This paper describes a novel instancebased sentence boundary determination method for natural language generation that optimizes a set of criteria based on examples in a corpus. Compared to existing sentence boundary determination approaches, our work offers three signiﬁcant contributions. First, our approach provides a general domain independent framework that effectively addresses sentence boundary determination by balancing a comprehensive set of sentence complexity and quality related constraints.

In relaxation problems, you have to choose values for the independent variable at the mesh points. This is called allocating the grid or mesh. The usual procedure is to pick a plausible set of values and, if it works, to be content. If it doesn’t work

have clients that say, “I never thought this would happen to me.” Throughout their twenties, when they only had themselves to look after, they did just that, thought about themselves. They made time for their friends, had nights out with the girls, painted their toenails and spent hours in the bath with their faces covered in some gooey, smelly substance that promised eternal youth

A critical point concerning this approach: As project manager, you must set boundaries on the range of tasks and also ensure that there is a complete understanding of task goals. For example, a project team member who is assigned the job of interpreting market test data will need you to tell him what tests to apply and to check conclusions with you before simply incorporating them into the final report. As project manager, you must stay in touch with the team, both to supervise when necessary and to be available if problems do arise.

ON A BOUNDARY VALUE PROBLEM FOR NONLINEAR FUNCTIONAL DIFFERENTIAL EQUATIONS ROBERT HAKL Received 21 August 2004 and in revised form 1 March 2005 We consider the problem u (t) = H(u)(t) + Q(u)(t), u(a) = h(u), where H,Q : C([a,b];R) αβ → L([a,b];R) are, in general, nonlinear continuous operators, H ∈ ab (g0 ,g1 , p0 , p1 ), and h : C([a,b];R) → R is a continuous functional. Eﬃcient conditions suﬃcient for the solvability and unique solvability of the problem considered are established. 1.

In the design of an integrated circuit, the designer is faced with the challenge of having circuits and systems function over multiple operating points. From the point of view of performance, the circuit must meet its speed requirements over a range of voltages and temperatures that reflect the environment that the circuit is operating in. Also while the performance requirement must be met at a set of worstcase conditions for speed, the power requirement must be simultaneously met at another set of worstcase conditions for power....

where φ(x) is chosen by us. Written in terms of the mesh variable q, this equation is dx ψ = dq φ(x) (17.5.7) Notice that φ(x) should be chosen to be positive deﬁnite, so that the density of mesh points is everywhere positive. Otherwise (17.5.7) can have a zero in its denominator. To use automated mesh spacing, you add the three ODEs (17.5.5) and (17.5.7) to your set of equations

BOUNDARY VALUE PROBLEMS FOR THE 2NDORDER SEIBERGWITTEN EQUATIONS CELSO MELCHIADES DORIA Received 8
BOUNDARY VALUE PROBLEMS FOR THE 2NDORDER SEIBERGWITTEN EQUATIONS CELSO MELCHIADES DORIA Received 8 June 2004 It is shown that the nonhomogeneous Dirichlet and Neuman problems for the 2ndorder SeibergWitten equation on a compact 4manifold X admit a regular solution once the nonhomogeneous PalaisSmale condition is satisﬁed. The approach consists in applying the elliptic techniques to the variational setting of the SeibergWitten equation. The gauge invariance of the functional allows to restrict the problem to the Coulomb subspace C of conﬁguration space.

Solving PDEs generally means you must take the time to set up the underlying equations, material properties, and boundary conditions for a given problem. COMSOL Multiphysics, however, relieves you of much of this work. The package provides a number of application modes that consist of predefined templates and user interfaces already set up with equations and variables for specific areas of physics. Special properties allow the selection of, for instance, analysis type and model formulations.

Since the establishment of the conductive properties of intrinsic conductive polymers, a huge variety of basic and applied research has been carried out, involving different polymers, copolymers, blends, mixtures and composites. Thus, fundamental understanding of physical and chemical properties of these materials has been sought, while the applied aspects have advanced very rapidly, crossing the boundaries between disciplines. Today, the applications of conducting polymers in various fields such as neuroscience, nanotechnology and green chemistry, are easily found.

Wavelets in Boundary Integral Equations Numerical treatment of integral equations can be found in classic books [1, 2]. In this chapter the integral equations obtained from ﬁeld analysis of electromagnetic wave scattering, radiating, and guiding problems are solved by the wavelet expansion method [3–7]. The integral equations are converted into a system of linear algebraic equations. The subsectional bases, namely the pulses or piecewise sinusoidal (PWS) modes, are replaced by a set of orthogonal wavelets.

In this paper we study Lipschitz solutions of partial diﬀerential relations of the form (1) ∇u(x) ∈ K a.e. in Ω, where u is a (Lipschitz) mapping of an open set Ω ⊂ Rn into Rm , ∇u(x) is its gradient (i.e. the matrix ∂ui (x)/∂xj , 1 ≤ i ≤ m, 1 ≤ j ≤ n, deﬁned for almost every x ∈ Ω), and K is a subset of the set M m×n of all real m × n matrices. In addition to relation (1), boundary conditions and other conditions on u will also be considered. Relation (1)...

A quantitative sharp form of the classical isoperimetric inequality is proved, thus giving a positive answer to a conjecture by Hall. 1. Introduction The classical isoperimetric inequality states that if E is a Borel set in Rn , n ≥ 2, with ﬁnite Lebesgue measure E, then the ball with the same volume has a lower perimeter, or, equivalently, that (1.1) 1/n nωn E(n−1)/n ≤ P (E) . Here P (E) denotes the distributional perimeter of E (which coincides with the classical (n − 1)dimensional measure of ∂E when E has a smooth boundary) and ωn is the measure of the...

This paper considers a trapped characteristic initial value problem for the spherically symmetric EinsteinMaxwellscalar ﬁeld equations. For an open set of initial data whose closure contains in particular ReissnerNordstr¨m data, o the future boundary of the maximal domain of development is found to be a lightlike surface along which the curvature blows up, and yet the metric can be continuously extended beyond it. This result is related to the strong cosmic censorship conjecture of Roger Penrose. ...

In this paper we improve an earlier result by Bukhgeim and Uhlmann [1], by showing that in dimension n ≥ 3, the knowledge of the Cauchy data for the Schr¨dinger equation measured on possibly very small subsets of the o boundary determines uniquely the potential. We follow the general strategy of [1] but use a richer set of solutions to the Dirichlet problem. This implies a similar result for the problem of Electrical Impedance Tomography which consists in determining the conductivity of a body by making voltage and current measurements at the boundary. ...
