H∞ Optimal Performance Design of an Unstable Plant under Bode Integral Constraint

open access: yesComplexity, 2018
This paper proposed the H∞ state feedback and H∞ output feedback design methods for unstable plants, which improved the original H∞ state feedback and H∞ output feedback.

Data integration under integrity constraints [PDF]

open access: yesInformation Systems, 2002
Data integration systems provide access to a set of heterogeneous, autonomous data sources through a so-called global schema. There are basically two approaches for designing a data integration system. In the global-as-view approach, one defines the elements of the global schema as views over the sources, whereas in the local-as-view approach, one ...

Prioritised fuzzy constraint satisfaction problems: axioms, instantiation and validation [PDF]

open access: yes, 2003
This paper identifies a generic axiom framework for prioritised fuzzy constraint satisfaction problems (PFCSPs), and proposes methods to instantiate it (i.e., to construct specific schemes which obey the generic axiom framework).

Sparse recovery with integrality constraints [PDF]

open access: yesDiscrete Applied Mathematics, 2020
We investigate conditions for the unique recoverability of sparse integer-valued signals from a small number of linear measurements. Both the objective of minimizing the number of nonzero components, the so-called $\ell_0$-norm, as well as its popular substitute, the $\ell_1$-norm, are covered.

Integrating Cardinality Constraints into Constraint Logic Programming with Sets [PDF]

open access: yesTheory and Practice of Logic Programming, 2021
AbstractFormal reasoning about finite sets and cardinality is important for many applications, including software verification, where very often one needs to reason about the size of a given data structure. The Constraint Logic Programming tool $$\{ log\} $$ provides a decision procedure for deciding the satisfiability of formulas involving very ...

On Solvability Conditions for the Cauchy Problem for Non-Volterra Functional Differential Equations with Pointwise and Integral Restrictions on Functional Operators

open access: yesMathematics, 2023
Cauchy problems are considered for families of, generally speaking, non-Volterra functional differential equations of the second order. For each family considered, in terms of the parameters of this family, necessary and sufficient conditions for the ...

On the compactness of the set of L-2 trajectories of the control system

open access: yesNonlinear Analysis, 2018
In this paper, the compactness of the set of L2 trajectories of the control system described by the Urysohn-type integral equation is studied. The control functions are chosen from the closed ball of the space L2 with radius r and centered at the origin.

An Approximation Method for Variational Inequality with Uncertain Variables

open access: yesAdvances in Mathematical Physics, 2023
In this paper, a Stieltjes integral approximation method for uncertain variational inequality problem (UVIP) is studied. Firstly, uncertain variables are introduced on the basis of variational inequality.

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.
