  1. 1. Tau-Leaping Implementations outside of chemistry

    Kandidat-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Lotta Kornö; [2024]
    Nyckelord :Tau leaping; Mathematics and Statistics;

    Sammanfattning : Tau-leaping is an algorithm for model simulations most often used in kinetic chemistry. It was created to make simulations more efficient at the cost of some accuracy. However, its uses outside of chemistry are limited but could help make some model simulations more efficient. LÄS MER

  3. 2. Modelling the effects of substituting pollinators in decline

    Kandidat-uppsats, Lunds universitet/Matematik LTH

    Författare :Axel Eriksson; [2023]
    Nyckelord :pollinators; plants; mutualism; competition; equilibrium populations; Mathematics and Statistics;

    Sammanfattning : While pollination is essential for many plant species and ecosystem functions, pollinator populations worldwide are declining. This decline is largely due to abiotic changes in the environment: climate change and other anthropogenic impacts, such as pesticides and land use change. LÄS MER

  4. 3. Solving Ordinary Differential Equations and Systems using Neural Network Methods

    Kandidat-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Författare :Mimmi Westrin; [2023]
    Nyckelord :Neural network methods; trial solutions; numerical methods; Lotka-Volterra system; SEIR model;

    Sammanfattning : The applications of differential equations are many. However, many differential equations modelling real-world scenarios are very complex and it can be of great difficulty to find an exact solution if one even exists. Thus, it is of importance to be able to approximate solutions of differential equations. LÄS MER

  5. 4. Dynamic simulation of transforming the transport system - Based on Lotka-Volterra population modelling

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Sara Saltvedt; [2022]
    Nyckelord :Electric Vehicles; Lotka-Volterra model; System Dynamics; Sustainable Vehicles; Sustainable transport system; Elfordon; Lotka-Volterra model; System Dynamics; Hållbara fordon; Hållbara transport system;

    Sammanfattning : The transport sector plays a critical role in meeting the targets of achieving net-zero emissions. In comparison to traditional fuel vehicles (ICEVs), new energy vehicles, such as electric vehicles (EVs), have advantages of energy-saving and emission reduction. LÄS MER

  7. 5. Spark for HPC: a comparison with MPI on compute-intensive applications using Monte Carlo method

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Shen Huije; Tingwei Huang; [2018]
    Nyckelord :;

    Sammanfattning : With the emergence of various big data platforms in recent years, Apache Spark - a distributed large-scale computing platform, is perceived as a potential substitute for Message Passing Interface (MPI) in High Performance Computing (HPC). Due to the limitations in fault-tolerance, dynamic resource handling and ease of use, MPI, as a dominant method to achieve parallel computing in HPC, is often associated with higher development time and costs in enterprises such as Scania IT.
