In these exciting times of quotidianly progressing developments in communication techniques, where more than ever in the history of a technological progress, society's reliance on communication networks for medicine, education, data transfer, commerce, and many other endeavours dominates the human's everyday life, the optical networks are certainly one of the most promising and challenging networking options. Since their commercial arrival in the nineties, they have fundamentally changed the way of dealing with traffic engineering by removing bandwidth bottlenecks and eliminating delays. Today, after the revolutionary bandwidth expansion, the networking functionality migrates more and more to the optical layer, and the need to establish fast wavelength circuits and capacity-on-demand for the higher-layer networks, in particular data networks based on Internet Protocol (IP), has become one of the central networking issues for the new century. The unifying trends toward configurable all-optical network infrastructure open up a wide range of new network engineering and design choices dealing with networks' interoperability and common platforms for control and management. The Fifth Working Conference on optical Network design and Modelling, held in the Austrian capital vienna, February 5-7, 2001, aims at presenting the most recent progress in optical communication techniques, new technologies, standardisation process, emerging markets and carriers. A short look at the Table of Contents of this book tells us, in fact, that this year's conference program reflects the current state of the art precisely.

Dr. C. v. Drysdale, C.B., C.B.E.

引用

Nature 1936年第3459期137卷 266-266页

THE thirteenth Duddell Medal of the Physical Society was presented on February 7 to Dr. C. v. Drysdale, who is distinguished for his outstanding work in connexion with electrical and optical instruments. Dr. Drysdale was responsible for the design of the first accurate single-phase standard wattmeters in 1901, following them immediately by the first double wattmeters for polyphase measurements, and a few years later by accurate phase-shifting transformers for wattmeter and supply meter testing. In 1909 he adapted the phase-shifting transformer to the design of the first alternating and direct current potentiometer, and devised a vibration galvanometer and low inductance resistance standards which enables that instrument to be used for standardising purposes as well as for general testing, applying it particularly to transmission in telephone circuits. He was also responsible for other electrical standardising apparatus. In 1899, he took charge of the Electrical engineering and Applied Physics Department of the Northampton Institute, Clerkenwell, and in the following year started the first Technical Optics Department at the Northampton Institute, with a lens grinding workshop. Then came a period of active research in optics, and including the design of lens systems, a universal optical bench for the rapid testing of spherical and cylindrical lens, etc.

As we approach the end of the present century, the elementary particles of light (photons) are seen to be competing increasingly with the elementary particles of charge (electrons/holes) in the task of transmitting and processing the insatiable amounts of infonnation needed by society. The massive enhancements in electronic signal processing that have taken place since the discovery of the transistor, elegantly demonstrate how we have learned to make use of the strong interactions that exist between assemblages of electrons and holes, disposed in suitably designed geometries, and replicated on an increasingly fine scale. On the other hand, photons interact extremely weakly amongst themselves and all-photonic active circuit elements, where photons control photons, are presently very difficult to realise, particularly in small volumes. Fortunately rapid developments in the design and understanding of semiconductor injection lasers coupled with newly recognized quantum phenomena, that arise when device dimensions become comparable with electronic wavelengths, have clearly demonstrated how efficient and fast the interaction between electrons and photons can be. This latter situation has therefore provided a strong incentive to devise and study monolithic integrated circuits which involve both electrons and photons in their operation. As chapter I notes, it is barely fifteen years ago since the first demonstration of simple optoelectronic integrated circuits were realised using m-v compound semiconductors; these combined either a laser/driver or photodetector/preamplifier combination.

Building Information Modeling (BIM) refers to the consistent and continuous use of digital information throughout the entire lifecycle of a built facility, including its design, construction and operation. In order to exploit BIM methods to their full potential, a fundamental grasp of their key principles and applications is essential. Accordingly, this book combines discussions of theoretical foundations with reports from the industry on currently applied best practices.;The book’s content is divided into six parts: Part I discusses the technological basics of BIM and addresses computational methods for the geometric and semantic modeling of buildings, as well as methods for process modeling. Next, Part II covers the important aspect of the interoperability of BIM software products and describes in detail the standardized data format Industry Foundation Classes. It presents the different classification systems, discusses the data format CityGML for describing 3D city models and COBie for handing over data to clients, and also provides an overview of BIM programming tools and interfaces. Part III is dedicated to the philosophy, organization and technical implementation of BIM-based collaboration, and discusses the impact on legal issues including construction contracts. In turn, Part Iv covers a wide range of BIM use cases in the different lifecycle phases of a built facility, including the use of BIM for design coordination, structural analysis, energy analysis, code compliance checking, quantity take-off, prefabrication, progress monitoring and operation. In Part v, a number of design and construction companies report on the current state of BIM adoption in connection with actual BIM projects, and discuss the approach pursued for the shift toward BIM, including the hurdles taken. Lastly, Part vI summarizes the book’s content and provides an outlook on future developments.;The book was written both for professionals using or programming such tools, and for students

