Pressure vessels are closed containers designed to hold gases or
liquids at a pressure substantially different from the ambient
pressure. They have a variety of applications in industry,
including in oil refineries, nuclear reactors, vehicle airbrake
reservoirs, and more. The pressure differential with such vessels
is dangerous, and due to the risk of accident and fatality around
their use, the design, manufacture, operation and inspection of
pressure vessels is regulated by engineering authorities and guided
by legal codes and standards. "Pressure Vessel Design Manual" is a
solutions-focused guide to the many problems and technical
challenges involved in the design of pressure vessels to match
stringent standards and codes. It brings together otherwise
scattered information and explanations into one easy-to-use
resource to minimize research and take readers from problem to
solution in the most direct manner possible.
Paul Newman wore his Daytona Rolex every single day for 35 years until his death in 2008. The iconic timepiece, probably the single most sought-after watch in the world, is now in the possession of his daughter Clea, who wears it every day in his memory. Franklin Roosevelt wore an elegant gold Tiffany watch, gifted to him by a friend on his birthday, to the famous Yalta Conference where he shook the hands of Joseph Stalin and Winston Churchill. JFK's Omega worn to his presidential inauguration, Ralph Lauren's watch purchased from Andy Warhol's personal collection, Sir Edmund Hillary's Rolex worn during the first-ever summit of Mt. Everest...these and many more compose the stories of the world's most coveted watches captured in A Man and His Watch. Matthew Hranek, a watch collector and NYC men's style fixture, has travelled the world conducting firsthand interviews and diving into exclusive collections to gather the never-before- told stories of 76 watches, complete with stunning original photography of every single piece.
This volume studies, in chronological order, three types of large clocks-wall, cabinet and free-standing, with particular attention to clocks from France, England, Holland, Scandinavia and the German-speaking countries. The emphasis is on French clocks due to recent great interest in the trade of these among collectors. The English clocks, still favored by a large group of collectors, are strongly represented here and there are several beautiful examples from Holland. The German speaking area, including Austria, Germany, and Switzerland are also well represented especially with clocks from south Germany-a delight for lovers and collectors of the Baroque and Rocco clocks. European Pendulum Clocks is essential for the collector of clocks, dealers, auction houses, museums, and anyone awed by the beauty and craftsmanship of these fascinating timepieces.
For Neophytes - to learn the fundamentals, and appreciate the main features of a model, its qualities and weaknesses. For amateurs - to create the desire to know more about fine watches. For connoisseurs - to revise important concepts and even increase their knowledge. This new edition includes new illustrations. What is a beautiful watch? How do you make a good choice? The Magic of Watches explains how and why these little objects are so precious, fascinating and exciting. The book presents paradoxes: why a one-million-dollar watch might be less precise and more fragile than one that costs 15 dollars. It comes back to the origins of the measurement of time: how did we go from the water clock to the wristwatch? The book goes on to technique: how does a mechanical movement work? How does a quartz one work?; delves into details: what is a 'complication' and when do we speak about 'chronometer'?; showcases art: how do we enamel a dial? The Magic of Watches is unique: it focuses in detail on the basics in order to understand and love watches better.
High quality optical components for consumer products made of glass and plastic are mostly fabricated by replication. This highly developed production technology requires several consecutive, well-matched processing steps called a "process chain" covering all steps from mold design, advanced machining and coating of molds, up to the actual replication and final precision measurement of the quality of the optical components. Current market demands for leading edge optical applications require high precision and cost effective parts in large volumes. For meeting these demands it is necessary to develop high quality process chains and moreover, to crosslink all demands and interdependencies within these process chains. The Transregional Collaborative Research Center "Process chains for the replication of complex optical elements" at Bremen, Aachen and Stillwater worked extensively and thoroughly in this field from 2001 to 2012. This volume will present the latest scientific results for the complete process chain giving a profound insight into present-day high-tech production.

