A Dialectic Analysis of Generativity: Issues of Network-Supported Design in Mathematics and Science

Autor: Walter M. Stroup, Nancy Ares, Andrew C. Hurford

Publikováno v: Mathematical Thinking and Learning. 7:181-206

New theoretical, methodological, and design frameworks for engaging classroom learning are supported by the highly interactive and group-centered capabilities of a new generation of classroom-based networks. In our analyses, networked teaching and le

Three-Dimensional Convection in Horizontal Cylinders: Numerical Solutions and Comparison with Experimental and Analytical Results

Autor: A. C. Hurford, Patrick Bontoux, G.H. Schiroky, F. Rosenberger, C. Smutek, Bernard Roux, G. de Vahl Davis

Publikováno v: Numerical Heat Transfer, Part B: Fundamentals. 8:613-631

The results of a three-dimensional numerical simulation of Boussinesq free convection in a horizontal differentially heated cylinder are presented. The computation was based on a Samarskii-Andreyev scheme (described by Leong, 1981) and a false-transi

Sintering behaviour and properties of SiCAION ceramics

Autor: Andrew C. Hurford, Anil V. Virkar, Raymond A. Cutler, Jow-Lay Huang

Publikováno v: Journal of Materials Science. 21:1448-1456

Silicon carbide (SiC), aluminium oxycarbide (AI2OC), and aluminium nitride (AlN) all have the same wurtzite crystal structure and can be processed so as to form SiCAION, an acronym for the solid solution. This paper describes processing of SiC-Al2OC

Pressureless-sintered Al2O3-TiC composites

Autor: Andrew C. Hurford, Raymond A. Cutler, Anil V. Virkar

Publikováno v: Materials Science and Engineering: A. :183-192

Titanium carbide (TiC) (typically 30 wt.% TiC is used in cutting tools) dispersed in an alumina (Al 2 O 3 ) matrix improves the hardness over that of an Al 2 O 3 cutting tool, principally by limiting Al 2 O 3 grain growth. Al 2 O 3 -TiC composites ha

Numerical solutions and experimental results for three dimensional buoyancy driven flows in tilted cylinders

Autor: G. de Vahl Davis, Patrick Bontoux, G.P. Extrémet, C. Smutek, A. Randriamampianina, A. C. Hurford, F. Rosenberger, Bernard Roux

Publikováno v: Advances in Space Research. 6:155-160

Finite difference solutions and experiments are presented for free convection in differentially heated cylinders when the inclination varies with respect to the gravity vector. The results are compared with asymptotic solutions in horizontal cylinder
