Identifying the cause of soil cadmium contamination with Monte Carlo mass balance modelling: a case study from Potosi, Bolivia KU Leuven
The Chayanta river in Potosi, Bolivia is polluted by present and past mining activities in the districts of Siglo XX and Llallagua. The river water, which is enriched with cadmium (Cd), is used for irrigation in the Quila Quila and Asiruri valleys where the median soil Cd concentration is 20 mg kg(-1), well above the background value of < 0.5 mg kg(-1). The objective of this study was to predict current soil contamination using a ...
Smart detectors for Monte Carlo radiative transfer Ghent University
Many optimization techniques have been invented to reduce the noise that is inherent in Monte Carlo radiative transfer simulations. As the typical detectors used in Monte Carlo simulations do not take into account all the information contained in the impacting photon packages, there is still room to optimize this detection process and the corresponding estimate of the surface brightness distributions. We want to investigate how all the ...
Procedures and guidelines for inputting and output smoothening of kinetic Monte Carlo distributions Ghent University
Population balance modeling is very popular in several branches of modern science, including (bio)chemical engineering, geography, and demography. A growing trend is the use of stochastic solvers (e.g., kinetic Monte Carlo), but care should be taken upon inputting and outputting distributed data for the populations involved. In the present contribution, several procedures and guidelines are formulated facilitating such data treatment. The ...
Monte Carlo calculation of beam quality correction factors in proton beams using PENH KU Leuven
This work calculates beam quality correction factors ([Formula: see text]) in both modulated and unmodulated proton beams using the Monte Carlo (MC) code [Formula: see text]. The latest ICRU 90 recommendations on key data for ionizing-radiation dosimetry were adopted to calculate the electronic stopping powers and to select the mean energy to create an ion pair in dry air ([Formula: see text]). For modulated proton beams, [Formula: see text] ...
Direct Simulation Monte Carlo modelling of the major species in the coma of comet 67P/Churyumov-Gerasimenko KU Leuven
© 2017 The Authors. We analyse the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) - the Double FocusingMass Spectrometer data between 2014 August and 2016 February to examine the effect of seasonal variations on the four major species within the coma of 67P/Churyumov- Gerasimenko (H2O, CO2, CO, and O2), resulting from the tilt in the orientation of the comet's spin axis. Using a numerical data inversion, we derive the ...
CMS Monte Carlo production operations in a distributed computing environment Vrije Universiteit Brussel
Monte Carlo production for the CMS experiment is carried out in a distributed computing environment; the goal of producing 30M simulated events per month in the first half of 2007 has been reached. A brief overview of the production operations and statistics is presented.
