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...

Abstract This article offers a practical guide to analyzing vertical mergers using the general approach input foreclosure and raising rivals’ costs that is described in 2020 Vertical Merger Guidelines were issued by U.S. Department of Justice Federal Trade Commission. The step-by-step analysis here draws lessons from how theory harm played out lone merger case has been litigated antitrust agenc...

We have previously reported a standardized 10-step sequence of monoplane (transverse plane) transesophageal two-dimensional echocardiographic views and a standardized 7-step vertical plane examination, both suitable for expeditious intraoperative use by the beginning practitioner. A multiplane transesophageal examination involves transverse plane views, vertical plane views and the remaining "i...

A visibility representation of a graph maps vertices to horizontal segments and edges to vertical segments. For a weak-visibility representation, if the vertices of the original graph are adjacent, the corresponding segments will ’see’ each other. For a strong-visibility representation, the converse is true as well. Here we present a detailed step-by-step construction of a weak-visibility repre...

We present a fast and accurate numerical scheme for the approximation of the primitive equations of the atmosphere. The temporal variable is discretized by using a special semiimplicit scheme which requires only to solve a Helmholtz equation and a nonlocal Stokes problem at each time step; the spatial variables are discretized by a spectral-Galerkin procedure with the horizontal components of v...

Purpose: To compare the regularity and symmetry of gait between a cohort of older adults with bilateral knee osteoarthritis (OA) and an age and sex-matched control group of older adults with healthy knees. Methods: Fifteen (8 females) older adults with knee OA (64.7 ± 6.7 years) and fifteen (8 females) pain-free controls (66.1 ± 10.0 years) completed a 9-min. walk at a self-selected, comfortabl...

Turbulent heat transfer and hybrid Al2O3-Cu-nanofluid over vertical double forward facing-step is numerically conducted. The k-? standard model based on finite volume method in 2-D are applied to investigate the influences of Reynolds number, step height, fractions thermal performance. In this paper, different heights for three cases forward-facing adopted by five (Al2O3-Cu-water) nanofluid var...

Rhythmic sequences of steps and pools in steep mountain streams have captured the attention of numerous workers, but whether periodicities exist in the occurrence of step-pools has not been investigated in a comprehensive way, and the implications for such periodicities have not been explored. Spectral analysis was applied to bed elevation data from streams in the Santa Monica Mountains of sout...

Abnormal anti-pyramid MoS2/WS2 vertical heterostructures were synthesized by a facile single-step chemical vapour deposition.
