Open AccessSimulation of Fluid Particle Cutting: Validation and Case Study
In this paper we present the comparison of experiments and numerical simulations for bubble cutting by a wire. The air bubble is surrounded by water. In the experimental setup an air bubble is injected on the...

A meshfree particle method for a vision-based macroscopic pedestrian model
In this paper we present numerical simulations of a macroscopic vision-based model (Degond et al. in Kinet Relat Models AIMs 6(4):809–839, 2013) derived from microscopic situation rules described in Ondřej et al....

Complex material flow problems: a multi-scale model hierarchy and particle methods
Material flow simulation is in increasing need of multi-scale models. On the one hand, macroscopic flow models are used for large-scale simulations with a large number of parts. On the other hand, microscopic ...

A Semi-Lagrangian Method for 3-D Fokker Planck Equations for Stochastic Dynamical Systems on the Sphere
In this paper, we consider stochastic dynamical systems on the sphere and the associated Fokker–Planck equations. A semi-Lagrangian method combined with a Finite Volume discretization of the sphere is presente...

Total oxidant-scavenging capacities of plasma from glycogen storage disease type Ia patients as measured by cyclic voltammetry, FRAP and luminescence techniques
It has been suggested that the very low incidence of atherosclerosis in glycogen storage disease type Ia (GSD Ia) subjects might be attributed to elevated levels of uric acid, one of the potent low-molecular-w...

Smoothed penalty algorithms for optimization of nonlinear models
We introduce an algorithm for solving nonlinear optimization problems with general equality and box constraints. The proposed algorithm is based on smoothing of the exact l 1-penalty func...

Multigrid Solution of Three-Dimensional Radiative Heat Transfer in Glass Manufacturing
We implement a multigrid algorithm to solve the radiative heat transfer equations in glass production. The time, angle and space coordinates are discretized using Crank-Nicolson, discrete-ordinate and Galerkin...

Optimal Control for Traffic Flow Networks
We consider traffic flow models for road networks where the flow is controlled at the nodes of the network. For the analytical and numerical optimization of the control, the knowledge of the gradient of the ob...

An Explicit Kinetic Model for Traffic Flow
Starting from a kinetic model we derive a macroscopic traffic equation, whereby we identify the appearing coefficients from the homogeneous stationary solutions of the underlying kinetic equation.

Longtime Behaviour of Stochastic Hamiltonian Systems: The Multidimensional Case
Hamiltonian systems perturbed by a white noise force are discussed in several dimensions. By using an appropriate scaling of the stochastic force a convergence theorem for the invariants of the deterministic m...

Enskog-like kinetic models for vehicular traffic
In the present paper a general criticism of kinetic equations for vehicular traffic is given. The necessity of introducing an Enskog-type correction into these equations is shown. An Enskog-like kinetic traffi...

On the connection of the formulas for entropy and stationary distribution
As is well known in statistical physics, the stationary distribution can be obtained by maximizing entropy. We show how one can reconstruct the formula for entropy knowing the formula for the stationary distri...

A kindred with Griscelli disease: Spectrum of neurological involvement
We report four members of a highly consanguineous family with silver-grey pigmentation of hair, two of whom had skin histology compatible with Griscelli disease. Unlike previously reported patients, they did n...

Acute pyelonephritis due to aKluyvera species in a child
AKluyvera sp. was recovered from the urine of a previously healthy 5-year-old child with clinical and laboratory evidence of acute pyelonephritis. This pathogen is usually a saprophyte and even when recovered in ...

Rearrangement and Activation of a Cellular Oncogene
The c-mos oncogene was shown to be rearranged in the murine plasmacytoma XRPC24. This resulted in transcription of this previously “silent” gene and in its activation as a malignant transforming gene as shown by ...
