Integration of declarative and constraint programming [PDF]

open access: yesTheory and Practice of Logic Programming, 2007
AbstractCombining a set of existing constraint solvers into an integrated system of cooperating solvers is a useful and economic principle to solve hybrid constraint problems. In this paper we show that this approach can also be used to integrate different language paradigms into a unified framework.

On the approximation of the set of trajectories of control system described by a Volterra integral equation

open access: yesNonlinear Analysis, 2014
In this paper, the set of trajectories of the control system described by a nonlinear Volterra integral equation is studied. It is assumed that the set of admissible control functions is the closed ball of the space Lp, p > 1, with radius µ and centered ...

Depth mapping of integral images through viewpoint image extraction with a hybrid disparity analysis algorithm [PDF]

open access: yes, 2008
Integral imaging is a technique capable of displaying 3–D images with continuous parallax in full natural color. It is one of the most promising methods for producing smooth 3–D images.

Constraint Based Planning with Composable Substate Graphs. [PDF]

open access: yes, 2010
Constraint satisfaction techniques provide powerful inference algorithms that can prune choices during search. Constraint-based approaches provide a useful complement to heuristic search optimal planners.We develop a constraint-based model for cost ...

Integration of Integrity Constraints in Database Federations [PDF]

open access: yes, 2004
A database federation provides for tight coupling of a collection of heterogeneous legacy databases into a global integrated system. A major problem in constructing database federations concerns maintaining quality and consistency of data on the global level of the federation.

Improved Barrier Function With Adjustable Parameter-Based Tracking Control for Robot Under Position Constraints

open access: yesIEEE Access, 2023
An improved time-variant asymmetric integral barrier function with adjustable parameters is constructed for the first time in this study. The presented barrier function, which is constructed by designing an integral upper limit function, can be used in ...

Effective compilation of constraint models [PDF]

open access: yes, 2010
Constraint Programming is a powerful technique for solving large-scale combinatorial (optimisation) problems. However, it is often inaccessible to users without expert knowledge in the area, precluding the wide-spread use of Constraint Programming ...

A modification of the convective constraint release mechanism in the molecular stress function model giving enhanced vortex growth [PDF]

open access: yes, 2006
YesThe molecular stress function model with convective constraint release (MSF with CCR) constitutive model [J. Rheol. 45 (2001), 1387] is capable of fitting all viscometric data for IUPAC LDPE, with only two adjustable parameters (with difference found ...

Breaking conditional symmetry in automated constraint modelling with CONJURE [PDF]

open access: yes, 2014
This work was supported by UK EPSRC EP/K015745/1. Jefferson is supported by a Royal Society University Research Fellowship.Many constraint problems contain symmetry, which can lead to redundant search.
