  1. 1. A sensitivity analysis of the Winter-Kennedy method

    Författare :Binaya Baidar; Michel J. Cervantes; Mikael Sendelius; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydropower; discharge; Winter-Kennedy; CFD; Sensitivity; Strömningslära; Fluid Mechanics;

    Sammanfattning : Hydropower is among the lowest-cost electrical energy sources due to its long lifespan and lower operation and maintenance cost. The hydro-mechanical components of hydropower plants generally last about four to five decades, then they are either overhauled or replaced. LÄS MER

  4. 3. The Skorohod problem and weak approximation of stochastic differential equations in time-dependent domains

    Författare :Thomas Önskog; Kaj Nyström; Leif Persson; Johan Tysk; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Skorohod problem; weak approximation; time-dependent domain; stochastic differential equations; parabolic partial differential equations; oblique reflection; stopped diffusions; Euler scheme; adaptive methods; sensitivity analysis; financial derivatives; Greeks ; MATHEMATICS; MATEMATIK; Mathematics; matematik;

    Sammanfattning : This thesis consists of a summary and four scientific articles. All four articles consider various aspects of stochastic differential equations and the purpose of the summary is to provide an introduction to this subject and to supply the notions required in order to fully understand the articles.

  5. 4. Language-Based Differential Privacy with Accuracy Estimations and Sensitivity Analyses

    Författare :Elisabet Lobo Vesga; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; haskell; accuracy; parametricity; Program reasoning; Functional Programming; concentration bounds; differential privacy;

    Sammanfattning : This thesis focuses on the development of programming frameworks to enforce, by construction, desirable properties of software systems. Particularly, we are interested in enforcing differential privacy -- a mathematical notion of data privacy -- while statically reasoning about the accuracy of computations, along with deriving the sensitivity of arbitrary functions to further strengthen the expressiveness of these systems.

  7. 5. Convergence and stability analysis of stochastic optimization algorithms

    Författare :Måns Williamson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; numerical analysis; optimization; stochastic optimization; machine learning;

    Sammanfattning : This thesis is concerned with stochastic optimization methods. The pioneering work in the field is the article “A stochastic approximation algorithm” by Robbins and Monro [1], in which they proposed the stochastic gradient descent; a stochastic version of the classical gradient descent algorithm.
