  1. 1. Station-level demand prediction in bike-sharing systems through machine learning and deep learning methods

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

    Författare :Nikolaos Staikos; [2024]
    Nyckelord :Physical Geography; Ecosystem Analysis; Bike-sharing demand; Machine learning; Deep learning; Spatial regression; Graph Convolutional Neural Network; Multiple Linear Regression; Multilayer Perceptron Regressor; Support Vector Machine; Random Forest Regressor; Urban environment; Micro-mobility; Station planning; Geomatics; Earth and Environmental Sciences;

    Sammanfattning : Public Bike-Sharing systems have been employed in many cities around the globe. Shared bikes are an efficient and convenient means of transportation in advanced societies. Nonetheless, station planning and local bike-sharing network effectiveness can be challenging. LÄS MER

  3. 2. Förekomst och spridning av hänglavar från äldre skogar till unga tidigare avverkade områden i Västerbottens inland

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Emma Maksimova; [2023]
    Nyckelord :Lichens; Dispersal; Picea abies; Pinus sylvestris; Epiphytic; Hair lichens; Alectoria; Bryoria; Usnea;

    Sammanfattning : The Swedish forestry and the use of clearcutting models has resulted in great losses of older forests in Sweden, resulting in several species being affected negatively. Hair lichens are important organisms that are providing several ecological functions in forest ecosystems and are declining due to being associated with older forests with high continuity. LÄS MER

  4. 3. Point Cloud Registration using both Machine Learning and Non-learning Methods : with Data from a Photon-counting LIDAR Sensor

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Maja Boström; [2023]
    Nyckelord :Point Cloud Registration; Machine Learning; Photon-counting LIDAR; Iterative Closest Point;

    Sammanfattning : Point Cloud Registration with data measured from a photon-counting LIDAR sensor from a large distance (500 m - 1.5 km) is an expanding field. Data measuredfrom far is sparse and have low detail, which can make the registration processdifficult, and registering this type of data is fairly unexplored. LÄS MER

  5. 4. Analys av medianproblemetinom grafteori

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Linnéa Östlund; [2023]
    Nyckelord :;

    Sammanfattning : Medianproblemet innebär att, givet ett avståndsmått, hitta en permutationmed minsta totalavstånd till en mängd permutationer. Tidigare har fleraolika avståndsmått studerats och visat sig variera kraftigt i användbarhet. LÄS MER

  7. 5. How important are water sources to pastoralist movement in times of climate change? : A modelling approach.

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Max Louis Mischke; [2023]
    Nyckelord :Precipitation; Predictive Modelling; Mobility; Camp selection; Protected Area; Mongolia;

    Sammanfattning : Livestock grazing is an important part for the livelihood of a large part of the world’s population. While in some areas of the world water accessibility is often taken for granted, in arid regions this can be a limited resource. LÄS MER
