We will discuss several techniques for obtaining point estimates and confidence intervals for steady-state performance measures. Let (X(t): t≥ 0) be a GSMP with (discrete) state space S that represents the underlying stochastic process of a simulation. Fix a real-valued function f defined on S and set Y(t) = f(X(t)) for t ≥ 0. There are several possible ways to define steady-state performance m...

Dizziness in children can be caused by a variety of peripheral and central vestibular disorders. Although less frequent in children than in adults, these disorders often pose a diagnostic challenge.

The signal formation and properties of steady-state free precession (SSFP) in combination with alternating RF pulse phases or alternating spin precession is analyzed. Simulations and experiments demonstrate that the amplitudes of SSFP echo paths are significantly influenced by application of alternating phases either via the exciting RF pulse or via some external mechanism producing alternating...

This paper contains rigorous results on nonequilibrium steady states for a class of particle systems coupled to unequal heat baths. These stochastic models are derived from the mechanical chains studied by Eckmann and Young by randomizing certain quantities while retaining other features of the model. Our results include the existence and uniqueness of nonequilibrium steady states, their relati...

We propose a thermodynamic formalism that is expected to apply to a large class of nonequilibrium steady states including a heat conducting fluid, a sheared fluid, and an electrically conducting fluid. We call our theory steady state thermodynamics (SST) after Oono and Paniconi’s original proposal. The construction of SST is based on a careful examination of how the basic notions in thermodynam...

We present a survey of certain aspects of the theory of steady water waves with emphasis on the role played by vorticity. Historical background, numerical illustrations, and brief discussions of the time-dependent problem and of approximate models are included as well.

This paper provides a briefdescription ofthe rationale behind steady-state modelling, and ofthe implementation ofthe ECOPATH II software system, a system for straightforward construction, parametrization, and balancing of steady-state trophic models of(aquatic) ecosystems. ECOPATH II is written for MS DOS computers and is available as a public domain software from the ICLARM Software Project. E...

A major upgrade of the Tore Supra heat and particle exhaust capability, known as the CIEL project [P. Garin et al.,this conference] and installed during the year 2000 shutdown, will raise the heat exhaust capability to 25 MW (convected + radiated) steady-state, and the pumping capability to -4 Fa.m3/s, and will allow Tore Supra to investigate high power steady-state plasma operation, with targe...

Modern cosmology began with the realization that there were solutions to Einstein’s theory of gravity discovered by Friedmann and Lemaitre which when combined with the redshift distance relation of Hubble and others could be interpreted as showing that we live in an expanding universe. It was then only elementary logic to argue that if time reversal was applied, the universe must originally hav...

An affine motion is a continuous map from time value t to an affinity At. It is a SAM (Steady Affine Motion), when At = A . Although the beauty of a motion is subjective, the above equation provides one mathematical characterization and includes the screw (“universal instantaneous”) motion and the golden (“mirabilis”) spiral. Although a real matrix, A, may not exist, we show that it does for a ...
