For decades, scientists and engineers have been working to increase the efficiency of internal combustion engines. For spark-ignition engines, two technical questions in particular are always in focus: 1. How can the air/fuel mixture be optimally ignited under all possible conditions? 2. How can undesirable but recurrent early and self-ignitions in the air/fuel mixture be avoided? Against the background of the considerable efficiency increases currently being sought in the context of developments and the introduction of new fuels, such as hydrogen, methanol, ammonia and other hydrogen derivatives as well as biofuels, these questions are more in the focus than ever. In order to provide a perfect exchange platform for the community of combustion process and system developers from research and development, IAV has organized this combined conference, chaired by Marc Sens. The proceedings presented here represent the collection of all the topics presented at the event and are thus intended to serve as an inspiration and pool of ideas for all interested parties.
"Are there common phenomena and laws in the dynamic behavior of granular materials, traffic, and socio-economic systems?" The answers given at the international workshop "Traffic and Granular Flow '99" are presented in this volume. From a physical standpoint, all these systems can be treated as (self)-driven many-particle systems with strong fluctuations, showing multistability, phase transitions, non-linear waves, etc. The great interest in these systems is due to several unexpected new discoveries and their practical relevance for solving some fundamental problems of today's societies. This includes intelligent measures for traffic flow optimization and methods from "econophysics" for stabilizing (stock) markets.
The book includes the papers presented at the conference discussing approaches to prevent or reliably control knocking and other irregular combustion events. The majority of today’s highly efficient gasoline engines utilize downsizing. High mean pressures produce increased knocking, which frequently results in a reduction in the compression ratio at high specific powers. Beyond this, the phenomenon of pre-ignition has been linked to the rise in specific power in gasoline engines for many years. Charge-diluted concepts with high compression cause extreme knocking, potentially leading to catastrophic failure. The introduction of RDE legislation this year will further grow the requirements for combustion process development, as residual gas scavenging and enrichment to improve the knock limit will be legally restricted despite no relaxation of the need to reach the main center of heat release as early as possible. New solutions in thermodynamics and control engineering are urgently needed to further increase the efficiency of gasoline engines.
This seminal compendium, available through open access, illuminates the forefront of digital collaboration in production. It introduces the visionary concept of the Internet of Production (IoP), an ambitious initiative by Germany's esteemed Cluster of Excellence at RWTH Aachen University. This handbook pioneers the integration of data, models, and knowledge across development, production, and user cycles, offering interdisciplinary insights into production technology's horizons with the overall objective to create a worldwide lab. The work is organized into seven key parts, each contributing to a comprehensive understanding of the IoP. Part I lays the foundation with interdisciplinary vision...
This book offers an insider's view of how industrial problems are translated into mathematics and how solving the mathematics leads to convincing industrial solutions as well. In 6 technical chapters, a wide range of industrial problems is modeled, simulated, and optimized; 4 others describe the modeling, computing, optimization, and data analysis concepts shaping the work of the Fraunhofer ITWM. Each technical chapter illustrates how the relevant mathematics has been adapted or extended for the specific application and details the underlying practical problem and resulting software. The final chapter shows how the use of mathematical modeling in the classroom can change the image of this subject, making it exciting and fun.
Gunter Anders' Philosophy of Technology is the first comprehensive exploration of the ground-breaking work of German thinker Gunter Anders. Anders' philosophy has become increasingly prescient in our digitised, technological age as his work predicts the prevalence of social media, ubiquitous surveillance and the turn to big data. Anders' ouevre also explored the technologies of nuclear power and the biotech concerns for the human and transhuman condition which have become so central to current theory. Babette Babich argues that Anders offers important resources on streaming digital media through his writings on radio, television and film and is, unusually, both a comprehensive and profound thinker. Anders' relationship with key philosophers like Hannah Arendt and Walter Benjamin and his thinking on Goethe, Nietzsche and Rilke is also explored with a focus on the deep impact he made on his peers. It reflects specifically on the intersection of Anders' thought Heidegger and the Frankfurt school and how influential a figure he was on the landscape of 20th century philosophy. A compelling rehabilitation of a thinker with profound contemporary relevance.
Was ist PR? Wer braucht PR? Welche Risiken und Nebenwirkungen hat PR? Neben einer kritischen Bilanz der aktuellen theoretischen Beiträge und der andauernden Kontroverse zwischen system- und handlungstheoretischen Ansätzen sollen zudem alternative theoretische Bezugsrahmen vorgestellt werden und neue Wege zu PR-Theorien aufgezeigt werden.
THE FIRST NOVEL IN PHILIP KERR’S ACCLAIMED HISTORICAL MYSTERY SERIES When private investigator Bernie Gunther agrees to track down some stolen jewels, his search takes him down the dangerous streets of pre-World War 2 Berlin and into the path of the most influential players in Nazi Germany… Wisecracking cop turned private investigator Bernie Gunther specializes in missing persons, and as the Third Reich’s power has grown, Bernie has become a very busy man. But as he takes on cases involving millionaire industrialists, stolen diamonds, and Hitler’s most powerful cronies, Bernie finds himself mired in the brutality and corruption of a country on the brink of war. Hard-hitting, fast-paced, and richly detailed, March Violets is noir writing at its blackest and best.

DIVDIVCassandra Reilly travels to Venice to solve the mystery of a missing bassoon, and lands in the midst of an international cast of characters who all have something to hide/divDIV At the Venice-based symposium on women musicians of Vivaldi’s time, an instrument has gone missing: an antique bassoon, an invaluable family heirloom—and bassoonist Nicky Gibbons stands accused of the theft. Determined to clear her name, Nicky calls Cassandra Reilly—lesbian translator and part-time sleuth extraordinaire—and summons her to the City of Water. Fifteen scholars and musicians are attending the symposium, and each has a multitude of quirks and secrets—as well as motive to steal the bassoon. As Cassandra investigates, she immerses herself in the world of Baroque music, the tangle of personal intrigues at the symposium, and a second mystery involving the orphaned bassoonists of eighteenth-century Venice./divDIV Wry, intelligent, and atmospheric, The Case of the Orphaned Bassoonists is the fourth and final book in the Cassandra Reilly Mystery series, which begins with Gaudí Afternoon, Trouble in Transylvania, and The Death of a Much-Travelled Woman./divDIV/div/div
