Among thin-walled structures, including building structures and constructions, shells of complex geometry are effective in their rigidity and strength characteristics, which are also distinguished by architectural harmony. For a wider application of

The paper concerns the engineering design of guide vane and runner blades of hydraulic turbines using the inverse problem on the basis of the definition of a velocity hodograph, which is based on Wu’s theory [1, 2]. The design concerns the low-head

In this paper, a novel fuzzy identification method for dynamic modelling of quadrotors UAV is presented. The method is based on a special parameterization of the antecedent part of fuzzy systems that results in fuzzy-partitions for antecedents. This

We formulate the Riemannian calculus of the probability set embedded with $$L^2$$ -Wasserstein metric. This is an initial work of transport information geometry. Our investigation starts with the probability simplex (probability manifold) supported o

A formula giving the exact error term for convergents of quadratic numbers is given. This formula is applied to Markoff forms and Markoff irrationalities: characterization of the smallest values of the form (the minimum being the corresponding Markof

We propose a method for determining parameters in the Schwarz–Christoffel integral. The desired mapping embeds into a one-parametric family of conformal mappings of the upper half-plane onto the family of polygons which was obtained by shifting one

Our aim is to study the Christoffel product of a D-Lagurre–Hahn form u of class $$s_{u}$$ by a polynomial of one degree. The obtained new form $${\widetilde{u}}$$ is also D-Lagurre–Hahn of class $$s_{{\widetilde{u}}}$$ with $$s_{u}-1\le s_{{\wide

Wave‐mode separation is a critical step in anisotropic elastic‐wave imaging. To avoid high computational costs and additional corrections, we apply a separation formula in the space domain that projects Cartesian components of the elastic wavefie
