In this paper, we study wire width planning for interconnect performance optimization in an interconnect-centric design flow. We first propose some simplified, yet near-optimal wire sizing schemes, using only one or two discrete wire widths. Our sensitivity study on wire sizing optimization further suggests that there exists a small set of “globally” optimal wire widths for a range of interconn...

Placement of multiple dies on an MCM substrate is a difficult combinatorial task in which multiple criteria need to be considered simultaneously to obtain a true multi-objective optimization. Our design methodologies consider multi-objective component placement based on thermal reliability, routing length and chip area criteria for multi-chip module. The purpose of the multi-objective optimizat...

The live-wire approach is a well-known algorithm based on a graph search to locate boundaries for image segmentation. We will extend the original cost function, which is solely based on finding strong edges, so that the approach can take a large variety of boundaries into account. The cost function adapts to the local characteristics of a boundary by analyzing a user-defined sample using a cont...

An experimental investigation was carried out to determine heat transfer coefficients for natural convection from a heated horizontal wire. The heating is provided by electrical current, and the temperature of the wire is determined from the measurement of its resistance. The experiments are performed in three different convective environments: air, water, and oil. Prandtl number ranged between...

We study transport properties of a strongly correlated monoatomic chain coupled to metallic leads. Our system is described by tight binding Hubbard-like model in the limit of strong on-site electron-electron interactions in the wire. The equation of motion technique in the slave boson representation has been applied to obtain analytical and numerical results. Calculated linear conductance of th...

Due to the large surface to volume ratio in nanowires, small changes in surface condition result in large changes in current–voltage characteristics. As a consequence, the overlap of the end-wire contact with the oxide-covered surface along the length of the nanowire can have a significant effect on the current–voltage characteristics of the wire. We present TCAD studies of this effect. One of ...

abstract level of groundwater is decreased which is mainly because, withdrawal of groundwater is increased, because of lack of right management. economics of rural based farming and farming is dependent of water so decreasing of groundwater effects social welfare. in this study decrease of welfare measure by reason of reduction of groundwater level considered. this study investigated the impact...

In this paper we consider an imperfect production system which produces good and defective items and assume that defective items can be reworked. Due to the nature of rework process we do not restrict the rework rate to be equal to normal production rate or constant and assume that it is a random variable with an arbitrary distribution function. We also assume as it is true in most real world s...
