This paper presented a two step method for offline handwritten Farsi word recognition. In first step, in order to improve the recognition accuracy and speed, an algorithm proposed for initial eliminating lexicon entries unlikely to match the input image. For lexicon reduction, the words of lexicon are clustered using ISOCLUS and Hierarchal clustering algorithm. Clustering is based on the featur...
Objective Aspirated ovarian follicular fluids (FF) contain luteal granulosa cells (LGC) and other contaminating cell types. Several strategies such as the antibody binding methods, the flask method, the cell strainer, and the positive selection of granulosa aggregates after density gradient centrifugation, were tested as LGCs purification methods. Each of these strategies has its own advantages...
in this paper, the combined effect of suspended (fine dust) particles and rotation on the onset of thermosolutal convection in an elastico-viscous fluid in a porous medium is studied. for the porous medium, the brinkman model is employed and rivlin-ericksen model is used to characterize viscoelastic fluid. by applying normal mode analysis method, the dispersion relation has been derived and sol...
In this paper, a size-dependent first-order shear deformation plate model is formulated in the framework of the higher-order generalized nonlocal strain-gradient (GNSG) theory. This modelemploys ...
Composite optimization offers a powerful modeling tool for variety of applications and is often numerically solved by means proximal gradient methods. In this paper, we consider fully nonconvex composite problems under only local Lipschitz continuity the smooth part objective function. We investigate an adaptive scheme PANOC-type methods (Stella et al. in Proceedings IEEE 56th CDC, 1939--1944, ...
