  2. 1. Towards a Scalable and Low-Latency Softwarized Mobile Packet Core Network

    Author : Van-Giang Nguyen; Anna Brunström; Karl-Johan Grinnemo; Javid Taheri; Christian Esteve Rothenberg; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mobile Packet Core; Evolved Packet Core; 5G; SDN; NFV; Scalability; Control Plane; User Plane; MME; UPF; VPP; Load Balancing; Auto-Scaling; Time-Critical; Low-Latency; Smart Grid; GOOSE; Computer Science; Datavetenskap;

    Abstract : The mobile packet core – a central part of the overall mobile cellular network – has a long history of evolution. Through the years, its architecture has been drastically changed to meet the demand coming from the fast growth in the number of devices as well as the introduction of new types of applications and services.

  4. 2. Stereoscopic Label Placement : Reducing Distraction and Ambiguity in Visually Cluttered Displays

    Author : Stephen D. Peterson; Anders Ynnerman; Matthew Cooper; John Wann; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Label placement; user interfaces; stereoscopic displays; augmented reality; virtual reality; visual clutter; Computer science; Datavetenskap;

    Abstract : With increasing information density and complexity, computer displays may become visually cluttered, adversely affecting overall usability. Text labels can significantly add to visual clutter in graphical user interfaces, but are generally kept legible through specific label placement algorithms that seek visual separation of labels and other objects in the 2D view plane.

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

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

    Abstract : 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).

  6. 4. Multiple Antenna Terminals in Realistic Environments - A Composite Channel Modeling Approach

    Author : Fredrik Harrysson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Channel model; MIMO; multiple antennas terminal; propagation; user interaction; vehicular channel; diversity; spatial multiplexing; channel measurement;

    Abstract : For evaluation of specific antenna arrangements in wireless communication systems we need physical channel models that take into account also the directional domain of the propagation channel. In this thesis we investigate, validate and propose a practical approach to wireless channel modeling and, particularly, to mobile communication systems. READ MORE

  7. 5. Experimental characterization and numerical modeling of compression perpendicular to the grain in wood and cross-laminated timber

    Author : Shaheda T. Akter; Thomas K. Bader; Erik Serrano; Jan Oscarsson; Reinhard Brandner; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rolling shear; biaxial testing; stress combination; RT-plane; moisture influence; rolling shear creep; digital image correlation; strain field; CLT connection; rotational stiffness; rullskjuvning; biaxiell undersökning; spänningskombination; RT-plan; fuktpåverkan; krypning vid rullskjuving; digital bildkorrelation; töjningsfält; KLTanslutning; rotationsstyvhet; Byggteknik; Civil engineering;

    Abstract : Compression perpendicular to the grain (CPG) of wood is a typical loading situation in timber structures. It has been an extensively studied research topic for decades, due to the highly ductile behavior of wood under such loading, the large variations in mechanical properties, and the relevance of these properties in structural design.
