Parametric optimisation in a 2-D cellular automata model of fundamental seismic attributes with the use of genetic algorithms
A two-dimensional (2-D) cellular automata (CA) dynamic system constituted of cells-charges has been proposed for the simulation of the earthquake process. In this paper, the study is focused on the optimal parameterisation of the model introducing the ...
Using a computational domain and a three-stage node location procedure for multi-sweeping algorithms
The multi-sweeping method is one of the most used algorithms to generate hexahedral meshes for extrusion volumes. In this method the geometry is decomposed in sub-volumes by means of projecting nodes along the sweep direction and imprinting faces. ...
Separation frequency analysis of interference fitted hollow shaft-hub connections by finite element method
Studies of interference fitted connections show that the traditional design method based on thick-wall cylinder theory has some limitations. Application of the finite element method for the elasto-plastic stress analysis of interference fitted ...
Terahertz spectroscopic uncertainty analysis for explosive mixture components determination using multi-objective micro-genetic algorithm
In practical applications, many suspicious samples may be a kind of mixture and consist of various chemical components that make the spectral analysis difficult. Various explosives and related compounds (ERC) in the mixture can be identified and the ...
Formulation of the Audze-Eglais uniform Latin hypercube design of experiments for constrained design spaces
Optimal Latin Hypercubes (OLH) created in a constrained design space might produce Design of Experiments (DoE) containing infeasible points if the underlying formulation disregards the constraints. Simply omitting these infeasible points leads to a DoE ...
1D unified mathematical model for environmental flow applied to steady aerated mixed flows
Hydraulic models available in literature are unsuccessful in simulating accurately and efficiently environmental flows characterized by the presence of both air-water interactions and free-surface/pressurized transitions (aka mixed flows). The purpose ...
Integrating rotation from angular velocity
The integration of the rotation from a given angular velocity is often required in practice. The present paper explores how the choice of the parametrization of rotation, when employed in conjuction with different numerical time-integration schemes, ...
An application of digital point cloud to historic architecture in digital archives
Currently, the process of conservation by digitizing historic buildings is a key technology in cultural heritage preservation that needs further improvement. However, a comprehensive survey of projects of digital archives shows that traditional, time-...
Towards building a cloud for scientific applications
The Cloud computing becomes an innovative computing paradigm, which aims to provide reliable, customized and QoS guaranteed computing infrastructures for users. This paper presents our early experience of Cloud computing based on the Cumulus project for ...
Irregular stock cutting system based on AutoCAD
This paper presents an irregular stock cutting system (NEST) developed on AutoCAD software platform. A detail description to its mechanism is included. This development is based on two known techniques: the bitmap representation to transform all shapes ...
Topology design of three-dimensional continuum structures using isosurfaces
Isolines Topology Design (ITD) is an iterative algorithm for the topological design of two-dimensional continuum structures using isolines. This paper presents an extension to this algorithm for topology design of three-dimensional continuum structures. ...
