We propose a new system for image recorder server from IP camera. The system consists of 2 parts, Server and viewer. Server is software running on PC with ability to capture image from IP camera and save to disk like an image server. The second part is the viewer. A user be able to monitor and view the saved image on the server via a web-based application from everywhere with password protection. Live and history image can be show to user to check the status of area or investigate the history event. Further more. The server can connect to IP camera to collect image or connect a web cam directly to the server for cost reduction. Finally, the user can view the image by using browser on the PC or Windows mobile phone.

Home appliances-controlled platform with HomeKit application is a platform that allows users to control general appliances via HomeKit, which is an application from Apple on any device running iOS10 or later. The platform is the communication medium between application and appliances. The appliances do not need to be manufactured by Apple since they are expensive and have to put an effort in case the customer want to buy it. The platform is capable of receiving and transferring data to a HomeKit application for data processing, then transmits signal back to control the operation of the appliances. Within the platform, there is a section that acts as a communication server for the HomeKit application which is like a direct Apple server. In addition to receiving and sending data from the HomeKit application, the platform also has an automatic control that is controlled by the reading sensor contained in each platform comparing the threshold values, user defined. Each platform has different sensors based on their operations and can control only one type of appliance because each type of control uses different signal, the control must be unique, matching the type of appliances and the form of command in different manufacturers.

The growth of economic influences city authorities to plan and build infrastructure. The growth prediction mostly uses modern mathematical models. The accuracy of the model is highly depended on reliable parameters. Two crucial parameters for most models are traffic capacity and average travel speed along road networks and obtained from an origin-destination (OD) estimation. Thus, an OD estimation is necessary to obtain reliable parameters for the predictive models. Traditionally, the OD estimation is performed by human observation; however, an automatic license plate recognition and matching algorithm show potential of obtaining such data. Additionally, the observation is able to perform long term observation which is impractical for human. Therefore, this paper reports an empirical experiment on OD estimation using automatic license plate matching along with a real-world human observation survey in Mukdahan province. The results from both types of surveys are reported and compared. The different results between the both raises an opportunity for researching an optimal method of OD estimation in Thailand.

A dark soliton pulse beam that has potential applications in the probing and transport of atoms or molecules as an optical tweezers is demonstrated. The trap pulse beam is formed in the gap between a BP signal at 1500.00 nm and Stokes signal at 1500.09 nm, which have peak powers of -12 dBm. The generated beam is seen to be stable with no fluctuations over a test period of 10 minutes, which is important to ensure that the transported atom / molecule is not lost in the link media. ©2010 IEEE.

This research proposes the smart way to solve the common problem of the conventional door-locking system. The important problems of the ordinary door-locking systems are key lost, forgetting to lock the system and cannot check the lock status from remote. To solve these problems, we proposed a method to lock-unlock the system which utilizes the web application and passcode alongside the usual method of using the ordinary keys. The proposed system can remotely lock, remotely unlock, remotely check door state, remotely check door locking state, send the email to the owner in case of someone knocking on the door and generate the temporary passcode to use in specific date and time.

We propose a new system for wireless traffic light controller, it makes a traffic policeman easily and effective control a roadjunction with a wireless remote control. The system has two modes, Manual and Automatic. Manual mode provide the control oftraffic light to change manually by the traffic policeman, by just press the button related to the direction of the street to make agreen light signal. The remote will respond by checking the bearing of the pressed button on the remote using Hall effects sensorregarding to the position and direction of the remote. Then send the control signal to the traffic light controller board. Inautomatic mode, the traffic light controller board will change the light sequence according to the preset patterns and time delay,the traffic policeman be able to change the pattern at any time using the remote. The propose system help the policeman tocontrol the junction by himself and be able to change conditions of the traffic flow dynamically.

The calibration system was developed for golf shaft fitting to the club or blade. The system provided the best line and angle of golf shaft to fit into the club slot. This yielded the best controlling for the impact point between the club and the golf ball, including obtained the minimal swaying of golf shaft after the club hit to the ball. The proposed system was consisted of two components: the hardest line tuning and the best line calibration tool. The hardest line tuning was applied to search for the line that indicated the most strongest of the shaft, which contributed the minimal bend within the given certain forced pressure. The best line calibration tool was employed to determine the best angle for fitting the shaft to the golf club which reflected the minimal swaying while hitting to the ball. In this manner, the golfers could control the desired range and direction of the ball. © 2010 Published by Elsevier Ltd.

We propose a novel system for generating multiplexed dark-soliton pulses using multiple light sources via an optical multiplexer, whereby dark solitons with different center wavelengths can be generated. The multiplexed signals can be transmitted into the communication link and filtered by using an optical add-drop filter. By using suitable simulation parameters, we have shown that dark solitons with different center wavelengths can in fact be obtained. In application, the communication capacity can be increased by using the multiplexed dark solitons; moreover, the transmission signals can be secured by utilizing the behavior of dark solitons. A free spectrum range (FSR) 2.5 nm and an amplified power of 30 W of dark solitons with wavelength 1.60 μm can be achieved. Channel spacing of the communication signals within a wavelength router can be provided by using a suitable FSR, which can be managed by using crosstalk effect analysis. © 2010 Society of Photo-Optical Instrumentation.

We present the fascinating results of dark soliton pulse array generation using the multilight sources via an optical multiplexer. The dark soliton array with different center wavelengths can be generated. The experimental setup was operated by using the brillouin-enhanced fiber laser scheme, whereas the experimental results of the dark soliton array are generated and achieved. In application, the dark soliton array can be used to form the molecules/atom trapping array, which can be used to form the molecules/atoms memory array for molecular computer and communication. Moreover, the transmission molecules/atoms can be secured by using the dark-bright soliton conversion behaviors. Results obtained have shown that the free spectrum range and the amplified power of 2.1 nm and 20 W of the bright soliton after dark-bright soliton conversion with wavelength center at 1.50 μm can be achieved, respectively. © 2010 Wiley Periodicals, Inc.
