Topic: Coherent space


  
  Coherent sheaf - Wikipedia, the free encyclopedia
In mathematics, especially in algebraic geometry and the theory of complex manifolds, a coherent sheaf F on a locally ringed space X is a sheaf isomorphic with the cokernel of a morphism of O
The role played by coherent sheaves is as a class of sheaves, say on an algebraic variety or complex manifold, that is more general than the locally free sheaf — such as invertible sheaf, or sheaf of sections of a (holomorphic) vector bundle — but still with manageable properties.
In the basic work of Serre, it was shown first that compact complex manifolds have the property that their sheaf cohomology for any coherent sheaf consists of vector spaces of finite dimension.

 ESA Portal - First ever 'Space Council' paves the way for a European space programme
Space is an area where the added value of a joint and coherent policy on the European level is very clear.
The European space programme, to be defined in concept by the end of 2005, will constitute a common, inclusive and flexible platform encompassing all activities and measures to be undertaken by the EC, ESA and other stakeholders (e.g.
To this end, a second "Space Council" meeting is planned for Spring 2005 to define general governance principles, identify priorities as well as the roles and responsibilities of all stakeholders and establish industrial policy principles.

 Why U.S.A. has need of a coherent space policy
The author's zeal to locate space policy thus is valid, and a service to those who fall into the "read one book" category, as well as to the residents of Washington, D.C.'s relevant stovepipes: engineers, technocrats, military officers.
Space is America's "Second Manifest Destiny." We're both a space power and a space-faring people.
Lambakis may be exaggerating when he claims: "The national vision for space will decide everything else." But perhaps not by all that much.

 NATURE OF ORDER EXCERPT
It is this living space, endowed with the properties, endowed therefore with living centers, that forms the effective and useful hull of urban space, to support society.
When we looked at the space of the project as a whole, and the overall three-dimensional pattern of this space, we could see that the system of secondary narrow streets connecting the courtyards, and functioning as a backup system to the main spaces of the larger streets, enormously increased the life of the thing.
It is the whole of this structure of space, all the space that is shown fl and solid in this diagram, which forms the hull that is to be built.

 Yorkshire CND - Dealing with the Inevitable Conflict in Space - 4/1/01
Space has long been militarized, but in order to keep it from being weaponized, other nations would have to give up some of their own potential to use space for military purposes.
Space superiority plans should consist of the appropriate application of non-lethal and lethal force applied in the appropriate medium to ensure the availability of space for U.S. and allied forces and the denial of the use of space for enemy forces.
Orbiting space systems have the potential to impact an enormous portion of the globe, and therefore, space superiority must be evaluated from the perspective of all of space, not just a limited theater of operations.

The interior planes of the space are deliberately kept at an abstract, homogeneous level, with white marble flooring, uniform white panelled ceilings, sloping, white concrete columns and large areas of glass towards the south and west.
The roof surface is interpreted as a large block of ice or glacier and the space immediately under this as a slow, almost glacial movement that changes according to the way in which the “sheet of ice” moves towards the waterfront.
Eliasson’s proposal is inspired by the quality and character of the spaces, crevices and tunnels one finds under glaciers and ice floes – the life under, and inside the ice before it collapses dramatically, suspended in another, slower time sequence where only minor, sudden movements and vibrations are detectable.

 Outer Space and the Multilateral Treaty-Making Process
From the beginning of the space age, deliberate efforts to create a coherent body of law for outer space and space activities were undertaken at the United Nations.
The development of space military capabilities requires an adequate normative response from the international community, which is concerned with the escalation of an arms race in outer space.
Space law-making is no longer restricted to the UNCOPUOS, although this remains the principal UN body concerned exclusively with legal questions arising from the exploration and use of outer space.

 The SPAce Readiness Coherent Lidar Experiment (SPARCLE) Space Shuttle Mission   (Site not responding. Last check: 2007-09-10)
The detector output signal occurs at the difference frequency between the backscattered photons and the LO photons, which is arranged to be in the radio frequency (RF) range for the benefit of the receiver components that follow the detector.
The measurement of vector winds from space with a laser involves complex interactions of the lidar instrument, the space platform, the atmosphere, and the earth.
The atmosphere contributes to lowered SNR through laser beam extinction on the transmit and receive paths, spatial coherence length reduction of the reflected light due to the random locations and spatial extent of the illuminated aerosol particles, and spatial coherence length reduction of the reflected light due to refractive turbulence.

