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?

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.

Description This 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 learn _ Understand the basic concepts of Sets and operations in Sets. _ Demonstrate different traversal techniques for Trees and Graphs. _ Deep dive into the concept of Mathematical Induction, Sets, Relations, Functions, Recursion, Graphs, Trees, Boolean Algebra, and Proof techniques. _ Understand the concept of Automata Machines in day to day life like the Elevator, Turnstile, Genetic Algorithms, Traffic lights, etc. _ Use the JFLAP tool to solve the various exercise problems related to automata theory.

Hidden away in foggy, uncharted rain forest valleys in Northern California are the largest and tallest organisms the world has ever sustained–the coast redwood trees, Sequoia sempervirens. Ninety-six percent of the ancient redwood forests have been destroyed by logging, but the untouched fragments that remain are among the great wonders of nature. The biggest redwoods have trunks up to thirty feet wide and can rise more than thirty-five stories above the ground, forming cathedral-like structures in the air. Until recently, redwoods were thought to be virtually impossible to ascend, and the canopy at the tops of these majestic trees was undiscovered. In The Wild Trees, Richard Preston unfolds the spellbinding story of Steve Sillett, Marie Antoine, and the tiny group of daring botanists and amateur naturalists that found a lost world above California, a world that is dangerous, hauntingly beautiful, and unexplored. The canopy voyagers are young—just college students when they start their quest—and they share a passion for these trees, persevering in spite of sometimes crushing personal obstacles and failings. They take big risks, they ignore common wisdom (such as the notion that there’s nothing left to discover in North America), and they even make love in hammocks stretched between branches three hundred feet in the air. The deep redwood canopy is a vertical Eden filled with mosses, lichens, spotted salamanders, hanging gardens of ferns, and thickets of huckleberry bushes, all growing out of massive trunk systems that have fused and formed flying buttresses, sometimes carved into blackened chambers, hollowed out by fire, called “fire caves.” Thick layers of soil sitting on limbs harbor animal and plant life that is unknown to science. Humans move through the deep canopy suspended on ropes, far out of sight of the ground, knowing that the price of a small mistake can be a plunge to one’s death. Preston’s account of this amazing world, by turns terrifying, moving, and fascinating, is an adventure story told in novelistic detail by a master of nonfiction narrative. The author shares his protagonists’ passion for tall trees, and he mastered the techniques of tall-tree climbing to tell the story in The Wild Trees—the story of the fate of the world’s most splendid forests and of the imperiled biosphere itself.
