The paper expresses a mathematical model of homogeneous gas motion with respect to formation processes and the growth condensation nuclei. Since condensed particles are small, research is carried out single velocity model. results obtained have shown that application cylindrical tube leads nonlinear flow effects. responds to: geometrical exposure related transition from conical diverging nozzle

Deepfakes, one of the most novel forms misinformation, have become a real challenge in communicative environment due to their spread through online news and social media spaces. Although fake existed for centuries, its circulation is now more harmful than ever before, thanks ease production dissemination. At this juncture, technological development has led emergence deepfakes, doctored videos, ...

The optimum design of the microchannel heat sinks needs to consider both transfer and pressure drop limitations microchannel. In this paper, a novel configuration sink is proposed obtain improved thermo-hydraulic performance. includes porous fins that form adjacent converging–diverging channels. Three-dimensional steady laminar simulations were conducted access performance compare it with conve...

The self-similar converging-diverging shock wave problem introduced by Guderley in 1942 has been the source of considerable mathematical and physical interest. We investigate a novel application of the Guderley solution as a unique and challenging code verification test problem for compressible flow algorithms; this effort requires a unified understanding of the problem’s mathematical and compu...

A ten layer feed-forward network characterized by diverging/converging patterns of projection between successive layers of regular spiking (RS) neurons is activated by an external spatiotemporal input pattern fed to Layer 1 in presence of stochastic background activities fed to all layers. We used three dynamical systems to derive the external input spike trains including the temporal informati...

The present paper develops and validates a numerical procedure for the calculation of turbulent combustive flow in converging and diverging ducts and through simulation of the heat transfer processes, the amount of production and spread of Nox pollutant has been measured. A marching integration solution procedure employing the TDMA is used to solve the discretized equations. The turbulence mode...

We perceive perspective angles, that is, angles that have an orientation in depth, differently from what they are in physical space. Extreme examples are angles between rails of a railway line or between lane dividers of a long and straight road. In this study, subjects judged perspective angles between bars lying on the floor of the laboratory. Perspective angles were also estimated from pictu...

The problem of resonance trapping is further analyzed by the consideration of a quasi Hamiltonian model, which is the classical one-degree-of-freedom Hamiltonian model, modified by the inclusion of a nonconservative term for the derivative of the momentum. A new formulation to compute capture probabilities is deduced, which is a function of the particular nonconservative force involved. The new...
