Various applications need an electric machine that can provide a wide range of torque over a broad range of rotation speed and temperature. Dynamic testing, where the machine acceleration is compared to the deceleration slope, allows to scan through a wide scope of operation points with insignificant temperature rise. Therefore, the goal of this paper is to analyse the consistency of the rapid exp
Results related to time-mean pressure distributions around a circular cylinder in cross-flow are presented and discussed briefly with special emphasis on the effect of relative pressure hole size and the position of separation. Experiments cover Reynolds numbers from $0.2 imes 10^3$ to $2.1 imes 10^5$.
Abstract The present work investigates i) the occurrence and removal of pharmaceuticals at Swedish WWTPs, and ii) potential causes for differences in the removal efficiency of pharmaceuticals at wastewater treatment plants. Particular attention is directed at the biological treatment and the pharmaceutical removal capacity per unit biomass of activated sludges and carrier biofilms of different or
Boken skildrar hur byn Dannäs i västra delen av Småland växer fram ur ett förmedeltida samhälle, hur byn utvecklas och så småningom försvinner. Den visar också hur politiska skeenden speglas på lokalnivå och griper in i människors vardag. Mycket av innehållet är resultatet av omfattande studier i arkiv, till exempel skattelängder och kyrkböcker, men också äldre kartor. Boken är relevant, både fak
Long-distance migration is a strategy some animals use to survive a seasonally changing environment. To reach favorable grounds, migratory animals have evolved sophisticated navigational mechanisms that rely on a map and compasses. In migratory insects, the existence of a map sense (sense of position) remains poorly understood, but recent work has provided new insights into the mechanisms some com
An efficient method for increasing the dilution rate of brine water discharged into the sea is an inclined negatively buoyant jet from a single port or a multi-diffuser system. Such jets typically arise when brine is discharged from desalination plants. Two small-scale experimental studies were conducted to investigate the behaviour of a dense jet discharged into lighter ambient water. The first e
