Farbenphysik für industrielle Anwendungen by Georg A. Klein

By Georg A. Klein

Die vielf?ltigen klassischen und neuen industriellen Farbmittel sind ohne fundierte farbenphysikalische Kenntnisse nicht gezielt anwendbar.

Abgesehen von der Einleitung beginnt jedes Kapitel des Buches mit einem Vorspann, der dem Leser einen ?berblick ?ber die behandelte Thematik und deren Bedeutung bietet. Die Ausf?hrungen untergliedern sich in drei Teile. Der erste Teil umfasst die Kapitel mit den Grundlagen zur Farbenphysik, zur Farbmetrik, deren wichtigste industrielle Anwendungen und zur Farbmessung. Die n?chsten Kapitel bilden den zweiten teil, der den optischen Strahlungstransport nach der Zwei-, Drei- und Multikanal-N?herung jeweils einschlie?lich der Grenzfl?chen-Korrekturen beschreibt. Mit diesen N?herungen liegen wesentliche Voraussetzungen vor zur Farbrezept-Vorausberechnung mit mehreren Strategien; diese ist ausf?hrlich im letzten teil dargestellt.

Die Ausf?hrungen werden erg?nzt durch 20 Tabellen, mehr als a hundred z.T. mehrfarbige Abbildungen, einen Anhang und ein umfangreiches, alphabetisch geordnetes Literturverzeichnis. Das Buch ist als unverzeichtbare Informationsquelle gedacht f?r alle mit Farbmitteln T?tigen in Lehre, Forschung, Entwicklung, Produktion, Applikation oder Verarbeitung.      

Professor Klein promovierte an der Johannes Gutenberg-Universtit?t Mainz ?ber ein Thema der Polymerphysik. Forschungs- und Entwicklungst?tigkeiten in der chemischen Gro?industrie, 1978 Professur f?r Physik, Farbenphysik und Kunststoff-Technik im Fachbereich Farbe-Lack-Kunststoff an der Hochschule der Medien, Stuttgart, Forschungsgebiete: Farbenphysik und Physik der Hochpolymeren.

Tools of Radio Astronomy by Thomas L. Wilson, Kristen Rohlfs, Susanne Hüttemeister

By Thomas L. Wilson, Kristen Rohlfs, Susanne Hüttemeister

This sixth variation of “Tools of Radio Astronomy”, the main used introductory textual content in radio astronomy, has been revised to mirror the present kingdom of this significant department of astronomy. This comprises using satellites, low radio frequencies, the millimeter/sub-mm universe, the Cosmic Microwave historical past and the elevated value of mm/sub-mm dirt emission.

Several derivations and displays of technical elements of radio astronomy and receivers, comparable to receiver noise, the Hertz dipole and beam forming were up to date, multiplied, re-worked or complemented by way of replacement derivations. those mirror advances in know-how.

The wider bandwidths of the Jansky-VLA and lengthy wave arrays comparable to LOFAR and mm/sub-mm arrays resembling ALMA required a spread of the dialogue of interferometers and aperture synthesis. advancements in information aid algorithms were integrated.

As end result of the the big volume of knowledge accumulated some time past two decades, the dialogue of sun process radio astronomy, airborne dirt and dust emission, and radio supernovae has been revisited.

The chapters on spectral line emission were up to date to hide measurements of the impartial hydrogen radiation from the early universe in addition to measurements with new amenities. equally the dialogue of molecules in interstellar house has been increased to incorporate the molecular and mud emission from protostars and intensely chilly areas.

Several labored examples were extra within the components of primary physics, equivalent to pulsars.

Both scholars and practising astronomers will enjoy this new up to date variation of instruments of Radio Astronomy.

Low-Power Wireless Infrared Communications by Rob Otte

By Rob Otte

Today, instant infrared transmission has entered our houses, workplaces, and healthiness care, with functions within the box of handheld remote control, telemetry, and native communique. This publication is set the underlying expertise. because it is an outgrowth of my Ph.D. thesis, the emphasis is on basic facets instead of business features, just like the standardization attempt via the IrDA [7]. i suppose that this isn't an obstacle, as, ultimately, the legislation of physics practice to we all! because the utilized radiation isn't really inevitably within the infrared, in the course of the ebook we often favor the time period optical transmission. As such a lot apparatus is battery-powered, the emphasis is on strength optimiza­ tion of the optical transmission process. process parameters in addition to environ­ psychological parameters that ensure the eventual transmission caliber are iden­ tified, to facilitate well-reasoned method layout. Many layout principles, in response to calculations, measurements and simulations are awarded to assist the clothier push the functionality with reference to the bounds set by way of nature and the to be had tech­ nology. the 1st chapters introduce the topic and the current the scope of the ebook. Then, the elemental transmission hyperlink is brought in bankruptcy three, and strate­ gies to optimize its signal-to-noise ratio are mentioned. lighting fixtures flicker is identi­ fied as a potential resource of interference. Then, receiver noise and bandwidth are mentioned in bankruptcy four, typically in accordance with the cloth offered in [66], [67], [69].
