Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

The major problem facing the power industry today is reliability of power supply. The task of power system protection is to provide adequate protection for the network. However, faults do occur in a power system and there is need to isolate the faulty equipment or section from the healthy part of the system faster. This paper provides the design and implementation of the protection of a disturbed electric network using a solid state relays for enhancement of power system protection. The design and implementation was done in four stages; power supply unit, voltage sensing unit, current sensing unit, and the switching. The result shows that the relay with the help of opto-coupler, constantly monitor the parameter, overload voltage and overcurrent that are to be controlled and if it exceeds the percentage range set by the operational amplifiers then it sends a signal to the switching circuit to break the connection and isolate the faulty part at a minimal delay time. The implementation of relay thus, enables better time response for protection
The purpose of the research is to produce the item bank to measure polytechnics students’ performance in Mathematics algebra topic. Computerized Adaptive Test, an adaptive mode of testing that has the features to measure the performance of test takers based on their ability level. Computerized Adaptive Test has the ability to precisely target test item difficulty to estimate test-taker ability. However, computerized test can only be realized if item bank that contains sets of questions with different difficulty levels is developed. In order to produce the item bank, this study uses a combination of linking and equating of 36 sets of test related to Mathematics Algebra. All 36 sets of test are administered to a sample of 1,464 students from 4 polytechnics in northern Peninsular Malaysia. The findings of this research show that the item banks are credible and reliable. Using Rasch model and item-response-theory, this research proves that the items can be used for item bank designed for Computerized Adaptive Testing
