  3. 22. High Aspect Ratio Microstructures in Flexible Printed Circuit Boards : Process and Applications

    Författare :Hanna Yousef; Klas Hjort; Mikael Lindeberg; Peter Leisner; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; flexible printed circuit boards; polyimide; through-hole vias; ion track technology; thermoelectricity; thermopiles; substrate integrated waveguides; millimeter wave devices; Teknisk fysik; Engineering physics; Teknisk fysik;

    Sammanfattning : Flexible printed circuit boards (flex PCBs) are used in a wide range of electronic devices today due to their light weight, bendability, extensive wiring possibilities, and low-cost manufacturing techniques. The general trend in the flex PCB industry is further miniaturization alongside increasing functionality per device and reduced costs. LÄS MER

  4. 23. Optimization of Vehicle Structures under Uncertainties

    Författare :Sandeep Shetty; Larsgunnar Nilsson; Kaj Fredin; Alexander Govik; Mårten Olsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Advancements in simulation tools and computer power have made it possible to incorporate simulation-based structural optimization in the automotive product development process. However, deterministic optimization without considering uncertainties such as variations in material properties, geometry or loading conditions might result in unreliable optimum designs. LÄS MER

  5. 24. Flexible Authoring of Metadata for Learning : Assembling forms from a declarative data and view model

    Författare :Fredrik Enoksson; Olle Bälter; Ambjörn Naeve; Pawlowski Jan; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metadata; RDF; Semantic Web; metadata editors; metadata authoring; Computer science; Datavetenskap;

    Sammanfattning : With the vast amount of information in various formats that is produced today it becomes necessary for consumers ofthis information to be able to judge if it is relevant for them. One way to enable that is to provide information abouteach piece of information, i.e. provide metadata. LÄS MER

  7. 25. Studies in extended unification-based formalism for linguistic description : an algorithm for feature structures with disjunction and a proposal for flexible systems

    Författare :Lena Strömbäck; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Unification-based formalisms have been used in computational and traditional linguistics for quite some while. In these formalisms the feature structure is the basic structure for representing linguistic information. LÄS MER
