Sommario/riassunto |
|
Worldwide, there is a plethora of study materials in the form of authoritative review articles on disease entities afflicting the Western world but relatively few publications exploring similar problems confronting the developing countries, where resource limitation adds an extra dimension to the challenges facing the clinician. The contributions in this Reader address common surgical challenges and what measures have evolved to countenance these problems. This therefore addresses Current Surgical Practice, placing emphasis on the principles underlying the consensus opinions prevailing in |

Sommario/riassunto |
|
The main goal of this book is to prove analytically and validate experimentally that synchronization in multi-composed mechanical systems can be achieved in the case of partial knowledge of the state vector of the systems, i.e. when only positions are measured. For this purpose, synchronization schemes based on interconnections between the systems, feedback controllers and observers are proposed. Because mechanical systems include a large variety of systems, and since it is impossible to address all of them, the book focuses on robot manipulators. Nonetheless the ideas developed here can be |
