  1. 1. Predicting Patent Data using Wavelet Regression and Bayesian Machine Learning

    University essay from KTH/Matematik (Avd.)

    Author : Mattias Martinsen; [2023]
    Keywords : Wavelet; Regression; Bayesian network; Prediction; Patent; Machine Learning; Wavelet; Regression; Bayesiskt nätverk; Predicering; Patent; Maskininlärning;

    Abstract : Patents are a fundamental part of scientific and engineering work, ensuringprotection of inventions owned by individuals or organizations. Patents areusually made public 18 months after being filed to a patent office, whichmeans that current publicly available patent data only provides informationabout the past. READ MORE

  3. 2. Design of a UAV-based radio receiver for avalanche beacon detection using software defined radio and signal processing

    University essay from Uppsala universitet/Signaler och System

    Author : Richard Hedlund; [2019]
    Keywords : Signal processing; Software Defined Radio; Avalanche; Beacon; Antenna; SDR; DSP; Signalbehandling; Mjuvarudefinierad Radio; Lavin; Lavinsändare; Antenn; SDR; DSP;

    Abstract : A fully functional proof of concept radio receiver for detecting avalanche beacons atthe frequency 457 kHz was constructed in the work of this master thesis. The radioreceiver is intended to be mounted on an unmanned aerial vehicle (UAV or drone)and used to aid the mountain rescue teams by reducing the rescue time in findingavalanche victims carrying a transmitting beacon.

  6. 5. Implementation of the LMS Algorithm for Noise Cancellation on Speech Using the ARM LPC2378 Processor.

    University essay from Matematiska och systemtekniska institutionen

    Author : Cesar Augusto Azurdia Meza; Yaqub Jon Mohamadi; [2009]
    Keywords : Signal Processing; Digital Filters; LMS Algorithm; Noise Cancellation; Digital Processors;

    Abstract : On this thesis project, the LMS algorithm has been applied for speech noise filteringand different behaviors were tested under different circumstances by using Matlabsimulations and the LPC2378 ARM Processor, which does the task of filtering in realtime. The thesis project is divided into two parts: the theoretical and practical part. READ MORE
