Zerspanung mit Eigenschmierstoff: Bearbeitung von Stahl mit geometrisch bestimmter Schneide optimieren (essentials)
by Egbert SchäpermeierDieses essentials behandelt einen neuen Ansatz zur effizienteren Zerspanung von Stählen: Bei der Spanbildung handelt es sich um einen Vorgang mit unvollkommener Ähnlichkeit. Die Ähnlichkeitsmechanik geht davon aus, dass sich nur vollkommene Vorgänge geschlossen analytisch darstellen lassen. Daher wird der wirtschaftlich interessante Bereich der Zerspanung abgegrenzt, welcher vollkommene Ähnlichkeit besitzt und für diesen Bereich erstmals die analytischen Grundlagen für Lehre, Studium, Forschung, Entwicklung und Fertigung zusammengestellt. Ergebnis ist eine Optimierung der Maschineneinstelldaten für eine wirtschaftlichere und ressourcenschonendere Produktion.
Zeroes
by Chuck WendigFive hackers--an Anonymous-style rabble-rouser, an Arab Spring hacktivist, a black-hat hacker, an old-school cipherpunk, and an online troll--are detained by the U.S. government, forced to work as white-hat hackers for Uncle Sam in order to avoid federal prison. At a secret complex known only as "the Lodge," where they will spend the next year working as an elite cyber-espionage team, these misfits dub themselves "the Zeroes."But once the Zeroes begin to work, they uncover secrets that would make even the most dedicated conspiracy theorist's head spin. And soon they're not just trying to serve their time, they're also trying to perform the ultimate hack: burrowing deep into the U.S. government from the inside, and hoping they'll get out alive. Packed with electric wit and breakneck plot twists, Zer0es is an unforgettable thrill ride through the seedy underbelly of "progress."they decide to turn the tables, will their own secrets be exposed--and their lives erased like lines of bad code?Combining the scientific-based, propulsive narrative style of Michael Crichton with the eerie atmosphere and conspiracy themes of The X-Files and the imaginative, speculative edge of Neal Stephenson and William Gibson, Zer0es explores our deep-seated fears about government surveillance and hacking in an inventive fast-paced novel sure to earn Chuck Wendig the widespread acclaim he deserves.
The Zero Waste Solution: Untrashing the Planet One Community at a Time
by Paul ConnettWaste is something we all make every day but often pay little attention to. That's changing, and model programs around the globe show the many different ways a community can strive for, and achieve, zero-waste status. Scientist-turned-activist Paul Connett, a leading international figure in decades-long battles to fight pollution, has championed efforts to curtail overconsumption and keep industrial toxins out of our air and drinking water and bodies. But he's best known around the world for leading efforts to help communities deal with their waste in sustainable ways-in other words, to eliminate and reuse waste rather than burn it or stow it away in landfills. In The Zero Waste Solution, Connett profiles the most successful zero-waste initiatives around the world, showing activists, planners, and entrepreneurs how to re-envision their community's waste-handling process-by consuming less, turning organic waste into compost, recycling, reusing other waste, demanding nonwasteful product design, and creating jobs and bringing community members together in the process. The book also exposes the greenwashing behind renewed efforts to promote waste incinerators as safe, nontoxic energy suppliers, and gives detailed information on how communities can battle incineration projects that, even at their best, emit dangerous particles into the atmosphere, many of which remain unregulated or poorly regulated. An important toolkit for anyone interested in creating sustainable communities, generating secure local jobs, and keeping toxic alternatives at bay.

Zero-Sustainment Aircraft for the U.S. Air Force
by National Research CouncilOverall Air Force weapon system sustainment (WSS) costs are growing at more than 4 percent per year, while budgets have remained essentially flat. The cost growth is due partly to aging of the aircraft fleet, and partly to the cost of supporting higher-performance aircraft and new capabilities provided by more complex and sophisticated systems, such as the latest intelligence, surveillance, and reconnaissance (ISR) platforms. Furthermore, the expectation for the foreseeable future is that sustainment budgets are likely to decrease, so that the gap between budgets and sustainment needs will likely continue to grow wider. Most observers accept that the Air Force will have to adopt new approaches to WSS if it is going to address this problem and remain capable of carrying out its missions. In this context, the original intent of this 3-day workshop was to focus on ways that science and technology (S&T) could help the Air Force reduce sustainment costs. However, as the workshop evolved, the discussions focused more and more on Air Force leadership, management authority, and culture as the more critical factors that need to change in order to solve sustainment problems. Many participants felt that while S&T investments could certainly help--particularly if applied in the early stages ("to the left") of the product life cycle--adopting a transformational management approach that defines the user-driven goals of the enterprise, empowers people to achieve them, and holds them accountable, down to the shop level. Several workshop participants urged Air Force leaders to start the process now, even though it will take years to percolate down through the entire organization. These sustainment concerns are not new and have been studied extensively, including recent reports from the National Research Council's Air Force Studies Board and the Air Force Scientific Advisory Board.
