✦ Synopsis

This paper presents an investigation into the utilisation of digital signal processing and parallel processing techniques for the real-time simulation of a flexible manipulator system. A finite dimensional simulation of the system is developed using a finite difference approximation to the governing dynamic equation of the manipulator. The proposed algorithm allows dynamic modification of the boundary conditions and the inclusion of a distributed actuator and sensor term in the system dynamic equation. The algorithm developed is implemented on a number of uni-processor and multi-processor, homogeneous and heterogeneous parallel architectures. The partitioning and mapping of the algorithm on the homogeneous and heterogeneous architectures is also explored. A comparison of the results of these implementations is made and discussed to establish merits of design and real-time processing requirements in the control of flexible manipulator systems.

## Abstract We present an extension of our previous theory describing aggregation processes in self‐associating polymer systems, i.e., in copolymers with strongly attracting groups. In particular, the formation and properties of micelles are studied in detail for the superstrong segregation regime.
