Let a(x), b(x), p(x) be formal power series in the indeterminate x over C (i.e., elements of the ring C [[x]] of such series) such that ord a(x) = 0, ord p(x) = 1 and p(x) is embeddable into an analytic iteration group (π(s, x))s∈C in C [[x]]. By a covariant embedding of the linear functional equation φ(p(x)) = a(x)φ(x) + b(x), (L) (for the unknown series φ(x) ∈ C [[x]]) with respect to (π(s, x...

The Advanced Identity Representation (AIR) Project is a new interdisciplinary approach to the problem of designing identity technologies to enable imaginative selfrepresentations for users by implementing dynamic social identity models grounded in computing and cognitive science. AIR Project research develops models of social computational identity (e.g., characters, avatars, and social network...

The many thousands of Aboriginal rock art sites extending across Australia represent an important cultural record. The styles and materials used to produce such art are of great interest to archaeologists and those concerned with the protection of these significant works. Through an analysis of the mineral pigments utilised in Australian rock art, insight into the age of paintings and practices...

In this work, we establish some efficient and practical design rules for the implementation of single-channel ultra-high speed (>160-Gbit/s) telecommunication systems based on dense dispersion management. Moreover, we analyze some of actual implementation issues such as slope compensation scenario, junction losses, polarization mode dispersion and chromatic dispersion fluctuations.

We generalize ∇(A), which was introduced in [Sch∞], to larger cardinals. For a regular cardinal κ > א0 we denote by ∇κ(A) the statement that A ⊆ κ and for all regular θ > κ, {X ∈ [Lθ[A] ] <κ : X ∩ κ ∈ κ ∧ otp(X ∩ Ord) ∈ Card} is stationary in [Lθ[A] ] . It was shown in [Sch∞] that ∇א1(A) can hold in a set-generic extension of L. We here prove that ∇א2(A) can hold in a set-generic extension of L...

Our multiscale air quality modeling activities are reviewed. Two different techniques, static grid nesting and dynamic grid adaptions are discussed. The mass conservation and transportive properties of our grid nesting technique are shown in a linear advection problem. Results from an air quality application to the northeastern U.S. are also presented. The solution accuracy with the adaptive gr...

Let C[[x1, . . . ,xn]] (brie£y C [[x]], where xˆ (x1, . . . ,xn) is the vector of indeterminates) be the ring of formal power series in n indeterminates x1, . . . ,xn with complex coe¤cients.We consider in this paper formal power series transformations F by which we understand automorphisms F of C[[x]] which are continuous with respect to the order topology (i.e., order preserving) and leave ev...

OCTOBER 2004 AMERICAN METEOROLOGICAL SOCIETY | he data supporting aerosol research can be obtained either observationally or indirectly from models. Observations can be broadly divided into routine monitoring efforts, which may be used to continuously evaluate an assimilation model, or episodically generated data, localized in space and/or time (Fig. 1). Assimilated monitoring results, if they ...

Terrestrial runoff and river input dominates urban pollutant loading rates Often draining directly into the surfzone, this pollution degrades surfzone water quality, leading to beach closures (e.g., Boehm et al., 2002), increases health risks (e.g., diarrhea and upper respiratory illness) (Haile et al., 1999), and contains both human viruses (Jiang and Chu, 2004) and elevated levels of fecal in...

In this Article dispersion characteristic of conventional optical waveguide with helical winding at core – cladding interface has been obtained. The model dispersion characteristics of optical waveguide with helical winding at core-cladding interface have been obtained for five different pitch angles. This paper includes dispersion characteristics of optical waveguide with helical winding, and ...
