  1. 6. Core-collapse Supernovae : Theory vs. Observations

    Författare :Dennis Alp; Josefin Larsson; Sergey Tsygankov; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astrophysics; Supernovae; Fysik; Physics;

    Sammanfattning : A core-collapse supernova (CCSN) is an astronomical explosion that indicates the death of a massive star. The iron core of the star collapses into either a neutron star or a black hole while the rest of the material is expelled at high velocities. LÄS MER

  3. 7. Shear and Torsion Interaction in Prestressed Hollow Core Slabs

    Författare :Helén Broo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shear-torsion capacity; hollow core unit; shear and torsion interaction; non-linear finite element analyses; hollow core slab; precast prestressed concrete; hollow core floor;

    Sammanfattning : There are many applications in which hollow core units are subjected to combined torsion and shear, for example in floors supported on three edges and in floors with openings. The traditional calculation method for combined shear and torsion in hollow-core units adds stresses from various sources without taking into account deformations and compatibility within the unit or restraint at the boundaries.

  5. 9. Core Acquisition Management in Remanufacturing : Current Status and Modeling Techniques

    Författare :Shuoguo Wei; Ou Tang; Erik Sundin; Jan Olhager; Moritz Fleischmann; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Core acquisition; remanufacturing; closed-loop supply chain; quantitative modeling; return uncertainties;

    Sammanfattning : Remanufacturing is an important product recovery option that benefits our sustainable development. Cores, i.e. the used products/parts, are essential resources for remanufacturing. LÄS MER

  7. 10. Towards SDN/NFV-based Mobile Packet Core : Benefits, Challenges, and Potential Solutions

    Författare :Van-Giang Nguyen; Anna Brunström; Karl-Johan Grinnemo; Javid Taheri; Kurt Tutschku; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mobile packet core; evolved packet core; SDN; NFV; 5G; scalability; load balancing; control plane; open5Gcore; Computer Science; Datavetenskap;

    Sammanfattning : In mobile networks, the mobile core plays a crucial role in providing connectivity between mobile user devices and external packet data networks such as the Internet. Through the years, along with the dramatical changes in radio access networks, the mobile core has also been evolved from being a circuit-based analog telephony system in its first generation (1G) to become a purely packet-based network called the Evolved Packet Core (EPC) in the current generation (4G).
