1. 1. Tuning an MPC-based Motion Planner using Imitation Learning

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :John Friberg; [2021]
   Nyckelord :;

   Sammanfattning : Model Predictive Control, MPC, is one of the most commonly used controllers today. They are well understood with a vastly researched theoretical background. One of the core strengths of MPC is that it is possible to provide safety guarantees for complex systems through the constraints enforced in the optimization problem. LÄS MER

3. 2. Generalizations of the Discrete Bak-Sneppen Model

   Kandidat-uppsats, Lunds universitet/Matematisk statistik

   Författare :John Jönsson; [2020]
   Nyckelord :discrete; Bak-Sneppen; model; generalized; probability; Markov; Mathematics and Statistics;

   Sammanfattning : Consider n vertices arranged in a circle where each vertex is given a fitness from {0,1}. At each discrete time step, one of the vertices with fitness equal to zero (unless there are none of those, then pick a vertex with fitness equal to one) is selected with equal probability. LÄS MER

4. 3. Lavinprognoser och maskininlärning : Att prediktera lavinprognoser med maskininlärning och väderdata

   Kandidat-uppsats, Uppsala universitet/Institutionen för informatik och media

   Författare :Gustav Pettersson; John Almqvist; [2019]

   Sammanfattning : Denna forskningsansats undersöker genomförbarheten i att prediktera lavinfara med hjälp av ma-skininlärning i form avXGBoostoch väderdata. Lavinprognoser och meterologisk vädermodelldata harsamlats in för de sex svenska fjällområden där Naturvårdsveket genomlavinprognoser.sepublicerar lavin-prognoser. LÄS MER

5. 4. Numerical and experimental dynamic analyses of the Vega Pedestrian bridge including seasonal effects

   Master-uppsats, KTH/Bro- och stålbyggnad

   Författare :John Hallak Neilson; [2019]
   Nyckelord :;

   Sammanfattning : As timber structures become increasingly relevant and sought after – since they enable improvements in building time while reducing a structure’s life cycle impacts – streamlining their design can have meaningful economic and environmental implications.For timber footbridges, its design is frequently governed by serviceability criteria linked to excessive vibrations.
