  1. 1. Morphology Formation from Ternary Mixtures upon Evaporation : a Square Cell Model Approach

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Simon Kronberg; [2019]
    Keywords : Lattice model; Morphology; Ternary mixtures; Monte Carlo method;

    Abstract : We present a novel modelling approach for the morphology formation from ternary mixtures upon evaporation, which takes into consideration two different length scales of the interaction, and further allows for these length scales to be altered. A quantitative study of the interfacial energy hints towards the existence of a mesoscopic regime - further research is needed to verify the validity of this claim however. READ MORE

  2. 2. THE EFFECTS OF VISUAL SUPPORT BY A THREEDIMENSIONAL STAIRCASE MODEL ON INDOOR NAVIGATION AND SPATIAL ORIENTATION DURING VERTICAL MOTION

    University essay from Umeå universitet/Institutionen för psykologi; Umeå universitet/Institutionen för psykologi

    Author : Sofia Larsson; Pauline Mattsson; [2019]
    Keywords : Indoor navigation; spatial ability; vertical motion; visual aid; Inomhusnavigering; spatial förmåga; vertikal rörelse; visuellt hjälpmedel;

    Abstract : Vertikala strukturer i byggnader har blivit väldigt vanligt och mer komplexa, därmed ökar vikten av wayfinding. Syftet med denna studie var att undersöka om en tredimensionell modell av en spiraltrappa ökar spatiala orienteringen när man rör sig vertikalt via den motsvarande existerande trappan. READ MORE

  3. 3. Experimental and Theoretical Investigation of Selective Laser Melted Uddeholm Dievar ®

    University essay from KTH/Materialvetenskap; KTH/Materialvetenskap

    Author : Sanjin Pepić; Otto Ridemar; [2019]
    Keywords : Uddeholm Dievar®; Additive manufacturing; AM; Selective laser melting; SLM; Gas-atomization; Hot-work tool steel; Uddeholm Dievar®; Additiv tillverkning; AM; Selective laser melting; SLM; Gas- atomisering; Varmarbetsverktygsstål;

    Abstract : The main problem encountered in this thesis is the lack of research and knowledge of selective laser melted-printing with Uddeholm Dievar®. This absence of information could cause issues regarding quality and properties of the alloy as well as uncertainty regarding an appropriate heat treatment cycle. READ MORE

  4. 4. Modelling cross-laminated timber floors in dynamic analysis - Eigenfrequency prediction

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Author : Johannes Wetterholt; [2019]
    Keywords : finite element method; FEM; dynamic analysis; Eigenfrequency; CLT; cross-laminated timber; cross-laminated timber floors; wooden floors; Technology and Engineering;

    Abstract : In the late 1990s cross-laminated timber (CLT) was developed. The development of CLT was a project aimed to produce a structural product that could compete with the concrete industry and contribute to a reduced effect on the environment, due to the low environmental impact of timber in relation to other building materials.

  5. 5. Towards unification of organ labeling in radiation therapy using a machine learning approach based on 3D geometries

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

    Author : Giorgio Ruffa; [2019]
    Keywords : ;

    Abstract : In radiation therapy, it is important to control the radiation dose absorbed by Organs at Risk (OARs). The OARs are represented as 3D volumes delineated by medical experts, typically using computed tomography images of the patient. READ MORE
