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

estimation of errors due to reduction in modal superposition method. Mode superposition methods are used to calculate the dynamic response of linear systems. In modal superposition method, it becomes unnecessary to consider all the modes of a particular system. In generally only a few number of modes contribute significantly to the solution. The main aim of the study is to identify the significant modes required for good approximation.

Abstract:
In the past few years, the growing popularity of mobile devices has made them attractive to virus and worm writers. One communication channel often exploited by mobile malware is the Bluetooth interface. In this paper, we present a detailed analytical model that characterizes the propagation dynamics of Bluetooth worms. Our model captures not only the behavior of the Bluetooth protocol but also the impact of mobility patterns on the Bluetooth worm propagation. Validation experiments against a detailed discrete-event Bluetooth worm si ....etc

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 the former is that e ....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

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
