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 ...

Artificial neural networks in estimating marine propeller cavitation
(2002)Cavitation in marine propellers can be a serious problem that may result in severe deterioration in performance. This is particularly important in heavily loaded propellers, commonly encountered in small craft. Efforts ...

Assignment of natural frequencies by an added mass and one or more springs
(2004)The problem of assigning natural frequencies to a multi-degree-of-freedom undamped system by an added mass connected by one or more springs is addressed. The added mass and stiffnesses are determined using receptances from ...

Bogoyavlensky-Volterra and Birkhoff integrable systems
(2004)In this paper we examine an interesting connection between the generalized Volterra lattices of Bogoyavlensky and a special case of an integrable system defined by Sklyanin. The Sklyanin system happens to be one of the ...

Cessation of Couette and Poiseuille flows of a Bingham plastic and finite stopping times
(2005)We solve the one-dimensional cessation Couette and Poiseuille flows of a Bingham plastic using the regularized constitutive equation proposed by Papanastasiou and employing finite elements in space and a fully implicit ...

Comparison of a nonlinear adaptive controller with certainty-equivalence type adaptive controllers
(IEEE, 1995)Recently a new class of adaptive controllers for linear time invariant minimum phase plants has been proposed and analyzed. The design of these controllers is based on nonlinear tools and appears to be different from that ...

Comparison of two methods for the computation of singular solutions in elliptic problems
(1997)We compare two numerical methods for the solution of elliptic problems with boundary singularities. The first is the integrated singular basis function method (ISBFM), a finite-element method in which the solution is ...

The complexity of pure equilibria in mix-weighted congestion games on parallel links
(2015)We revisit the simple class of weighted congestion games on parallel links [10], where each player has a non-negative weight and her cost on the link she chooses is the sum of the weights of all players choosing the link. ...

Computing Nash equilibria for scheduling on restricted parallel links
(2004)We consider the problem of routing n users on m parallel links, under the restriction that each user may only be routed on a link from a certain set of allowed links for the user. Thus, the problem is equivalent to the ...

Conforming Chebyshev spectral methods for Poisson problems in rectangular domains
(1993)Four and six-element conforming domain decomposition techniques are developed for Chebyshev spectral collocation methods for Poisson problems in rectangular domains. The applicability of the methods is demonstrated on ...

Conforming spectral methods for Poisson problems in cuboidal domains
(1994)A Chebyshev collocation strategy is introduced for the subdivision of cuboids into cuboidal subdomains (elements). These elements are conforming, which means that the approximation to the solution is C0 continuous at all ...

A convex programming approach to the multiobjective H2/H∞ problem
(2002)In this paper, Banach space duality theory for the multiobjective H2/H∞ problem developed recently by the authors, is used to develop algorithms to solve this problem by approximately reducing the dual and predual ...

The d-identifying codes problem for vertex identification in graphs: Probabilistic analysis and an approximation algorithm
(2006)Given a graph G(V, E), the identifying codes problem is to find the smallest set of vertices D ⊆ V such that no two vertices in V are adjacent to the same set of vertices in D. The identifying codes problem has been applied ...

Direct routing: Algorithms and complexity
(2006)Direct routing is the special case of bufferless routing where N packets, once injected into the network, must be delivered to their destinations without collisions. We give a general treatment of three facets of direct ...

Least-cost transition firing sequence estimation in labeled petri nets
(2006)This paper develops a recursive algorithm for estimating the least-cost transition firing sequence(s) based on the observation of a sequence of labels produced by transition activity in a given labeled Petri net. Each ...

A Legendre spectral Galerkin method for the biharmonic Dirichlet problem
(2001)A Legendre spectral Galerkin method is presented for the solution of the biharmonic Dirichlet problem on a square. The solution and its Laplacian are approximated using the set of basis functions suggested by Shen, which ...

Looking for the integrating factor: The darboux approach
(2014)We present a method for the solution of first-order ordinary differential equations based on a class of polynomials known as Darboux polynomials. Integrating factors, used to convert the equations in exact form, and constants ...

Matrix decomposition algorithms for modified spline collocation for Helmholtz problems
(2003)We consider the solution of various boundary value problems for the Helmholtz equation in the unit square using a nodal cubic spline collocation method and modifications of it which produce optimal (fourth-) order ...

Measurement of partial widths and search for direct CP violation in D 0 meson decays to K-K+ and π -π+
(2005)We present a measurement of relative partial widths and decay rate CP asymmetries in K- K+ and π-π+ decays of D0 mesons produced in pp̄ collisions at,√s = 1.96 TeV. We use a sample of 2 × 105 D*+ →D0π+ (and charge conjugate) ...

Measurement of the decay amplitudes of B0 → J/ψK*0 and Bs 0 → J/ψφ decays
(2000)A full angular analysis of both the B0 and Bs 0 decay modes was carried out. For this analysis, the B0 → J/ψK*0 and Bs 0 → J/ψφ decays were reconstructed. The obtained data were analyzed in detail.
