  1. 1. Simulating Mobility of Large Population using Mobile Application Data

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Mattias Rydström; Diana Salim; [2024-01-23]
    Keywords : Human mobility; mobile application data; synthesize activity plans;

    Abstract : Understanding people’s travel patterns and knowing the frequency of their travel activities provide important insights for effective transport management and infrastructure planning. While traditional travel surveys have historically contributed to this valuable information, they come with shortcomings such as being expensive to collect, easily outdated, and having short time coverage.

  3. 2. 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

  4. 3. Towards Deep Learning Accelerated Sparse Bayesian Frequency Estimation

    University essay from Lunds universitet/Matematisk statistik

    Author : Mika Persson; [2022]
    Keywords : Bayesian Statistics; Deep Learning; Frequency Estimation; Generative Adversarial Networks; Artificial Neural Networks; Statistical Modelling; Mathematics and Statistics;

    Abstract : The Discrete Fourier Transform is the simplest way to obtain the spectrum of a discrete complex signal. This thesis concerns the case when the signal is known to contain a small (unknown) number of frequencies, not limited to the discrete Fourier frequencies, embedded in complex Gaussian noise.

  5. 4. A study of Locations for Mobile Hospitals in Dalarna

    University essay from Högskolan Dalarna/Mikrodataanalys

    Author : Samhita Giriraj; [2020]
    Keywords : Mobile Hospital; Analytic Hierarchical Process; Weighted Overlay; Location Allocation; Travel Distance;

    Abstract : Due to growing population over the past decades, settlements are scattered in sparse as well as dense clusters across Dalarna County. However, irrespective of any physical, social or economic conditions, free public health care must be available at a minimum and equal distance of travel for all citizens of a region. READ MORE

  6. 5. Physically Inspired Optimization

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Emmanuel-Roosevelt D Costa; [2020]
    Keywords : Optimization; Particle Swarm Optimization; PSO; Levenberg-Marquardt algorithm; Gradient descent algorithm; Gauss-Newton algorithm; Linear Least Squares; System of Springs; Physics and Astronomy;

    Abstract : Optimization is the study of finding the best solution for a problem. The applications of this field ranges from finding the best routes for travelling to finding the ground state of physical systems. READ MORE
