  Holonomic - Wikipedia, the free encyclopedia
In robotics holonomicity refers to the relationship between the controllable and total degrees of freedom of a given robot (or part thereof).

 Nonholonomic system - Wikipedia, the free encyclopedia
In physics and mathematics, a nonholonomic system is a system in which a return to the original internal configuration does not guarantee return to the original system position.
In other words, unlike with a holonomic system, the outcome of a nonholonomic system is path -dependent, and the number of generalized coordinates required to represent a system completely is more than its control degrees of freedom(sometimes called differential degrees of freedom, DDOF).
In addition to the motion variables corresponding to the control degrees of freedom,the history of its motion too should be known.

 Comparison between Karl Pribram's "Holographic Brain Theory" and ore conventional models of neuronal ...
The holonomic theory is based on evidence that the main computational event of neurons is the polarizations and hyper polarizations at the dendritic membranes of neurons.
The holonomic theory (for the example of vision) summarizes evidence that the image formed on the retina is transformed to a holographic (or spectral) domain.
Possibly the most radical part of the holonomic theory is Pribram's claim that a "receiver" is not necessary to "view" the result of the transformation (from spectral holographic to "image").

 A Novel Concept   (Site not responding. Last check: 2007-10-22)
Holographic or holonomic image events that exhibit periodic movement in space through time are created as, and reconstructed from higher order energetic holograms that include the dimension of time.
Moreover, individual nonmaterial holonomic minds independently exist on the nonmaterial scale of existence and communicate with the organic human brain through interactive subquantum energy bridge interfaces which link the material and nonmaterial primordial energy domains of physical reality.
In an energetic, multi-level holonomic hierarchy each reciprocally reconstructed (inverted) holonomic scene or venue is produced from a parent hologram generated or stored on the preceding transcendent level of holonomic activity.

 Fundamental Forces   (Site not responding. Last check: 2007-10-22)
From subnuclear elementary particles with electric charge to the cosmos itself, electromagnetism is ubiquitous and limited only by the phenomenal boundary of our reciprocally emergent,6 subluminal holonomic universe.
Particulate matter is organized and maintained as the material feature of our reconstructed, conditionally relative holonomic universe which is created by the energetic activity of the nonmaterial continuum or spectrum of phenomenal consciousness on a reciprocally emergent transcendent level within the fundamental, irreducible, nonmaterial energy domain.
Furthermore, gravity is a property of physical mass and transcendent, reciprocally emergent consciousness is the agent of nonmaterial physical energy.

 Chief Delphi - Holonomic Drive Question   (Site not responding. Last check: 2007-10-22)
The cambered holonomic drive system that Team 116 developed this year used four drive wheels that were located at different radial positions and different distances from the CG.
While a holonomic drive system will be more pushable than a traditional 4-solid wheel system, it is still harder to push than a robot using all onmi-wheels.
In general, a four wheel holonomic drive system will have the equivalent of two wheels that roll freely and two wheels that are resisting the motion.

 Overview of the holonomic paradigm
The development of holonomic brain theory by psychologist Karl Pribram similarly indicates that consciousness is primarily assocaited with nonlocal activity among dendritic microprocesses rather than the biochemical events associated with neural firing.
Although there are still many other areas of research that can be described regarding the holonomic paradigm, the related work of these researchers is sufficient to provide an outline of the new world view implied by the holonomic paradigm.
Much as Copernicus taught us that the earth is not the center of the world, the holonomic paradigm indicates that the world manifest to our senses and our instruments is not the whole world but only a corner of a vast reality beyond what has been imagined.

 Holonomic Elastoplastic Reliability Analysis of Truss Systems. I: Theory   (Site not responding. Last check: 2007-10-22)
Because elastoplastic behavior is a very real possibility under the hazard of random actions during the lifetime of a structural system, it is natural that methods of reliability theory have to be used for the assessment of this type of behavior.
The present paper is the first part of an investigation on holonomic elastoplastic reliability analysis of truss systems under random loads.
Following a brief description of the deterministic direct holonomic elastoplastic analysis formulation, a modified formulation is proposed for the purpose of reliability analysis.

 Halfbakery: Holonomic Cars
One downside is that I don't imagine holonomic wheels would be very good at highway speeds-- but I could be wrong.
If that's the case, then holonomic cars could be city drivers (and as such, be electric) while you use your old non-holo car for long distance treks.
Perhaps someone could develop holonomic hybrids that alter their configuration (perhaps with a dropdown fourth wheel) for higher speeds.

 Holonomic Functions in Computer Algebra (abstract)   (Site not responding. Last check: 2007-10-22)
First, a theoretical framework is introduced in order to give algorithms for the closure properties of the holonomic class, to permit a zero test in this class, and to unify differential calculations with functions and calculations of recurrences with sequences.
These methods are based on calculations by an extension of the theory of Gröbner bases in a framework of non-commutative polynomials, namely Ore polynomials.
Much more than the search for closed forms, the aim is to be able to continue to compute with the implicit representation of holonomic objects even when no explicit form is available.

 Citebase - Holonomic and Legendrian parametrizations of knots
Our main result is that any two holonomic knots which represent the same knot type are isotopic in the space of holonomic knots.
A second result emerges through the techniques used to prove the main result: strong and unexpected connections between the topology of knots and the algebraic solution to the conjugacy problem in the braid groups, via the work of Garside.
We also discuss related parametrizations of Legendrian knots, and uncover connections between the concepts of holonomic and Legendrian parametrizations of knots.

 physics
The Palm Pilot Robot can move holonomically across flat surfaces, which in this case means it may move in any direction while simultaneously controlling rotational speed.
This is true because the omni-wheels have rollers that allow them to freely roll sideways but control the motion in the direction the wheel is pointing.
At each wheel, the velocity depends on v and w, and is the sum of the velocity due to rotation (expressed in the body frame) and the motion of the body frame in the world:

A theorem from control theory relating the Lie algebra generated by vector fields on a manifold to the controllability of the dynamical system is shown to apply to holonomic quantum computation.
Conditions for deriving the holonomy algebra are presented by taking covariant derivatives of the curvature associated with a non-Abelian gauge connection.
In particular, a universal two-qubit logic gate is attainable for this model.

 Consciousness - Wikipedia, the free encyclopedia
Theories that seek to explain phenomenal consciousness directly, such as Space-time theories of consciousness and Electromagnetic theories of consciousness, have been available for almost a century, but have not as yet been confirmed by experiment.
Theories that attempt to explain the QM measurement problem include Pribram and Bohm's Holonomic brain theory, Hameroff and Penrose's Orch-OR theory, Spin-Mediated Consciousness Theory and the Many-minds interpretation.
Some of these QM theories offer descriptions of phenomenal consciousness, as well as QM interpretations of access consciousness.
