  1. 21. Serviceability assessment of footbridges when subjected to vibrations induced by running pedestrians

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Javier Garmendia Purroy; [2017]
    Nyckelord :Footbridge; Running; Jogging; Load; Vibrations; Structural; Dynamics; Pedestrian footbridge interaction; Serviceability; Assessment; Gångbro; Löpning; Last; Vibrationer; Strukturdynamik; Bruksgränstillstånd; Bedömning;

    Sammanfattning : Vibration serviceability in the design of footbridges is gathering enormous prominence as comfort restrictions get enhanced. Comfort verifications are often becoming critical when considering human induced dynamic loading on lightweight structures, which are increasing in slenderness and flexibility. LÄS MER

  3. 22. ATT HJÄLPA ELLER STJÄLPASANNOLIKHETSBEDÖMNINGAR:KONJUNKTIONSREGELN OCH MENTALARBETSBELASTNING SOM MEDIERANDEFAKTORER

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för psykologi

    Författare :Erik Jonsson; Kristina Leander; [2017]
    Nyckelord :heuristics; the conjunction rule; probability assessments; working memory; mental workload; dual process theory; single-process theory; nested-set view.; heuristik; konjunktionsregeln; sannolikhetsbedömningar; arbetsminne; mental arbetsbelastning; dualprocessteori; enkelprocessteori; nested-sets view.;

    Sammanfattning : Den här studien syftade till att undersöka om mental arbetsbelastning kan påverka benägenhetenatt begå konjunktionsfelet vid sannolikhetsbedömningar, trots att man fått ledtrådarsom synliggjort konjunktionsregeln. Detta undersöktes med en experimentell mellangruppsdesign. LÄS MER

  4. 23. Diffusion-adapted spatial filtering of fMRI data for improved activation mapping in white matter

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :David Abramian Petrosian; Martin Larsson; [2017]
    Nyckelord :functional MRI; diffusion MRI; activation mapping; filtering; white matter; spectral graph theory; Technology and Engineering;

    Sammanfattning : Brain activation mapping using fMRI data has been mostly focused on finding detections in gray matter. Activations in white matter are harder to detect due to anatomical differences between both tissue types, which are rarely acknowledged in experimental design. LÄS MER

  5. 24. Validation of simulation tool for C-arm X-ray systems : Source and scatter model

    Master-uppsats, KTH/Skolan för teknik och hälsa (STH)

    Författare :Martina Jurcova; [2016]
    Nyckelord :Simulation; C-arm system; X-ray imaging; focal spot; scattering; image sharpness;

    Sammanfattning : Continuous improvement of image quality is one of the priorities in medical imaging. Therefore, development of a simulation tool allowing to generate realistic images would be of great value to understand better the impact of the components on the image quality metrics and to choose imaging set-ups or new design features to optimize output of existing systems and to prototype new ones and to formalize the link between objective and subjective image quality metrics.

  7. 25. An Alternative Future of Spatial Materiality

    Master-uppsats, Konstfack/Inredningsarkitektur & Möbeldesign

    Författare :Katharina Sofie Kraus; [2016]
    Nyckelord :Material; Materials; Experimental; Furniture; Spatial Applications; Biodegradable; Sustainability; Up-Cycling; Waste Materials; Material Development;

    Sammanfattning : In our practice the choice of materials is mostly driven by practical reasons, aesthetics and a given budget, and it is often applied rather at the end of the process – rarely is it the driver of any design process. What often gets forgotten is that materials can carry an immaterial layer of connotations. LÄS MER
