In certain signal processing problems, it is customary to estimate parameters in distorted signals by approximating what is termed a cross ambiguity function and estimating where it attains its maximum modulus. To unify and generalize these procedures, we consider a generalized form of the cross ambiguity function and give error bounds for estimating the parameters, showing that these bounds ar...

The number of joints existing in the rock affects elastic modulus rock, and relationship has not been obtained. In this paper, 10 numerical models are established by simulations to study effect parallel on size modulus. research shows that there is a power function between joints, negative exponential size, their special mathematical given. paper also obtains form relationships characteristic m...

The apparent mechanical properties of hydroxyapatite (HA) whisker reinforced polyetherketoneketone (PEKK) scaffolds were evaluated in unconfined, uniaxial compression to investigate the effects of the porosity (75%, 82.5% and 90%), HA content (0, 20 and 40 vol%) and mold temperature (350, 365 and 375 ( composite function)C). Increased porosity resulted in a non-linear decrease in the elastic mo...

which is the precision to which F approximates K. An instance of classical interest is that in which L is C([0, 1]), K is A"—i.e. those functions bounded by one, and whose modulus of continuity is dominated by the modulus of continuity function o>—and F is the family Pn of polynomials of degree n 1. For this case it is known that there are positive constants A and B, independent of to and n, su...

Using positional data from video microscopy, we determine the elastic moduli of two-dimensional colloidal crystals as a function of temperature. The moduli are extracted from the wave-vector-dependent normal-mode spring constants in the limit q-->0 and are compared to the renormalized Young's modulus of the Kosterlitz-Thouless-Halperin-Nelson-Young theory. An essential element of this theory is...

Recently, a mixed hybrid operator, generalizing the well-known Phillips operators and Baskakov-Szász type operators, was introduced. In this paper, we study Bézier variant of these new operators. We investigate the degree of approximation of these operators by means of the Lipschitz class function, the modulus of continuity, and a weighted space. We study a direct approximation theorem by means...

INTRODUCTION AND OBJECTIVES Regional variations in the incidence of vascular diseases have been related to regional differences in arterial viscoelasticity. The aim of this study was to characterize the differences in the elastic and viscous modulus and in wall buffering function between central and peripheral systemic arteries, through a time-series analysis of the pressure-diameter relationsh...

The rheological response of polyisobutylene (PIB) solutions in Decalin and a related standard fluid Sl has been charac~~zed in dynamic oscillatory flow, step strain, step-shear rate and steady shear using a Rheometrics RDSII rheometer. The time dependence represented as a discrete spectrum of relaxation times and the strain dependence characterized as an exponential damping function have been p...

Let X be a compact, smooth, connected, Riemannian manifold without boundary, G : X×X → R be a kernel. Analogous to a radial basis function network, an eignet is an expression of the form PM j=1 ajG(◦, yj), where aj ∈ R, yj ∈ X, 1 ≤ j ≤ M . We describe a deterministic, universal algorithm for constructing an eignet for approximating functions in L(μ;X) for a general class of measures μ and kerne...

We develop a theory of modulus sheaves with transfers, which generalizes Voevodsky's transfers. This paper and its sequel are foundational for the motives modulus, is developed in [KMSY20].
