61Ruled surface — A hyperboloid of one sheet is a doubly ruled surface: it can be generated by either of two families of straight lines. In geometry, a surface S is ruled if through every point of S there is a straight line that lies on S. The most familiar… …
62Leading edge cuff — Leading edge cuffs are a fixed aerodynamic device employed on fixed wing aircraft to modify the airfoil used. They may be either factory installed or, more commonly, an after market modification.In most cases a leading edge cuff will “droop” the… …
63Freeform surface modelling — is the art of engineering Freeform Surfaces with a CAD or CAID system. Introduction The technology encompasses two main fields. Either creating aesthetic (Class A surfaces) that also perform a function; for example, car bodies and consumer… …

65Cutting Edge Creations — inflatable structure created by Cutting Edge Creations Cutting Edge Creations (CEC) is an Eagan, Minnesota based inflatables company that sells inflatable structures, including bounce houses, slides, advertising inflatables, movie projection… …
66Ocean surface topography — TOPEX/Poseidon was the first space mission that allowed scientists to map ocean topography with sufficient accuracy to study the large scale current systems of the world s ocean. Although this image was constructed from only 10 days of… …
67History of surface weather analysis — The history of surface weather analysis concerns the timetable of developments related to surface weather analysis. Initially a tool of study for the behavior of storms, surface weather analyses became a work in progress to explain current… …
68cuspidal edge — Regression Re*gres sion (r?*gr?sh ?n), n. [L. regressio: cf. F. r[ e]gression.] The act of passing back or returning; retrogression; retrogradation. Sir T. Browne. [1913 Webster] {Edge of regression} (of a surface) (Geom.), the line along which a …
69Bézier surface — Bézier surfaces are a species of mathematical spline used in computer graphics, computer aided design, and finite element modelling. As with the Bézier curve, a Bézier surface is defined by a set of control points. Similar to interpolation in… …
70Hidden surface determination — In 3D computer graphics, hidden surface determination (also known as hidden surface removal (HSR), occlusion culling (OC) or visible surface determination (VSD)) is the process used to determine which surfaces and parts of surfaces are not… …
