  1. 1. Trajectory Optimisation of a Spacecraft Swarm Maximising Gravitational Signal

    University essay from KTH/Optimeringslära och systemteori

    Author : Rasmus Maråk; [2023]
    Keywords : Spacecraft Swarms; Trajectory Optimisation; Impulsive Manoeuvres; Evolutionary Algorithms; Polyhedral Gravity Model; Small Body Exploration; Discrete Spherical Grids; Svärmande rymdfarkoster; Banoptimering; Impulsiva manövrar; Evolutionära Algoritmer; Polyhedral gravitationsmodell; Utforksning av små kroppar i solsystemet; Diskreta sfäriska rutnät;

    Abstract : Proper modelling of the gravitational fields of irregularly shaped asteroids and comets is an essential yet challenging part of any spacecraft visit and flyby to these bodies. Accurate density representations provide crucial information for proximity missions, which rely heavily on it to design safe and efficient trajectories. READ MORE

  3. 2. Optimising the Planning- and Scheduling in a Complex Production : Discrete-Event Simulation in a pharmaceutical context

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Johan Börjesson; Paulina Boutros; [2022]
    Keywords : DES; Optimisation; Pharmaceutical industry; Product mix; Production planning- and scheduling; Resource allocation; Simulation.; DES; Läkemedelsindustrin; Optimering; Produkt mix; Produktionsplanering- och schemaläggning; Resursfördelning; Simulering;

    Abstract : The aim of this study is to investigate the optimisation of production planning- and scheduling in a pharmaceutical facility using DES.Research questions: “How can DES be used to achieve flexibility and efficiency in a pharmaceutical facility?” and “How can DES be used to increase efficiency of the resource allocation in a pharmaceutical facility?”Methodology: This study has been compared to a deductive- and a quantitative research approach where a process simulation has been modelled.

  4. 3. Optimisation through automation : Implications and opportunities of bin picking in manufacturing

    University essay from Blekinge Tekniska Högskola/Institutionen för industriell ekonomi

    Author : Enzo Seiholm; Jesper Sundius; [2022]
    Keywords : Industry 4.0; Bin picking; Discrete event simulation; KPI; Utility function;

    Abstract : Background Manufacturers have to adopt modern technologies to compete at the top of their field. However, adopting new technologies can be expensive and difficult to validate prior to implementation. One technology that has difficulties receiving a wider application is bin picking. READ MORE

  5. 4. Nuclear Structure near the Proton Drip-line: A Search for Excited States in 62Ge

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Dalia Farghaly; [2022]
    Keywords : nuclear physics; nuclear structure; proton drip-line; excited states; germanium; fusion-evaporation reaction; experimental nuclear physics; gamma sphere; gamma spectroscopy; HPGe detectors; data analysis; Physics and Astronomy;

    Abstract : An experiment to study mirror symmetry in the mass A = 60 region was performed at the Argonne National Laboratory (ANL) in 2020. The fusion-evaporation reaction 40Ca + 24Mg → 64Ge* at a beam energy of 106 MeV was used to populate excited states in 62Ge. READ MORE

  6. 5. Lagrangian Bounding and Heuristics for Bi-Objective Discrete Optimisation

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Ida Åkerholm; [2022]
    Keywords : Lagrangian relaxation; bi-objective optimisation; Pareto frontier; heuristics; discrete optimisation;

    Abstract : For larger instances of multi-objective optimisation problems, the exact Pareto frontier can be both difficult and time-consuming to calculate. There is a wide range of methods to find feasible solutions to such problems, but techniques for finding good optimistic bounds to compare the feasible solutions with are missing. READ MORE
