  1. 1. Semi-supervised anomaly detection in mask writer servo logs : An investigation of semi-supervised deep learning approaches for anomaly detection in servo logs of photomask writers

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Toomas Liiv; [2023]
    Keywords : anomaly detection; semi-supervision; HSC; DeepSAD; photomasks; anomalidetektion; semi-övervakad; HSC; DeepSAD; fotomasker;

    Abstract : Semi-supervised anomaly detection is the setting, where in addition to a set of nominal samples, predominantly normal, a small set of labeled anomalies is available at training. In contrast to supervised defect classification, these methods do not learn the anomaly class directly and should have better generalization capability as new kinds of anomalies are introduced at test time.

  2. 2. Empirical Verification of an Acoustic Estimation of a Rocket Engine : A Comparison Between Estimated and Measured Noise of a Rocket Engine

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Elina Arvidsson; [2022]
    Keywords : Esrange Space Centre; Flame deflector; Acoustic estimation; Liquid rocket engine; Rocket Factory Augsburg; Jet acoustics; Esrange Space Centre; Flammdeflektor; Akustisk estimering; vätskedriven raketmotor; Rocket Factory Augsburg; strömningsakustik;

    Abstract : The noise of a rocket engine is a complex and complicated phenomenon which has been studied for more than half a century [1]. There are many sources to this noise, but due to its great potential impact to the surrounding structures, including the vehicle itself, it is important to have a model to estimate the acoustic environment the engine produces.

  3. 3. The visibility of double neutron star binaries to LISA

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Anatole Storck; [2021]
    Keywords : gravitational waves; LISA; neutron stars; orbital simulations; Runge-Kutta method; Physics and Astronomy;

    Abstract : Double neutron star binaries (DNSBs) in the mHz gravitational wave (GW) regime are an important group of objects which the GW detector LISA will be able to observe. The detection and parametrization of these objects will help develop our current understanding of neutron star formation and evolution. READ MORE

  4. 4. VePMAD: A Vehicular Platoon Management Anomaly Detection System : A Case Study of Car-following Mode, Middle Join and Exit Maneuvers

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Weaam Bayaa; [2021]
    Keywords : MDS; GMMHMM; PMP; Machine Learning; Bayesian information Criterion BIC ; Platoon Behavior Recognition; MDS; GMMHMM; PMP; Maskininlärnings; BIC; Plutonbeteendeigenkänning;

    Abstract : Vehicle communication using sensors and wireless channels plays an important role to allow exchanging information. Adding more components to allow exchanging more information with infrastructure enhanced the capabilities of vehicles and enabled the rise of Cooperative Intelligent Transport Systems (C-ITS).

  5. 5. Cross-Country Faults in Resonant-Earthed Networks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gabriel Miguel Gomes Guerreiro; [2020]
    Keywords : Cross- country fault; resonant earthing; compensated network; MV network; distance protection; fault analysis; RTDS EMTDC.; dubbla jordfel; spoljordning; jordfelskompenserade elnät; mellanspänningsnät; distansskydd; reläskydd; RTDS EMTDC.;

    Abstract : Reliability requirements for power systems have been constantly increasing, as customers of electric power desire high power availability. In order to improve continuity of supply in medium voltage (MV) networks, utilities in many countries in Europe, North/South America and Oceania use resonant earthing and allow the operation of the network during a single phasetoearth fault for periods from several seconds up to several hours, since the earthfault current at the fault point in such systems is considerably reduced and is unlikely to damage equipment or create hazardous voltages for people or livestock.
