A new method for algorithmically generating musical scores is presented and illustrated with examples. The idea is to produce a string of symbols using an L−system, and to interpret this string as a sequence of notes. The proposed musical interpretation of L−systems is closely related to their graphical interpretation, which in turn associates L−systems to fractals.

Elementary congestion models sometimes require analysis of G/G/l systems with hypere.xponentially distributed interarrival time and service time distributions. It is shown that for such systems, the ergodic waiting time distribution is itself hypere.xponentially distributed. A simple computational procedure is provided to fmd the parameters needed. Green's function methods are employed to motiv...

Chain Code Picture Systems are Lindenmayer systems over a special alphabet. The strings generated are interpreted as pictures. This leads to Chain Code Picture Languages. In this paper, synchronous deterministic Chain Code Picture Systems (sD0L systems) are studied with respect to the finiteness of their picture languages. First, a hierarchy of abstractions is developed, in which the interpreta...

L-Systems have been extensively utilized in plant modeling and music rendering. However, the music generated was not very pleasant as the grammars used are very simple. This paper describes a hybrid method that generates more complex grammars for L-Systems in a visual language framework for music rendering so that the musical sounds generated can be improved and fine-tuned. The method which use...

We present a method based on a 3D model converter to simulate the development of virtual plant. The converter is mainly used to import the plant organs which have fine details into the virtual plant development system, then communicating with the L-system to implement the simulation of the development of plants controlled by the physiology of plant. It improves the virtual effect that carried o...

In the present paper, synchronous, tabled chain code picture systems based on Lindenmayer systems (sT0L systems) are studied with respect to the finiteness of their picture languages. The finiteness is proved to be decidable. Additionally, a method is given for deciding whether an sT0L system generates a finite picture language or not.

This paper characterizes the development of modular branching structures that satisfy three assumptions: (a) subapical branching, meaning that new branches can be created only near the apices of the existing branches, (b) nite number of module types and states, and (c) absence of interactions between coexisting components of the growing structure. These assumptions are captured in the notion of...
