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.

Braking Resistor (BR) or Dynamic Brake known for being one of the effective methods to enhance the transient stability of synchronous generators and power systems, following a significant disturbance. By using the Thyristor Controlled Braking Resistor (TCBR) to control the insertion of the braking resistor to enhance the transient stability of the power system. In this paper, two methods for calculating the value of BR, one by using a one per unit value of BR, and the other one is by using a calculating criteria or equation to find the value of BR
Due to its ability to transmit a high rate data stream with maintaining robustness against multipath fading, high spectrum efficiency and efficient implementation, OFDM has been widely used in various communications systems such as DVB, WIFI and WIMAX. It is also considered as a candidate for the air interface of the current and future high speed mobile communications standards such as LTE, LTE advanced. It is also very appropriate for multi-band cognitive radio systems. However, OFDM suffers from some drawbacks. One of them is the Out of Band (OOB) leakage due to high spectral sidelobe which produce interference neighboring bands and then degrade the system performance. Several schemes have been proposed to reduce the OOB emission such as filtering, windowing, precoding etc. in this paper, a hybrid approach based on two Beek’s precoding techniques is proposed and showing a high OOB emission reduction with the same complexity. Simulation results verified the advantages of this scheme as compared with other well-known techniques
