in conventional direct torque control (dtc), the stator flux is usually kept constant by controlling the x-axis component of the stator voltage in the stator flux reference frame. the torque is then controlled by the y-axis component of stator voltage. in this scenario, the stator current does not exceed its permissible value. however, in the so-called optimal efficiency mode, the induction mot...

BACKGROUND The study investigated the perspective of people with mobility limitations (PWML) in Zambia, firstly of their accessibility to public buildings and spaces, and secondly of how their capacity to participate in a preferred lifestyle has been affected. OBJECTIVES Firstly to provide insight into the participation experiences of PWML in the social, cultural, economic, political and civi...

BACKGROUND Mobility-related fatigue and low socioeconomic position predicts mobility limitations and disability in old age, but the interplay between these two factors is unknown. To evaluate whether mobility-related fatigue is a stronger risk factor for mobility limitations in certain socioeconomic groups, the aim of this study was to examine the combined effect of mobility-related fatigue and...

Abstract The presented experimental study realized in the COMPASS tokamak demonstrates, for first time, that current density flows from plasma into vacuum vessel during disruptions is limited by ion particle flux. Such a limitation shows that, at least COMPASS, sheath forms between and wall dominates halo flow. This observation achieved measuring simultaneously saturation with negatively biased...