During the five hundred years that horology has been accepted as a separate art only a dozen or so men have made a positive contribution to its progress. Included in this little group of masters is the illustrious name of Abraham Louis Breguet (1747-1823), the arch-mecanicien in an age of mechanics. His contribution was as brilliant as it was original and, during a period when horological fashion was the slave of science, he lifted the watchmaker's art to a new dimension of visual and technical excellence. In doing so he radically changed the whole concept of horology and transformed it into an art form that won him the adulation of Europe. The unceasing search for perfection in the performance of his products led Breguet to the invention of mechanical principles that even today, are used in the design of the watch. His influence on the appearance and style of the watch was dramatic and his most complicated examples maintained the slim, elegant appearance that was to revolutionise watchmaking. Breguet's extraordinary ability in all branches of horology achieved for him the reputation of a genius, the patronage of kings and - rarest of all - the respect of the horological world. His products have never lost favour and many, in constant use, have been handed down through generations to their present owners. The passing of the years, with their many changes of fashion, have not diminished the beauty of the proportions and appearance of Breguet's work. The Art of Breguet is the complete, illustrated history of the work of Abraham Louis Breguet by the late George Daniels who has provided a detailed study of Breguet's horological philosophy that explains so many of the misunderstood aspects of his work. He describes in detail the complexity of Breguet's art and, by so doing, supplants the mystique that has surrounded it with a clearer understanding of its function. Over one hundred line drawings illustrate the progress of technical development and each is accompanied by an analysis of the mechanism and its intended purpose. The history of the development of the internal and external appearance of the vast range of Breguet's products is illustrated in a separate section, arranged in the order of manufacture to reveal the pattern of change in appearance. Each item is accompanied by a description of its external characteristics, mechanism, period of manufacture and, where possible, the date of sale. This reprinted edition, with a foreword by Emmanuel Breguet, has been long awaited and is addressed equally to the student and to the collector of Breguet's work.
This book describes the construction of two different clock projects - an eight day regulator clock and a month going regulator clock - and features full-page fully-dimensionalised working drawings supported by detailed photographs. It also includes instructions and plans for constructing glazed wood cases for each project. It is intended for model engineering hobbyists with basic facilities to enable them to venture into the field of horology by building their own precision clocks which can become treasured family heirlooms. The term 'regulator' simply describes a precision clock. Every clockmaker and repairer needs such an instrument to use in regulating his repair and new work. The typical English regulator, as described in the first section, beats at one second intervals and will run for eight days between winding. The second project is a month going regulator clock, an equally high precision type which will run for a whole month between winding. This book is based on a popular series of popular articles originally published over many years in Model Engineer magazine.

This is a textbook for graduate and final-year-undergraduate computer-science and electrical-engineering students interested in the hardware and software aspects of embedded and cyberphysical systems design. It is comprehensive and self-contained, covering everything from the basics to case-study implementation. Emphasis is placed on the physical nature of the problem domain and of the devices used. The reader is assumed to be familiar on a theoretical level with mathematical tools like ordinary differential equation and Fourier transforms. In this book these tools will be put to practical use. Engineering Embedded Systems begins by addressing basic material on signals and systems, before introducing to electronics. Treatment of digital electronics accentuating synchronous circuits and including high-speed effects proceeds to micro-controllers, digital signal processors and programmable logic. Peripheral units and decentralized networks are given due weight. The properties of analog circuits and devices like filters and data converters are covered to the extent desirable by a systems architect. The handling of individual elements concludes with power supplies including regulators and converters. The final section of the text is composed of four case studies: * electric-drive control, permanent magnet synchronous motors in particular; * lock-in amplification with measurement circuits for weight and torque, and moisture; * design of a simple continuous wave radar that can be operated to measure speed and distance; and * design of a Fourier transform infrared spectrometer for process applications. End-of-chapter exercises will assist the student to assimilate the tutorial material and these are supplemented by a downloadable solutions manual for instructors. The "pen-and-paper" problems are further augmented with laboratory activities. In addition to its student market, Engineering Embedded Systems will assist industrial practitioners working in systems architecture and the design of electronic measurement systems to keep up to date with developments in embedded systems through self study.

