this study was conducted in order to evaluate the effects of long term ageing on toughness andresilient modulus of asphalt concrete mixtures containing electric arc and basic oxygen furnacesteel slags. after initial evaluation of the properties of steel slags using x-ray diffraction andscanning electric microscope, eleven sets of laboratory mixtures were prepared. each set wastreated replacing ...

A MASH digital delta–sigma modulator (DDSM) is analyzed mathematically. It incorporates first-order error feedback modulators (EFM) which include prime modulus quantizers to guarantee a minimum sequence length . The purpose of this analysis is to calculate the exact sequence length of the aforementioned MASH DDSM. We show that the sequence length for an th-order member of this modulator family ...

Higher-order α-corrections are a generic feature of type IIB string compactifications. In KKLT-like models of moduli stabilization they provide a mechanism of breaking the noscale structure of the volume modulus. We present a model of inflation driven by the volume modulus of flux compactifications of the type IIB superstring. Using the effects of gaugino condensation on D7-branes and perturbat...

The emergence of time in the matter-gravity system is addressed within the context of the inflationary paradigm. A quantumminisuperspace-homogeneous minimally coupled inflaton system is studied with suitable initial conditions leading to inflation and the system is approximately solved in the limit for large scale factor. Subsequently normal matter (either non homogeneous inflaton modes or ligh...

A discrete-time modulus consensus model is considered in which the interactions between the members of a networked family of n agents is described by a time-dependent gain graph whose vertices correspond to agents and whose arcs are assigned complex numbers from a prescribed cyclic group. Limiting behavior of the model’s state is studied using a graphical approach. It is shown that a certain ty...

We prove that if the initial condition of the Swift-Hohenberg equation tu(x; t) = "2 (1 + 2 x)2 u(x; t) u3(x; t) is bounded in modulus by Ce x as x ! +1, the solution cannot propagate to the right with a speed greater than sup 0< 1("2 + 4 2 + 8 4) : This settles a long-standing conjecture about the possible asymptotic propagation speed of the SwiftHohenberg equation. The proof does not use the ...

In this paper, an improved scheme is presented to investigate the approximate solutions of (2+1)-dimensional Boussinesq equation with initial conditions based on the decomposition method. The improve scheme makes all components ui of u = ∑∞ i=0 ui be of the same degree in t. We choose the (2+1)-dimensional Boussinesq equation with initial conditions of doubly-periodic functions to illustrate th...
