The agent can operate in a distributed and asynchronous fashion. We investigate new problems that arise out of the interaction between observations and control actions by the agent. We show that new non-classical and non-commutative probability models are needed in order to properly formulate such problems. The models we develop here are inspired by models developed for dynamical physics problems. We establish a series of fundamental results for the trade-off between information and control patterns in distributed stochastic control, detection and estimation.","PeriodicalId":438483,"journal":{"name":"2003 IEEE International Workshop on Workload Characterization (IEEE Cat.

These large emittances must be reduced or \"cooled\" both in size and in energy spread before the muons can be efficiently accelerated. Therefore, formation of muon beams sufficiently intense to drive a Neutrino Factory or Muon Collider requires multi-stage preparation. Further, because of the large beam phase space which must be successfully controlled, accelerated, and transported, the major stages that comprise such a facility: proton driver, production, capture, phase rotation, cooling, acceleration, and storage are complex and strongly interlinked. Each of the stages must be consecutively matched and simultaneously optimized with upstream and downstream systems, meeting challenges not only technically in the optics and component design, but also in the modeling of both new and extended components. One design for transverse cooling, for example, employs meter-diameter solenoids to maintain strong focusing - 300-500 mr beam divergences - across ultra-large momentum ranges, /spl ges/ /spl plusmn/20% /spl delta/p/p, defying conventional approximations to the dynamics and field representation. To now, the interplay of the different systems and staging strategies has not been formally addressed. This work discusses two basic, but different approaches to a Neutrino Factory and how the staging strategy depends on beam parameters and method of acceleration.","PeriodicalId":438483,"journal":{"name":"2003 IEEE International Workshop on Workload Characterization (IEEE Cat.

Ideal turbulence is observed in various idealized models of real distributed systems, addressed by electrodynamics, acoustics, radiophysics, etc. Unlike real systems, in ideal systems (without internal resistance), cascade processes are capable of giving birth to structures of arbitrarily small scale and even causing stochastization of the systems. Just these phenomena are readily described in the contest of ideal turbulence, and allows to understand the mathematical scenarios for many features of real turbulence. A mathematically rigorous definition of ideal turbulence is based on standard notions of dynamical systems theory and chaos theory.","PeriodicalId":438483,"journal":{"name":"2003 IEEE International Workshop on Workload Characterization (IEEE Cat.

In modeling nonholonomic control systems, we especially focus on vakonomic mechanics, which is one of the constrained variation methods to derive the equations of motions of constrained systems. Using vakonomic mechanics, we introduce the vakonomic affine system (VAS) and analyze it theoretically in the context of nonlinear control theory.
