  1. 1. Design of Multi-layer Telecommunication Networks: Fairness, Resilience, and Load Balancing

    Författare :Eligijus Kubilinskas; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; network design; multi-layer networks; fairness; resilience; telecommunications; load balancing; optimization;

    Sammanfattning : Migration to Next Generation Internet architectures poses new challenges for network operators in planning core networks and calls for efficient network planning and optimization tools. Optimization models underlying such tools are developed in this thesis. LÄS MER

  3. 2. Multi-Layer Fault Tolerance for Distributed Real-Time Systems

    Författare :Raul Barbosa; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis addresses issues in building fault-tolerant distributed real-time systems. Such systems are increasingly deployed in automotive and avionics applications. We focus on the design and validation of fault tolerance mechanisms. From the design viewpoint, we develop the notion of multi-layer fault tolerance. LÄS MER

  4. 3. Phenomena in wire based multi-layer laser welding and hybrid deposition

    Författare :Jonas Näsström; Alexander Kaplan; Frank Brueckner; Sven Bengtsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsutveckling; Manufacturing Systems Engineering;

    Sammanfattning : Several laser materials processing technologies using metal wire addition have been researched during the last decades. Especially in the field of joining, as well as in the field of Additive Manufacturing (AM), multiple major benefits have been reached, e.g. higher welding speeds and lower heat input. LÄS MER

  5. 4. Computational Road Mechanics - with Emphasis on FE-analysis of Rutting

    Författare :Johan Olsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear FEM; multi-layer structure; asphalt concrete; road design; material models; unbound material;

    Sammanfattning : A road is a very complex structure in which a large number of different structural phenomena occur simultaneously that effects its expected lifetime. The structure itself is of a multi-layer type, in which the different layers consist of materials that exhibit vastly different physical behaviors when subjected to various kinds of loads. LÄS MER

  7. 5. On core and bi-layered all-ceramic fixed dental prostheses, design and mechanical properties : studies on stabilized zirconiumdioxide

    Författare :Deyar Mahmood Jallal Hadi; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Y-TZP; Zirconia; All-ceramic FDPs; connector design; radius; state-of-the-art; CAD CAM; multi-layer technique; veneering ceramic; split-file; over-pressing; dental porcelain; MECHANICAL PROPERTIES;

    Sammanfattning : Loss of teeth can affect a person’s self-esteem, social life, appearance and oral function. Reconstruction of a missing tooth has scientifically been shown to increase self-esteem and quality of life and to maintain oral function. For many patients a fixed dental prostheses (FDP) is preferred, either tooth- or implant-supported. LÄS MER
