  1. 1. Generation of attosecond X-ray pulses in free-electron lasers using electron energy modulation and undulator tapering

    University essay from Uppsala universitet/FREIA

    Author : Karl-Fredrik Boholm Kylesten; [2023]
    Keywords : attosecond; free-electron laser; XFEL; self-amplified spontaneous emission; SASE; tapering; energy modulation;

    Abstract : Free-electron lasers (FELs) are among the world's most intense artificial artificial sources of coherent light and are tunable to various wavelengths, including the X-ray spectrum. X-ray FELs (XFELs) are extremely useful for diffraction experiments to study molecules, materials, and quantum systems. READ MORE

  3. 2. Mapping DNNs onto the NoC Platform

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

    Author : Hanbo Xu; [2022]
    Keywords : ;

    Abstract : This thesis uses an existing NoC simulation platform to construct a Network on Chip-based many-core system. The network is an 8_8 mesh topology. This thesis chooses LeNet5, ResNet, VGGNet, and AlexNet as the computing load, and tries to obtain a deep neural network mapping algorithm based on a NoC design method that can be widely used.

  4. 3. Backscatter Communications for 6G

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Lakshmi Rajeev Cheekati; Jin Yan; [2022]
    Keywords : Technology and Engineering;

    Abstract : The success of future Internet of Things (IoT) depends on, among the other things, developing energy-effcient communication techniques that can enable information exchange among billions of IoT devices with ultra-low/zero power consumption requirements. Ambient backscatter communications is an emerging technology, which utilizes the ambient Radio Frequency (RF) signal as the carrier to reduce the form-factor, and the battery requirements of low-cost small sensor type communication devices.

  5. 4. Design and Construction of a Multi-Port Beamsplitter Based on Few-Mode-Fibers

    University essay from Linköpings universitet/Informationskodning

    Author : Daniel Spegel-Lexne; [2022]
    Keywords : beamsplitter; spatial modes; Space division multiplexing; superpositions; LP-modes; few-mode fibers; multi-mode interference; self-imaging; heterogeneous fiber structures; quantum communication; quantum optics;

    Abstract : A MBS (Multi-port beamsplitter) for higher dimensional quantum communication has been designed and constructed and the theory and method for this is presented in this thesis. It uses optical fibers in a heterogeneous structure with a single-mode fiber spliced to a multi-mode fiber and then spliced to a few-mode fiber. READ MORE

  6. 5. Virtualizing Montessori : Experiences of teachers working in  a fully remote Montessori preschool

    University essay from Linköpings universitet/Tema Barn

    Author : Gabrielle Kotkov; [2022]
    Keywords : Montessori; virtual school; preschool; online learning; Covid-19;

    Abstract : Virtual preschool seems to contradict the Montessori Method, a hands-on, sensorial-based early childhood curriculum. However, many virtual Montessori schools, borne out of the temporary need for isolation due to the Covid-19 pandemic, seek to continue this new implementation of Montessori education permanently.
