Some aspects of modelling segmentation processes
Introduction The world we live in is continually changing. The images formed on the retina in vision are a sequence of varying, shifting intensities. In hearing, likewise changes in frequency and intensity are recognised to form the basis of our detecting the underlying structure of events in the world. Research in music perception has identified the significance of change in the segmentation o...
متن کاملEquivalent roughness of gravel-bed rivers
The relation between the equivalent roughness and different grain size percentiles of the sediment in gravel-bed rivers was determined under the hypothesis that the vertical distribution of the flow velocity follows a logarithmic law. A set of 954 data points was selected from rivers with gravel size sediment or larger, with a non-sinuous alignment and free of vegetation or obstacles. According...
متن کاملModeling of chemical and physical processes in reactive porous bed
This paper contains the description of pyrolysis and flow process through porous media taking into account kinetic rate coefficient and equilibrium state of pyrolysis. Mathematical equation of pyrolysis mechanism including kinetic rate coefficient and equilibrium rate of pyrolysis, and equations like mass, momentum and energy and flow through porous zone are presented. Considered model is based...
متن کاملMathematical Modeling of Gas Adsorption Processes in Packed Bed: The Role of Numerical Methods on Computation Time
Rigorous mathematical modeling of adsorption processes in packed beds involves time-consuming computations which are considered as the fundamental weakness of such thorough mathematical models. Thus, reducing the computation time was a key factor in improving adsorption mathematical models. In order to achieve this goal, an attempt was made to know how much using different numerical methods inf...
متن کاملSome aspects on designing for metal Powder Bed Fusion
Additive Manufacturing (AM) using the Powder Bed Fusion (PBF) is a relatively new manufacturing method that is capable of creating shapes that was previously practically impossible to manufacture. Many think it will revolutionize how manufacturing will be done in the future. This thesis is about some aspects of when and how to Design for Additive Manufacturing (DfAM) when using the PBF method i...
