  1. 1. Road traffic noise reduction by multiple scattering and absorption mechanisms

    Författare :Bart van der Aa; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Outdoor sound propagation; Sonic crystals; Road traffic noise; FDTD; Noise barriers; MST; Porous materials; 2.5D MST; Graded index sonic crystals;

    Sammanfattning : Millions of people in Europe, and even more on a global scale, are affected by environ- mental noise. Traffic related noise is estimated to cause a yearly loss of approximately one million healthy life years in Western Europe, which is mostly related to road traffic noise. LÄS MER

  2. 2. The Making of Resistance : Brazil’s Landless Movement and Narrative Enactment

    Detta är en avhandling från Stockholm : Department of Economic History, Stockholm University

    Författare :Markus Lundström; Paulina de los Reyes; Fredrik Uggla; Stellan Vinthagen; [2017]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MST; Movimento dos Trabalhadores Rurais Sem Terra; peasant; Brazil; social movement; autonomy; constructive resistance; historiography; narrative; collective memory; identity; subject formation; focus group interview; corpus analysis; meta-analysis; Economic History; ekonomisk historia;

    Sammanfattning : This dissertation explores the story of Brazil’s Landless Movement: its historiographical prequel, its narrative components, its modifications, its enactment. The study derives from a non-essentialist understanding of the resistance agent, here construed as political subject – a collective of individuals, contingently unified in a specific political struggle, not necessarily representing a mutual material need, nor a common identity.

  3. 3. Integrated Communications and Thermal Management Systems for Microsystem-based Spacecraft A Multifunctional Microsystem Approach

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Henrik Kratz; Anders Rydberg; Johan Köhler; Pelle Rangsten; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; nanospacecraft; MST; MEMS; silicon; communication; thermal management; antenna; paraffin; PCM; multifunctional; microsystems; Elektronik; TECHNOLOGY Electrical engineering; electronics and photonics Electronics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektronik;

    Sammanfattning : This thesis explores the potential of multifunctional silicon-based microsystems for advanced integrated nanospacecraft (AIN). Especially, multifunctional microsystems with the coexistant functions of communications and thermal management implemented in multilayer silicon stacks are approached with systems study. LÄS MER

  4. 4. Fluidic Microsystems for Micropropulsion Applications in Space

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Johan Bejhed; Johan Köhler; Anders Eriksson; Greger Thornell; Thomas Laurell; [2006]
    Nyckelord :Engineering physics; microelectromechanical systems; MEMS; MST; microsystem; microfluidics; silicon; spacecraft; propulsion; space technology; Teknisk fysik;

    Sammanfattning : Spacecraft on interplanetary missions or advanced satellites orbiting the Earth all require propulsion systems to complete their missions. Introducing microelectromechanical systems technology to the space industry will not only reduce size and weight of the propulsion system, but can also increase the performance of the mission.

  5. 5. Miniature Plasma Sources for High-Precision Molecular Spectroscopy in Planetary Exploration

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Martin Berglund; Greger Thornell; Anders Persson; Felipe Iza; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEMS; MST; Optogalvanic Spectroscopy; Molecular Spectroscopy; Split-Ring Resonator; Microplasma; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Sammanfattning : The prospect of finding life outside Earth has fascinated mankind for ages, and new technology continuously pushes the boundary of how remote and how obscure evidence we can find. Employing smaller, or completely new, types of landers and robots, and equipping them with miniature instruments would indeed revolutionize exploration of other planets and moons. LÄS MER
