Dynamic modulus is a key evaluation index of the high-modulus asphalt mixture, but it relatively difficult to test and collect its data. The purpose achieve accurate prediction dynamic mixture further optimize design process mixture. Five high-temperature performance indexes were selected. correlation between above five was analyzed. On this basis, models based on small sample data established ...

in this research, the influence of adding micro- and nano- sized calcium carbonate powders to nylon-66 was investigated. mechanical properties of micro and nano- composites, including tensile strength, elongation, and young’s modulus, before and after ageing, were determined and analyzed. for this purpose, micro- and nano-sized caco3 particles were used as fillers to prepare micro-composites (c...

Soil properties play a crucial role in understanding the mechanisms of erosion and consequently developing appropriate mitigation strategies. The aim this study is to determine elastic parameters soil an erosion-prone area using Multichannel Analysis Surface Wave (MASW) method geophysical exploration. active MASW was adopted for study. Data were acquired 24-channel ABEM Terralock MATK-6 seismog...

shear modulus and damping ratio are important input parameters in dynamic analysis. a series of resonant column tests was carried out on pure clays and sand-clay mixtures prepared at different densities to investigate the effects of aggregate content, confining stress, void ratio and clay plasticity on the maximum shear modulus and minimum damping ratio. test results revealed an increase in the...

We prove an interpolation theorem for rational circle diffeomorphisms: A set of N complex numbers of unit modulus may be mapped to any corresponding set by a ratio of polynomials p(z)/q(z) which restricts an invertible mapping of the unit circle S ⊂ C onto itself.

General Lucas sequences are practically useful in cryptography. In the past quarter century, factoring large RSA modulo into its primes is one of the most important and most challenging problems in computational number theory. A factoring technique on RSA modulo is mainly hindered by the strong prime properties. The success of factoring few large RSA modulo within the last few decades has been ...

blown bitumen (110/10) was mixed with heavy vacuum slops (h.v.s), 60/70 penetration grade bitumen and recycled isotactic polypropylene (ipp) at different levels. the resulting resins were used to impregnate non-woven poly(ethylene terephthalate) fibers to form composites. the modulus and penetration grade of the resulting bituminous resins were determined. it was found that these bituminous res...

Let PΩ → 2. In [15], the authors address the invariance of Thompson–Kovalevskaya, linearly separable curves under the additional assumption that ‖S′′‖ 6 = |W ′|. We show that there exists a co-algebraically Pascal and Frobenius anti-parabolic, reducible, combinatorially maximal modulus. Here, connectedness is trivially a concern. Recently, there has been much interest in the characterization of...

We report the synthesis of a three-dimensional (3D) macroassembly of graphene sheets with electrical conductivity (∼10(2) S m(-1)) and Young's modulus (∼50 MPa) orders of magnitude higher than those previously reported, super-compressive deformation behavior (∼60% failure strain), and surface areas (>1300 m(2) g(-1)) approaching theoretically maximum values.
