Information on the vaporization processes and thermodynamic properties of glass-forming oxide melts in the systems MgO-B2O3-SiO2, CaO-B2O3-SiO2, SrO-B2O3-SiO2, BaO-B2O3-SiO2, PbO-B2O3-SiO2, CdO-B2O3-SiO2, ZnO-B2O3-SiO2, Bi2O3-B2O3-SiO2 and Bi2O3-GeO2-SiO2 together with the earlier obtained data is discussed. These data were obtained by high-temperature mass spectrometric method. Various types o...

In this article, multiple-product PVRP with pickup and delivery that is used widely in goods distribution or other service companies, especially by railways, was introduced. A mathematical formulation was provided for this problem. Each product had a set of vehicles which could carry the product and pickup and delivery could simultaneously occur. To solve the problem, two meta-heuristic methods...

binary decision diagram (bdd) is a data structure proved to be compact in representation and efficient in manipulation of boolean formulas. using binary decision diagram in network reliability analysis has already been investigated by some researchers. in this paper we show how an exact algorithm for network reliability can be improved and implemented efficiently by using cudd - colorado univer...

in this paper, we consider an arbitrary binary polynomial sequence {a_n} and then give a lower triangular matrix representation of this sequence. as main result, we obtain a factorization of the innite generalized pascal matrix in terms of this new matrix, using a riordan group approach. further some interesting results and applications are derived.

MnCo2O4 (MnO-Co2O3) nanocomposite as a binary oxide has been successfully prepared by precipitation method using cobalt nitrate and manganese nitrate as the precursors and then characterized by scanning electron microscopy-energy dispersive micro-analysis (SEM-EDX) and X-ray diffraction (XRD) techniques. In this work, we report the hydrolysis kinetics reactions of semi mustard (chloroethyl ethy...

Selectivity for specific analytes and high-temperature operation are key challenges chemiresistive-type gas sensors. Complementary hybrid materials, such as reduced graphene oxide (rGO) decorated with metal oxides enables realization of room-temperature sensors enhanced sensitivity. However, sensor training to identify target gases accurate concentration measurement from mixtures still remain v...

Metal oxides display a variety of crystal structures which often are more complicated compared to the parent metals [1]. In particular, the oxide structures grown on ordered aluminum binary alloys have been an immense challenge for scientists since decades [2]. On NiAl(110), oxygen binds to Al and forms an atomically thin layer of super-cell epitaxy with a huge unit cell. We investigate the str...
