  1. 1. Implementation of Reaction Kinetics into Reactor Model Followed by Validation of the Reactor Model

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Rebecka Svensson; [2021]
    Keywords : Modeling; Reaction kinetics; Chemical Engineering; Technology and Engineering;

    Abstract : This master thesis project was performed in collaboration with Johnson Matthey. Johnson Matthey is a worldwide company working with sustainable technologies. The site in Perstorp, where this work was performed, focus on formaldehyde production. In order to continuously improve chemical processes, simulation and modeling are advantageous tools. READ MORE

  3. 2. Wiener-Lévy Theorem : Simple proof of Wiener's lemma and Wiener-Lévy theorem

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Jose Eduardo Vasquez; [2021]
    Keywords : Wiener-Lévy Theorem; Wiener s Lemma; Fourier series; Complex analysis;

    Abstract : The purpose of this thesis is to formulate and proof some theorems about convergences of Fourier series. In essence, we shall formulate and proof Wiener's lemma and Wiener-Lévy theorem which give us weaker conditions for absolute convergence of Fourier series. READ MORE

  4. 3. The Henstock–Kurzweil Integral

    University essay from Linköpings universitet/Matematik och tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Manolis David; [2020]
    Keywords : Henstock–Kurzweil integral; generalized Riemann integral; gauge integral; Denjoy–Perron integral; narrow Denjoy integral; Perron integral; non-absolute integration; Lebesgue outer measure; absolute integrability; fundamental theorem of calculus; convergence theorems; single variable calculus;

    Abstract : Since the introduction of the Riemann integral in the middle of the nineteenth century, integration theory has been subject to significant breakthroughs on a relatively frequent basis. We have now reached a point where integration theory has been thoroughly researched to a point where one has to delve quite deep into a particular subject in order to encounter open conjectures.

  5. 4. On the Properties of Wiener-Lévy Functions

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Albin Petersson; [2019]
    Keywords : ;

    Abstract : This thesis concerns the Wiener algebra of periodic functions with absolutely convergent Fourier series, and the "Wiener-Lévy functions", meaning functions that preserve absolute convergence of Fourier series under composition. Results regarding the properties of functions in the Wiener algebra are established, as well as properties of Wiener-Lévy functions. READ MORE

  6. 5. An Introduction to Dirichlet Series

    University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Eda Dagasan; [2018]
    Keywords : Mathematics; Dirichlet Series; Riemann Zeta Function; Complex Analysis; Bohr s Theorem; Mathematics and Statistics;

    Abstract : We establish the central convergence properties of ordinary Dirichlet series, including the classical result by Bohr, providing uniform convergence of the series where it has a bounded analytic continuation. We also derive a lower bound for the supremum of Dirichlet polynomials using Kronecker's theorem, of which we see one proof. READ MORE
