Migratory birds use multiple sources of compass information for orientation, including the geomagnetic field, the sun, skylight polarization patterns and star patterns. In this paper we review the results of cue-conflict experiments designed to determine the relative importance of the different compass mechanisms, and how directional information from these compass mechanisms is integrated. We f...

This paper describes the context-aware mobile tourist application COMPASS that adapts its services to the user’s needs based on both the user’s interests and his current context. In order to provide context-aware recommendations, a recommender system has been integrated with a contextaware application platform. We describe how this integration has been accomplished and how users feel about such...

The new COMPASS ∆G/G result obtained from high transverse momentum hadron pairs in the Q > 1 (GeV/c) region is presented. Comparing to the previous analysis in this region the statistical error of ∆G/G is reduced by a factor 3 to 0.10. A weighted method of the ∆G/G measurement based on neural network approach is used. In addition, the formula for the ∆G/G extraction used in the analysis has bee...

After pioneering works on hypernuclei, strangeness production mechanisms have been studied in hadron collisions and photoreactions in the sixties. Recent experiments at SATURNE and COSY, in the hadronic sector, as well as ELSA and JLab, in the electromagnetic sector, have confirmed our basic ideas on the reaction mechanisms. In the near future, strangeness production at JLab, HERMES and COMPASS...

This paper reports on work performed in the context of the COMPASS SESAR-JU WP-E project, on developing an approach for identifying and filtering inaccurate trajectories (ghost flights) in historical data originating from the EUROCONTROLoperated Demand Data Repository (DDR). Foreword—This paper describes a project that is part of SESAR Workpackage E, which is addressing long-term and innovative...

SUMMARY G-compass is designed for efficient comparative genome analysis between human and other vertebrate genomes. The current version of G-compass allows us to browse two corresponding genomic regions between human and another species in parallel. One-to-one evolutionarily conserved regions (i.e. orthologous regions) between species are highlighted along the genomes. Information such as locat...

ETRI Journal, Volume 27, Number 3, June 2005 This paper presents an efficient algorithm for using the two-axis magnetic compass in portable devices. The general magnetic compass module consists of a three-axis magnetic compass and a two-axis inclinometer to calculate tilt-compensated azimuth information. In this paper, the tilt error is compensated using just a two-axis magnetic compass and two...

Transversity and transverse momentum-dependent parton distribution functions (TMDs) are been measured in semi-inclusive deep inelastic scattering (SIDIS) by using a transversely polarized target at the COMPASS experiment. COMPASS is a fixed target experiment at the CERN M2 beamline, which provides a 160 GeV/c polarized μ+ beam. In the years 2002-2004 COMPASS has collected data with a transverse...

We demonstrate a prototype of the tablet-based L2 grammar teaching system COMPASS III. COMPASS stands for COMbinatorial and Paraphrastic Assembly of Sentence Structure; for a description of the underlying computational-linguistic software, see [1]. COMPASS invites the student to construct sentences by composing syntactic trees out of lexically anchored “treelets” via the graphical drag&drop use...
