We study, in the fluid flow framework, the cooperative dynamics of a buffered production line in which the production rate of each work-cell does depend on the content of its adjacent buffers. Such state dependent fluid queueing networks are typical for people based manufacturing systems where human operators adapt their working rates to the observed environment. We unveil a close analogy betwe...

We study non-equilibrium behaviors of a particle subjected to high-frequency cutoff noise in terms generalized Langevin equation, where the spectrum internal is considered be Debye form. A closed solution impossible even if equation linear, because Laplace transform memory kernel multi-value function. use numerical method calculate velocity correlation function force-free and probability passin...

In this paper we show an approach to electron transport in double barrier structures which unifies the well known sequential and resonant tunneling models in the widest range of transport regimes, from completely coherent to completely incoherent. In doing so, we make a clear distinction between “approaches” and “transport regimes,” in order to clarify some ambiguities in the concept of sequent...

The problem of tsunami wave generation by variable meteo-conditions is discussed. The simplified linear and nonlinear shallow water models are derived, and their analytical solutions for a basin of constant depth are discussed. The shallow-water model describes well the properties of the generated tsunami waves for all regimes, except the resonance case. The nonlinear-dispersive model based on ...

We study the non-Markovian quantum dynamics of an emitter inside an open multimode cavity, focusing on the case where the emitter is resonant with high-frequency cavity modes. Based on a Green’s-function technique suited for open photonic structures, we study the crossovers between three distinct regimes as the coupling strength is gradually increased: (i) overdamped decay with a time scale giv...

Magnetic field properties at the plasma edge in the Dynamic Ergodic Divertor ~DED! for the Torus Experiment for Technology Oriented Research ~TEXTOR-94! @Fusion Eng. Des. 37, 337 ~1997!# have been studied. This is done by using a generalized symplectic mapping method of integration of field line equations. It is shown that by the radial shift of the resonant magnetic surfaces implemented by cha...

This paper presents a feature set selection procedure, which is implemented in the frequency domain and involves developing a modified CPS feature set that incorporates power information. Metric distances between the respective modified CPS at several target resonant frequencies are computed and are used to form the final feature set. Stationary individual targets in free space were used to dis...

We consider a one–dimensional coupled stationary Schrödinger drift–diffusion model for quantum semiconductor device simulations. The device domain is decomposed into a part with large quantum effects (quantum zone) and a part where quantum effects are negligible (classical zone). We give boundary conditions at the classic– quantum interface which are current preserving. Collisions within the qu...

We analyze pattern formation in doubly resonant intracavity second-harmonic generation in the presence of competing nondegenerate parametric downconversion. We show that for positive cavity detuning of the fundamental frequency the threshold for parametric oscillation is lower than that of transverse, pattern forming instabilities. The parametric oscillation strongly modifies the pattern dynami...

We have applied two different simulation models for the stationary carrier transport and optical gain analysis in resonant phonon depopulation THz Quantum Cascade Lasers (QCLs), based on the semiclassical ensemble Monte Carlo (EMC) and fully quantum mechanical non-equilibrium Green’s functions (NEGF) method, respectively. We find in the incoherent regime near and above the threshold current a q...
