Wake flowfields for Jovian probe
The wake flow field developed by the Galileo probe as it enters the Jovian atmosphere was modeled. The wake produced by the probe is highly energetic, yielding both convective and radiative heat inputs to the base of the probe. A component mathematical model for the inviscid near and far wake, the viscous near and far wake, and near wake recirculation zone was developed. Equilibrium thermodynamics were used for both the ablation and atmospheric species. Flow fields for three entry conditions were calculated. The near viscous wave was found to exhibit a variable axial pressure distribution with the neck pressure approximately three times the base pressure. Peak wake flow field temperatures were found to be in proportion to forebody post shock temperatures

The thesis writing here is an effort by the artist to identify his motives in creating, and his aims for the audience, and to communicate this to the reader in a clear and truthful manner. Section 1 focuses on introducing the ground of the artists’ thinking, discussing his ideas of the body and culture identity, and how they motivate his work. Section 2 goes into greater detail about the manner his thought process evolved through the course of a number of works. In Section 3, there is an ever sharper focus in the works towards the isolated and inscrutable individual. The theme that runs throughout is that, although it’s difficult if not impossible to fully communicate with another, the effort is worthwhile

A Review and Outlook for the Removal of Radon-Generated Po-210 Surface Contamination
The next generation low-background detectors operating deep underground aim
for unprecedented low levels of radioactive backgrounds. The deposition and
presence of radon progeny on detector surfaces is an added source of energetic
background events. In addition to limiting the detector material's radon
exposure in order to reduce potential surface backgrounds, it is just as
important to clean surfaces to remove inevitable contamination. Such studies of
radon progeny removal have generally found that a form of etching is effective
at removing some of the progeny (Bi and Pb), however more aggressive
techniques, including electropolishing, have been shown to effectively remove
the Po atoms. In the absence of an aggressive etch, a significant fraction of
the Po atoms are believed to either remain behind within the surface or
redeposit from the etching solution back onto the surface. We explore the
chemical nature of the aqueous Po ions and the effect of the oxidation state of
Po to maximize the Po ions remaining in the etching solution of contaminated Cu
surfaces. We present a review of the previous studies of surface radon progeny
removal and our findings on the role of oxidizing agents and a cell potential
in the preparation of a clean etching technique.Comment: Proceedings of the Low Radioactivity Techniques (LRT) 2017, Seoul,

Brownian Dynamics of a Sphere Between Parallel Walls
We describe direct imaging measurements of a colloidal sphere's diffusion
between two parallel surfaces. The dynamics of this deceptively simple
hydrodynamically coupled system have proved difficult to analyze. Comparison
with approximate formulations of a confined sphere's hydrodynamic mobility
reveals good agreement with both a leading-order superposition approximation as
well as a more general all-images stokeslet analysis.Comment: 4 pages, 3 figures, REVTeX with PostScript figure
The moderating effect of brand orientation on inter-firm market orientation and performance
While prior research has shown that market and brand orientation
are key contributors to successful business performance, research to
date has not fully explored how inter firm collaboration for these two
key orientations can enhance business performance. The purpose of
the paper is to investigate the relationship between inter-firm market
and performance; to test for the moderating role of brand orientation
in that relationship. A total of 169 completed pairs of surveys were
collected of small and medium enterprises operating internationally
in a variety of industries in Switzerland. The results show that inter-firm
market and brand orientation are two antecedents of marketing and
financial performance. The impact of inter-firm market on marketing
and financial performance is significant when the brand orientation
is favorable. This study extends previous research by examining the
moderating role of brand orientation on inter firm market orientation,
which is important, especially for firms wanting to increase their brand
reputation by entering into partnerships with other firms. Further
research is indicated, to identify the key moderators of the driving
force of inter-firm market in relation to business performance and
the reason why maintaining a strong brand presence is important in
the international marketplace