This volume contains papers that were presented at the NATO Advanced Research Workshop on Nanostructured Materials and Coatings for Biomedical and Sensor Applications held in Kyiv, Ukraine, 4-8 August, 2002. A total of 104 scientists from 14 countries participated in our ARW, making it a really international event. Participants ranged from graduate students to senior researchers. They presented 16 tutorial lectures, 20 short talks and more than 70 posters. Invited speakers, from NATO and Partner countries, presented some of the most recent developments in physics, chemistry and technology of nanosized materials. A broad range of speakers having international standing and representing NATO and partner countries, as well as university, industrial and govemment research laboratories participated in this meeting and wrote papers for this volume. Foregoing ARW gathered together the scientists working in the area of nanosized materials and coatings and their applications in biomedicine and sensors. The first objective of this AR W was to discuss the current research covering a wide range of physical and chemical properties of biomaterials and their use. Active discussion of oral presentations and posters, and the round table discussion gave a good opportunity to researchers from academia and industry to discuss the achievements in this field and outline future directions in terms of technological developments and product commercialisation in the fields of biomedicine and sensors. Particularly, advanced ceramics and nanostructured carbons were covered in many presentations.

Fuse cut-outs — Their design and application for A-C. distribution circuits

引用

Electrical engineering 1931年第11期50卷 903-903页

作者： E. G. Newton General Electric Co. Pittsfield Mass.

MANY NEW developments to meet modern requirements have been applied to the renewable expulsion-fuse and oil-fuse cut-outs for a-c. distribution systems of 15,000 volts and below. While there are several different types of fuse cut-outs, the universal design problem is the interruption of an arc formed when the current carrying element melts. Both expulsion-fuse and oil-fuse cut-outs depend for this interruption upon the gas pressure generated by the current in the arc.

A Wide-Band Inductive-Output Amplifier

引用

Proceedings of the IRE 1940年第3期28卷 126-130页

作者： Dhaeff, Andrew v. Nergaard, Leon S. Research and Engineering Department RCA Manufacturing Co. Inc. Harrison N.J. United States

In order to obtain amplification over a wide band of frequencies, a tube having high transconductance and low input and output capacitance is required. A grid-controlled inductive-output tube-having these attributes and giving 10 watts output at 500 megacycles is described. A high ratio of transconductance to input capacitance is attained by close cathode-grid spacing and large grid-screen spacing, the latter made possible by use of a very high screen voltage. A low output capacitance is obtained by the use of an inductive-output arrangement which requires no power dissipation by the output electrodes. The design of the output circuit for low inherent capacitance is facilitated by the use of magnetic lenses to focus the electron beam. These lenses can be energized by a permanent magnet. Loading caused by secondary electron emission from the current collector is eliminated. The performance of the tube as a wide-band amplifier is described.

Fundamentals of optical Fiber Sensor Technology The field of optical fiber sensors continues to expand and develop, being increasingly influenced by new applications of the technologies that have been the topics of research for some years. In this way, the subject continues to mature and reach into new areas of engineering. This text in the series on optical Fiber Sensor Technology provides a foundation for a better understanding of those developments in the basic science and its applications in fiber sensors, underpinning the subject today. This book builds upon the work in an earlier single volume which covered a broad area of the subject, but which now, in this, volume 1 of the series, focuses upon the fundamentals and essentials of the technology. Material which is included has been carefully reviewed and in most cases thoroughly revised and expanded to reflect the current state of the subject, and provide an essential background for the more applications-oriented content of the subsequent volumes of the series. This volume opens with a status paper on optical fiber sensor technology, by Kenneth Grattan and Tong Sun providing in it a flavor of the main topics in the field and giving an essential overview at the sort of systems which are discussed in more detail in the other chapters in the whole series. An extensive publication list of readily accessible papers reflecting these topics is included.
