  1. 11. Vestibular control of body orientation in lamprey

    Författare :Elena Pavlova; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Postural control; orientation; vision; vestibular system; visuo-vestibular interaction; vestibular compensation; locomotion; supraspinal control; lamprey;

    Sammanfattning : Maintenance of body orientation (postural control) is a vital motor function of the brain. The general goal of this project was to understand the organization and operation of neuronal networks responsible for postural control. The lamprey (a lower vertebrate) was used as a model animal.

  3. 12. On Active Suspension in Rail Vehicles

    Författare :Alireza Qazizadeh; Sebastian Stichel; Rickard Persson; T. X. Mei; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active suspension; ride comfort; wear; skyhook control; H_infinity control; two-axle rail vehicle; safety; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : The topic of this PhD thesis is active suspension in rail vehicles whichis usually realized through sensors, controllers and actuation components.A well established example of an active suspension is the tiltingcontrol system used to tilt the carbody in curves to reduce centrifugalacceleration felt by passengers.

  4. 13. Fluid dynamic principles for analysis of intracranial pressure control : application towards space medicine and hydrocephalus

    Författare :Petter Holmlund; Anders Eklund; Sara Qvarlander; Jan Malm; Marek Czosnyka; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intracranial pressure; posture; cerebrospinal fluid; microgravity; venous collapse; internal jugular vein; fluid dynamics; venous pressure; spaceflight-associated neuro-ocular syndrome; hydrocephalus; mathematical modeling; ultrasound; magnetic resonance imaging;

    Sammanfattning : Intracranial pressure (ICP) is an important component of the fluid dynamic environment of the brain and plays a central role with regards to the maintenance of normal cerebral blood flow and neuronal function. However, many regulatory mechanisms controlling the ICP are still poorly understood. LÄS MER

  5. 14. Multisensory control of gaze stabilization : from brainstem to bedside

    Författare :Tobias Wibble; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Without the continuous updates provided by the vestibular and visual systems, our world would appear blurry and unstable. In order to allow the retina to reliably record incoming light in a meaningful way, the vestibulo-ocular reflex (VOR) and optokinetic reflex (OKR) aim to stabilize our gaze on visual features.

  7. 15. Assisted Tele-Remote Control of Wheel Loaders in Underground Mining

    Författare :Siddharth Dadhich; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : Tele-remote operation of mobile earth-moving machines in underground mines supported byoperator assistance functions is attractive for safety and productivity reasons. This way, operatorscan avoid hazardous underground environments with poor air quality and the productivitycan, in principle, be improved by saving the time required to commute drivers to and fromthe operational areas.
