This book presents a simple, yet complete, approach to the design and performance analysis of distributed processing algorithms and techniques suitable for IEEE 802.15.4 networks. In particular, the book focuses on the bottom two layers of the ISO/OSI stack (Physical and Medium Access Control), discussing also a few issue related to routing. The book is a the synergistic combination of signal processing aspects on the one hand and MAC and connectivity issues on the other hand. The goal of the book is to clearly link physical layer aspects with medium access and topology aspects, in order to provide the reader with a clear understanding of how to approach the design of proper distributed signal processing and medium access algorithms in this context.
When choosing the technology options to develop a wireless sensor network (WSN), it is vital that their performance levels can be assessed for the type of application intended. This book describes the different technology options – MAC protocols, routing protocols, localisation and data fusion techniques – and provides the means to numerically measure their performance, whether by simulation, mathematical models or experimental test beds. Case studies, based on the authors' direct experience of implementing wireless sensor networks, describe the design methodology and the type of measurements used, together with samples of the performance measurements attained. Wireless Sensor and Actuator Networks will enable you to answer vital questions such as: - How long will my network remain alive given the amount of sensing required of it? - For how long should I set the sleeping state of my motes? - How many sensors should I distribute to meet the expected requirements of the application? - What type of throughput should I expect as a function of the number of nodes deployed and the radio interface chosen (whether it be Bluetooth or Zigbee)? - How is the Packet Error Rate of my Zigbee motes affected by the selection of adjacent frequency sub bands in the ISM 2.4GHz band? - How is the localisation precision dependant on the number of nodes deployed in a corridor? Communications and signal processing engineers, researchers and graduate students working in wireless sensor networks will find this book an invaluable practical guide to this important technology. "This book gives a proper balance between theory and application; it is a book for those R&D engineers that want to appreciate both why, how and in which domains Wireless Sensor Networks can be best applied." --Fabio Bellifemine, Telecom Italia "This book is a thorough and accessible exposition on wireless sensor networks with a good balance between theory and practice; it is valuable for both students and practicing engineers, and is an essential addition for engineering libraries." --Professor Moe Win, Associate Professor at the Laboratory for Information and Decision Systems (LIDS), Massachusetts Institute of Technology - Only book to examine wireless sensor network technologies and assess their performance capabilities against possible applications - Enables the engineer to choose the technology that will give the best performance for the intended application - Case studies, based on the authors' direct experience of implementing wireless sensor networks, describe the design methodology and the type of measurements used, together with samples of the performance measurements attained
Elio Petri (1929-1982) was one of the most commercially successful and critically revered Italian directors ever. A cultured intellectual and a politically committed filmmaker, Petri made award-winning movies that touched controversial social, religious, and political themes, such as the Mafia in We Still Kill the Old Way (1967), police brutality in Investigation of a Citizen Above Suspicion (1970), and workers' struggles in Lulu the Tool (1971). His work also explored genre in a thought-provoking and refreshing manner with a taste for irony and the grotesque: among his best works are the science fiction satire The 10th Victim (1965), the ghost story A Quiet Place in the Country (1968), and the grotesque giallo Todo modo (1976). This book examines Elio Petri's life and career, and places his work within the social and political context of postwar Italian culture, politics, and cinema. It includes a detailed production history and critical analysis of each of his films, plenty of never-before-seen bits of information recovered from the Italian ministerial archives, and an in-depth discussion of the director's unfilmed projects.
Tonino Valerii is one of Italy's best genre film directors. Starting out as Sergio Leone's assistant on For a Few Dollars More (1965), he went on to direct spaghetti westerns that stand out among the most accomplished in their class--Day of Anger (1967), The Price of Power (1969), A Reason to Live, a Reason to Die! (1972) and My Name Is Nobody (1973). He also directed the outstanding giallo My Dear Killer (1972). This book examines Valerii's life and career in depth for the first time, with exclusive interviews with the filmmaker, scriptwriters and actors, and critical analysis of his films.
