Abstract—Stable direct and indirect decentralized adaptive radial basis
neural network controllers are presented for a class of interconnected
nonlinear systems. The feedback and adaptation mechanisms for each
subsystem depend only upon local measurements to provide asymptotic
tracking of a reference trajectory. Due to the functional approximation
capabilities of radial basis neural NETWORKS, the dynamics for each
subsystem are not required to be linear in a set of unknown coeffi cients
as is typically required in decentralized adaptive schemes. In addition,
each subsystem is able to adaptively compensate for disturbances and
interconnections with unknown bounds.
Adaptive Coordinated Medium Access Control (AC-MAC), a contention-based Medium
Access Control protocol for wireless sensor NETWORKS. To handle the load variations in some real-time sensor applications, ACMAC
introduces the adaptive duty cycle scheme within the framework of sensor-MAC (S-MAC).
Abstract-In this paper, simple autonomous chaotic circuits
coupled by resistors are investigated. By carrying out computer
calculations and circuit experiments, irregular self-switching phenomenon
of three spatial patterns characterized by the phase
states of quasi-synchronization of chaos can be observed from
only four simple chaotic circuits. This is the same phenomenon
as chaotic wandering of spatial patterns observed very often from
systems with a large number of degrees of freedom. Namely, one
of spatial-temporal chaos observed from systems of large size can
be also generated in the proposed system consisting of only four
chaotic circuits. A six subcircuits case and a coupled chaotic circuits
NETWORKS are also studied, and such systems are confirmed
to produce more complicated spatio-temporal phenomena.
The goal of this thesis is the development of traffic engineering rules for cellular packet
radio NETWORKS based on GPRS and EDGE. They are based on traffic models for typical
mobile applications. Load generators, representing these traffic models, are developed
and integrated into a simulation environment with the prototypical implementation of
the EGPRS protocols and models for the radio channel, which were also developed in
the framework of this thesis. With this simulation tool a comprehensive performance
evaluation is carried out that leads to the traffic engineering rules.
Pattern Analysis is the process of fi nding general relations in a set of data,
and forms the core of many disciplines, from neural NETWORKS to so-called syn-
tactical pattern recognition, from statistical pattern recognition to machine
learning and data mining. Applications of pattern analysis range from bioin-
formatics to document retrieval.

In the next generation of wireless communication systems, there will be a need for the rapid
deployment of independent mobile users. Significant examples include establishing survivable, efficient,
dynamic communication for emergency operations, disaster relief efforts, and military NETWORKS. Such
network scenarios cannot rely on centralized and organized connectivity, and can be conceived as
applications of mobile ad hoc NETWORKS. A MANET is an autonomous collection of mobile users that
communicate over relatively bandwidth constrained wireless links. Since the nodes are mobile, the
