Storia urbana del palazzo della Ragione di Padova in relazione all'evoluzione della città dal XIII secolo ai giorni nostri. Attraverso 31 tavole si analizza la funzione e la concezione del palazzo non come manufatto artistico ma come macchina tecnologica, un perfetto ingranaggio pensato per far funzionare la complessa meccanica urbana della città fatta di strade, edifici, attività economiche e vita sociale.
This invaluable book provides a broad and comprehensive introduction to the fascinating and beautiful subject of timeless approaches in physics, focusing the attention in particular on significant models developed recently by the author. It presents relevant and novel perspectives in 21st century theoretical physics as regards the arena of physical processes and its geometry (both in special relativity, quantum mechanics, the quantum gravity domain and about the quantum vacuum). The timeless approach may be used as a source of reference by researchers in theoretical physics and at the same time it is also suitable for graduate students in physics who wish to have an extend view of some of the classic and fundamental models in the subject.
How digital technology--from Facebook tributes to QR codes on headstones--is changing our relationship to death. Facebook is the biggest cemetery in the world, with countless acres of cyberspace occupied by snapshots, videos, thoughts, and memories of people who have shared their last status updates. Modern society usually hides death from sight, as if it were a character flaw and not an ineluctable fact. But on Facebook and elsewhere on the internet, we can't avoid death; digital ghosts--electronic traces of the dead--appear at our click or touch. On the Internet at least, death has once again become a topic for public discourse. In Online Afterlives, Davide Sisto considers how digital technology is changing our relationship to death.
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
The book provides a comprehensive description of the basic ultrasound principles, normal anatomy of the lower limb muscles and classification of muscle strain injuries. Ultrasound images are coupled with anatomical schemes explaining probe positioning and scanning technique for the various muscles of the thigh and leg. For each muscle, a brief explanation of normal anatomy is also provided, together with a list of tricks and tips and advice on how to perform the ultrasound scan in clinical practice. This book is an excellent practical teaching guide for beginners and a useful reference for more experienced sonographers.
