Integration of distributed generation (DG) into distribution networks causes some protection challenges, which can be solved by appropriate coordination of directional overcurrent relays. The optimal coordination of directional overcurrent relays is an important task to fulfill the protection requirements of the network. This paper presents an optimal coordination method for directional overcur...

The use of directional antennas in wireless ad hoc networks can significantly improve global performance due to a high spatial channel reuse. Nevertheless, its introduction poses new location dependent problems related to the MAC protocol. In this paper, the Balanced Incomplete Block Design theory has been exploited to develop a new MAC protocol for wireless ad hoc networks using directional ant...

Introduction and aim: In the past few decades, exercise has been promoted with increasing interest for the treatment of back pain. Therefore, the present study aimed to investigate the effect of rehabilitation exercises with medicine beta balls on the directional and general contraction of ankle joint muscles in patients with low back pain during walking. Methods: The present study was a clini...
