• A comparison theorem for stability of linear stochastic implicit difference equations of Index-1A comparison theorem for stability of linear stochastic implicit difference equations of Index-1

    LSIDEs is generalization of linear stochastic difference equations, which have been well investigated in the literature, see [1-4]. They arise as mathematical models in various fields such as population dynamics, economics, electronic circuit systems or multibody mechanism systems with random noise (see, e.g. [5-8]. They can also be obtained fro...

  • The effect of residual la on crystal structure and magnetic properties of La1+Fe11.05Si1.95 compoundsThe effect of residual la on crystal structure and magnetic properties of La1+Fe11.05Si1.95 compounds

    Abstract: In this paper, we present the results of the study of the effect of residual La on crystal structure, magnetic properties of La1+Fe11.05Si1.95 ( = 0.00; 0.03; 0.06 and 0.09) compounds. The analysis of X-ray diffractions showed that when the La content increases to 9%, the structure still remains cubic in a typical NaZn13 arrangement ...

  • ℋ∞ Finite-time boundedness for discrete-time delay neural networks via reciprocally convex approachℋ∞ Finite-time boundedness for discrete-time delay neural networks via reciprocally convex approach

    Abstract: This paper addresses the problem of ℋ∞ finite-time boundedness for discrete-time neural networks with interval-like time-varying delays. First, a delay-dependent finite-time boundedness criterion under the finite-time ℋ ∞ performance index for the system is given based on constructing a set of adjusted Lyapunov–Krasovskii functionals ...

  • Absorption of isopropanol on surface of defect siliceneAbsorption of isopropanol on surface of defect silicene

    Abstract: In this work, we investigate the defect structure of silicene with a vancacy and the adsorption mechanism of isopropanol on the surface of defected silicene by employing the Density Functional Theory method. The adsorption profile was determined based on the van der Waals functional optPBE-vdW, and the charge transfer between isopropan...

  • A comparative study on two different methods for calculating gravity effect of an uneven layer: Application to computation of bouguer gravity anomaly in the east Vietnam sea and adjacent areasA comparative study on two different methods for calculating gravity effect of an uneven layer: Application to computation of bouguer gravity anomaly in the east Vietnam sea and adjacent areas

    Abstract: Calculation of gravity anomaly caused by an uneven layer is essential for quantitative interpretation. By comparing calculated anomalies with observed anomalies, we may infer some parameters of subsurface structures. There are many different methods for computing gravity effect of an uneven layer. This paper presents a comparative stud...

  • Nano titanium dioxide coated on multi-wall carbon nanotubes for photocatalytic applicationNano titanium dioxide coated on multi-wall carbon nanotubes for photocatalytic application

    Abstract. Titanium dioxide (TiO2) coated on multi-walled carbon nanotubes (CNTs) was synthesized with CNTs and TiO2 using the grinded method. The XRS spectra include that of the obtained single-phase anatase sample. The UV-Vis diffuse reflectance spectra show that the composite material can absorb at a higher wavelength and the absorption covers...
