Introduction to the Special Section

ystem identification refers broadly to the problem of developing empirical mathematical models of systems based on excitation and response measurements. Such models are useful for enhancing physical understanding; analyzing system properties; and performing simulation, prediction, filtering, state estimation, monitoring, and fault diagnosis as well as control. Practical interest in system ident...

Introduction to the Special Section

I F we consider Zuse’s Plankalktil the first programming language, research on computer languages is about half a century old now. During this period, languages have always been in the mainstream of computer science research. The focus of the research has perhaps shifted somewhat from efficiency (1950s) to expressivity (196Os), portability (197Os), and handling complexity (198Os), but the inter...

Introduction to the special section: Galileo Mission results from the icy Galilean satellites

The four largest satellites of Jupiter, Io, Europa, Ganymede, and Callisto, have fascinated scientists since their discovery by Galileo in 1610. The four bodies, named the Galilean satellites in honor of their discoverer, represent what might be viewed as a miniature solar system, with planet-sized dimension, systematically changing densities, and as diverse a set of surface characteristics, ag...
