Car theft warning system via the mobile phone service by SMS
In this research the concept of a burglar alarm system is currently used mainly blaring alarm when an intruder but with todays busy society the voice of alarm no interest or some car owners might not hear the sound of the signal due to the car park. The thieves take the opportunity to have success car theft with mobile messaging technology that costs less and is very active in the daily life of common people. Therefore the development of vehicle theft alarm system with short messages via mobile phone to improve the performance of the car alarm system can send a short message to the mobile phone owner immediately. The motion sensor device that is installed in the vehicle to detect theft or intrusion cars. Invasive test methods such as smashed glass opening the car door. Reaching into the car or inside the front of the car. The system can detect all. It sends messages to the phones owner and the owner of the car did not turn off the car or by calling into the system and then hang up. The system sends a message to every one minute
Study of a small vacuum coating system for thermal evaporation
In this research we studied and fabricated a small vacuum coating system which is suitable for small pieces of the samples. It can help us to save in both cost and time for coating materials in each run. The home-built system consists of (1) a two-stage rotary pump used as a roughing and backing pump for a vacuum chamber and (2) a diffusion pump. The ultimate pressure of this diffusion pump is about 10-7 torr. From the result of testing the fabricated vacuum system it is found that the chamber pressure under the atmosphere can get down to 2.2 x 10-2 torr in 6 minutes by the rotary pump. The pressure inside the chamber is continuously lower to achieve 4.5 x 10-5torr in 30 minutes by the diffusion pump. Moreover we did further testing the system by coating pure aluminum (99.999%) on a Si (100) substrate using a resistive heater source made of tungsten with applied voltage and current of about 2.19 V and 110 A respectively. The aluminum surface has been investigated by SEM and AFM.
Management information systems for the building
This paper presents an Information system for the management of the building and location. By the building Class room Timetable Schedule Photos building and Photo structure for building put on to collect the necessary information and can be easy accessed through the presentation with a web browser making agencies can be useful to use it is the And can be checked The system can allocate a code to bring the teaching of information management department is properly registered. And data to help executives make decisions about planning and building for the future. The assessment of the system’s quality was performed by 6 experts which discovered the system had a good level of satisfaction. The result of the evaluation from experts found mean at 4.00 with standard deviation at 0.36 In conclusion this system achieved all goals and gained a high level of satisfaction from all user
Development Information System to support activities of Nang Loeng Community, Bangkok
The objectives of this research are to analysis design and develop the Information System to support activities of Nang Loeng Community Bangkok. Also to install test and evaluate the system. To develop the System Development Life Cycle (SDLC) method is used. To develop and implement PHP script language and MySQL database management system are used. And the system is installed on the Internet Server. To evaluate the satisfaction the 2 groups are the samples the first is the group of 19 operation users and the second is the groups of 30 general users. Convenience sampling is used for sampling method. Gathered and analyzed the data by statistical processing program for Windows software. The result of research show that the satisfaction of the first group (19 operation users) about input screen a data entry is in a good level (x=4.00). About working process and reporting of the system is in a good level (x=4.15) the satisfaction of the group is a good level (x=4.08) The satisfaction of the group (43 general users) the results appear in the same level to the satisfaction of the first group in every case (x=4.21). So the research results can be concluded that all samples are highly satisfied with this information system. And this system can be installed in real working and suit the user requirement.
Development of monitoring system for mobile weather station
The objective of this research was to develop a high performance monitoring software for extended database of mobile weather station by using embedded computer. The monitoring system could measure and record temperature relative humidity wind speed and direction rainfall solar radiation and UV index. The software could convert these parameters and sent them from mobile unit to base unit within 60meters distance via 868.0MHz of radio frequency. The embedded computer was used as for database and host of the monitoring software. This software was developed by using LabVIEW with large MySQL database. The software could work perfectly. That is it could monitor and display any parameter in real time in both graphic and numerical data. It could also produce a report in correct format of research information. The Monitor system could work with the embedded computer. The mobile weather station could be used in remote areas with photovoltaic energy system and storage battery specially designed for them.
