	Oval (geometry) - Wikipedia, the free encyclopedia
		In geometry, an oval or ovoid (from Latin ovum, 'egg') is any curve resembling an egg or an ellipse.
		Unlike other curves, the term 'oval' is not well-defined and many distinct curves are commonly called ovals.
		In the theory of projective planes, oval is used to mean a set of q + 1 non-collinear points in PG(2,q), the projective plane over the finite field with q elements.

	GEOMETRY - LoveToKnow Article on GEOMETRY
		Pythagoras (q.v.), seeking the key of the universe in arithmetic and geometry, investigated logically the principles underlying the, known propositions; and this resulted in the formulation of definitions, axioms and postulates which, in addition to founding a science of geometry, permitted a crystallization, fractional, it is true, of the amorphous collection of material at hand.
		Pythagorean geometry was essentially a geometry of areas and solids; its goal was the regular solids the tetrahedron, cube, octahedron, dodecahedron and icosahedronwhich symbolized the five elements of Greek cosmology.
		The geometry of the circle,, previously studied in Egypt and much more seriously by Tbales, was somewhat neglected, although this curve was regarded as the most perfect of all plane figures and the sphere the most perfect of all solids.

	OVAL - LoveToKnow Article on OVAL
		The simplest oval is the ellipse; more complicated forms are represented in the notation of analytical geometry by equations of the 4th, 6th, 8th degrees.
		The Cartesian ovals presented themselves in an investigation of the section of a surface which would refract rays proceeding from a point in a medium of one refractive index into a point in a medium of a different refractive index.
		The curve is obviously symmetrical about the line joining the foci, and has the important property that the normal at any point divides the angle between the radii into segments whose sines are in the ratio l: m.

	Geometry Seminar Lecture 2
		A projective geometry is a geometric structure consisting of various types of objects (points, lines, planes, etc.) and the relations between them which satisfies a set of axioms.
		It is easily seen from this construction that the points of the geometry have a natural relation to coordinates, namely we can take as coordinates of a point any non-zero vector written as an (n+1)-tuple in the rank 1 subspace corresponding to that point.
		Oval cones are quadratic sets, but they are degenerate since the tangent space at the vertex is the full space.

	GEOMETRY OF THE PARABOLA
		This has occurred with the parabolic and pointed arches, whose geometry is present in the section of a body existing in the nature that has a system of great stability due to the harmony between its parts.
		Known since a very remote antiquity, in the plane geometry Vitruvio proposed that "so that a space divided into unequal parts results pleasant and aesthetic, the relation between the smallest and the largest part must be the same as between the largest and the whole".
		GEOMETRY OF THE PARABOLA ACCORDING TO All parabolas are similar: while the size varies, the constants of their configuration are the same for all them.

	Track Geometry
		Some basic understanding of the track geometry is essential if you want to build large layouts that join together properly.
		This fact is demonstrated in Oval with Passing Loop, each point offsets the outer track by one straight so there are two straights inserted in the semicircular siding.
		To make the geometry work you need to use the curves supplied with points to bring the middle of the crossover parallel to the main tracks.

	IPNews - Geometry Software Measures Piston Ovality and Skirt Profile (Site not responding. Last check: 2007-11-05)
		Circular geometry gages are typically used to measure the accuracy of cylindrical part features that are specified to be round and straight, so results are normally presented as deviation from perfect roundness or straightness.
		This manufacturer has developed proprietary piston geometries as a competitive advantage, and relies upon the Formscan 3600 geometry gage with Optional Piston Software to confirm the geometry of forgings it receives from a supplier, and to check the features it machines-in-house.
		One racing team that has snared several top-3 finishes on the NASCAR/Winston Cup circuit this year is using a Formscan gage to double-check the geometry of pistons it receives from its supplier, and to experiment in developing its own geometries.

	6moons.com - audio reviews: Analysis Plus Oval 8 and Solo Crystal cables
		I've always wondered whether my preference for the Oval 9 speaker cable vis-à-vis the interconnect was due to the silver-plated copper of the latter.
		A single-wire pair of Oval 9 in residence would serve as the peaches-to-peaches comparator with the newly hatched.
		The hollow oval bass merely lays out a rock-solid foundation that vivifies soundstage realism and sweetens treble by balancing HF extension with the equivalent reach in the other direction.

	Odin: Cartesian Oval Lens Geometry
		A lens with a surface of revolution based on a Cartesian Oval will transform a beam of some phase radius into a beam of another, finite, phase radius.
		The second surface of the lens is spherical and matches the phase radius of the beam at that distance.
		Knowing the quasioptical parameters of the beam, and the mechanical constraints, it is then a simple matter to generate a mechanical drawing for manufacture of the lens.

