The proposed models correlate the concrete true-triaxial strength (σ1) to mix design parameters and principal stresses (σ2,σ3), needless of conducting any time-consuming laboratory experiments.
Distinctive feature of Gene Expression Programming (GEP) has been employed to derive computer-aided prediction models for the multiaxial strength of concrete under true-triaxial loading.
Finally, the mortar of lime, sand, water, and pozzolana was mixed with stones and broken brick to form a true concrete, called opus caementicium.
But critics balked at the notion that any real talks had been offered before or that any true, concrete compromises — not just photo opportunities for a public fatigued by partisan rancor — were being offered now.
Dust generated from concrete drilling, particularly true for silica dust, have an adverse effect on the health of workers.
But there are also some concrete bits of true praise, which RIM deserves, especially when it comes to multitasking and communication management.
Arguably, that's what all poetry does, but there seems little doubt those initial colour-coded letters are concrete for him, true to his own synaesthetic experience.
From within the orthodox paradigm, one central piece of the mystery of intentionality can be brought out by reflection on the conditions in which simple singular thoughts about concrete individuals are true.
The majority of the high school students, during the conversations with us and each other, declared that they had finally connected the concept of natural selection and adaptations to "something concrete and to true experiences".
The two most popular models to obtain a size-independent specific fracture energy of concrete (also called true fracture energy (Karihaloo et al. 2003)) are the boundary effect model of Hu and Wittmann (1992) and the experimental correction model to avoid energy dissipations proposed by Guinea et al. (Elices et al. 1992; Guinea et al. 1992; Planas et al. 1992).
Negative rights (or duties) are concrete and always true whereas positive rights (or duties) to help are weaker but more encompassing.
