Prototype Nation: China and the Contested Promise of Innovation (Princeton Studies in Culture and Technology #29)
by Silvia M. LindtnerA vivid look at China’s shifting place in the global political economy of technology production How did China’s mass manufacturing and “copycat” production become transformed, in the global tech imagination, from something holding the nation back to one of its key assets? Prototype Nation offers a rich transnational analysis of how the promise of democratized innovation and entrepreneurial life has shaped China’s governance and global image. With historical precision and ethnographic detail, Silvia Lindtner reveals how a growing distrust in Western models of progress and development, including Silicon Valley and the tech industry after the financial crisis of 2007–8, shaped the rise of the global maker movement and the vision of China as a “new frontier” of innovation.Lindtner’s investigations draw on more than a decade of research in experimental work spaces—makerspaces, coworking spaces, innovation hubs, hackathons, and startup weekends—in China, the United States, Africa, Europe, Taiwan, and Singapore, as well as in key sites of technology investment and industrial production—tech incubators, corporate offices, and factories. She examines how the ideals of the maker movement, to intervene in social and economic structures, served the technopolitical project of prototyping a “new” optimistic, assertive, and global China. In doing so, Lindtner demonstrates that entrepreneurial living influences governance, education, policy, investment, and urban redesign in ways that normalize the persistence of sexism, racism, colonialism, and labor exploitation.Prototype Nation shows that by attending to the bodies and sites that nurture entrepreneurial life, technology can be extricated from the seemingly endless cycle of promise and violence.Cover image: Courtesy of Cao Fei, Vitamin Creative Space and Sprüth Magers

Prototyping of Concurrent Control Systems Implemented in FPGA Devices
by Remigiusz WiśniewskiThis book focuses on prototyping aspects of concurrent control systems and their further implementation and partial reconfiguration in programmable devices. Further, it lays out a full prototyping flow for concurrent control systems. Based on a given primary specification, a system is described with an interpreted Petri net, which naturally reflects the concurrent and sequential relationships of the design. The book shows that, apart from the traditional option of static configuration of the entire system, the latest programmable devices (especially FPGAs) offer far more sophistication. Partial reconfiguration allows selected parts of the system to be replaced without having to reprogram the entire structure of the device. Approaches to dynamic and static partial reconfiguration of concurrent control systems are presented and described in detail. The theoretical work is illustrated by examples drawn from various applications, with a milling machine and a traffic-light controller highlighted as representative interpreted Petri nets. Given the ubiquity of concurrent control systems in a huge variety of technological areas including transportation, medicine, artificial intelligence, manufacturing, security and safety and planetary exploration, the innovative software and hardware design methods described here will be of considerable interest to control engineers and systems and circuits researchers in many areas of industry and academia.
Prototyping of User Interfaces for Mobile Applications (T-Labs Series in Telecommunication Services)

Providing Safe Drinking Water in Small Systems: Technology, Operations, and Economics
by Joseph A. Cotruvo, Gunther F. Craun and Nancy HearneThe continued lack of access to adequate amounts of safe drinking water is one of the primary causes of infant morbidity and mortality worldwide and a serious situation which governments, international agencies and private organizations are striving to alleviate. Barriers to providing safe drinking water for rural areas and small communities that must be overcome include the financing and stability of small systems, their operation, and appropriate, cost-effective technologies to treat and deliver water to consumers.While we know how to technically produce safe drinking water, we are not always able to achieve sustainable safe water supplies for small systems in developed and developing countries. Everyone wants to move rapidly to reach the goal of universal safe drinking water, because safe water is the most fundamental essential element for personal and social health and welfare. Without safe water and a safe environment, sustained personal economic and cultural development is impossible. Often small rural systems are the last in the opportunity line.Safe Drinking Water in Small Systems describes feasible technologies, operating procedures, management, and financing opportunities to alleviate problems faced by small water systems in both developed and developing countries. In addition to widely used traditional technologies this reference presents emerging technologies and non-traditional approaches to water treatment, management, sources of energy, and the delivery of safe water.
