    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spintronics; X-ray photoemission; XPS; XMCD; XAS; magnetic semiconductors; HIKE; HAXPES; multilayer; monte carlo; magnetism; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : Materials exhibiting new functionalities due to interdependent electric (e.g. conductivity) and magnetic properties are potentially interesting for spintronics applications. READ MORE

  4. 22. Topics in Localization and Mapping

    Author : Jonas Callmer; Fredrik Gustafsson; Bo Bernhardsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor fusion;

    Abstract : The need to determine ones position is common and emerges in many different situations. Tracking soldiers or a robot moving in a building or aiding a tourist exploring a new city, all share the questions ”where is the unit?“ and ”where is the unit going?“. This is known as the localization problem. READ MORE

  5. 23. Integrated microsystems for continuous glucose monitoring, interstitial fluid sampling and digital microfluidics

    Author : Federico Ribet; Niclas Roxhed; Göran Stemme; Boris Stoeber; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microelectromechanical systems MEMS ; biosensors; biomedical devices; continuous glucose monitoring CGM ; glucose sensors; microneedles; interstitial fluid sampling; minimally-invasive technologies; electrochemical sensors; heterogeneous integration; wire bonding; magnetic assembly; electrowetting-on-dielectric EWOD ; digital microfluidics; ionic liquids; gas sensors; optical switches; laser shutters.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Interdisciplinary research between medicine and microsystem engineering creates new possibilities to improve the quality of life of patients or to further enhance the performance of already existing devices. In particular, microsystems show great potential for the realization of biosensors and sampling devices to monitor bioanalytes with minimal patient discomfort. READ MORE

  6. 24. On-scalp MEG using high-Tc SQUIDs: Measuring brain activity with superconducting magnetometers

    Author : Christoph Pfeiffer; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-Tc SQUID; neuroimaging; magnetoencephalography; localization; on-scalp MEG; sensor array; magnetometer;

    Abstract : This thesis describes work done towards realizing on-scalp magnetoencephalography (MEG) based on high critical temperature (high- T c) superconducting quantum interference device (SQUID) sensors. MEG is a non-invasive neuroimaging modality that records the magnetic fields produced by neural currents with good spatial and high temporal resolution. READ MORE

  7. 25. Aspects on measuring electrical current utilizing magnetic zero-flux technique

    Author : Maria Hammarqvist; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Current Transformer; AC Current; Frequency Response; Measurement Uncertainty; Traceability; Zero-Flux Measurement Technique; Zero-Flux;

    Abstract : The utilization of high accuracy measurements of electrical quantities is a prerequisite for the development of modern society. Generally, measurements serve different purposes and hence the criteria for the measurement equipment and method are different. READ MORE
