For modern VLSI circuits the well known Moore's law is used to generate road maps describing the expectations for the next generations of integrated circuits in which downsizing is accompanied by increasing circuit complexity and increased die size. This will greatly affects clock speed, interconnects and wire length as illustrated figure 1 [1]. Modern VLSI chips are expected to operate with a ...

We investigate a version of the time-dependent Ginzburg-Landau system that models a thin superconducting wire subjected to an applied voltage. Using a mixture of rigorous analysis, formal asymptotics and numerics, we analyze the behavior of solutions as the physical parameters of wire length, voltage and temperature are varied. Stable periodic solutions are shown to exist exhibiting phase slip ...

This computational neuroanatomy study evaluates how well some formalisms derived from combinatorial network optimization theory fit as models for brain structure. At multiple hierarchical levels--brain, ganglion, individual cell--physical placement of neural components appears consistent with a single, simple goal: minimize cost of connections among the components. The most dramatic instance of...

An optimal partition between on-chip and on-board interconnects is proposed, which achieves the highest possible global clock frequency as well as high wiring density. A general model is developed for adequate number and size of repeaters and the impact of this model on optimal partition of interconnects is also studied. Using on-board wires the global clock frequency of a projected system-on-a...

T.C. Fan*, F.Y. Lin, C.S. Hwang, Ian C. Hsu Synchrotron Radiation Research Center, Hsinchu, Taiwan National Tsing Hua University, Hsinchu, Taiwan Abstract Several laboratories have used the pulsed wire method for magnetic field measurement. The acoustic wave distortion of the wire was observed. The limitations of this method were discussed. A pulsed wire system is under test in SRRC on an undul...

Estimating the costs of blasting operations is an important parameter in open-pit mining. Blasting and rock fragmentation depend on two groups of variables. The first group consists of mass properties, which are uncontrollable, and the second one is the drill-and-blast design parameters, which can be controlled and optimized. The design parameters include burden, spacing, hole length, hole diam...

In this paper we address the problem of automatic arrangement of cameras in a 3D system to enhance the performance of depth acquisition procedure. Lacking ground truth or a priori information, a measure of uncertainty is required to assess the quality of reconstruction. The mathematical model of iso-disparity surfaces provides an efficient way to estimate the depth estimation uncertainty which ...

The minimum linear arrangement problem (MinLA) was first stated by Harper in [5]. His aim was to design error-correcting codes with minimal average absolute errors on certain classes of graphs. Latter, in the 1970’s it was used as an abstract model of the placement phase in VLSI layout, where nodes of the graph represented modules and edges represented interconnections. In this case, the cost o...

Excessive on-chip wire length and fast increasing fabrication cost have been the main factors impairing the effectiveness of monolithic System-on-Chip. This paper investigates a die stacking based system integration strategy (2.5D system integration) to address these problems. The new scheme is design-tools-enabled rather than technologydriven. We developed a layout design framework, which is a...

OBJECTIVE The objective was to present a straightforward, step-by-step reproducible technique for placement of a guide-wire into any type of urethral catheter, thereby offering a means of access similar to that of a council-tip in a situation that may require a different type of catheter guided over a wire. MATERIALS AND METHODS Using a shielded intravenous catheter inserted into the eyelet o...
