1. 21. Aerodynamic Studies of Vertical Axis Wind Turbines using the Actuator Line Model

   Författare :Victor Mendoza; Anders Goude; Hans Bernhoff; Robert Flemming Mikkelsen; Uppsala universitet; []
   Nyckelord :wind power; vertical axis wind turbines VAWTs ; actuator line model ALM ; dynamic stall model DSM ; atmospheric boundary layer ABL ; wake deflection; atmospheric boundary layer ABL ; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Sammanfattning : This thesis addresses the unsteady aerodynamics involved in the operation of vertical axis wind turbines (VAWTs). The main focus is to represent and understand the most relevant phenomena within the resulting flow pattern as the wake structure, loads on the different turbine components and the performance of the rotor.

3. 22. Measurements of hard X-ray polarization from the Crab and Cygnus X-1

   Författare :Victor Mikhalev; Mark Pearce; Herman Marshall; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics; Fysik; Physics;

   Sammanfattning : Polarimetry provides insights into the emission mechanisms of astrophysical sources by elucidating their magnetic field and geometry. Hard X-rays are produced in \mbox{regions} with strong magnetic fields or strong gravitational effects, which makes them a probe of extreme environments. LÄS MER

4. 23. A Timely Journey Through the Cloud

   Författare :Victor Millnert; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-Time Systems; Cloud; End-to-End Deadlines; Control Theory; Dynamic Networks; AutoSAC; Horizontal Scaling; Admission Control; Virtual Network Functions; Forwarding Chains; Network Calculus;

   Sammanfattning : This thesis treats the intersection between two of the largest transformations we are seeing within our society today; the cloud and the Internet-of-Things (IoT). The aim of this thesis is to investigate different ways to model and control a network of cloud services so that timing-critical IoT applications can make use of them. LÄS MER

5. 24. The Queerness of Objective Values : An Essay on Mackiean Metaethics and the Arguments from Queerness

   Författare :Victor Moberger; Jens Johansson; Erik Carlson; Russ Shafer-Landau; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; J. L. Mackie; argument from queerness; objective values; moral realism; claim to objectivity; argument from relativity; non-naturalism; supervenience; normative explanation; authoritative prescriptivity; objectivity; categoricity; minimal realism; ardent realism; Filosofi; Philosophy;

   Sammanfattning : This book investigates the argument from queerness against moral realism, famously put forward by J. L. Mackie in Ethics: Inventing Right and Wrong (1977). The book can be divided into two parts. LÄS MER

7. 25. Processing–Structure–Properties Relationship in Metal Additive Manufacturing

   Författare :Victor Pacheco; Martin Sahlberg; Ulf Jansson; Premysl Beran; Joe Kelleher; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; additive manufacturing; selective laser melting; preferential orientation; neutron imaging; metallic glasses;

   Sammanfattning : The last three decades have seen the transition of additive manufacturing, from applications exclusively in rapid-prototyping to an emerging production method in the manufacturing industry that is rapidly gaining more relevance. Within additive manufacturing methods, selective laser melting (SLM) is one of the most widely used and mature technologies and is the focus of this thesis.
