a method based on the genetic algorithm (ga) was developed to study the phase behavior of multicomponent and multiphase systems. upon application of the ga to the thermodynamic models which are commonly used to study the vle, vlle and lle phase equilibria, the physically meaningful values for the binary interaction parameters (bip) of the models were obtained. using the method proposed in this ...

Accurate values of the thermal conductivity and specific heat of deuterium are necessary to make high quality cryogenic laser fusion targets. Due to the difficulty of measuring these values at cryogenic temperatures, the “3ω” method is used. This involves passing an oscillating current through a platinum wire embedded in deuterium and measuring the third-harmonic voltage that results from the t...

This paper considers the problem of effective feature extraction acoustic signals from oil and gas pipelines under different working conditions. A pipeline leakage detection method is proposed based on multi-feature entropy fusion local linear embedding (LLE). First, seven kinds commonly used which can reflect characteristics signal better are extracted through experiments, including permutatio...

Liquid-liquid equilibria for the (water + lactic acid + benzyl alcohol or p-xylene) ternary systems were investigated at atmospheric pressure and in the temperature range from 298.15-318.15 K. The studied systems exhibit two types of liquid-liquid equilibrium (LLE) behavior. The system consisting of benzyl alcohol displays type-1 LLE behavior, while a type-2 behavior is exhibited by th...

Abstract In this study, volatile compounds of various beans (black bean, mung and soybean) were analyzed on the basis particle sizes extraction temperatures by two methods, namely, distillation under reduced pressure–continuous liquid–liquid (DRP–LLE) hot water (HWE). The experimental results confirmed presence 10 components. five major hexanal, 2-methyl-1-butanol, 1-hexanol, 1-octen-3-ol benza...

In several articles, Shiffrin et al. (e.g., Shiffrin, Ratcliff, & Clark, 1990) argued that their data on the list-strength effect (LSE), in conjunction with their data on the list-length effect (LLE), are counter to current global matching memory models (GMMs). This is only true if one assumes that the memory system is reinitialized after every list, which is an unrealistic default assumption p...

LLE Review, Volume 71 101 The experimental program1 at LLE supports the national inertial confinement fusion (ICF) effort by performing experiments on OMEGA2 to investigate the requirements for attaining ignition using direct-drive targets on the National Ignition Facility. One of the primary challenges in direct-drive ICF is to minimize perturbations in the target that are created by nonunifor...

The locally linear embedding (LLE) algorithm is useful for analyzing sets of very different geoscientific images, ranging from smooth potential field images, to sharp outputs from modeling fracturing and fluid flows via cellular automata, to hand sketches of geological sections. LLE maps the very high-dimensional space embedding the images into 2-D, arranging the images on a plane. This arrange...

Liquid-Liquid Equilibrium (LLE) data are measured for the ternary mixtures of water + 1-butanol + butyl acetate and quaternary mixtures of water + 1-butanol + butyl acetate + glycerol at atmospheric pressure at 313.15 K. In addition, isothermal vapor–liquid–liquid equilibrium (VLLE) data are determined experimentally at 333.15 K. The region of heterogeneity is found to increase as the hydrophil...
