1. 1. A Dual-Lens Approach to Loss Given Default Estimation: Traditional Methods and Variable Analysis

   University essay from KTH/Matematik (Avd.)

   Author : William Jaeckel; Nicolai Versteegh; [2023]
   Keywords : Loss given default; estimering; jämförande studie; variabelanalys; kreditförvaltning; utlåning till små och medelstora företag; riskanalys; Loss given default; estimering; jämförande studie; variabelanalys; kreditförvaltning; utlåning till små och medelstora företag; riskanalys;

   Abstract : This report seeks to thoroughly examine different approaches to estimating Loss Given Default through a comparison of traditional estimation methods, as well as a deeper variable analysis on micro, small, and medium-sized companies using primarily regression decision trees. The comparative study concluded that estimating loss given default depends heavily on business-specific factors and data variety. READ MORE

3. 2. Adjoint-based Formulation for Shape Optimization Problems in Computational Fluid Dynamics

   University essay from KTH/Matematik (Avd.)

   Author : Anton Scotte; [2023]
   Keywords : ;

   Abstract : A continuous adjoint formulation for exterior optimization of Dirichlet data on the boundary for potential flow applications has been developed in this thesis. This has been performed by utilizing boundary integral methods for both the primal problem (Laplace’s equation) and for the corresponding adjoint equation (Poisson’s equation) on the unit disc.

4. 3. Estimating eco-friendly driving behavior in various traffic situations, using machine learning

   University essay from Linköpings universitet/Institutionen för datavetenskap

   Author : Ludvig Fors; [2023]
   Keywords : Machine learning; transformers; neural networks; casual inference; K-Means; driver behavior; fuel consumption;

   Abstract : This thesis investigates how various driver signals, signals that a truck driver can interact with, influences fuel consumption and what are the optimal values of these signals in various traffic conditions. More specifically, the objective is to estimate good driver behavior in various traffic conditions and compare bad driver behavior in similar situations to see how performing a specific driver action, changing a driver signal from the bad driver value to the corresponding good driver value impacts the fuel consumption.

5. 4. Sensorless Control of Synchronous Reluctance Machines and Permanent Magnet Synchronous Machines for Pump Applications

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

   Author : Erik Lindberg; [2023]
   Keywords : Variable speed drives; Sensorless control; Luenberger observer; Synchronous reluctance machine; Permanent magnet synchronous machines; Vector control; Model reference adaptive system; Variabel hastighetsreglering; Sensorlös reglering; Luenberger observatör; Synkron reluktansmaskin; Permanentmagnetmaskin; Vektorreglering; Adaptiv modelreferensreglering;

   Abstract : Energy efficiency in electric machines is both environmentally and economically important. Water pumps with an integrated Variable Frequency Drive (VFD) and a Permanent Magnet Synchronous Machine (PMSM) have challenged the status quo of the Induction Machine (IM) for water pumps.

6. 5. Rotor temperature estimation in Induction Motors with Supervised Machine Learning

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

   Author : Christopher Gauffin; [2023]
   Keywords : Induction motors; Supervised Machine learning; Power converters; Parameter estimation; Embedded systems; Induktionsmotorer; Övervakad maskininlärning; Strömkonverterare; Parameterestimering; Inbyggda system;

   Abstract : The electrification of the automotive industry and artificial intelligence are both growing rapidly and can be greatly beneficial for a more sustainable future when combined. Induction machines exhibit many complex relationships between physical and electromagnetic properties that must be calculated in order to produce the correct quantities of torque and speed commanded by the driver.
