Durability of untreated fine recycled aggregate concrete: a literature review [PDF]

open access: yesMATEC Web of Conferences, 2022
Unlike natural aggregate particles, recycled concrete aggregates contain hardened cement paste phases and multiple interfacial transition zones. These differences in properties may be linked to a decrease in durability performance in recycled aggregate ...

Integration: Uniform structure

open access: yesJournal of Mathematical Analysis and Applications, 1991
In integration theory with respect to a finitely additive measure - as developed, e.g., by \textit{N. Dunford} and \textit{J. T. Schwartz} [Linear Operators. I (1958; Zbl 0084.104)] - a function is called integrable if it is the limit in measure of a \(\|\|_ 1\)-Cauchy sequence of simple functions.

Analysis of the Bauschinger Effect in Cold Drawn Pearlitic Steels

open access: yesMetals, 2020
Prestressing steel wires usually undergo cyclic loading in service. Therefore, it is of interest to analyse certain features of their mechanical behaviour under this type of loading, such as the Bauschinger effect (BE) or the hardening rule, that fit the

Logging Integrity with Blockchain Structures [PDF]

open access: yes, 2019
In developed countries, it is frequent for family members do not have the time, knowledge, or live in a close distance of their senior loved ones, so that many institutions offer their services to provide a good quality of life of older adults. To enable distributed local support, there is the need of digital platforms to allow the exchange of ...

Fault Identification in Pipeline System Using Normalized Hilbert Huang Transform and Automatic Selection of Intrinsic Mode Function

open access: yesMATEC Web of Conferences, 2018
Pressure transient analysis has been widely used to monitor the condition of pipelines and its assessment in water distribution systems. This is a low-cost nonintrusive technique with the ability to locate uncertainties (leak, pipe fitting, blockage) at ...

Influence of Loading Rate on the Hydrogen-Assisted Micro-Damage in Bluntly Notched Samples of Pearlitic Steel

open access: yesMetals, 2016
The influence of loading rate (crosshead speed) on the fracture process of bluntly notched samples of pearlitic steel under hydrogen environment is analyzed in this paper.

An integral formula for G2–structures

open access: yesJournal of Geometry and Physics, 2022
We apply an integral formula obtained by the author for a general $G$--structure to the case of $G=G_2$. We derive an integral formula relating curvatures and some quadratic invariants of the endomorphism induced by the intrinsic torsion. We interpret the formula in certain special cases.

The integrability problem for 𝐺-structures [PDF]

open access: yesTransactions of the American Mathematical Society, 1965
Introduction. One of the main problems of local differential geometry is to determine when a given differentiable structure (for example, a Riemannian structure, a projective structure or an almost complex structure) is integrable. There are really two problems involved in this: (1) the problem of finding a consistent system of differential equations ...
