  1. 1. The Automorphism Groups on the Complex Plane

    Kandidat-uppsats, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Aron Persson; [2017]
    Nyckelord :;

    Sammanfattning : The automorphism groups in the complex plane are defined, and we prove that they satisfy the group axioms. The automorphism group is derived for some domains. LÄS MER

  2. 2. Förbränning av biogas/metan i en EcoMarathonmotor

    Kandidat-uppsats, Chalmers tekniska högskola/Institutionen för tillämpad mekanik

    Författare :Dan Andersson; Felix Eriksson; Henrik Karlsson; Niklas Axelsson; Björn Steinwall Jivenberg; Anton Stenstrand; [2016]
    Nyckelord :;

    Sammanfattning : This report is about the process of converting a petrol-fuelled Honda GX35 engine to runon methane gas. The future goal is to use the engine in the engineering competition ShellEco-marathon, where the aim is to drive a vehicle as far as possible with a set amount offuel. LÄS MER

  3. 3. Cauchy Integrals Method in the Study of Perturbations of Operators

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Johan Balkare; [2016]
    Nyckelord :;

    Sammanfattning : We show that functions which are analytic on the open unit disc and fulfil the Hölder condition of order r  there, where r lies in the interval (0,1), are operator Hölder of order r on the set of all linear contractions on a Hilbert space. Further, it is known that analytic Lipschitz functions on the unit disc need not be operator Lipschitz. LÄS MER

  4. 4. Developement of a portable β-­‐ spectrometer for in situ measurements of Sr-­‐90 and Y-­‐90 using a plastic scintillator and a silicon photomultipler (SiPM).

    Master-uppsats, Lunds universitet/Medicinsk strålningsfysik, Lund; Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Daniel Krona; [2015]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : In the event of a nuclear weapon detonation or a power plant accident radionuclides will deposit on the ground. It is then important to identify and quantify the radionuclides to obtain information necessary for radiation protection efforts like relocation and decontamination. LÄS MER

  5. 5. Some properties of Bessel functions with applications to Neumann eigenvalues in the unit disc

    Kandidat-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Författare :Ashu Mathias Ashu; [2013]
    Nyckelord :Bessel functions; Neumann eigenvalues; Bourget s hypothesis; unit disc; standing water waves; Mathematics and Statistics;

    Sammanfattning : A study is made of the multiplicities of the eigenvalues of the Laplace operator in the unit disc with Neumann boundary conditions. Our result is that all eigenvalues are simple or double, a result which is well-known if one instead considers Dirichlet boundary conditions. The result is proved by using some properties of Bessel functions. LÄS MER
