  1. 21. Doping Layers in Quantum Cascade Lasers: A study in doping density, position and migration effects

    University essay from Lunds universitet/Matematisk fysik

    Author : Josefin Reftlér; [2022]
    Keywords : Physics and Astronomy;

    Abstract : Quantum Cascade Lasers (QCLs) consist of several semiconductor materi- als sandwiched together. The QCL achieves stimulated emission in the mid-IR (m-IR) to the THz region of the electromagnetic spectrum by inter-subband transitions. These parts of the electromagnetic spectrum are hard to lase in with conventional means. READ MORE

  3. 22. Drivers of decomposition across Sphagnum bog margins

    University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Author : Emil Nordström; [2022]
    Keywords : Peatlands; tea bag index; edge effects; carbon storage; carbon sequestration; waterlogging; Torvmark; kanteffekter; kollagring; koldioxidbindning;

    Abstract : Peatlands provide multiple ecosystem services, including extensive carbon sequestration and storage, yet many peatlands have been degraded or destroyed. Peatlands carbon storage capacity is connected to inherently low decomposition rates, causing the build-up of organic matter.

  4. 23. Predicting Quality of Experience from Performance Indicators : Modelling aggregated user survey responses based on telecommunications networks performance indicators

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

    Author : Christian Vestergaard; [2022]
    Keywords : Quality of Experience; Telecommunication; Regression; Long Short Term Memmory; Clustering; K-means; Gaussian Mixture Models; Användarupplevelse; Telekommunikation; Regression; Long Short Term Memmory; Klusteranalys; K-means; Gaussian Mixture Models;

    Abstract : As user experience can be a competitive edge, it lies in the interest of businesses to be aware of how users perceive the services they provide. For telecommunications operators, how network performance influences user experience is critical. To attain this knowledge, one can survey users. READ MORE

  5. 24. Variations in depositional environments of the Paleogene Firkanten Formation across Adventdalen, from Operafjellet to Breinosa

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Anna Stella Guðmundsdóttir; [2021-03-18]
    Keywords : ;

    Abstract : The lowermost Paleogene clastic infill of the Central Spitsbergen Tertiary Basin, the coal bearing Firkanten Formation, has been the subject of study for researchers in the past but little focus has been on the northeast edge of the basin until now. Due to the economic potential of the coal seams in the formation, the Norwegian mining company, Store Norske Spitsbergen Grubekompani (SNSG), has for several years conducted core drilling in key locations in basin, and for decades, they have given an access to their core material to researchers.

  6. 25. Woodland key habitats for functional forest landscape green infrastructure in the Swedish mountain region

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Britta Sterner; [2021]
    Keywords : woodland key habitat; green infrastructure; connectivity; forest biodiversity; NW Sweden;

    Abstract : The intact forest landscapes along the Scandinavian Mountain range are of very high conservational value both nationally and internationally, due to their intact characteristics and biodiversity. The high nature conservation values have remained as a result of restricted forest clear-cutting above the so-called mountain forest border (MFB). READ MORE
