1. 1. Lithium-ion Battery Modeling and Simulation for Aging Analysis using PyBaMM

   Master-uppsats, Linköpings universitet/Institutionen för systemteknik

   Författare :Amina Coric; [2022]
   Nyckelord :Battery charging; Lithium-ion; Doyle-Fuller Newman; P2D; Single Particle Model; Pulse Charging; Constant Current Constant Voltage; Solid Electrolyte Interphase; SEI; Lithium Plating; Cycle Life; Cyclic Aging; PyBaMM; Batteri laddning; Litiumjonbatteri; Doyle-Fuller Newman; P2D; Singelpartikelmodell; Pulsad Laddning; Konstant Ström Konstant Spänning; Fast Elektrolytinterfas; SEI; Litiumplätering; LP; Cykellivslängd; Cykliskt Åldrande; PyBaMM;

   Sammanfattning : The rate of degradation of a lithium-ion battery depends on its use i.e. how it is charged and discharged. Physics-based models are used to represent the processes inside a cell as well as the degradation mechanisms. LÄS MER

3. 2. Development and Use of System Modeler 6DOF Flight Mechanics Model in Aircraft Conceptual Design

   Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

   Författare :Niko Erä-Esko; [2022]
   Nyckelord :Aircraft Conceptual Design; Flight Mechanics; Modelling and Simulation;

   Sammanfattning : This thesis presents a tool for conceptual design of a traditional configuration aircraft by using a parametric six degrees of freedom (6DOF) flight mechanics model implemented in the Modelica Language using Wolfram System Modeler. Being first only able to model and simulate the uncontrolled flight of an aircraft with fixed mass and centre of gravity (CG), and requiring detailed aerodynamic parameters as an input, the 6DOF model is improved by developing new features to reduce the number of required inputs while also increasing the data output of the simulations.

4. 3. Driver model for a software in the loop simulation tool

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Yue Zheng; [2019]
   Nyckelord :HDV Heavy duty vehicle ; simulation tool; Driver model; longitudinal velocity controller; HDV tungt fordon ; simuleringsverktyg; förarmodell; longitudinell hastighetsregulator;

   Sammanfattning : For this project, a Software-In-the-Loop (SIL) simulation tool is used at Scania (“VTAB” – Virtual Truck and Bus), which simulates the submodels of the mechanical vehicle components together with the real control units. The simulation tool contains the following submodels: Engine model, Drivetrain model, Drive cycle model, Restbus model, and Driver model. LÄS MER

5. 4. Inflated Multinomial Matching for Anchor-Free Object Detection

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Cesar Hiersemann; [2018]
   Nyckelord :Computer Vision; Machine Learning; Deep Learning; Convolutional Neural Networks; Object Recognition; Object Detection; Anchors; Anchor Boxes; Mathematics and Statistics;

   Sammanfattning : This thesis presents a novel matching strategy, Inflated Multinomial Matching, which enables training of anchor-free object detection models based on convolutional neural networks. An important aspect of detection models is the integral usage of anchor boxes, where an anchor box is a bounding box with a preset and constant location, size and shape in the image. LÄS MER

7. 5. Automatic Predicate Encapsulation of Potentially Profitably Presolvable Submodels in MiniZinc

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Alexander Ek; [2018]
   Nyckelord :;

   Sammanfattning : An underused feature of the MiniZinc language for modelling combinatorial problems is that its models can be parsed, analysed, and modified; however, this could enable modellers to improve their modelsin novel ways. The auto-tabling tool of Jip J. LÄS MER
