The element of value is compatible with the term luminosity, and can be "measured in various units designating electromagnetic radiation". [6] The difference in values is often called contrast , and references the lightest (white) and darkest (black) tones of a work of art, with an infinite number of grey variants in between. [ 6 ]
Circuits with only linear elements, linear circuits, do not cause intermodulation distortion and can be easily analysed with powerful mathematical techniques such as the Laplace transform. Nonlinear elements – these are elements in which the relation between voltage and current is a nonlinear function.
One of the most fundamental elements of art is the line. An important feature of a line is that it indicates the edge of a two-dimensional (flat) shape or a three-dimensional form. A shape can be indicated by means of an outline, and a three-dimensional form can be indicated by contour lines. [1]
In contrast, a nonlinear element's behavior is specified by its detailed transfer function, which may be given by a curved line on a graph. So specifying the characteristics of a nonlinear circuit requires more information than is needed for a linear circuit. "Linear" circuits and systems form a separate category within electronic manufacturing.
In many materials the polarizability starts to saturate at high values of electric field. This saturation can be modelled by a nonlinear susceptibility. These susceptibilities are important in nonlinear optics and lead to effects such as second-harmonic generation (such as used to convert infrared light into visible light, in green laser pointers).
One currently active field of research is the use of linear optics versus the use of nonlinear optics in quantum computing.For example, one model of linear optical quantum computing, the KLM model, is universal for quantum computing, and another model, the boson sampling-based model, is believed to be non-universal (for quantum computing) yet still seems to be able to solve some problems ...
The central visual element, known as element of design, formal element, or element of art, constitute the vocabulary with which the visual artist compose. These elements in the overall design usually relate to each other and to the whole art work. The elements of design are: Line — the visual path that enables the eye to move within the piece
A form is an artist's way of using elements of art, principles of design, and media. Form, as an element of art, is three-dimensional and encloses space. Like a shape, a form has length and width, but it also has depth. Forms are either geometric or free-form, and can be symmetrical or asymmetrical.
