Parallel processor for fast event analysis

Current maximum data rates from the Spin Spectrometer of approx. 5000 events/s (up to 1.3 MBytes/s) and minimum analysis requiring at least 3000 operations/event require a CPU cycle time near 70 ns. In order to achieve an effective cycle time of 70 ns, a parallel processing device is proposed where up to 4 independent processors will be implemented in parallel. The individual processors are designed around the Am2910 Microsequencer, the AM29116 ..mu..P, and the Am29517 Multiplier. Satellite histogramming in a mass memory system will be managed by a commercial 16-bit ..mu..P system

Supporting ethical, independent learning behavior among university students in the Arabian Gulf

© Springer International Publishing Switzerland 2014. Students in the Arabian Gulf region and the world over confront plagiarism temptations wittingly or unwittingly due to the multitude of free and easily available electronic sources of information. Rather than develop independent learning skills and academic integrity, students are often taken advantage of by essay mills that sell readymade essays. Instructors at times compound the problem by repeatedly recycling course assignments and tasks. Furthermore, there have been reports of the use of social networking sites for outsourcing and contract cheating in student assignments. This paper discusses how educators in an institution of higher learning in the UAE assist students to develop good academic skills. Data collection is with the use of an online survey questionnaire. Concurring with Wheeler and Anderson (2010) who call for appropriate and comprehensive institutional policies and guidelines for dealing with plagiarism, practical examples of the processes and procedures used at these institutions are provided

ASASSN-15lu is a Type Ia Supernova

We report spectroscopic classification of ASASSN-15lu (ATel #7698) in SDSS J132112.88+401556.7 (z=0.035037, via NED) through inspection of an optical spectrum (range 370-680 nm, resolution 0.8 nm), obtained with the 2.3-m Bok telescope (+ Boller & Chivens spectrograph) at Kitt Peak on 2015 June 24.2 UT

An overview of the ORNL-NFS intercomparison

Nuclear Fuel Services sent more than 800 drums of nuclear waste to Oak Ridge National Laboratory, with the majority of the waste packaged into five different waste matrix types. A thorough and complete assay of the waste was performed at both NFS and at ORNL. A detailed comparing of the two assay sets provides valuable. insights into problems encountered in typical assay campaigns, particularly as there is, for the most part, excellent agreement between these two campaigns

Data acquisition system for the HHIRF spin spectrometer

The Spin Spectrometer at the Holifield Heavy Ion Research Facility (HHIRF) is a multidetector ..gamma..-ray spectrometer consisting of 72 separate NaI detector elements closely packed in a 4..pi.. geometry. The basic apparatus was constructed at Washington University and has been installed and implemented at the HHIRF at Oak Ridge National Laboratory. The spectrometer was designed especially for the investigation of the mechanisms of heavy-ion induced nuclear reactions and of the structure of nuclei with high angular momentum. The data acquisition system is described. (WHK

Proposed design for a fast (parallel) preprocessor for the spin spectrometer and other eventful albatrosses

Because devices like the Spin Spectrometer described in a previous paper to this conference can produce an extremely fast but fairly simple-to-process data stream, it seems reasonable to consider front-end preprocessors having special characteristics. In general, the kinds of transformations being considered do not require floating point calculations or extensive calculations. In order to be somewhat specific, the particular data acquisition/processing problems posed by the Spin Spectrometer at the Holifield Heavy Ion Facility will be discussed
