  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. Deep neural network for object classification and optimization algorithms for 3D positioning in Ultrasonic Sensor Array

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Hui Zhang; [2021]
    Keywords : ultrasonic sensor; simulation; CNN; optimization; localization; object classification;

    Abstract : Ultrasonic sensors are commonly used in automobiles to assist driving maneuvers, e.g., parking, because of their cost-effectiveness and robustness. READ MORE

  4. 3. Modeling Far Ultraviolet Auroral Ovals at Ganymede

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

    Author : Carl Daniel Ahlberg; Wera Mauritz; [2018]
    Keywords : ;

    Abstract : Ganymede, one of Jupiters moons, differs from other moons in the Solar System as it has its own magnetic field. This rare property shapes the morphology on the existing far ultraviolet oxygen auroral ovals on the celestial body in the northern and southern hemisphere created by high energy electrons colliding into the atmosphere.

  5. 4. High Performance Multi-Objective Voyage Planning Using Local Gradient-Free Methods

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Niklas Fejes; [2016]
    Keywords : optimization; voyage planning; local gradient-free methods; nelder-mead simplex; subplex;

    Abstract : A number of parallel gradient-free local optimization methods are investigated in application to problems of voyage planning for maritime ships. Two optimization algorithms are investigated, a parallel version of the Nelder-Mead Simplex method and the Subplex method with Nelder-Mead Simplex as its inner solver. READ MORE

  6. 5. Individualization of fixed-dose combination regimens : Methodology and application to pediatric tuberculosis

    University essay from Uppsala universitet/Institutionen för farmaceutisk biovetenskap

    Author : Gunnar Yngman; [2015]
    Keywords : pharmacometrics; pharmacokinetics; PK; population pharmacokinetics; optimal design; FDC; fixed-dose combination; pediatrics; tuberculosis; rifampicin; pyrazinamide; isoniazid; ethambutol; modeling; simulation; estimation; allometric scaling; stochastical simulation and estimation; NONMEM; MATLAB; FO; FOCE; Expectation-Maximization algorithm; importance sampling; Nelder-Mead method; logistic function; discontinuity; euclidean distance; Sammon mapping; global minimum; local minima;

    Abstract : Introduction: No Fixed-Dose Combination (FDC) formulations currently exist for pediatric tuberculosis (TB) treatment. Earlier work implemented, in the software NONMEM, a rational method for optimizing design and individualization of pediatric anti-TB FDC formulations based on patient body weight, but issues with parameter estimation, dosage strata heterogeneity and representative pharmacokinetics remained.
