Cellular Manufacturing (CM) has been emerged as a strong approach for improving operations in batch and job shop environments. In cellular manufacturing, Cell formation, static layouts, dynamic layouts are the prime areas for achieving the optimal cellular layout for any problems. In this paper it is decided to review the recent research work in this particular area and to project the effective...

A multi-phase comprehensive method for the design of hybrid cellular manufacturing (HCM) system is presented in this paper. The initial phase aims at categorizing parts to be produced on the cellular or the functional layout facilities of the system. Second and third phases show a mathematical approach with two inter-related models, where the first is to determine the formation of cells and the...

FPGA is a 2D array of configurable logic blocks. Packing is to pack logic elements into device specific configurable logic blocks for subsequent placement. The traditional fixed delay model of inter and intra cluster delays used in packing does not represent post-placement delays and often leads to sub-optimal solutions. This paper presents a new layout driven packing algorithm, named LDPack, b...

The speed of serial interface through a backplane channel suffers severe ISI (Inter Symbol Interference) caused by the limited bandwidth of the channel. In order to overcome the bandwidth limit, a pulse shaping circuit or an adaptive equalizer is used. This paper presents the comparison between two approaches. Prototype chip is designed for 10Gbps serial data communication through a 34-inch tra...

We propose to exploit reaction-diffusion (RD) patterns as part of the wireless sensor network (S-Net) high-level structure building toolkit; e.g., to support leader selection or to provide pathways through the network. In particular, we study the formation of RD spot and stripe patterns in S-Nets for which no coördinate frame exists; i.e., the nets have only topological connectivity determined ...

Spacecraft autonomy is becoming an increasingly important technology. Yet the very nature of autonomy − on-board decision making and largely unattended operation − makes it important that such systems be thoroughly tested and validated. We are developing software visualization tools to assist in the validation process. The tools, which are designed to facilitate human problem solving, combine g...

The MIT approach to 3-D VLSI integration is based on low-temperature Cu-Cu wafer bonding. Device wafers are bonded in a face-to-back manner, with short vertical vias and Cu-Cu pads as the inter-wafer throughway. In our scheme, there are several reliability criteria, which include: a) Structural integrity of the Cu-Cu bond, b) CuCu contact electrical characteristics, and c) Process flow efficien...

| The inter-wire spacing in a VLSI chip becomes closer as the VLSI fabrication technology rapidly evolves. Accordingly, it becomes important to consider crosstalk caused by the coupling capacitance between adjacent wires in the layout design for the fast and safe VLSI circuits. The upper bounds of the allowable crosstalk for nets, called cross-talk constraints, are usually given in the design s...

The inter-wire spacing in a VLSI chip becomes closer as the VLSI fabrication technology rapidly evolves. Accordingly, it becomes important to minimize crosstalk caused by the coupling capacitance between adjacent wires in the layout design for the fast and safe VLSI circuits. We present a simulated annealing approach based on segment rearrangement to crosstalk minimization in an initially gridd...

Abstract: This paper presents a simplified, introductory view of how visual atThis paper presents a simplified, introductory view of how visual attention may contribute to and integrate within the broader framework of visual scene understanding. Several key components are identified which cooperate with attention during the analysis of complex dynamic visual inputs, namely rapid computation of ...
