Fractured-rock aquifers display spatially and temporally variable hydraulic conductivity generally attributed to variable fracture intensity and connectivity. Empirical evidence suggests fracture aperture and hydraulic conductivity are sensitive to in situ stress. This study investigates the sensitivity of fractured-rock hydraulic conductivity, groundwater flow paths, and advectiondominated tra...

This paper deals with waves propagating in a one-dimensional flow moving through a randomly layered medium. The flow velocity is assumed to be greater than the group velocity of the waves in the reference system of the flow. As a result, in the laboratory reference system, all the waves propagate in a single direction. Amplitudes of these waves moving through a randomly inhomogeneous medium are...

For object classification in video surveillance, features extracted from images are compared with a visual dictionary. The best-matching features are learned by the classifier to determine the object class. In this paper, the visual dictionary concept is extended with Interest Point Operators (IPOs). In a first experiment, the influence of using IPOs on the visual dictionary creation process is...

We give the equations governing the shear evolution in Bianchi spacetimes for general f(R)-theories of gravity. We consider the case of R-gravity and perform a detailed analysis of the dynamics in Bianchi I cosmologies which exhibit local rotational symmetry. We find exact solutions and study their behaviour and stability in terms of the values of the parameter n. In particular, we found a set ...

Using advanced Laser spectroscopy methods, nuclear ground state spins, moments, charge radii, of radioactive nuclei can be determined. The optical techniques, based on hyperfine structure splitting (HFS) or isotope shift measurements, yield model-independent information about the nucleus. Various experimental methods and concepts are proposed to take advantage of the exotic nuclei provided at l...

We present a FORTRAN-77 program to estimate the optimal depth of the source of anisotropy using spatial coherency of teleseismic shear-wave splitting (SWS) parameters. For a given assumed depth of anisotropy, the program computes a variation factor which is a weighted sum of the arithmetic standard deviation (SD) of the splitting times and the circular SD of the fast directions over overlapping...

Although the rhesus monkey (Macaca mulatta) was the first laboratory animal found to be suitable for experimental work with the virus of yellow fever (1, 2), the laboratory mouse has also played an important rble in yellow fever research. However, efforts to define more exactly the susceptibility of this animal have been few since the initial demonstration in 1930 that mice could be infected (3...

Case, it is not licensed due to the Case Filter under the GB framework. Thus BG intends to capture the relation between the accusative Case assignment and the -role assignment. In terms of the conceptual perspective, BG has been criticized for damaging the modular organization of the grammar (see McFadden 2004, Reuland (2000) for more discussions). For example, Haider (2000:33) points out that...

The overriding aim of this survey was to identify motivational, volitional and emotional predictors and correlates of PC and Internet literacy. Basic variables of self-regulated learning were of special interest here. Two studies were conducted during the testing phase of Webbased trainings for key competencies at three Universities in Northern Germany between 2002 and 2003. Study 1 (2002, n = ...
