1. 1. Distortion and attenuation free gain-assisted Superluminal Propagtion in a Rare-Earth Doped Crystal

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Antonius Johannes Renders; [2023]
   Keywords : Fast Light; Superluminal Propagation; Negative group velocity; Rare earth; Physics and Astronomy;

   Abstract : A light pulse that travels through a narrow spectral window, i.e. a frequency range of low absorption, within a strongly absorbing frequency range will be delayed due to strong dispersion. READ MORE

3. 2. Active stabilisation of a micro-sized fibre cavity using tilt locking to enable quantum operations on single ions

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Jannek Hansen; [2021]
   Keywords : Quantum computation; optical cavity; microcavity; locking; tilt locking; cavity stabilization; Gaussian-Hermitian modes; quantum computer; higher-order transverse modes; Physics and Astronomy;

   Abstract : In this thesis, the tilt locking scheme is applied to create an error signal that monitors length changes in a fibre-based microcavity. To find a robust and precise locking technique is an essential step towards quantum operations on single rare-earth ions doped in microcrystals. Quantum computing and information is a frontier of modern physics. READ MORE

4. 3. What motivates countries’ decisions to contribute to peacekeeping? : The case of Sweden

   University essay from Linnéuniversitetet/Institutionen för samhällsstudier (SS)

   Author : Lovisa Sand; [2020]
   Keywords : Peacekeeping; MINUSMA; Sweden; decision-making; rational choice.;

   Abstract : Following the mid 1990s, a drop in Swedish contributions to UN led peacekeeping have been evident and EU and NATO led operations have taken preference. However, in 2013 Sweden invested in a substantial troop contribution to a UN led peacekeeping operation in Mali. READ MORE

5. 4. Robust and Agile Attitude Control for Triple CubeSat Eye-Sat

   University essay from KTH/Rymdteknik

   Author : Benjamin Charbaut; [2018]
   Keywords : ;

   Abstract : Eye-Sat is a student-designed 3U-CubeSat, to be launched to a sun-synchronous orbit from where it will map the zodiacal light, a faint glare caused by the reflection of Sun on interplanetary dust. Such mission requires an accurate 3-axis attitude control, for which Eye-Sat is equipped with reactions wheels, magnetorquers, magnetometers and a star tracker. READ MORE

6. 5. Lunar Light House

   University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö

   Author : Monika Lipinska; [2018]
   Keywords : architecture; space; space architecture; moon; lunar; light house; cellulose; nano-cellulose; moon base; lunar outpost; Arts and Architecture;

   Abstract : The Lunar Light House project was developed to provide a novel system of protection against cosmic radiation specifically for a surface Lunar base. It’s main target was to find a technical solution which would allow for more freedom in shaping the base structure and also potentially for introducing natural sun light. READ MORE
