Private design project for tourists around the Rattanakosin Island researchers have been studying the various documents and research. It led to the design process. Researchers have taken the concept in the design with emphasis on the beauty. To promote tourism. Energy savings. And consistent with the environment around Rattanakosin Island. As well as the comfort of the driver or the traffic on my sidewalk. The development of the bike park to park in the inclination to narrow the width of the base. Beam for more. Handle the bike is in the 140-150 cm in the eyes of the park. I do not have a roof level (that is 2 meters) at the car park at the wheel along with the pressure curve. Hands are placed in 140 cm and the car just to hang on the beam with a height of 170 cm but the car is not perpendicular to the ground because the balance of the car at hand. The car is tilted about 60 degrees the width of 160 cm from the principles already mentioned. We made sure the bike is a beauty and a functional purpose. Analyzing data from the query as follows. - Status (those who use bicycles in the city and tourism) are male than female 68 percent are between 21-30 years of age are 43 percent in undergraduate education is 61 percent. 5000-10000 baht in revenue and a 38 percent majority of the employees 31percent.

This research report of the Aluminum Can Recycle Machine Project is contrived the experiments at Rajamangala University of Technology Phra Nakhon by the hydraulic pressure. Nowadays the cans make by luminum material very useful in several liquid packaging industries. When people consumed the liquid inside the cans then the cans are worthless. But the cans can be recycling from the waste material. Although we have to reduce the waste materials to follow our world as improvement. From the reasons that we mentioned we decided to start the Aluminum Can Recycle Machine research project to keep him or her eager to put the cans to the machine for consumer then encourage them by giving something back such as a candy or a rubber etc. The system working by a PLC it controls the hydraulic pressure receives the sensor signals and displays status via the 7-segment panel. The machine accepts the standard beer can and the soda can for 10 cans a time in a slot when consumer put the cans into the can receiver block the machine gives a candy back to a consumer. After a receiver-block has the 40 cans inside the machine pressing the cans at once then releasing it to collector block.

This paper presents compare results performance between two conventional controllers for bicycle robot. The bicycle speed control system was a highly nonlinear model multivariable and absolutely unstable. It has used for testing various design control techniques for low power. The objectives of this paper had to developed speed control which derived the mechanic model and experiment. Controllers are Proportional-Integral-Derivatives (PID) and on-off dynamic control. The dynamic system which also includes not stable friction effects the linear zed system model is used as a basis for the design to apply to speed. Computer simulation and experiment have been done controller are capable to control output speed wheel control system successfully. The results show PID controller better then on-off dynamic controller.

Phenol is an important raw material in many branches of industry (petrochemical pharmaceutical plastic and pesticidal chemical industry ). This research study on phenol production processes by using two different phenol production processes which are cumene oxidation (the Hock process) and toluene oxidation (the Dow process). In order to study in environmental impacts Life Cycle Assessment (LCA) is applied to evaluate environmental impacts of phenol production processes. Environmental impacts are evaluated according to cradle-to-gate approach by using SimaPro 7.1 software for Life Cycle Assessment . Approach by IMPACT 2002+ . The result shows that cumene process is more environmentally favorable than toluene process.

Activated carbon also called activated charcoal or activated coal is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for adsorption or chemical reactions. In this research studies environmental impacts of activated carbon production processes which produced from two types of agricultural by-products namely : coconut shells and palm-oil shells . SimaPro software is applied to evaluate the environmental impacts of both processes. The results have shown that the environmental impacts for the process using coconut shells as raw material is higher than that using palm –oil shells as raw material.
