We propose a grid based subtree-subcube assignment strategy for using nested dissection in solving PDE problems on hypercubes. A complexity analysis is given for both our approach and the standard subtree-subcube assignment. The new assignment reduces communication cost by a factor of 0 (logp) in start ups and a factor of about two in traffic volume. This grid based assignment strategy achieves...

In recent years, there has been considerable interest within the tracking community in an approach to data association based on the m-best two-dimensional (2-D) assignment algorithm. Much of the interest has been spurred by its ability to provide various efficient data association solutions, including joint probabilistic data association (JPDA) and multiple hypothesis tracking (MHT). The focus ...

Abstract: A control architecture for resource allocation in satellite networks is proposed, along with the specification of performance indexes and control strategies. The latter, besides being based on information on traffic statistics and network status, rely upon some knowledge of the fading conditions over the satellite network channels. The resource allocation problem consists of the assig...

There has been growing interest in broadband satellite networks lately. The unique characteristics of satellites such as long propagation delay, limited bandwidth to be shared among many users, and power limitations necessitate the use of appropriate medium access control (MAC) schemes for bandwidth assignment, particularly in applications with bursty traffic. This paper presents a study of MAC...

The traditional trip based approach to transportation modeling has been employed for the past thirty years. However, due to the limitations of traditional planning for short-term policy analysis, researchers have explored alternative paradigms for incorporating more behavioral realism in planning methodologies. On the demand side, activity-based approaches have evolved as an alternative to trad...
