Quick regional centroid moment tensor solutions for the Emilia 2012 (northern Italy) seismic sequence
Earthquake source Seismic moment tensor Wave analysis Data processing
2015/8/26
In May 2012, a seismic sequence struck the Emilia region (northern Italy). The mainshock, of Ml 5.9, occurred on May 20, 2012, at 02:03 UTC. This was preceded by a smaller Ml 4.1 foreshock some hours ...
Perceiving the centroid of configurations on a rolling wheel
Perceiving centroid configurations rolling wheel
2015/8/14
Undergraduates observed configurations of point-lights undergoing wheel-generated motions and judged how wheel-like the movement of each stimulus appeared on a 7-point scale. Viewer judgments were pre...

Perceiving centroid curvilinearly bounded rolling shapes
2015/8/14
Although its absolute motion is the same, the path of a single moving point is often perceived differ-ently when viewed alone than when viewed as a part of a dynamic configuration of many points.A poi...
Astrometric Image Centroid Displacements due to Gravitational Microlensing by the Ellis Wormhole
Astrometric Image Centroid Displacements due to Gravitational Microlensing by the Ellis Wormhole
2011/10/17
Continuing work initiated in an earlier publication (Abe, ApJ, 725 (2010) 787), we study the gravitational microlensing effects of the Ellis wormhole in the weak-field limit. First, we find a suitable...

Abstract: We show that the rate of convergence on the approximation of volumes of a convex symmetric polytope P in R^n by its dual L_{p$-centroid bodies is independent of the geometry of P. In particu...

Security issues are crucial in a number of machine learning applications, especially in
scenarios dealing with human activity rather than natural phenomena (e.g., information
ranking, spam detection...
Optimal properties of centroid-based classifiers for very high-dimensional data
Centroid method classification discrimination distance-basedclassifiers high-dimensional data location differences minimax performance
2010/3/11
We show that scale-adjusted versions of the centroid-based classi-
fier enjoys optimal properties when used to discriminate between two
very high-dimensional populations where the principal differen...
A centroid-based performance evaluation using aggregated fuzzy numbers
Aggregated fuzzy numbers centroid index
2010/9/15
In recent years, some methods have been proposed in solving performance evaluation issues by using fuzzy set theory. In this paper, an improvised method for performance evaluation under fuzzy environm...
Quantum Imaging beyond the Diffraction Limit by Optical Centroid Measurements
Quantum Imaging Diffraction Limit Optical Centroid Measurements
2010/4/12
I propose a quantum imaging method that can beat the Rayleigh-Abbe diffraction limit and achieve de Broglie resolution without requiring a multiphoton absorber as the detector. Using the same non-clas...
Optimum Condition of High Pressure Treatment for the Preparation of Lysozyme-Dextran Complex Found by Random-Centroid Optimization
lysozyme-dextran complex high pressure random-centroid optimization
2009/6/18
The lysozyme-dextran complex (LDC) was prepared in the liquid state using high pressure treatment. This method was able to shorten the reaction period for the preparation of LDC and to suppress the fo...
Upright immersion imposes a pressure imbalance between alveolar and mean external thoracic pressure. Lung centroid pressure (PLC) is defined as the breathing pressure required to remove this imbalan...
The stability of anatomical and centroid reference points in cephalometric analysis
Cephalometrics Variation Centroid Reference points
2009/1/23
Cephalometric records of 60 fetuses were combined on a coordinate reference grid to measure the statistical spread of the outlines. When centroid instead of anatomical points were used for superimpo...

2009/1/12
To overcome the problem of variation of reference points in cephalometric analysis two methods have been used: 1) fixed relations between consistently recognizable anatomical points and 2) centers...

2008/11/18
The centroid motion of the Western Pacific warm pool for 1982–83, 1986–87 and 1991–93 El Niño–Southern Oscillation events was investigated by analyzing satellite multichannel sea surface temper...
