Stereo high-resolution satellite imagery, such as Space Imaging’s IKONOS (1 m resolution) and DigitalGlobe’s QuickBird (submeter resolution), can provide accurate three-dimensional (3D) mapping products. Based on the rational function model, this study investigated the integration of IKONOS and QuickBird images. One pair of stereo IKONOS images and one pair of stereo QuickBird images, collected...

In this paper we consider the problem of minimizing the C1 norm of a closed-loop transfer function while keeping its Hz norm under a specified level. It wiU be shown that the optimal closed-loop impulse response has finite support, and thus a non-rational Laplace transform. To solve this difficulty we propose & method for synthesizing rational controllers with performance arbitrarily close to o...

In this paper, the development of Indian Remote Sensing Satellite Serials is reviewed, the specifications of CARTOSAT-1 satellite platform and Sensor is introduced and compared with IKONOS、SPOT5 HRS. The positioning algorithm using Rational Function Model (RFM Model) of CARTOSAT-1 is described in detail. Experimentation is carried out using stereo pair of Beijing hilly area. The results show th...

We show that every inner divisor of the operator-valued coordinate function, zIE, is a Blaschke-Potapov factor. also introduce notion “rational” function and then Δ two-sided rational if only it can be represented as finite product; this extends to functions well-known result proved by V.P. Potapov for matrix-valued functions.

A permutation rational function f ∈ Fq(x) is a rational function that induces a bijection on Fq, that is, for all y ∈ Fq there exists exactly one x ∈ Fq such that f(x) = y. Permutation rational functions are intimately related to exceptional rational functions, and more generally exceptional covers of the projective line, of which they form the first important example. In this paper, we show ho...

The Isogeometric Analysis (IA) method is applied for structural topology optimization instead of the finite element method. For this purpose, the material density is considered as a continuous function throughout the design domain and approximated by the Non-Uniform Rational B-Spline (NURBS) basis functions. The coordinates of control points which are also used for constructing the density func...

Our aim is to study the set of K-rational expressions describing rational series. More precisely we are concerned with the definition of quotients of this set by coarser and coarser congruences which lead to an extension – in the case of multiplicities – of some classical results stated in the Boolean case. In particular, multiplicity analogues of the well known theorems of Brzozowski and Antim...
