Abstract Two phase flow is of great interest in chemical and petroleum industries, multiphase pipe models with closure relationships require experimental data for their development validation. However, only little information available slightly upward inclined pipes. Experimental investigations single elongated bubble marginally upwardly pipes less than 10° have therefore been performed. Observ...

We studied sinusoidal (SIN) and step-ramp (SR) pursuit in two rhesus monkeys, before and after surgical lesions of the cerebellar nodulus and uvula (Nod/Uv). Eye movements were recorded using the magnetic field scleral search coil method. Pursuit targets were generated by an LCD projector and back-projected onto a tangent screen in an otherwise dark room. After the Nod/Uv lesions, both monkeys ...

We describe the statistical properties of narrowband drifting auroral kilometric radiation (’striated’ AKR) based on observations from the Cluster wideband receiver during 2002-2005. We show that the observed characteristics, including frequency drift rate and direction, narrow bandwidth, observed intensity, and beaming angular sizes are all consistent with triggering by upward traveling ion so...

The authors characterize impacts on heat in the ocean climate system from transient ocean mesoscale eddies. Their tool is a suite of centennial-scale 1990 radiatively forced numerical climate simulations from three GFDL coupledmodels comprising the ClimateModel, version 2.0–Ocean (CM2-O), model suite. CM2-O models differ in their ocean resolution: CM2.6 uses a 0.18 ocean grid, CM2.5 uses an int...

Semi-active base isolation system has been proposed mainly to mitigate the base drift of isolated structures while in most cases, its application causes the maximum acceleration of superstructure to be increased. In this paper, designing optimal semi-active base isolation system composed of linear base isolation system with low damping and magneto-rheological (MR) damper has been studied for co...

In this editorial, I pass on to a new team. South African Computer Journal has moved long way since took over as editor-in-chief 10 years ago and am pleased that we have new, enthusiastic team who will take it heights.
