Facets of an Assignment Problem with 0–1 Side Constraint
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-09)
We show that the problem of finding a perfect matching satisfying a single equality constraint with a 0–1 coefficients in an n × n incomplete bipartite graph, polynomially reduces to a special case of the same peoblem ...
A staggered-mesh finite-difference numerical method for solving the transport equations in low pressure rf glow discharges
(Elsevier, 1988-07)
A numerical model of a low pressure parallel plate rf glow discharge is presented based on a self-consistent formulation of the energy-momentum conservation equations for electrons, the continuity equations for both electrons ...
Differential operators commuting with invariant functions
(Birkhäuser Verlag; Birkhäuser Verlag, Basel, ; Springer Science+Business Media, 1997-10)
Let be a reductive, complex Lie algebra, with adjoint group G , let G act on the ring of differential operators via the adjoint action and write for the differential of this action. We prove that the commutant, in , of is ...
Immanants of Totally Positive Matrices are Nonnegative
(Oxford University PressWiley Periodicals, Inc., 1991-09)
Efficient Bayesian hierarchical functional data analysis with basis function approximations using Gaussian–Wishart processes
(Wiley Periodicals, Inc.Springer US, 2017-12)
Ultraviolet stability of three-dimensional lattice pure gauge field theories
(Springer-Verlag, 1985-06)
We prove the ultraviolet stability for three-dimensional lattice gauge field theories. We consider only the Wilson lattice approximation for pure Yang-Mills field theories. The proof is based on results of the previous ...
Measurement of temperature, fuel concentration and equivalence ratio fields using tracer LIF in IC engine combustion
(Springer-Verlag, 2000-11)
A technique based on planar laser-induced fluorescence of 3-pentanone, for measurements of absolute concentration, temperature and fuel/air equivalence ratios in turbulent, high-pressure combustion systems such as an ...
Ion acoustic parametric decay instability in a plasma with [beta] > 1
(Elsevier, 1976-10-04)
It is found that in a plasma with [beta] > 1 a finite amplitude ion acoustic wave is unstable and decays into two shear Alfven waves propagating in opposite directions. The threshold and growth rate of the instability ...
Parametric and Semiparametric Model-Based Estimates of the Finite Population Mean for Two-Stage Cluster Samples with Item Nonresponse
(Blackwell Publishing Inc, 2007-12)
This article concerns item nonresponse adjustment for two-stage cluster samples. Specifically, we focus on two types of nonignorable nonresponse: nonresponse depending on covariates and underlying cluster characteristics, ...
