Fluidization: International Fluidization Conference
by John M. Matsen John R. GraceFluidized beds have gained prominence in many process in dustries (including chemicals, petroleum, metallurgy, food and pharmaceuticals) as a means of bringing particulate solids into contact with gases and/or liquids. Many fluidized bed operations are physical in nature (e.g. drying, coating, classification, granulation, and rapid heat transfer as in quenching or annealing). Other operations involve chemical reactions including the cata lytic cracking of hydrocarbons, the manufacture of acry10nitrite and phthalic anhydride, the roasting of metallurgical ores, and the regeneration of spent catalysts. In recent years fluidized beds have been of special interest because of their potential as the central component in new processes for utilizing coal as a source of energy, notably in coal combustion and gasification processes. The fluidized bed offers a number of advantages over most other methods of contacting, in particular high rates of heat transfer, temperature uniformity and solids mobility. Among the disadvantages are particle losses by entrainment, attrition of solids, limited reactor efficiency due to gas bypassing and gas and solids backmixing, and difficulties in design and scale-up due to the complexity of fluidized beds. The International Fluidization Conference held in Henniker, New Hampshire, U.S.A. from 3-8 August 1980 was the fifth inter national congress devoted to the entire field of fluidization.
Fluidization of Fine Powders: Cohesive versus Dynamical Aggregation (Particle Technology Series #18)
by José Manuel Valverde MillánThis book covers the rich phenomenology exhibited by fine powders when they are fluidized by a gas flow. Fine powder cohesiveness leads to poor flowability, clumping, difficulty in fluidizing, irregular avalanching behavior, etc. Despite all the inconveniences, fine powder processes pervade the chemical, pharmaceutical, agricultural and mining industries among others. The author in this book analyzes the mechanism by which interparticle adhesive forces are reduced by means of surface additives. Different techniques have been developed in the last years to assist fluidization by helping the gas flow to mobilize and break cohesive aggregates, which help to homogenize fluidization. As reviewed in this book, the use of these techniques may have a relevant impact on novel processes based on fluidized beds of fine powder and with relevant applications on leading edge technologies such as Atomic Layer Deposition on nanoparticles and CO2 capture by gas-fluidized beds of adsorbent powders. The study of fluidized beds has a marked interdisciplinary character. This book is thus intended for academic and industrial researchers in applied physics, mechanical, chemical, and environmental engineering, who are interested in the special characteristics of fine powders.
Fluidized-Bed Reactors: Processes and Operating Conditions (Particle Technology Series #26)
by John G. Yates Paola LettieriThe fluidized-bed reactor is the centerpiece of industrial fluidization processes. This book focuses on the design and operation of fluidized beds in many different industrial processes, emphasizing the rationale for choosing fluidized beds for each particular process. The book starts with a brief history of fluidization from its inception in the 1940’s. The authors present both the fluid dynamics of gas-solid fluidized beds and the extensive experimental studies of operating systems and they set them in the context of operating processes that use fluid-bed reactors. Chemical engineering students and postdocs as well as practicing engineers will find great interest in this book.

