  1. 1. Active- integrated aperture lens antenna

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jesus Ventas Muñoz de Lucas; [2021]
    Keywords : ;

    Abstract : Luneburg lens antennas are gaining popularity in new communication systems, as increasingly higher frequencies are being used. Broadband fully- metallic implementations of Luneburg lenses, such as Rinehart- Luneburg lenses, constitute simple, cheap and efficient beamformers. READ MORE

  3. 2. Understanding Effects of Isothermal Heat Treatments on Microstructure of LMD-w Titanium Alloy (Ti-6242) : On solution heat treated microstructure

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

    Author : Noomi Linder; [2020]
    Keywords : Heat Treatments Isothermal Titanium Alloy Ti-6242 Ti6242 Ti-6Al-2Sn-4Zr-2Mo GKN;

    Abstract : The use and knowledge of additive manufacturing technologies are rapidly growing. It is crucial to understand the processing-structure-property relationship, which is highly discussed when trying to understand the science of a material. One commonly used material in aerospace applications is titanium alloy, lately Ti-6Al-2Sn-4Zr-2Mo (Ti-6242). READ MORE

  4. 3. Assessment of static performance of LKAB´s welded mesh : Laboratory testing and analysis

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Fredrik Eriksson; [2020]
    Keywords : ;

    Abstract : Surface support is an areal support, which is installed on rock excavation surface to prevent bulking of rock mass and retain loose rock fragments. Welded wire mesh is one type of surface support. Literature study indicates that there is a wide range of testing methods on mesh. READ MORE

  5. 4. Evaluation of material properties after laser welding on ductile cast iron

    University essay from KTH/Materialvetenskap

    Author : Olivia Taivalkoski; [2019]
    Keywords : Laser welding; ductile cast iron;

    Abstract : Scania wants to lower the weight of their trucks, including the goal to reduce the carbon dioxide emissions, and one way to do that is to use laser welding instead of fastenings.This bachelor thesis work is about laser welding of ductile cast iron, or spheroidal graphite cast iron or nodular cast iron, to QT-steels and case hardening steel and evaluation of the mechanical properties of the weld.

  6. 5. Simulating Quantum Cascade Lasers with the Position and Energy Resolving Lindblad approach

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Maitane Muñoz Basagoiti; [2019]
    Keywords : quantum cascade lasers; quantum transport; simulations; electron transport; Physics and Astronomy;

    Abstract : Over the past two decades, Quantum Cascade Lasers (QCLs) have become an increasingly popular source for mid-infrared and terahertz radiation. Nowadays, their experimental development progresses fast with the aid of computer simulations. These reproduce carrier dynamics in the gain medium of the laser based on different transport models.
