  3. 2. Simulation and Testing of a MU-MIMO Beamforming System

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Nazyar Mehdishishavan; Zonghan Wang; [2023]
    Keywords : Multi-User Multiple-Input Multiple-Output MU-MIMO ; Beamforming; Sounding Reference Signal SRS ; Reciprocity-based; Butler matrix; Advanced Antenna System AAS ; Technology and Engineering;

    Abstract : Multi-User Multiple-Input Multiple-Output (MU-MIMO) technology has become increasingly important in the field of wireless communication due to its ability to highly increase the capacity and efficiency of wireless networks [1]. Beamforming, as a technique used in MU-MIMO systems, improves network performance by improving signal quality and reducing interference. READ MORE

  4. 3. Assessing the Technological Landscape: ICT Tools and Technologies for Citizen-Government Communication and Their Level of Maturity

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Jean-Marc Kazadi Katembwe; [2023]
    Keywords : Systematic literature review; Transformational Government; ICT Tools and Technologies; Public values; Citizens issues; Maturity Level;

    Abstract : In today's rapidly evolving digital age, the relationship between citizens and government entities has undergone a transformative shift, primarily facilitated by Information and Communication Technologies (ICT). Transformational Government (T-Gov) is considered a technological innovation and a shift to a new entrepreneurial culture from inefficient, unaccountable bureaucracy generally observed within public organizations.

  5. 4. Minimum Cost Distributed Computing using Sparse Matrix Factorization

    University essay from KTH/Optimeringslära och systemteori

    Author : Seif Hussein; [2023]
    Keywords : Applied mathematics; optimization; convex optimization; matrix factorization; sparse matrix factorization; distributed computing; linearly separable distributed computing; ADMM; alternating direction method of multipliers; tillämpad matematik; optimering; konvex optimering; matrisfaktorisering; gles matrisfaktorisering; distribuerade beräkningar; admm; alternating direction method of multipliers;

    Abstract : Distributed computing is an approach where computationally heavy problems are broken down into more manageable sub-tasks, which can then be distributed across a number of different computers or servers, allowing for increased efficiency through parallelization. This thesis explores an established distributed computing setting, in which the computationally heavy task involves a number of users requesting a linearly separable function to be computed across several servers.

  6. 5. A Continuous-time ODE Framework to Centrality in Dynamic Networks

    University essay from Lunds universitet/Matematikcentrum; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Francisco Garcia Atienza; [2023]
    Keywords : networks; centrality; continuous-time; matrix logarithm; ode framework; katz; resolvent; Mathematics and Statistics;

    Abstract : The present study discusses and evaluates a novel continuous-time approach to network centrality, a fundamental concept in network analysis. Static methods based on discrete snapshots or time slices for measuring node interaction in networks that change over time do not fully capture the dynamical nature of network evolution. READ MORE
