Algorithmic discrete mathematics plays a key role in the development of information and communication technologies, and methods that arise in computer science, mathematics and operations research in particular in algorithms, computational complexity, distributed computing and optimization are vital to modern services such as mobile telephony, online banking and VoIP.

This book examines communication networking from a mathematical viewpoint. The contributing authors took part in the European COST action 293 a four-year program of multidisciplinary research on this subject. In this book they offer introductory overviews and state-of-the-art assessments of current and future research in the fields of broadband, optical, wireless and ad hoc networks. Particular topics of interest are design, optimization, robustness and energy consumption.

The book will be of interest to graduate students, researchers and practitioners in the areas of networking, theoretical computer science, operations research, distributed computing and mathematics."

From her home at 9 Adams Road in the university city of Cambridge, Alice Roughton (19001995) demonstrated a strongly altruistic lifestyle, housing young students, the mentally ill, artists, intellectuals, friends, persecuted homosexuals and refugees (German Jews in 1939, Hungarians in 1956 and Chileans in 1973). She practiced psychiatry and general medicine alongside personal activism such as medics against nuclear warfare and opposing the financing of urbanisation the latter related to the destruction of the historical centres of English cities. Alice was a patron of artists and intellectuals, including the Catalan musician Robert Gerhard and the German dancer Kurt Jooss. She befriended the economists J. M. Keynes and Joan Robinson, the philosopher Bertrand Russell, the astrophysicist Stephen Hawking, the molecular biologist James Watson, as well as the composer Benjamin Britten, who held memorable concerts at her house, as well as many other dignitaries of science and the humanities. The House of Alice Roughton locates her professional medical work and private life activities and relationships within the sociological circumstances within which she lived circumstances that reveal the historical and cultural changes of a century that experienced two world wars, the advance of science and the overturning of lifestyle prejudices. The biography revolves around one location 9 Adams Road. Alice and her familys lived experiences act as a window onto the profound global transformations which took place from the second industrial revolution to the discovery of the structure of DNA From the Edwardian to the Contemporary. Her familys life story moves through tragic events in Switzerland to her husbands war years in America. Her biographers engagement with Alice begins in 1978, on a student holiday trip from his native Catalonia.

Elemental segmentation techniques based on boundary or region approaches often fail to produce accurate segmentation results. Hence, in the last few years, there has been a tendency towards the integration of both techniques in order to improve the results by taking into account the complementary nature of such information. The method is composed by two basic stages: nitialisation and segmentation. In the first stage, the main contours of the image are used to identify the different regions present in the image and to adequately place a seed for each one in order to statistically model the region. The segmentation stage is performed based on the active region model which allows us to take region and boundary information into account in order to segment the whole image. Furthermore, with the aim of imitating the Human Vision System when a person is slowly approaching to a distant object, a pyramidal structure is considered. Hence, the method has been designed on a pyramidal representation which allows us to refine the region boundaries from a coarse to a fine resolution, and ensuring noise robustness as well as computation efficiency.
