This book places IT in perspective by tracing its development through time, covering its origins in business, the massive expansion of the role of IT at the end of the 20th century, the growth of the internet, and the successes and failures of companies involved in this development. Despite its ubiquity in the modern world, the author highlights that efficient use of IT by businesses can only be gained by a good understanding of its potentials and pitfalls, highlighting how its informed use in practice is essential for companies to succeed. Finally, questions are raised concerning the future of IT: who will reap the benefits and why? Will IT continue to provide solutions and will it always deliver on its promise? Will it cease to advance and thus cease to be studied or will it continue to develop and thus provide new opportunities and challenges to users?

Revel probes the origins of the notion that America is the source of all evil: imperialistic, greedy, ruthlessly competitive - a hyperpower whose riches are acquired at the expense of the Third World.

Equilibrium and Transfer in Porous Media 3 A porous medium is composed of a solid matrix and its geometrical complement: the pore space. This pore space can be occupied by one or more fluids. The understanding of transport phenomena in porous media is a challenging intellectual task. This book provides a detailed analysis of the aspects required for the understanding of many experimental techniques in the field of porous media transport phenomena. It is aimed at students or engineers who may not be looking specifically to become theoreticians in porous media, but wish to integrate knowledge of porous media with their previous scientific culture, or who may have encountered them when dealing with a technological problem. While avoiding the details of the more mathematical and abstract developments of the theories of macroscopization, the author gives as accurate and rigorous an idea as possible of the methods used to establish the major laws of macroscopic behavior in porous media. He also illustrates the constitutive laws and equations by demonstrating some of their classical applications. The priority is to put the constitutive laws in concrete circumstances without going into technical detail. This third volume in the three-volume series focuses on the applications of isothermal transport and coupled transfers in porous media.

Synchronous motors are indubitably the most effective device to drive industrial production systems and robots with precision and rapidity. Their control law is thus critical for combining at the same time high productivity to reduced energy consummation. As far as possible, the control algorithms must exploit the properties of these actuators. Therefore, this work draws on well adapted models resulting from the Park’s transformation, for both the most traditional machines with sinusoidal field distribution and for machines with non-sinusoidal field distribution which are more and more used in industry. Both, conventional control strategies like vector control (either in the synchronous reference frame or in the rotor frame) and advanced control theories like direct control and predictive control are thoroughly presented. In this context, a significant place is reserved to sensorless control which is an important and critical issue in tomorrow’s motors.
