  1. 1. 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

  3. 2. Regional Risk Sharing Among Swedish Municipalities

    University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Author : Rasmus Hegefors; Henrik Hällerfors; [2021]
    Keywords : risk sharing; regional redistribution and stabilization; fiscal equalisation; local government;

    Abstract : We use panel data to analyse long-run and short-run risk sharing among Swedish municipalities in terms of municipal-level personal incomes during the period 2000-2018 and local government finances during 2005-2018. We find that long-run redistribution of personal incomes amounts to 44 percent and short-run stabilisation to 39 percent. READ MORE

  4. 3. Comparison of mesophilic and thermophilic anaerobic sludge digestion at Hammarby Sjöstadsverk MBR pilot plant for wastewater treatment

    University essay from SLU/Department of Molecular Sciences

    Author : Jessica Sellin; [2021]
    Keywords : Anaerobic digestion; sludge; wastewater treatment; thermophilic; mesophilic; stress test;

    Abstract : Anaerobic digestion is a commonly used method for stabilisation of sewage sludge and production of biogas at municipal wastewater treatment plants (WWTPs). The hydraulic retention time for sludge in the digestion reactors is about 16 days at Henriksdal WWTP in Stockholm. READ MORE

  5. 4. Stabilisation of arsenic in contaminated soil using iron distributed by electricity

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

    Author : Kajsa Engström; [2021]
    Keywords : Chemical stabilisation; soil remediation; contaminated soil; in situ pilot scale; sacrificial iron;

    Abstract : In Boden, northern part of Sweden, there is a site called Solgårdarna which has been used for wood impregnation. The activities on the site have led to soil contamination with chrome (Cr), copper (Cu) and arsenic (As), where the arsenic contamination is the most problematic. READ MORE

  6. 5. 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
