Using Green's function, we confirm that the method invented by Rayleigh can be generalized to deal with thermal property of these systems. A technique for calculating effective thermal conductivities of these systems is proposed. As an example, we consider a system with square symmetry, and a neat formula for effective thermal conductivity is derived. We show that the method also includes the proof of Keller theorem.展开更多

The VLSI layouts of most previous studies are based on the classical H-tree layout, resulting in low area utilization and likely an unnecessarily high manufacturing cost simply due to the waste of a significaot portion of silicon area. In this paper, we present an area-efficient approach to the reconfigurable binary tree architecture. Area utilization and interconnection complexity of our design compare favorably with the other known approaches. In the reliability analysis, we take ioto arcount the faCt that accepted chips (after fabrication) are with dmereot degrees of redundancy initially, so as to obtain results which better reflect real situations.展开更多
