Available in PDF, EPUB and Kindle. Book excerpt: Photon correlation is a kind of spectroscopy designed to identify optical frequency shifts and line-broadening effects in the range of many MHz down to a few Hz. The optical intensity is measured in terms of single photon detection events which result in current pulses at the output of photomulti plier tubes. This signal is processed in real time in a special-purpose paral lel processor known as a correlator. The resulting photon correlation func tion, a function in the time domain, contains the desired spectral informa tion, which may be extracted by a suitable algorithm. Due to the non-intrusive nature and the sound theoretical basis of photon correlation, the phenomena under study are not disturbed, and the parameters in question can be precisely evaluated. For these reasons photon correlation has become a valuable and in many instances indispensable technique in two distinct fields. One of these is velocimetry in fluid flow. This includes hydro- and aerodynamic processes in liquids, gases, or flames where the velo city field may be stationary, time periodic, or turbulent, and may range from micrometers per second for motion inside biological cells to one kilometer per second for supersonic flow. The other major field is stochastic particle propagation due to Brownian motion.

This book was released on 1977 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this work was to provide the theory and a system design for a new type of photon-counting processor for low-level Dual Scatter laser velocimeter (LV) signals which would be capable of both the first-order measurements of mean-flow and turbulence-intensity and also the second order time statistics: cross-correlation, auto-correlation, and related spectra. A general Poisson process model for low-level LV signals and noise which is valid from the photon- resolved regime all the way to the limiting case of non- stationary Gaussian noise was used. Computer simulation algorithms and higher order statistical moment analysis of Poisson processes have been derived and applied to the analysis of photon correlation techniques. A system design using a unique Dual Correlate and Subtract frequency discriminator technique is postulated and analyzed. Expectation analysis indicates that the objective measurements are feasible. Error analysis for the mean-flow case indicates that practical transonic wind tunnel measurements are possible with 100-1000 times less light than is required for burst-counter processors. A system design for a new high-speed photon processor for LV signals is provided.

Available in PDF, EPUB and Kindle. Book excerpt: The study of estuaries and coasts has seen enormous growth in recent years, since changes in these areas have a large effect on the food chain, as well as on the physics and chemistry of the ocean. As the coasts and river banks around the world become more densely populated, the pressure on these ecosystems intensifies, putting a new focus on environmental, socio-economic and policy issues. Written by a team of international expert scientists, under the guidance of Chief Editors Eric Wolanski and Donald McClusky, the Treatise on Estuarine and Coastal Science, Ten Volume Set examines topics in depth, and aims to provide a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Most up-to-date reference for system-based coastal and estuarine science and management, from the inland watershed to the ocean shelf Chief editors have assembled a world-class team of volume editors and contributing authors Approach focuses on the physical, biological, chemistry, ecosystem, human, ecological and economics processes, to show how to best use multidisciplinary science to ensure earth's sustainability Provides a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Features up-to-date chapters covering a full range of topics
