Solving the problem of stem contour extraction maize is difficult under open field conditions, and diameter cannot be measured quickly nondestructively. In this paper, at small large bell stages was object study. An adaptive threshold segmentation algorithm based on color space model proposed to obtain in field. Firstly, 2D images were captured with an RGB-D camera. Then, processed by hue satur...

In this investigation, the exact solutions of variable coefficients generalized Zakharov-Kuznetsov (ZK) equation and Gardner are studied with help an extended G ′ / expansion method. The main objective study is to establish closed-for...

This article investigates the local fractional generalized Kadomtsev–Petviashvili equation and Kadomtsev–Petviashvili-modified equal width equation. It presents traveling-wave transformation in a nondifferentiable type for governing equations, which translate them into ordinary differential equations. also solutions certain proposed models, using an ansatz method based on some functions defined...

In this study, we consider the stochastic Konno–Oono system to investigate soliton solutions under multiplicative sense. The noise is considered firstly in Stratonovich sense and secondly Ito^ Applications of include current-fed strings interacting with an external magnetic field. F-expansion method used find different types form dark, singular, complex combo, solitary, periodic, mixed rational...

Left ventricular cineangiograms (30 degrees right anterior oblique projection) and high fidelity left ventricular pressure were recorded at rest in 10 individuals with normal hearts and at rest and during an episode of angina provoked by rapid atrial pacing in 14 patients with obstructive coronary artery disease. Angiograms were digitised frame by frame. The ventricular perimeter was divided in...

The objective of this study was to establish a procedure for differentiating a baseline curve from a systematic deviation in weight-age data, and hence to develop a physiological growth model for the Thoroughbred. A total of 2,698 records for 175 foals was obtained during a period of 8 yr (1994 to 2001). Weight-age data were fit with a sigmoid growth equation, W = A(1 + be(-kt))M, where W is BW...

Sources of groundwater contaminants in inhabited areas, located complex geo-tectonic contexts, are often deeply interlocked, thus, making the discrimination between anthropic and natural origins difficult. In this study, we investigate Peloritani Mountain aquifers (Sicily, Italy), using combination probability plots with concentration contour maps to retrieve an overall view geo-chemistry a spe...

Abstract In this paper, a new complex waves representing solutions of the Ginzburg–Landau equation with Kerr law nonlinearity is investigated. we used extended rational sin–cos and sinh–cosh function methods construct precise to nonlinear equation. Bright periodic solution, dark wave soliton solution phenomena that occur in optics or plasma physics are obtained. The physical meaning geometrical...

The effects of manufacturing conditions on the microstructure evolution Ni-based superalloys are poorly understood, and interchangeable terminology to describe some phenomena is inconsistent. This critical review aimed address these issues through discussion seven that occur during thermomechanical processing safety-critical components used in jet engines. Each phenomenon outlined with referenc...
