  1. 1. Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Duncan Jones; [2023]
    Nyckelord :Geography; Geographical Information Systems; GIS; Habitat Modelling; Harbour Porpoise; MaxEnt; Tidal Processes; Conservation; Earth and Environmental Sciences;

    Sammanfattning : Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall Abstract Unintentional by-catch in fishing gear is a significant cause of mortality of harbour porpoises in UK waters. Understanding the spatial distribution of harbour porpoises at fine scales and how this changes over time is essential when trying to understand where these lethal interactions might occur. LÄS MER

  3. 2. Anomaly Detection in Images and Videos Using Photo-Response Non-Uniformity

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Kerstin Söderqvist; [2021]
    Nyckelord :;

    Sammanfattning : When photos and videos are increasingly used as evidence material, it is of importance to know if these materials can be used as evidence material or if the risk of them being forged is impending. This thesis investigates methods for detecting anomalous regions in images and videos using photo-response non-uniformity -- a fixed-pattern sensor noise that can be estimated from photos or videos.

  4. 3. Singular Value Decomposition as a Method for Analyses and Forecasts of Financial Data

    Kandidat-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Axel Gustavsson; [2021]
    Nyckelord :Singular value decomposition; Technical analysis; Trading strategy; Finance; Business and Economics;

    Sammanfattning : This paper examines the sufficiency of a trading method based on singular value decomposition (SVD) of past stock prices. The SVD method is frequently used as a tool to reduce data noise, compress big-data, and analyse data components. Hence, the method is well suited to form a ground for a predictive tool of price developments. LÄS MER

  5. 4. Noise modelling for high-throughput super-resolution microscopy

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

    Författare :Xavier Casas Moreno; [2018]
    Nyckelord :;

    Sammanfattning : Super-resolution fluorescence microscopy is an emerging imaging fieldthat aims at breaking the di↵raction barrier of light based on state transitionin fluorescent molecules. Current challenges in the existing approachare to achieve large field of views, fast recordings and increasing the imagequality. LÄS MER

  7. 5. Suppression of impulsive noise in wireless communication

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Författare :qiaofeng cui; [2014]
    Nyckelord :GPS receiver; fastICA; BPSK; Impulsive Noise; Blind Signal Separation; Independent Component Analysis; ;

    Sammanfattning : This report intends to verify the possibility that the FastICA algorithm could be applied to the GPS system to eliminate the impulsive noise from the receiver end. As the impulsive noise is so unpredictable in its pattern and of great energy level to swallow the signal we need, traditional signal selection methods exhibit no much use in dealing with this problem.
