Character segmentation is an important step in License Plate Recognition (LPR) system. There are many difficulties in this step, such as the influence of image noise, plate frame, rivet, the space mark, and so on. This paper presents a new algorithm for character segmentation, using Hough transformation and the prior knowledge in horizontal and vertical segmentation respectively. Furthermore, a...

The loss of the buccal alveolar plate following tooth extraction in the maxillary anterior region is an especially challenging condition for the clinician. Immediate implant placement with a flapless approach has been suggested in order to reduce postextraction bone loss. In the presence of a significant vertical gap in the buccal plate after tooth extraction, most authors still recommend a bon...

A suction/injection controlled free convection motion of a viscous incompressible fluid past an infinite permeable vertical plate considered. The expression for temperature and velocity fields obtained and using laplace transform technique. The influence of each variable parameter is discussed with the aid of graphs. It is found that temperature is higher near the plate with injection while vel...

Aisha Rafi ,Vivek Kumar Sharma Department of mathematics, Jagan-Nath University, Jaipur, India. __________________________________________________________________________________________ Abstract A study of the free convective flow of a viscous fluid past a hot vertical porous plate is done with the assumption that the suction velocity is constant and normal to the plate and the plate temperatu...

This paper reviews results about free convection near a vertical flat plate embedded in some saturated porous medium. We focus on a third order autonomous differential equation that gives a special class of solutions called similarity solutions. Two cases are under consideration: in the first one we prescribe the temperature on the plate and in the second one we prescribe the heat flux on it. W...

The aim of the study is to describe the differentiation of the cortical plate in human foetuses aged 9-11 weeks. Histological sections showed that in this early period of development the cortical plate is differentiated into two zones. The external zone is composed of vertical columns of cells, which are perpendicular to the cortical surface. The internal zone is wider and consists of irregular...

A submerged horizontal plate type breakwater is pointed out as an efficient wave protection device for cage culture in marine fishery. In order to reveal the wave elimination principle of this type breakwater, boundary element method is utilized to investigate this problem. The flow field and the trajectory of water particles are studied carefully. The flow field analysis shows that: the intera...

Abstract-A numerical solution for the free convection flow past a vertical semi-infinite flat plate embedded in a highly saturated porous medium by allowing the plate to have a non-uniform temperature or a non-uniform heat flux distributions has been developed. Both local heat transfer rate and excess surface temperature as a function of the distance along the plate are tabulated for a few case...

An analysis is performed to study the unsteady flow past an exponentially accelerated infinite vertical plate with variable temperature and uniform mass diffusion, in the presence of a homogeneous chemical reaction of first-order. The plate temperature is raised linearly with time and the concentration level near the plate is raised uniformly. The dimensionless governing equations are solved us...

We present a case of rare pitfall in the diagnosis of an oesophageal foreign body due to the calcified vertical plate of the cricoid to highlight the need to be aware of this entity to avoid unnecessary morbidity.
