  1. 21. Understanding the effect of temperature and time on Gamma prime coarsening for Nickel-base superalloy Haynes 282

    University essay from KTH/Materialvetenskap

    Author : Kevin Vattappara; [2019]
    Keywords : Haynes 282; gamma prime 𝛾′ ; Arc-heat treatment; COMSOL modelling; isothermal transformation; coarsening; Thermo-Calc simulations;

    Abstract : Haynes 282 is a gamma prime (𝛾′)-strengthened nickel base superalloy developed in 2005, exhibiting a good combination of high temperature properties and fabricability. Microstructural features such as 𝛾′ and carbides play an important role in deriving the mechanical properties of the alloy during heat treatment. READ MORE

  3. 22. Portfolio Optimization with Catastrophe Bonds

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Tianfang Zhang; [2019]
    Keywords : Catastrophe bonds; Poisson processes; Portfolio theory; Value-at-risk; Conditional value-at-risk;

    Abstract : This thesis investigates properties of the returns of catastrophe bonds and their risk diversification potential in portfolios. Ideas from existing literature, such as modeling the evolution of the outstanding principal as a compound Poisson process, are extended to take into account the times of occurrence of the loss events, which are important for the returns of catastrophe bonds with certain types of payment structure.

  4. 23. Macroprudential regulation of borrowing standards: a comparative analysis of loan-to-value and loan-to-income policies.

    University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi; Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Sante Carbone; Oona Hakala; [2019]
    Keywords : Consumer Debt; Crisis; Housing; Housing Finance; Bayesian;

    Abstract : Starting from the Two-Agents New-Keynesian DSGE framework presented by Iacoviello and Neri (2010), we re-write the model allowing for a loan-to-income (LTI) constraint in place of a loan-to-value (LTV) constraint. We derive a balanced growth path equilibrium for our model and compare steady-state results as well as dynamic responses to a rich set of shocks between the two macroprudential regulations.

  5. 24. Machine learning multicriteria optimization in radiation therapy treatment planning

    University essay from KTH/Matematisk statistik

    Author : Tianfang Zhang; [2019]
    Keywords : Radiation therapy; automated planning; machine learning; multicriteria optimization; dose mimicking; dose--volume criteria; Gaussian mixture model; expectation--maximization; exponential tilting; Strålterapi; automatisk planering; maskininlärning; flermålsoptimering; dosåterskapande; dos--volym-kriterier; gaussisk blandningsmodell; förväntning--maximering; exponentiell lutning;

    Abstract : In radiation therapy treatment planning, recent works have used machine learning based on historically delivered plans to automate the process of producing clinically acceptable plans. Compared to traditional approaches such as repeated weighted-sum optimization or multicriteria optimization (MCO), automated planning methods have, in general, the benefits of low computational times and minimal user interaction, but on the other hand lack the flexibility associated with general-purpose frameworks such as MCO.

  6. 25. Is operating performance driving stock performance? - A study on Swedish listed real estate companies

    University essay from Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

    Author : Oscar Lundqvist; [2019]
    Keywords : Value relevance; Real estate; Operating performance; IFRS; IAS 40;

    Abstract : As suggested by the title, the purpose of this study is to analyse the relationship between stock performance and operating performance using a sample of Swedish listed real estate companies. In recent years, Swedish real estate companies have experienced positive development profits and stock prices, driven by favourable development in real estate prices. READ MORE
