  1. 1. Moderling Acoustic Transmission in Towed Array Sonars : Computations of the coupled acoustic and elastic wave equations

    University essay from KTH/Matematik (Avd.)

    Author : Bill Claesson; [2023]
    Keywords : ;

    Abstract : This thesis presents a method of solving the Helmholtz equation coupled with the Navier-Cauchy equation over a cross section of a Towed Array Sonar (TAS) modeled as a simplified cylindrical shell. The purpose of solving these equations is to estimate the transfer function of the pressure between the outside boundary and a position inside the TAS. READ MORE

  3. 2. Orsaker till dystoki hos marsvin i Sverige

    University essay from SLU/Dept. of Clinical Sciences

    Author : Johanna Cavell; [2022]
    Keywords : förlossning; förlossningsproblem; dräktighet; felläge; foster; bäcken;

    Abstract : Marsvin är populära sällskapsdjur som tros ha blivit domesticerade redan på 500–1000-talet. Marsvin blir könsmogna tidigt, honorna vid cirka två månaders ålder och hanarna vid cirka tre månaders ålder. Marsvinshonor är polyöstrala med en cykel på 15–17 dygn där östrus varar i 6–11 timmar.

  4. 3. Study of Corner and Bathtub Attachments with Respect to Static Sizing

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Linus Malm; [2022]
    Keywords : Applied Mechanics; Solid Mechanics; FEM; Static Strength; Abaqus; Fittings; Failure Modes;

    Abstract : This master thesis studied the possibilities of implementing new handbook methodologies for sizing of corner and bathtub attachments with respect to static strength.  Parametric studies of corner and bathtub attachments were performed in order to examine the effect of boundary conditions and vital dimensions with respect to static strength.

  5. 4. Modeling of Low-Energy Neutron Scattering in Liquid Hydrogen Using NCrystal

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB; Lunds universitet/Kärnfysik

    Author : Tim Günter; [2022]
    Keywords : ESS; European Spallation Source; neutron; scattering; moderator; liquid hydrogen; modeling; ncrystal; njoy; Physics and Astronomy;

    Abstract : The European Spallation Source ESS, under construction in Lund, Sweden, aims to produce high-brightness and intensity neutrons for a multitude of experiments upon completion. An efficient production of neutrons requires elaborate understanding of the moderation process which slows the neutrons from relativistic speed to a kinetic energy of meV. READ MORE

  6. 5. Low-Temperature Thermal Control System for an Environmental Chamber

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Aleksis Pauls Lindemanis; [2022]
    Keywords : Space simulator; environmental chamber; thermal control design; thermal conductivity in bolted joints; thermal simulations; Mars climate; Carbon dioxide sublimation and deposition;

    Abstract : In spite of significant reduction of cost associated with launching a spacecraft, launching deep space exploratory missions are yet to be accessible to most universities and researchers. A solution to testing scientific hypotheses and verifying technologies for space is the use of environmental chambers, also know as space simulators, - vacuum chambers, which replicate the space environment.
