✦ Synopsis

We deal in this paper with complex three-dimensional scenes, partitioned into several objects of any shape, and with varying local dimensions. We propose a consistent topological modeling of such scenes, based on a cellular model. We introduce a de"nition of simple elements for any adjacency graph-based geometrical structure. Then we prove a local characterization of simple cells of a cellular model, in the case of two objects, and of any number of objects. This characterization allows to de"ne homotopic deformations of a complex scene.

## Abstract Multi‐objective optimization of a venturi scrubber was carried out using a three‐dimensional model for collection efficiency and non‐dominated sorting genetic algorithm (NSGA). Two objective functions, namely (a) maximization of the overall collection efficiency, and (b) minimization of

A three-dimensional multi-level turbulence model is developed to simulate tide induced circulation in coastal waters. Based on the bathymetry data, the coastal waters are divided into a number of layers. In every layer, the velocities are integrated along the layer depth. The eddy viscosity and diff
