  1. 1. Photonic MEMS for optical information technologies

    University dissertation from KTH Royal Institute of Technology

    Author : Carlos Errando-Herranz; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Micro-electro-mechanical systems MEMS ; photonics; silicon photonics; photonic integrated circuits PIC ; lithium niobate photonics; ring resonator; polarization beam splitter PBS ; microfluidic integration; lab-on-chip LoC ; optical beam steering; nonlinear optics; Electrical Engineering; Elektro- och systemteknik; Physics; Fysik; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : Photonic integrated circuits (PICs) combine hundreds of optical components on a chip, and can enable fast communications, high-performance computing, and improved sensing. PICs, made by miniaturized optical waveguides, require many reconfigurable elements to enable programmable functionalities and to compensate for fabrication variations and environmental factors.

  3. 3. Signal processing for MEMS sensor based motion analysis system

    University dissertation from Västerås : Mälardalen University

    Author : Jiaying Du; Mälardalens högskola.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Abstract : Sensor systems for motion analysis represent an important class of embeddedsensor systems for health, and are usually based on MEMS technology(Micro-electro-mechanical systems). Gyroscopes and accelerometers are two examples of MEMS motion sensors that are characterized by their small size,low weight, low power consumption, and low cost. READ MORE

  4. 4. Three-component digital-based seismic landstreamer Methodologies for infrastructure planning applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Bojan Brodic; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; landstreamer; multicomponent seismic; shear-waves; surface-waves; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : To support urban infrastructure planning projects, along with various other near-surface applications, a multicomponent landstreamer was developed. The landstreamer was built with broadband (0-800 Hz), three-component (3C) micro-electro-mechanical system (MEMS) sensors. READ MORE

  5. 5. On GPS receiver architectures

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Jonas Thor; Luleå tekniska universitet.; [2003]
    Keywords : ;

    Abstract : Navigation can be described as the art of finding the way from one location to another. Clearly navigation is something that we perform in our every day lives and the role of navigation can not be underestimated. There exist many technologies that implement various navigation systems to aid in this process. READ MORE
