  1. 11. Verification of the local similarity theory above forests

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Yasmin Hubmann; [2021]
    Keywords : Forest Meteorology; Boundary Layer Meteorology; Wind Energy; Local Similarity Theory; Monin–Obukhov Similarity Theory; Flux-Gradient Formulation; Richardson Number Formulation; Turbulence Statistic; Rotor Equivalent Wind Speed; Grenzschicht-Meteorologie; Forstmeteorologie; Windenergie; Lokale Ähnlichkeitstheorie; Monin–Obukhov’sche Ähnlichkeitstheorie; Fluss-Gradient-Ähnlichkeit; Gradient-Richardson-Zahl Beziehung; Turbulenzcharakteristiken; Rotor-äquivalente Windgeschwindigkeit; Skogsmeteorologi; Gränsskiktsmeteorologi; Vindenergi; Lokal Similaritetsteori; Monin–Obukhov Similaritetsteori; Flöd-Gradient Relation; Richardson Gradienttal Relation;

    Abstract : In this study, the local similarity theory functions were calculated with two different approaches and on the other hand the mean hub height wind speed was compared with the rotor equivalent wind speed. Both calculations are based on two independent data-sets from measurement campaigns Hornamossen and Ryningsnäs which were conducted in the south of Sweden between May 2015 and June 2017, and November 2010 and February 2012.

  3. 12. Product development of an end-effector for a collaborative robot

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Nils Söderström; [2020]
    Keywords : Participatory action research; Collaborative robot; Robot integration; Product development; Deltagande aktionsforskning; Kollaborativ robot; Robot integration; Produktutveckling;

    Abstract : With the ever-growing market of six-axis robots in the previous years, many different kinds of robots have been introduced into the market. A smaller group of so-called collaborative robots have during this time gotten increased popularity. READ MORE

  4. 13. Forecasts with uncertainties for calculating electricity reserves

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Christian Nallatamby; [2020]
    Keywords : ;

    Abstract : The continued growth of renewable energy sources modifies the established electricity system. Power generation reserves are a vital part of this system as they are used to balance out the load fluctuations and the natural intermittence of renewables. The management of power reserves is largely impacted by the ongoing trend. READ MORE

  5. 14. The spatial distribution of dark matter in the Universe

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Tamina Lund; [2020]
    Keywords : dark matter halos; NFW profile; curve fitting; Bayesian inference; least Squares; data uncertainties; Physics and Astronomy;

    Abstract : It was previously found that the density profile of dark matter halos is well-fit by a universal, smooth function over a vast range of masses and redshifts, named the Navarro-Frenk-White (NFW) profile after its discoverers. Despite its impressive goodness of fit, the NFW model remains an approximation of the density profile of realistic halos. READ MORE
