  1. 1. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Isa Clementsson; [2023]
    Keywords : Physics and Astronomy;

    Abstract : Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficiencies as high as a few percent.

  3. 2. Spatio-temporal modelling and mapping of network coverage for connected vehicles

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Deepthi Pathare; [2022]
    Keywords : ;

    Abstract : Digital connectivity plays a major role in enabling sustainable transport solutions. A key ingredient that ensures this connectivity is the cellular network coverage, whose information is typically available from the service providers. READ MORE

  4. 3. Prioritization of Informative Regions in PET Scans for Classification of Alzheimer's Disease

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Fredrik Mårtensson; Erik Westberg; [2021]
    Keywords : ;

    Abstract : Alzheimer’s Disease (AD) is a widespread neurodegenerative disease. The disease causes brain atrophy, resulting in memory loss, decreased cognitive ability, and eventually death. There is currently no cure for the disease, but treatment may delay the onset. Therefore, it is crucial to detect the disease at an early stage. READ MORE

  5. 4. Real-time Outlier Detection using Unbounded Data Streaming and Machine Learning

    University essay from Luleå tekniska universitet/Datavetenskap

    Author : Emelie Åkerström; [2020]
    Keywords : Outlier Detection; Unbounded Data Streaming; Machine Learning; Clustering; MiniBatchKMeans; LSTM AutoEncoder; Streaming; Network Monitoring;

    Abstract : Accelerated advancements in technology, the Internet of Things, and cloud computing have spurred an emergence of unstructured data that is contributing to rapid growth in data volumes. No human can manage to keep up with monitoring and analyzing these unbounded data streams and thus predictive and analytic tools are needed. READ MORE

  6. 5. Generation and Characterization of Intense Attosecond Pulses

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Marius Plach; [2020]
    Keywords : Attosecond physics; high-order harmonic generation; high harmonic generation; HHG; attosecond pulses; molecular dynamics; attosecond pulse generation; harmonic emission time delay; temporal reconstruction of attosecond pulses; strong field processes; Three-step model; RABBIT; Reconstruction of Attosecond Beating By Interference of Two-photon Transition; Terawatt Laser System; Intense XUV Beamline; XUV; LLC; Physics and Astronomy;

    Abstract : Research on ultrafast dynamics in atoms and molecules requires short pulses. In order to resolve processes taking place on a femtosecond timescale sufficiently, these pulses require a duration on the attosecond time scale. READ MORE
