Abstract. We present a finite volume type scheme to solve a transport nephron model. The model consists in a system of transport equations with specific boundary conditions. The transport velocity is driven by another equation that can undergo sign changes during the transient regime. This is the main difficulty for the numerical resolution. The scheme we propose is based on an explicit resolut...

this paper introduces a new method for accelerating current sluggish fem and improving memory demand in fem problems with high node resolution or bulky structures. like most of the numerical methods, fem results to a matrix equation which normally has huge dimension. breaking the main matrix equation into several smaller size matrices, the solving procedure can be accelerated. for implementing ...

We present a detailed numerical study of solutions to the Zakharov–Kuznetsov equation in three spatial dimensions. The is three-dimensional generalization Korteweg–de Vries equation, though, not completely integrable. This L2-subcritical, and thus, exist globally, for example, H1 energy space. first stability solitons with various perturbations sizes symmetry, show asymptotic formation radiatio...

Conflict resolution algorithms (eRA) for broadcast communications have become increasingly popular since the work of Capetanakis as well as Tsybakov and Mikhailov (CfM-algorithm). In this paper we consider a class of CfM algorithms for which a common recurrence equation for the expected length of the conflict resolution interval is found. An analysis of the equation is the primary goal of this ...

We attempted a method of fusing a coarse resolution hyperspectral image and a high spatial resolution image with a few spectral bands to produce a high resolution hyperspectral image, and to extract the spectra of the end-members. The method is based on the linear spectral mixing model and an iterative maximum-likelihood algorithm is used to invert the mixing equation. The effects of noise and ...
