  1. 16. 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

    Master-uppsats, Linköpings universitet/Fordonssystem

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

    Sammanfattning : 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. LÄS MER

  2. 17. Classification of EEG Data Using Convolutional Neural Networks and the Scaled Reassigned Spectrogram

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Karin Pagels; [2021]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Electroencephalography (EEG) is a medical technique for measuring brain activity through several channels connected to the scalp. Interpreting EEG data is a difficult problem because of the large amount of noise contained in the data. LÄS MER

  3. 18. Comparing Analog and Digital Non-Linear Sonic Signatures : an Investigation on Creative Application and Subjective Perception using the Universal Audio 1176 FET Compressor

    Kandidat-uppsats, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Behzad Mehrnoosh; [2021]
    Nyckelord :compression; compressor; non-linear; distortion; sonic signature; analog; hardware; digital; software; emulation; modeling; 1176;

    Sammanfattning : Historically, compression was primarily used as a preventative measure to reduce the risk of clipping or overloading equipment in the recording signal chain. Research on the topic has revealed that modern production applications more commonly include utilizing compression as a creative effect, to impart distortion, manipulate timbre, and modify transients, rather than to control the dynamic range of audio signals.

  4. 19. Dynamic Modeling of Target's Cooling Systems

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Maximilian Cahlin; [2021]
    Nyckelord :Dynamic modeling; Modelica; Dymola; Fluid mechanics; Thermodynamics; Technology and Engineering;

    Sammanfattning : The thermal energy generated from the spallation process in the ESS facility must be cooled by cooling systems in order to ensure safe operation of the facility. It is of interest to understand what operating conditions of the cooling systems will ensure this safety for both stationary conditions and transient events. LÄS MER

  5. 20. High-Redshift Gamma-ray Bursts as seen by SVOM/ECLAIRs

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Miguel Llamas Lanza; [2021]
    Nyckelord :Gamma-ray Bursts; GRBs; compact objects; high energy; ECLAIRs; SVOM; high redshift; T90; detection biases;

    Sammanfattning : Gamma Ray Burst (GRB) are very bright cosmological explosions signalling the catastrophic formation of a black hole. Therefore, they act like real light beacons that could be detected through-out the Universe and be used as probes to study the contents and phases of the early Universe. However, only a handful sample is known so far. LÄS MER
