Freezing of Lakes and the Evolution of Their Ice Cover (Springer Praxis Books)

by Matti Leppäranta

This book updates the first edition for the status of knowledge in the physics of lake ice and the interactions between the ice cover and the liquid water underneath. Since the first edition was written in 2013, there has been a lot of progress in the field, in particular concerning environmental questions and the impact of climate change. Life conditions in ice-covered lakes and practical matters are now brought more into the picture so that the revision also properly serves as a handbook for applications. The author has worked widely with boreal lakes, polar lakes and Central Asian lakes that provides a wide geographical spectrum.Chapter 1 gives a brief overview and presents the research fields. The second chapter contains the classification of ice-covered lakes and observation techniques, especially remote sensing. In Chapter 3, the structure and properties of lake ice are presented including optics and geochemistry. Ice growth and melting are treated in Chapter 4, while the following chapter focuses on ice mechanics with applications to traffic on ice and ice loads. Chapter 6 goes into the exotic environment of pro-glacial lakes. Chapter 7 contains the stratification and circulation of the water body beneath lake ice, Chapter 8 presents the winter ecology of freezing lakes and discusses the lake ice interface toward the society, and Chapter 9 summarizes the climate change impact on lake ice seasons. The book ends into a brief closing chapter and list of references. Research problems for student learning are listed throughout the book. Annexes are included to provide numerical data of constants and standard formulae to help practical calculations and student tasks.Lake ice closely interacts with human living conditions, but people have learnt to live with that and to utilize the ice. In the present time this is true for on-ice traffic and recreation activities. Ice fishing has become a widely enjoyed hobby, and winter sports such as skiing, skating, and ice sailing are popular activities on frozen lakes. The lake ice response to eventual climate warming would appear as a shortening of the ice season due to the increasing air temperature and also as changing of the quality of the ice seasons via changes in ice thickness and structure. The book gives the whole story of lake ice into a single volume. The second, revised edition updates the content based on recent progress in winter limnology and ice physics research and applications. The author has contributed to lake ice research since the 1980s. In particular, his topics have been lake ice structure and thermodynamics, light transfer in ice and snow, ice mechanics in large lakes, and lake ice climatology. Mathematical modeling of ice growth, drift, and decay are covered in this research.

Frequency Domain Analysis and Design of Nonlinear Systems based on Volterra Series Expansion

by Xingjian Jing Ziqiang Lang

This book is a systematic summary of some new advances in the area of nonlinear analysis and design in the frequency domain, focusing on the application oriented theory and methods based on the GFRF concept, which is mainly done by the author in the past 8 years. The main results are formulated uniformly with a parametric characteristic approach, which provides a convenient and novel insight into nonlinear influence on system output response in terms of characteristic parameters and thus facilitate nonlinear analysis and design in the frequency domain. The book starts with a brief introduction to the background of nonlinear analysis in the frequency domain, followed by recursive algorithms for computation of GFRFs for different parametric models, and nonlinear output frequency properties. Thereafter the parametric characteristic analysis method is introduced, which leads to the new understanding and formulation of the GFRFs, and nonlinear characteristic output spectrum (nCOS) and the nCOS based analysis and design method. Based on the parametric characteristic approach, nonlinear influence in the frequency domain can be investigated with a novel insight, i. e. , alternating series, which is followed by some application results in vibration control. Magnitude bounds of frequency response functions of nonlinear systems can also be studied with a parametric characteristic approach, which result in novel parametric convergence criteria for any given parametric nonlinear model whose input-output relationship allows a convergent Volterra series expansion. This book targets those readers who are working in the areas related to nonlinear analysis and design, nonlinear signal processing, nonlinear system identification, nonlinear vibration control, and so on. It particularly serves as a good reference for those who are studying frequency domain methods for nonlinear systems.

