  1. 1. Muspel and Surtr : CVD system and control program for WF6 chemistry

    Författare :Johan Gerdin Hulkko; Mats Boman; Tobias Törndahl; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CVD; W; WN; system; WF6; TiN; control program; LabView; CVD; W; WN; system; WF6; TiN; styrprogram; LabView; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Sammanfattning : CVD (Chemical Vapour Deposition) is an advanced technique for depositing a coating on a substrate. CVD implies that a solid phase is deposited on a normally heated substrate surface using a reactive, gaseous mixture. The reaction gas mixture must be carefully chosen to prevent homogeneous nucleation in the gas phase. LÄS MER

  4. 3. Integrating Visual Data Flow Programming with Data Stream Management

    Författare :Lars Melander; Tore Risch; Sharma Chakravarthy; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; data stream management; data stream visualization; visual data flow programming; LabVIEW; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Sammanfattning : Data stream management and data flow programming have many things in common. In both cases one wants to transfer possibly infinite sequences of data items from one place to another, while performing transformations to the data. LÄS MER

  5. 4. Development of Lidar Techniques for Environmental Studies

    Författare :Mats Andersson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The lidar group in Lund has performed many DIAL measurements with a mobile lidar system that was first described in 1987. The lidar system is based on a Nd: YAG-pumped dye laser. During the last few years the lidar group has focused on fluorescence imaging and mercury measurements in the troposphere. LÄS MER

  7. 5. User Effect Mitigation in MIMO Terminal Antennas

    Författare :Ivaylo Vasilev; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The rapid growth of cellular technology over the past decade transformed our lives, enabling billions of people to enjoy interactive multimedia content and ubiquitous connectivity through a device that can fit into the palm of a hand. In part the explosive growth of the smartphone market is enabled by innovative antenna system technologies, such as multiple-input multiple-output (MIMO) systems, facilitating high data rates and reliable connections.
