  1. 6. Improving a Background Model for Tracking and Classification of Objects in LiDAR 3D Point Clouds

    University essay from Lunds universitet/Matematik LTH

    Author : Seamus Doyle; Gustav Nilsson; [2022]
    Keywords : LiDAR; Semantic Segmentation; Neural Networks; RandLA-NET; 3D Point Cloud; Gaussian Process Regression; Robust Locally Weighted Regression; CARLA; Ground Model; Technology and Engineering;

    Abstract : This thesis studied methods of improving a background model for a data processing pipeline of LiDAR point clouds. For this, two main approaches were evaluated. The first was to implement and compare three different models for detecting ground in a point cloud. These were based on more classical modeling approaches. READ MORE

  3. 7. Hybrid Wireless Positioning

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Phalguni Nagendra; Marco Vihelmo Velapatino Gamarra; [2022]
    Keywords : Technology and Engineering;

    Abstract : Numerous location-based services (LBS) have evolved because of the fast development of mobile Internet for use in commerce, entertainment, security, and other areas. All of these need a precise real-time location-based service with smooth indoor- outdoor transition in highly populated areas. READ MORE

  4. 8. Extended and Unscented Kalman Filtering for Estimating Friction and Clamping Force in Threaded Fasteners

    University essay from Uppsala universitet/Signaler och system

    Author : Mohammad Al-Barghouthi; [2021]
    Keywords : Estimation Theory; Extended Kalman Filter; EKF; Unscented Kalman Filter; UKF; Observability; Friction; Clamping Force; Tightening; Torque Controlled; Bolt; Threaded Fasteners;

    Abstract : Threaded fasteners tend to break and loosen when exposed to cyclic loads or potent temperature variations. Additionally, if the joint is held tightly to the structure, distortion will occur under thermal expansion issues. READ MORE

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

    University essay from 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.

  6. 10. Traffic State Estimation for Signalized Intersections : A Combined Gaussian Process Bayesian Filter Approach

    University essay from KTH/Transportplanering

    Author : Michael Sederlin; [2020]
    Keywords : Traffic State Estimation; Traffic Flow modelling; Gaussian Processes; Bayesian Filtering; Kalman Filter; Traffic Signals; Intersection; Non-parametric;

    Abstract : Traffic State Estimation (TSE) is a vital component in traffic control which requires an accurate viewof the current traffic situation. Since there is no full sensor coverage and the collected measurementsare inflicted with random noise, statistical estimation techniques are necessary to accomplish this. READ MORE
