A groundbreaking study of the development of mechanical and metal cased pencils in the nineteenth century. Illustrated with over 700 photographs, the book provides examples of the extraordinary variety of propelling pencils that were created between 1800 and 1920. Readers will be struck by the ingenuity of the inventors and creators of this (until now) forgotten form of decorative art. From metal cased pencils that are elegantly practical, to "magic" pencils that are more whimsical than functional, this book follows the progress of the mechanical pencil as it evolves from a usable tool to something more akin to jewelry. This history of mechanical pencils also includes definitions of terms, descriptions of various mechanisms, ornamentation and surface decoration, and the multitude of combinations created by nineteenth century pencil-case makers. Value ranges are also included.

The thesis tackles one of the most difficult problems of modern nanoscale science and technology - exploring what governs thermal phenomena at the nanoscale, how to measure the temperatures in devices just a few atoms across, and how to manage heat transport on these length scales. Nanoscale heat generated in microprocessor components of only a few tens of nanometres across cannot be effectively fed away, thus stalling the famous Moore's law of increasing computer speed, valid now for more than a decade. In this thesis, Jean Spiece develops a novel comprehensive experimental and analytical framework for high precision measurement of heat flows at the nanoscale using advanced scanning thermal microscopy (SThM) operating in ambient and vacuum environment, and reports the world's first operation of cryogenic SThM. He applies the methodology described in the thesis to novel carbon-nanotube-based effective heat conductors, uncovers new phenomena of thermal transport in two- dimensional (2D) materials such as graphene and boron nitride, thereby discovering an entirely new paradigm of thermoelectric cooling and energy production using geometrical modification of 2D materials.

Due to their speed, data density, and versatility, optical metrology tools play important roles in today s high-speed industrial manufacturing applications. Handbook of Optical Dimensional Metrology provides useful background information and practical examples to help readers understand and effectively use state-of-the-art optical metrology methods.

The book first builds a foundation for evaluating optical measurement methods. It explores the many terms of optical metrology and compares it to other forms of metrology, such as mechanical gaging, highlighting the limitations and errors associated with each mode of measurement at a general level. This comparison is particularly helpful to current industry users who operate the most widely applied mechanical tools.

The book then focuses on each application area of measurement, working down from large area to medium-sized to submicron measurements. It describes the measurement of large objects on the scale of buildings, the measurement of durable manufactured goods such as aircraft engines and appliances, and the measurement of fine features on the micron and nanometer scales. In each area, the book covers fast, coarse measures as well as the finest measurements possible. Best practices and practical examples for each technology aid readers in effectively using the methods.

Requiring no prior expertise in optical dimensional metrology, this handbook helps engineers and quality specialists understand the capabilities and limitations of optical metrology methods. It also shows them how to successfully apply optical metrology to a vast array of current engineering and scientific problems.

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.

Jesse Ramsden was one of the most prominent manufacturers of scientific instruments in the latter half of the eighteenth century. To own a Ramsden instrument, be it one of his great theodolites or one of the many sextants and barometers produced at his London workshop, was to own not only an instrument of incredible accuracy and great practical use, but also a thing of beauty. In this, the first biography of Jesse Ramsden, Dr Anita McConnell reconstructs his life and career and presents us with a detailed account of the instrument trade in this period. By studying the life of one prominent instrument maker, the entire practice of the trade is illuminated, from the initial commission, the intricate planning and design, through the practicalities of production, delivery and, crucially, payment for the work. The book will naturally be of immeasurable interest to historians of science and scientific instruments but, as it also sheds light on the increasing commercialisation of the scientific trade on the cusp of the Industrial Revolution, should also interest social and economic historians of the eighteenth century.

At the start of the Industrial Revolution, it appeared that most scientific instruments were made and sold in London, but by the time of the Great Exhibition in 1851, a number of provincial firms had the self-confidence to exhibit their products in London to an international audience. How had this change come about, and why? This book looks at the four main, and two lesser, English centres known for instrument production outside the capital: Birmingham, Liverpool, Manchester and Sheffield, along with the older population centres in Bristol and York. Making wide use of new sources, Dr Morrison-Low, curator of history of science at the National Museums of Scotland, charts the growth of these centres and provides a characterisation of their products. New information is provided on aspects of the trade, especially marketing techniques, sources of materials, tools and customer relationships. From contemporary evidence, she argues that the principal output of the provincial trade (with some notable exceptions) must have been into the London marketplace, anonymously, and at the cheaper end of the market.She also discusses the structure and organisation of the provincial trade, and looks at the impact of new technology imported from other closely-allied trades. By virtue of its approach and subject matter, the book considers aspects of economic and business history, gender and the family, the history of science and technology, material culture, and patterns of migration. It contains a myriad of stories of families and firms, of entrepreneurs and customers, and of organizations and arms of government. In bringing together this wide range of interests, Dr Morrison-Low enables us to appreciate how central the making, selling and distribution of scientific instruments was for the Industrial Revolution.

