  1. 1. Power Reconstruction Uncertainties in European Pressurized Reactor Impact of Partial. Unavailability of Sensors

    Master-uppsats, KTH/Fysik

    Författare :Matthieu Causse; [2022]
    Nyckelord :;

    Sammanfattning : This study is part of a theme related to the physical tests performed on the core of nuclear reactors and particularly the EPR, a new French reactor under construction on the Flamanville site. The peaking factors of this reactor are continuously monitored by an instrumentation located both inside (collectrons) and outside (external fission chambers) the core. LÄS MER

  3. 2. PCBA verification and fault detection using a low-frequency GMR-based near-field probe with magnetic closed-loop feedback compensation : A non-contact alternative to physical probing

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Joacim Sundh; [2022]
    Nyckelord :GMR; sensor; magnetic field; near-field; probe; linearity; PCB; coil; PCBA; analogue integrated circuits; analog; operational amplifiers; electrical fault detection; feedback circuits; in-circuit tests; GMR; sensor; magnetfält; närfält; sond; linjäritet; mönsterkort; spole; kretskort; analoga integrerade kretsar; operationsförstärkare; elektrisk feldetektering; återkopplingskretsar; kretskortstest;

    Sammanfattning : As electronics are getting both smaller and more advanced, the need to verify and validate remains and the means are getting more complex the more functions and components are added. Traditionally, in-circuit tests (ICTs) are performed by probing dedicated test points on the Printed Circuit Board Assembly (PCBA) in a test sequence that is unique to each product. LÄS MER

  4. 3. Constructing an optical tweezers instrumentation and evaluation of trapping stiffness using the power spectrum method

    Kandidat-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Haoxiang Yang; [2022]
    Nyckelord :;

    Sammanfattning : Optical tweezers can trap micron-sized objects such as cells, bacteria, and microspheres, and has become an important instrument for measuring forces associated with various physical and biological phenomena. In this thesis work, I constructed an optical tweezers instrument to trap 2µm diameter beads using a HeNe-laser operating with a wavelength of 632. LÄS MER

  5. 4. Utveckling av en generell metod för läckageövervakning vid fyllningsdammar

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Alia Gasim; [2020]
    Nyckelord :Embankment dam; seepage; measuring instrumentation; normal seepage; water balance equation; Fyllningsdamm; läckageövervakning; mätinstrument; normalt läckage; vattenbalansekvation;

    Sammanfattning : Fyllningsdammar har alltid ett naturligt läckage då jordmaterialet som används har en viss permeabilitet. Detta acceptabla naturliga läckage är viktigt att övervaka för att kontrollera att läckageflödet håller sig inom förväntade värden. LÄS MER

  7. 5. Mapping The Valleys of The Uncanny : An investigation into a process and method, colliding with questions relating to what can be known to be real, within the field of algorithmic composition. Or if you prefer: The roles of instrumentation and timbre, as they unwittingly conspire to designate access, power, status, work and ultimately class.

    Master-uppsats, Kungl. Musikhögskolan/Institutionen för komposition, dirigering och musikteori

    Författare :Daniel M Karlsson; [2019]
    Nyckelord :Algorithmic Composition;

    Sammanfattning : We are free, from the shackles of the finite, and of the physical world. Sound now enjoys morphological freedom through a myriad of transformations. It is malleable to the utmost degree. We have at our disposal an astounding plethora of tools, with which we can manipulate and organise sound. LÄS MER