Fluidware: Novel Approaches for Large-Scale IoT Systems (Internet of Things)
by Giancarlo Fortino Franco Zambonelli Mirko Viroli Barbara ReThis book provides an overview of the many approaches that can adopted for programming and deploying highly-adaptive and large-scale IoT systems, with a specific focus on the key results achieved within the Fluidware research project. The authors start by presenting Fluidware, which develops a novel programming model for IoT services and applications, along with the associated and robust large-scale IoT services and applications. Starting from previous findings in the areas of field-based coordination, collective adaptive systems, stream computing and aggregate computing, the authors address the complexity of building modern, large-scale IoT systems, by a full-fledged engineering approach revolving around a new notion of distributed programming. The authors show how the key innovative idea of Fluidware is to abstract collectives of devices of the IoT fabric as sources, digesters, and targets of distributed "flows" of contextualized events, carrying information about data produced and actuating commands. The book is divided into three parts: (i) the first part is a general introduction to the Fluidware ideas and to the key problems associated with programming IoT systems, (ii) the second part presents the key results achieved within the Fluidware project; (iii) the third part identified open challenges and research directions.
Fluktuationen und Dynamik aktiver Halbleiter-Bauelemente
by Wolfgang HarthAktive Halbleiter-Bauelemente können zur Umsetzung von Gleichleistung in Wechselleistung herangezogen werden. Bei den hier beispielhaft behandelten aktiven Zweipolen kann durch interne Rückkopplung ein negativer Widerstand auftreten, mit dem ein Resonator entdämpft wird und somit ein Oszillator entsteht. Dieser Oszillator wird charakterisiert durch seine Amplitude und Frequenz sowie deren Fluktuationen, nämlich Amplituden- und Frequenzrauschen. Damit ein Oszillator überhaupt einen stabilen Arbeitspunkt erreicht, muß das zugehörige aktive Bauelement eine nichtlineare Aussteuer-Charakteristik aufweisen. Bei der Beschreibung der Fluktuationen solcher Bauelemente muß daher die Kenntnis ihrer Dynamik vorausgehen. Dieses Buch behandelt Fluktuationsphänomene und deren Einfluß auf die Dynamik von aktiven Halbleiter-Bauelementen und stellt die vier wichtigsten Rauscheinströmungen ausfürhlich dar: äquivalentes thermisches Rauschen eines negativen Widerstandes, spontane Emission, Schrotrauschen und Rauschen heißer Elektronen. Diese Fluktuationen beeinflussen dabei wesentlich die Funktionseigenschaften des Van der Pol-Oszillators mit negativem, nichtlinearem Widerstand, des Injektionslasers sowie der Lawinenlaufzeit-Diode und des Gunn-Elements. Mit Hilfe der Langevin-Gleichungen, der Fokker-Planck- und Master-Gleichung werden zusammen mit den entsprechenden Autokorrelationsfunktionen jeweils die spektralen Dichten für Amplitude, Phase und Ausgangsleistung sowie Linienbreite und Rauschmaß bestimmt. Dieses Buch vermittelt Studierenden der Elektrotechnik und der Physik ein vertieftes Verständnis aktiver Halbleiter-Bauelemente aus den Bereichen Hochfrequenz-Elektronik und Opto-Elektronik. Dem Ingenieur in der Praxis kann diese Monographie eine nützliche Einführung in stochastische Phänomene auf diesem Gebiet sein. Vorausgesetzt werden Grundkenntnisse über Differentialgleichungen und Funktionentheorie.

Fluorescence in Bio-inspired Nanotechnology: First as Probe, Then as Function (Springer Theses)
by Jonas HannestadIn his thesis Fluorescence in Bio-inspired Nanotechnology, Jonas Hannestad describes the evolving field of DNA nanotechnology in a lucid and easily accessible way. A central theme in the thesis is how biological structures and mechanisms constitute a basis for the design of novel technologies. Hannestad discusses how self-assembled, nanometer-scale DNA constructs can be functionalized using fluorescent labeling. In particular, he highlights how applications are based on fluorescence resonance energy transfer (FRET). Another important contribution is the development of a lipid monolayer platform for the step-by-step assembly of DNA nanoconstructs. The work in the thesis is based on five peer-reviewed papers published in high-profile journals, all of which involve major contributions from the author.
Fluorescence Lifetime Imaging Ophthalmoscopy
by Martin Zinkernagel Chantal DysliThis book focuses on the emerging non-invasive imaging technique of Fluorescence Lifetime Imaging Ophthalmoscopy (FLIO). FLIO reveals unique information on retinal diseases, ranging from age-related macular degeneration and vascular diseases to hereditary retinal dystrophies.

The image acquisition is suitable for diagnostic purposes and follow-up examinations to investigate the natural course of disease, and to monitor the effects of possible therapies. This book fills the gap between available literature and gives state-of-the-art guidance on the principles of the FLIO technique, image acquisition, and data analysis. Written by a team of expert leaders within this field, this book will be relevant for scientists and clinicians with an interest in ophthalmoscopy.
