New spectroscopic binary companions of giant stars and updated metallicity distribution for binary systems [PDF]

open access: yes, 2016
We report the discovery of 24 spectroscopic binary companions to giant stars. We fully constrain the orbital solution for 6 of these systems. We cannot unambiguously derive the orbital elements for the remaining stars because the phase coverage is ...

Research on elecctro-sorption method for air conditioning system with binary solution [PDF]

open access: yesE3S Web of Conferences, 2021
Absorption air-conditioning system is a green air-conditioning system. With binary solution as the working fluid, the system performance is better with lower cost. To further improve the efficiency, an electrosorption method is proposed to regenerate the

Binary fuzzy linear programming problems: a new solution [PDF]

open access: yesتصمیم گیری و تحقیق در عملیات
Purpose: In this paper, a Binary Fuzzy Linear Programming Problem (BFLPP) with fuzzy objective function and fuzzy constraints is considered. This paper proposes a new approach that solves the problem based on Kerre's adapted method, which maintains the ...

Improvement of Component Flux Estimating Model for Pervaporation Processes

open access: yesMembranes, 2020
Separating non-ideal mixtures by pervaporation (hence PV) is a competitive alternative to most traditional methods, such as distillation, which are based on the vapour–liquid equilibrium (VLE).

Optimum Gabor filter design and local binary patterns for texture segmentation [PDF]

open access: yes, 2008
We present a novel approach to multi-texture image segmentation based on the formation of an effective texture feature vector. Texture sub-features are derived from the output of an optimized Gabor filter.

Periodic solutions of the Einstein equations for binary systems [PDF]

open access: yesPhysical Review D, 1994
This revision includes clarified exposition and simplified analysis. Solutions of the Einstein equations which are periodic and have standing gravitational waves are valuable approximations to more physically realistic solutions with outgoing waves. A variational principle is found which has the power to provide an accurate estimate of the relationship

Equilibrium, kinetic and thermodynamic biosorption studies of Hg(II) on red algal biomass of Porphyridium cruentum

open access: yesGreen Chemistry Letters and Reviews, 2016
Among a variety of microbial materials employed for biosorption, algae have added advantages of non-toxic and autotrophic nature. In this study, biosorption of Hg(II) was studied with red algal biomass of Porphyridium cruentum.

A Discrete Meta-Control Procedure for Approximating Solutions to Binary Programs

open access: yesEntropy, 2013
Large-scale binary integer programs occur frequently in many real-world applications. For some binary integer problems, finding an optimal solution or even a feasible solution is computationally expensive.

Characterization of the conglomerate form of acetyl-dl-leucine by thermal analysis and solubility measurements [PDF]

open access: yes, 2012
Starting from a mixture of enantiomers in solution, crystallization can generate different types of crystals. In order to determine which type of crystal is obtained in the case of acetylleucine, an active pharmaceutical ingredient (API), analytical ...
