Systemic lupus erythematosus (SLE) can affect any part of the central nervous system (CNS) from the cerebrum to the cauda eqina, giving rise to diverse neurological mainfestations. Despite clinically apparent symptoms and signs, imaging will commonly

Previous work has shown that the k 2 term in the effective cooling velocity equation for inclined hot-wires can become negative under certain probe configurations and wire length-to-diameter ratios. It was hypothesised that this was due to a downwash

The work describes application of the [kappa]-[epsilon] turbulence model to a fully pulsed air jet. The standard model failed to predict the change in slope of the velocity decay where the jet changes from pulsed to steady jet behavior. A change in o

The controlled processor has been proposed as a means of avoiding velocity bias in laser Doppler anemometry. A theoretical model is presented to show that results free of bias can be obtained if both the ratio of integral time scale to measurement ti

Sample and hold processors may be used to avoid velocity bias errors in laser Doppler anemometer (LDA) measurements if the ratio of flow to measurement time scale is sufficiently high, typically greater than 5. It has been widely assumed that the flo

A technique is described for unsteady flow measurements which permits automatic time-constant adjustment of a cold-wire resistance thermometer by placing it parallel to one of the inclined wires of a multi-wire hot-wire anemometer array. It is shown

The response of inclined hot wires operated in the constant wire temperature mode to fluid temperature variations was explored experimentally over a range of incident angles from 5 degrees to 85 degrees . Results showed that the square of the output

Constant-current anemometers operating as resistance thermometers are ideally suited for measurement of stream temperature fluctuations. In order to extend their limited frequency response due to the thermal inertia of the wire, open-loop compensatio
