  1. 1. Mapping and characterisation of surface damage and wear mechanisms in gun barrels : Gun barrels exposed to cyclic thermo-mechanical loading

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Martin Perkovic; [2020]
    Keywords : Wear; erosion; sliding wear; gun barrel; characterisation;

    Abstract : Gun barrels are an important component in advanced defence systems. The gun barrels are used for direct and indirect fire and the material of the gun barrel is exposed to great strains and high temperatures. This sets high demands on the material of the gun barrel. During firing the gun barrel can be damaged. READ MORE

  2. 2. Heat Transport in Inhomogeneous Harmonic Chains

    University essay from KTH/Skolan för teknikvetenskap (SCI); KTH/Skolan för teknikvetenskap (SCI)

    Author : Daniel Niemi; Joel Hambraeus; [2020]
    Keywords : ;

    Abstract : It is still to this day a challenge for theoretical physicists to derive Fourier’s law from microscopic models. Motivated by this, we study in this thesis the thermal conduction properties of harmonic chains. READ MORE

  3. 3. Design of a FEEP Thruster for Micro-/Nano-Satellites

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Muhammad Ali Badami; [2019]
    Keywords : FEEP; Cube Satellite; Indium; Slit Emitter;

    Abstract : CubeSat development has seen a rise since the first launch in 2003 due to faster design process and low launch costs. It has played a vital role in providing access to space to small start-ups and academic organizations with low budgets. READ MORE

  4. 4. Capacitance Optimization and Ballistic Modeling of Nanowire Transistors

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Azal Alothmani; [2018]
    Keywords : Nanowire transistor; 1-D MOSFET; RF performance; permittivity; parasitic capacitance; HSQ; COMSOL Multiphysics; Technology and Engineering;

    Abstract : Downscaling of Si-based metal-oxide-semiconductor field-effect transistors (MOSFETs) has contributed to increased microchip device density and to improve the functionality of the electronic circuits. The dimensions of state of art MOSFET is down to a few nanometers. It has been demonstrated that smaller MOSFETs are faster and more energy-efficient. READ MORE

  5. 5. Development of Vessel Phantoms for Ultrasound Methods

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Benjamin Meirza; [2018]
    Keywords : Longitudinal movement of the arterial wall; Vasa vasourom; Micro vessles; SEBS; Ultrasound phantom.; Technology and Engineering;

    Abstract : Phantoms mimicking the specific mechanical and acoustic properties of human tissues are essential in the development and evaluation of novel ultrasound methods. In this work, various ultrasound phantoms are proposed to be used in the development of ultrasound methods to investigate the arterial walls longitudinal movements influence on the vasa vasorum circulation.
