    University essay from Karlstads universitet

    Author : Robin Lundström; [2019]
    Keywords : Machine learning; ML; Echo State Map; ESM; Echo State Network; ESN; Gaussian Process; GP; Computational Fluid Dynamics; CFD; Theory-Guided Data Science; TGDS; Physics-Guided Data Science; Data science; Cross-discipline; Hybrid model; MatLab; Maskininlärning; ML; Echo State Map; ESM; Echo State Network; ESN; Gaussiska Processer; GP; Beräkningsströmningsdynamik; CFD; MatLab;

    Abstract : In industrial environments, operators are exposed to polluted air which after constant exposure can cause irreversible lethal diseases such as lung cancer. The current air monitoring techniques are carried out sparely in either a single day annually or at few measurement positions for a few days. READ MORE

  4. 3. Static and Dynamic Characterization of power semiconductors

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

    Author : Alexandre Mejean; [2019]
    Keywords : Characterization; Semiconductors; Power Electronics; Power Switches; Test bench; Hard Switching; Soft Switching; Full bridge; Static characterization; Dynamic characterization; Power converter; Power loss; Probes; Measurement; High Current; Medium Voltage; Karakterisering; Halvledare; Kraftelektronik; Strömbrytare; Testbänk; Dynamisk karakterisering; Statisk karakterisering;

    Abstract : Characterizing  power  switches  is  an  indispensable  step  when  designing  a  converter.  This  thesisinvestigates ways to achieve static and dynamic characterization of semiconductors for high power applications such as power grid or train traction. The static characterization has been tested with a Keysight B1506A device analyzer. READ MORE

  5. 4. Characterization of Cascade gearbox for wave energy converter

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Jacob Ljungbäck; [2015]
    Keywords : Dynamic; Static; Model; Cascade; Gear; Backlash; Dynamisk; Statisk; Modell; Kaskad; Kugghjul; Flankspel;

    Abstract : This Master Thesis, written in collaboration with CorPower Ocean, serves as the finalization of the author’s master degree education at KTH (Royal Institute of Technology) Stockholm. The purpose has been to characterize the Cascade gearbox which is used to convert vertical motion induced by waves to rotational motion which powers generators in the company’s future wave energy power plant.

  6. 5. Electrophysiological characterization of striatalneurons through dynamic I-V curves

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : MATTHIJS DORST; [2013]
    Keywords : ;

    Abstract : Dynamic I-V curves constitute a naturalistic approach to electrophysiological neuronal characterization. Instead of analyzing a cells response to simple current injections and waiting for the cell membrane to stabilize, a dynamic I-V curve is generated by injecting a more naturalistic, dynamic input and analyzing the membrane response over a prolonged period of time.
