Lighting Control System with Low Rate Network Green Computing System
Lighting Control System with Low Rate Network Green Computing System

This paper presents the development of a low rate and low power consumption low rate wireless network. Low rate wireless networks are cheap and comprised of a small fully autonomous processing communication and remote control devices. The purpose of this study is to develop the system for remote wireless lighting system. They will work with wireless network system (WNS). WNS has been restricted power supply communication distance and low computing power. But they will work with network in vast area send and receive raw data from each network node. It has the ability to cooperatively collect data and retransmit in order to process or alert. The step of the experiment is creating main node and sub node in lighting area and transmission of control data between them with less electrical wiring. When wireless node not receiving or transmitting data the module can be switched into the sleep mode low power consumption mode. We can reduce the use of electrical wiring insulated insulation material or other that related to and include energy too.

Low Rate Wireless Sensor Network Green Computing for Flood Monitoring System

This paper presents the development of a low rate and low power consumption wireless sensor network. Wireless sensor networks are cheap and comprised of a small fully autonomous processing communication and sensing devices. The purpose of this study is to develop the system for monitoring and flood warning. They will work with wireless sensor network (WSN) system. WSN has been restricted power supply communication distance and low computing power. But they will work with network in vast area send and receive raw data from each sensor node. It has the ability to cooperatively collect data and retransmit in order to process or alert. The first step of the experiment is creating main node and sub node in flooding area and finds transmission of data between them. When sensor node is not receiving or transmitting data the module can be switched into the sleep mode low power consumption mode

Econo Power Car
Econo Power Car

Nowadays the fuel energy is consumed more than it was used in the past and most of energy used comes from petroleum which is not reusable. Moreover the crude oil which is raw material to be refined is likely to take place in nature; it usually takes a long time. Therefore this natural resource must be used efficiently to maximize its benefits. Construction of Econo Power Car will be one of many methods to decrease the energy consumption. The objective of research aims to influence parameter effecting to the fuel consumption such as engine system transmission system suspension system and fuel injection system. Furthermore the Econo Power Car is estimated to cooperate with 11th Honda Econo Power. To achieve this the effects of fuel consumption parameters are investigated using experiments. For the suspension system the wheel resistance and the rolling resistance are decreased by wheel angle modification and changing the wheel bearing. Moreover the engine is adjusted by the fuel injector addition. For the economical experiment in the 11th Honda Econo Power the By Part Team (RMUTP Team) has the consumption 843.443 kilometer/liter and within 4th order from 347 teams by the invent higher education of competition and type of 125cc. The winner team has the economize statistics 999.746 kilometer/liter. As a result influence parameters of fuel consumption are wheel resistance and engine system which is good knowledge for the development of the Econo Power Car in the future.

Life Cycle Assessment Study For Two Different Phenol Production Processes
Life Cycle Assessment Study For Two Different Phenol Production Processes

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.

Studying and Product Development of Handicraft from Elephant Dung Paper for Adding Income to Community at Changwat Phra Nakhon Si Ayutthaya
Studying and Product Development of Handicraft from Elephant Dung Paper for Adding Income to Community at Changwat Phra Nakhon Si Ayutthaya

The research aimed to study and develop handicraft products from elephant dung paper for community income generation in Changwat Phra Nakhon Si Ayutthaya and to compare the product satisfaction of the target group for the original style and the new one of elephant dung paper. The target group was composed of 143 tourists from other provinces and 143 local tourists. Both target groups would like to buy handicraft products from elephant dung paper and help generate community income in Changwat Phra Nakhon Si Ayutthaya. Research tool used were questionnaire and data were analyzed by statistical percentage mean and mode. Questionnaire was used for the product attributes satisfaction evaluation of the target group including alternative evaluation process and comparison of product styles evaluation process. Data were analyzed by statistically percentage mean and t-test dependent sample. The results were as follows: 1. The target group chose the third style on 3 designs of handicraft products from elephant dung paper. 2. For the product attribute satisfaction of the target group it was found that the new style of handicraft product was more acceptable than the original one at a significance level of 0.05.
