  1. 1. Single event upsets: measurements and modelling of proton- and neutron-induced errors in a 28 nm SRAM-based FPGA

    Författare :Markus Preston; Per-Erik Tegnér; Samuel Silverstein; Pawel Marciniewski; Andreas Heinz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Single event upset; FPGA; radiation damage; Monte Carlo simulation; PANDA; fysik; Physics;

    Sammanfattning : Single event upsets are radiation-induced errors affecting electronic devices, which can cause corruption of processed data. The electromagnetic calorimeter of the PANDA experiment — a hadron-physics experiment currently under development — will employ Xilinx Kintex-7 field-programmable gate arrays (FPGAs) in its readout electronics.

  3. 2. Developments for the FPGA-Based Digitiser in the PANDA Electromagnetic Calorimeters

    Författare :Markus Preston; Per-Erik Tegnér; Samuel Silverstein; Pawel Marciniewski; Allan Hallgren; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PANDA; calorimeter; FPGA; single event upset; Geant4; Monte Carlo; pile-up; feature extraction; fysik; Physics;

    Sammanfattning : The strong interaction between quarks and gluons is one of the fundamental interactions described by the standard model of particle physics. Systems of quarks bound together by the strong interaction are known as hadrons, of which the proton and the neutron are the most common examples. LÄS MER

  4. 3. Empirical Essays on Railway Infrastructure Costs in Sweden

    Författare :Mats Andersson; Lars-Göran Mattsson; John Preston; KTH; []
    Nyckelord :Railways; Infrastructure; Marginal Costs; Maintenance; Renewal; Econometrics; Panel Data; Survival Analysis; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : The subject of this thesis concerns pricing the use of transport infrastructure. We are empirically investigating the relationship between railway traffic volumes and infrastructure management costs. More specifically, we are interested in estimating the change in infrastructure management costs from marginal variations in traffic volumes, i.e. LÄS MER

  5. 4. Interfacial Adhesion Failure : Impact on print-coating surface defects

    Författare :Hajer Kamal Alm; Lars Wågberg; Göran Ström; Janet Preston; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ink-paper coating adhesion; offset printing; calcium carbonate pigments; polyacrylate; dispersant; print mottle; surface chemistry; hygroscopy of surfaces; coating structure; print quality; water interference mottle; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The aim of this work was to develop a solid knowledge on formulation effects controlling offset ink-paper coating adhesion and to identify key factors of the coating and printing process affecting it. Focus lay on comprehending the impact of pigment dispersant on ink-paper coating adhesion and ultimately on the print quality of offset prints. LÄS MER

  7. 5. Listening to the voice of children : systemic dialogue coaching. Inviting participation and partnership in social work

    Författare :Ann-Margreth E. Olsson; Michael Preston-Shoot; Peter Lang; Jenny Pearce; Jane Dutton; Angus Duncan; Högskolan Kristianstad; []
    Nyckelord :systemic; dialogue; coaching; investigation; social work; welfare; protection; children; client; social worker; coach; participation; partnership; involvement; listening; presence; relationship; joint action; action research; PAR; dialogical; systemisk; samtal; dialog; coaching; utredning; socialt arbete; välfärd; skydd; barn; klient; socialarbetare; social sekreterare; coach; deltagande; delaktighet; partnerskap; involvering; lyssnande; nuet; relation; samhandling; aktionsforskning; deltagande aktionsforskning; dialogisk;

    Sammanfattning : This is a study in and about systemic coaching in social work – systemic, and, as it unfolded, dialogical coaching, later named Dialogue Coaching (DC). Focus lies on what the conducted coaching brought forth, generated and created in the context of social work and for the members of the participating social welfare organisations. LÄS MER
