This diagnostic connection allows an administrator to access SQL Server to execute diagnostic queries and troubleshoot problems even when SQL Server is not responding to standard connection requests (i.e. SQL SERVER Crashes). This paper published by Illinois Institute of Technology talks explains the Tips on Microsoft SQL Server 2005 Admin: Microsoft SQL Server 2005 Administration. This paper has some of the rich SQL Server 2005 Administration features explored with explanation on how to use them.
Wireless network topology control has drawn considerable attentions recently. However, priori arts assumed that the wireless ad hoc networks are modeled by Unit Disk Graphs (UDG), i.e., two mobile hosts can communicate as long as their Euclidean distance is no more than a threshold. However, practically, the networks are never so perfect as unit disk graphs: the transmission ranges may vary due to various reasons such as the device differences, the network control necessity, and the perturbation even the transmission radii are set as the same. This paper proposes the first distributed mechanism to build a sparse power efficient network topology for non-uniform ad hoc wireless networks.
