The study presents a possible innovative use of cement fiber boards (CFBs) reinforced with cellulose fibers for construction an interior prefabricated staircase. Regarding the unusual traditional material that was used in all bearing elements staircase, numerical simulation model SBETA carried out and, subsequently, multiple experimental static loading applied. In order to carry testing load ca...

Communicated June 30, 1964 The problem of the diffraction of obliquely incident scalar waves by finite slits and strips with various boundary conditions has been considered previously.' Reference may be made to the work of other authors on the diffraction of scalar waves by finite slits.2 The problem of the diffraction of obliquely incident vector elastic waves by a clamped finite strip has als...

A scattering description is proposed for a boundary perturbation of a c = 1 SL(2, Z) invariant conformal field theory. The bulk massless S-matrices are of the form of Zamolodchikov’s staircase model. Using the boundary version of the thermodynamic Bethe ansatz, we show that the boundary free energy goes through a series of integer valued plateaux as a function of system size.

The theory of the dynamic medium reference (DMR) has already been presented in several articles, particular, Pignard [Phys. Essays 32 , 422 (2019]. objective this article is to present gravitational waves within framework DMR theory. For this, an important relation established between potential and speed flux medium. This makes it possible deduce two differential equations verified by medium, o...

We have derived the perimeter generating function of a model of punctured staircase polygons in which the internal staircase polygon is rotated by a 90° angle with respect to the outer staircase polygon. In one approach we calculated a long series expansion for the problem and found that all the terms in the generating function can be reproduced from a linear Fuchsian differential equation of o...

Given a suitable encoding, any relational DBMS is able to answer queries on tree-structured data. However, conventional relational databases are generally not (made) aware of the underlying tree structure and thus fail to make full use of the encoded information. The staircase join is a new join algorithm intended to enhance the tree awareness of a relational DBMS. It was developed to speed up ...

Meandering spiral tips in homogeneous reaction-diffusion systems are characterized by two generically incommensurate radii and frequencies. Here, we create periodic perturbations in space to induce a transition to commensurate radii and frequencies that exhibit a devil's staircase. The plateaus of the staircase correspond to pinned or complex periodic orbits of the spiral tip.

This paper describes an interpolation method that takes into account the edge orientation in order to avoid typical interpolation artifacts (jagging, staircase effects...). It is first based on an edge orientation estimation, performed in the wavelet domain. The estimation uses the multi-resolution features of wavelets to give an accurate and non-biased description of the frequency characterist...
