  1. 11. Factors related to outcome in patients with traumatic brain injury : with special reference to analysis with machine learning methods

    Författare :David Nelson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Traumatic brain injury; Glasgow coma scale; Glasgow outcome scale; microdialysis; computed tomography; hematologic tests; machine learning;

    Sammanfattning : Traumatic brain injury (TBI) is a leading cause of death in trauma. Neurointensive care (NICU) units have emerged to optimize treatments of the injured brain. The main objective is to identify and avoid conditions that lead to further insult and potential cell death. LÄS MER

  3. 12. Diagnostics of stator insulatin by dielectric response and variable frequency partial discharge measurements : a study of varied low frequencies in stator insulation, with particular attention to end-winding stress-grading

    Författare :Nathaniel Taylor; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Sammanfattning : Stator insulation is a critical to the reliability of electrical generators and motors. It is common industrial practice to use electrical measurement of partial discharges (PD) and some form of current-voltage measurement as part of the condition assessment of stator insulation at maintenance times.

  4. 13. Noise reduction of hydraulic systems : design considerations and methods

    Författare :Andreas Johansson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : AS A CONSEQUENCE OF increased requirements concerning pleasant working conditions, the system designer of today is facing challenges besides the traditional performance related ones. Subjects such as cleanliness, low sound and vibration levels etc. play important roles in modern system development. LÄS MER

  5. 14. Dielectric response and partial discharge measurements on stator insulation at varied low frequency

    Författare :Nathaniel Taylor; Hans Edin; Shesha Jayaram; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric power engineering; Elkraftteknik;

    Sammanfattning : This is a study of potential improvements of diagnostic methods used on high-voltage generators and motors.  It considers offline electrical measurements on the main insulation of stator windings, where a sinusoidal voltage is applied between the winding and the stator-core, and the total current through the insulation (dielectric spectroscopy, DS) and the rapid current-pulses arising from discharges (partial discharge, PD) are measured.

  7. 15. We are (not) anonymous : Essays on anonymity, discrimination and online hate

    Författare :Joakim Jansson; Björn Tyrefors; Björn Öckert; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Anonymity; Discrimination; Hate; Applied Econometrics; Gender Economics; Labor Economics; Political Economics; Behavioral Economics; Economics; nationalekonomi;

    Sammanfattning : Haters gonna hate? - Anonymity, misogyny and hate against foreigners in online discussions on political topics. A crucial aspect of freedom of expression is anonymity, but anonymity is a contentious matter. It enables individuals to discuss without fear of repercussions, but anonymity can also lead to hateful writings threatening other's freedom. LÄS MER
