Ground Penetrating Radar Imaging of an Aquifer During a Pumping Test

Abstract: We have imaged the temporal and spatial response of an unconfined aquifer during a pumping test using ground penetrating radar (GPR) profiling. In particular, we have observed the transient behavior of the reflection generated by the water content variation occurring in the transition zone between the overlying residually saturated material and the water saturated capillary fringe below. The progressive arrival time delay of this reflection was measured and used to infer its drawdown that occurred during the pumping test. We also observed several other phenomena on the GPR profiles that are related to drainage: (1) the development of a series of diffractions indicating localized irregularities in water saturation and (2) the velocity pull-up of stratigraphic reflections due to increased electromagnetic (EM) wave velocity in the overlying section. Comparing the GPR profiling data and piezometer measurements, we have observed that the drawdown of the transition zone reflection is smaller and delayed relative to the measured hydraulic head drawdown. From the combined GPR and piezometer data, we have inferred that a 0.20 m increase in the combined thickness of the transition zone and capillary fringe occurred before the drawdown of the GPR transition zone reflection commenced. Once achieved, this 0.20 m increased thickness remained for the duration of the pumping test. Using the distance-drawdown relationship obtained from GPR profiling, we have estimated the drained water volume due to the downward movement of the transition zone. The results of our analysis account for only a fraction of the pumping well production, approximately 45% on the first day and about 25% on the second day. Of the various reasons examined to explain this result, we have concluded that it is likely that the behavior of the GPR reflection originating from the transition zone is representative of the shallower, less saturated portion of the transition zone and undetected drainage is occurring in the deeper, more saturated portion of the transition zone.

Enterprise Resource Planning (ERP) Systems and the Manufacturing-Marketing Interface: An Information Processing Theory View

Abstract: The manufacturing–marketing interface has received substantial consideration in the operations management literature. However, relatively little attention has been paid to the role of information systems in facilitating manufacturing–marketing integration. As integrated cross-functional systems, enterprise resource planning (ERP) systems are well-suited to provide manufacturing–marketing integration. Based on information-processing theory, the central proposition of this paper is the greater the interdependence between manufacturing and marketing, the greater the benefit of ERP. Specifically, the first hypothesis (H1) states that the greater ERP-enabled coordination between manufacturing and marketing, the greater the benefit of ERP to the plant. The second hypothesis (H2) states that the degree to which ERP-enabled manufacturing–marketing coordination improvements are realized depends on the amount of interdependence between manufacturing and marketing. Using multiple regression, the model is tested on s...

A finite set of generators for the Kauffman bracket skein algebra

Abstract: If F is a compact orientable surface it is known that the Kauffman bracket skein module of \(F \times I\) has a multiplicative structure. Our central result is the construction of a finite set of knots which generate the module as an algebra. We can then define an integer valued invariant of compact orientable 3-manifolds which characterizes \(S^3\).

Police Work and Culture in a Nonurban Setting: An Ethnographic Analysis:

Abstract: This article represents the findings of an ethnographic analysis of police patrol activity in a nonurban setting. A growing body of research describes differences between urban and nonurban police work. However, the way officers think about their work in nonurban settings is relatively unstudied and is the purpose of this research. Data were collected through descriptions of the patrol setting and interviews of deputies. Findings showed support for themes of policing widely described in literature derived from urban-based research. However, the meanings associated with those themes sometimes differed from urban-associated research. At least in regard to the research setting considered here, generalizing from research conducted in urban settings would have resulted in the exclusion of meanings that capture important local dynamics.
