Experimental Synchronization by Means of Observers

Experimental Transmission of African Horse-Sickness by Means of Mosquitoes

Partial Observers and Partial Synchronization

Traditionally, in engineering science, observer techniques most often deal with control problems. However, the potential of the theory on nonlinear observers [Njimejier & Mareels, 1997; Krener & Respondek, 1983; Xia & Gao, 1989] lies far beyond the area of control applications. Let us discuss a naive but illustrative example. Suppose a physician can monitor through a set of sensors some importa...

Experimental Evaluation of Shark Detection Rates by Aerial Observers

Aerial surveys are a recognised technique to identify the presence and abundance of marine animals. However, the capability of aerial observers to reliably sight coastal sharks has not been previously assessed, nor have differences in sighting rates between aircraft types been examined. In this study we investigated the ability of observers in fixed-wing and helicopter aircraft to sight 2.5 m a...

Quantitative analysis of chaotic synchronization by means of coherence.

We use an index of chaotic synchronization based on the averaged coherence function for the quantitative analysis of the process of the complete synchronization loss in unidirectionally coupled oscillators and maps. We demonstrate that this value manifests different stages of the synchronization breaking. It is invariant to time delay and insensitive to small noise and distortions, which can in...

Chaos synchronization: from the genesis to polytopic observers

This paper focuses on chaos synchronization. The history of this famous problem is traced from an automatic control point of view. First, it is recalled the two synchronization schemes introduced by Pecora and Carroll in 1990 called heterogeneous and homogeneous driving. Then, it is described how chaos synchronization has turned into an observer design problem during the years 1997s. Finally, t...
