This paper presents an overview of different modelling and simulation (M & S) methods used in water treatment. Special emphasis is on pulp and paper industry. In chemical water treatment, M & S is successfully used in control design. Hybrid models based on a cascade approach are needed in biological wastewater treatment to cover different operating conditions. Uncertainty handling needs to be i...

Studies of hybrid zones have revealed an array of evolutionary outcomes, yet the underlying structure is typically characterized as one of three types: a hybrid zone, a hybrid swarm or a hybrid taxon. Our primary objective was to determine which of these three structures best characterizes a zone of hybridization between two divergent lineages of mule deer (Odocoileus hemionus), mule deer and b...

We describe the results of a hybrid matrix{Monte Carlo calculation of cascading of UHE cosmic rays and-rays through the cosmic background radiation elds over cosmological distances. We calculate the-ray and neutrino emission that results from the cascade, as well as the eeect of cascading on the primary spectrum. We discuss the results for various cosmic ray injection spectra and primary specie...

We consider digital feedback control systems with time-varying sampling periods consisting of an interconnection of a continuous-time nonlinear plant, a nonlinear digital controller and appropriate interface elements between the plant and controller (A/D and D/A converters). For such systems we study the stability properties of an equilibrium (in the Lyapunov sense) and apply these results in t...

A hybrid Monte Carlo-density matrix transport simulator is used to analyze the transport properties of resonant-phonon type terahertz quantum cascade lasers. By comparing calculated and experimental results, the importance of stimulated emission to the interpretation of experimental data is highlighted, particularly for devices based on diagonal radiative transitions. Finally, we discuss the ab...

A dispersive Landau-fluid model is used to study the decay and modulational instabilities of circularlypolarized Alfvén waves in a collisionless plasma, as well as their nonlinear developments. Comparisons are presented with the drift-kinetic approximation for the dispersionless regime and with hybrid simulations in more general conditions. The effect of the nature of the instability on particl...

In this study, we combined the ChIP-seq and the transcriptome data and integrated these data into signaling cascades. Integration was realized through a framework based on dataand model-driven hybrid approach. An enrichment model was constructed to evaluate signaling cascades which resulted in specific cellular processes. We used ChIP-seq and microarray data from public databases which were obt...

We study parallel (field-aligned) diffusion of energetic particles in the upstream of the bow shock with test particle simulations. We assume parallel shock geometry of the bow shock, and that MHD wave turbulence convected by the solar wind toward the shock is purely transverse in one-dimensional system with a constant background magnetic field. We use three turbulence models: a homogeneous tur...

Curve and surface thinning are widely-used skeletonization techniques for modeling objects in 3 dimensions. In the case of disordered porous media analysis, however, neither is really efficient since the internal geometry of the object is usually composed of both rod and plate shapes. This paper concludes an application of discrete wavelet transform (WT) and complex wavelet transform (CWT) in i...
