  1. 1. Peace from the barrel of a gun. : The effect of NATO and UN peace enforcement on war intensity.

    Master-uppsats, Uppsala universitet/Institutionen för freds- och konfliktforskning

    Författare :Robin Sällström; [2023]
    Nyckelord :Peacekeeping; peace enforcement; NATO; UN; war intensity.;

    Sammanfattning : Since 1991, NATO has played a prominent role in peacekeeping and peace enforcement in the Balkans and Afghanistan. Despite NATO’s role in peacekeeping, there is little literature that compares the efficacy of NATO and UN peace enforcement operations. LÄS MER

  3. 2. Optimization of DNA trace collection from firearms and effects of different gun handling scenarios

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Lisa Lindahl; [2022]
    Nyckelord :Forensic; DNA; DNA-recovery; Optimization of DNA-recovery; DNA-amount; firearms; guns; swabs; crimes; applied microbiology; Technology and Engineering;

    Sammanfattning : More than 500 people die every day from gun violence worldwide. DNA traces may enable the identification of the shooter, but there is limited knowledge concerning where on firearms DNA can be found and how it got there. This project aimed to answer these questions as well as how the swab types and addition of detergents affect the DNA recovery. LÄS MER

  4. 3. Modelling of electromechanical motors for turret and barrel control in main battle tanks

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Arvid Carlstedt; [2021]
    Nyckelord :Mechanics; Mechatronics; Vehicle Technology; Mekanik; Mekatronik; Fordonsteknik;

    Sammanfattning : In this master thesis the dynamics of a modern main battle tank's turret traverse and gun elevation have been modelled. The models of dynamic motion have been coupled to two different types of electric motors, namely a direct-current motor and an induction motor. LÄS MER

  5. 4. Lättgaskanonens innerballistik : Teori, simulering och parameterstudie

    Master-uppsats, KTH/Maskinkonstruktion (Avd.)

    Författare :Viktor Landemoo; [2021]
    Nyckelord :Gas dynamics; Internal ballistics; Light gas gun; Gasdynamik; Innerballistik; Lättgaskanon;

    Sammanfattning : En lättgaskanon är en typ av kanon som används vid experiment där mycket snabba förlopp är av intresse, till exempel hypersonisk strömning och höghastighetskollisioner. Kanontypen når betydligt högre hastigheter än en konventionell kanon då projektilen accelereras genom eldröret av en gas med låg molekylmassa som vätgas eller helium istället för krutgaser. LÄS MER

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

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Martin Perkovic; [2020]
    Nyckelord :Wear; erosion; sliding wear; gun barrel; characterisation;

    Sammanfattning : 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. LÄS MER
