1. 1. Transformer-Based Multi-scale Technical Reports Analyser for Science Projects Cost Prediction

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

   Författare :Thomas Bouquet; [2023]
   Nyckelord :Natural Language Processing; Transformers; Deep Learning; Cost Prediction; Traitement Automatique du Langage; Transformers; Apprentissage Profond; Prédiction de coûts; Behandling av naturligt språk; Transformers; Djupinlärning; Kostnadsförutsägelser;

   Sammanfattning : Intrinsic value prediction is a Natural Language Processing (NLP) problem consisting in determining a numerical value contained implicitly and non-trivially in a text. In this project, we introduce the SWORDSMAN model (Sentence and Word-level Oracle for Research Documents by Semantic Multi-scale ANalysis), a deep neural network architecture based on transformers whose goal is to predict the cost of research projects from the analysis of their abstract.

3. 2. Optimization-Based Geometry Correction Of Blood Flow CFD Simulations Using 4D-Flow Data

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Fritiof Hegardt; [2022]
   Nyckelord :Technology and Engineering;

   Sammanfattning : 4D-flow is a powerful tool capable of capturing 3-dimensional, time-resolved flow measurements of blood flow in the body. Their current use is limited by resolution and scan times. A proposed solution is to use Simulation Based Imaging (SBI). LÄS MER

4. 3. A Fractional Step Zonal Model and Unstructured Mesh Generation Frame-work for Simulating Cabin Flows

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Sergi Tarroc Gil; [2021]
   Nyckelord :Zonal Model; Thermal Comfort; Fluid Simulation; Aircraft Cabin Design; NURBS; Morphing; Radial Basis Functions; Meshing; Co-located Mesh; Unstructured Mesh; Mesh Quality; Mesh Smoothing; Enlarged Orientation Theorem; Fractional Step Method; Boussinesq; Adam Bashforth; Helmholtz-Hodge Theorem; Rhie and Chow; Difference Schemes; Gradient Evaluation; Differential Heated Cavity; Driven Cavity; Draught Rate;

   Sammanfattning : The simulation of physical systems in the early stages of conceptual designs has shown to be a key factor for adequate decision making and avoiding big and expensive issues downstream in engineering projects. In the case of aircraft cabin design, taking into account the thermal comfort of the passengers as well as the proper air circulation and renovation can make this difference. LÄS MER

5. 4. Classification of Flying Qualities with Machine Learning Methods

   Master-uppsats, KTH/Flygdynamik

   Författare :Ola Isaksson; [2021]
   Nyckelord :Flying Qualities; Machine Learning; Flight Mechanics; Flygkvaliteter; Maskininlärning; Flygmekanik;

   Sammanfattning : The primary objective of this thesis is to evaluate the prospect of machine learning methods being used to classify flying qualities based on simulator data (with the focus being on pitch maneuvers). If critical flying qualities could be identified earlier in the verification process, they can be further invested in and focused on with less cost for design changes of the flight control system.

7. 5. Robust Design and Analysis of Automotive Collision Avoidance Algorithms

   Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

   Författare :Anders Sjöberg; [2019-06-17]
   Nyckelord :;

   Sammanfattning : Automotive collision avoidance systems help the driver to avoid or mitigate a collision. The main objective of this project is to find a methodology to improve the performance of Volvo’s automotive collision avoidance system by optimizing its configurable parameters. LÄS MER