Proving Ground: The Untold Story of the Six Women Who Programmed the World’s First Modern Computer
by Kathy KleimanDiscover a fascinating look into the lives of six historic trailblazers in this World War II-era story of the American women who programmed the world's first modern computer. After the end of World War II, the race for technological supremacy sped on. Top-secret research into ballistics and computing, begun during the war to aid those on the front lines, continued across the United States as engineers and programmers rushed to complete their confidential assignments. Among them were six pioneering women, tasked with figuring out how to program the world's first general-purpose, programmable, all-electronic computer—better known as the ENIAC—even though there were no instruction codes or programming languages in existence. While most students of computer history are aware of this innovative machine, the great contributions of the women who programmed it were never told—until now. Over the course of a decade, Kathy Kleiman met with four of the original six ENIAC Programmers and recorded extensive interviews with the women about their work. Proving Ground restores these women to their rightful place as technological revolutionaries. As the tech world continues to struggle with gender imbalance and its far-reaching consequences, the story of the ENIAC Programmers' groundbreaking work is more urgently necessary than ever before, and Proving Ground is the celebration they deserve.
Proxies: The Cultural Work of Standing In (Infrastructures)
by Dylan MulvinHow those with the power to design technology, in the very moment of design, are allowed to imagine who is included--and who is excluded--in the future.Our world is built on an array of standards we are compelled to share. In Proxies, Dylan Mulvin examines how we arrive at those standards, asking, "To whom and to what do we delegate the power to stand in for the world?" Mulvin shows how those with the power to design technology, in the very moment of design, are allowed to imagine who is included--and who is excluded--in the future.For designers of technology, some bits of the world end up standing in for other bits, standards with which they build and calibrate. These "proxies" carry specific values, even as they disappear from view. Mulvin explores the ways technologies, standards, and infrastructures inescapably reflect the cultural milieus of their bureaucratic homes. Drawing on archival research, he investigates some of the basic building-blocks of our shared infrastructures. He tells the history of technology through the labor and communal practices of, among others, the people who clean kilograms to make the metric system run, the women who pose as test images, and the actors who embody disease and disability for medical students. Each case maps the ways standards and infrastructure rely on prototypical ideas of whiteness, able-bodiedness, and purity to control and contain the messiness of reality. Standards and infrastructures, Mulvin argues, shape and distort the possibilities of representation, the meaning of difference, and the levers of change and social justice.

Prozess- und Anlagensicherheit
by Ulrich HauptmannsStörfälle in technischen Anlagen sind Zufallsereignisse. Deshalb kann man sie nicht gänzlich vermeiden. Wohl aber lassen sich die Wahrscheinlichkeit ihres Auftretens und das Schadensausmaß verringern. In diesem Buch werden, ausgehend von Gefährdungen durch Stoffe und Betriebsbedingungen, mögliche technische und organisatorische Maßnahmen aufgezeigt, Gefährdungen zu mindern. Qualitative Analysemethoden zum Auffinden von Schwachstellen und zur Erhöhung der Sicherheit sowie Modelle zur Abschätzung von Störfallfolgen werden dargestellt. Die quantitative Bewertung der Wirksamkeit von Maßnahmen zur Verbesserung von Anlagentechnik und Sicherheit wird erläutert. Dabei spielen Unsicherheiten, die aus dem Zufallscharakter des Störfalls und aus Kenntnislücken bei einigen der zu behandelnden Phänomene folgen, eine Rolle. Der Leser wird mit Methoden der Störfallsimulation sowie Sicherheits- und Risikoanalysen vertraut gemacht und lernt, Möglichkeiten und Grenzen mathematischer Modellierung einzuschätzen. Als Grundlage sicherheitsrelevanter Entscheidungen wird die Risikoermittlung u.a. auf die Beurteilung der „funktionalen Sicherheit“ und die Bestimmung „angemessener Sicherheitsabstände“ zwischen Industrie und Bebauung angewandt. Zahlreiche ausgearbeitete Beispiele und Fallstudien realer Anlagen und Situationen vertiefen die Inhalte und erleichtern das Selbststudium.Die zweite Auflage des vorliegenden Buches eröffnete die Möglichkeit, den Text gründlich durchzusehen und eine Reihe von Korrekturen vorzunehmen. Zusätzliche Beispiele, die sich aus Anfragen aus der Praxis ergaben, wurden aufgenommen. Das Kapitel über „angemessene Sicherheitsabstände“ wurde um aktuelle Erfahrungen aus der Beratertätigkeit des Verfassers erweitert.
