Abstract. We present results of noon–midnight meridional plane global hybrid-Vlasov simulations the magnetotail ion dynamics under a steady southward interplanetary magnetic field using Vlasiator model. The simulation show reconnection and formation earthward tailward fast plasma outflows. approach allows us to study velocity distribution functions (VDFs) that are self-consistently formed durin...

Groundwater contamination by nitrate is a globally growing problem due to the population growth and increase of demand for food supplies.Increasing nitrate concentrations in soil solution and leaching into the ground water table cause water pollution and disturbs the ecological balance. In addition to natural nitrogen cycle, nitrate can be entered to soil and water from the human waste, urban a...

SimOutUtils is a suite of MATLAB/Octave functions for studying and analyzing time series-like output from stochastic simulation models. More specifically, SimOutUtils allows modelers to study and visualize simulation output dynamics, perform distributional analysis of output statistical summaries, as well as compare these summaries in order to assert the statistical equivalence of two or more m...

Objective: In this paper, the authors describe the design, development and evaluationof specific simulation software for Cytogenetics training in order to demonstrate the usefulness of computer simulations for both teaching and learning of complex educational content. Background: Simulations have a long tradition inmedicine and can be very helpful for learning complex content, for example Cytog...

Statistical analysis tasks are increasingly encountered in the design of digital circuits that implement complex Boolean functions. Examples include analyzing the impact of soft errors, estimating power consumption, and stochastic computation. Common simulation techniques such as quasiMonte Carlo simulation often converge too slowly for large circuits with many inputs, i.e., many dimensions. We...

Block operations during simulation in Scicos and VSS environments can naturally be described as Nsp functions. But the direct use of Nsp functions for simulation leads to poor performance since the Nsp language is interpreted, not compiled. The methodology presented in this paper is used to develop a tool for generating efficient compilable code, such as C and ADA, for Scicos and VSS models fro...
