  1. 11. Enhancing on-line information sharing systems

    Författare :Alex Jonsson; KTH; []
    Nyckelord :workflow; news; concurrent; electronic publishing; newspaper; on-line; scripting; automation; multi-channel publishing; IP-based networks; Internet; intranet; distributed education; e-learning; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis presents working methods for developing andmaintaining publishing services for various purposes overIP-based computer networks. Many companies and organizationsthat plan to host an on-line service on the Internet or on acorporate intranet already have much of the required apparatusand in-house knowledge in their existing infrastructure.

  3. 12. Proposing Combined Approaches to Remove ECG Artifacts from Surface EMG Signals

    Författare :Sara Abbaspour; Maria Lindén; Urban Wiklund; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Electromyography (EMG) is a tool routinely used for a variety of applications in a very large breadth of disciplines. However, this signal is inevitably contaminated by various artifacts originated from different sources. LÄS MER

  4. 13. Monitoring of Cellular Dynamics with Focus on Electrochemical Detection Techniques

    Författare :Arto Heiskanen; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microfluidic system; Microchip; PC12; Saccharomyces cerevisiae; Electrochemical impedance spectroscopy; Cell adhesion; Amperometry; Exocytosis; Redox environment; Cell-based assay;

    Sammanfattning : This thesis presents work in two main areas of focus, the development of electroanalytical techniques to monitor the dynamics of cellular processes as well as design and fabrication of microelectrode chips for electrochemical detection as well as a prototype microfluidic system to be used for cell analysis and culturing. The electrochemically monitored cellular parameters were the cellular redox environment (CRE), cell adhesion and exocytosis. LÄS MER

  5. 14. Bluetooth and Wireless Multihop Networks in Industrial Communication Systems

    Författare :Urban Bilstrup; Orazio Mirabella; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bluetooth; industrial communication systems; short range devices; wireless multihop networks; wireless sensor networks; real-time communication; resource allocation; Computer engineering; Datorteknik; Datatransmission; Datatransmission;

    Sammanfattning : The objective of this thesis is to investigate the use of short-range wireless communication technology in industrial communication systems where there is a need for guaranteed timely delivery of correct information. Methods for achieving such capability are developed in the context of the physical layer, the data link layer and the application layer. LÄS MER

  7. 15. High-Tc SQUIDs for magnetophysiology - development of a magnetometer system and measurements of evoked fields from hippocampal neurons in vitro

    Författare :Per Magnelind; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neuromagnetism; brain slice; neurophysiology; electrophysiology; hippocampus; biomagnetism; SQUID;

    Sammanfattning : This thesis concerns development of a system based on a high-transition-temperature superconducting quantum interference device (high-Tc SQUID) magnetometer. The system has been designed and used for magnetic field recordings from brain slices, i.e. magnetophysiology. LÄS MER
