In this paper, the author investigates a generic type of the two dimensional incompressible viscous boundary layer flows near the inflection point of a smooth curve. In particular, an approximate evaluation of velocity distribution in an “adjacent” region of the inflection point of this curve is derived. Here, it is a priory assumed that this point is unique. Besides, the flow field is supposed...

soil quality is a necessary indicator of land management. different indices are applied to evaluate farming systems, soil types and land uses based on soil quality. the slope of retention curve at its inflection point has been defined as soil physical quality index (si) but the relationships between si and penetration resistance (pr), the least limiting water range (llwr), and available water c...

An Inflection Point The tablet PC should provide the inflection point, the technological break that will provide the combination of portability and screen space required for real-life clinical use. Unlike a laptop, it can be held in one’s arm like the metal jacket of a patient chart, with data entered with a penlike device. This completely replicates the mode of data collection physicians have ...

We investigate the possibility to induce double peaks of gravitational wave(GW) spectrum from primordial scalar perturbations in inflationary models with three inflection points.Where points can be generated a polynomial potential or Higgs like $\phi^4$ running quartic coupling.In such models, point at large scales predicts spectral index and tensor-to-scalar ratio consistent current CMB constr...

We describe a model for tree crown extraction from aerial images, a problem of great practical importance for the forestry industry. The novelty lies in the prior model of the region occupied by tree crowns in the image, which is a phase field version of the higher-order active contour inflection point ‘gas of circles’ model. The model combines the strengths of the inflection point model with t...

This paper investigates the inflection-point instability that governs the flow disturbance initiated in the entrance region of a pulsating pipe flow. Under such a flow condition, the flow instability grows within a certain phase region in a pulsating cycle, during which the inflection point in the unsteady mean flow lifts away from the viscous effect-dominated region known as the Stokes layer. ...

Based on the reported data until 18 March 2015 and numerical fitting via a simple formula of cumulative case number, we provide real-time estimation on basic reproduction number, inflection point, peak time and final outbreak size of ongoing Ebola outbreak in West Africa. From our simulation, we conclude that the first wave has passed its inflection point and predict that a second epidemic wave...
