  2. 1. Anypath Routing for Reducing Latency in Multi-Channel Wireless Mesh Networks

    Author : Andreas Lavén; Anna Brunstrom; Andreas Kassler; Björn Landfeldt; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wireless Mesh Networks; Anypath Routing; Forwarding; VoIP; Computer Science; Datavetenskap;

    Abstract : Increasing capacity in wireless mesh networks can be achieved by using multiple channels and radios. By using different channels, two nodes can send packets at the same time without interfering with each other. To utilize diversity of available frequency, a channel assignment scheme is required.

  4. 2. History Reduction Techniques for Simulation of Additive Manufacturing and Physically based Material Modeling

    Author : Andreas Malmelöv; Andreas Lundbäck; Bijish Babu; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära;

    Abstract : In this thesis, finite element (FE) simulations of additive manufacturing (AM) and physically based material modeling are presented. AM is a process where the component is built layer-wise. READ MORE

  5. 3. Simulation of additive manufacturing using a mechanism based plasticity model

    Author : Andreas Malmelöv; Andreas Lundbäck; Mathias Wallin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Residual stress; Material model; Alloy 625; Alloy 718; deformations; Finite Element Method; synchrotron X-ray diffraction; Solid Mechanics; Hållfasthetslära;

    Abstract : This thesis presents finite element (FE) simulations of additive manufacturing (AM) and physically based material modeling of alloy 625 and alloy 718. In recent years, there has been an increasing interest in AM and there has been a dramatic increase in publications in the field. READ MORE

  6. 4. Proof-related reasoning in upper secondary mathematics textbooks : Characteristics, comparisons, and conceptualizations

    Author : Andreas Bergwall; Andreas Ryve; Kimmo Eriksson; Kristina Juter; Mälardalens högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics textbook; upper secondary school; proof-related reasoning; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Abstract : Proofs and proving are difficult to learn and difficult to teach. A common problem is that many students use specific examples as evidence for general statements. Difficulties with proofs are also part of the transition problems that exist between secondary and tertiary schooling in mathematics. READ MORE

  7. 5. Static Execution Time Analysis of Parallel Systems

    Author : Andreas Gustavsson; Björn Lisper; Jan Gustafsson; Andreas Ermedahl; David Broman; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; WCET analysis; parallel systems; multi-core; multicore; threaded programming language; Computer Science; datavetenskap;

    Abstract : The past trend of increasing processor throughput by increasing the clock frequency and the instruction level parallelism is no longer feasible due to extensive power consumption and heat dissipation. Therefore, the current trend in computer hardware design is to expose explicit parallelism to the software level. READ MORE
