With the dramatic increase in mask costs, multi-project wafers have became an attractive choice for low-volume chip fabrication. By using the same set of masks to fabricate a number of different chips, the mask-set cost is amortized among different chip providers, leading to significant cost reduction especially for chip prototyping. In this paper we present a new algorithm for reticle floorpla...

The goal of retargetable machine-code decompilation is to analyze and reversely translate platform-dependent executable files into a high level language (HLL) representation. This process can be used for many different purposes, such as legacy code reengineering, malware analysis, etc. Retargetable decompilation is a complex task that must deal with a lot of different platform-specific features...

We describe the successful application of a new method to estimate permeability and permeability anisotropy from transient measurements of pressure acquired with a wireline straddle-packer formation tester. Unlike standard algorithms used for the interpretation of formation-tester measurements, the method developed in this paper incorporates the physics of two-phase immiscible flow as well as t...

Inflation-adjusted farm prices and farm-wholesale marketing margins for beef and pork have declined over several decades. For example, from 1970 to 1998, real slaughter steer and hog prices declined by 50% and 66%, respectively, while real beef and pork farm-wholesale (FW) marketing margins declined by 57% and 65%, respectively (Figures 1 and 2). These changes have been attributed to declining ...

Several recent investigations indicate that tube-wave amplitude attenuation in acoustic full-waveform logs is correlated with permeability in fractured rocks. However, there are significant differences between predictions based on theoretical models for tubewave propagation and experimental waveform amplitude data. This investigation reviews the results of existing theoretical models for tube-w...

We consider the problem of finding all enclosing rectangles of minimum area that can contain a given set of rectangles without overlap. Our rectangle packer chooses the xcoordinates of all the rectangles before any of the y-coordinates. We then transform the problem into a perfect-packing problem with no empty space by adding additional rectangles. To determine the y-coordinates, we branch on t...

The paper is a reaction to that published by PACKER et al. (2009, Molecular Ecology Resources 9, Suppl.1: 42–50), depreciating the value of traditional – especially morphological – data in taxonomical studies as “mediocre” and boosting instead the simplistic ‘barcoding’ procedures as “obviously effi cient”. Having explicitly stated my – as a ‘traditional’ taxonomist – ‘decalogue’, I show that a...

Cannon et al. (1995) describe pork “quality” as being associated with such characteristics as freshness, wholesomeness, grade, color (appearance), eating satisfaction and processing attributes (functionality). Grandin (1994) reported that ultimate pork quality is the responsibility given 50% to the producer and 50% to the packer. The producer is responsible for selection of swine genotypes that...

Shell egg microbiology has been studied extensively, but little information is available on how modern U.S. processing conditions impact microbial populations. As regulations are being drafted for the industry, such information can be important for determining processing steps critical to product safety. Five different shell egg surface microbial populations (aerobic bacteria, yeasts and molds,...
