Tracer Technology
by Octave LevenspielThe tracer method was first introduced to measure the actual flow of fluid in a vessel, and then to develop a suitable model to represent this flow. Such models are used to follow the flow of fluid in chemical reactors and other process units, in rivers and streams, and through soils and porous structures. Also, in medicine they are used to study the flow of chemicals, harmful or not, in the blood streams of animals and man. Tracer Technology, written by Octave Levenspiel, shows how we use tracers to follow the flow of fluids and then we develop a variety of models to represent these flows. This activity is called tracer technology.
Traces of Common Xylophagous Insects in Wood: Atlas of Identification - Western Europe
by Magali Toriti Aline Durand Fabien FohrerThis atlas presents a concrete tool to identify xylophagous activity by the remains they left in wooded areas in Western Europe. Xylophagous insects are among the largest predators of woody tissues. They leave discriminating traces, different for each species according to their bioecology, and so it is necessary to know how to recognize and characterize them. The book is a practical tool to help identify and interpret them through a standardized presentation of the most ubiquitous families and a key to their determination. It presents descriptions of the galleries and of morphometry of the faecal pellets based on macroscopic features for xylophagous identification, and includes information about the origin and distribution of the xylophagous biological cycles, bioclimatic conditions and bioecology, and the type of woods that are attacked. The book will be a useful guide for forest managers, heritage conservationists, environmental engineers, bioarchaeologists, entomologists, loggers, and wood anatomists.

Tracing the Sources and Fate of Contaminants in Agroecosystems: Applications of Multi-stable Isotopes
by Lee Heng Joseph Adu-Gyamfi Grzegorz Skrzypek Gwenaël ImfeldThe objective of this open access book is to present protocols, methodologies, and standard operating procedures (SOPs) used for the identification of sources, transport, and fate of agro-contaminants and illustrate them with several case studies of successful applications. The Soil and Water Management & Crop Nutrition (SWMCN) Subprogramme of the Joint Food and Agriculture Organization (FAO)/International Atomic Energy Agency (IAEA) Centre of Nuclear Techniques in Food and Agriculture, through a Coordinated Research Project (CRP) in partnership with national and international research institutes, developed and evaluated a set of analytical techniques (the toolbox). The toolbox integrates multiple isotope tracers that provide information on the origins and pathways of multiple pollutants through agro-ecosystems, thereby providing more accurate guidance on mitigations. However, land management strategies to address and control the transport of pollutants from soil to water bodies remain the shared responsibility of farm and aquaculture operators, agro-chemical manufacturers, and policymakers in food and agriculture as well as the mining sectors. This book is structured into eight chapters covering (i) an overview of the book’s content, (ii) guidelines for designing water sampling programmes, (iii) the use of mixing models applicable to tracers for water pollution studies, (iv) compound-specific isotope analyses to investigate pesticide degradation in agricultural catchments, (v) the use of stable oxygen isotope composition of phosphate to investigate phosphorous in soil-plant continuum, (vi) the use of stable sulphur isotopes to disentangle agro-pollutants from other contaminants, (vii) nuclear tools used in sediment source apportionment, and (viii) the conclusions and perspectives forward. The book offers up-to-date information, and we hope it is a great source of information for students, researchers, and policymakers. The SWMCN subprogramme thanks all the contributors involved in the preparation of this publication.

