  1. 1. Implementation and characterization of Silicon detectors for studies on neutron-induced nuclear reactions

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Leo Lehtilä; [2019]
    Keywords : Silicon detector; Silicon telescope; Ultra-thin silicon detector; Energy resolution; Radioactive source; Am-241; Cf-252; Fission Fragments; Alpha Particles;

    Abstract : Energy resolution characteristics of silicon surface barrier detector signals amplified by different preamplifiers and spectroscopic amplifiers have been studied. The characterization has been done using alpha particles from an 241Am source and spontaneous fission fragments from two Cf sources. READ MORE

  2. 2. Inductively-Coupled Plasma Etching for Nanoimprint Si-masters

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Oskar Boström; [2019]
    Keywords : NIL; Semiconductor; EBL; SEM; ICP-RIE; Fluorine Etching; Physics; Technology and Engineering;

    Abstract : In the last decades, engineers have been pushing semiconductor technology towards fabricating ever smaller devices, and will eventually pass the lower limit of currently commonplace optical lithographic techniques. New techniques have been developed, such as nanoimprint lithography. READ MORE

  3. 3. Assessing evolution of ice caps in Suðurland, Iceland, in years 1986 - 2014, using multispectral satellite imagery

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alicja Miodonska; [2019]
    Keywords : remote sensing; multispectral satellite imagery; Landsat; Iceland; glaciers; ice caps; Geography; GIS; Earth and Environmental Sciences;

    Abstract : The study focuses on the application of multispectral satellite imageries in glaciological studies. It aims to assess how the Icelandic glaciers have evolved over the last decades (from the 1980s to 2014). The study area covers Mýrdalsjökull and Eyjafjallajökull ice caps located in Suðurland, Iceland. READ MORE

  4. 4. Mechanical properties of SiC nanowires with polytypes

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Anders Vesti; [2019]
    Keywords : atomistic modeling; nanowires; molecular dynamics; simulation; SiC; silicon carbide; fracture behavior; nanomechanics; Physics and Astronomy;

    Abstract : In this report, we model the mechanical properties and fracture behavior of SiC nanowires with different polytypes using Molecular Dynamics (MD) simulations. The mechanical properties investigated are the Young’s modulus, the maximum tensile stress and the fracture strain. The three polytype tested are SiC (3C), (2H) and (4H). READ MORE

  5. 5. Full Cycle Cylinder State Estimation in DI Engines with VVA

    University essay from Linköpings universitet/Fordonssystem

    Author : Linus Johansson; [2019]
    Keywords : VVT; Combustion engine; Thermodynamics; CRB;

    Abstract : Tougher legal demands on pollutions require a better developed understanding of the processes that take place in the cylinder. The thesis contributes with a cylinder model that uses the same set of equations for intake, compression,expansion/combustion and exhaust. READ MORE
