Most existing methods for scheduling are based on centralized or hierarchical decision making using monolithic models. In this study, we investigate a new method based on a distributed and locally autonomous decision structure using the notion of combinatorial auction. In combinatorial auction the bidders demand a combination of dependent objects with a(More)
Motion compensation (MC) is one of the most important technologies capable of removing the temporal redundancy and widely adopted by the main video standards. From the older MPEG-2 to the latest H.264 and the Chinese AVS, many efficient coding tools have been introduced into MC, such as new motion vector prediction, bi-directional matching, quarter(More)
In this paper, we introduce our Message Passing Interface (MPI) based Object-Oriented parallel discrete event simulation framework. The framework extends the capabilities of the OMNeT++ simulation system. In conjunction with this project, our research efforts also include the development of synchronization methods suitable for architectural properties of(More)
A novel perceptually lossless coder is presented for the compression of medical images. Built on the JPEG 2000 coding framework, the heart of the proposed coder is a visual pruning function, embedded with an advanced human vision model to identify and to remove visually insignificant/irrelevant information. The proposed coder offers the advantages of(More)
In this paper, we investigate three iDDT-based test methodologies, Double Threshold iDDT, Delta iDDT, and Delayed iDDT, and we compare their effectiveness in the detection of defects in very deep sub-micron random logic circuits. The target defects are resistive opens and resistive bridges. We present preliminary simulation results of 49 defects to study(More)
We know very little about the use of computers by children under the age of three. While few children in that age range used computers before the advent of smartphones and tablets, these devices have made computers much more accessible to infants and toddlers. In this paper, we provide a window into how these children are using tablets through an analysis(More)
We study incentive issues that arise in semiconductor capacity planning and allocation. Motivated by our experience at a major U.S. semiconductor manufacturer, we model the capacity-allocation problem in a game-theoretic setting as follows: each product manager (PM) is responsible for a certain product line, while privately owning demand information through(More)
