Forward jet and particle production at HERA

DESY-HERA. H1 Collaboration. Study of Forward Jet and Particle Production in the Low x Region. Data comes from 1994 running period. Integrated luminosities are 2.8, 2.0 and 1.2 pb-1 for jets, PI0 and charged particle production respectively.

Molecular Packing in Unsubstituted Semiconducting Phenylenevinylene Oligomer and Polymer

p-Bis(p-styrylstyryl)benzene, C38H30, a five-ring phenylene−vinylene model compound for unsubstituted PPV, has been obtained in single-crystal form and the crystal structure has been resolved. The arrangement of the molecules is of the herringbone-type, and its characteristic dimensions correspond remarkably well to those of the structure proposed for PPV in 1986. This packing mode is entirely different from what has been found for substituted oligo(phenylenevinylene)s but similar to...

Global 30-Year Mean Monthly Climatology, 1930-1960, V2.1 (Cramer and Leeman)

Cramer, W.P.; Leemans, R. (1999)
Publisher: ORNL Distributed Active Archive Center
This database is a major update of the Leemans and Cramer database (Leemans and Cramer 1991). It currently contains monthly averages of mean temperature, temperature range, precipitation, rain days and sunshine hours for the terrestrial surface of the globe, gridded at 0.5 degree longitude/latitude resolution. It was generated from a large data base, using the partial thin-plate splining algorithm developed by Michael F. Hutchinson, Canberra (Hutchinson and Bischof 1983).

Diffractive dijet production at HERA

DESY-HERA. Measurement of diffractive dijet production differential cross sections in photoproduction and DIS events in which the hadronic final state containing the two jets is well seperated in rapidity from a leading baryonic system. This baryonic system is coded here as a proton and is defined as having a massless than 1.6 GeV. Analyses are performed of both resolved and direct photoprod uction and of DIS with photon virtualities in the Q**2 range 7.5 to 80 GeV.. In the following tables t...

Global Soil Types, 1-Degree Grid (Zobler)

ZOBLER, L. (1999)
Publisher: ORNL Distributed Active Archive Center
A global data set of soil types is available at 1-degree latitude by 1-degree longitude resolution. There are 26 soil units based on Zobler s assessment of FAO Soil Units (Zobler, 1986). The data set was compiled as part of an effort to improve modeling of the hydrologic cycle portion of global climate models. A more extensive version of these data, including 106 soil units as well as soil texture and slope, is available from NCAR, Scientific Computing Division, Data Support Section; the more...

Nexus - an open global infrastructure for spatial-aware applications

Hohl, Fritz; Kubach, Uwe; Leonhardi, Alexander; Rothermel, Kurt; Schwehm, Markus (1999)
Publisher: Universität Stuttgart
Embargo end date: 2016/03/31
Due to the lack of a generic platform for location- and spatial-aware systems, many basic services have to be reimplemented in each application that uses spatial-awareness. A cooperation among different applications is also difficult to achieve without a common platform. In this paper we present a platform that solves these problems. It provides an infrastructure that is based on computer models of regions of the physical world, which are augmented by virtual objects. We show how virtual obje...
