Dirichlet form. In potential theory (the study of harmonic function) and functional analysis, Dirichlet forms generalize the Laplacian (the mathematical operator on scalar fields). Dirichlet forms can be defined on any measure space, without the need for mentioning partial derivatives. This allows mathematicians to study the Laplace equation ...
Free-Form Select (with synonyms) is a technique in printmaking, graphic design and image processing. The effect is to erase background colors or elements from a motif to create stand-alone objects. Today, this is done with graphics software ( computer graphics ) and computers rather than by cutting away parts with scissors or scalpels .
Translation operator (quantum mechanics) In quantum mechanics, a translation operator is defined as an operator which shifts particles and fields by a certain amount in a certain direction. It is a special case of the shift operator from functional analysis. More specifically, for any displacement vector , there is a corresponding translation ...
Freeform surface modelling is a technique for engineering freeform surfaces with a CAD or CAID system.. The technology has encompassed two main fields. Either creating aesthetic surfaces (class A surfaces) that also perform a function; for example, car bodies and consumer product outer forms, or technical surfaces for components such as gas turbine blades and other fluid dynamic engineering ...
On Monday, Nov. 13, the first 500 guests who visit each participating Krispy Kreme shop in the United States can snag a dozen Original Glazed Donuts for FREE, with no purchase necessary.
Momentum operator. In quantum mechanics, the momentum operator is the operator associated with the linear momentum. The momentum operator is, in the position representation, an example of a differential operator. For the case of one particle in one spatial dimension, the definition is: where ħ is Planck's reduced constant, i the imaginary unit ...
PDF Tools allows creation of PDFs from many types of source input (images, scans, etc.). The PDF-XChange print driver allows printing directly to a PDF. A "lite" version of the print driver is free for non-commercial (home and academic) use. PrimoPDF: Proprietary: Yes: Virtual printer, for Microsoft .NET Framework and uses Ghostscript and RedMon.
Free-form deformation. In computer graphics, free-form deformation (FFD) is a geometric technique used to model simple deformations of rigid objects. It is based on the idea of enclosing an object within a cube or another hull object, and transforming the object within the hull as the hull is deformed. Deformation of the hull is based on the ...
