  1. 1. A Root Sum of Squares approach for determining uncertainties in three different ways of characterizing a surface temperature for a Hot Box Setup : With added U-value calculations and incorporated uncertainties

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Tobias Wikman; [2022]
    Keywords : ;

    Abstract : The aim of this Master Thesis is to conduct an uncertainty analysis of three ways of characterizing a surface temperature of a Hot Box Setup (direct measurement, analytically calculatedand simulated). The purpose was to to provide insight into uncertainty analysis within Hot Box Setups. READ MORE

  2. 2. Imputation and Generation of Multidimensional Market Data

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Tobias Wall; Jacob Titus; [2021]
    Keywords : Time Series Imputation; Financial Time Series; Machine Learning; Deep Learning; Value at Risk; Expected Shortfall; Imputering av Tidsserier; Finansiella Tidsserier; Maskininlärning; Djupinlärning; Value at Risk; Expected Shortfall;

    Abstract : Market risk is one of the most prevailing risks to which financial institutions are exposed. The most popular approach in quantifying market risk is through Value at Risk. Organisations and regulators often require a long historical horizon of the affecting financial variables to estimate the risk exposures. READ MORE

  3. 3. A Comparison of Path Planning Algorithms for Robotic Vacuum Cleaners

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

    Author : Jacob Sörme; Tobias Edwards; [2018]
    Keywords : ;

    Abstract : Household robotics is on the rise with robotic vacuum cleaners taking the lead. One of the challenges in creating great robotic vacuum cleaners is path planning for coverage of the room. For instance, the robot might not know how the environment looks, or where in the room the robot is. READ MORE

  4. 4. Conceptual sandwich-sandwich-steel joint design for lightweight rail vehicle

    University essay from KTH/Lättkonstruktioner

    Author : Tobias Magnusson; [2014]
    Keywords : ;

    Abstract : In order to find a feasible solution for a joining method of a sandwich side-wall, a sandwichfloor and a steel underbody of a railway vehicle, conceptual joint designs have been devel- oped by using structural optimization software.  It is shown that the joints are capable of carrying the loads assumed to act on the structure but that  several improvements to theanalysis needs to be done to assure a safe design.

  5. 5. Building and Evaluating a 3D Scanning System for Measurementsand Estimation of Antennas and Propagation Channels

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Erik Johannes Aagaard Fransson; Tobias Wall-Horgen; [2012]
    Keywords : 3D field scanner; radio propagation channel; virtual array; MIMO; Angle-of-Arrival; regularization; inverse problem; L-curve; truncated singular value decompositions; successive interference cancellation; horn antenna; phase center.;

    Abstract : Wireless communications rely, among other things, on theunderstanding of the properties of the radio propagationchannel, the antennas and their interplay. Adequate measurementsare required to verify theoretical models and togain knowledge of the channel behavior and antenna performance. READ MORE
