Geometric Brownian motionA geometric Brownian motion (GBM) (also known as exponential Brownian motion) is a continuous-time stochastic process in which the logarithm of the randomly varying quantity follows a Brownian motion (also called a Wiener process) with drift. It is an important example of stochastic processes satisfying a stochastic differential equation (SDE); in particular, it is used in mathematical finance to model stock prices in the Black–Scholes model.
Polygonal chainIn geometry, a polygonal chain is a connected series of line segments. More formally, a polygonal chain P is a curve specified by a sequence of points called its vertices. The curve itself consists of the line segments connecting the consecutive vertices. A simple polygonal chain is one in which only consecutive segments intersect and only at their endpoints. A closed polygonal chain is one in which the first vertex coincides with the last one, or, alternatively, the first and the last vertices are also connected by a line segment.
Street artStreet art is visual art created in public locations for public visibility. It has been associated with the terms "independent art," "post-graffiti", "neo-graffiti" and guerrilla art. Street art has evolved from the early forms of defiant graffiti into a more commercial form of art, as one of the main differences now lies with the messaging. Street art is often meant to provoke thought rather than rejection among the general audience through making its purpose more evident than that of graffiti.
Interactive filmAn interactive film is a video game or other interactive media that has characteristics of a cinematic film. In the video game industry, the term refers to a movie game, a video game that presents its gameplay in a cinematic, scripted manner, often through the use of full-motion video of either animated or live-action footage. In the film industry, the term "interactive film" refers to interactive cinema, a film where one or more viewers can interact with the film and influence the events that unfold in the film.
