Download or read book An Introduction to Tree Ring Dating written by Marvin A. Stokes and published by University of Arizona Press. This book was released on 2022-05-03 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tree-ring dating, or dendrochronology, is the study of the chronological sequence of annual growth rings in trees. This book--a seminal study in its field--provides a simple yet eloquent introduction to the discipline, explaining what a dendrochronologist does both in the field and in the laboratory. Authors Stokes and Smiley first explain the basic principles of tree-ring dating, then describe details of the process, step by step, from the time a sample is collected until it is incorporated into a master chronology. The book focuses on coniferous evergreens of the Southwest, particularly piñons, because they have wide geographic distribution, constitute a large population, and show excellent growth response to certain controlling factors. The book is specifically concerned with the task of establishing a calendar date for a wood or charcoal specimen. This concise but thorough explication of an important discipline will make dendrochonology more meaningful to students and professionals in archaeology, forestry, hydrology, and global change.
Download or read book Tree Thinking An Introduction to Phylogenetic Biology written by David A. Baum and published by Roberts. This book was released on 2012-08-10 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Baum and Smith, both professors evolutionary biology and researchers in the field of systematics, present this highly accessible introduction to phylogenetics and its importance in modern biology. Ever since Darwin, the evolutionary histories of organisms have been portrayed in the form of branching trees or “phylogenies.” However, the broad significance of the phylogenetic trees has come to be appreciated only quite recently. Phylogenetics has myriad applications in biology, from discovering the features present in ancestral organisms, to finding the sources of invasive species and infectious diseases, to identifying our closest living (and extinct) hominid relatives. Taking a conceptual approach, Tree Thinking introduces readers to the interpretation of phylogenetic trees, how these trees can be reconstructed, and how they can be used to answer biological questions. Examples and vivid metaphors are incorporated throughout, and each chapter concludes with a set of problems, valuable for both students and teachers. Tree Thinking is must-have textbook for any student seeking a solid foundation in this fundamental area of evolutionary biology.
Download or read book Introduction to Forest and Shade Tree Insects written by Bozzano G Luisa and published by Elsevier. This book was released on 2012-12-02 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehenisive text approaches the subject from an ecological/evolutionary biological perspective. The assumption is that one cannot study forest insects without understanding the dynamics of the relationship between an insect and its host plant. This relationship includes knowing what factors control forest insect populations such as food, food quality, tree vigor, host selection, and symbiotic relationships. The authors also discuss tree-injuring insects from the perspective of their influence on tree physiology and growth as well as economic and commercial effects. The book represents a "modern" approach to the topic of forest and shade tree insects; is well-illustrated; and includes a comprehensive primary reference list.
Download or read book Behavior Trees in Robotics and AI written by Michele Colledanchise and published by CRC Press. This book was released on 2018-07-20 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Behavior Trees (BTs) provide a way to structure the behavior of an artificial agent such as a robot or a non-player character in a computer game. Traditional design methods, such as finite state machines, are known to produce brittle behaviors when complexity increases, making it very hard to add features without breaking existing functionality. BTs were created to address this very problem, and enables the creation of systems that are both modular and reactive. Behavior Trees in Robotics and AI: An Introduction provides a broad introduction as well as an in-depth exploration of the topic, and is the first comprehensive book on the use of BTs. This book introduces the subject of BTs from simple topics, such as semantics and design principles, to complex topics, such as learning and task planning. For each topic, the authors provide a set of examples, ranging from simple illustrations to realistic complex behaviors, to enable the reader to successfully combine theory with practice. Starting with an introduction to BTs, the book then describes how BTs relate to, and in many cases, generalize earlier switching structures, or control architectures. These ideas are then used as a foundation for a set of efficient and easy to use design principles. The book then presents a set of important extensions and provides a set of tools for formally analyzing these extensions using a state space formulation of BTs. With the new analysis tools, the book then formalizes the descriptions of how BTs generalize earlier approaches and shows how BTs can be automatically generated using planning and learning. The final part of the book provides an extended set of tools to capture the behavior of Stochastic BTs, where the outcomes of actions are described by probabilities. These tools enable the computation of both success probabilities and time to completion. This book targets a broad audience, including both students and professionals interested in modeling complex behaviors for robots, game characters, or other AI agents. Readers can choose at which depth and pace they want to learn the subject, depending on their needs and background.

Available in PDF, EPUB and Kindle. Book excerpt: An Introduction to Statistical Learning provides an accessible overview of the field of statistical learning, an essential toolset for making sense of the vast and complex data sets that have emerged in fields ranging from biology to finance, marketing, and astrophysics in the past twenty years. This book presents some of the most important modeling and prediction techniques, along with relevant applications. Topics include linear regression, classification, resampling methods, shrinkage approaches, tree-based methods, support vector machines, clustering, deep learning, survival analysis, multiple testing, and more. Color graphics and real-world examples are used to illustrate the methods presented. This book is targeted at statisticians and non-statisticians alike, who wish to use cutting-edge statistical learning techniques to analyze their data. Four of the authors co-wrote An Introduction to Statistical Learning, With Applications in R (ISLR), which has become a mainstay of undergraduate and graduate classrooms worldwide, as well as an important reference book for data scientists. One of the keys to its success was that each chapter contains a tutorial on implementing the analyses and methods presented in the R scientific computing environment. However, in recent years Python has become a popular language for data science, and there has been increasing demand for a Python-based alternative to ISLR. Hence, this book (ISLP) covers the same materials as ISLR but with labs implemented in Python. These labs will be useful both for Python novices, as well as experienced users.

Download or read book Introduction to lambda trees written by Ian Chiswell and published by World Scientific. This book was released on 2001 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theory of ?-trees has its origin in the work of Lyndon on length functions in groups. The first definition of an R-tree was given by Tits in 1977. The importance of ?-trees was established by Morgan and Shalen, who showed how to compactify a generalisation of Teichmller space for a finitely generated group using R-trees. In that work they were led to define the idea of a ?-tree, where ? is an arbitrary ordered abelian group. Since then there has been much progress in understanding the structure of groups acting on R-trees, notably Rips' theorem on free actions. There has also been some progress for certain other ordered abelian groups ?, including some interesting connections with model theory.Introduction to ?-Trees will prove to be useful for mathematicians and research students in algebra and topology.