Prozesse in Industriebetrieben mittels Low-Code-Software digitalisieren: Ein Praxisleitfaden (Intelligente Technische Systeme – Lösungen aus dem Spitzencluster it’s OWL)
by Stefan Sauer Sven Hinrichsen Klaus SchröderIn vielen Unternehmen besteht ein steigender Bedarf an betriebsspezifisch gestalteten Softwareanwendungen, um Geschäftsprozesse zu digitalisieren und zu optimieren. Derzeit sind vor allem IT-Fachkräfte gefordert, diese Anwendungen zu entwickeln. Da in Betrieben vielfach ein Mangel an IT-Fachkräften besteht, ist diese Vorgehensweise zumeist mit langen Bereitstellungszeiten verbunden. Durch die Nutzung der Low-Code-Programmierung ist es hingegen möglich, Softwareanwendungen ohne tiefe Programmierkenntnisse mittels einer grafischen Benutzeroberfläche zu erstellen. Der Vorteil: Es können passgenaue Lösungen in kurzer Zeit entwickelt werden, indem sich Beschäftigte aus Fachabteilungen mit ihrem Expertenwissen direkt an der Softwareentwicklung beteiligen. Allerdings fehlt es in vielen Betrieben an Wissen zu den Anwendungsmöglichkeiten und -grenzen dieser Art der Programmierung. Zudem ist es derzeit für potenzielle Anwender oftmals unklar, wie eine anforderungsgerechte Low-Code-Plattform ausgewählt und eingeführt werden kann. In diesem Buch werden daher die Herausforderungen bei der Einführung von Low-Code-Plattformen erörtert und umfangreiche Gestaltungsempfehlungen vermittelt, damit es Betrieben gelingt, die wirtschaftlichen Potenziale der Low-Code-Programmierung zu nutzen.
Prozessoptimierung bei Industrie 4.0 durch Risikoanalysen: Gefährdungen Erkennen Und Minimieren
by Bernd EbertDas Buch beschreibt die Methodik der Risikoanalyse bei der Umsetzung von Industrie 4.0. Durch diese Methode können strukturelle und Schnittstellen-Probleme in vernetzten Systemen frühzeitig erkannt und geeignete Gegenmaßnahmen getroffen werden. Die theoretischen Ansätze zu Industrie 4.0 werden in 3 Betrachtungs-Ebenen gegliedert. Für jede dieser Ebenen werden die Spezifika beschrieben und mittels Risikoanalyse bewertet. Werden Risiken erkannt, folgen Vorschläge zu deren Minimierung. Neben den exakt definierbaren Stückgut-Prozessen (z.B. im Automotive-Bereich) ist eine Betrachtung z.B. von losen Mengen (wie eingesetzte Chemikalien) erforderlich. Da die Einführung von Industrie 4.0 nicht global schlagartig erfolgen wird, sind die zeitliche Abfolge der Einführung sowie Zwischenstufen bzgl. ihrer Risiken sowie deren Minimierung zu betrachten.Die ZielgruppenDas Buch wendet sich an Planungsingenieure für technische Systeme, MSR-Ingenieure, Softwareplaner, Begutachter für Prozess- und Anlagensicherheit und an Verantwortliche für technische Innovationen.
