  2. 1. Reconfigurable and Wideband Receiver Components for System-on-Chip Millimetre-Wave Radiometer Front-Ends

    Author : Shakila Bint Reyaz; Robert Malmqvist; Anders Rydberg; Luca Roselli; Uppsala universitet; []
    Keywords : Reconfigurable; Wideband; Receivers; Millimetre-Wave; Radiometers; System-on-Chip; Passive Imaging.; Engineering Science with specialization in Microwave Technology; Teknisk fysik med inriktning mot mikrovågsteknik;

    Abstract : This thesis presents solutions and studies related to the design of reconfigurable and wideband receiver circuits for system-on-chip (SoC) radiometer front-ends within the millimetre-wave (mm-wave) range. Whereas many of today’s mm-wave front-ends are bulky and costly due to having discrete RF components, single-chip receiver modules could potentially result in a wider use for emerging applications such as wireless communication, short range radar and passive imaging security sensors if realised with adequate performances and at a lower cost.

  4. 2. Team activities in concept development : Addressing open-ended problems

    Author : Johan Wenngren; Pasi Tyrväinen; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Informationssystem; Information Systems; Effective innovation and organisation AERI ; Effektiv innovation och organisation FOI ; Enabling ICT AERI ; Möjliggörande IKT FOI ; Intelligenta industriella processer FOI ; Intelligent industrial processes AERI ;

    Abstract : The concept development stage is a fundamental part of the development process; in this early stage, teams define what constitutes the problem and find direction for the subsequent problem-solving activities. Concept development that searches for innovative results starts from a problem formulation, or design brief, that should not be too precise; keeping parts open for interpretation and alternatives is important for allowing for the possibility to create new solutions.

  6. 4. Phospholipid membranes in biosensor applications : Stability, activity and kinetics of reconstituted proteins and glycolipids in supported membranes

    Author : Inga Gustafson; Gertrud Puu; Sven Lindskog; Peter Konradsson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Phospholipid films; Liposomes; Membrane proteins; Glycolipids; Ellipsometry; Langmuir Blodgett LB ; Surface plasmon resonance SPR ; Resonant mirror RM ; Atomic force microscopy AFM ; Biosensors; Biokemi; Biochemistry; Biokemi; Biochemistry; biokemi;

    Abstract : In this study the formation of supported membranes onto planar solid supports has been investigated. The stability and activity of reconstituted membrane receptors has been studied. The potential use of such preparations in biosensor applications is discussed.The lipid films were made by the Langmuir Blodgett and by the liposome fusion techniques. READ MORE

  7. 5. Efficient Web Services for End-To-End Interoperability of Embedded Systems

    Author : Rumen Kyusakov; Frank Golatowski; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Web services; Embedded; EXIP; EXI; WSN; XML; Interoperability; SOA; Industriell elektronik; Industrial Electronics; Intelligenta industriella processer FOI ; Intelligent industrial processes AERI ;

    Abstract : As the number of Internet-connected devices rapidly grows, it has become ever more challenging to develop and maintain purpose-made tightly integrated distributed embedded systems. Instead, the Internet of Things (IoT) approach, based on standardized interfaces and open communication protocols, enables support for various applications with the possibility of extension to provide additional services that were not necessarily available at the initial deployment.
