  • Introduction to hydrodynamic modelling and granular dynamics The present text introduces hydrodynamic modelling principles in the context of batch wet granulation and coating systems and it reviews the latest achievements and proposals in the scientific literature in this field. The text concerns primarily the Eulerian and the Lagrangian modelling technique. In accordance with some of the latest published Ph.d. thesis in the field of hydrodynamics modelling, the Lagrangian technique is divided into a soft-particle and a hardsphere approach.

  • The final article in this section presents a modification to the Green’s function approach for modeling acoustic pressure, where the use of conformal mapping is replaced by a group of bound vortices. The author shows that the approach is readily extended to three dimensions. The method is discussed in the context of aircraft noise.

  • The system of three-dimensional hydrodynamic-environmental models could simulate full advection and dispersion processes of the dissolved and particulate matter as suspended sediment and all oil phases in the realistic marine conditions. The hydrodynamic model provides temperature, salinity and current structure and water level. These variables will be used in the environmental model simulating the advection and diffusion processes for suspended matter concentration, bottom sediment thickness and all oil spill phases in the water and bottom sediment.

  • The papers present the results of study on application of rainfall-runoff, channel routing models for improvement and extending forecast lead time and Diffusion Hydrodynamic Model (DHM) for inundation warning of Tra Khuc and Ve river basins. Keywords: Time of concentration Tc, update of forecast errors, flood forecast, inundation warning. 1. Introduction∗ For river basins in the central coastal provinces, the rivers has steep terrain, plains adjacent to the sea are relatively flat, so every year, floods and flash floods caused heavy damage to persons and property of people in the areas.

  • We have attempted to explain the concepts which have been used and developed to model the stochastic dynamics of natural and biological systems. While the theory of stochastic differential equations and stochastic processes provide an attractive framework with an intuitive appeal to many problems with naturally induced variations, the solutions to such models are an active area of research, which is in its infancy. Therefore, this book should provide a large number of areas to research further.

  • The use of open source softwares helps users learn the internal structure of numerical models. However, open source softwares usually require linking to auxiliary programs for data preprocessing, postprocessing, and visualization. The users also have to understand the problem thoroughly, and may at times modify the source code so that the model could better represent the natural mechanisms.

  • The litho-hydrodynamic and environmental conditions in the Vietnamese coastal estuarine basin are significantly affected by the land-ocean-atmosphere interaction processes whish tide has a determining role. Application of the coupled 1D, 2D and 3D modeling system could resolve this complicated problem but it requires other solutions related with the boundary and coupling conditions.

  • Since the dawn of civilisation human society has been shaped by its interaction with water—whether too much or too little. Indeed, water is one of the powerful forces of nature that have formed the planet on which we live. Floods are not new—they continually make news because of both tragic effects on individuals and acts of heroism in the emergency. The impact of floods on people can be dramatic even if there are no fatalities; pictures of rescue make good television material with stories told of bravery and fortunate escapes.

  • The recently published novel integrinaIIbb3 ectodomain crystallographic structure and NMR structures of its transmembrane⁄cytoplasmic segments were employed to refine previously developed molecular models. Alterna-tive complete aIIbb3 models were built and evaluated, and their shape was compared with EM maps and their computed hydrodynamic⁄conforma-tional properties were compared with the available experimental data.
