(BLACKWELL, 2006-09-21)In this paper, we present the first BV I CCD photometry of six overlooked old open clusters (Berkeley 44, NGC 6827, Berkeley 52, Berkeley 56, Skiff 1 and Berkeley 5) and derive estimates of their fundamental parameters by ...
-
(2004-12-20)We measured the stellar velocity dispersions of 15 active galactic nucleus (AGN) host galaxies at redshifts as high as 0.34. Combining these with published velocity dispersion measurements from the literature, we study the ...
-
(Royal Soc, 2015)In this paper, both singular and hypersingular fundamental solutions of plane Cosserat elasticity are derived and given in a ready-to-use form. The hypersingular fundamental solutions allow to formulate the analogue of ...
-
(Elsevier, 2011)In this article we study basic properties for a class of nonlinear integral operators related to their fundamental solutions. Our goal is to establish Liouville type theorems: non-existence theorems for positive entire ...
-
(BLACKWELL SCIENCE LTD, 1999-10-11)We present the spectra and redshifts of 62 quasars, from observations made with the Cerro Tololo Inter-American Observatory (CTIO) 4-m Blanco Telescope. These quasars form part of a total sample of 118 (with 56 having been ...
-
(Elsevier, 2014)Face recognition is one of the most extensively studied topics in image analysis because of its wide range of possible applications such as in surveillance, access control, content-based video search, human–computer ...
-
(MDPI, 2020)The freezing level in the free troposphere often intercepts the terrain of the world's major mountain ranges, creating a rain-snow limit. In this work, we use the free tropospheric height of the 0 degrees C isotherm (H0) ...

(IEEE, 2010-02)The consideration of uncertainties in the future system operation is a key aspect in current planning methodologies. In this context, load flow studies based on probabilistic theory, fuzzy numbers, and Monte Carlo ...

(Springer Verlag, 2018)In this paper we propose to apply fuzzy logic methodologies for measuring key performance indicator into Balanced Scorecard (BSC) Customer Perspective. This study provide fuzzy key performance indicator (FKPI) to the ...

-
(Association for Computing Machinery, 2018)We report on a community effort between industry and academia to shape the future of graph query languages. We argue that existing graph database management systems should consider supporting a query language with two key ...
-
(Seismological Soc Amer, 2018)The importance of Global Navigation Satellite System (GNSS)-based earthquake early warning for modeling large earthquakes has been studied extensively over the past decade, and several such systems are currently under ...
-
(The American Astronomical Society., 2014-04-25)Despite their importance as stellar nurseries and the building blocks of galaxies, very little is known about the formation of the highest mass clusters. The dense clump G0.253+0.016 represents an example of a clump that ...
-
(The American Astronomical Society, 2015-01-20)We report molecular line observations, made with ASTE and SEST, and dust continuum observations at 0.87 mm, made with APEX, toward the cold dust core G305.136+0.068. The molecular observations show that the core is isolated ...
-
(IOP Publishing Ltd, 2018)Spectral line surveys reveal rich molecular reservoirs in G331.512-0.103, a compact radio source in the center of an energetic molecular outflow. In this first work, we analyze the physical conditions of the source by means ...
-
(EDP Sciences, 2016)Context. Ring-like structures in the interstellar medium (ISM) are commonly associated with high-mass stars. Kinematic studies of large structures in giant molecular clouds (GMCs) toward these ring-like structures may help ...
-
(ELSEVIER, 2006-09-01)Two lanthanide(III) complexes with L-glutamate ligands [{Ln(2)(L-Glu)(2)(H2O)(8)}center dot 4(ClO4)center dot 2.5H(2)O](n) (Ln = Gd (1), Eu (2)) have been prepared and characterized by single-crystal X-ray diffraction. The ...

(IOP PUBLISHING LTD, 2012-03-01)The ATLASGAL 870 mu m continuum survey conducted with the APEX telescope is the first one covering the whole inner Galactic plane (60 degrees > l > -60 degrees and b < +/-1 degrees.5) in submillimeter (submm) continuum ...
