	Curvilinear coordinates - Wikipedia, the free encyclopedia
		Curvilinear coordinates are a coordinate system based on some transformation of the standard coordinate system.
		(r, θ) are the curvilinear coordinates, and the Jacobian determinant of the transformation (r,θ) → (r cos θ, r sin θ) is r.
		Since we use curvilinear coordinates to aid in the calculation in vector calculus, there are adjustments we need to make in the calculation of line, surface and volume integrals.

		In preferred embodiments, the curvilinear transverse cross section is symmetric along the longitudinal centerline of the skateboard body and extends longitudinally along part of, or the entire length of the skateboard body.
		In alternate embodiments of the invention the curvilinear transverse cross section is approximated by a plurality of linear cross section segments.

	Apparatus and method for constructing adjustable curvilinear concrete forms - Patent 4185805
		A form having a selectively adjustable curvilinear surface is provided by securing a flexible connection plate to the rear side of a flexible form panel and clamping the plate to a rigid waler to lock the panel in the desired curvilinear configuration.
		The present invention relates to an adjustable form for forming curvilinear concrete surfaces and is especially concerned with an improved waler which provides for selective adjustment of a flexible form panel to a desired curvilinear shape.
		The present invention is concerned with an apparatus and method wherein a flexible waler construction is employed which accommodates select adjustment of the curvilinear shape of a flexible form panel supported thereby and the locking of the panel in the adjusted curvilinear shape.

	The modern abstract curvilinear paintings of Alton S. Tobey
		The next stage of his curvilinear paintings involved the development of three dimensionsal effects on his working surfaces, created with painted strings, wires, metallic elements and found objects, rendered to appear to be totally metallic.
		Although Tobey intended each piece to be something specific - often reflected in the title of the work - he and the paintings themselves encourage viewers to find their own meaning in each work, and to enjoy it in their own way, rather than holding to his own personal intentions as an artist.
		In his later Curvilinear works, small realistic images emerge in the backgrounds of the paintings, integrating the subjective observers into his own personal relationships with his abstracted figurative and suggestive realities.

	Froebel Gifts Curvilinear Page (Site not responding. Last check: 2007-10-17)
		The use of the Curvilinear Gifts were championed in the United States by Belle Woodson, an instructor at the Chicago Kindergarten College and by Minnie Maud Glidden, a kindergartner and instructor at the Pratt Institute.
		Whether the Curvilinear Series were widely used is not yet clear, but they definitely add a wonderful dimension to block play and all its Froebelian aspects.
		The introduction of the Curvilinear series came long after Frank Lloyd Wright had left the nursery, but he was known to use the Gifts as a scratch pad for designs.

	ED230B/C: Curvilinear Regression
		Contrary to how it sounds, curvilinear regression uses a linear model to fit a curved line to data points.
		Curvilinear regression makes use of various transformations of variables to achieve its fit.
		Curvilinear regression should not be confused with nonlinear regression (NL).

	Curvilinear Component Analysis
		Curvilinear Distance Analysis (CDA in short) is the last development in a well known family of nonlinear projection methods.
		Curvilinear Distance Analysis (CDA) lies one step beyond: the main difference between CCA and CDA is that the latter uses a special kind of distance measurement called Curvilinear Distances.
		In practice, the curvilinear distance is computed as the shortest path between two prototypes of the codebook, after quantization and linking of the prototypes.

	Curvilinear Arrays
		Recently, the sound reinforcement profession has exhibited considerable interest in new implementations of the venerable line array concept, and in these implementations the array is often curved (in some instances quite radically) to accommodate coverage requirements.
		As its name suggests, the M2D is designed specifically for implementing vertical curvilinear arrays of up to 12 cabinets having 0° to 7° splay between adjacent units.
		Figure 4 shows the directional radiation pattern of a curved array (5° splay between cabinets) of six M2Ds at 500 Hz, with three measurement microphone positions designated A, B and C. Figures 5, 6 and 7 show the far field frequency response (one-third octave resolution) at each of these positions.

	The Waveguide Mesh in General Curvilinear Coordinates
		A generalization of the waveguide mesh to arbitrary curvilinear coordinates is useful in that it becomes possible to model boundary conditions which may not be simply aligned with a rectilinear grid.
		The resulting structure is quite similar to the interleaved forms discussed earlier, and for this reason we will give only a brief description of the coordinate transformation procedure.

	Derivation of the Singular Integral Equations for Curvilinear Cracks with Computer Algebra Software -- from Mathematica ...
		The classical Cauchy-type complex singular integral equation for the general curvilinear crack problem in plane isotropic elasticity is rederived by using an appropriate computer procedure, based on the Mathematica computer algebra system.
		Both cases of one crack (or a system of cracks) and of a periodic array of cracks are considered in detail and the Mathematica procedure is displayed.
		The subsequent use of a numerical algorithm for the solution of the derived complex singular integral equation is also possible.

	M2D : Compact Curvilinear Array
		The M2D is designed specifically for vertical curvilinear arrays of up to 16 cabinets having 0- to 7-degree splay between adjacent units.
		Pioneered by Meyer Sound in the early 1980s, horizontal curvilinear arrays composed of trapezoidal cabinets have been an industry standard for decades.
		The M2D extends the concept to vertical arraying, enabling flexibility to tailor vertical coverage by varying the number and splay of cabinets in the array while maintaining a constant 90 degrees of horizontal coverage.

		Of special interest is the HTD timing belt drive which features a deep curvilinear profile for more positive non-slip operation and reduced backlash when compared with the conventional trapezoidal tooth profile.
		This provides greater shear strength and smaller unit pressure per tooth since the area of contact is greater.
