With nearly twenty men engaged, Willoughbys kitchen garden was appreciably expanding. The survivors from twelve hours ago worked willingly, but of a pair engaged in breaking ground, one seemed less than used to it.

Willows by the water glittered, rustling in the blowing breeze. Mirrored in the limpid distance, silver gilt between the trees, bands of amber streaked the surface, gently rent the shroud of night, freed the sovereignty of darkness, put the dying clouds to flight. For Willoughby, it was the silent time. Profiled at the misty margin, contemplating whence she came, bent a water nymph in study, rapt and tranquil, lovely, lonely; a film veiled her slender limbs, limned softly by the suns first flame. Head lifted, she began to straighten, circling arms began to rise, fingers languidly caressed the tresses. Washed with light, she closed her eyes. A vision only, but not wholly, she is very like anothers form: gorgeous daughter of the morning, born into the warmth of dawn. It always seemed she might be waiting, though never as she seemed so now . . . Fastening her glowing hair, she drifted to the liquid lip. There, letting fall the gossamer, she slipped to mingle with the ripples. Grey eyes turned to smile a greeting, and white hand lingered in a parting wave . . . And she was gone. In the rushes at the lakeside, the dreamer, dreaming, gave a sigh. Could he make the scene substantial? Should hedare heeven try?

Introductory, theory-practice balanced text teaching the fundamentals of databases to advanced undergraduates or graduate students in information systems or computer science.

This is an excellent, up-to-date and easy-to-use text on data structures and algorithms that is intended for undergraduates in computer science and information science. The thirteen chapters, written by an international group of experienced teachers, cover the fundamental concepts of algorithms and most of the important data structures as well as the concept of interface design. The book contains many examples and diagrams. Whenever appropriate, program codes are included to facilitate learning.This book is supported by an international group of authors who are experts on data structures and algorithms, through its website at www.cs.pitt.edu/~jung/GrowingBook/, so that both teachers and students can benefit from their expertise.

An introduction to applying predicate logic to testing and verification of software and digital circuits that focuses on applications rather than theory. Computer scientists use logic for testing and verification of software and digital circuits, but many computer science students study logic only in the context of traditional mathematics, encountering the subject in a few lectures and a handful of problem sets in a discrete math course. This book offers a more substantive and rigorous approach to logic that focuses on applications in computer science. Topics covered include predicate logic, equation-based software, automated testing and theorem proving, and large-scale computation. Formalism is emphasized, and the book employs three formal notations: traditional algebraic formulas of propositional and predicate logic; digital circuit diagrams; and the widely used partially automated theorem prover, ACL2, which provides an accessible introduction to mechanized formalism. For readers who want to see formalization in action, the text presents examples using Proof Pad, a lightweight ACL2 environment. Readers will not become ALC2 experts, but will learn how mechanized logic can benefit software and hardware engineers. In addition, 180 exercises, some of them extremely challenging, offer opportunities for problem solving. There are no prerequisites beyond high school algebra. Programming experience is not required to understand the book's equation-based approach. The book can be used in undergraduate courses in logic for computer science and introduction to computer science and in math courses for computer science students.

An extraordinary journey to visit the oldest trees in the United States that beautifully reveals the connection between humans and natural history— a perfect read for nature lovers and fans of The Hidden Life of Trees. Follow award-winning author Anthony D. Fredericks's adventures across the United States to uncover the remarkable secrets and lives of ancient trees. He introduces some of the oldest trees in the country using up-to-date research, interviews with scientists, captivating storytelling, and a contagious wonder for the natural world. Fredericks's visits to the trees turn readers into fellow travelers. Through firsthand accounts and scientific detail, these enduring trees come to life off the page. Each chapter begins with a time-travel story that immerses readers in Earth's past, as early as ~58,000 BCE, for a sweeping view of what was happening during human history when the ancient tree took root. It then zooms into present-day to investigate the tree in all its mature glory and the changed world around it. Some of the featured trees include: A 13,000-year-old Palmer's oak in California that survives by cloning itself The 1,200-year-old Seven Sisters Oak in Louisiana that has survived in the path of at least ten major hurricanes 2,000-year-old redwoods (the tallest trees in the world) on the California coast The 2,628 year old bald cypress in the Black River of North Carolina Marvelously detailed and deeply passionate, In Search of the Old Ones will transform your perspective of the trees and forests around you.

Learn to identify the implementation of Discrete Structure and Theory of Automata in a myriad of applications used in day to day lifeKey Featuresa- Learn how to write an argument using logical notation and decide if the argument is valid or not valid.a- Learn how to use the concept of different data structures (stacks, queues, sorting concept, etc.) in the computer science field.a- Learn how to use Automata Machines like FSM, Pushdown automata, Turing machine, etc. in various applications related to computer science through suitable practical illustration.a- Learn how to implement the finite state machine using JFLAP (Java Formal Languages and Automata Package).DescriptionThis book's purpose is to provide a modern and comprehensive introduction to the subject of Discrete Structures and Automata Theory. Discrete structures, also called Discrete Mathematics, are an exciting and active subject, particularly due to its extreme relevance to both Mathematics and Computer Science and Algorithms. This subject forms a common foundation for rigorous Mathematical, Logical Reasoning and Proofs, as well as a formal introduction to abstract objects that are essential tools in an assortment of applications and effective computer implementations. Computing skills are now an integral part of almost all the Scientific fields, and students are very enthusiastic about being able to harness the full computing power of these tools. Further, this book also deep dives into the Automata Theory with various examples that illustrate the basic concepts and is substantiated with multiple diagrams. The book's vital feature is that it contains the practical implementation of the Automata Machine example through the JFLAP Tool. Courses on Discrete Structures and Automata theory are offered at most universities and colleges.What will you learna- Understand the basic concepts of Sets and operations in Sets.a- Demonstrate different traversal techniques for Trees and Graphs.a- Deep dive into the concept of Mathematical Induction, Sets, Relations, Functions, Recursion, Graphs, Trees, Boolean Algebra, and Proof techniques.a- Understand the concept of Automata Machines in day to day life like the Elevator, Turnstile, Genetic Algorithms, Traffic lights, etc.a- Use the JFLAP tool to solve the various exercise problems related to automata theory.Who this book is forThis book is a must-read to everyone interested in improving their concepts regarding Discrete Structure and Automata Theory.Table of Contents1.
