TL;DR: In this paper, the authors studied strongly rpp-semigroups whose set of idempotents forms a right regular band and the relation is a congruence, and they gave a tighter description of the semilattice decomposition involving a system of connecting maps, which can always construct a right C-rpp semigroup by glueing up the given ingredients by the connecting maps.
Abstract: We study the strongly rpp-semigroups whose set of idempotents forms a right regular band and the relation ${\cal L}^* \vee {\cal R}$ is a congruence. This kind of strongly rpp-semigroups was called by Y.Q. Guo the right C-rpp semigroups and he characterized them as semilattice of direct products of left cancellative monoid with right zero semigroup. The aim of this paper is to improve upon Guo’s result, giving a tighter description of the semilattice decomposition involving a system of connecting maps. By using our result, we can always construct a right C-rpp semigroup by glueing up the given ingredients by the connecting maps. An example of an infinite right C-rpp semigroup is constructed.

TL;DR: For the discrete linear nonstationary plants, the state or output feedbacks were designed for which the generalized H∞-norm of a closed-loop system characterizing the joint effect of initial state and external perturbation on the controlled output and terminal state takes on the minimal value.

TL;DR: In this article, the bearing capacity of the foundation base with long-term non-linear deformation of clay soils under the regime of cyclic prolonged static loading is calculated, where the base is considered a solid phase of development zones limit equilibrium, which is achieved for the foundation bases at the end of the formation of a hard core, deforming the ground.

TL;DR: In this paper, the authors investigated the dependence between the first cross-frequency single-storey buildings and a frequency of a single block and showed the effect of the ratio of stiffness of horizontal and vertical elements of a building on the value of the first natural vibrations frequency.