		The Professional Oval Stage Guitar Cable from Analysis Plus gets its superior sound from the company's critically acclaimed hollow oval conductor geometry, which controls current density for a purer, more uniform musical signal.
		After many computer simulations, Analysis Plus found that a hollow oval cable was the best design due to its minimal change in resistance with frequency, plus other benefits.
		The company chose a flexible, braided conductor rather than the conventional solid conductor, which is susceptible to kinks and deformations with resulting signal degradation.

	Articles: Fitting Failures
		PVC fittings, because of their geometry and material characteristics, are uniquely unqualified to withstand the water hammer and cyclic pressure surges present in these systems.
		In tees, the stress at the corner is further increased because of the unsupported area defined by the overlap of the two cylinders when viewed in the horizontal plane.
		As PVC fittings are pressurized, the fitting deflects internally, attempting to “round up” the oval geometry of the unsupported intersection area.

	GoodSound! "Equipment" Archives
		Among other things, Analysis Plus believes that the geometry of a cable is critical to the cable’s ability to transmit a signal without degradation.
		According to the company’s president, Mark Markel, "every wire is statistically as close to the return current as every other wire." This is said to distribute the current density more evenly, which makes the resistance of the cable constant over a wider range of frequencies compared to conventional round cables.
		The Clear Oval cables that I received were terminated with gold-plated spade lugs that should fit most binding posts.

	SoundStage! Equipment Review - Analysis Plus Oval Nine Speaker Cable and Silver Oval-In Interconnects (6/2000)
		By using a flat oval shape, the inductance of a cable may be lowered, which in this case allowed Analysis Plus to minimize the impedance mismatch between the amplifier and speakers.
		My bi-wire set of Oval Nine speaker cables were a joy to connect to both my amplifier and speakers, as the spades fit snugly around the different binding posts and required a minimal amount of tightening.
		The Oval Nine cables are rather neutral-looking in appearance, with the braided copper wire visible on one side and a mauvish color on the other side of the shield.

		That was their Oval Nines cable, if you remember, that went on to become an instant success and place Analysis Plus on the audiophile map.
		That said, her presence via the Golden Ovals, seemed to emit from right before the microphone a step backwards yet palpably vivid while remaining right-sized and centered between the loudspeakers.
		How the Golden Oval managed to bring so much of what sounds “live” to light, while remaining distant, delicate and “there” simultaneously, is a magical feat I’ve still not quite figured out or have seen this side of Siegfried and Roy (minus the unfortunate tiger attack).

		Many racers are becoming aware of Ackerman Steering geometry and are concerned with how it influences their race cars.
		Most short tracks (oval tracks) have a corner radius of 150'+/-.
		Alignment shops and some Dealerships will refer to Ackerman as "toe-out." This is because Ackerman steering geometry causes the wheels to toe-out during a sharp turn.

	SoundStage! Equipment Review - Analysis Plus Solo Crystal Oval Interconnects and Solo Crystal Oval 8 Speaker Cables ...
		Continuous Cast Copper wire and patented hollow oval geometry produce a cable that Analysis Plus claims is measurably better than the competition.
		With the Solo Crystal Oval cables in my system, treble takes on more of a metallic or silky tinge depending on the recording, displaying seemingly greater extension in the process, while bass has more pit-of-the-stomach power.
		Cables that are described as neutral and transparent, words that fit the Solo Crystal Oval cables well, often sound lean and even slightly devoid of harmonic color, but the Analysis Plus cables are palpable and fleshy through the midrange, the antithesis of thin or bleached.

		The Solo Crystal Oval cables add another interesting twist -- oxygen-free copper wire that's slowly drawn and annealed so that its grain boundaries are non-existent in normal audio lengths.
		Analysis Plus calls this Continuous Cast Copper; similar wire is used by Harmonic Technology and Acoustic Zen, albeit without the hollow oval geometry.
		Of all the cables I've heard recently, the ones the Analysis Plus Solo Crystal Oval cables resemble the most sonically are Nordost's Quattro-Fil interconnects and SPM Reference speaker cables.

		The quite expensive (at $630 a meter), Silver Oval-in Interconnects are also built from pure silver layered over a stabilizing strand of oxygen-free copper braided into their patented hollow oval geometry.
		With the AP Oval Silver, the instruments took on a more palpable dimensionality and body, whereas the HT seemed dimensionally truncated, more two-dimensional, but longer in the extension department from top to bottom.
		At $499, a fraction of the cost of most reference-caliber speaker cables, while the quite expensive Silver Oval-in interconnect at $630, is sure going to become a great deal of talk among audiophiles.
