  1. 1. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate

    University essay from KTH/Materialvetenskap

    Author : Hagen Christian Hagens; [2022]
    Keywords : Cored wire injection · light alloy addition · feed rate optimization · inclusions modification · finite difference method;

    Abstract : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. READ MORE

  3. 2. Differential Deep Learning for Pricing Exotic Financial Derivatives

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

    Author : Erik Alexander Aslaksen Jonasson; [2021]
    Keywords : Deep Learning; Exotic Derivatives; Differential Machine Learning;

    Abstract : Calculating the value of a financial derivative is a central problem in quantitative finance. For many exotic derivatives there are no closed-form solutions for present values, instead, computationally expensive Monte Carlo methods are used for valuation. READ MORE

  4. 3. CAE Sun Simulation - Thermo Structural Coupling

    University essay from KTH/Numerisk analys, NA

    Author : Kristin Staffas; [2020]
    Keywords : Applied mathematics; Finite Difference Method; Sun simulation; Virtual customer behaviour; Tillämpad matte; Finita Differensmetoden; Solsimulering; Virtuellt kundbeteende;

    Abstract : Deformation of materials due to heat exposure can be a challenge in vehicle design. Sun exposure and heat build up in the vehicle cabin contribute to accelerated aging of the materials used. To understand how this process affects the durability, numerical simulation is an important tool. READ MORE

  5. 4. Investigation of Hybrid Simulation Methods for Evaluation of EMF Exposure in Close Proximity of 5G Millimeter-Wave Base Stations

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

    Author : David Anguiano Sanjurjo; [2020]
    Keywords : 5G; base station; EMF exposure; hybrid simulation method; millimeter wave;

    Abstract : With the emergence of Fifth Generation (5G) mobile networks, the employment ofhigher frequencies in the millimeter-wave (mmWave) range and the realization of agreat number of beams in 5G radio base stations (RBS) make the electromagnetic (EM)simulation of RBS products very costly in terms of hardware and time requirements.In order to compute the electromagnetic field (EMF) exposure in close proximity of theRBS, more efficient simulation methods are required.
