Somali Current: Evolution of Surface Flow

Science, 1980
The transition of the Somali Current from northeast monsoon conditions to southwest monsoon conditions was observed from April through August 1979. The northeastward flow associated with the Somali Current of the southwest monsoon progressed from the equator in April to 4° N in August.

The current status of tribological surface science

Tribology Letters, 2001
Use of the ultrahigh vacuum methods of surface science allows the preparation and study of highly characterized solid–solid interfaces for tribological investigations. One of the limiting factors in the progress of our understanding of tribology has been the inability to generate solid–solid interfaces with well-defined, reproducible, atomic scale ...

Current balance at the surface of a cold cathode

Physical Review Letters, 1987
Recent experimental and theoretical developments, including an electric field diagnostic based on optogalvanic detection of Rydberg atoms, an analytic treatment of ion transport in the cathode fall, and a null collision Monte Carlo technique, are combined to determine the current balance at the surface of a cold cathode in a He glow discharge.

A surface current meter

Continental Shelf Research, 1987
Abstract A newly developed current meter is described which has been designed to record near-surface currents of relatively high speed in an Eulerian frame. With a Weller/Davis propeller and a gimballed compass, the Rapid Boundary Current Meter (RBCM) vector averages under microprocessor control and logs into solid state memory.

Surface current mapping in the lower Chesapeake

OCEANS 2008, 2007
Three CODAR 25 MHz RADAR antennas have been installed in the lower Chesapeake Bay to observe surface currents. Over the past year, data have been produced that will be valuable for researchers, commercial and recreational interests. In this paper we give a description of the antenna sites, examples of data products, a comparison of CODAR data with ...

Measurement of Surface Currents

Journal of Navigation, 1986
Knowledge of surface currents is of fundamental importance in many diverse marine activities; for example in navigation, offshore engineering and operations, and in the prediction and monitoring of the movement of pollutants. In those areas of scientific research directed towards improved understanding of climate, and towards the modelling and ...

Current trends in advanced surface ablation

Current Opinion in Ophthalmology, 2008
Since their introduction in the mid-1990s, surface ablation techniques have continued to evolve, enabling surgeons to give patients better quality of vision with less postoperative pain. The purpose of this chapter is to discuss that evolution, the common techniques used today, and how to address potential complications.Advanced surface ablation ...

On the origin of the ‘surface current’ in turbulent free-surface flows

Journal of Fluid Mechanics, 1997
In this study, the interaction with a free surface of an initially axisymmetric jet issuing beneath and parallel to the surface was examined. The purpose was to determine the origin of the ‘surface current’ – the large outward velocity which exists in a thin layer adjacent to the surface.

Ocean surface currents mapped by radar

Proceedings of the 1978 IEEE First Working Conference on Current Measurement, 2005
A high-frequency radar remote-sensing system for measuring and mapping near-surface ocean currents in coastal waters has been analyzed and described. A transportable prototype version of the system was designed, constructed, and tested. With two units operating tens of kilometers apart, the currents were mapped in near real time at a grid of points 3 ...

Tunneling Current Between Two Nonplanar Surfaces

Physical Review B, 1988
The problem of determining the tunneling current between two electrodes that are nonplanar is essential to the theory of Scanning Tunneling Microscopy (S.T.M.) [1’10]. J. Tersoff and D. R. Hamann have shown that for a spherical tip as one electrode, and including only an evanescent s wave function, the current is proportional to the local density of ...
