  1. 16. Remote control of mechanical rat traps based on vibration and audio sensors

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Denis Solak; Amin Storani; [2019]
    Keywords : Technology and Engineering;

    Abstract : The main aim with this master’s thesis was to study the possibilities of detecting an event (rat trap going off) by analyzing audio streams from a MEMS (micro-electromechanical systems) microphone or movement patterns from a MEMS accelerometer. To achieve this goal, a small, power efficient and cost efficient embedded system was built with the help of a development board, a MEMS accelerometer, a MEMS microphone and a metal box where the equipment and the rat traps were placed and positioned.

  3. 17. Comparison of Consumer-Grade MEMS IMUs in UBI Context

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

    Author : Tolga Varol; [2019]
    Keywords : IMU; UBI; IMU array; multi-IMU; BMI160;

    Abstract : Road traffic has many negative socioeconomic impacts on society. A key problem is the risk of deadly accidents. The risk, to a high extend is reduced in developed societies. However, the accidents are still ubiquitous. READ MORE

    Keywords : ;

    Abstract : Today there are a vast amount of headphones models, brands and types – each trying their bestto differentiate themselves from the rest. In collaboration with Defunc the thesis project soughtto investigate how one can develop a pair of mobile gaming headphones that meet the needsand wants of mobile gamers. READ MORE

  5. 19. Improving thermal fracture resistance in ceramic microcomponents for spacecraft propulsion

    University essay from Uppsala universitet/Ångström Space Technology Centre (ÅSTC)

    Author : Erika Åkerfeldt; [2018]
    Keywords : HTCC; MEMS; MST; microthruster; thermal fracture;

    Abstract : Because of thermal transients and gradients occurring upon rapid heating or cooling, microcomponents made from High-Temperature Co-fired Ceramics (HTCC) often fail at temperatures far below what the materials can withstand per se. This work investigates how resistance to thermal fracture in HTCC microcomponents can be increased by improving the component design, aiming at increasing the thermal performance of a microthruster with integrated heaters.

  6. 20. Review on Mechanistic Effect Models Used in Ecological Risk Assessment of Pesticides According to the European Food Safety Authority Guidance

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Qin Wang; [2018]
    Keywords : mechanistic effect model; ecological risk assessment; pesticide; dynamic energy budget; extrapolation.;

    Abstract : In ecological risk assessment, mechanistic effect models (MEMs) are thought to overcome the limitation of standard laboratory single species test by accurately extrapolating the models to population-level. This review introduces the basic theory of MEMs-dynamic energy budget theory which can connect with toxicokinetic/ toxicodynamic models to describe the interaction of toxicants and organisms.
