The performance of surface damping treatments may vary once the surface is exposed to a wide range of temperatures, because the performance of viscoelastic damping material is highly dependent on operational temperature. In addition, experimental data for dynamic responses of viscoelastic material are inherently random, which makes it difficult to design a robust damping layout. In this paper a...

Due to continuous technology scaling, the interconnect delay and power reduction is becoming one of the most important design challenges. In this paper, we present a novel algorithm for simultaneous multilayer interconnect spacing so that on the one hand the total power of interconnect is reduced and on the other hand, delay constraints are not violated. We first present an optimization problem...

We address the problem of action recognition in unconstrained videos. We propose a novel content driven pooling that leverages space-time context while being robust toward global space-time transformations. Being robust to such transformations is of primary importance in unconstrained videos where the action localizations can drastically shift between frames. Our pooling identifies regions of i...

GONG, ZHENHUAN. Multi-level Data Layout Optimization for Heterogeneous Access Patterns. (Under the direction of Dr. Nagiza F. Samatova.) Recent years have seen an enormous increase in computation power of leadership computing facilities. As a result, huge amounts of data, from terascale to petascale, are being produced by scientific applications running on supercomputers. However, the I/O subsy...

This paper describes the combination of previously-developed component placement and routing algorithms into an integrated computational approach to product layout optimization. Previ ous work introduced simulated annealing-based algorithms for optimal component packing (Szykman and Cagan, 1995), con strained layout (Szykman and Cagan, 1997), and routing (Szyk man and Cagan, 1996). These proble...

This paper describes an innovative analog IC layout generation tool based on evolutionary computation techniques. The designer provides a high level layout description. This template contains placement and routing constrains and is independent from technology. This expert knowledge is used to guide an evolutionary optimization kernel during the automatic generation of the layout for the target ...

Facility Layout Problem (FLP) is logic based combinatorial optimization problem. It is a meta-heuristic solution approach that gained significant attention to obtained optimal facility layout. This paper examines the convergence analysis by changing the crossover and mutation probability in an optimal facility layout. This algorithm is based on appropriate techniques that include multipoint swa...

this article presents the application of two algorithms: heuristic big bang-big crunch (hbb-bc) and a heuristic particle swarm ant colony optimization (hpsaco) to discrete optimization of reinforced concrete planar frames subject to combinations of gravity and lateral loads based on aci 318-08 code. the objective function is the total cost of the frame which includes the cost of concrete, formw...
