  1. 1. Implementation of Spectrum Analysis Functionality for IQ-Signal.

    University essay from Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

    Author : Gedion Biredaw Anbessa; [2020]
    Keywords : RF Measurement Techniques; Spectrum Analyzer; Synthetic Spectrum Analysis; Synthetic Instrument; Signal Processing; Vector Signal Analyzer; IQ-signal;

    Abstract : The spectrum analyzer is a standard tool used to measure signals in the frequency domain. Traditional spectrum analyzers are based on sweeping a local oscillator and using this to mix signals down to an intermediate frequency (IF) and, subsequently filter them with a filter of settable characteristics, called the Resolution Bandwidth (RBW).

  2. 2. Detecting bark beetle damage with Sentinel-2 multi-temporal data in Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Shuo Yang; [2019]
    Keywords : Physical Geography and Ecosystem Analysis; Remote Sensing; Bark Beetle; Insect Detection; Sentinel-2; Forest Health; Maximum Likelihood; Random Forest; Spectral Signature; Vegetation Indices; Earth and Environmental Sciences;

    Abstract : The European spruce bark beetle is considered as one of the most destructive forest insects to Norway spruce trees in Europe. Climate change may increase the frequency and intensity of bark beetle outbreaks. It is therefore of vital importance to detect the bark beetle outbreaks and take it under control to prevent further damages. READ MORE

  3. 3. Pixel-Based Algorithms for DataAnalysis in Digital Pathology : Data Analysis of the BOMI2 Redox Dataset,A Step Away From Cell Segmentation Dependant Methods

    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

    Author : Michael Wallgren Fjellander; [2019]
    Keywords : Digital Pathology; Cell Segmentation; Algorithms; Image Analysis; Cancer; Pixel-based Methods; Knee Point;

    Abstract : In this project report a novel pixel-based approach to digital pathology is proposed. The algorithm directly decides the class of single pixels in an image without needing the larger context of neighbouring pixels. READ MORE

  4. 4. Investigation Of Source Parameters Of Earthquakes In Northern Sweden

    University essay from Uppsala universitet/Geofysik

    Author : María González-Caneda; [2019]
    Keywords : spectral analysis; earthquake source observations; ω-2 source model; moment magnitude; local magnitude; Northern Sweden seismicity.;

    Abstract : By studying the frequency domain of seismic signals generated by earthquakes, the source parameters can be recovered, i.e., the seismic moment (M0) and the stress drop (Δσ). READ MORE

  5. 5. Temporally Stable Clusters of Movie Series : A Machine Learning Approach to Content Segmentation

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

    Author : Patrick Miller Ugalde; [2019]
    Keywords : ;

    Abstract : Clustering techniques have been shown to provide insight in various domains and applications. Adaptive evolutionary spectral clustering is a state-of-the-art method to obtain temporally stable clustering results from time-stamped data. READ MORE