Tracking and Sensor Data Fusion
by Wolfgang KochSensor Data Fusion is the process of combining incomplete and imperfect pieces of mutually complementary sensor information in such a way that a better understanding of an underlying real-world phenomenon is achieved. Typically, this insight is either unobtainable otherwise or a fusion result exceeds what can be produced from a single sensor output in accuracy, reliability, or cost. This book provides an introduction Sensor Data Fusion, as an information technology as well as a branch of engineering science and informatics. Part I presents a coherent methodological framework, thus providing the prerequisites for discussing selected applications in Part II of the book. The presentation mirrors the author's views on the subject and emphasizes his own contributions to the development of particular aspects. With some delay, Sensor Data Fusion is likely to develop along lines similar to the evolution of another modern key technology whose origin is in the military domain, the Internet. It is the author's firm conviction that until now, scientists and engineers have only scratched the surface of the vast range of opportunities for research, engineering, and product development that still waits to be explored: the Internet of the Sensors.
Tracking Control of Linear Systems
by Lyubomir T. GruyitchThe primary purpose of control is to force desired behavior in an unpredictable environment, under the actions of unknown, possibly unmeasurable disturbances and unpredictable, and therefore probably nonzero, initial conditions. This means that tracking and tracking control synthesis are fundamental control issues. Surprisingly, however, tracking theory has not been well developed, and stability theory has dominated. Tracking Control of Linear Systems presents the fundamentals of tracking theory for control systems. The book introduces the full transfer function matrix F(s), which substantially changes the theory of linear dynamical and control systems and enables a novel synthesis of tracking control that works more effectively in real environments.An Introduction to the New Fundamentals of the Theory of Linear Control SystemsThe book begins by re-examining classic linear control systems theory. It then defines and determines the system full (complete) transfer function matrix F(s) for two classes of systems: input-output (IO) control systems and input-state-output (ISO) control systems. The book also discusses the fundamentals of tracking and trackability. It presents new Lyapunov tracking control algorithms and natural tracking control (NTC) algorithms, which ensure the quality of the tracking under arbitrary disturbances and initial conditions. This natural tracking control is robust, adaptable, and simple to implement.Advances in Linear Control Systems Theory: Tracking and TrackabilityThis book familiarizes readers with novel, sophisticated approaches and methods for tracking control design in real conditions. Contributing to the advancement of linear control systems theory, this work opens new directions for research in time-invariant continuous-time linear control systems. It builds on previous works in the field, extending treatment o

Tracking People: Wearable Technologies in Social and Public Policy
by Raymond HoltTracking technologies are now ubiquitous and are part of many people’s everyday lives. Large sections of the population voluntarily use devices and apps to track fitness, medical conditions, sleep, vital signs or their own or others’ whereabouts. Governments, health services, immigration and criminal justice agencies increasingly rely upon tracking technologies to monitor individuals’ whereabouts, behaviour, medical conditions and interventions. Despite the human rights concerns of some organisations and individuals, most wearers and their significant others tend to welcome the technologies. This paradox is only one of the many fascinating challenges raised by the widespread use of tracking technologies which are explored in this book. This book critically explores the ethical, legal, social, and technical issues arising from the current and future use of tracking technologies. It provides a unique and wide-ranging discussion, via a cross-disciplinary collection of essays, on issues relating to technological devices and apps whose use is imposed upon wearers or suggested by others, whether agencies or individuals, including in the domains of criminal justice, terrorism, and health and social care. Contributions from leading academics from across social sciences, engineering, computer and data science, philosophy, and health and social care address the diverse uses of tracking technologies including with individuals with dementia, defendants and offenders, individuals with mental health conditions and drug users alongside legal, ethical and normative questions about the appropriate use of these technologies. Cross-disciplinary themes emerge focusing on both the benefits of the technologies – freedom, improved safety, security, well-being and autonomy, and increased capacity of and efficiencies for public services – and the challenges – implementation and operational costs, mission creep, privacy concerns, stigmatisation, whether the technologies work as expected, and useability and wearability for all wearers. This book is essential reading for academics and students engaged in criminology, criminal justice, socio-legal studies, science and technology studies, medicine, health and social care, psychology, engineering, computer and data science, philosophy, social policy and social work and security studies. It will also be of great interest to policy-makers, regulators, practitioners already deploying or considering using tracking technologies, and to current and potential wearers.
Tracking with Particle Filter for High-dimensional Observation and State Spaces
by Séverine DubuissonThis title concerns the use of a particle filter framework to track objects defined in high-dimensional state-spaces using high-dimensional observation spaces. Current tracking applications require us to consider complex models for objects (articulated objects, multiple objects, multiple fragments, etc.) as well as multiple kinds of information (multiple cameras, multiple modalities, etc.). This book presents some recent research that considers the main bottleneck of particle filtering frameworks (high dimensional state spaces) for tracking in such difficult conditions.
