  1. 1. GPS-Free UAV Geo-Localization Using a Reference 3D Database

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Justus Karlsson; [2022]
    Keywords : Deep Learning; Machine Learning; ML; AI; UAV; GPS-Free; CNN; 3D CNN; GCNN; 3D Database; geolocalization; geo-localization; georegistration; Hidden Markov Model; HMM; satellite; satellite database; Batch-Hard; triplet loss; PyTorch Geometric;

    Abstract : The goal of this thesis has been global geolocalization using only visual input and a 3D database for reference. In recent years Convolutional Neural Networks (CNNs) have seen huge success in the task of classifying images. The flattened tensors at the final layers of a CNN can be viewed as vectors describing different input image features. READ MORE

  2. 2. Automatic Annotation of Speech: Exploring Boundaries within Forced Alignment for Swedish and Norwegian

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Klaudia Biczysko; [2022]
    Keywords : forced alignment; automatic speech recognition; ASR; natural language processing; under-resourced languages; Swedish; Norwegian; CTC segmentation; wav2vec2; kaldi; HTK; dynamic time warping;

    Abstract : In Automatic Speech Recognition, there is an extensive need for time-aligned data. Manual speech segmentation has been shown to be more laborious than manual transcription, especially when dealing with tens of hours of speech. READ MORE

  3. 3. HMM modelling for the spread of the SARS–CoV–2

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Martin Beneš; [2021]
    Keywords : ;

    Abstract : The aim of the project is to develop an HMM for the current spread of the SARS–CoV–2 virus. The HMM could be coupled with a SIR+ based compartmental model for the different types of statistics — confirmed cases, hospitalizations, deaths. READ MORE

  4. 4. Parasitic Tracking Mobile Wireless Networks

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

    Author : Bowen Xu; [2021]
    Keywords : Location privacy attack and evaluation; mobile network simulation; parasitic attacker; Heuristic LSTM;

    Abstract : Along with the growth and popularity of mobile networks, users enjoy more convenient connection and communication. However, exposure of user presence in mobile networks is becoming a major concern and motivated a plethora of LPPM Location Privacy Protection Mechanisms (LPPMs) have been proposed and analysed, notably considering powerful adversaries with rich data at their disposal, e.

  5. 5. Statistical Analysis and Modeling of the Behavioral Response to Humidity and Olfactory Cues by the Vinegar Fly Drosophila melanogaster

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Jonathan Lind; [2021]
    Keywords : Technology and Engineering;

    Abstract : Animals are impacted by the humidity of their surrounding environment, it affects their ability of thermoregulation, water retention and their overall well-being. For small insects the effects of the surrounding humidity is even more important as they have a limited water storage which depletes faster in a drier environment. READ MORE
