5. 4. Resource Usage Prediction for Parameter Sweeps with Biochemical System Simulations

   University essay from Uppsala universitet/Tillämpad beräkningsvetenskap

   Author : Minjia Zhou; [2024]
   Keywords : ;

   Abstract : Exploring the behavior of biochemical systems when subjected to certain internal and external changes is fascinating, and these variations can be investigated through computational simulations. However, the computational cost of simulations is often quite high, necessitating an understanding of the computational requirements and resource utilization of these simulations. READ MORE

6. 5. A computational model of metapopulation dynamics and organism-mediated nutrient flow

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Amanda Hansson; [2023-08-07]
   Keywords : computational model; population dynamics; metapopulation dynamics; nutrient flow; simulation; spatially explicit; individual-based;

   Abstract : The aim of this project was to assess, using in-silico experiments, how different life history char-acteristics, such as age at maturity and dispersal ability of individuals, influence the dynamics of a metapopulation. To achieve this, a novel model of a spatially explicit metapopulation, with organ-ism-mediated nutrient flow between fragmented habitat patches, was implemented by means of computer simulations.
