  1. 1. Machine Learning assisted gNodeB Data Link Layer Capacity Management

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Adam Axelsson; [2023]
    Keywords : machine learning; telecommunications; 5g; packet losses; pacing algorithm;

    Abstract : In the uplink direction of 5G New Radio, signals are sent between Ra-dio Units and Digital Units. The production of these signals is non-deterministic, leading to signals often being produced in bursts. Thesesignal bursts can lead to exceeding the Data Link Layer capacity, whichcauses packet losses. READ MORE

  2. 2. Quadratic sample entropy as a measure of burstiness : A study in how well Rényi entropy rate and quadratic sampleentropy can capture the presence of spikes in time-series data

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Kira Huselius Gylling; [2017]
    Keywords : ;

    Abstract : Requests to internet servers do not in general behave in a manner which can be easily modelled and forecast with typical time-series methods, but often have a significant presence of spikes in the data, a property we call “burstiness”. In this thesis we study various entropy measures and their properties for different distributions, both theoretically and via simulation, in order to better find out how these measures could be used to characterise the predictability and burstiness of time series.

  3. 3. Dynamic fMRI brain connectivity : A study of the brain’s large-scale network dynamics

    University essay from Umeå universitet/Institutionen för strålningsvetenskaper; Umeå universitet/Institutionen för fysik

    Author : Per Brantefors; [2016]
    Keywords : fMRI; dynamic functional connectivity; burst; burstiness; resting-state; temporal graph theory; networks; connectome; dynamic brain connectivity;

    Abstract : Approximately 20% of the body’s energy consumption is ongoingly consumed by the brain, where the main part is due to the neural activity, which is only increased slightly when doing a demanding task. This ongoingly neural activity are studied with the so called resting-state fMRI, which mean that the neural activity in the brain is measured for participants with no specific task. READ MORE

  4. 4. Finding seminal scientific publications with graph mining

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Martin Runelöv; [2015]
    Keywords : citation network; graph mining; network; seminal; centrality;

    Abstract : We investigate the applicability of network analysis to the problem of finding seminal publications in scientific publishing. In particular, we focus on the network measures betweenness centrality, the so-called backbone graph, and the burstiness of citations. READ MORE

  5. 5. Design and Implementation of AXI-based Network-on-Chip Systems for Flow Regulation

    University essay from

    Author : Jiayi Zhang; [2009]
    Keywords : ;

    Abstract : In Network-on-Chip (NoC), controlling Quality-of-Service is crucial in order to build predictable systems. In this project, we design and implement an AXI-based system on the Nostrum NoC, which features a 2D mesh topology and deflective routing. The main components we add to the Nostrum NoC are master and slave interfaces. READ MORE
