    Abstract : One of the goals pursued in the present research was to understand the nuclear phenomena (such as rotational bands, their backbending and termination, deformation, pairing correlations, etc.) using different views provided by different nuclear models. READ MORE

  4. 2. Microscopic Properties of Superdeformed Nuclei

    Author : Lennart B Karlsson; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; superdeformation; Nilsson-Strutinsky; modified oscillator potential; moments of inertia; transition energies; rotational bands; quadrupole moments; spin assignments; identical bands; additivity.; Mathematical and general theoretical physics; classical mechanics; relativity; quantum mechanics; kvantmekanik; klassisk mekanik; thermodynamics; Matematisk och allmän teoretisk fysik; termodynamik; relativitet; statistisk fysik; Fysicumarkivet A:1999:Karlsson;

    Abstract : Many high spin rotational bands in superdeformed nuclei have been found in the A ~ 140-150 region, but so far no linking transitions to known normal-deformed states have been found in these nuclei. Therefore, configuration and spin assignments have to be based on indirect spectroscopic information. READ MORE

  6. 4. Design of Reliable Communication Solutions for Wireless Sensor Networks : Managing Interference in Unlicensed Bands

    Author : Luca Stabellini; Jens Zander; Andreas Kassler; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Abstract : Recent surveys conducted in the context of industrial automation have outlined that reliability concerns represent today one of the major barriers to the diffusion of wireless communications for sensing and control applications: this limits the potential of wireless sensor networks and slows down the adoption of this new technology. Overcoming these limitations requires that awareness on the causes of unreliability and on the possible solutions to this problem is created. READ MORE

  7. 5. Investigations on the Formation of Defect Bands in Semi-Solid High Pressure Die Cast Aluminium-Silicon Alloys

    Author : Madeleine Law; Pär Jönsson; Christopher Hulme-Smith; Taishi Matsushita; Jessica Elfsberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Semi-Solid Metals; SSM; Al-Si Alloys; Defect bands; HPDC; Semisolida metaller; SSM; Al-Si-Alloys; defektband; HPDC; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : High-pressure die casting of semi-solid aluminium-silicon alloys is used in the automotive industry to manufacture components, like housings, brackets, and bars. It is commonly known that during high-pressure die casting, defect bands may be created that follow the contour of the component surface. These bands consist mainly of a eutectic phase. READ MORE
