1. Automatiserade sorteringsprocesser för textilavfall : En studie av återvinningseffektivitet och resursflöden
Kandidat-uppsats, KTH/ProduktionsutvecklingSammanfattning : Textilkonsumtion i världen har ökat drastiskt under de senaste decennierna, vilket också syns i övergången till att fast fashion nu dominerar textilindustrin. Även i Sverige har konsumtionen ökat, vilket bidrar till att textilindustrin skapar allvarliga följder för miljön. LÄS MER
2. Laboratory starlight simulator for future space-based heterodyne interferometry
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : In astronomy, interferometry by ground-based telescopes offers the greatest angular resolution. However, the Earth´s atmosphere distorts the incident wavefront from a celestial object, leading to blurring and signal loss. It also restricts the transmission of specific wavelengths within the electromagnetic spectrum. LÄS MER
3. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. LÄS MER
4. A Positioning System for Landing a UAV on a UGV in a GNSS-Denied Scenario
Master-uppsats, Linköpings universitet/Institutionen för systemteknikSammanfattning : A system of an unmanned aerial vehicle (UAV) collaborating with an unmanned ground vehicle (UGV) for use in for example surveillance, reconnaissance, transport and target acquisition is studied. The project investigates the problem of estimating the relative position, velocity and orientation between the UAV and the UGV required to autonomously land the UAV on the UGV during movement.

5. Photo-physical properties of up-converting NaYF4:Yb-Er,Yb-Mn nanocrystals
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Rare earth-doped upconversion nanoparticles can emit light with various wavelength from ultraviolet to infrared when excited by near-infrared light. The superior properties including long luminescence lifetime, narrow emission spectra, low toxicity and high chemical stability makes it a promising optical material in bioimaging and other applications.
