  1. 1. Inverse Uncertainty Quantification for Sounding Rocket Dispersion

    University essay from KTH/Matematik (Avd.)

    Author : Tove Ågren; [2022]
    Keywords : Uncertainty quantification; Bayesian inference; Rocket dispersion; Neural networks; Markov Chain Monte Carlo.; Osäkerhetskvantifiering; Bayesiansk inferens; Raketspridning; Neurala nätverk; Markovkedje-Monte Carlo;

    Abstract : Sounding rocket impact points are subject to dispersion due to uncertainties in simulation model parameters and perturbations of the rocket trajectory during flight. Estimating the area of dispersion assumes that associated model uncertainties and magnitude of perturbations have already been inferred. READ MORE

  3. 2. A Cost Breakdown and Production Uncertainty Analysis of Additive Manufacturing : A Study of Low-Volume Components Produced with Selective Laser Melting

    University essay from Blekinge Tekniska Högskola/Institutionen för industriell ekonomi

    Author : Jonas Barsing; [2018]
    Keywords : Production uncertainty; Product cost; Additive manufacturing; Cost estimation; AM; Produktionsosäkerheter; produktkostnad; additiv tillverkning; kostnadsuppskattning; AT;

    Abstract : Background: Additive manufacturing has recently gained cogency as a final part manufacturing technique. The method uses a layer-upon-layer technique to build three-dimensional objects. This technique has many advantages creating new opportunities regarding production. READ MORE

  4. 3. Uncertainty Quantification of a Large 1-D Dynamic Aircraft System Simulation Model

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

    Author : Johan Karlén; [2015]
    Keywords : Uncertainty; Quantification; Dynamic; Modelica; Dymola;

    Abstract : A 1-D dynamic simulation model of a new cooling system for the upcoming Gripen E aircraft has been developed in the Modelica-based tool Dymola in order to examine the cooling performance. These types of low-dimensioned simulation models, which generally are described by ordinary differential equations or differential-algebraic equations, are often used to describe entire fluid systems.

  5. 4. Poetry is for everyone : A comparative analysis of the cut-up technique, Magnetic poetry and the casual word game Words of Oz

    University essay from Uppsala universitet/Institutionen för speldesign

    Author : Karin Ryding; [2014]
    Keywords : Cut-up technique; Dadaism; Surrealism; word games; transformative play; critical play; poetry games; Magnetic Poetry; Words of Oz;

    Abstract : Language is a system that fundamentally influences us as human beings. There are numerous schools of thought critiquing our use of language and celebrating attempts to break free of the control it has over our lives. READ MORE

  6. 5. Application of CFD to Safety and Thermal-Hydraulic Analysis of Lead-Cooled Systems

    University essay from KTH/Fysik

    Author : Marti Jeltsov; [2011]
    Keywords : Coupled Codes; Verification Validation; CFD; System Thermal-Hydraulics; Lead Cooled sys-;

    Abstract : Computational Fluid Dynamics (CFD) is increasingly being used in nuclear reactor safety analysis as a tool that enables safety related physical phenomena occurring in the reactor coolant system to be described in more detail and accuracy. Validation is a necessary step in improving predictive capability of a computationa code or coupled computational codes. READ MORE
