This research presents the development of a low rate wireless sensor. 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.

This research 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.

The Purpose of this research is to study the Usage and Satisfaction towards Internet of Students at Rajamangala University of Technology Pra Nakorn. This study is a survey research. The instruments used in this research are questionnaire. The sample groups in this research were Rajamangala University of Technology Phra Nakhon 400 persons. The statistics by means of Arithmetic means percentage value t-test and Oneway ANOVA Analysis. The results of the study are as follow: 1.The students with different sex have no significant. 2.The students with different ages have no significant. 3.The students with different academic levels have no significant. 4.The students with different s~mesters have no significant. 5.The students with different faculty have no significant. 6.The students with different type of accommodation have no significant. 7.The students with different type of income have no significant. 8.The students with different expense have no significant.

This OmniSwitch 7700/7800/8800 Network Configuration Guide describes how to set up and monitor software features that will allow your switch to operate in a live network environment. The software features described in this manual are shipped standard with your OmniSwitch 7700 7800 or 8800. These features are used when setting up your OmniSwitch in a network of switches and routers.

The purposes of this research are 1) to create computer multimedia through the Internet teaching tool for lighting for broadcasting course (undergraduate level) 2) to develop and to find out quality the create computer multimedia through the Internet teaching tool for lighting for broadcasting course (undergraduate level) and to achieve efficiency according to a set of 90/90 criterion. The samples for this study were 48 second year students of Bachelor of Technology Program in Radio and Television Broadcasting Technology studying this course in the first semester of 2011 academic year at Rajamangala University of Technology Phra Nakhon. The samples were selected by simple random sampling. The research tools used are the computer multimedia through the Internet an achievement test evaluation forms for quality assessment. Statistics used for analyzing the data were percentage and mean. The results of the study revealed that the computer multimedia instruction through the Internet was ranked as a very good level by content experts and as a very good level by educational technology experts and had its efficiency of 94.80/96.60 it was higher than criteria set 90/90