This expert volume provides specialized coverage of the current state of the art in carbon gels. Carbon gels represent a promising class of materials with high added value applications and many assets, like the ability to accurately tailor their structure, porosity, and surface composition and easily dope them with numerous species. The ability to obtain them in custom shapes, such as powder, beads, monoliths, or impregnated scaffolds opens the way towards numerous applications, including catalysis, adsorption, and electrochemical energy storage, among others. Nevertheless, it remains a crucial question as to which design synthesis and manufacturing processes are viable from an economic and environmental point of view. The book represents the perspectives of renowned specialists in the field, specially invited to conduct a one-day workshop devoted to carbon gels as part of the 19th International Sol-Gel Conference, SOL-GEL 2017, held on September 3rd, 2017 in Liege, Belgium. Addressing properties and synthesis through applications and industry outlook, this book represents essential reading for advanced graduate students through practicing researchers interested in these exciting materials.

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 develops the analytical theory of perfectly conducting and lossy metal, circular, round-wire loop antennas and nano-scaled rings from the radio frequency (RF) regime through infrared and the optical region. It does so from an antenna theory perspective. It is the first time that all of the historical material found in the literature has appeared in one place. It includes, particularly, material that has appeared in the literature only in the last decade and some new material that has not yet been published. The book derives the input impedance, resonances and anti-resonances, the RLC circuit model representation, and radiation patterns not only of closed loops and rings, but also of loops and rings loaded randomly and multiply with resistive and reactive impedances. Every derivation is compared with simulations run in Microwave Studio (MWS). It looks carefully at the physical response of loop antennas and nano-rings coupled to a source at one point in the periphery and at such rings illuminated by a plane wave arriving from every different direction with the E-field in all polarizations. The book ends with a brief look at polygonal loops, two dimensional arrays of nano-rings, and Yagi-Uda arrays.

From the Author's Preface
Ceramic sensors have been in use for more than thirty years. Since ceramics exhibit a number of specific characteristics that enable their cost to become lower and their reliability to increase, they have occupied a significant position in sensor technology. This is why many companies and universities have directed their efforts towards investigating and developing new ceramic sensors and expanding their areas of application.
To the best of our knowledge.., there has been] no book treating different sensors on the basis of their common physical and chemical properties, technological principles, and applications. This book is] a detailed survey of ceramic sensors and a generalization of the results achieved in this field so far. Ceramic sensors for different physical quantities are discussed without going too deep into theory...
The concept of ceramic sensors includes all sensors that are produced using ceramic technology. It also covers thick film sensors, since from a structural and technological point of view, they can be regarded as a variety of ceramic sensors. The subject of scientific research in this book is humidity, gas. temperature, and pressure sensors on the basis of semiconductor and dielectric ceramic materials and solid electrolytes.
Special attention is paid to the physical and chemical, as well as the technological, bases of ceramic sensors, their classification, the types of materials used..., the methods of controlling their parameters and characteristics, the areas of application, and the electric circuits for connecting the sensors.

Polymer films now play an essential and growing role in sensors.

This new book is the first comprehensive presentation of this technology. It covers both scientific fundamentals and practical engineering aspects. Included is an extensive survey of all types of sensors and applications. The very detailed table of contents in the next pages provides full information on content. More than 200 schematics illustrate a wide variety of sensor structures and their function.

Inelastic media constitute a rich source of interesting and important problems in theoretical, experimental and computationalmechanics. Signi?cantinsightshavebeengainedthroughstudiesofthemathematicalchar- teristics of new models. New constitutive theories have lead to variational and other formulations that are generally more complex, often highly nonlinear, and requ- ing new tools for their successful resolution. Likewise, there have been signi?cant advances of a computational nature, coupled to the development of new algorithms for solving such problems in discrete form. It is clear, therefore, that research in the broad area of inelastic media offers c- temporary investigators a range of challenges which are most fruitfully addressed througha combinationof theoretical, experimentaland computationalavenues.F- thermore, the ?eld is truly multidisciplinary in nature, drawing on the expertise of specialists in materials science, various branches of engineering, mathematics, and physics, and bene?ting from integrative approaches to the solution of problems. The objective of the IUTAM Symposium on Theoretical, Modelling and C- putational Aspects of Inelastic Media, held in Cape Town over the period 14-18 January 2008, was to provide a forum in which experts engaged in a spectrum of activities underthe theme of inelastic media could discussrecent developments, and also identify key open problem
