  1. 1. Exploring the Impact of Pseudo and Quasi Random Number Generators on Monte Carlo Integration of the Multivariate Normal Distribution

    University essay from Lunds universitet/Statistiska institutionen

    Author : Marcus Stolz; Jonathan Christopher; [2024]
    Keywords : Monte Carlo integration; Quasi monte carlo integration; Random number generation; Mathematics and Statistics;

    Abstract : This thesis examines the effects of pseudo and quasi-random number generators on the accuracy and efficiency of Monte Carlo Integration in the case of the multivariate normal distribution. The study compares the performance of the Mersenne Twister (a pseudo-random number generator) with Sobol and Halton sequences (quasi-random number generators). READ MORE

  2. 2. Is eXplainable AI suitable as a hypotheses generating tool for medical research? Comparing basic pathology annotation with heat maps to find out

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Albert Adlersson; [2023]
    Keywords : black box; eXplainable AI XAI ; Convolutional Neural Network CNN ; Mi- crosatellite Instability MSI ; colon cancer; gastric cancer; hypotheses generating; hypotheses generating tool; medical research;

    Abstract : Hypothesis testing has long been a formal and standardized process. Hypothesis generation, on the other hand, remains largely informal. This thesis assess whether eXplainable AI (XAI) can aid in the standardization of hypothesis generation through its utilization as a hypothesis generating tool for medical research. READ MORE

  3. 3. When is Electric Freight Cost Competitive? : Computational modeling and simulation of total cost of ownership for electric truck fleets

    University essay from Linköpings universitet/Institutionen för ekonomisk och industriell utveckling

    Author : Anton Zackrisson; [2023]
    Keywords : electric freight; battery-electric trucks; total cost of ownership; decision making under deep uncertainty DMDU ; cost-competitiveness; exploratory modeling and analysis EMA ; EMA workbench; quasi-Monte Carlo method; VRP; EVRP; elektrifiering; godstransport; elektriska lastbilar; total ägandekostnad; kostnadskonkurrenskraft; ruttoptimering;

    Abstract : Battery electric trucks (BETs) offer environmental benefits in terms of reduced carbon emissions and enhanced energy efficiency but have been challenged with economic viability compared to conventional internal combustion engine trucks (ICETs) caused by substantial acquisition costs, limited charging infrastructure, and concerns regarding range and payload capacity.  Previous studies focus on TCO at the vehicle or policy level but overlook the system and firm-level impacts.

  4. 4. Birds' Flight Range. : Sensitivity Analysis.

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Brian Masinde; [2020]
    Keywords : Flight; Sensitivity Analysis; Sobol indices; meta-modelling; quasi-Monte Carlo method;

    Abstract : ’Flight’ is a program that uses flight mechanics to estimate the flight range of birds. This program, used by ornithologists, is only available for Windows OS. It requires manual imputation of body measurements and constants (one observation at a time) and this is time-consuming. READ MORE

  5. 5. Sensitivity analysis and calibration of multi energy balance land surface model parameters

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Kim Friberg; [2017]
    Keywords : Physical Geography; Land Surface Model; Multi Energy Balance; Sensitivity Analysis; Parameter Calibration; Earth and Environmental Sciences;

    Abstract : Flows of energy between the atmosphere, the oceans and the land surfaces drive weather and climate on Earth. Increased understanding of these processes is crucial to successfully predict and address the challenges of climate change. READ MORE
