    Notes: Abstract. We examine in detail the asymptotic behaviors of the number of comparisons used in Batcher's sorting algorithm and a quantity arising in analyzing the rectangle heuristic for finding minimum Euclidean matching due to Supowit and Reingold. We put forth methods (elementary and analytic) for computing the Fourier coefficients of periodic functions appearing in the asymptotic expansions of these quantities. The methods consist of the approach by Flajolet and Golin for divide-and-conquer recurrences and van der Corput's method from analytic number theory for exponential sums.

    Description / Table of Contents: Riassunto Si è fatta un'analisi teorica per studiare la cinetica coinvolta nella crescita del cristallo di CuInS2 col metodo del riscaldatore mobile. Si sviluppa uno schema numerico per calcolare il gradiente di temperatura in ogni punto del sistema. Si è ottenuta una stima numerica del valore di massimo accrescimento come suggerimento per stabilire la velocità di spostamento del riscaldatore nell'esperimento pratico.

    Notes: Summary A theoretical analysis has been carried out to investigate the kinetics involved in the CuInS2 crystal growth by the travelling-heater method. A numerical scheme is developed to compute the temperature gradient at any point inside the system. A numeric estimate of the maximum growth rate was obtained as a suggestion for setting the travelling speed of the heater in the practical experiment.

    Description / Table of Contents: Riassunto È stata condotta un'analisis teorica per studiare la cinetica implicata nella crescita CVD di CuInS2. Si assume un modello a strato stagnante per la simulazione numerica. Si ottengono risultati di calcolo per il tasso di crescita in funzione della temperatura del substrato, la velocità media del gas e le pressioni parziali nel tubo di reazione. Questa analisi indica che la temperatura del substrato gioca un ruolo dominante nel tasso di crescita, che è consistente con i dati sperimentali.
    Abstract: Резюме Теоретически исследуется кинетика роста кристаллов CuInS2 посредством химического осаждения пара. Для численного моделирования предполагается слоистая модель. Получены численные результаты для скорости роста в зависимости от температуры подложки, средней скорости газа и парциальний в реакторе. Проведенный анализ показывает, что температура подложки играет существенную роль в определении скорости роста, что согласуется с нашими экспериментальными результатами.
    Notes: Summary A theoretical analysis has been carried out to investigate the kinetics involved in the CVD growth of CuInS2. A stagnant-layer model is assumed for the numerical, simulation. Computational results for the growth rate as a function of the substrate temperature, mean, gas velocity and partial pressures in the reaction tube are obtained. This analysis indicates that the substrate temperature plays a dominant role in the growth rate, which is consistent with our experimental data.

    The effects of metal coating on the diffusion bonding in Al2O3/Inconel 600 and the modulus of rupture strength of alumina (1996)
    Springer
    Journal of materials science 31 (1996), S. 2429-2435 
    Details
    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Alumina with a sputter-deposited metal film was diffusion bonded to Inconel 600. A higher bonding strength and lower joining temperature were obtained with titanium coating compared to that for the non-coated sample. The improved joining behaviour was attributed to an enhanced interface reaction and reduction in the thermal stress. Also, the effect of various coatings of 3 μm thickness on the mechanical property of alumina after heat treatment at 1000 °C for 30 min under 10−6 torr vacuum was evaluated in terms of modulus of rupture (MOR) using a Weibull plot. While the Cu coating did not change MOR strength of alumina, the reactive Ti and Zr metal coatings caused a noticeable reduction in averaged MOR strength. The effect of co-sputtering of Ti-Cu, and bilayer coatings of Cu/Ti and Ti/Cu was also investigated.

    A new kinetic model for rapid granular flow (1995)
    Springer
    Continuum mechanics and thermodynamics 7 (1995), S. 357-384 
    Details
    ISSN: 1432-0959
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The fluid motion of an assemblage of cohesionless granules is governed by the balance laws of mass, momentum and energy and is special because due to the variability of the mean free path of the particles the density is not preserved and the particle fluctuation energy (= granular temperature) is determined together with the mean fields. Constitutive equations are postulated for the dispersive pressure, viscosity, “thermal diffusivity” and energy annihilation rate in terms of the mean free path length, the time of encounter between two collisions and geometric and dynamic quantities via dimensional arguments. The model defines the time of encounter to consist of the free flying time between collisions plus the contact duration. The inclusion of the latter brings in the elasticity of the particles and introduces a relaxation mechanism that explains the typical behaviour of shear and fluidized layers better than has been done by previous models.

    Notes: Abstract. The fluid motion of an assemblage of cohesionless granules is governed by the balance laws of mass, momentum and energy and is special because due to the variability of the mean free path of the particles the density is not preserved and the particle fluctuation energy (=granular temperature) is determined together with the mean fields. Constitutive equations are postulated for the dispersive pressure, viscosity, "thermal diffusivity" and energy annihilation rate in terms of the mean free path length, the time of encounter between two collisions and geometric and dynamic quantities via dimensional arguments. The model defines the time of encounter to consist of the free flying time between collisions plus the contact duration.