 The Biology of Free Will
The coherent organism is, in the ideal, a quantum superposition of activities - organized according to their characteristic space-times - each itself coherent, so that it can couple coherently to the rest (Ho, 1995b; 1996a).
I venture to suggest, therefore, that a truly free individual is a coherent being that lives life fully and spontaneously, without fragmentation or hesitation, who is at peace with herself and at ease with the universe as she participates in creating, from moment to moment, its possible futures.
The coherent pure state (which is factorizable) is the prerequisite for instantaneous, lossless intercommunication, because the slightest change will give rise to a 'signal' passing between the uncorrelated factorizable parts.

 What is (Schrödinger's)Negentropy?
Enzyme catalysis depends on the very rapid `fluctuations' as the protein samples its `conformational space' in the context of its micro-environment, so that the single trajectory corresponding to efficient enzyme action can be readily accessed in a coherent, or highly cooperative way over the whole of the macromolecule.
One of the predictions of Fröhlich's hypothesis of coherent excitations is extreme sensitivity to weak electromagnetic fields, which can precipitate specific coherently excited states or interfere with their formation at phase transition.
Coherence in a space-time structured system is a transparency of energy and information transfer throughout the entire system.

 Griffin Remarks To The National Space Club
Space exploration is the most technically challenging endeavor that nations do, and it is also one of the most exciting and inspirational.
It is now up to us in the space community to implement the charge we've been given, but, finally, we have the policy we have needed and wanted for almost two generations.
American progress in space since Apollo has not been what many of us here would have wished, precisely because we lacked a coherent national space policy, but as all of us in Washington know, budgets are just as important.

 ARMY STICKS WITH EXISTING MASTER PLAN TO DEFEND SPACE-BASED ASSETS
DOD is drafting an overall space control strategy aimed at bolstering the protection of military space assets, including satellites, ground-based systems and associated terminals and receivers.
A February 2001 draft of the space control strategy has already drawn criticism from Army, Navy and Air Force officials because they said it is lacking in details and specific milestones needed to “provide stronger leadership and accountability” for a coherent space program, according to the report.
One military space expert said the current friction between the services and defense-wide strategies probably stems from the fact that the Bush administration has indicated it wants a new approach to space control, yet has not “figured out what that different approach is.

 The Biology of Free Will
And that is what the coherence of the organism entails.
The coherence of the organism is therefore closely tied up with its energetic status, as argued in the beginning of this essay: the coherent whole is full of energy -- it is a vibrant coherent whole.
The coherent organism is, in the ideal, a quantum superposition of activities -- organized according to their characteristic space-times -- each itself coherent, so that it can couple coherently to the rest (

 PRM/NSC-23: A Coherent U.S. Space Policy
SUBJECT: A Coherent U.S. Space Policy (C) I am concerned that the United States does not have a coherent national space policy guiding our civil, military and national intelligence space programs.
I, therefore, direct that the Policy Review Committee thoroughly review existing policy and prior efforts, and formulate a statement of overall national goals in space, the principles which should guide U.S. government and private use of space and related activities, and a clearer definition of the roles and responsibilities of the federal government agencies involved.
The recommended National Space Policy, implementation plan, and disposition of the designated NSAMs, NSDMs, recommendations and requests will be submitted for my review and approval by 1 July 1977.

Traditionally the two scenarios of interest are noncoherent and coherent STC.
In noncoherent STC neither the receiver nor the transmitter knows the channel propagation coefficients, while in coherent STC, only the receiver has knowledge of channel through training.
The basic the problem in STC is to design codes with simple encoding and decoding algorithms.

Video representation schemes are needed to segment a video stream into meaningful video-objects, useful for later indexing and retrieval applications.
In the proposed methodology, unsupervised clustering via Gaussian mixture modeling extracts coherent space-time regions in feature space, and corresponding coherent segments (video-regions) in the video content.
A key feature of the system is the analysis of video input as a single entity as opposed to a sequence of separate frames.
