in nuclear medicine, there are two methods of imaging, planar and tomography. single photon emission computerized tomography (spect) shows better image details and therefore is influenced more by image parameters such as resolution, uniformity, sensitivity, etc. manufacturers provide customers with data which are obtained by complicated and sometimes secret methods. marketing companies test and...

In this paper we introduce an adaptive recommender system that supports the user in finding interesting entries in an electronic product catalog. The Analytic Hierarchy Process (AHP) lays the foundation for the user preferences. The user interests are specified in terms of desired properties of the ideal product, expressed in the form of constraints (or criteria) on the products basic attribute...

The Swiss avalanche bulletin is produced twice a day in four languages. Due to the lack of time available for manual translation, a fully automated translation system is employed, based on a catalogue of predefined phrases and predetermined rules of how these phrases can be combined to produce sentences. Because this catalogue of phrases is limited to a small sublanguage, the system is able to ...

Context. A new reduction of the astrometric data as produced by the Hipparcos mission has been published, claiming accuracies for nearly all stars brighter than magnitude Hp = 8 to be better, by up to a factor 4, than in the original catalogue. Aims. The new Hipparcos astrometric catalogue is checked for the quality of the data and the consistency of the formal errors as well as the possible pr...

We present a catalogue of 6206 stars which have proper motions exceeding 0.18yr with an R-band faint magnitude limit of 19·5mag. This catalogue has been produced using SuperCOSMOS digitized R-Band ESO and UK Schmidt Plates in 131 Schmidt fields covering more than 3,000 square degrees (>7·5% of the whole sky) at the South Galactic Cap. The survey is ≥90% complete within the nominal limits of the...

We present Strr omgren uvby and H photometry for a set of 575 northern main sequence A type stars, most of them belonging to the Hipparcos Input Catalogue, with V from 5 m to 10 m and with known radial velocities. These observations enlarge the catalogue we began to compile some years ago to more than 1500 stars. Our catalogue includes kinematic and astrophysical data for each star. Our future ...

As of spring semester 2010, Georgia Southern University began using a VuFind implementation as the default access to the library catalogue on the library Web page while maintaining a secondary link to the traditional Voyager “classic” catalogue. VuFind is an opensource product that has been adopted and adapted by all the state universities and colleges in the state of Georgia. For approximately...
