Basic Rotordynamics: Introduction to Practical Vibration Analysis," this book is intended for all practical designers and maintenance experts who are responsible for the reliable manufacturing and operation of rotating machinery. It opens with the dynamics of oil film bearings and their influences on unbalance, vibration resonance and the stability of rotor whirl motion.

In closing, a 100-question trial test is supplied as an example of the certification of vibration experts based on the ISO standard.

The term active fluids refers to motions that are created by transforming energy from the surroundings into directed motion. There are many examples, both natural and synthetic, including individual swimming bacteria or motile cells, drops and bubbles that move owing to surface stresses (so-called Marangoni motions), and chemical- or optical-driven colloids. Investigations into active fluids provide new insights into non-equilibrium systems, have the potential for novel applications, and open new directions in physics, chemistry, biology and engineering. This book provides an expert introduction to active fluids systems, covering simple to complex environments. It explains the interplay of chemical processes and hydrodynamics, including the roles of mechanical and rheological properties across active fluids, with reference to experiments, theory, and simulations. These concepts are discussed for a variety of scenarios, such as the trajectories of microswimmers, cell crawling and fluid stirring, and apply to collective behaviours of dense suspensions and active gels. Emerging avenues of research are highlighted, ranging from the role of active processes for biological functions to programmable active materials, showcasing the exciting potential of this rapidly-evolving research field.

There is still room for research in computational contact mechanics, hence engineering analysis includes unilateral constraints when a detailed modelling of a problem is needed. Contact modelling within real structures includes e.g. rolling wheels, metal forming processes and car crash analysis, and is outcome of the increasing power of modern computers. Also, multi-physics modelling of thermo-mechanical or electro-mechanical contact and microscopic modelling are used in order to get a deeper insight into the mechanism of friction and wear. Moreover, new numerical simulation techniques were developed within the finite element or boundary element method yielding better discretization tools and more efficient algorithms for contact. However, up to now there exists no approach which solves all problems of the above mentioned areas in a robust and reliable way, hence investigations and developments are still needed. The aim of the symposium was to bring scientists together who work on the frontier of research in computational contact mechanics described above, or in closely related subjects. During the symposium 37 scientists presented their newest findings in the area of discretization techniques for contact, algorithms and interesting numerical simulations of contact problems. The symposium gave detailed insight in the newest development in the area of simulation techniques for contact problems. Topics treated included new mathematical techniques like multi-level approaches, new discretization techniques like the mortar-method, advanced applications of unilateral contact to masonry structures, decohesion analysis and tractive rolling of tires. The current volume provides a goodoverview of modern techniques and state-of-the-art discretizations schemes applied in contact mechanics, and will stimulate future collaboration in science related to computational contact mechanics and in the organization of minisymposia and workshops in the area contact mechanics.
