  Method and apparatus for controlling continuously variable transmission for vehicle - Patent 4649488
Then, a desired or target engine speed contemplated by a vehicle driver, corresponding to the operating amount of the accelerator pedal or the opening angle of the throttle valve, is determined based on a relation predetermined so as to provide the required horsepower of the engine with the minimum specific fuel consumption.
Further, since the target engine speed determined according to the instant method is based also on the detected running speed of the vehicle, the target engine speed may be determined such that the speed ratio of the transmission is controlled for maximum transmission efficiency of the transmission at each specific running speed of the vehicle.
The illustrated embodiment of the invention is further advantageous because of the arrangement wherein the target engine speed Ni' is elevated as the vehicle running speed V is increased, i.e., the speed ratio e of the transmission 14 is lowered as the vehicle running speed V is increased.

 Primer for Geometric Regions   (Site not responding. Last check: 2007-10-08)
Manifolds consist of a set of Mapped Regions with the same base space and target space.
Manifolds must provide member functions for determining how many charts are in the atlas, member functions corresponding to the member functions of each chart, and member functions for moving between charts.
A boundary is a lower dimensional Manifold which divides the interior of the Manifold from the exterior (the base space of the boundary is of one dimension less, and the target space is the same).

 Georegistration
During georegistration the target image will be re-projected to match the reference drawing using the control points as a guide.
Manifold will match those control points in the reference component to the target component by name and will re-project the target component so that its control points are in the same locations as the reference component.
Manifold will refuse to use control points that are placed on top of each other in the same image or drawing.

The Borel Conjecture predicts that closed aspherical manifolds are topological rigid.
If f: N ---> M is an orientation preserving homotopy equivalence with a closed oriented manifold as target, then there is an orientation preserving homeomorphism h: N ---> M such that h and f induce up to conjugation the same maps on the fundamental groups.
We also classify manifolds of dimension 5 or 6 whose fundamental group is the one of a surface and whose second homotopy group is trivial.

 Custom Datum Grids for NTv2   (Site not responding. Last check: 2007-10-08)
Datum grids are stored in GSB "grid shift" files and are described using XML files with the same name that contain one or more datum pairs to use with the grid.
The point of providing an XML file like the above is to tell Manifold the names of the datums that are to be converted with NTv2 using this grid shift file.
Given a pair of source and target datums, Manifold will use the custom grid file to convert coordinates both from the source datum to the target datum and from the target datum to the source datum.

Abstract: The Poisson sigma model is a bidimensional field theory having as target manifold a Poisson manifold.
Kontsevich formula for the deformation quantization of the target manifold is interpretable as the perturbative expansion of a particular correlator of the model.
In this seminar, we clarify the meaning of the inegrality condition of the Poisson tensor which appears both in the integration of the gauge transformations of the model and in the geometric quantization of the target manifold.

Throttle: On the Baron, the throttle controls manifold pressure, which is displayed in inches of mercury on the manifold pressure gauges.
You can increase or decrease the manifold pressure with the throttle control on a joystick or yoke, by dragging the throttle with a mouse, or by pressing F3 to increase power and F2 to decrease power.
By "minor," we mean increments of one inch of manifold pressure (with the throttle) and one or two degrees of pitch (with the joystick or yoke).

We present the notion of isocausality between Lorentzian manifolds, a new concept which generalizes and improves the well known idea of conformal relationship.
This is accomplished by means of the definition of causal relations between Lorentzian manifolds which are diffeomorphisms mapping causal future-directed vectors of a domain manifold onto causal future-directed vectors of a target manifold.
If two reciprocal such mappings exist---from the domain manifold to the target one and vice versa--- both manifolds are said to be isocausal as they share a number of global causal properties.

A Mapped Region is a Region which is mapped into a target space (which may have the same dimension as the region).
To implement a Manifold you must provide member functions which: return the dimension of the base space (where the region lives), the target space, the target space itself, and the number of charts.
A Manifold may have a boundary, and may be differentiable and/or discrete.

Since a gerbe is a stack, we may look at sigma models with that gerbe as target.

