Parachor based expressions (basic and mechanistic) are often used to model the experimentally observed pressure dependence of interfacial tension (IFT) behaviors of complex supercritical carbon dioxide (sc-CO2) and crude oil mixtures at elevated temperatures. However, such modeling requires various input data (e.g. compositions and densities of the equilibrium liquid and vapor phases, and molec...

The power of any compiler is derived from, and also limited by, its program analyzers. Finding the right abstraction for program analysis is crucial in the development of compiler technology. For the abstraction to be useful, it must include sufficient information to support the code optimizations and transformations. In addition, it must be tractable to extract the information from at least a ...

Automatic Di erentiation is a technique that permits generation of adjoint programs, which compute gradients. In scienti c computation, these gradients are a fundamental tool for optimization or data assimilation. Computation of a gradient is relatively expensive, and should therefore be optimized whenever possible. The study of these program optimizations is most often based on the data-depend...

Though more diicult to program, distributed-memory parallel machines provide greater scalability than their shared-memory counterparts. Distributed Shared Memory (DSM) systems provide the abstraction of shared memory on a distributed machine. While DSMs provide an attractive programming model, they currently can not eeciently support all classes of scientiic applications. One such class are tho...

Data dependence analysis has become one of the most important constituents of loop-level parallelizing compilers. The information gathered from the analysis is needed to determine both the potential concurrency of loop nests and the legality of loop transformations concerning loop parallelization. The analysis is based on data dependence tests such as the constant test and the GCD test. Once th...

We use a Monte Carlo study to examine the consequences of using continuous distribution models to test for duration dependence when the data are reported in a discrete format. This specification error leads to mistaken evidence of duration dependence for sample sizes and parameter values likely to arise in empirical studies. We present and evaluate an approach that circumvents the misspecificat...

This paper proposes an efficient run-time system to schedule general nested loops on multiprocessors. The work extends existing one-dimensional loop scheduling strategies such as static scheduling, affinity scheduling and various dynamic scheduling methods. The extensions are twofold. First, multiple independent loops as found in different branches of parbegin/parend constructs can be scheduled...

conclusions metacognitive regulation strategies are more considerable prediction than emotional regulation strategies in sd group than in ad group. individuals with ad use alcohol as a means of both cognitive and emotional regulation strategy. patients and methods according to dsm-iv tr criteria, 45 patients with alcohol dependence (ad), 44 patients with substance dependence (sd), and 43 volunt...

conclusions opium was not identified as a risk factor of ischemic stroke. a more extended survey considering further confounding factors is recommended. background one of the supposed risk factors of ischemic stroke is opium addiction, while the researches about its prevalence among patients with stroke are limited. objectives the aim of this study was comparing the prevalence of opium addictio...

Boosting instruction level parallelism in dynamically scheduled processors requires a large instruction window. The approach taken by current superscalar processors to build the instruction window is known to have important limitations, such as the requirement of more powerful instruction fetch mechanisms and the increasing complexity and delay of the issue logic. In this paper we present a nov...
