  1. 1. Lumina – An Exploration of How Interactive Lights Can Support Mindfulness

    University essay from Malmö universitet/Fakulteten för kultur och samhälle (KS)

    Author : Leyla Allendes; [2020]
    Keywords : Brain-computer interface; research through design; mindfulness; calm technology; ambient display.;

    Abstract : This thesis project presents a research through design process that has aimed to explore how we can design interactive technologies that can support mindfulness practices in beginners. This has been done by designing a meditative lamp, Lumina, which can be controlled by the user’s neural oscillations. READ MORE

  3. 2. Wireless communication using metasurfaces for condition monitoring in motor

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

    Author : Neelu Kambisseri Roby; [2018]
    Keywords : Gap waveguide; metasurface; holey electromagnetic band gap EBG structures; periodic structures; parallel plate mode.; Gap vågledare; metaytor; håliga elektromagnetiskta bandgap-strukturer EBG ; periodiska strukturer; parallellplattform.;

    Abstract : Wireless sensors are used widely for condition monitoring in electric machines. The metal enclosure of an electric motor restricts the signal from sensors to radiate outside. The signal from the metal cavity needs to be guided to the only opening in the enclosure, through a narrow gap between the stator and the rotating rotor. READ MORE

  4. 3. Wave study Seaflex mooring system : Wave study to illuminate how first and second order wave force transfer to and affects the loading of flexible Seaflex mooring system

    University essay from Umeå universitet/Institutionen för fysik

    Author : Magnus Berggren; [2018]
    Keywords : ;

    Abstract : When constructing a marina, one must consider many factors for calculating the mooring forces transferred to the mooring system of the docks. The forces transferred from waves is of course one of the most important. READ MORE

  5. 4. Semi-Analytical Finite Element method for guided waves in civil engineering plate-like structures

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Christian Nielsen; [2015]
    Keywords : seismics; structural health monitoring; lamb waves; SAFE; semi analytical finite element; wave guide finite element; non destructive testing; civil engineering; ultrasound; ultrasonography; comsol; wave guide; plate; Technology and Engineering;

    Abstract : Guided waves have a signicant potential for Structural Health Monitoring (SHM) and Non-Destructive Testing (NDT) due to their relatively long distance of propagation and sensitivity to discontinuities along the propagation path, anywhere through the material thickness. The inability to model wave guides of arbitrary cross-section using current matrix methods, has led to the development of a technique called Semi-Analytical Finite Element (SAFE). READ MORE

  6. 5. Fabrication of channel waveguides in LiNb03.

    University essay from KTH/Fysik

    Author : Hanna Al-Maawali; [2011]
    Keywords : ;

    Abstract : In this bachelor’s thesis, a fabrication process for channel waveguides in LiNbO 3crystals using the proton exchange technique is developed and characterized. These waveguides can be used at the laser physics department at the Royal Institution of Technology, KTH, for specifically non-linear optical applications. READ MORE
