In a mesh multicomputer performing jobs needs to schedule submeshes according to some processor allocation scheme In order to assign the incoming jobs to a free submesh a task compaction scheme is needed to generate a larger contiguous free region The overhead of com paction depends on the e ciency of the task migration scheme In this paper two simple task migration schemes are rst proposed in ...

In this paper, we propose a heuristic scheduling scheme, named hybrid resource allocation scheme that can reduce the time complexity of scheduling scheme and improve the efficiency of resource utilization while minimizing interference. We first focus on the two-hop relaying scenario, since this scenario has the largest throughput gain, and then explore an extension of the proposed hybrid scheme...

This paper proposes a constructive representation scheme for heterogeneous objects (or FGMs). In particular, this scheme focuses on the construction of complicated heterogeneous objects, guaranteeing desired material continuities at all the interfaces. In order to create various types of heterogeneous primitives, we first describe methods for specifying material composition functions such as ge...

The paper describes the implementation details and validation results for an agglomeration multigrid procedure developed in the context of hybrid, unstructured grid solutions of aerodynamic flows. The governing equations are discretized using an unstructured grid finite volume method, which is capable of handling hybrid unstructured grids. A centered scheme as well as a second order version of ...

For deployed wireless sensor networks, reprogramming sensor nodes through the wireless channel is an important capability. To avoid reprogramming false or viral code images, it is important to make sure that each sensor node can securely receive its code image through the wireless channel. Public key schemes based on elliptic curve cryptography are feasible in wireless sensor networks, yet are ...

This paper focuses on the construction of continuous approximation scheme for the solution of first order initial value problems in ordinary differential equations. We exploit here the elegant properties of the Chebyshev polynomials and derive from the continuous scheme, an implicit hybrid block method through some selected points. The self-starting method was implemented on three test problems...

In this paper, an iterative incremental relay selection (IIRS) scheme is considered for wireless cooperative networks in order to increase the reliability of transmission. Different from the conventional incremental relay selection which incrementally selects a best relay for only one iteration; the IIRS scheme iteratively applies the incremental relaying and relay selection processes. To evalu...

This work proposes a hybrid space vector modulation (HSVM) scheme for multiport converters (MHCs). Moreover, the impact of shifting auxiliary currents from main ones is proposed and investigated in order to enhance converter efficiency. The operational schemes have been implemented three-phase 5 kW MHC prototype. It shown that HSVM can improve efficiency by 0.3% at full load with respect modula...
