  1. 1. Path Choice Estimation in Urban Rails : Asimulation based optimisation for frequency-based assignment model

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Alexander Adolfsson; [2022]
    Keywords : Black-Box Optimisation; Optimization; Simulation based optimisation; Transit Network; Automaton; Urban Transport; Public transportation; Black-Box optimering; Optimering; Simuleringsbaserad Optimering; Transportsystem; Automation; Local Transport; Kollektivtrafik;

    Abstract : Transit system have a large importance in modern urban cities, with urban rail often acting as the central system with it efficient travel time and great capacity. As cities grow in population, so to does the usage of urban rail resulting in increased crowding on the platform and in the trains. READ MORE

  3. 2. Stochastic Lateral Transshipment within the Fast Fashion Industry

    University essay from KTH/Matematik (Inst.)

    Author : Linnéa Andersson; [2022]
    Keywords : Degree Project; Fast Fashion; H M; Lateral Transshipment; Linear Optimization; Master’s Thesis; Recourse Problem; Retail; Sample Average Approximation; Stochastic Optimization; Transshipment; Two-Stage Recourse Problem; Detaljhandel; H M; Lagerflyttar; Lagerhantering; Linjär optimering; Masters Examensarbete; Mode; Optimering; Snabbt mode; Stokastisk optimering; Transportproblem;

    Abstract : In an industry with highly variable demand and a fickle customer demanding a fast changing supply, quickly responding to the customer becomes crucial for the fast fashion retailer. Using lateral transshipment, one is able to reorganize supply within an echelon of the supply chain to quickly respond to the forecasted demand by looking at shorter more accurate forecasts and act accordingly.

  4. 3. Multiscale numerical approximation of morphology formation in ternary mixtures with evaporation : Discrete and continuum models for high-performance computing

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Author : Mario Setta; [2021]
    Keywords : ;

    Abstract : We propose three models to study morphology formations in interacting ternary mixtures with the evaporation of one component. Our models involve three distinct length scales: microscopic, mesoscopic, and respectively, macroscopic. READ MORE

  5. 4. Reissner Mixed Variational Theorem for Ritz Sublaminate Generalized Unified Formulation

    University essay from KTH/Lättkonstruktioner

    Author : Pier Antonio Esposito; [2021]
    Keywords : Mechanics; FEM; Ritz; Reissner; Stress; deformations; composite materials; Mekanik;

    Abstract : This thesis is about the development of a new numerical method for the analysis of composite shells. The present work is based on Reissner Mixed Variational Theorem (RMVT), the Sublaminate Generalized Unified Formulation (S-GUF), and the Ritz approximation. READ MORE

  6. 5. A numerical investigation of Anderson localization in weakly interacting Bose gases

    University essay from KTH/Numerisk analys, NA

    Author : Crystal Ugarte; [2020]
    Keywords : Applied mathematics; finite elements; eigenvalue solver; eigenvalue problem; Bose-Einstein Codensate; Finita elementmetoden; tillämpad matematik; Bose-Einstein kondensat; egenvärdesalgoritm; egenvärdesproblem;

    Abstract : The ground state of a quantum system is the minimizer of the total energy of that system. The aim of this thesis is to present and numerically solve the Gross-Pitaevskii eigenvalue problem (GPE) as a physical model for the formation of ground states of dilute Bose gases at ultra-low temperatures in a disordered potential.
