Verified Functional Programming in Agda (ACM Books)
ACM Books
£61.44
Agda is an advanced programming language based on Type Theory. Agda's type system is expressive enough to support full functional verification of programs, in two styles. In external verification, we write pure functional programs and then write proofs of properties about them. The proofs are separate external artifacts, typically using structural induction. In internal verification, we specify properties of programs through rich types for the programs themselves. This often necessitates including proofs inside code, to show the type checker that the specified properties hold. The power to prove properties of programs in these two styles is a profound addition to the practice of programming, giving programmers the power to guarantee the absence of bugs, and thus improve the quality of software more than previously possible. Verified Functional Programming in Agda is the first book to provide a systematic exposition of external and internal verification in Agda, suitable for undergraduate students of Computer Science. No familiarity with functional programming or computer-checked proofs is presupposed. The book begins with an introduction to functional programming through familiar examples like booleans, natural numbers, and lists, and techniques for external verification. Internal verification is considered through the examples of vectors, binary search trees, and Braun trees. More advanced material on type-level computation, explicit reasoning about termination, and normalization by evaluation is also included. The book also includes a medium-sized case study on Huffman encoding and decoding. Exercises are provided at the end of each chapter.

A global ice age... pushes humanity to the brink of extinction.As ice spreads across the planet, scientists race to figure out why the Earth is cooling.They send probes into space--and make a shocking discovery: there's a mysterious object drifting toward the sun.Could it save us from the ice age?Or is it the cause?With time running out, NASA launches a desperate mission to make contact with the object. But it isn't what they expected.* * * From A.G. Riddle, the worldwide bestselling author of The Atlantis Gene and Departure, comes a new sci-fi thriller that will change the way you look at Earth's place in the solar system forever.* * * Each month, Earth grows colder. Snow falls in summer. Glaciers trample cities across North America, Europe, and Asia. The new ice age gripping the planet shows no signs of stopping.Chaos erupts. Around the world, people abandon their homes, fleeing the cold, flocking to regions where they can survive.Nations prepare to go to war for the world's last habitable zones.NASA and other scientific organizations race to discover why the world is cooling. They send probes into the solar system to collect readings. Near Mars, one of the probes finds something no one expected: a mysterious object, drifting toward the sun. Could it be responsible for the new ice age? And if so, can we stop it? Or is the artifact merely an observer? Or neither? Could it be a relic from a long-extinct civilization? One thing is certain: investigating the artifact is humanity's best hope of survival.As the ice age claims more lives and the world slides into anarchy, an international consortium launches a mission into space to study the object and make contact. But the first contact mission doesn't go as planned. What the crew discovers out there is beyond anyone's imagination.Two members of the first contact mission may hold the keys to humanity's salvation.Dr. Emma Matthews is the commander aboard the International Space Station. For months, she has watched the world below freeze and civilization unravel. The headlines tell only half of the story. The messages from her sister tell the rest, of a world witnessing mass migrations, fighting for survival, struggling to provide a future for their children. When a catastrophe strikes the ISS, Emma faces her own fight for survival.Dr. James Sinclair is one of the greatest scientists alive. A mind before his time. Years ago, he invented something with the potential to change the world--an invention that would upset the balance of power in the world forever. Fearing that change, his enemies sent him to prison for a crime he didn't commit. But with humanity's future at stake, NASA asks him to join the first contact mission. His expertise is vital to the mission's success--and to saving Emma. With the clock ticking down to humanity's final days on Earth, James makes a decision that will change his life forever and may determine the fate of the entire human race.* * * Praise for A.G. Riddle "...reads like a superior collaboration between Dan Brown and Michael Crichton." -- The Guardian on Pandemic "I finished the book fast because I just couldn't wait..." -- WIRED GeekDad on Departure "Riddle... keep(s) the focus on his characters... rather than the technological marvels" -- Publisher's Weekly on Departure "Well-constructed and tightly-wound as a fine Swiss watch--DEPARTURE has non-stop action, an engaging plot and, of course, wheels within wheels." -- Diana Gabaldon, bestselling author of Outlander

It offers the unique gelling properties of Hydrofiber® technology with the power of ionic silver. The dressing fibres of AQUACEL® Ag gel on contact with wound fluid by hydrophilic action. The fibres swell as they lock bacterial exudate away from the wound by vertical wicking, creating a large fluid absorption capacity AQUACEL® Ag dressing can kill a broad spectrum of wound pathogens in the dressing that can cause infection including MRSA, VRE and Pseudomonas aeruginosa and aids in reducing the wound bioburden Bacteria and other harmful wound exudate components are locked within the gelled AQUACEL® Ag dressing fibres, where the ionic silver contained within the dressing kills them Application Before applying, carefully cleanse the wound with saline and dry surrounding skin. Apply directly onto the wound leaving an adequate overlap onto the surrounding skin of at least 1cm. When using AQUACEL® Ag dressing ribbon in cavity wounds, loosely pack wound to about 80% capacity leaving at least 2.5cm outside the wound for easy retrieval. The AQUACEL® Ag dressing should then be covered with an appropriate secondary wound care dressing. Clinical Benefits Supports moist wound healing environment Contains ionic silver which can kill a broad spectrum of wound pathogens that can cause infection - including MRSA, VRE and Pseudomonas aeruginosa Absorbs and retains higher levels of exudate than most alginates and gauze Reduces maceration by locking exudate into its fibres and away from the skin Cohesive gel allows easy, atraumatic removal Soft and conformable allowing intimate contact with the wound surface. This reduces "dead space" where bacteria may reside