Frequency Domain Nonlinear Vibration Features for Fault Diagnosis in Complex Structures

by Xingjian Jing Quankun Li

This book provides a comprehensive introduction to recent advances in frequency domain nonlinear vibration features utilized for fault diagnosis in complex structures in the field of mechanical, civil, aeronautical and aerospace engineering. It illustrates their basic principles, advantages, drawbacks and applications in detail through theoretical analysis and simulation/experimental study. This book focuses on frequency domain nonlinear vibration features and its main contents can be classified into two parts according to the introduced features. One is about features based on the SOOS (second-order output spectrum), and the other is about features based on the OS@DF (output spectrum at the double frequency or the second harmonic frequency). Complex structures in this book include satellites, aeroengines, bridges, pipelines, frames, etc., and corresponding multiple degree-of-freedom (MDOF) models include chain-type, beam-type, ring-like, grid-like, unit-like and rotating models. Detailed theoretical analysis and case demonstration help undergraduates, graduates and researchers have a systematical learning process and understand basic dynamic characteristics of complex structures more thoroughly. Then, some models, methods and results in this book can be a valid reference for the design, optimization and iteration of next-generation complex structures. On the other hand, this book provides a totally new inspiration for fault diagnosis methods combined with artificial intelligence and machine learning algorithms since frequency domain nonlinear vibration features introduced in this book are more sensitive and effective to faults.

Frequency Variations in Power Systems: Modeling, State Estimation, and Control (Wiley - IEEE)

by Federico Milano Alvaro Ortega Manjavacas

Frequency Variations in Power Systems: Modeling, State Estimation and Control presents the Frequency Divider Formula (FDF); a unique approach that defines, calculates and estimates the frequency in electrical energy systems. This authoritative book is written by two noted researchers on the topic. They define the meaning of frequency of an electrical quantity (such as voltage and current) in non-stationary conditions (for example the frequency is not equal to the nominal one) and pose the foundation of the frequency divider formula. The book describes the consequences of using a variable frequency in power system modelling and simulations, in state estimation and frequency control applications. In addition, the authors include a discussion on the applications of the frequency divider in systems where part of the generation is not based on synchronous machines, but rather on converter-interfaced energy resources, such as wind and solar power plants. This important book: Offers a review that clearly defines and shows how the Frequency Divider Formula can be applied Discusses the link between frequency and energy in power systems Presents a unified vision that accurately reveals the common thread that links modelling, control and estimation Includes information on the many implications that “local frequency variations” have on power system dynamics and control Contains several numerical examples Written for researchers, academic staff members, students, specialised consultants and professional software developers, Frequency Variations in Power Systems questions the conventional transient stability model of power system and proposes a new formulation.

Frequency-Domain Multiuser Detection for CDMA Systems (River Publishers Series In Communications Ser.)

by Rui Dinis Paulo Silva

Future broadband wireless communication systems are expected to be able to offer new and powerful services enabling fast transmission rates of several tens of Mbit/s. This is an ambitious challenge especially for mobile communication systems since these systems should be able to cope with severely time dispersive channels, associated to the signal multipath propagation. Moreover, these systems should have high spectral and power efficiencies, as well as high capacity and flexibility. Spread spectrum techniques, particularly coded division multiple access (CDMA) techniques allow high capacity and flexibility, continuous transmission requiring low-peak power requirements for the amplifiers, as well as some robustness against fading and time-dispersion effects associated with the multipath propagation. When employed in prefix assisted (PA) block transmission schemes combined with frequency-domain receiver implementations they become especially interesting for broadband wireless systems. In Frequency-Domain Multiuser Detection for CDMA Systems the use of PA block transmission is considered in the context of both DS (Direct Sequence) and MC (Multicarrier) CDMA schemes. The main goal is the study of frequency-domain multiuser detection techniques with iterative signal detection/decoding techniques, also in combination with estimation and cancelation of nonlinear distortion effects. The receiver structures are suitable to scenarios with high interference levels and strongly time-dispersive channels.

