Observations of Directional Relaxation of Wind Sea Spectra
Wind Sea Spectra Two-dimensional wave
font style='font-size:12px;'>
2009/2/6
Two-dimensional wave spectra were acquired through a NOAA Experimental Research Buoy in 34 m of water off the North Carolina coast (Atlantic Ocean). These are analyzed in ideal wave-growth situations ...
BV Functions with Respect to a Measure and Relaxation of Metric Integral Functionals
Bounded variation functions Radon measures Relaxation Duality Integral representation
font style='font-size:12px;'>
2009/1/22
We introduce and study the space of bounded variation functions with respect to a Radon measure $\mu$ on $\mathbb{R}^N$ and to a metric integrand $\varphi$ on the tangent bundle to $\mu$. We show that...
Atomic multipole relaxation rates near surfaces
Atomic multipole near surfaces

2010/4/9
The spontaneous relaxation rates for an atom in free space and close to an absorbing surface are calculated to various orders of the electromagnetic multipole expansion. The spontaneous decay rates fo...
On a Non-Standard Convex Regularization and the Relaxation of Unbounded Integral Functionals of the Calculus of Variations

The analysis of the relationships between the functional $F^{(\infty)}(\Omega,\cdot) \colon u \in W^{1,\infty}(\Omega) \mapsto \inf$ $\{\liminf_h \int_\Omega f(\nabla u_h)dx : \{u_h\}$ $\subseteq W^{1...
The Effects on Ocean Models of Relaxation toward Observations at the Surface
Ocean Models Surface
font style='font-size:12px;'>
2008/6/26
This paper discusses the errors in surface tracer and flux fields in ocean models induced by using approximate surface boundary conditions involving relaxation toward observed values rather than more ...
An Analytical Model of Wave Bottom Boundary Layers Incorporating Turbulent Relaxation and Diffusion Effects
Wave Bottom Relaxation Diffusion Effects
font style='font-size:12px;'>
2008/6/16
To calculate the effects of turbulent relaxation on oscillatory turbulent boundary layers, a viscoelastic term is added to an eddy viscosity model. The viscoelastic term parameterizes the lag of turbu...
Electrical Characterization and Relaxation Behavior of Lithium-Indium-Phosphate Glasses via Impedance Spectroscopy
Phosphate glass structure Differential thermal analysis Electrical properties
font style='font-size:12px;'>
2010/4/8
Phosphate glasses with various compositions of lithium oxide and indium oxide were synthesized by melt quenching technique. The glass forming ability parameter Kgl was characterized by differential th...
WAVEFORM RELAXATION METHODS OF NONLINEAR INTEGRAL-DIFFERENTIAL-ALGEBRAIC EQUATIONS
font style='font-size:12px;'>
2007/12/12
In this paper we consider continuous-time and discrete-time waveform relaxation methods for general nonlinear integral-differential-algebraic equations. For the continuous-time case we derive the conv...
ON THE CONVERGENCE OF THE RELAXATION METHODS FOR POSITIVE DEFINITELINEAR SYSTEMS
System of linear equations Relaxation method Convergence theory Positive definite matrix
font style='font-size:12px;'>
2007/12/12
We establish the convergence theories of the symmetric relaxation
methods for the system of linear equations with symmetric positive
definite coefficient matrix, and more generally, those of the
un...
BOX--LINE RELAXATION SCHEMES FOR SOLVING THE STEADY INCOMPRESSIBLENAVIER--STOKES EQUATIONS USING SECOND--ORDER UPWIND DIFFERENCING
font style='font-size:12px;'>
2007/12/11
We extend the SCGS smoothing procedure (Symmetrical Collective
Gauss--Seidel relaxation) proposed by S.~P.~Vanka$^{[4]}$,
for multigrid solvers of the steady viscous incompressible Navier--Stokes

A Relaxation Scheme for Solving the Boltzmann Equation Based on the Chapman-Enskog Expansion
boltzmann equation chapman-Enskog expansion
font style='font-size:12px;'>
2007/12/11
In [16] a visco-elastic relaxation system, called the relaxed Burnett system, was proposed by Jin and Slemrod as a moment approximation to the Boltzmann equation. The relaxed Burnett system is weakly ...
