Crayfish farm is an opportunity for farmers to earn money. Crayfish can farm as pet or food. Information technology can help famer to manage farm efficiently. This research presents the information system for crayfish farm. The crayfish farm system uses wireless sensors for measure temperature and water levels. It can also be feeding automatically through the website. The web application plays as an important role to improve and help manage farm. This application also provides the farm information such as appropriate temperature, date that water need to be change, feed times, and food amount. The system uses Arduino UNO to communicate with sensors, feeder and Raspberry Pi is used to connect to server. The experiment show that the system can work together however this system need improvement to work in real farm.

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.

This research work presents a software tool which is used to generate ruleml rules from a Petri Net structure in the pnml format. A transformation algorithm is presented and illustrated examples are shown. The algorithm employs a depth-first search technique. The generated result is comparable to the result which was presented by other research works.

This paper presents image registration using a combination of Hough transform and phase correlation technique in Fourier domain to estimate rotation and translation parameters. These paramters are used to register input images and create a seamless representation of the registered image. The first step is based on 1D phase correlation which calculates the translation of angle in Hough space, obtained form Hough transform. The rotation parameter obtain from this step is used to de-rotated the input images. The second step provides the translation in x-y axis using 2D phase correlation. Finally, the input images are registered using the estimated translation parameter. The experimental results show the accuracy of the proposed method to detect the translation parameters and find the relevant potential angles of rotation for various image details and sizes. The proposed method is ease to operation, less computation complexity, thus requires less amount of process time due to the high efficiency of fast Fourier transform (FFT).
