VIBROACOUSTIC SIMULATION Learn to master the full range of vibroacoustic simulation using both SEA and hybrid FEM/SEA methods Vibroacoustic simulation is the discipline of modelling and predicting the acoustic waves and vibration of particular objects, systems, or structures. This is done through finite element methods (FEM) or statistical energy analysis (SEA) to cover the full frequency range. In the mid-frequency range, both methods must be combined into a hybrid FEM/SEA approach. By doing so, engineers can model full frequency vibroacoustic simulations in complex technical systems used in aircraft, trains, cars, ships, and satellites. Indeed, hybrid approaches are increasingly used in the automotive, aerospace, and rail industries. Previously covered primarily in scientific journals, Vibroacoustic Simulation provides a practical approach that helps readers master the full frequency range of vibroacoustic simulation. Through a systematic approach, the book illustrates why both FEM and SEA are necessary in acoustic engineering and how both can be used in combination through hybrid methodologies. Striking a crucial balance between complex theories and practical applications, the text provides real-world examples of vibroacoustic simulation, such as fuselage simulation, interior-noise prediction for electric and combustion vehicles, train profiles, and more, to help elucidate the concepts described within. Vibroacoustic Simulation also features: A balance of complex theories with the nuts and bolts of real-world applications Detailed worked examples of junction equations Case studies from companies like Audi and Airbus that illustrate how the methods discussed have been applied in real-world projects A companion website that provides corresponding Python codes for all examples, allowing readers to work through the examples on their own Vibroacoustic Simulation is a useful reference for acoustic and mechanical engineers working in the automotive, aerospace, defense, or rail industries, as well as researchers and graduate students studying acoustics.

This book documents what happens when people encounter public officials. It draws on multi-national Barometer surveys asking questions about corruption and bribery in 119 countries. Clear prose, tables and figures report the answers given by more than 250,000 people and the conclusion sets out six principles for reducing bribery.

While the Big Three and their continental Allies fought against Nazi Germany, another war was under way on the continent: the war to shape the political landscape of post-war Europe. In the Balkans, the war overlapped with political and ethnic conflicts, engulfing the region in bloody civil wars. In Central and Eastern Europe, partisan movements engaged the Germans without losing sight of the danger posed by the arrival of the Red Army. In France and in Italy, the adoption of the slogans of national liberation provided the communist parties with a formidable democratic legitimacy, which established them as key players in the political lives of their countries. The British and the Americans worked to stir up, support, control, and direct these resistance groups. London created the Special Operations Executive (SOE) and Washington the Office of Strategic Services (OSS), both of whom sent agents into occupied Europe to liaise directly with the guerilla groups. Through the Comintern, Moscow carefully coordinated the actions of the European communist parties with the foreign policy of the Soviet Union, which was acting for the first time as a key player in the arena of international relations. The forests and the mountains where the partisans were fighting the Germans soon became a major part of the proxy war that the Big Three waged to shift the post-war geopolitical balance in their favour. Looking for the first time at the Big Three in a comparative study and spanning Europe from Yugoslavia to Poland, from Greece to France and Italy, this book vividly depicts and sharply analyses how this proxy war shaped the history of the post-war settlement. In so doing, Piffer deftly connects high political histories with history from below, making the book important reading for all those interested in the history of the war and cold war, communism and Resistance, and diplomacy and intelligence.

1m Friihling 1988 erschien der erste Band der Korrespondenz von Johann Bernoulli mit Pierre Varignon, betreut durch Pierre Costabel und Jeanne Peiffer. P. Costabel erlebte noch das Erscheinen des ersten Bandes und den Beginn der Drucklegung des zweiten, ehe er dahingerafft wurde. Wir mochten hier ab drucken, was wir im letzten Jahresbericht des Kuratoriums der Otto Spiess Stiftung schrieben: -Les relations de l'Edition Bernoulli avec Pierre Costabel remontent a plus de 50 ans comme il s'est plu a Ie rappeler lui-meme dans Ie Au Lecteur sur lequel s'ouvre Ie premier volume de la correspondance echan gee par Pierre Varignon et Johann Bernoulli: "Le 23 aout 1939, un an apn!s la signature a Bale du contrat qui me liait a la Commission Bernoulli pour la correspondance de Jean I avec Pierre Varignon, Ie hasard me mit en presence d'Otto Spiess sur Ie quai d'une gare de Normandie. Nous changions de train l'un et l'autre, dans des directions opposees. Lui pour gagner St-Malo et poursuivre sa recherche des pa piers de Maupertuis, moi pour rejoindre mon poste d'officier de tir dans une batterie antiaerienne. Nous eumes seulement Ie temps de nous pro mettre fideIite. C'est dans Ie cadre de ces promesses qu'apn!s la guerre, Otto Spiess n'a cesse de me fournir informations et avis. " Malheureusement, la guerre allait survenir et P. Costabel etre fait prison nier jusqu'en 1945. Jugeant sa situation trop perilleuse pour conserver les precieux documents qui lui avaient He remis, P."

This book explains why the role of corruption varies greatly between public services, between people, between national systems of governance, and between measures of corruption. More than 1.8 billion people pay the price of bad government each year, by sending a bribe to a public official. In developing countries, corruption affects social services, such as health care and education, and law enforcement institutions, such as the police. When public officials do not act as bureaucrats delivering services by the book, people can try to get them by hook or by crook. The book's analysis draws on unique evidence: a data base of sample surveys of 175,000 people in 125 countries in Africa, Asia, the Middle East, Europe, and North and South America. The authors avoid one-size-fits-all proposals for reform and instead provide measures that can be applied to particular public services to reduce or eliminate opportunities for corruption.
