Adaptive throttle control for speed tracking
(1994)Electronic throttle control is an important part of every advanced vehicle control system. In this paper we design an adaptive control for electronic throttle that achieves good tracking of arbitrary constant speed commands ...

Adaptive virtual circuit routing
(1996)The paper deals with the adaptive routing problem in virtual circuit communication networks. A newly arriving call at a source node is routed along the minimum length path to its destination node. All packets belonging to ...

Aggregation of spectral density estimators
(2014)Given stationary time series data, we study the problem of finding the best linear combination of a set of lag window spectral density estimators with respect to the mean squared risk. We present an aggregation procedure ...

Algebraic aspects of evolution partial differential equations arising in financial mathematics
(2010)In the modelling of various financial instruments, risks, prices of commodities, etc., the end result is frequently an evolution partial differential equation. A remarkable number of these have rich algebraic structures. ...

Algebraic solution of the Stein-Stein model for stochastic volatility
(2011)We provide an algebraic approach to the solution of the Stein-Stein model for stochastic volatility which arises in the determination of the Radon-Nikodym density of the minimal entropy of the martingale measure. We extend ...

An algorithm for robust fitting of autoregressive models
(2009)An algorithm for robust fitting of AR models is given, based on a linear regression idea. The new method appears to outperform the Yule-Walker estimator in a setting of data contaminated with outliers. © 2008 Elsevier B.V. ...

All Abelian Quotient C.I.-Singularities Admit Projective Crepant Resolutions in All Dimensions
(1998)For Gorenstein quotient spaces Cd/G, a direct generalization of the classical McKay correspondence in dimensionsd≥4 would primarily demand the existence of projective, crepant desingularizations. Since this turned out to ...

All toric local complete intersection singularities admit projective crepant resolutions
(2001)It is known that the underlying spaces of all abelian quotient singularities which are embeddable as complete intersections of hypersurfaces in an affine space can be overall resolved by means of projective torus-equivariant ...

The Almansi method of fundamental solutions for solving biharmonic problems
(1988)A new fundamental solutions method for the numerical solution of two‐dimensional biharmonic problems is described. In this method, which is based on the Almansi representation of a biharmonic function in the plane, the ...

Analysis of the singular function boundary integral method for a biharmonic problem with one boundary singularity
(2012)In this article, we analyze the singular function boundary integral method (SFBIM) for a two-dimensional biharmonic problem with one boundary singularity, as a model for the Newtonian stick-slip flow problem. In the SFBIM, ...

Analysis of traffic flow with mixed manual and semiautomated vehicles
(2003)The introduction of semiautomated vehicles designed to operate with manually driven vehicles is a realistic near-term objective. The purpose of this paper is to analyze the effects on traffic-flow characteristics and ...

Analytic regularity for a singularly perturbed system of reaction-diffusion equations with multiple scales
(2013)We consider a coupled system of two singularly perturbed reaction-diffusion equations, with two small parameters 0 < ε ≤ μ ≤ 1, each multiplying the highest derivative in the equations. The presence of these parameters ...

Analytic residues along algebraic cycles
(2005)Let W be a q-dimensional irreducible algebraic subvariety in the affine space A C n, P1,..., Pm m elements in C[X1,...,Xn], and V(P) the set of common zeros of the Pj's in C n. Assuming that W is not included in V(P), one ...
