by proposing a predictive method with no adjustable parameter and by using infinite dilution activity coefficients of components in binary mixtures obtained from unifac model, the binary interaction parameters (k12) in van der waals mixing rule (vdwmr) and orbey-sandler mixing rule (osmr) have been evaluated. the predicted binary interaction parameters are used in peng-robinson-stryjek-vera equ...

In this paper we propose an extension of the Cahn method [1] to binary mixtures and study the problem of wetting near a two-phase critical point without any assumption on the form of intermolecular potentials. A comparison between Cahn’s method and later works by Sullivan [2,3], Evans et al [4,5] is made. By using an expression of the energy of interaction between solid surface and liquids prop...

In this paper we present the first two-component, semi-empirical chromospheric model of the RS CVn binary system V 711 Tau based on detailed fits of Hα and Mg II h line profiles. Synthetic Hα and Mg II h line profiles are computed by means of NLTE radiative transfer calculations. Using the observed Emission Measure distribution to constrain the transition region structure and the photospheric N...

In a program instigated to understand close, possibly contact binary stars which appear to be in poor thermal contact, we have re-observed V432 Per both photometrically and spectroscopically. We conclude that the mass ratio is likely in the range q = 0.30–0.38, and the system clearly has a transit primary eclipse. The face of the less massive secondary towards the primary seems to be significan...

We previously reported a combinatorial strategy for designing alpha-helical proteins by assigning only the binary patterning of polar or nonpolar residues [Kamtekar, S., Schiffer, J. M., Xiong, H. Y., Babik, J. M., and Hecht, M. H. (1993) Science 262, 1680-1685]. Here we describe the finding that approximately half of the proteins in the original collection display some level of cooperativity i...

Two category Support Vector Machines (SVM) have been very popular in the machine learning community for the classification problem. Solving multicategory problems by a series of binary classifiers is quite common in the SVM paradigm. However, this approach may fail under a variety of circumstances. We have proposed the Multicategory Support Vector Machine (MSVM), which extends the binary SVM to...

The gas flow through porous media including that of multiple species is frequently described by the binary friction model (BFM) considering the binary diffusion, Knudsen diffusion, and viscous flow. Therefore, a numerical simulation was performed on a microporous support of an asymmetric oxygen transport membrane. As its exact numerical solution is complicated and not always possible, the resul...

Efficient packaging and communication of metadata are critical in multimedia communications to achieve seamless mobility. The XML schema compression proposed here comprises a method for decomposing an XML schema into a sequence of atomic elements. This representation reorganizes the given XML schema with the threefold purpose of facilitating dynamic schema switching and reconfiguration of metad...

We have developed a 3-D Monte Carlo radiative transfer model which computes line and continuum polarization variability for a binary system with an optically thick non-axisymmetric envelope. This allows us to investigate the complex (phase-locked) line and continuum polarization variability features displayed by many massive binaries: W-R+O, O+O, etc. An 8-way tree data structure constructed vi...
