Abstract. The spin structure of nucleon at twist 2 and 3 levels is analyzed. The contribution of quark and gluon spins to nucleon spin are Lorentz invariant, while it is not sure for orbital angular momentum. The conserved fractional moments of transversity distribution are considered. The scenario of decoupled total angular momentum, determined predominantly by the unpolarized scattering, is d...

We calculate the magnetic moments of heavy baryons with a single heavy quark in the boundstate approach. In this approach the heavy baryons is considered as a heavy meson bound in the field of a light baryon. The light baryon field is represented as a soliton excitation of the light pseudoscalar and vector meson fields. For these calculations we adopt a model that is both chirally invariant and...

This paper presents an efficient biometric algorithm for iris recognition using Fast Fourier Transform and moments. Biometric system provides automatic identification of an individual based on a unique feature or characteristic possessed by the individual. The Fast Fourier Transform converts image from spatial domain to frequency domain and also filters noise in the image giving more precise in...

We discuss experimental techniques for measurement of the density of beam particles in both the transverse and longitudinal phase space. The second moments of a two-dimensional density in conjugate coordinates are combined to form the emittance, which remains invariant under idealized beam transport. Four different methods of emittance measurement are presented, as will be implemented at the Br...

We compute the first two moments 〈(sH − mD 2)1,2〉 of the final hadronic invariant mass in the inclusive decay B → Xc l ν̄, in the presence of a cut E min l on the charged lepton energy. These moments may be measured directly by experiments at the Υ(4S) using the neutrino reconstruction technique, which requires such a cut. Measurement of these moments will place constraints on the nonperturbativ...

The analysis of time-dependent data is often guided by the question of how dominant structures develop over time. It is important to understand how patterns or structures identified for one time step evolve over time, by changing or moving in the domain. To gain insight into such evolving structural change it is crucial to effectively compare different time steps. This paper proposes a comparis...

We show that the magnetic moments of the octet baryons can be fitted to an accuracy of 1.5 % by a phenomenological Lagrangian in which SU(3) breaking corrections appear only linearly. This is in contrast to conventional chiral perturbation theory in which corrections non-analytic in SU(3) breaking dominate and tend to spoil the agreement with the data. Motivated by this observation, we propose ...

We compute the leading order (in α s) perturbative QCD and power (1/m 2 b) corrections to the hadronic invariant mass and hadron energy spectra in the decay B → X s ℓ + ℓ − in standard model. The computations are carried out using the heavy quark expansion technique (HQET) and a perturbative-QCD improved Fermi motion (FM) model which takes into account B-meson wave-function effects. The correct...

Analysis and interpretation of an image which was acquired by a non ideal imaging system is the key problem in many application areas. The observed image is usually corrupted by blurring, spatial degradations, and random noise. In this paper, we propose an alternative approach. We derive the features for image representation which are invariant with respect to blur regardless of the degradation...
