Strengthening of concrete structures is applied as a solution for various deterioration problems in civil engineering practice. This paper presents an analytical study the behaviour cross-section reinforced (RC) beam, strengthened flexure with fiber polymer (FRP) materials. Using balance internal forces cross section through all phases stress which passes, program was written MATLsoftware, exec...

Abstract With analytical representation for the pp scattering amplitudes introduced and tested at lower energies, a description of high precision is given $$d\sigma /dt$$ d σ / t data $$\sqrt{s}= 13$$ s </mm...

Connections with Reduced Beam Section (RBS) have been investigated in the last 20 years both from an analytical point of view and from an experimental point of view. Several experimental tests demonstrated that RBS connections designed according to themost modern seismic codes are able to obtain the desired goal: the protection of the connection due to the yielding of the adjacent RBS. But in a...

introduction: medicine is an inseparable link of health chain; a flaw in health process for high expenditures of the medicine or inappropriate access shall certainly bring higher costs in the mentioned procedure. the present study aimed to evaluate the impact of the households’ income, geographical access, patients’ direct payment, physician's visit and insured' inpatient rate on the amount of ...

We examine a numerical technique developed to simulate unsteady dispersion and diffusion in coated tubes of arbitrary but axially-constant cross-section. The method is validated against analytical asymptotic solutions produced for tubes of circular section, then applied to the study of dispersion in equivalent tubes of square section, coated on one, two, three or four walls, and in a family of ...

In refs. [1, 2] it was demonstrated that the total cross section of the scattering of two light particles (zero modes of the Kaluza-Klein tower) in the six-dimensional λφ 4 model differs significantly from the cross section of the same process in the conventional λφ 4 theory in four space-time dimensions even for the energies below the threshold of the first heavy particle. Here the analytical ...

This Appendix is organized as follows. First, in Section A.1, we discuss a variant of a static disclosure model that provides a numerical result and analytical insights we later use in the proof of Proposition 1. This variant of the static model may also be of independent interest. Then, in Section A.2 we provide a proof of the Proposition. The proof starts with noticing properties of the equil...

Consider the p-system describing the subsonic flow of a fluid in a pipe with section a = a(x). We analyze the mathematical problem related to a junction, i.e., a sharp discontinuity in the pipe’s geometry, we consider the case of a picewise constant pipe’s section and then, the smooth case. In particular, through a limit procedure, we prove the well posedness of the smooth case from the discont...
