The gradient (also called slope) of a line tells us how steep it is.To find the gradient:Divide the vertical change (how far it goes up or down) by the horizontal change (how far it moves sideways).Gradient = C
Heat conduction is governed by the law of heat conduction, which is also called the Fourier's law: the time rate of heat transfer through a material is proportional to the negative gradient in the temperature and to the area. From: Finite Element Analysis Applications, 2018 ...
In nature, honeybees that frequently shuttle through pollen-rich flowers15provide a well-known example of manipulation of microscale particles. During foraging, honeybees are contaminated by microscale particles such as pollen and dust. These contaminants, if not swiftly removed, can lead to the obst...
the graph of alinear function 是一条直线line,这条直线的函数表达式也称作直线方程Equations of a straight line,斜截式gradient-intercept form是y=ka+b,其中常数k称为这条直线的斜率gradient,b称为这条直线的y截距y-intercept。我们需要知道的是:
The abundance of a specialized olive pest was lower in landscapes with higher woodland cover. The negative effects of intensification were stronger in spring and summer than in autumn, and parasitoids and predators were particularly affected. Overall, results suggest that retaining herbaceous cover, ...
one of the most severely hit country in the world, to identify a negative relationship between income andexcess mortalitywithin urban areas, that persists over COVID-19 waves. Over the year 2020, the poorest municipalities experienced a 30% higher increase in excess mortality. Our analyses can ...
X = X + a*dX; wheredXis the search direction. The parameterais selected to minimize the performance along the search direction. The line search functionsearchFcnis used to locate the minimum point. The first search direction is the negative of the gradient of performance. In succeeding iterati...
Hence, outliers, or isolated objects, could be improperly modelled in presence of the exclusivity assumption. A popular way to circumvent the difficulties of binary optimization is to relax the binary constraint into a nonnegative and/or orthogonal one (cf. Sect. 3.2). However, the resulting ...
Inspired by gradient materials in nature, advanced engineering components with controlled structural gradients have attracted substantial research interests due to their exceptional combinations of properties. However, it remains challenging to generate
A singularity-free generalisation of Newtonian gravity can be constructed (Lazar in Phys Rev D 102:096002, 2020) within the framework of gradient field theory. This procedure offers a straightforward regularisation of Newtonian gravity and remains equall
