There has been an increasing use of modern digital signal processors (DSPs) in industrial control and other applications in the past few years. While courses offered in electrical and computer engineering disciplines cover such topics as mobile and digital communication, image and sound encoding and decoding, few courses focus on the use of DSPs in real-time control of electrical machinery and drives. Therefore, there is a growing need in industry for engineers who can perform control design and system integration for various applications in motor control. This paper describes a course on Control of Electrical Machines offered by the School of Industrial Engineering of Barcelona (ETSEIB), Polytechnic University of Catalonia (UPC), Barcelona, Spain. A description of a hands-on laboratory testbed for motor control. An outline of the course structure, the laboratory setup and the design aspects for implementing modern real-time motor control applications are presented. [ABSTRACT FROM AUTHOR]

The European digitization and technological convergence process has served to deepen the crisis that all public broadcasters have been experiencing in Europe over the last 20 years. Yet, when the transition to digital broadcasting is discussed, this has mainly referred to the medium of television. Radio on the other hand, a medium with greater capillarity (in the sense of having deeper local roots and networks), has been dealing with its own crisis. This article outlines the main characteristics and problems of public service radio in Catalonia, arising from a study carried out on its structure and the programming it offers.
