  1. 11. Embedded eigenvalues for asymptotically periodic ODE Systems

    University essay from Lunds universitet/Matematik LTH

    Author : Wilhelm Treschow; [2022]
    Keywords : embedded eigenvalue perturbation theory ODE theory; Mathematics and Statistics;

    Abstract : In this thesis we investigate the persistance of embedded eigenvalues under perturbations of a certain self-adjoint Schrödinger-type differential operator in L^2(\mathbb{R},\mathbb{R}^n), with an asymptotically periodic potential. The studied perturbations are small and belong to a certain Banach space with a specified decay rate, in particular, a weighted space of continuous matrix valued functions. READ MORE

  3. 12. CONTROL STRATEGY AND MODELING FOR ENGINE OIL SYSTEM

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

    Author : Dalibor Colic; Jakob Norin; [2021]
    Keywords : ;

    Abstract : The power of an engine is not only used to drive the mechanical equipment connected to the engine, but also parts of the engine itself. One of these parts is the oil pump. The minimum needed oil pressure, produced by the pump, varies during the operational run of the engine. READ MORE

  4. 13. Pricing Complex derivatives under the Heston model

    University essay from KTH/Matematik (Avd.)

    Author : Omar Naim; [2021]
    Keywords : Stochastic volatility Model; Heston Model; Calibration; Financial derivatives; Stokastisk volatilitetsmodell; Heston modell; kalibrering; finansiella derivat;

    Abstract : The calibration of model parameters is a crucial step in the process of valuation of complex derivatives. It consists of choosing the model parameters that correspond to the implied market data especially the call and put prices. READ MORE

  5. 14. Modeling The Temperature of a Calorimeter at Clab : Considering a Thermodynamic Model of The Temperature Evolution of The Calorimeter System 251

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Johannes Ekman; [2021]
    Keywords : calorimetry; calorimeter; System 251; temperature evolution; spent nuclear fuel; SNF; MATLAB; SERPENT2; Clab; nuclear decay heat; calibration measurements; thermodynamic model; gamma escape fraction; mass correction; calibration measurements; electric heater; three component system; system of ordinary differential equations; eigenvalues; eigenvalue estimation; temperature increase method; polynomial approximation of mass correction; sensitivity of mass correction; calorimeter heat capacity; mass correction uncertainty; calorimeter calibration curve; monoenergetic gamma spectrum; curve fitting of temperature as function of time;

    Abstract : It is important to know the heat generated due to nuclear decay in the final repository for spent nuclear fuel. In Sweden, the heating powers generated in spent nuclear fuels are currently measured in the calorimeter System 251 at the Clab facility, Oskarshamn. READ MORE

  6. 15. Anomaly Detection in Networks using Autoencoder and Unsupervised Learning Methods

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

    Author : Simon Azmoudeh Fard; [2021]
    Keywords : ;

    Abstract : The increasing popularity of networking devices at workplaces leads to an exponential increase in the frequency of network attacks. This leads to having protected networks being more and more important. Because of the increase in network activity workplaces have started to leave anomaly detection in the hands of artificial intelligence. READ MORE
