Hard real-time systems are very predictable, but not sufficiently flexible to adapt to dynamic situations. They are built under pessimistic assumptions to cope with worst-case scenarios, so they often waste resources. Soft real-time systems are built to reduce resource consumption, tolerate overloads and adapt to system changes. They are also more suited to novel applications of real-time technology, such as multimedia systems, monitoring apparatuses, telecommunication networks, mobile robotics, virtual reality, and interactive computer games. This unique monograph provides concrete methods for building flexible, predictable soft real-time systems, in order to optimize resources and reduce costs. It is an invaluable reference for developers, as well as researchers and students in Computer Science.
A noir and sensual page-turner that cracks open the Mafia’s secret world through the stories of four lives Palermo in the 1980s is a perfect place for a young crime reporter to get his start. The Sicilian Mafia is at work, threatening, wounding, and killing anyone who dares to defy their orders. Our protagonist is himself no angel, hardly compassionate, a bit macho and egocentric, but candid in his recounting of what has unfolded in front of his eyes both on the job and in his private life. Di Piazza, who is also a Sicilian journalist, tells his stories as if he were reporting actual events. His description of the tense bravado of a youth growing up in the midst of Mafia terror is strikingly acute.
In the Earth Sciences, the concept of fractals and scale invariance is well-recognized in many natural objects. However, the use of fractals for spatial and temporal analyses of natural hazards has been less used (and accepted) in the Earth Sciences. This book brings together twelve contributions that emphasize the role of fractal analyses in natural hazard research, including landslides, wildfires, floods, catastrophic rock fractures and earthquakes. A wide variety of spatial and temporal fractal-related approaches and techniques are applied to 'natural' data, experimental data, and computer simulations. These approaches include probabilistic hazard analysis, cellular-automata models, spatial analyses, temporal variability, prediction, and self-organizing behaviour. The main aims of this volume are to present current research on fractal analyses as applied to natural hazards, and to stimulate the curiosity of advanced Earth Science students and researchers in the use of fractals analyses for the better understanding of natural hazards.
Using the Enel case, this volume unpacks the effective implementation of an ambidextrous perspective on adaptation and change, providing some key lessons for managers and scholars. It begins by exploring Enel's recent history, before mapping the steps of a remarkable transition from public monopolist to a successful transnational group.
Derived from the renowned multi-volume International Encyclopaedia of Laws, this practical analysis of the law of contracts in Italy covers every aspect of the subject - definition and classification of contracts, contractual liability, relation to the law of property, good faith, burden of proof, defects, penalty clauses, arbitration clauses, remedies in case of non-performance, damages, power of attorney, and much more. Lawyers who handle transnational contracts will appreciate the explanation of fundamental differences in terminology, application, and procedure from one legal system to another, as well as the international aspects of contract law. Throughout the book, the treatment emphasizes drafting considerations. An introduction in which contracts are defined and contrasted to torts, quasi-contracts, and property is followed by a discussion of the concepts of ‘consideration’ or ‘cause’ and other underlying principles of the formation of contract. Subsequent chapters cover the doctrines of ‘relative effect’, termination of contract, and remedies for non-performance. The second part of the book, recognizing the need to categorize an agreement as a specific contract in order to determine the rules which apply to it, describes the nature of agency, sale, lease, building contracts, and other types of contract. Facts are presented in such a way that readers who are unfamiliar with specific terms and concepts in varying contexts will fully grasp their meaning and significance. Its succinct yet scholarly nature, as well as the practical quality of the information it provides, make this book a valuable time-saving tool for business and legal professionals alike. Lawyers representing parties with interests in Italy will welcome this very useful guide, and academics and researchers will appreciate its value in the study of comparative contract law.
On The Foundations of Computing is a technical, historical and conceptual investigation in the three main methodological approaches to the computational sciences: mathematical, engineering and experimental. The first part of the volume explores the background behind the formal understanding of computing, originating at the end of the XIX century, and it invesitagtes the formal origins and conceptual development of the notions of computation, algorithm and program. The second part of the volume overviews the construction of physical devices to perform automated tasks and it considers associated technical and conceptual issues. We start from the design and construction of the first generation of computing machines, explore their evolution and progress in engineering (for both hardware and software), and investigate their theoretical and conceptual problems. The third part of the volume analyses the methods and principles of experimental sciences founded on computational methods. We study the use of machines to perform scientific tasks, with particular reference to computer models and simulations. Each part aims at defining a notion of computational validity according to the corresponding methodological approach"--
700 years after Dante Alighieri's death, this book intertwines the voice of the great poet with that of an exceptional contemporary, Marco Polo, who was equally curious about the geography of both earthly and celestial worlds. If Polo was the “ordinary genius” of the XIII century, the designation of “sorcerer genius” must go to Alighieri, the man with encyclopedic wisdom, at ease with his era’s philosophy, theology, and science. The sorcerer genius—well versed in this world—must create their own, which he did with The Divine Comedy. On the other hand, The Travels of Marco Polo, the greatest classic in travel literature, offers wonder and provides delight. This book combines the unforgettable characters of both books, the darkness of the infernal landscapes with the immensity of the Asian deserts, the richness of the Mongol empire with the glamor of medieval philosophy, the aspirations and dreams of two great explorers with knowledge of the science of their time, as well as the ever-eternal cosmology. This is an accessible and entertaining book for high school students, scholars of scientific history and the history of ideas, and curious readers who want to know more about Dante and Marco Polo and their unquenchable thirst for knowledge. This book is a translation of an original Italian edition. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation.
