  1. 1. Data-driven Interpolation Methods Applied to Antenna System Responses : Implementation of and Benchmarking

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Lucas Åkerstedt; [2023]
    Nyckelord :Model Order Reduction; Loewner Framework; State-space Representation; Nevanlinna-Pick Interpolation; Vector Fitting; Cauchy interpolation; Antenna System Responses; Benchmarking; MoM; Data-driven; Interpolation; Modelordningsreducering; Loewner Ramverk; Tillståndsrepresentation; NevanlinnaPick Interpolering; Vector Fitting; Cauchy Interpolering; Antennsystemsvar; Prestandajämförelse; MoM; Datadriven; Interpolering;

    Sammanfattning : With the advances in the telecommunications industry, there is a need to solve the in-band full-duplex (IBFD) problem for antenna systems. One premise for solving the IBFD problem is to have strong isolation between transmitter and receiver antennas in an antenna system. LÄS MER

  3. 2. Predicting Reactor Instability Using Neural Networks

    Kandidat-uppsats, KTH/Fysik

    Författare :Hilborn Hubert; [2022]
    Nyckelord :Boiling Water Reactors; Density Wave Instability; Multi-Layer Perceptron; Support Vector Regression; Kernel-Ridge Regression;

    Sammanfattning : The study of the instabilities in boiling water reactors is of significant importance to the safety withwhich they can be operated, as they can cause damage to the reactor posing risks to both equipmentand personnel. The instabilities that concern this paper are progressive growths in the oscillatingpower of boiling-water reactors. LÄS MER

  4. 3. LSTM Feature Engineering Through Time Series Similarity Embedding

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Sebastian Bångerius; [2022]
    Nyckelord :Embedding; time series; LSTM; feature engineering; DTW; correlation; prediction;

    Sammanfattning : Time series prediction has many applications. In cases with simultaneous series (like measurements of weather from multiple stations, or multiple stocks on the stock market)it is not unlikely that these series from different measurement origins behave similarly, or respond to the same contextual signals.

  5. 4. Road-traffic accident prediction model : Predicting the Number of Casualties

    Master-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

    Författare :Jemal Ahmed Andeta; [2021]
    Nyckelord :Road traffic accident; Accident Casualties; Gradient Boosting; Extreme Learning Machines; Prediction Interval;

    Sammanfattning : Efficient and effective road traffic prediction and management techniques are crucial in intelligent transportation systems. It can positively influence road advancement, safety enhancement, regulation formulation, and route planning to save living things in advance from road traffic accidents. LÄS MER

  7. 5. Detection of in-plane orbital manoeuvres from a catalogue of geostationary objects

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Phuong Linh Ngo; [2020]
    Nyckelord :manoeuvre detection; geostationary orbit; perturbations; filters; Two-line elements; station keeping;

    Sammanfattning : The number of man-made space objects is dramatically growing nowadays. The continuous monitoring and studying of these objects are necessary to keep their number under control and ensure safe space operations. LÄS MER
