  1. 1. A comparison of a Lazy PageRank and variants for common graph structures

    Magister-uppsats, Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Författare :Barkat Aziz Ali; [2018]
    Nyckelord :Lazy PageRank; graph structures;

    Sammanfattning : The thesis first reviews the mathematics behind the Google’s PageRank, which is the state-of-the-art webpage ranking algorithm. The main focus of the thesis is on exploring a lazy PageRank and variants, related to a random walk, and by realizing that, they can be computed using the very same algorithm, find lazy PageRank and variants' expressions for some common graph structures, for example, a line-graph, a complete-graph, a complete-bipartite graph including a star graph, and try to get some understanding of the behavior of the PageRank, when a network evolves, for example either by a contraction or an expansion of graphs’ nodes or links.

  3. 2. A Joint Subcarrier/Power allocation Scheme for OFDMA-based Cellular Networks

    Master-uppsats, Kommunikations- och transportsystem; Tekniska högskolan

    Författare :Aamir Abdul Aziz Hasan Ali; Muhammad Adil Shahzad; [2012]
    Nyckelord :;

    Sammanfattning : The assignment of this master thesis consists of initiating power, subcarrier allocation in a dynamic FFR based scheme designed for multi-cell OFDMA networks and to enhance the throughput of all center users in bandwidth hungry borrower cells (overloaded cells) which was previously degraded by original FFR3 scheme as a result of partitioning of system bandwidth into center and edge bands respectively. The method uses band borrowing to compensate center user’s throughput loss in a semi and fully overloaded system. LÄS MER

  4. 3. Describing tree size diversity

    Magister-uppsats, SLU/Dept. of Forest Resource Management

    Författare :Abdul Aziz Ali; [1997]
    Nyckelord :Tree; Size; Diversity;

    Sammanfattning : Management based modifications of forest structure require a precise description of the forest state both before and after a silvicultural interference. While the average values of variables such as diameter, height and basal area provide useful descriptions of the forest state, these variables do not give information about the structural variety of the forest on a tree to tree basis.
