Pumping tests carried out in the fissured layer of a granitic hard-rock aquifer, interpreted at the observation wells by means of the analytical solution of Neuman and at the pumping wells using that one of Gringarten show the vertical anisotropy of this layer of the aquifer; the horizontal permeability being clearly and systematically higher than the vertical permeability. These results perfec...

The general relativistic model of Cooperstock & Tieu, which attempts to fit rotation curves of spiral galaxies without invoking dark matter, is tested empirically using observations of the Milky Way. In particular, predictions for the mass density in the solar neighbourhood and the vertical density distribution at the position of the Sun are compared with observations. It is shown that the mode...

A spatial coherenceies of SR beam at visible light region were measured both σ and π-polarized components at Photon Factory. A wave-front division type polarized interferometer was designed and constructed for this experiment. Interferograms were observed clearly in the vertical direction. π phase difference of the interference fringe was observed between interferograms corresponding to σ and π...

Trace gas profile retrieval constitutes an ill-posed inverse problem. This paper explores the potential of the application of neural networks for the retrieval of methane vertical column densities from remote sensed radiances. Three types of neural networks have been tested using noiseless and noisy data. Here we focused on the reconstruction of vertical column densities using SCIAMACHY channel...

High resolution vertical distributions of chlorophyll and zooplankton were collected with an instrumented Batfish vehicle in northeastern Baffin Bay. The dominant copepod species wc1.e Calanusfinmllrchicus, Calanus glncinlis, and Calanus hyperlporeus V and VI. Copepod layers consisting of C. jkmclr-chicus and C. glncialis were commonly situated ~3-4 m above the chlorophyll maximum in a depth re...

Nonequilibrium dc and large-signal ac vertical electron transport in GaN/AlGaN heterostructures is investigated by Monte Carlo simulations. The symmetric two-barrier GaN/AlGaN heterostructures are studied. The results of simulations show that polarization charges have a profound effect on dc and large-signal ac characteristics of vertical electron transport in GaN/AlGaN heterostructures. Under ...

The vertical distribution of three minor atmospheric constituents (O 3 , N 2 O, HNO 3 ) has been obtained from far infrared limb thermal emission in the 22-24 cm spectral region. Measurement were made with a high resolution interferometer on a balloon payload launched on July 29, 2002 from Trapani (Sicily). Several limb scan sequences have been analysed and the resulting profiles have been comp...

A two-dimensional dust crystal levitated in the sheath of a modified Gaseous Electronics Conference (GEC) reference cell is manipulated by heating or cooling the lower electrode. The dust charge is obtained from top-view pictures of the crystal using a previously developed analytical model. By assuming a simple force balance, and measuring the radial confining force, the vertical electric field...

Quality of life improves after bariatric surgery. However, long-term results and the influence of reoperations are not well known. A prospective quality of life assessment before, 1 and 7 years after laparoscopic adjustable gastric banding (LAGB) and vertical banded gastroplasty (VBG) was performed in order to determine the influence of reoperations during follow-up. One hundred patients were i...

One advantage of smart grids is that they can reduce the peak load by distributing electricity-demands over multiple short intervals. Finding a schedule that minimizes the peak load corresponds to a variant of a strip packing problem. Normally, for strip packing problems, a given set of axis-aligned rectangles must be packed into a fixed-width strip, and the goal is to minimize the height of th...
