  • This edition of Acetaria is a faithful reprint of the First Edition of 1699, with the correction of a few obvious typographical errors, and those noted in the Errata of the original edition. Whereas no attempt has been made to reproduce the typography of the original, the spirit has been retained, and the vagaries of spelling and punctuation have been carefully followed; also the old-style S [s] has been retained. Much of the flavour of Acetaria is lost if it is scanned too hurriedly; and one should remember also that Latin and Greek were the gauge of a man of letters, and if the titles...

  • Our primary objective herein is not to determine how approximate calculations introduce errors into situations with accurate hypotheses, but instead to study how rigorous calculations transmit errors due to inaccurate parameters or hypotheses. Unlike quantities represented by entire numbers, the continuous quantities generated from physics, economics or engineering sciences, as represented by one or several real numbers, are compromised by errors.

  • Since its first demonstration in 1960, the laser has found widespread application in diverse areas including medicine, materials processing, optical communications and information technology. The number of engineers and scientists working on lasers or in laser related fields is continuously increasing as new applications for this exciting technology are being discovered. This also means that more and more people need to gain a detailed knowledge of lasers and their characteristics.

  • Our analysis will emphasize a mechanism of propagation of the effects of cloud computing which depends on the endogenous market structures. Through business creation, the adoption of cloud computing is going to enhance competition in each sector and to increase production and lower mark ups. This will have a positive im- pact on consumption so as to contribute to the recovery of the EU economy. Most of all, part of these effects are going to be positively related to the speed of adop- tion of the new technology.

  • There are many classes of green bonds that have been issued or proposed, and they have taken on a confusing plethora of names such as green gilts, green retail bonds, green investment bank bonds, green infrastructure bonds, 46 multilateral development bank green bonds, green corporate bonds, green sectoral bonds, rainforest bonds and index-linked carbon bonds. One class of green bonds that has attracted attention recently is the climate bond, which is a type of green bond issued to raise capital for investments in projects which specifically mitigate or adapt to climate change.

  • We have known the close connection between changing eletric fields and magnetic fields. They can create each other and form a system of electromagnetic fields.  Electromagnetic fields can propagate in the space (vacuum or material environment). We call them electromagnetic waves. They play a very important role in science and technology.

  • This volume, derived from the Handbook of Engineering Electromagnetics (2004), is intended as a desk reference for the fundamentals of engineering electromagnetics. Because electromagnetics provides the underpinnings for many technological fields such as wireless communications, fiber optics, microwave engineering, radar, electromagnetic compatibility, material science, and biomedicine, there is a great deal of interest and need for training in the concepts of engineering electromagnetics.

  • This book is intended for courses at least at Masters level to provide an introduction to the field of signal processing in telecommunications. The text therefore deals mainly with source coding, channel coding, modulation and demodulation. Adaptive channel equalisation, the signal processing aspects of adaptive antennas as well as multi-user detectors for CDMA are also included. Shorter sections on link budget, synchronising and cryptography are also included. Network aspects are not discussed and very little is given about wave propagation.

  • “Diffraction” of light can be understood as any deviation of light rays from their geometrical propagation line (that is straight in a homogeneuos material) An example (shown in the picture):The edge of shadow is never perfectly sharp. Some light appears in the geometrical shadow, and there are dark and light fringers in the area of illumination.

  • Textbooks on radio antennas and propagation have changed little over the last 50 years. Invariably they base themselves on the famous electromagnetic equations described by James Clerk Max- well, a great nineteenth-century genius of theoretical physics (Torrance, 1982). Maxwell's equations brilliantly encompassed all the electromagnetic phenomena known by his time (except photo- electric long-wave cut-off, which remained ...

  • Chapter 1 is for readers who have less background in partial differential equations (PDEs). It contains materials which will be useful in understanding some of the jargon related to the rest of the chapters in this book. A discussion about the classification of the PDEs is presented. Here, we outline the major analytical methods. Later in the chapter, we introduce the most important numerical techniques, namely the finite difference method and finite element method. In the last section we briefly introduce the level set method.
