In the visual arts, gradation is the technique of gradually transitioning from one hue to another, or from one shade to another, or one texture to another. Space, distance, atmosphere, volume, and curved or rounded forms are some of the visual effects created with gradation. [1] A gradient illustration, showing a gradation spectrum from black ...
At each step, noise frequency is doubled and amplitude is halved. 2-D Perlin noise with a contour line at zero, showing that the noise is zero at the gradient mesh intersections. Perlin noise is most commonly implemented as a two-, three- or four-dimensional function, but can be defined for any number of dimensions. An implementation typically ...
Gradient noise is a type of noise commonly used as a procedural texture primitive in computer graphics. It is conceptually different from [further explanation needed
Noise in computer graphics refers to various pseudo-random functions used to create textures, including: Gradient noise, created by interpolation of a lattice of pseudorandom gradients Perlin noise, a type of gradient noise developed in 1983; Simplex noise, a method for constructing an n-dimensional noise function comparable to Perlin noise
A sound speed gradient leads to refraction of sound wavefronts in the direction of lower sound speed, causing the sound rays to follow a curved path. The radius of curvature of the sound path is inversely proportional to the gradient. [2] When the sun warms the Earth's surface, there is a negative temperature gradient in atmosphere.
Arts in education is an expanding field of educational research and practice informed by investigations into learning through arts experiences. In this context, the arts can include Performing arts education (dance, drama, music), literature and poetry, storytelling, Visual arts education in film, craft, design, digital arts, media and photography.

Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical ...
The speed has a weak dependence on frequency and pressure in dry air, deviating slightly from ideal behavior. In colloquial speech, speed of sound refers to the speed of sound waves in air. However, the speed of sound varies from substance to substance: typically, sound travels most slowly in gases, faster in liquids, and fastest in solids.
