Fluid flows are characterized by uncertain inputs such as random initial data, material and flux coefficients, and boundary conditions. The current volume addresses the pertinent issue of efficiently computing the flow uncertainty, given this initial randomness. It collects seven original review articles that cover improved versions of the Monte Carlo method (the so-called multi-level Monte Carlo method (MLMC)), moment-based stochastic Galerkin methods and modified versions of the stochastic collocation methods that use adaptive stencil selection of the ENO-WENO type in both physical and stochastic space. The methods are also complemented by concrete applications such as flows around aerofoils and rockets, problems of aeroelasticity (fluid-structure interactions), and shallow water flows for propagating water waves. The wealth of numerical examples provide evidence on the suitability of each proposed method as well as comparisons of different approaches.

Revving engines, smoking tires, and high speeds. Car racing enthusiasts and race drivers alike know the thrill of competition, the push to perform better, and the agonyand dangersof bad decisions. But driving faster and better involves more than just high horsepower and tightly tuned engines. Physicist and amateur racer Chuck Edmondson thoroughly discusses the physics underlying car racing and explains just whats going on during any race, why, and how a driver can improve control and ultimately win. The world of motorsports is rich with excitement and competitionand physics. Edmondson applies common mathematical theories to real-world racing situations to reveal the secrets behind successful fast driving. He explains such key concepts as how to tune your car and why it matters, how to calculate 0 to 60 mph times and quarter-mile times and why they are important, and where, when, why, and how to use kinematics in road racing. He wraps it up with insight into the impact and benefit of green technologies in racing. In each case, Edmondsons in-depth explanations and worked equations link the physics principles to qualitative racing advice. From selecting shifting points to load transfer in car control and beyond, Fast Car Physics is the ideal source to consult before buckling up and cinching down the belts on your racing harness.

El anuncio del descubrimiento del largamente buscado bosón de Higgs, aunque podría no ser el predicho por la teoría, ha provocado un entusiasmo sin precedentes en la comunidad científica, entusiasmo que se ha contagiado a los medios de comunicacion y a la sociedad en general. Pero ¿Que es el boson de Higgs y porque tiene tanta importancia?, ¿Como se ha conseguido realizar ese descubrimiento y de que manera afecta a nuestras vidas? Este libro ofrece al lector las respuestas a estas preguntas y le permitira comprobar que, en efecto, el boson de Higgs ocupa un lugar clave en nuestra comprension del universo y revela secretos intimos de la naturaleza que tienen que ver con hecho muy basicos, tan basicos que a menudo ni siquiera pensamos sobre ellos, como son el vacio, la masa o la existencia de fuerzas electricas. Sin embargo, aunque esta particula sea clave en nuestra comprension del universo, tampoco lo explica todo. La naturaleza guarda misterios fascinantes que aun no han sido desvelados. Y de eso tambien trata este libro.

The Laser world consists basically of two areas, which are necessary and in many cases also sufficient for effective innovation: The right laser for the right application. For the individual application that means the determination of optimized process parameters in terms of laser power, peak power/ intensity, focus geometry and dimension, pulse length, pulse repetition rate and wavelength to name only the six most important ones. Once these parameters are identified, the corresponding Laser has to be selected on the basis of commercial availability. Obviously there is no such thing than ''One Laser for all''. The situation is rather comparable with electrical power, were depending on the demand of the application in terms of voltage, current and time corresponding power supplies need to be tailored, however, with the difference that in the case of the Laser the variety of parameters is even higher, thus the technology is more complex but on the other hand much more flexible in terms optimizing the source to the application. As a consequence it is suggested to generate two volumes on Lasers and Applications named "Tailored Light".

El relato del conocimiento del universo inabarcable, desde la mirada al cielo con el ojo desnudo hasta las sondas enviadas a años luz de la Tierra: una historia que tiene más de 3.600 años de antigüe

A series of seminal technological revolutions has led to a new generation of electronic devices miniaturized to such tiny scales where the strange laws of quantum physics come into play. There is no doubt that, unlike scientists and engineers of the past, technology leaders of the future will have to rely on quantum mechanics in their everyday work. This makes teaching and learning the subject of paramount importance for further progress. Mastering quantum physics is a very non-trivial task and its deep understanding can only be achieved through working out real-life problems and examples. It is notoriously difficult to come up with new quantum-mechanical problems that would be solvable with a pencil and paper, and within a finite amount of time. This book remarkably presents some 700+ original problems in quantum mechanics together with detailed solutions covering nearly 1000 pages on all aspects of quantum science. The material is largely new to the English-speaking audience. The problems have been collected over about 60 years, first by the lead author, the late Prof. Victor Galitski, Sr. Over the years, new problems were added and the material polished by Prof. Boris Karnakov. Finally, Prof. Victor Galitski, Jr., has extended the material with new problems particularly relevant to modern science.

Many new references reflect the expansion of this field. With examples from mammals, birds, reptiles, fish, amphibians, plants and invertebrates, this is an ideal introduction to conservation genetics for a broad audience. The text tackles the quantitative aspects of conservation genetics, and has a host of pedagogy to support students learning the numerical side of the subject. Combined with being up-to-date, its user-friendly writing style and first-class illustration programme forms a robust teaching package.

In the mathematical theory of viscous incompressible fluids the fundamental model is provided by the incompressible Navier-Stokes equations. For the last 20 years the analysis of the Navier-Stokes equations in the exterior of a moving and rotating obstacle has attracted particular attention. The main difficulty in this context arises from the fact that a linear coordinate transformation, which is used to handle the moving domain, results in transformed fluid equations that contain a drift term with linearly growing, hence unbounded coefficients. In this thesis the Navier-Stokes equations in the exterior of a moving, in particular rotating, obstacle are studied and the main emphasis is placed on the case where the obstacle undergoes a rotation described by a non-autonomous equation, and on fluids with variable density. In the non-autonomous case an appropriate functional analytic framework is adopted to show existence and uniqueness of local mild solutions. Moreover, based on the Faedo-Galerkin method and suitable a priori estimates, a well-posedness result for incompressible fluids with variable density is proved. For the proof new techniques needed to be developed. In particular, new elliptic estimates for the modified stationary Stokes problem with rotating effect are derived
