  1. 1. Resource Allocation in Flexible-Grid Optical Networks with Nonlinear Interference

    Författare :Li Yan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaussian noise model; nonlinear interference; elastic optical networks; resource allocation; physical layer impairment; Flexible-grid optical network;

    Sammanfattning : As the backbone of modern communications, the optical networks are anticipated to provide higher data rate and flexibility to support the exponentially growing volume and heterogeneity of traffic requirements. Flexible-grid optical networks have been proposed to improve the utilization of spectrum resources. LÄS MER

  3. 2. Planning and Provisioning Strategies for Optical Core Networks

    Författare :Ajmal Muhammad; Robert Forchheimer; Lena Wosinska; Massimo Tornatore; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Optical communication networks are considered the main catalyst for the transformation of communication technology, and serve as the backbone of today's Internet. The inclusion of exciting technologies, such as, optical amplifiers, wavelength division multiplexing (WDM), and reconfigurable optical add/drop multiplexers (ROADM) in optical networks have made the cost of information transmission around the world negligible.

    Sammanfattning : Chitin is an important reinforcing component in load-bearing structures in many organisms such as insects and crustaceans (i.e. shrimps, lobsters, crabs etc.). LÄS MER

  5. 4. Micro-mechanical characterization and modeling of paper and paperboard

    Författare :August Brandberg; Artem Kulachenko; Sören Östlund; Carl Dahlberg; Rami Mansour; Ron Peerlings; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Fiber networks made of cellulose fibers from trees are used as information carriers (paper) and as packaging (paperboard). This thesis investigates the mechanical performance of paper and paperboard via micro-mechanical modeling and presents new methods for the mechanical characterization of the micro scale, necessary in such models.
