Collaborative identity in project alliances: improving collaboration through collaborative identity formation

As a result of the high failure costs and many project delays in the construction industry, collaborative contracts emerged in an attempt to improve project performance. The project alliance was one of them. This integrative way of working requires a focus on the human aspects, because people from different organisational cultures are brought...

Distributed beam forming with phase-only control for green cognitive radio networks

Cognitive radio (CR) is an intelligent radio system and is able to share the spectrum with licensed users (LU). By adopting adaptive beam forming techniques, CR can reuse the spectrum with LU via directing main beams towards CR users while displaying nulls towards LU. In this article, we present a new distributed beam forming (DB) technique, and...

Efficient radio transmission with adaptive and distributed beamforming for intelligent WiMAX

In this paper, we introduce Adaptive Beamforming (AB) and Distributed Beamforming (DB) as two efficient techniques for IntelligentWiMAX (I-WiMAX). I-WiMAX is a new maritime communication system, consisting of Smart Radio (SR) principles and mobile WiMAX based on the IEEE 802.16e standard. Adopting AB, the same spectrum can accommodate more users...
