In this paper, we design and analyze a multiwavelength network with dynamic channel sharing. Traffic in the network is categorized into a real-time and a nonreal-time classes. The network blocking performance with and without channel sharing is analyzed and compared. Results show that the proposed dynamic channel sharing protocol can substantially improve the network performance without increas...

As a result of the performance measurement revolution many organisations have numerous measures of performance but often with significant weaknesses in the way that these measures are identified, integrated, communicated and acted upon. First generation performance measurement frameworks have partly contributed to this as none of the approaches addresses the full range of criteria important for...

Personal comfort systems (PCS) that warm or cool local body parts promise individual thermal comfort, energy saving and (metabolic) health in non-neutral environments. However, research on work performance while using a PCS is scarce. We previously tested warms the extremities cools head reported improved during ramp of 17-23˚C but did not at stable temperature 25˚C. In current study, its effec...

Contention resolution plays an important role in designing medium access control protocols. Owing to technical constraints of wireless sensor networks, the task of efficiently resolving contention poses severeal challenges. In clustered wireless sensor networks, many-to-one communication is the dominant pattern, which is also applicable to the star topology. This paper surveys the state-of-the-...

Motivated by applications of social network analysis and of Web search clustering engines, we describe an algorithm and a system for the display and the visual analysis of two graphs G1 and G2 such that each Gi is defined on a different data set with its own primary relationships and there are secondary relationships between the vertices of G1 and those of G2. Our main goal is to compute a draw...
