Introduction

The most fundamental consideration in CFD is how one treats a continuous fluid in a discretized fashion on a computer. One method is to discretize the spatial domain into small cells to form a volume mesh or grid, and then apply a suitable algorithm to solve the equations of motion (Euler equations for inviscid, and Navier-Stokes equations for viscid flow). In addition, such a mesh can be either irregular (for instance consisting of triangles in 2D, or pyramidal solids in 3D) or regular; the distinguishing characteristic of t ....etc

Abstract
Analysis of stability is essential for power systemplanning and stable operation. The results of transient andsteady-state stability studies depend on the appropriatechoice of load models. This study investigates modelingissues of the induction motors that are used as a dynamicpart of load models. Due to its superiority, we propose theapplication of the rotor speed frame based model ofinduction motors instead of a system frequency frame basedmodel in power system stability simulations. A comparativestudy of steady-state stabi ....etc

In recent years subcritical multiplying structures driven by an external neutron source have been proposed for long-lived product transmutation and for safe and acceptable energy production. The study of the dynamics of these systems needs the adaptation of current methods in order to properly reproduce the peculiar features of source-driven systems.The seminar addresses the recent activities carried out by the Reactor Physics Group of Politecnico di Torino on the neutron kinetics of source-driven systems. The basic physical aspects of the time ....etc

Mechanical cutting of visco-elastic polymers is experimentally investigated using sharp knives. The knife is aligned orthogonally to the substrate's surface, and is forced into the substrate. Two cutting scenarios are investigated i) plunge cutting, where the knife edge moves directly into the substrate, and ii) slicing, where the knife shears tangentially as it moves into the substrate. For slicing fracture lines emanating from the cut are observed, and the threshold forces for cutting are considerably smaller, indicating that the two cutting ....etc

Definition
The term group dynamics implies that individual behaviours may differ depending on individuals' current or prospective connections to a sociological group. Group dynamics is the field of study within the social sciences that focuses on the nature of groups.

Urges to belong or to identify may make for distinctly different attitudes (recognized or unrecognized), and the influence of a group may rapidly become strong, influencing or overwhelming individual proclivities and actions. The group dynamics may also include changes in beha ....etc
