ion and levels of abstraction are important concepts in the modeling space, but the terms are rarely used in this paper. The reason is that four kinds of abstraction are part of the modeling space, corresponding A UNIFORM COMPONENT MODELING SPACE Informatica 25 (2001) 475-482 477 to the three dimensions plus views. Instead of using the general ‘abstraction’ term, each kind is discussed in its o...

In this paper we discuss on the fixed points of asymptotic contractions and Boyd-Wong type contractions in uniform spaces equipped with an E-distance. A new version ofKirk's fixed point theorem is given for asymptotic contractions and Boyd-Wong type contractions is investigated in uniform spaces.

This work extends studies of Angluin, Lange and Zeugmann on the dependence of learning on the hypotheses space chosen for the class. In subsequent investigations, uniformly recursively enumerable hypotheses spaces have been considered. In the present work, the following four types of learning are distinguished: class-comprising (where the learner can choose a uniformly recursively enumerable su...

the existence of some geometrically imperfect members, like initial curvature in a double layer space structures with hundreds or thousands of members is almost inevitable. these imperfections give rise to loss of load bearing capacity of double layer space structures. to evaluate the effect of initial member imperfection on load bearing capacity of double layer space structures and their failu...

We obtain the uniform stability of recovering entire functions special form from their zeros. To such a form, we can reduce characteristic determinants strongly regular differential operators and pencils first second orders, including systems with asymptotically separated eigenvalues whose numbers lie on line containing origin, as well nonlocal perturbations these operators. prove that dependen...
