multicast routing is one of the most important services in multi radio multi channel (mrmc) wireless mesh networks (wmn). multicast routing performance in wmns could be improved by choosing the best routes and the routes that have minimum interference to reach multicast receivers. in this paper we want to address the multicast routing problem for a given channel assignment in wmns. the channels...
Massive uniform nested loops are broadly used in scientiic and DSP applications. Due to the large amount of data handled by such applications, the optimization of data accesses by fully utilizing the local memory and minimizing communication overhead is important in order to improve the overall system performance. Most of the traditional partition strategies do not consider the eeect of data ac...
Multidimensional databases have been playing a significant role in the database field. However, some cases may need a more flexible model than the rigid structure of a data cube where all cells in each dimension resolultion combination must be filled. Generally, a data cube may be viewed as a multiple partition over a population. We propose a two-level formalism for modeling multiple partitions...
We propose a multiresolution Gaussian process to capture long-range, non-Markovian dependencies while allowing for abrupt changes. The multiresolution GP hierarchically couples a collection of smooth GPs, each defined over an element of a random nested partition. Long-range dependencies are captured by the top-level GP while the partition points define the abrupt changes. Due to the inherent co...
Abstract A real symmetric matrix is copositive if $$x^\top Ax\ge 0$$ x ⊤ A ≥ 0 for all $$x\ge . As and only it on the standard simplex, algorithms to determine copositivity, such as those in Spons...
Previous work on functional joins was constrained in two ways: (1) all approaches we know assume references being implemented as physical object identifiers (OIDs) and (2) most approaches are, in addition, limited to single-valued reference attributes. Both are severe limitations since most object-relational and all object-oriented database systems do support nested reference sets and many obje...
Abstract- Tracking a target which is sensed by a collection of randomly deployed, limited-capacity, and short-ranged sensors is a tricky problem and, yet applicable to the empirical world. In this paper, this challenge has been addressed a by introducing a nested algorithm to track a maneuvering target entering the sensor field. In the proposed nested algorithm, different modules are to fulfill...
Although eecient uniication algorithms exist for logic database queries for at relations , no eecient uniication algorithm has been proposed for logic database queries for nested relations. As a result, the required time to process logic database queries for nested relations is often less than ideal. To overcome this shortcoming, we propose here a linear time uniication algorithm for a large cl...
