  1. 11. Squaring VEGAS -- Multidimensional Integration Using 2D Correlations

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Philip Siemund; [2021]
    Nyckelord :statistics; numerical integration; Monte Carlo integration; VEGAS; Physics and Astronomy;

    Sammanfattning : Multidimensional integrals are used in many areas of physics; electrodynamics, quantum mechanics and statistical physics, to name a few. Many integrals can not be solved analytically, but can instead be approximated numerically. VEGAS is a Monte Carlo integration algorithm, which specializes it in approximating multidimensional integrals. LÄS MER

    Sammanfattning : In recent years, the Helicon Plasma Thruster (HPT) has become one of the most promising technologies of in-space electric propulsion. T4i Technology for Propulsion and Innovation S.P.A. LÄS MER

  4. 13. Analysis and optimal design of a titanium aircraft bracket using topology optimization

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Vincent Curwen; Alexander Saxin; [2021]
    Nyckelord :Topology optimization; TOSCA; finite element method; aircraft engine bracket; multi-objective topology optimization; additive manufacturing;

    Sammanfattning : Sustainable engineering within product development is becoming increasingly important with the ever-growing amounts of resources used to sustain the human way of life in modern times. An effective way of helping to deal with this problem is to reduce the resources used in products and components across the world. LÄS MER

  5. 14. Micro-architectured materials for noise and vibration control in high voltage products – design and modelling

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanik

    Författare :Alec Chamberlain; [2021]
    Nyckelord :Microarchitectured; lattice; elasticity; viscoelasticity; computational; homogenization;

    Sammanfattning : Many Hitachi ABB Power Grids (HAPG) products vibrate and emit noise, but legal limitations of these parameters fuel the development of energy absorption methods used on products. Methods such as Constrained Layer Damping (CLD). LÄS MER

  7. 15. Physics-Informed Machine Learning in Power Transformer Dynamic Thermal Modelling

    Master-uppsats, KTH/Matematisk statistik

    Författare :Federica Bragone; [2021]
    Nyckelord :ANN; PINN; PDE; FVM; Transformer; Thermal modelling; ANN; PINN; PDE; FVM; Transformatorer; Termisk modellering;

    Sammanfattning : Artificial neural networks (ANNs) are commonly considered as "black boxes": they can approximate any function without giving any interpretation. Novel research has observed that the laws of physics, which govern everything around us, can supplement the implementation of a neural network. LÄS MER
