In this work, we explore the influence of grain size distribution (GSD) on density, connectivity and internal forces distributions, for both 2D 3D granular packings built mechanically. For power law GSDs, show that there is an exponent which density are optimized, close to those characterize other well known GSDs such as Fuller Thompson Appollonian packing. addition, studied distributions norma...

infectious bursal disease virus (ibdv) is the causative agent of gumboro disease, an infectious disease of global economic importance in poultry. structural protein vp2 of ibdv is the most frequently studied protein due to its significant roles in virus attachment, protective immunity, and serotype specificity. the objective of the present study was to improve the expression of hypervariable re...

the purpose of this study was to design and optimize an oral controlled release acyclovir mucoadhesive tablet, in term of its drug release and mucoadhesive strength. a 32 full factorial design was employed to study the effect of independent variables like carbopol-934p and hydroxypropyl methylcellulose k100m, which significantly influence characteristics like swelling index, ex-vivo mucoadhesiv...

For molecules containing second row atoms, unacceptable errors have been found in extrapolating dissociation energies calculated with the standard correlation consistent basis sets to the complete basis set limit. By carefully comparing the convergence behavior of De(O2) and De(SO), we show that the cause of these errors is a result of two inter-related problems: near duplication of the exponen...

Convergence of an s-wave calculation of the He ground state. The Configuration Interaction (CI) method using a large Laguerre basis restricted to = 0 orbitals is applied to the calculation of the He ground state. The maximum number of orbitals included was 60. The numerical evidence suggests that the energy converges as ∆E N ≈ A/N 7/2 + B/N 8/2 +. .. where N is the number of Laguerre basis func...

We consider the classical Neymann–Pearson hypothesis testing problem of signal detection, where under null ( ${\mathcal{ H}}_{0}$ ), received is white Gaussian noise, and alternative H}}_{1}$ includes also an additional non–Gaussian r...

We develop a passive control strategy for suppressing thermoacoustic instability in bluff-body stabilized premixed turbulent combustor. When the equivalence ratio is varied, there transition from combustion noise to via intermittency perform simultaneous acoustic pressure, 2D-PIV, and CH* chemiluminescence measurements capture pressure fluctuations, velocity field, heat release rate (HRR) field...

In this course we will present the full proof of the fact that every smooth dynamical system on the interval or circle X, constituted by the forward iterates of a function f : X → X which is of class Cr with r > 1, admits a symbolic extension, i.e., there exists a bilateral subshift (Y, S) with Y a closed shift-invariant subset of Λ, where Λ is a finite alphabet, and a continuous surjection π :...

Loynes’ distribution, which characterizes the one dimensional marginal of the stationary solution to Lindley’s recursion, possesses an ultimately exponential tail for a large class of increment processes. If one can observe increments but does not know their probabilistic properties, what are the statistical limits of estimating the tail exponent of Loynes’ distribution? We conjecture that in b...
