    Opis:
    The aim of the paper is to describe heat transfer in the polycrystalline ceramic composite reinforced by metallic interfaces, i.e. metal matrix composites containing ceramic grains. Example of this kind of metal matrix composites is a two-phase material composed of brittle grains of WC joined by the plastic binder Co. Micromechanical modelling of the metal matrix composites response due to heat transfer was analysed numerically with the application of the finite element analysis. This process is very complicated due to the fact that the metal matrix composites material includes: elastic grains and inter-granular metallic layers that create its really complex internal structure. The heat transfer through 2 different phases is highly nonhomogeneous and leads to visible heat flux concentrations in the metallic phase.

    Opis:
    An iterative procedure of calculation of reflectivities and transmission coefficients of light rays for an uniaxial film with a lapse rate of an index of refraction on a uniaxial substrate was gained by orienting the axis of anisotropy along the normal to the boundary. With its help the dependences of ellipsometric angles Δ and ψ for a linear, quadratic, and sine-shaped profiles of refractive indices of a uniaxial immersing film with optic axis oriented along the normal to the boundary were analyzed. The dependences of angles Δ andψ on quantity of an uptake and anisotropy of the film were also examined. The numerical modelling for ZnO films and Langmuir-Blodgett-like films on a melted quartz was carried out, and this allowed to draw conclusions of practical importance for the ellipsometric investigations of the film structures.

    Opis:
    We have investigated the properties of structures incorporating graded index materials with parabolic permittivity profile. Surface-plasmon-polaritons at the interface of graded index material and semiconductor are studied by means of numerical simulations. We analyze the dependence of the dispersion characteristics on the graded index material profile as well as on the semiconductor concentration via the finite-difference time-domain simulations. Effects of the structure on dielectric and magnetic properties are taken into account by introducing the Drude model in the semiconductor dispersion.

    Opis:
    In this study, a counter flow convection-type dryer was designed and manufactured. During experiments, four different geometrical forms of pepper specimens were dried in a complete (unsliced), perforated, crosscut, and longitudinally sliced forms. For each type of red pepper specimens, the experiments have been conducted at air velocity level of 0.5 m/s, relative humidity of 10-15%, and temperature of 55-60°C. The theoretical mathematical model of drying process was developed, considering the pepper's bottom surface to be isolated. The drying curves of experimental results are compared to ones obtained from the theoretical analyses. The comparison showed that experimental results are consistent with the theoretical model. The best results, considering the drying duration, are collected from the specimens sliced longitudinally, which were followed by the crosscut specimens, perforated and unsliced-complete specimens, respectively. 82% water (humidity) content in 500 g sample was reduced to 4% in longitudinally cut samples, 6% in crosscut samples, 7.5% in perforated samples and 8% in unsliced-complete samples, after 14 hours of drying. It is suggested that regarding to easiness of processing, the crosscut red peppers are more suitable, compared to the other geometrical forms.

    Opis:
    We used a theory of thermo-hydrodynamics in quantum Hall system observed on a two-dimensional system in high magnetic fields at low temperatures, to investigate the electron temperature in the linear response regime. The variation of electron temperature exhibits an antisymmetric distribution of the incompressible strips. According to this result, we obtain effects of the electron temperature on the current density distribution using a Thomas-Fermi-Poisson approximation. We observe that incompressible strips change with increasing and/or decreasing the electron temperature with regard to the lattice temperature.