Fresh: A Perishable History

by Susanne Freidberg

That rosy tomato perched on your plate in December is at the end of a great journey—not just over land and sea, but across a vast and varied cultural history. This is the territory charted in Fresh. Opening the door of an ordinary refrigerator, it tells the curious story of the quality stored inside: freshness. We want fresh foods to keep us healthy, and to connect us to nature and community. We also want them convenient, pretty, and cheap. Fresh traces our paradoxical hunger to its roots in the rise of mass consumption, when freshness seemed both proof of and an antidote to progress. Susanne Freidberg begins with refrigeration, a trend as controversial at the turn of the twentieth century as genetically modified crops are today. Consumers blamed cold storage for high prices and rotten eggs but, ultimately, aggressive marketing, advances in technology, and new ideas about health and hygiene overcame this distrust. Freidberg then takes six common foods from the refrigerator to discover what each has to say about our notions of freshness. Fruit, for instance, shows why beauty trumped taste at a surprisingly early date. In the case of fish, we see how the value of a living, quivering catch has ironically hastened the death of species. And of all supermarket staples, why has milk remained the most stubbornly local? Local livelihoods; global trade; the politics of taste, community, and environmental change: all enter into this lively, surprising, yet sobering tale about the nature and cost of our hunger for freshness.

by Jay Huner

Freshwater Crayfish Aquaculture in North America, Europe, and Australia is the first text to summarize the methods of culture for the eight most important crayfish species in the world. Methods developed to culture crayfishes around the world differ significantly, and this book enables readers to develop workable strategies for cultivating different crayfish species in specific environments. Huner and associate authors cover the following topics in detail: methods of crayfish culture crayfish diseases crayfish processing economics of crayfish cultureEach of the the three major crayfish industries are well-represented in this new book and special attention is given to the specific needs and accomplishments of each area, which is beneficial to producers in other countries. For example, while hatching technology has been important in Australia and Europe, it hasn?t yet been applied to any degree in North America. At the same time, North America has developed a major crayfish processing industry. Disease problems have resulted in more emphasis on that subject in Europe and yet it is vital to all involved in crayfish aquaculture. Businessmen, farmers, scientists, laymen, or students need to be exposed to the methods and problems associated with crayfish production in different parts of the world if they are to be successful in any crayfish project, whether it be research- or profit-oriented. Freshwater Crayfish Aquaculture in North America, Europe, and Australia is intended to provide all readers with one source of information on the subject of freshwater crayfish aquaculture.Professional staff, advanced students, and extension personnel will find the entire text beneficial.

Here, separate male and female keys to the calanoid copepods are provided for both the genera and species levels.

Freshwater Ecosystems: Revitalizing Educational Programs in Limnology

by Committee on Inland Aquatic Ecosystems

To fulfill its commitment to clean water, the United States depends on limnology, a multidisciplinary science that seeks to understand the behavior of freshwater bodies by integrating aspects of all basic sciences--from chemistry and fluid mechanics to botany, ichthyology, and microbiology. Now, prominent limnologists are concerned about this important field, citing the lack of adequate educational programs and other issues. Freshwater Ecosystems responds with recommendations for strengthening the field and ensuring the readiness of the next generation of practitioners. Highlighted with case studies, this book explores limnology's place in the university structure and the need for curriculum reform, with concrete suggestions for curricula and field research at the undergraduate, graduate, and postdoctoral levels. The volume examines the wide-ranging career opportunities for limnologists and recommends strategies for integrating limnology more fully into water resource decision management. Freshwater Ecosystems tells the story of limnology and its most prominent practitioners and examines the current strengths and weaknesses of the field. The committee discusses how limnology can contribute to appropriate policies for industrial waste, wetlands destruction, the release of greenhouse gases, extensive damming of rivers, the zebra mussel and other "invasions" of species-- the broad spectrum of problems that threaten the nation's freshwater supply. Freshwater Ecosystems provides the foundation for improving a field whose importance will continue to increase as human populations grow and place even greater demands on freshwater resources. This volume will be of value to administrators of university and government science programs, faculty and students in aquatic science, aquatic resource managers, and clean-water advocates--and it is readily accessible to the concerned individual.
