  2. 1. Screen Printing Technology for Energy Devices

    Author : Andreas Willfahrt; Xavier Crispin; Isak Engquist; Erich Steiner; Gunter Hübner; Tim Claypole; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; screen printing; printed electronics; energy converters; energy storage;

    Abstract : The technical application of screen and stencil printing has been state of the art for decades. As part of the subtractive production process of printed circuit boards, for instance, screen and stencil printing play an important role. With the end of the 20th century, another field has opened up with organic electronics. READ MORE

  4. 2. Flight strategies in migrating birds: when and how to fly

    Author : Martin Green; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; geese; waders; terns; Animal ecology; Djurekologi; wind tunnel; radio telemetry; satellite telemetry; radar; formation flight; flight speed adjustment; wind drift; energy savings; departure decisions; bird migration; wind;

    Abstract : Wind has a profound influence on migrating birds since it inevitably will influence travel time and energy expenditure. In this thesis I investigate how migrating birds are affected by, and use winds. READ MORE

  5. 3. Large-Scale Graphene Production for Environmentally Friendly and Low-Cost Energy Storage : Production, Coating, and Applications

    Author : Nicklas Blomquist; Håkan Olin; Renyun Zhang; Christina Dahlström; Patrik Johansson; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Graphene; Energy storage; Supercapacitors; EDLC;

    Abstract : There is great demand for energy-efficient, environmentally sustainable, and cost-effective electrical energy storage devices. One important aspect of this demand is the need for automotive electrification to achieve more energy-efficient transportation at a reasonable cost, thus supporting a fossil-fuel free society.

  6. 4. Dynamic Rating of Power Lines and Transformers for Wind Energy Integration

    Author : Kateryna Morozovska; Patrik Hilber; Rajeev Thottappillil; Rebei Bel Fdhila; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic line rating; dynamic transformer rating; power transformers; heat balance; thermal modeling; wind power; wind energy integration; reliability analysis; risk analysis; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Dynamic Rating (DR) is usually associated with unlocking the capacity of power lines and transformers using available information on weather conditions. Our studies show that Dynamic Rating is a broad concept that requires further study and development. READ MORE

  7. 5. Noise, eigenfrequencies and turbulence behavior of a 200 kW H-rotor vertical axis wind turbine

    Author : Erik Möllerström; Jonny Hylander; Fredric Ottermo; Hans Bernhoff; Göran Sidén; Mats Åbom; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VAWT; H-rotor; eigenfrequency; semi-guy-wired tower; noise emission; sound power level; microphone array; turbulence intensity; power curve; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Vertical-axis wind turbines (VAWTs) have with time been outrivaled by the today more common and economically feasible horizontal-axis wind turbines (HAWTs). However, VAWTs have several advantages which still make them interesting, for example, the VAWTs can have the drive train at ground level and it has been argued that they have lower noise emission.
