  • Annals of Mathematics This is the first in a series of papers whereby we combine the classical approach to exponential Diophantine equations (linear forms in logarithms, Thue equations, etc.) with a modular approach based on some of the ideas of the proof of Fermat’s Last Theorem. In this paper we give new improved bounds for linear forms in three logarithms. We also apply a combination of classical techniques with the modular approach to show that the only perfect powers in the Fibonacci sequence are 0, 1, 8 and 144 and the only perfect powers in the Lucas sequence are 1...

  • This book is about foundational issues in risk and risk analysis; how risk should be expressed; what the meaning of risk is; how to understand and use models; how to understand and address uncertainty; and how parametric probability models like the Poisson model should be understood and used. A unifying and holistic approach to risk and uncertainty is presented, for different applications and disciplines.

  • Functional Programming in C# leads you along a path that begins with the historic value of functional ideas. Inside, C# MVP and functional programming expert Oliver Sturm explains the details of relevant language features in C# and describes theory and practice of using functional techniques in C#, including currying, partial application, composition, memoization, and monads.

  • Every corner on a track has a maximum speed or limit at which it can be driven. Your ability to find the limits of your car and yourself will determine the speed at which you will be able to negotiate each turn. We will always be able to go fastest with our foot to the floor and the steering wheel pointed straight ahead. But, as we approach a turn and start turning the steering wheel, we slow down even if we have our foot to the floor! By turning, we have created a sideways load on...

  • A quantitative approach to studying human biomechanics, presenting principles of classical mechanics using case studies involving human movement. Vector algebra and vector differentiation are used to describe the motion of objects and 3D motion mechanics are treated in depth. Diagrams and software-created sequences are used to illustrate human movement.

  • This paper studies the problem of sentencelevel semantic coherence by answering SATstyle sentence completion questions. These questions test the ability of algorithms to distinguish sense from nonsense based on a variety of sentence-level phenomena. We tackle the problem with two approaches: methods that use local lexical information, such as the n-grams of a classical language model; and methods that evaluate global coherence, such as latent semantic analysis.

  • This paper describes a classical logic for attribute-value (or feature description) languages which ate used in urfification grammar to describe a certain kind of linguistic object commonly called attribute-value structure (or feature structure). Tile algorithm which is used for deciding satisfiability of a feature description is based on a restricted deductive closure construction for sets of literals (atomic formulas and negated atomic formulas). In contrast to the Kasper/Rounds approach (cf.

  • Thinking Skills are some of the most valuable skills you can learn today. The reason is simple. While in the past, people went to work for their manual skills, today they go to work for their mental skills. We live in an Information Age, no longer an Industrial Age. That’s why brain has replaced brawn, and strength in thinking has replaced strength in muscles. No matter what kind of business you work for, nor what kind of job you do, today you are expected to apply a range of thinking skills to the work you carry out. This includes using...

  • We all know someone who is incredibly bright and yet cannot seem to pull their life together. The brilliant student who flunks out of university, or the incredibly intelligent worker who can’t seem to get ahead in their company. We know from our familiarity with them that they have a good to superior intelligence level, but that doesn’t seem to be enough to ensure success. And at the same time, we can probably describe in some form why we feel these people have not been successful. Our descriptions would include certain traits or behaviors that have nothing to do with...

  • Central to this book are two ideas. The first is that Fluid Mechanics is relevant to a wide variety of problems that are priorities in the early 21st century, three of which are health, the environment, and energy. The second idea is that researchers in this field are applying novel methods to address these problems. Even on its most basic level, Fluid Mechanics is challenging.

  • Microbes produce an extraordinary array of microbial defense systems. These include broad-spectrum classical antibiotics, metabolic byproducts, such as the lactic acids produced by lactobacilli, lytic agents such as lysozymes, numerous types of protein exotoxins, and bacteriocins, which are loosely defined as biologically active protein moieties with a bacteriocidal mode of action.

  • With the introduction of genetic engineering of Escherichia coli by Cohen, Boyer and co-workers in 1973, the way was paved for a completely new approach to optimisation of existing biotech processes and development of completely new ones. This lead to new biotech processes for the production of recombinant proteins, e.g. the production of human insulin by a recombinant E. coli.

  • The current control problems present natural trend of increasing its complexity due to performance criteria that is becoming more sophisticated. The necessity of practicers and engineers in dealing with complex dynamic systems has motivated the design of controllers, whose structures are based on multiobjective constraints, knowledge from expert, uncertainties, nonlinearities, parameters that vary with time, time delay conditions, multivariable systems, and others.

  • This book, like its conventional counterpart Normal Findings in Radiography, deals with the apparently banal subject of the normal. It addresses the question of how to recognize what is normal and how to describe normal findings. These questions are as important in computed tomography and magnetic resonance imaging as in other modalities. Even “sectional imaging” is based on the classical approach of reading images and formulating findingPetrous pyramids

  • This book is intended to bridge a gap between the subject of classical vehicle dynamics and the general-purpose computer-based discipline known as multibody systems analysis (MBS). While there are several textbooks that focus entirely on the subject, and mathematical foundations, of vehicle dynamics and other more recent texts dealing with MBS, there are none yet that link the two subjects in a comprehensive manner.

  • Databases are encapsulated by business logic. Before the advent of stored-procedures, all the business logic ran in the transaction processing monitor which was the middle tier of the classic three- tier presentation-application-data architecture. With stored pro- cedures, the TP-monitors were disintermediated by two-tiered client/server architectures. The emergence of web-servers and HTTP brought three-tier architectures back to center stage – in part ...

  • Volcanism witnesses every major change of our planet and other planets. In Advances in Volcanology, scientists from highly active volcanic countries, such as Japan, Italy, and New Zealand, as well as others from Germany, Portugal, and Russia, debate less commonplace themes. Topics from classic field volcanology, including practical problems with volcanic stratigraphy in oil exploitation, to the most modern techniques related to tomographic studies are discussed.

  • Abstract. The classical Heron problem states: on a given straight line in the plane, find a point C such that the sum of the distances from C to the given points A and B is minimal. This problem can be solved using standard geometry or differential calculus. In the light of modern convex analysis, we are able to investigate more general versions of this problem. In this paper we propose and solve the following problem: on a given nonempty closed convex subset of Rs , find a point such that the sum of the distances from that point to n given nonempty closed convex subsets of...
