1. 1. Laser Scattering for Fast Characterization of Cellulose Filaments

   University essay from KTH/Fiber- och polymerteknologi

   Author : Alexandra Konstantinidou; Saga Holmström; Susanna Hellberg; [2022]
   Keywords : Cellulose nanofibrils; Fibers; Sustainable development; Bio-based material; Characterization; Microscale; Microscopy; Small-angle light scattering; Laser diffraction; Cellulosananofibriller; Fiber; H˚allbar utveckling; Biobaserade material; Karakterisering; Mikroskala; Mikroskopi; Ljusspridning; Laserdiffraktion;

   Abstract : Cellulosananofibriller (CNFs) hör till naturens mest fundamentala byggstenar och förser naturliga material, såsom den yttre cellväggen i trä, med en otrolig styrka och styvhet. Genom att imitera träets arkitektur öppnas möjligheter upp för tillverkning av nya, biobaserade och lättviktiga strukturella material med mekaniska egenskaper som överskrider de för glasfiber, metaller och legeringar.

3. 2. Individual Musculoskeletal Characteristics of Runners and Advanced Footwear Technology

   University essay from Gymnastik- och idrottshögskolan, GIH/Institutionen för fysisk aktivitet och hälsa

   Author : Sebastian Stattin; [2022]
   Keywords : Advanced Footwear Technology; AFT; Running Mechanics; Anthropometry; Neuromuscular Characteristics; Sports Equipment;

   Abstract : Background: In recent years, sudden improvements in long-distance running performance have been suggested to be due to the latest technological innovations in running footwear. However, inter-individual differences appear to be large in the performance enhancing effect these shoes elicit where some runners experience a decline in performance while others improve substantially.

4. 3. Automated Construction- Reinforcement : Lifting Prefabricated Reinforcement Cages

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Markus Pettersson; Andreas Larsson; [2021]
   Keywords : Tied rebar cage lift; Tied connection; Connecting rebars; Finite Element Modeling; Geometric to numerical model; Integration CAD and CAE; Lyft av najad armeringskorg; Najad knutpunkt; Sammanfogning av armering; Finita Element modellering; Geometrisk till numeriskmodell; Integration mellan CAD och CAE;

   Abstract : The construction industry is moving towards an increasingly industrial production and one step towards this is to use prefabricated rebar cages. A new concept is being tested where tied rebar cages are produced on the construction site by industrial robots. READ MORE

5. 4. 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

6. 5. Consequences of Magnetic Properties in Stainless Steel for a High-efficiency Wave Power Generator

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Mohamed Sheikh Abdi; Yosef Gebresilassie; [2018]
   Keywords : stainless steel; wave power; permeability;

   Abstract : A new kind of wave power generator is being developed at KTH Royal Institute of Technology which potentially can reach an efficiency of 98 %. However, this generator’s small air gap sets strict requirements on the stiffness of the structure to withstand the large magnetic forces. The structure, therefore, need to be both stiff and non-magnetic. READ MORE
