Mechanical Characterization of Materials and Wave Dispersion: Instrumentation and Experiment Interpretation

by Yvon Chevalier Jean Vinh Tuong

Over the last 50 years, the methods of investigating dynamic properties have resulted in significant advances. This book explores dynamic testing, the methods used, and the experiments performed, placing a particular emphasis on the context of bounded medium elastodynamics. Dynamic tests have proven to be as efficient as static tests and are often easier to use at lower frequency. The discussion is divided into four parts. Part A focuses on the complements of continuum mechanics. Part B concerns the various types of rod vibrations: extensional, bending, and torsional. Part C is devoted to mechanical and electronic instrumentation, and guidelines for which experimental set-up should be used are given. Part D concentrates on experiments and experimental interpretations of elastic or viscolelastic moduli. In addition, several chapters contain practical examples alongside theoretical discussion to facilitate the readers understanding. The results presented are the culmination of over 30 years of research by the authors and as such will be of great interest to anyone involved in this field.

Bipedal Robots: Modeling, Design and Walking Synthesis

by Christine Chevallereau Gabriel Abba Yannick Aoustin Guy Bessonnet

This book presents various techniques to carry out the gait modeling, the gait patterns synthesis, and the control of biped robots. Some general information on the human walking, a presentation of the current experimental biped robots, and the application of walking bipeds are given. The modeling is based on the decomposition on a walking step into different sub-phases depending on the way each foot stands into contact on the ground. The robot design is dealt with according to the mass repartition and the choice of the actuators. Different ways to generate walking patterns are considered, such as passive walking and gait synthesis performed using optimization technique. Control based on the robot modeling, neural network methods, or intuitive approaches are presented. The unilaterality of contact is dealt with using on-line adaptation of the desired motion.

Micropollutants in Large Lakes: From Potential Pollution Sources to Risk Assessments

by Nathalie Chevre

Scientists, regulators, and the general public are now more and more aware of the chemicals present in surface waters worldwide. Agrochemicals, such as herbicides or insecticides, pharmaceuticals and cosmetics can be detected at low to medium concentrations in seas, groundwaters and rivers. Among freshwaters, lakes are of particular concern. These large reservoirs are used as sources of food and drinking water, but also serve for recreational activities. This book aims in presenting insights into the physical, chemical, and ecological dynamics of large lakes that enable proposing recommendations for sustainable lake management regarding chemicals. Lake Geneva, Switzerland, is used as a case study, but the developed methodologies and tools can be useful for lake water quality management in general. A first chapter is dedicated to the chemicals entering the lake through agriculture. These are mainly pesticides. After a review of the different types of compounds, the authors present the main pathways these compounds follow to enter the lake. The case of glyphosate, an herbicide largely used worldwide, is presented. A second chapter illustrates the urban source of pollutants with the case of pharmaceuticals and biocides. Two models are presented that allow estimating the load and the dynamic of these chemicals that may exit from an urban catchment and therefore reach a lake. Special attention will be paid to the ‘end of pipe’ removal of these compounds at a WWTP. A third chapter is dedicated to the lake circulation. The aim of this chapter is to present an overall description of the lake’s hydrodynamics, which is driven by three factors: wind, temperature and Coriolis forces. To achieve this aim, a hydrodynamic model is presented that allows describing the behavior of the top layer of the lake based on the wind direction. The importance of stable hydrogen and oxygen isotopes for characterizing the sources of water and the mixing processes in the lake is also described. The next chapters are dedicated to a Bay, called the Vidy Bay, that receives the treated effluents of the largest wastewater treatment plant of the lake catchment. This latter represents therefore one of the major point sources of contaminants for lake Geneva. These two chapters will focus on the various processes that control the transfer of chemicals (associated to particles or in a dissolved state) discharged into the bay and transported to the lake’s main water body. Then, a next chapter focuses on one major issue of chemicals in aquatic systems like lakes, i.e. the risk of the mixture of chemicals. The evaluation of the risk of mixture is not trivial and the models that allow doing it are presented in a critical way. Their validity as predictive tools is illustrated with the example of herbicides mixture in Lake Geneva. A final chapter synthesizes the main findings and discusses some recommendations for the management of large lakes regarding micropollution.

by Daniel Chew Andrew L. Adams Jason Uher

Wireless Coexistence Explore a comprehensive review of the motivation for wireless coexistence and the standards and technology used to achieve it Wireless Coexistence: Standards, Challenges, and Intelligent Solutions delivers a thorough exploration of wireless ecosystems sharing the spectrum, including the multiple standards and key requirements driving the current state of wireless technology. The book surveys several standards, including IEEE 802.22, 802.15.2, and 802.19.1 and expands upon recent advances in machine learning and artificial intelligence to demonstrate how these technologies might be used to meet or exceed the challenges of wireless coexistence. The text discusses cognitive radio in the context of spectrum coexistence and provides a comparison and assessment of using artificial intelligence in place of, or in addition to, current techniques. It also considers applications to communication theory, learning algorithms for passive wireless coexistence strategies, spectrum situational awareness, and active wireless coexistence strategies. With the necessity of spectrum sharing and the scarcity of unused spectrum on the rise, the standardization of wireless coexistence becomes more important with each passing day. Readers will learn about the challenges posed by shrinking wireless real estate and from the inclusion of topics like: A thorough introduction to the concept of, and motivation for, wireless coexistence, including congestion and interference, policies, and regulations An exploration of different wireless coexistence standards, including the need for standardization and various protocols, including 802.22, 802.15.2, 802.19.1, P1900, and 3GPP Release 13/14 LAA A discussion of the applications of communication theory, including primary user strategies, primary multi-user protocols, and successive interference cancellation A treatment of concepts in learning algorithms Perfect for scientists, researchers, engineers, developers, educators, and administrators working in the area of wireless networks, Wireless Coexistence: Standards, Challenges, and Intelligent Solutions will also earn a place in the libraries of graduate students studying wireless networks and seeking a one-stop reference for subjects related to wireless coexistence standards.
