered for the heart reduction in the finned-tube condenser.

Nowadays, the Thailand automotive industry widely grows. Brake'pad is one of the automotive productions that role to automotive industry because it is the most critical security parts. Consequently, testing products for quality are extremely requested. However, the equipment and function tests are not enough and are also high cost so it cannot supports to the automotive industry development. In this work, the initiation and design of frictional test were carried out. The testing procedure is referred to The special test jigs for friction measurements JIS K7125[5] and Clutch facings for automobiles JIS D4311[6].A study of the frictional test emphasize on the static friction(l-ls) and kinetic friction(l-lk) in different condition. There are 3 specimens of brake pad supported by the industry company. These specimens were test and compared between the pin on disk's result and the friction testing's result. The two-sided results from the analysis correspond but the pin on disk's friction coefficient is more than the friction testing's friction coefficient by 19.56%. Moreover, the coefficient of friction tends to follow the temperature. Besides, the static friction(l-ls) is likely more than kinetic friction(l-lk) and will be high difference in high pressure condition.