This book provides a comprehensive introduction to ferroics and frustrated materials. Ferroics comprise a range of materials classes with functionalities such as magnetism, polarization, and orbital degrees of freedom and strain. Frustration, due to geometrical constraints, and disorder, due to chemical and/or structural inhomogeneities, can lead to glassy behavior, which has either been directly observed or inferred in a range of materials classes from model systems such as artificial spin ice, shape memory alloys, and ferroelectrics to electronically functional materials such as manganites. Interesting and unusual properties are found to be associated with these glasses and have potential for novel applications. Just as in prototypical spin glass and structural glasses, the elements of frustration and disorder lead to non-ergodocity, history dependence, frequency dependent relaxation behavior, and the presence of inhomogeneous nano clusters or domains. In addition, there are new states of matter, such as spin ice; however, it is still an open question as to whether these systems belong to the same family or universality class. The purpose of this work is to collect in a single volume the range of materials systems with differing functionalities that show many of the common characteristics of geometrical frustration, where interacting degrees of freedom do not fit in a lattice or medium, and glassy behavior is accompanied by additional presence of disorder. The chapters are written by experts in their fields and span experiment and theory, as well as simulations. Frustrated Materials and Ferroic Glasses will be of interest to a wide range of readers in condensed matter physics and materials science.

Metallic quantum clusters belonging to intermediate size regime between two and few hundred of atoms, represent unique building blocks of new materials. Nonlinear optical (NLO) characteristics of liganded silver and gold quantum clusters reveal remarkable features which can be tuned by size, structure and composition. The two-photon absorption cross sections of liganded noble metal quantum clusters are several orders of magnitude larger than that of commercially-available dyes. Therefore, the fundamental photophysical understanding of those two-photon processes in liganded clusters with few metal atoms deserve special attention, in particularly in context of finding the mechanisms responsible for these properties. A broad range of state-of-the-art experimental methods to determine nonlinear optical properties (i.e. two-photon absorption, two-photon excited fluorescence and second harmonic generation) of quantum clusters are presented. The experimental setup and underlying physical concepts are described. Furthermore, the theoretical models and corresponding approaches are used allowing to explain the experimental observations and simultaneously offering the possibility to deduce the key factors necessary to design new classes of nanoclusters with large NLO properties. Additionally, selected studied cases of liganded silver and gold quantum clusters with focus on their NLO properties will be presented as promising candidates for applications in imaging techniques such as fluorescence microscopy or Second-Harmonic Generation microscopy.
This book highlights what is now achievable in terms of materials characterization with the new generation of cold-field emission scanning electron microscopes applied to real materials at high spatial resolution. It discusses advanced scanning electron microscopes/scanning- transmission electron microscopes (SEM/STEM), simulation and post-processing techniques at high spatial resolution in the fields of nanomaterials, metallurgy, geology, and more. These microscopes now offer improved performance at very low landing voltage and high -beam probe current stability, combined with a routine transmission mode capability that can compete with the (scanning-) transmission electron microscopes (STEM/-TEM) historically run at higher beam accelerating voltage
In this book the coherent quantum transport of electrons through two-dimensional mesoscopic structures is explored in dependence of the interplay between the confining geometry and the impact of applied magnetic fields, aiming at conductance controllability. After a top-down, insightful presentation of the elements of mesoscopic devices and transport theory, a computational technique which treats multiterminal structures of arbitrary geometry and topology is developed. The method relies on the modular assembly of the electronic propagators of subsystems which are inter- or intra-connected providing large flexibility in system setups combined with high computational efficiency. Conductance control is first demonstrated for elongated quantum billiards and arrays thereof where a weak magnetic field tunes the current by phase modulation of interfering lead-coupled states geometrically separated from confined states. Soft-wall potentials are then employed for efficient and robust conductance switching by isolating energy persistent, collimated or magnetically deflected electron paths from Fano resonances. In a multiterminal configuration, the guiding and focusing property of curved boundary sections enables magnetically controlled directional transport with input electron waves flowing exclusively to selected outputs. Together with a comprehensive analysis of characteristic transport features and spatial distributions of scattering states, the results demonstrate the geometrically assisted design of magnetoconductance control elements in the linear response regime.
