In this paper an approach to recognizing objects on images is proposed. The approach is based on a logical inference using structural descriptions of objects. Searching boundary of objects on an image is performed as a unification of built-in predicate line satisfying a set of constraints defined by the description.
We extend the notion of flat inputs, which we previously introduced in the SISO case, towards non-linear MIMO systems. For MIMO systems, we have to distinguish two cases for differential flatness, corresponding to fee...

We study shapes of reachable sets to singularly perturbed linear controlsystems. The fast component of the phase vector is assumed to be governed by a hyperbolic linear system. We show that the shapes of reachable sets have a limit as the parameter ε of singular perturbation tends to zero. We also find a sharp estimate for the rate of convergence. Similar results for the reachable sets themselves, instead of shapes, were obtained previously for the case of stable fast component.

Nonlocal chiral quark model is self-consistently extended beyond mean field using a strict 1 / N c expansion scheme. The parameters of the nonlocal model are refitted to the physical values of the pion mass and the weak pion decay constant. The size of the 1 / N c correction to the quark condensate is carefully studied in the nonlocal and the usual local Nambu–Jona-Lasinio models. It is found that even the sign of the corrections can be different. This can be attributed to the mesonic cut-off of the local model. It is also found that the 1 / N c corrections lead to lowering of the temperature of the chiral phase transition in comparison with the mean-field result. On the other hand, near the phase transition the 1 / N c expansion breaks down and a non-perturbative scheme for the inclusion of mesonic correlations is needed in order to describe the phase transition point.
A method is proposed for the detection of statistical tables that use metafiles as input data;the latter fact allows one to apply this method to documents of different formats. In this method, the table detection proc...

We consider a controlsystem described by an evolution equation with control constraint which is a multivalued mapping of a phase variable with closed nonconvex values. One of the evolution operators of the system is ...
