Cloudy bag model: Convergent perturbation expansion for the nucleon

The concept of chiral symmetry has been of great importance in elementary-particle physics for many years. ' ' In the context of massless quarks and quantum chromodynamics it is, of course, an exact symmetry, and should survive the proof of confinement in some way. It is not surprising, therefore, that immediately after the presentation of the original MIT bag model4 Chodos and Thorn' attempted...

Light Front Cloudy Bag Model: Nucleon Electromagnetic Form Factors

The nucleon is modeled, using light front dynamics, as a relativistic system of three bound constituent quarks emersed in a cloud of pions. The pionic cloud is important for understanding lowmomentum transfer physics, especially the neutron charge radius, but the quarks are dominant at high values of Q2. The model achieves a very good description of existing data for the four electromagnetic el...

SHDOMPPDA: A Radiative Transfer Model for Cloudy Sky Data Assimilation

The spherical harmonics discrete ordinate method for plane-parallel data assimilation (SHDOMPPDA) model is an unpolarized plane-parallel radiative transfer forward model, with corresponding tangent linear and adjoint models, suitable for use in assimilating cloudy sky visible and infrared radiances. It is derived from the spherical harmonics discrete ordinate method plane-parallel (SHDOMPP, als...

A cloudy fuzzy economic order quantity model for imperfect-quality items with allowable proportionate discounts

In the traditional economic order quantity/economic production quantity model, most of the items considered are of perfect type. But this situation rarely takes place in practice. Thus, in this paper, an economic order quantity model with imperfectquality items is developed. 100% screening process is performed, and the items of imperfect quality are sold as a single batch. A proportionate ra...
