2. 1. Temporal representation of Motor Imagery : towards improved Brain-Computer Interface-based strokerehabilitation

   Author : Jonatan Tidare; Elaine Åstrand; Pawel Herman; Mälardalens högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain-computer interface; eletroencephalogram; stroke rehabilitation;

   Abstract : Practicing Motor Imagery (MI) with a Brain-Computer Interface (BCI) has shown promise in promoting motor recovery in stroke patients. A BCI records a person’s brain activity and provides feedback to the person in real time, which allows the person to practice his or her brain activity. READ MORE

4. 2. Imaging imagining actions

   Author : CJ Olsson; Lars Nyberg; A.Mark Williams; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mental training; motor training; novices; imaging; athletes; fMRI; internal imagery; motor representation; brain systems; practice; learning; transfer; active; Physiology; Fysiologi;

   Abstract : Mental training has been studied extensively for the past century but we are still not completely sure how it affects brain and behavior. The aim of this doctoral thesis was to examine one aspect of mental training i.e. motor imagery. READ MORE

5. 3. The role of cortico-basal ganglia systems in the construction of movement: Action selection and sequencing

   Author : Joel Sjöbom; Integrativ neurofysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurophysiology; Electrophysiology; Voluntary movements; In-vivo; Motor Cortex; Corticostriatal; Basal Ganglia;

   Abstract : The cortico-basal ganglia system is instrumental in the construction of movement, through its involvement in aspects such as action selection, initiation/termination and sequencing, though the precise role of the different structures and how they collaborate on a network level to allow us to fluidly change from one behavior to another has long proven to be elusive.We have here recorded neuronal activity throughout the cortico-basal ganglia circuit in rats, in a series of projects in order to understand more about how some of these functions are controlled.

6. 4. On the Utility of Representation Learning Algorithms for Myoelectric Interfacing

   Author : Alexander Olsson; Avdelningen för Biomedicinsk teknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMG; Machine Learning; Deep Learning; Feature Learning; Biosignal Processing; Gesture Recognition; Muscle-Computer Interfaces; Myoelectric Control; Upper-Limb Prosthetics;

   Abstract : Electrical activity produced by muscles during voluntary movement is a reflection of the firing patterns of relevant motor neurons and, by extension, the latent motor intent driving the movement. Once transduced via electromyography (EMG) and converted into digital form, this activity can be processed to provide an estimate of the original motor intent and is as such a feasible basis for non-invasive efferent neural interfacing.

7. 5. Distributed control of electric drives via Ehernet

   Author : Lilantha Samaranayake; KTH; []
   Keywords : Brushless DC Motor; Control Delay; Distributed Motion Control Systems; Proportional Integral Controller;

   Abstract : This report presents the work carried out aiming towardsdistributed control of electric drives through a networkcommunication medium with temporal constraints, i.e, Ethernet.A general analysis on time delayed systems is carried out,using state space representation of systems in the discretetime domain.
