  3. 2. Aeroelastic Concepts for Flexible Wing Structures

    Författare :Sebastian Heinze; Ulf Ringertz; Bengt Winzell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active aeroelasticity; flexible wings; aeroelastic control; design; experiments; testing; analysis; robust; uncertainty; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : This thesis summarizes investigations performed within design, analysis and experimental evaluation of flexible aircraft structures. Not only the problems, but rather the opportunities related to aeroelasticity are discussed. LÄS MER

  4. 3. X-ray - Based Studies of Structural Dynamics in Solids and Liquids

    Författare :Ralf Nüske; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The wavelength of x-ray radiation is much shorter than that of visible light. In fact, it is comparable to the distances between atoms in solids, which is on the order of one tenth of a nanometer. Using light of such a short wavelength, it is possible to study the structure of materials on the atom level. LÄS MER

  5. 4. Introducing Power Control and Link Adaptation in Flooding-based Underwater Networks : Extending the applicability of flooding-based routing protocols

    Författare :Elias Erstorp; Jacob Kuttenkeuler; Roald Otnes; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustic Underwater Networks; Distributed Power Control; Link Adaptation; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : Underwater communication and networking are key enabling technologies for many current and future marine applications. Generally, the envisioned applications include environmental monitoring, aquaculture, and surveillance. LÄS MER

  7. 5. Turbo Charged Low Temperature Combustion - Experiments, Modeling and Control

    Författare :Hans Aulin; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HCCI; PPC; CAI; NVO; low temperature combustion; torductor; ion current; control; modeling; combustion feedback; sensors;

    Sammanfattning : Both the global economy and the society in general are dependent on the availability of reliable transportation. Most transportation technology involves the use of internal combustion engines in one way or another. LÄS MER
