The Infoterra/TerraSAR initiative started as an industrial concept to provide X- and L-band SAR data products from a pair of spacecraft in Sun-synchronous orbit. The mission was proposed by the BNSC and DLR for implementation as an element of the ESA’s Earth Watch programme.

Fuzzy L-systems are presented as a formal mechanism for generating fuzzy formal languages. This provides a mechanism for modelling development while also incorporating the vagueness inherent to most real world processes. In this paper, fuzzy L-systems are defined, a normal form is developed, closure properties of fuzzy L-systems—both language-theoretic

This paper proposes the concept of generalized L systems, GL systems for short, which can describe asynchronized concurrent phenomena. We have proved that the GL systems are proper extensions of the traditional L systems. We have also defined a classification of GL systems and proved a sufficient and necessary condition for the equivalence of two ...

In geometry objects are often defined by explicit rules and transformations which can easily be translated into mathematical formulae. For example, a circle is the set of all points which are at a fixed distance r from a centre. In contrast to this, the objects of fractal geometry are usually given by a recursion.

In this chapter we consider special types of L-systems and study the properties of their transfer functions. In the first two sections we will use the notion of an auxiliary canonical system to prove a theorem about the constant J-unitary factor. The theorem states that if an operator-valued function W(z) belongs to the class Ω0(R,J) described in ...

A new type of development array system called Table Matrix L system is studied. In any rectangular array derivation takes place row by row or column by column restricted by tables so as to make the resultant array rectangular. The motivation for this is to find a development type of system which could generate interesting picture classes.
