Temperature measurement by thermocouple probe: influences of variable fluid velocity on the dynamic characteristics of thermocouple
"... Abstract. The problem of dynamic thermocouple compensation is considered. Taking into account the nonlinear dependency of the thermocouple time constant on fluid velocity, a thermocouple model and a time constant model are proposed successively for estimation of nonlinear thermocouple time constant. ..."

of the dynamic model, thermocouple input can be reconstructed. In general, thermocouple was model as a first order nonlinear model. Time constant is the undetermined parameter of the model. As the present research，a fixed (mean) time constant [2] is almost always used, although it is variable in fluctuating
C++ CODES OF IMPLICIT LU ALGORITHMS FOR ABSDLL01

"... An auction is the process of buying and selling things by oering them up for bid, taking bids, and then selling the item to the highest bidder. In economic theory an auction is a method for determining the value of a commodity that has an undetermined or variable price. Recently auctions have intere ..."

Fast Computation of Some Asymptotic Functional Inverses
, 1992
"... G. Robin showed that in several naturally occurring asymptotic expansions of the form y(x) ß X n0 Pn (log log x) log n x ; the polynomials Pn satisfy a simple relation P 0 n+1 = aP 0 n + (bn + c)Pn : These results do not give a way to compute these polynomials, since the constant term re ..."

remains undetermined by this equation. In this note, we give a new derivation of some of Robin's results, and show how the constant terms can be computed with only manipulations of onevariable formal power series. From there, all the Pn can be computed efficiently.
Infant injury deaths with unknown intent: what else do we know?
"... Objectives—Strong evidence based on case record reviews indicates that the incidence of child homicide reported from death certificates is under ascertained. The characteristics of infant injury fatalities with undetermined, but suspicious, intent were compared for the probability that they should ..."

be considered homicides. Methods—Using linked birth and death certificates for all birth cohorts in the US from 1983–91, 2345 injury fatalities reported as intentional, 7594 as unintentional, and 431 as undetermined intent were identified. Maternal and infant variables potentially predictive of injury fa
An application of a homotopy analysis method to nonlinear composites IOP PUBLISHING JOURNAL OF PHYSICS A: MATHEMATICAL AND THEORETICAL An application of a homotopy analysis method to nonlinear composites
"... Abstract In this paper, the homotopy analysis method is employed to decompose the classical boundaryvalue problem of nonlinear composite media into an infinite number of linear partial differential equations, solving each linear partial differential equation by separating variables together with t ..."

LorentzCovariant Quantization of Massless NonAbelian Gauge Fields in The Hamiltonian PathIntegral Formalism
, 2000
"... The Lorentzcovariant quantization performed in the Hamiltonian pathintegral formalism for massless nonAbelian gauge fields has been achieved. In this quantization, the Lorentz condition, as a constraint, must be introduced initially and incorporated into the YangMills Lagrangian by the Lagrange ..."

undetermined multiplier method. In this way, it is found that all Lorentz components of a vector potential have thier corresponding conjugate canonical variables. This fact allows us to define Lorentzinvariant poisson brackets and carry out the quantization in a Lorentcovariant manner.
From Einstein’s Hole Argument to Dirac and Bergmann Observables.

"... The individuation of pointevents and the Hamiltonian way of distinguishing gravitational from inertial effects in general relativity are discussed. The fact that both particle physics and all the approaches to gravity make use of variational principles employing singular Lagrangians [1] has the con ..."
Abstract
 Add to MetaCart
the consequence that the EulerLagrange equations cannot be put in normal form, some of them may be non independent equations (due to the contracted Bianchi identities) and a subset of the original configuration variables, the gauge variables, are left completely undetermined. This leads to the necessity of a
Complex singularities and the Lorenz attractor

As a step toward mathematical analysis, we allow the time variable in the three dimensional Lorenz system to ..."
