  1. 1. Predicting the Impact of Supply Chain Disruptions Using Statistical Analysis and Machine Learning

    University essay from KTH/Matematisk statistik

    Author : Hannes Andersson; John Sjöberg; [2023]
    Keywords : Supply chain disruption; SMOTE; feature engineering; machine learning; random forest; statistics; applied mathematics; Störning i försörjningskedja; maskininlärning; matematik; statistik;

    Abstract : The dairy business is vulnerable to supply chain disruptions since large safety stocks to cover up losses are not always a viable option, therefore it is crucial to maintain a smooth supply chain to ensure stable delivery accuracies. Disruptions are unpredictable and hard to avoid in the supply chain, especially in cases where production errors cause lost production volume. READ MORE

  3. 2. Cross coupling in a two-axis control system for stabilized platforms

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

    Author : Bill Lavebratt; [2022]
    Keywords : MIMO; Modeling; Two-axis gimbal system; Decoupler; Inner loop disturbance compensation; Control theory.;

    Abstract : Inertial stabilized platforms consisting of a two-axis gimbal assembly are often modelled as two independent SISO systems, describing the dynamics of the elevation axis and the azimuth axis respectively. In reality the state of the elevation channel and the state of the azimuth channel affect each other. READ MORE

  4. 3. A Deep Learning Based Approach to Object Recognition from LiDAR Data Along Swedish Railroads

    University essay from KTH/Fastigheter och byggande

    Author : Egil Morast; [2022]
    Keywords : Deep learning; DGCNN; LiDAR; Object recognition; Railroad; Automatisation; Sweden; Point cloud; Djupinlärning; DGCNN; LiDAR; Objektigenkänning; Järnväg; Automatisering; Sverige; Punktmoln;

    Abstract : Malfunction in the overhead contact line system is a common cause of disturbances in the train traffic in Sweden. Due to the preventive methods being inefficient, the Swedish Transport Administration has stated the need to develop the railroad maintenance services and has identified Artificial Intelligence (AI) as an important tool for this undertaking.

  5. 4. Modeling and Simulation of a Remote Controlled Weapon Station

    University essay from KTH/Matematik (Avd.)

    Author : Mats Svalstedt; [2022]
    Keywords : Modeling; System identification; Nonlinear black-box; Remote controlled weapon station; Modellering; Systemidentifiering; Icke-linjär black-box; Fjärrmanövrerad vapenstation;

    Abstract : Understanding how a system behaves when exposed to different scenarios is key when improvingand developing complex structures. The amount of different approaches is immense and variesfrom case to case. READ MORE

  6. 5. Inverse Uncertainty Quantification for Sounding Rocket Dispersion

    University essay from KTH/Matematik (Avd.)

    Author : Tove Ågren; [2022]
    Keywords : Uncertainty quantification; Bayesian inference; Rocket dispersion; Neural networks; Markov Chain Monte Carlo.; Osäkerhetskvantifiering; Bayesiansk inferens; Raketspridning; Neurala nätverk; Markovkedje-Monte Carlo;

    Abstract : Sounding rocket impact points are subject to dispersion due to uncertainties in simulation model parameters and perturbations of the rocket trajectory during flight. Estimating the area of dispersion assumes that associated model uncertainties and magnitude of perturbations have already been inferred. READ MORE
