This book develops original results regarding singular dynamic
systems following two different paths. The first consists of
generalizing results from classical state-space cases to linear
descriptor systems, such as dilated linear matrix inequality (LMI)
characterizations for descriptor systems and performance control
under regulation constraints. The second is a new path, which
considers descriptor systems as a powerful tool for conceiving new
control laws, understanding and deciphering some controller's
architecture and even homogenizing different-existing-ways of
obtaining some new and/or known results for state-space systems.
The book also highlights the comprehensive control problem for
descriptor systems as an example of using the descriptor framework
in order to transform a non-standard control problem into a classic
stabilization control problem. In another section, an accurate
solution is derived for the sensitivity constrained linear optimal
control also using the descriptor framework. The book is intended
for graduate and postgraduate students, as well as researchers in
the field of systems and control theory.

A practical pocket-sized guide to the identification and use of
precious and semiprecious stones, novelty stones, agates and
crystals. The introductory part of the book describes the geology,
chemistry and properties of gemstones in clear and accessible
terms. The important properties of gemstones are explained,
including crystal structures and optical and physical properties,
and the book also examines synthetic gems and discusses how to tell
them apart from natural stones. It then covers practical aspects of
gemmology and the use of stones, including fashioning and cutting,
types and shapes of cut, collecting, handling and storing
gemstones, and weighing and measuring stones.
