1. 21. Characterizing optical and electrical properties of monolayer MoS2 by backside absorbing layer microscopy

   Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Nathan Ullberg; [2020]
   Nyckelord :backside absorbing layer microscopy; BALM; monolayer MoS2; TMD; TMDC; 2D materials; nanomaterials; nanotechnology; refractive index; extinction coefficient; absorption coefficient; field-effect transistor; FET; semiconductors; optoelectronics; optics; raw image processing; chemical vapor deposition; CVD; in situ characterization;

   Sammanfattning : Nanomaterials are playing an increasing role in novel technologies, and it is important to develop optical methods to characterize them in situ.  To that end, backside absorbing layer microscopy (BALM) has emerged as a powerful tool, being capable to resolve sub-nanometer height profiles, with video-rate acquisition speeds and a suitable geometry to couple live experiments.

3. 22. Development and testing of algorithms for optimal thruster command distribution during MTG orbital manoeuvres

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Lars Sprengelmeyer; [2020]
   Nyckelord :linear programming algorithms; linear optimization; thruster command distribution; thruster control; Simplex; Karmarkar s method; minimum power controller; minimum flow rate controller; minimum control authority;

   Sammanfattning : An accurate satellite attitude and orbit control is a key factor for a successful mission. It guarantees for example sun acquisition on solar panels, fine pointing for optimal telescope usage or satellite lifting to reach higher orbits, when required. LÄS MER

4. 23. A study of wear and load behaviour on bucket teeth for heavy-duty cable shovels

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Jamal Choudhry; [2020]
   Nyckelord :DEM; FEM; bucket; teeth; cable shovel; wear; Archard s law; LS-DYNA; scan;

   Sammanfattning : Many of today’s engineering advancements rely on minerals such as copper, gold and iron. For this reason, the mining industry plays an important role for the development of society and technological wonders. Mining excavators are commonly used tools for extracting the minerals from the mine. LÄS MER

5. 24. Does a Tailored Nine-week Training Intervention Improve Jump Height, Single-leg Stability, and Whole-body Stability Performance in Young Cross-country Skiers?

   Magister-uppsats, Umeå universitet/Avdelningen för idrottsmedicin

   Författare :Frank Rizzo; [2020]
   Nyckelord :Vertical ground-reaction forces; rate of force development; core stability; full-body test; balance; Olympic winter sport;

   Sammanfattning : The purpose of this study was to investigate if a nine-week training intervention composed of different mobility and stability exercises intending to improve jump height, whole-body stability, and single-leg stability of junior cross-country skiers. It was also of interest to see if the test equipment could determine the study participants' potential risk of injury with a built-in injury predictor measurement, Musculoskeletal Health (MSK).

7. 25. Hur påverkas direktavkastningskravet på kontorsfastigheter av makroekonomiskaförändringar? : En kvantitativ studie av sambandet mellan direktavkastningskrav och makroekonomiska variabler

   Kandidat-uppsats, KTH/Fastigheter och byggande

   Författare :Rusen Yilmaz; Viktor Edlund; [2019]
   Nyckelord :Cap rate; macro-economic variables; regression analysis; Direktavkastningskrav; makroekonomiska variabler; regressionsanalys;

   Sammanfattning : Den svenska kontorsmarknaden har under senare år drivits mot rekordhöga hyror och lågadirektavkastningskrav. Drivkraften i utvecklingen har varit gynnsamma makroekonomiskaförhållanden med bland annat negativ reporänta. LÄS MER
