2016/5/23
Electroabsorption (Stark effect) spectra are reported for the charge-transfer transitions of (NH3)5RuL2+ and [(NH3)5Ru]2L4+,5+, where L is pyrazine (pz) or 4,4'-bipyridine (4,4'-bpy). The spectra perm...
Direct Regression Modelling of High-order Moments in Big Data
Big data Higher-order moment U-statistics Estimating equation Divide-and-conquer
2016/1/20
Big data problems present great challenges to statisti-cal analyses, especially from the computational side. In this paper, we consider regression estimation of high-order mo-ments in big data problem...
MULTILEVEL OBJECT BASED IMAGE CLASSIFICATION OVER URBAN AREA BASED HIERARCHICAL IMAGE SEGMENTATION AND INVARIANT MOMENTS
hierarchical segmentation shape object-based classification invariant moments
2015/11/16
With the availability of very high resolution multispectral imagery from sensors such as IKONOS and Quickbird, it is possible to
identify small-scale features in urban environment. Because of the mu...
Fractional diffusion limit for collisional kinetic equations:A moments method
Kinetic equations linear Boltzmann equation asymptotic analysis diffusion limit anomalous diffusion limit fractional diffusion relaxation equation anomalous diffusive time scale
2015/10/15
This paper is devoted to hydrodynamic limits of linear kinetic equations. We consider situations in which the thermodynamical equilibrium is described by a heavy-tail distribution function rather than...
CONVERGENCE OF MOMENTS FOR DISPERSING BILLIARDS WITH CUSPS
Chaos decay of correlations Central Limit Theorem
2015/9/29
Dispersing billiards with cusps are deterministic dnamical systems with a mild degree of chaos, exhibiting “intermittent” behavior that alternates between regular and chaotic paterns.
The chapter discusses generalized method of moments (GMM) estimation
methods for spatial models. Much of the discussion is on GMM estimation of
Cliff-Ord-type models where spatial interactions are m...
Estimation of seismic moments from local magnitudes and coda durations for the Cairo earthquake aftershocks recorded at Kottamyia (KEG) Broadband station
aftershocks seismic moment scaling
2015/9/17
The spectral analysis of fifty-five KEG VBB records from the October 12, 1992 Cairo earthquake source region
was performed to obtain the seismic moment. We obtained this parameter in turn to develop ...
PLUME-MoM 1.0: A new integral model of volcanic plumes based on the method of moments
PLUME-MoM moments
2015/8/11
In this paper a new integral mathematical model
for volcanic plumes, named PLUME-MoM, is presented.
The model describes the steady-state dynamics of a plume
in a 3-D coordinate system, accounting f...

Sum rules for magnetic moments and polarizabilities in QED and chiral effective-field theory
Anomalous magnetic moment the cross section of discrete integral number arsene wenger reproduction
2014/12/20
We elaborate on a recently proposed extension of the Gerasimov-Drell-Hearn (GDH) sum rule which is achieved by taking derivatives with respect to the anomalous magnetic moment. The new sum rule featur...
Light baryon magnetic moments and N ->Delta gamma transition in a Lorentz covariant chiral quark approach
Magnetic moment light baryons lorentz covariance baryons bound state pseudo-scalar meson
2014/12/20
We calculate magnetic moments of light baryons and N→Δγ transition characteristics using a manifestly Lorentz covariant chiral quark approach for the study of baryons as bound states of constituent qu...
On the Positive Moments of Ranks of Partitions
rank of a partition k-marked Durfee symbol moment of ranks
2014/6/3
By introducing k-marked Durfee symbols, Andrews found a combinatorial interpretation of 2k-th symmetrized moment η2k(n) of ranks of partitions of n in terms of (k + 1)-marked Durfee symbols of n. In t...
