1. 21. Methods for Studying Influence of Io Magma Ocean on Alfvén Wings

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

   Author : Carl Lundquist; Fredrik Cumlin; [2020]
   Keywords : Io; magma ocean; Alfv ́en wings; plasma; mag-netic induction;

   Abstract : The most volcanically active body in the solar systemand the innermost Galilean moon of Jupiter, Io, is theorizedto have a global magma ocean beneath it’s surface. Io is alsoin a fast-moving flow of plasma where the moon acts as anobstacle in the flow which generates several complex interactions. READ MORE

3. 22. Effects of cracking of coupling beams onhigh rise towers subjected to wind load

   University essay from KTH/Betongbyggnad

   Author : Brook Worku Woldemikael; [2020]
   Keywords : Crack; reinforcement content; aspect ratio; shear deformation; joint flexibility; concrete grade; effective stiffness.; Sprickor; förstärkningsinnehåll; tvärsnittsförhållande; skjuvdeformation; ledflexibilitet; betongkvalitet; effektiv styvhet;

   Abstract : In high rise towers, reinforced concrete elevator shafts with coupling beams are extensively used as a principal structural element to resist lateral loads. The lateral load resistance of the tower is dominantly dependent on the stiffness of the load-bearing walls, and coupling beams connecting them. READ MORE

4. 23. Two-dimensional roughness and Tollmien-Schlichting waves: a study on transition

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Derek Micheletto; [2020]
   Keywords : ;

   Abstract : Two-dimensional (2D) roughnesses induce premature transition to turbulence in laminar boundary layers by amplifying the disturbances in the flow and promoting the development of non-linearities. The present thesis aims at furthering our understanding of this phenomenon's underlying mechanisms and elucidating the effects of the different geometrical parameters of the roughness' cross section.

5. 24. Reinforced Concrete Structures Subjected to Imposed Deformations: A Study of Cracking due to Shrinkage in Slab Foundations for Residential Houses

   University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

   Author : Henrik Johansson; Martin Heinegård; [2020]
   Keywords : Reinforced concrete structures; nonlinear finite element analysis; crack widths; imposed deformations; shrinkage; foundation slabs; fracture mechanics; Atena 2D; Technology and Engineering;

   Abstract : The need for limiting crack widths in reinforced concrete structures is due to durability, tightness towards gaseous and liquid substances, and for aesthetic reasons. Although concrete cracks at relatively low tensile stresses and can not be avoided, strategies for crack control can be adopted to meet the requirements. READ MORE

6. 25. Design of Eccentric Double Amplitude Vibration Drum Roller Shaft with Improved Mass Moment of Inertia : Product Development of Compaction Equipment

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Marika Blad; Alexander Tynnerstål Balog; [2020]
   Keywords : Eccentricity; mass moment of inertia; double amplitude feature; vibration; Excentricitet; masströghetsmoment; dubbelamplitud; vibration;

   Abstract : Road construction is important to make transports safe and sustainable. To compact asphalt an amount of energy needs to be conducted into the material either by static pressure or dynamic vibrations. An asphalt-roller compact the material and increases its load-bearing capacity. READ MORE
