Abstract The use of conventional reinforced concrete in the construction industry increases each year, especially developing countries. However, content, particularly cement production contributed to greenhouse gas emission subsequently increase climate change. Thus, slab containing high-density polyethene (HDPE) hollow spherical plastic bubble balls also known as deck slabs were introduced for...

Timber-concrete composite (TCC) slabs play an essential role in modern timber construction. Consisting of a member the tension zone, concrete layer compression zone and shear connection between two parts, TCC feature number advantages that make them ideally suitable for use both office residential buildings. However, currently used slab systems carry loads only one direction. In frame large res...

We demonstrate that one-way electromagnetic modes could be sustained by the edge of a gyromagnetic photonic crystal slab of triangular lattice under an external dc magnetic field. The applied magnetic field breaks the time-reversal symmetry of the three-dimensional system, and thus the original degeneracy point in k space, at which two dispersion surfaces intersect, is lifted, resulting in a ph...

In this paper, an attempt has been taken to find out optimum thickness of edge-supported slabs. To arrive at optimum solution using artificial neural network based on back-propagation network, a number of architectures such as 5-15-25-35-45-55-5; 5-25-35-45-55-65-85-105-5 and 5-35-45-65-75-85-5 with different number of hidden layers and hidden nodes or neuron were tried. Among them, 5-25-35-45-...

Let P be a point set of n points in R. Every point has a label/color (say black or white), but we do not know the labels. In particular, let B and W be the set of black and white points in P . Furthermore, let ∆ = diam(P ), and assume that there exist two parallel hyperplanes h, h′ in distance γ from each other, such that the slab between h and h′ does not contain an point of P , and the points...

Objective: To evaluate the influence of the surface used for manipulation (paper block and glass slab) on the mechanical properties (flexural strength and elastic modulus) and ion release (F) of two resin modified glass ionomer cements (RMGIC). Methods: Two RMGICs: Vitro Fil LC (DFL) and Riva Light (SDI) were used. The materials were manipulated on two different surfaces: block of paper and gla...

It is demonstrated that a waveguide consisting of two dielectric slabs may become an all-optical spring when guiding a superposition of two transverse evanescent modes. Both slabs are transversally trapped in stable equilibrium due to the optical forces developed. A condition for stable equilibrium on the wavenumbers of the two modes is expressed analytically. The spring constant characterizing...