The Italian Gothic horror genre underwent many changes in the 1980s, with masters such as Mario Bava and Riccardo Freda dying or retiring and young filmmakers such as Lamberto Bava (Macabro, Demons) and Michele Soavi (The Church) surfacing. Horror films proved commercially successful in the first half of the decade thanks to Dario Argento (both as director and producer) and Lucio Fulci, but the rise of made-for-TV products has resulted in the gradual disappearance of genre products from the big screen. This book examines all the Italian Gothic films of the 1980s. It includes previously unpublished trivia and production data taken from official archive papers, original scripts and interviews with filmmakers, actors and scriptwriters. The entries include a complete cast and crew list, plot summary, production history and analysis. Two appendices list direct-to-video releases and made-for-TV films.
This volume opens up new perspectives on the physics of the Earth’s interior and planetary bodies for graduate students and researchers working in the fields of geophysics, planetary sciences and geodesy. It looks at our planet in an integrated fashion, linking the physics of its interior to geophysical and geodetic techniques that record, over a broad spectrum of spatial wavelengths and time scales, the ongoing modifications in the shape and gravity field of the planet. Basic issues related to the rheological properties of the Earth and to its slow deformation are considered, in both mathematical and physical terms, within the framework of an analytical relaxation theory. Fundamentals of this theory are developed in the first two Chapters. Chapters 3-9 deal with a wide range of applications, ranging from changes in the Earth’s rotation to post-seismic deformation and from sea-level variations induced by post-glacial rebound to tidal deformation of icy moons of the Solar System. This Second Edition improves substantially our formalism implementing compressibility in viscoelastic relaxation. Chapter 5 now contains new developments in the physics of the gravitational effects of large earthquakes at subduction zones, made possible by new gravity data from space missions. The new Chapter 9 of this Second Edition on deformation and stresses of icy moons enlarges the applications of the book to Planetology, dealing with the additional complications in the theory of viscoelastic relaxation introduced by the shallow low-viscosity zones and inviscid water layers of the moons of Jupiter and Saturn.
This volume opens up new perspectives on the physics of the Earth's interior for graduate students and researchers working in the fields of geophysics and geodesy. It looks at our planet in an integrated fashion, linking the physics of its interior to the geophysical and geodetic techniques that record, over a broad spectrum of spatial wavelengths, the ongoing modifications in the shape and gravity field of the planet. Basic issues related to the rheological properties of the Earth's mantle and to its slow deformation will be understood, in both mathematical and physical terms, within the framework of an analytical normal mode relaxation theory. Fundamentals of this theory are developed in the first, tutorial part. The second part deals with a wide range of applications, ranging from changes in the Earth's rotation to post-seismic deformation and sea-level variations induced by post-glacial rebound. In the study of the physics of the Earth's interior, the book bridges the gap between seismology and geodynamics.
The "Gothic" style was a key trend in Italian cinema of the 1950s and 1960s because of its peculiar, often strikingly original approach to the horror genre. These films portrayed Gothic staples in a stylish and idiosyncratic way, and took a daring approach to the supernatural and to eroticism, with the presence of menacing yet seductive female witches, vampires and ghosts. Thanks to such filmmakers as Mario Bava (Black Sunday), Riccardo Freda (The Horrible Dr. Hichcock), and Antonio Margheriti (Castle of Blood), as well the iconic presence of actress Barbara Steele, Italian Gothic horror went overseas and reached cult status. The book examines the Italian Gothic horror of the period, with an abundance of previously unpublished production information drawn from official papers and original scripts. Entries include a complete cast and crew list, home video releases, plot summary and the author's analysis. Excerpts from interviews with filmmakers, scriptwriters and actors are included. The foreword is by film director and scriptwriter Ernesto Gastaldi.
In 1970s Italy, after the decline of the Spaghetti Western, crime films became the most popular, profitable and controversial genre. In a country plagued with violence, political tensions and armed struggle, these films managed to capture the anxiety and anger of the times in their tales of tough cops, ruthless criminals and urban paranoia. Recent years have seen renewed critical interest in the genre, thanks in part to such illustrious fans as Quentin Tarantino. This book examines all of the 220+ crime films produced in Italy between 1968 and 1980, the period when the genre first appeared and grew to its peak. Entries include a complete cast and crew list, home video releases, a plot summary and the author's own analysis. Excerpts from a variety of sources are included: academic texts, contemporary reviews, and interviews with filmmakers, scriptwriters and actors. There are many onset stills and film posters.
