Models as people artist model — in art school modeling, a person who poses for purposes of art . model — person whose occupation is to display clothing (eg. a "fashion model") or other personal items of artistic or aesthetic value, and who is often physically attractive; a model who attains celebrity status or is otherwise widely known is said to be a "supermodel". promotion model— promotes a product or service role model — person who acts as a behavioural or moral example to others. Models as physical objects physical model — physical representation of an object; in engineering, similitude is used in the scientific testing of physical models. scale model — a replica or prototype of an object built as a hobby or for research. 01a 3d Driver Model Mouse Net a particular version of a series of vehicles produced by an automobile manufacturer is known as a model. Model-View-Controller (MVC) is a software architecture that separates an application's data model, user interface, and control logic into three distinct components so that modifications to one component can be made with minimal impact to the others.

" Furthermore, the Standard Model provides no mechanism to generate the cosmic inflation that is believed to have occurred at the beginning of the universe, a consequence of its omission of gravity. The Higgs boson, which is predicted by the Standard Model, has not been observed as of 2005 (though some phenomena were observed in the last days of the LEP collider that could be related to the Higgs; one of the reasons to build the LHC is that the increase in energy is expected to make the Higgs observable). The first experimental deviation from the Standard Model came in 1998, when Super-Kamiokande published results indicating neutrino oscillation. This implied the existence of non-zero neutrino masses since massless particles travel at the speed of light and so do not experience the passage of time. The Standard Model did not accommodate massive neutrinos, because it assumed the existence of only "left-handed" neutrinos, which have spin aligned counter-clockwise to their axis of motion. If neutrinos have non-zero mass, they necessarily travel slower than the speed of light. Therefore, it would be possible to "overtake" a neutrino, choosing a reference frame in which its direction of motion is reversed without affecting its spin (making it right-handed). 3d Cad Model Since then, physicists have revised the Standard Model to allow neutrinos to have mass, which make up additional free parameters beyond the initial 19. A further extension of the Standard Model can be found in the theory of supersymmetry, which proposes a massive supersymmetric "partner" for every particle in the conventional Standard Model. "
