  2. 6. Analysis of the phase space, asymptotic behavior and stability for heavy symmetric top and tippe top

    Author : Markus Sköldstam; Stefan Rauch-Wojciechowski; Torkel Glad; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; symmetric top; tippe top; vertical rotation; truncated sphere; asymptotic trajectories; MATHEMATICS; MATEMATIK;

    Abstract : In this thesis we analyze the phase of the heavy symmetric top and the tippe top. These tops are two examples of physical systems for which the usefulness of integrals of motion and invariant manifolds, in phase space picture analysis, can be illustratedIn the case of the heavy symmetric top, simplified proofs of stability of the vertical rotation have been perpetuated by successive textbooks during the last century.

  4. 7. Studies on Haemproteins of Gram-positive Bacteria - Implications as Antibacterial Drug Targets

    Author : Peter Kjelgaard; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacteriology; virology; mycology; Mikrobiologi; Microbiology; heme; Truncated hemoglobins; cytochrome c maturation; cytochrome bd; ResB; bakteriologi; virologi; mykologi;

    Abstract : With the discovery of antibiotics, several diseases that were previously lethal is today readily cured, or so we thought. Some degree of resistance to one or several antibiotics can be found among many strains of clinical important bacteria. READ MORE

  5. 8. Investigations of Heat Transfer and Fluid Flow in the Pocket Region of a Gas Turbine Engine and Cooling of a Turbine Blade

    Author : Jian Liu; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pocket cavity; symmetric vane; Liquid Crystal Thermography; truncated ribs; staggered arrangement; perforated ribs; secondary flows; endwall film cooling; leading edge; turbine vane; coolant coverage;

    Abstract : In the present work, heat transfer within gas turbine applications are investigated bothexperimentally and numerically. The main content concerns heat transfer and fluidflow over the pocket region and cooling of a turbine blade. READ MORE

  6. 9. Architectures and Protocols for Performance Improvements of Real-Time Networks

    Author : Kristina Kunert; Magnus Jonsson; Elisabeth Uhlemann; Eduardo Tovar; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Real-time communication; predictable deadline guarantees; real-time scheduling analysis; timing analysis; admission control; deterministic medium access; MAC; Quality of Service parameters; reliability; redundancy; retransmission scheme; ARQ; truncated ARQ; Automatic Repeat Request; wireless networks; IEEE 802.11; IEEE 802.15.4; fibre-optic networks; AWG; multichannel networks; industrial communications; embedded systems; Computer engineering; Datorteknik;

    Abstract : When designing architectures and protocols for data traffic requiring real-time services, one of the major design goals is to guarantee that traffic deadlines can be met. However, many real-time applications also have additional requirements such as high throughput, high reliability, or energy efficiency. READ MORE

  7. 10. Design and Detailed Analysis of Turbomachinery Blades using Truncated Domains

    Author : Gonzalo Montero Villar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Evolutionary algorithms; Phase-lagged boundary conditions; Sliding grid; LODI; Stochastic optimization; Synthetic turbulence; CFD; Chorochronic;

    Abstract : With the continuous growth in air traffic that we are seeing nowadays comes an increase in the requirements needed to be satisfied by an aircraft for it to be certified to fly. These stricter regulations affect aspects such as CO2 emissions, sound pollution and so on, pushing manufacturers to aim for lighter, more efficient, more robust designs. READ MORE
