  1. 1. Visualization Of Cyber Threats : Visualization To Leading Operatives During Cybersecurity exercises

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Författare :Gustaf Tysk; [2023]
    Nyckelord :Situational Awareness; Common operational picture; Perception; Comprehension; Projection; Cybersecurity; Defense; Visualization;

    Sammanfattning : The increasing dependence on digital infrastructure leaves individuals, societies and even nations vulnerable in the case of a cyberattack. To prepare for threats and attacks, cyberattacks be simulated in environments called cyber ranges. CYBER RANGE AND TRAINING ENVIRONMENT (CRATE), Sweden's cyber range, is an example of such an environment. LÄS MER

  3. 2. Reusage classification of damaged Paper Cores using Supervised Machine Learning

    M1-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Max Elofsson; Victor Larsson; [2023]
    Nyckelord :Machine Learning; Supervised Learning; classification; 3D sensor; TriSpector1008; SICK; paper core; paper mill; KNN; Support Vector Machine; Decision Trees; Random Forest; Maskininlärning; klassificering; papperskärna; pappersbruk;

    Sammanfattning : This paper consists of a project exploring the possibility to assess paper code reusability by measuring chuck damages utilizing a 3D sensor and usingMachine Learning to classify reusage. The paper cores are part of a rolling/unrolling system at a paper mill whereas a chuck is used to slow and eventually stop the revolving paper core, which creates damages that at a certain point is too grave for reuse.

  4. 3. Numerical Simulation of the Generalized Modified Benjamin-Bona-Mahony Equation Using SBP-SAT in Time

    Kandidat-uppsats, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Vilma Kjelldahl; [2023]
    Nyckelord :Benjamin-Bona-Mahony equation; non-linear; initial boundary value problem; summation-by-parts; simultaneous-approximation-term; time integration; simulation;

    Sammanfattning : This paper describes simulations of the generalized modified Benjamin-Bona-Mahony (BBM) equation, using finite difference methods (FDM). Well-posed boundary conditions (BCs) as well as stable semi-discrete approximations are derived using summations-by-parts (SBP) operators combined with the projection method. LÄS MER

  5. 4. Towards Large Scale Façade Parsing: A Deep Learning Pipeline Using Mask R-CNN

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

    Författare :MOLA AYENEW; [2022-04-27]
    Nyckelord :pipeline; semi-automated; building facade; parsing; panorama imagery; Google Street view; mapillary; Mask R-CNN; deep learning; inference; rectilinear projection;

    Sammanfattning : This thesis tries to find a methodology that create a working pipeline for building facade parsing, which allows to access large scale panorama imagery from Google Street View (GSV) and implement on deep learning models. We propose a semiautomated pipeline that integrates multiple systems for large-scale building facade parsing. LÄS MER

  7. 5. Detective Quantum Efficiency in the Image Domain

    Master-uppsats, KTH/Fysik

    Författare :Per Lundhammar; [2022]
    Nyckelord :detective quantum efficiency; linear systems theory; projection domain; image domain; x-ray imaging; detektiv kvanteffektivitet; linjär-systemteori; projektionsdomän; bilddomän; röntgenavbildning;

    Sammanfattning : We investigate the signal and noise transform characteristics from the projection domain to the image domain in a linear systems theory framework and predictions of the DQE within this framework are made. A simulation study of a photon counting silicon detector is made from which the energy information is used in order to produce synthetic monoenergetic images. LÄS MER
