The relationship between the gyre-scale circulation of the North Atlantic, represented by air pressure near to the centre of the sub-tropical gyre, and sea level measured at the eastern boundary of the ocean has been investigated using records commencing in the middle of the 18th century. These time series are twice as long as those employed in an earlier study of this relationship. Near-contin...

The shoreline is one of the most important features on earth’s surface. It is valuable to a diverse user community. But the dynamic nature of the shorelinemakes it difŽ cult to be represented in a naturally dynamic style and to be utilized in applications.The ofŽ cially usedshoreline,for examplein nauticalcharts,is the so-calledtide-coordinatedshoreline. It is also the shoreline that makes the ...

This paper reports the results of a study concerned with air–water and air–oil two-phase flow in channels packed open-cell metal foams. The research was conducted horizontal channel an internal diameter 0.02 m length 2.61 m. analysis applied three foams pore density 20, 30, 40 PPI porosity typical for industrial applications, changing range 92–94%. experimental data were used to develop new met...

The paper discusses the details of application method fluid substitution which is used for predicting elastic properties reservoir rocks and their dependence on pore porosity. This makes it possible to predict changes in response a rock saturation with different fluids. main task this was study productive zones visean deposits Yablunivske field using example single well. integration petrophysic...

A significant part of all types measurements performed in modern industry and science are gas, liquid or other media. This is important because there many processes where you need to clearly control the parameters environment - pressure, density, etc. The object research MEMS gas density sensors. subject eliminate shortcomings existing similar systems, increase accuracy measurement range measur...

Relativistically broadened and redshifted 6.4 -- 6.9 keV iron K lines are observed from many accretion powered objects, including X-ray binaries active galactic nuclei (AGN). Existence of gas close to the central engine implies large radiation intensities correspondingly densities if is remain partially ionized. Simple estimates indicate that high needed allow survival against ionization. These...

Analytical gas-permeation models for predicting the separation process across  membranes (exit compositions and area requirement) constitutes an important and necessary step in understanding the overall performance of  membrane modules. But, the exact (numerical) solution methods suffer from the complexity of the solution. Therefore, solutions of nonlinear ordinary differential equations th...

Ever since the first fishermen ventured into the sea, tides have been the subject of intense human observation. As a result computational models and ‘tide predicting machines’, mechanical computers for predicting tides have been developed over 100 years ago. In this work we propose a statistical model for short-term prediction of sea levels at high tide in the tide influenced part of the Weser ...
