According to the direct homogenization theory of inhomogeneous material, a single medium homogenization constitutive model of the confined concrete in the steel box-concrete combined member has been established, and model parameters have been determined by the measured data of the bending test. By analyzing the theoretical ultimate strength and overall process curve, the results obtained is con...

In this article, perfectly matched layer (PML) for the boundary treatment and an efficient compact two dimensional finite-difference frequency-domain (2-D FDFD) method were combined to model photonic crystal fibers (PCF). For photonic crystal fibers, if we assume that the propagation constant along the propagation direction is fixed, threedimensional hybrid guided modes can be calculated by usi...

The quality and complexity demands of manufactured parts in sectors such as automotive aeronautics lead to narrower process windows. This affects the repeatability stability process, where material properties variations have a major impact. In bending processes, angle is affected by variability mechanical microstructural properties, especially high-strength materials. To address this, character...

The sheet metal bending process plays an important role in production and springback is unintended consequence of this operation. If the die performed without knowing amount springback, it difficult to produce parts within acceptable tolerance values. behavior part be bent also affects size die. In particular, case a 90° U bend die, manufacturing cost with compensation method high. Therefore, e...

This paper presents a new framework for recovering superquadrics with global deformations from multi-view real range data. The framework aims at improving confidence and accuracy of recovered models by utilizing multiview information, and consists of the initial superquadric model recovery, view registration, view integration, and final model recovery from integrated data. A quadrant analysis t...

This paper deals with boundary value problems for nonlinear monotone potential operators. An analysis of the nonlinear (monotone potential) Sturm–Liouville operator Au := − ( k((u′)2)u′(x) )′+q(x)u(x), x ∈ (a, b) shows that the potential of this operator as well as the potential of related boundary value problems play an important role not only for solvability of these problems, but also for li...

The stretching and bending vibrations of methane are studied in the framework of a symmetryadapted algebraic model. The model is based on the realization of the one-dimensional Morse potential in terms of a U(2) algebra. For the 45 observed energies we obtain a fit with a r.m.s. deviation of 1.11 cm which is an order of magnitude better than in any previous algebraic calculation. PACS numbers: ...

This paper offers a detailed, quantitative and exhaustive experimental comparison in terms of mechanical properties of three different layouts of carbon composite materials (CFRP) used to strengthen existing old timber beams highly affected by diverse natural defects and biological attacks, testing the use of pultruded laminate attached on the tension side of the element (LR), CFRP fabrics tota...

Escherichia coli (E. coli) is a large and diverse bacteria group that inhabits the intestinal tract of many mammals. Most E. coli strains are harmless, however some of them are pathogenic, meaning they can make one sick if ingested. By being in the feces of animals and humans, its presence in water and food is used as indicator of fecal contamination. The main method for this microorganism dete...
