Computer-Aided Design, 1984
The engineering drawing has never been particularly successful as either input or output medium for solid modelling techniques. This paper advances an alternative, interactive way of extracting dimensionally precise data from solid models. To help the user functions have been implemented which resemble the engineers hand measuring tools.

Modeling solid waste decomposition
Bioresource Technology, 2004The hydrolysis rate coefficients of sorted municipal waste were evaluated from the biochemical methane potential tests using non-linear regression. A distributed mathematical model of anaerobic digestion of rich (food) and lean (non-food) solid wastes with greatly different rates of polymer hydrolysis/acidogenesis was developed to describe the balance ...

Height probabilities in solid-on-solid models. II
Journal of Physics A: Mathematical and General, 1986For pt. I see ibid, vol.19, p.L923 (1986). The RSOS-3 model is a sequence of two-dimensional solid-on-solid models with integer heights restricted between 1 and r-1 and nearest neighbours differing by 0, 1 or -1. It has an exact solution manifold with four regimes of distinct physical behaviour along which the height probabilities in the bulk of the ...

Surface Diffusion in the Solid-on-Solid Model
Physical Review Letters, 1995We present results in 1+1 and 2+1 dimensions for surface diffusion controlled profile relaxation for the solid-on-solid model above and below the roughening transition. For all cases examined we found that the characteristic time scale [tau] for the decay of a sinusoidal profile scaled with the wavelength [ital L] as [tau][similar to][ital L][sup [ital

Solid-on-solid models of molecular-beam epitaxy
Physical Review E, 1994We discuss a number of solid-on-solid models that contain the two most important features of molecular-beam epitaxy: a flux of particles and relaxation of the growing film by surface diffusion. Evaporation of particles is not allowed and surface diffusion is driven by a Hamiltonian containing short-range interactions.

Abstract Solid modeling is the act of creating the three-dimensional models of various components and system using a computer-aided design (CAD) tool. This article describes the fundamental approaches of solid modeling, such as manufacturing operation simulation, parametric approach, and reference entities.

Growth in a restricted solid-on-solid model
Physical Review Letters, 1989Extensive simulations of growth in a stochastic ballistic deposition model on a (d-1)-dimensional substrate with a constraint on neighboring interface heights are described. The interface width obeys scaling even for small systems and grows as ${t}^{\ensuremath{\beta}}$ with \ensuremath{\beta}=1/(d+1). Generalizations to include irrevelant effects such

Generalized model for solid-on-solid interface growth
Physical Review E, 2015We present a probabilistic cellular automaton (PCA) model to study solid-on-solid interface growth in which the transition rules depend on the local morphology of the profile obtained from the interface representation of the PCA. We show that the model is able to reproduce a wide range of patterns whose critical roughening exponents are associated to ...

Kinetic models for solid-solid reactions
Thermochimica Acta, 1988Abstract The author develops two kinetic models for the reactions given by the chemical equation a A(s) + b B(s) → c C(s) + d D(s) occurring in powdered samples. One of the models deals with reactions limited by the nucleation on contact surfaces between grains, the other one with reactions limited by crystallization of products C and D.
