1. 31. Deep learning for non-intrusive sensing in turbulence with passive scalars

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Arivazhagan Geetha Balasubramanian; [2021]
   Keywords : Turbulent boundary layer; passive scalar; direct numerical simulation; Prandtl number; Machine learning; convolutional neural network; Turbulent gränsskikt; passiv skalär; direkt numerisk simulering; Prandtl-nummer; maskininlärning; faltningsneurala nätverk;

   Abstract : The near-wall modelling of turbulent flows has been an active field of research due to the computational cost associated with the direct numerical simulations of such flow, which are characterized by a wide range of length and time scales. With the recent advancements in technological capabilities, the availability of high-fidelity data has enabled the construction of data-driven approaches to model turbulence. READ MORE

3. 32. Inverse Uncertainty Quantification using deterministic sampling : An intercomparison between different IUQ methods

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Hjalmar Andersson; [2021]
   Keywords : Inverse Uncertainty Quantification; Model calibration; Unscented transform; Deterministic sampling;

   Abstract : In this thesis, two novel methods for Inverse Uncertainty Quantification are benchmarked against the more established methods of Monte Carlo sampling of output parameters(MC) and Maximum Likelihood Estimation (MLE). Inverse Uncertainty Quantification (IUQ) is the process of how to best estimate the values of the input parameters in a simulation, and the uncertainty of said estimation, given a measurement of the output parameters.

4. 33. Planning Method for a Reversing Single Joint Tractor-Trailer System

   University essay from Linköpings universitet/Fordonssystem

   Author : Ofa Ismail; [2021]
   Keywords : Motion planning; Local planing method; Reversing tractor-trailer; RRT; Rapidly-exploring Random Tree;

   Abstract : This thesis investigates the design of a local planning method for a reversing single joint tractor-trailer system that can be used in a sampling-based motion planner. The motion planner used is a Rapidly-exploring Random Tree (RRT) developed by Scania. READ MORE

5. 34. Water quality and organic matter linkages in waters draining arable fields

   University essay from SLU/Dept. of Soil and Environment

   Author : Adam Eriksson; [2021]
   Keywords : Natural organic matter NOM ; particular organic matter POM ; dissolved organic matter DOM ; allochthonous; autochthonous; Florescence index FIX ; Freshness index BIX ; Humification index HIX ; SUVA 254; E2:E3; Spectral Slope; Observation fields; microbial matter; humic matter; unfiltered samples UF ; filtered samples F45 ;

   Abstract : This study investigated leaching of natural organic matter (NOM) in twelve Swedish arable fields with regards to the quality of dissolved organic matter (DOM) and particulate organic matter (POM), using Absorbance (UV-Vis) and fluorescence spectrometry (EEM). DOM is defined as organic matter (OM) 0.45 μm. READ MORE

6. 35. Automated Control System for Dust Concentration Measurements Using European Standard Reference Method

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

   Author : Gustav Marstorp; [2021]
   Keywords : Dust concentration measurements; Particle concentration; Isokinetic deviation; PID-controller; EU standard 13284-1:2017; Stoftmätning; Partikelkoncentration; PID-regulator; Isokinetisk avvikelse; EU standard 13284-1:2017;

   Abstract : Most companies that have any type of combustion or other pollution process via emission to air needs to measure their emissions to ensure they are within legal boundaries. Among the different types of pollution measurements, one of the most common is dust concentration, also known as particle concentration. READ MORE
