  1. 16. Improving a Background Model for Tracking and Classification of Objects in LiDAR 3D Point Clouds

    University essay from Lunds universitet/Matematik LTH

    Author : Seamus Doyle; Gustav Nilsson; [2022]
    Keywords : LiDAR; Semantic Segmentation; Neural Networks; RandLA-NET; 3D Point Cloud; Gaussian Process Regression; Robust Locally Weighted Regression; CARLA; Ground Model; Technology and Engineering;

    Abstract : This thesis studied methods of improving a background model for a data processing pipeline of LiDAR point clouds. For this, two main approaches were evaluated. The first was to implement and compare three different models for detecting ground in a point cloud. These were based on more classical modeling approaches. READ MORE

  3. 17. Optimal Control and Thermal Managementof Heavy-Duty FCHEV Powertrains : Minimizing hydrogen consumption of an FCHEV using numerical optimal control and an integrated energy and thermal management system

    University essay from Linköpings universitet/Fordonssystem

    Author : Daniel Similä; Jonatan Siönäs; [2022]
    Keywords : Control Engineering; Powertrain Engineering; FCHEV; Optimal Control; Thermal Management;

    Abstract : The CO2 emissions from road vehicles must be reduced in order to avoid a 1.5 ◦C global warming. To reduce tailpipe emissions, a strong trend is to electrify powertrains to shift away from the use of fossil fuel. Among alternatives, the fuel cellhybrid electric vehicle (FCHEV) is seen as a promising configuration. READ MORE

  4. 18. Hydrogen Fuel Cell Lifetime Simulation in Marine Applications

    University essay from KTH/Kraft- och värmeteknologi

    Author : Yifeng Zhong; [2022]
    Keywords : maritime transportation; FEMFC; lifetime simulation; degradation mechanism; empirical relationship; semi-empirical approach; sjötransport; PEM-bränsleceller; livslängdssimulering; nedbrytningsmekanism; empiriskt samband; semi-empiriskt tillvägagångssätt;

    Abstract : Maritime transportation emits about 3% of global greenhouse gas, International Maritime Organization (IMO) aims to reduce shipping’s emissions by 50% with respect to 2008 levels. Proton exchange membrane fuel cells (PEMFCs) are considered among the most promising clean technologies for decarbonizing the maritime sector. READ MORE

  5. 19. Risk of getting caught and its impact on residential burglaries : Panel study of residential burglaries and clearance rates in Swedish counties in the period 2001-2013

    University essay from Umeå universitet/Nationalekonomi

    Author : Fredrik Öhrner; [2022]
    Keywords : ;

    Abstract : Research on deterrence from crime is often about the strength of possible punishment, but less often about the risk of getting caught as a deterrent. According to rational choice theory, the risk of getting caught should have a deterrent effect. READ MORE

  6. 20. LSTM Feature Engineering Through Time Series Similarity Embedding

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Sebastian Bångerius; [2022]
    Keywords : Embedding; time series; LSTM; feature engineering; DTW; correlation; prediction;

    Abstract : Time series prediction has many applications. In cases with simultaneous series (like measurements of weather from multiple stations, or multiple stocks on the stock market)it is not unlikely that these series from different measurement origins behave similarly, or respond to the same contextual signals.