 Sets to Quarks - HyperDiamond Feynman Checkerboard
The volume of the link to the target vertex is not measured just by the number of gauge bosons, but by the volume of the minimal manifold Qforce that can carry two things: the gauge bosons, with gauge group Gforce; and the U(1) phase of the propagator from origin to target.
Since the target Internal Symmetry Space MISforce has fundamentally a 4-dimensional HyperDiamond structure, each irreducible component is fundamentally made up of mforce-dimensional hypercubic cells, where the irreducible component hypercubic cells are 4-dimensional for Gravity and the Color force, 2-dimensional for the Weak force, and 1-dimensional for Electromagnetism.
The link manifold to the target vertex is QC = S^5 = ShilovBdy(B^6) with volume 4pi^3 The bounded complex homogeneous domain DC is of type B^6 (ball) with volume pi^3/6 For the SU(3) Color force, mC is 4.

 Non-linear sigma model - Wikipedia, the free encyclopedia
In quantum field theory, a nonlinear σ model describes a scalar field Σ which takes on values in a nonlinear manifold called the target manifold T. The target manifold is equipped with a Riemannian metric g.
New physics is needed at around the distance scale where the two point connected correlation function is of the same order as the curvature of the target manifold.
A nonlinear σ model with G/H as the target manifold with a G-invariant Riemannian metric and a zero potential is called a quotient space (or coset space) nonlinear σ model.

 Citebase - World-manifold and target space anomalies in heterotic Green-Schwarz strings and five-branes
The quantum consistency of sigma-models describing the dynamics of extended objects in a curved background requires the cancellation of their world-volume anomalies, which are conformal anomalies for the heterotic string and SO(1,5) Lorentz-anomalies for the heterotic five-brane, and of their ten dimensional target space anomalies.
In determining these anomalies in a D=10 Lorentz-covariant back-ground gauge we find that for the heterotic string the worldvolume anomalies cancel for 32 heterotic fermions while for the conjectured heterotic five-brane they cancel for only 16 heterotic fermions, this result being in contrast with the string/five-brane duality conjecture.
For what concerns the target space anomalies we find that the five-brane eight-form Lorentz-anomaly polynomial differs by a factor of 1/2 from what is expected on the basis of duality.

 P.P. Cook's Tangent Space: Vafa describes Topological String Theory
In string theory we map, X, from a Riemann surface into a 10-dimensional manifold, M^10 which is the product of a Minkowski spacetime R^4 which we concede exists and a missing 6-dimensional manifold M^6, which many are less sure of.
The ante was then upped a little as we moved from an S^1 target space to a CY 1-fold (=T^2, the 2-dimensional torus).
For example, Vafa next considered the A-model and its Kahler manifold and gave an argument that the study of TST naturally leads one to be interested in CY 3-folds, without detailed knowledge of string theory.

We discuss the framework for arbitrary target manifolds, while the domain manifold problem was addressed in [3].
The key idea is to implicitly represent the target manifold as the level-set of a higher dimensional function, and then implement the equations in the Cartesian coordinate system of this new embedding function.
Examples of the applications of the framework here described include harmonic maps in liquid crystals, where the target manifold is an hypersphere; probability maps, where the target manifold is an hyperplane; chroma enhancement; texture mapping; and general geometric mapping between high dimensional surfaces.

Shortly, the GW-theory deals with spaces of pseudo-holomorphic curves in symplectic manifolds, that is with spaces of maps with source a Riemann surface and the target a symplectic manifold.
In the HGW-theory the picture is similar, with the change that instead of considering maps whose sources are curves, one is interested in equivariant maps defined on the total space of principal bundles over Riemann surfaces with target a symplectic manifold, and which satisfy the so-called vortex equations.
When the target manifold is a complex projective variety, the connection between the gauge theoretical setup of the HGW-theory and the algebraic-geometric one is achieved through a Kobayashi-Hitchin type correspondence.

They're not a physical target space and we are not supposed to probe all of it.
The place where Nathan's ghosts together with the other degrees of freedom are equivalent to the older formulations of the superstring is a generic point away from the tip of the cone.
The ghosts may give you some determinants or measure from their zero modes, but all of these things are small deviations from a point in the ghost target manifold - and in Nathan's case, this point around which we expand is simply not the tip of the cone.
