  1. 1. En Social Nätverksanalys av ett Hackerforum

    Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Albin Erlander; [2024]
    Nyckelord :Social Nätverksanalys; SNA; Hackerforum; Cyberhotsunderrättelser; Law and Political Science;

    Sammanfattning : The spread and societal dependence on the internet has increased the threat posed by criminal hackers. While often thought of as lone wolfs, hackers often exist in communities and a widespread subculture. LÄS MER

  3. 2. Identifying Graph Characteristics in Growing Vascular Networks

    Master-uppsats, Uppsala universitet/Tillämpad beräkningsvetenskap

    Författare :Christopher Finn Plummer; [2024]
    Nyckelord :Anigogenesis; Vascular Networks; Network Science;

    Sammanfattning : One of the ways that a vascular network grows is through the process of angiogenesis, wherebya new blood vessel forms as a branch from an existing vessel towards an area which isstimulating vascular growth. Due to the demands for nutrients and waste transport, growingtumour cells will access the surrounding vascular network by inducing angiogenesis. LÄS MER

  4. 3. Den digitala tidsålderns Hermes: Sociala medierplattformar och dess inverkan på reflexiv kontroll

    Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Emelie Markianos; [2024]
    Nyckelord :Reflexive control; social media platforms; Facebook; TikTok; communication; influence operations; Law and Political Science;

    Sammanfattning : This thesis has examined how reflexive messages can be influenced by embedded functions on social media platforms. The purpose of the study has been to understand if, and how social media platforms can facilitate various kinds of reflexive control through their embedded functions. LÄS MER

  5. 4. An Empirical Survey of Bandits in an Industrial Recommender System Setting

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Tobias Schwarz; Johan Brandby; [2023-09-21]
    Nyckelord :computer science; industrial application; machine learning; reinforcement learning; multi-armed bandits; MAB; contextual multi-armed bandits; survey; batch learning;

    Sammanfattning : In this thesis, the effects of incorporating unstructured data—images in the wild—in contextual multi-armed bandits are investigated, when used within a recommender system setting, which focuses on picture-based content suggestion. The idea is to employ image features, extracted by a pre-trained convolutional neural network, and study the resulting bandit behaviors when including respective excluding this information in the typical context creation, which normally relies on structured data sources—such as metadata.

  7. 5. Evaluation and Optimization of LTE-V2X Mode 4 under Aperiodic Messages of Variable Size

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Md Mamunur Rashid; [2023]
    Nyckelord :LTE-V2X; aperiodic; variable size; CAM; Technology and Engineering;

    Sammanfattning : Vehicular networks connect vehicles for improved road safety and efficiency with the assistance of wireless information exchange. Vehicular networks are based on the frequent broadcast of awareness messages referred to as CAM (Cooperative Awareness Messages) or BSM (Basic Safety Message) in the ETSI and SAE standards, respectively.
