This is the seventh book containing examples from the Theory of Complex Functions. In this volume we shall apply the calculations or residues in computing special types of trigonometric integrals, some types of improper integrals, including the computation of Cauchy’s principal value of an integral, and the sum of some types of series. We shall of course assume some knowledge of the previous books and the corresponding theory.

In §5.8 and §5.10 we learned how to ﬁnd good polynomial approximations to a given function f (x) in a given interval a ≤ x ≤ b. Here, we want to generalize the task to ﬁnd good approximations that are rational functions (see §5.3).

Spatial or territorial organization is one of effective tools for sustainable land use. Spatial organization of land use and environmental protection by functional subareas is performed on the basis of comprehensive and integrated research on characteristics and differentiation laws of natural components and landscapes, socioeconomic factors, the present status and trend of environmental changes as well as the structures and functions of subareas. Uong Bi is a national center for tourism, coal mining and thermal power production.

Arabic morphology is complex, partly because of its richness, and partly because of common irregular word forms, such as broken plurals (which resemble singular nouns), and nouns with irregular gender (feminine nouns that look masculine and vice versa). In addition, Arabic morphosyntactic agreement interacts with the lexical semantic feature of rationality, which has no morphological realization. In this paper, we present a series of experiments on the automatic prediction of the latent linguistic features of functional gender and number, and rationality in Arabic.

The purpose of this chapter is largely to serve as an accessible introduction or a refresher of basic notions regarding analytic functions. We start by recalling the elementary theory of functions and their singularities in a style tuned to the needs of analytic combinatorics. Cauchy’s integral formula expresses coefficients of analytic functions as contour integrals. Suitable uses of Cauchy’s integral formula then make it possible to estimate such coefficients by suitably selecting an appropriate contour of integration.

In 1991, David Gale and Raphael Robinson, building on explorations carried out by Michael Somos in the 1980s, introduced a threeparameter family of rational recurrence relations, each of which (with suitable initial conditions) appeared to give rise to a sequence of integers, even though a priori the recurrence might produce nonintegral rational numbers. Throughout the '90s, proofs of integrality were known only for individual special cases. In the early '00s, Sergey Fomin and Andrei Zelevinsky proved Gale and Robinson's integrality conjecture.

With the introduction of genetic engineering of Escherichia coli by Cohen, Boyer and coworkers in 1973, the way was paved for a completely new approach to optimisation of existing biotech processes and development of completely new ones. This lead to new biotech processes for the production of recombinant proteins, e.g. the production of human insulin by a recombinant E. coli.

In the first step of synthesizing information, you developed use cases and usage scenarios to begin describing the current state of the business. The use cases describe the primary functionality of the business processes within a business. The usage scenarios provide the detail that describes how the functionality occurs in a business process.

Rational Function Interpolation and Extrapolation Some functions are not well approximated by polynomials, but are well approximated by rational functions, that is quotients of polynomials. We denote by Ri(i+1)...(i+m) a rational function passing through the m + 1 points (xi , yi ) . . . (xi+m , yi+m ). More explicitly, suppose Ri(i+1)...(i+m) = p 0 + p1 x + · · · + pµ x µ Pµ (x) = Qν (x) q 0 + q 1 x + · · · + q ν xν (3.2.1)

To the memory of Rodica Simion The goals of this paper are twofold. First, we prove, for an arbitrary ﬁnite root system Φ, the periodicity conjecture of Al. B. Zamolodchikov [24] that concerns Y systems, a particular class of functional relations playing an important role in the theory of thermodynamic Bethe ansatz. Algebraically, Y systems can be viewed as families of rational functions deﬁned by certain birational recurrences formulated in terms of the root system Φ.

Sums of two squares near perfect squares by R. C. Vaughan∗∗∗ In memory of Pritish Limani (1983–2003) Abstract Let C be a nondegenerate planar curve and for a real, positive decreasing function ψ let C(ψ) denote the set of simultaneously ψapproximable points lying on C. We show that C is of Khintchine type for divergence; i.e. if a certain sum diverges then the onedimensional Lebesgue measure on C of C(ψ) is full. We also obtain the Hausdorﬀ measure analogue of the divergent Khintchine type result. ...

For integer order, however, the routines in this section (and §6.6) are simpler and faster. Their only drawback is that they are limited by the precision of the underlying rational approximations. For full double precision, it is best to work with the routines for fractional order in §6.7. For any real ν, the Bessel function Jν (x) can be deﬁned by the series representation Jν (x) = 1 x 2 ν ∞ k=0

Let X be a projective manifold and f : X → X a rational mapping with large topological degree, dt λk−1 (f ) := the (k − 1)th dynamical degree of f . We give an elementary construction of a probability measure µf such that d−n (f n )∗ Θ → µf for every smooth probability measure Θ on X. We show t that every quasiplurisubharmonic function is µf integrable. In particular µf does not charge either points of indeterminacy or pluripolar sets, hence µf is f invariant with constant jacobian f ∗ µf = dt µf...

Another domain located, in part, in the realm beyond rationality and control is the study of learners’ interest. The study of interest has exam ined the degree to which learners’ are enjoying an activity or topic, pre fer one thing rather than another, and want to continue with an activity in the near and distant future. Of particular relevance to this essay is the attention given to the inspired, emergent quality of engaging experi ences (Renninger, Hidi, & Krapp, 1992). Their constructs of situational interest (a characteristic...
