  1. 1. Cropland and tree cover mapping using Sentinel-2 data in an agroforestry landscape, Burkina Faso

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Ntandokazi Masimula; [2020-06-29]
    Keywords : Sentinel-2; Cropland mask; Tree cover estimation; Burkina Faso; Agroforestry; Random Forest;

    Abstract : Sentinel-2, with high spatial resolution bands and increased number of spectral channels,has provided increased capabilities for vegetation mapping. Cropland masks withinheterogeneous areas such as the Sudano-Sahel zone have become useful for monitoringlandscapes. READ MORE

  2. 2. Modelling gross primary production in semi-arid regions: effects on carbon uptake of intensive agriculture in southern Kenya

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Malin Ahlbäck; [2020]
    Keywords : Physical Geography; Ecosystem Analysis; GPP; Africa; Kenya; Land cover changes; Cropland; Remote sensing; Sentinel-2; Earth and Environmental Sciences;

    Abstract : Background and aim: Gross primary production (GPP) is the largest global carbon (C) flux and an important component for counteracting anthropogenic CO2 emissions, understanding vegetation dynamics, and sustaining universal human standards. Africa plays a prominent role in the global C cycle, though our understanding of GPP dynamics is largely hampered by a paucity of ground-based observations. READ MORE

  3. 3. Evaluated density estimates of young forest stands using high resolution 2D imagery from UAV

    University essay from SLU/Dept. of Forest Resource Management

    Author : Victor Kingstad; [2020]
    Keywords : UAV; forestry; inventory; survey; cleaning; tending; PCT; pre com-mercial thinning;

    Abstract : After more than three decades of advanced technology and methods to evaluate young forest attributes, the forestry still prefers laborious field surveys in regenera-tion forests. Preceding studies have virtually all successfully identified the saplings, but the cost has outweighed the benefits or at least not yet convinced the companies to step away from the traditional field surveys; high-resolution photogrammetric point clouds and ALS-data can provide accurate estimations of the biophysical prop-erties but requires intense data processing.

  4. 4. A Comparison between Different Recommender System Approaches for a Book and an Author Recommender System

    University essay from Linköpings universitet/Interaktiva och kognitiva system; Linköpings universitet/Interaktiva och kognitiva system

    Author : Jesper Hedlund; Emma Nilsson Tengstrand; [2020]
    Keywords : Recommender System; Collaborative Filter; Matrix Factorization; Content-based Filter; Doc2Vec;

    Abstract : A recommender system is a popular tool used by companies to increase customer satisfaction and to increase revenue. Collaborative filtering and content-based filtering are the two most common approaches when implementing a recommender system, where the former provides recommendations based on user behaviour, and the latter uses the characteristics of the items that are recommended.

  5. 5. Dynamic prediction of repair costs in heavy-duty trucks

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Lakshidaa Saigiridharan; [2020]
    Keywords : Hurdle Gamma model; Hierarchical hurdle Gamma model; Generalized linear model GLM ; Supervised Machine Learning; feature selection; Akaike Information Criterion AIC ; prediction of repair costs; heavy-duty trucks; truck variants; operational features;

    Abstract : Pricing of repair and maintenance (R&M) contracts is one among the most important processes carried out at Scania. Predictions of repair costs at Scania are carried out using experience-based prediction methods which do not involve statistical methods for the computation of average repair costs for contracts terminated in the recent past.
