In mathematics, the quaternions are a number system that extends the complex numbers. They were first described by Irish mathematician William Rowan Hamilton in 1843 and applied to mechanics in three-dimensional space. A feature of quaternions is that multiplication of two quaternions is noncommutative. Hamilton defined a quaternion as the quotient of two directed lines in a three-dimensional space or equivalently as the quotient of two vectors. Quaternions find uses in both theoretical and applied mathematics, in particular for calculations involving three-dimensional rotations such as in three-dimensional computer graphics, computer vision and crystallographic texture analysis. In practical applications, they can be used alongside other methods, such as Euler angles and rotation matrices, or as an alternative to them, depending on the application. (Wikipedia) As a first rough draft that has been put together very quickly, this book is likely to contain errata and disorganization. The references list and inline citations are very incompete, so the reader should search around for more references. I do not claim to be the inventor of any of the mathematics found here. However, some parts of this book may be considered new in some sense and were in small parts my own original research. Much of the contents was originally written by me as contributions to a web encyclopedia project just for fun, but for various reasons was inappropriate in an encyclopedic volume. I did not originally intend to write this book. This is not a dissertation, nor did its development receive any funding or proper peer review.

These notes present principles and applications of static analysis of programs. We cover type analysis, lattice theory, control flow graphs, dataflow analysis, fixed-point algorithms, narrowing and widening, interprocedural analysis, control flow analysis, and pointer analysis. A tiny imperative programming language with heap pointers and function pointers is subjected to numerous different static analyses illustrating the techniques that are presented. The style of presentation is intended to be precise but not overly formal. The readers are assumed to be familiar with advanced programming language concepts and the basics of compiler construction.

Today, in many spheres of human activity, massive sets of data are collected and stored. As the volumes of data available to lawmakers, civil servants, business people and scientists increase, their effective use becomes more challenging. Keeping up to date with the flood of data, using standard tools for data management and analysis, is fraught with difficulty. The field of visual analytics seeks to provide people with better and more effective ways to understand and analyse these large datasets, while also enabling them to act upon their findings immediately, in real-time. Visual analytics integrates the analytic capabilities of the computer and the abilities of the human analyst, thus allowing novel discoveries and empowering individuals to take control of the analytical process. Visual analytics sheds light on unexpected and hidden insights, which may lead to beneficial and profitable innovation. This book is one of the outcomes of a two-year project called VisMaster CA, a coordination action funded by the European Commission from August 2008 to September 2010. The goal of VisMaster was to join European academic and industrial R&D excellence from several individual disciplines, forming a strong visual analytics research community. An array of thematic working groups was set up by the consortium, which focused on advancing the state of the art in visual analytics. These working groups joined research excellence in the fields of data management, data analysis, spatial-temporal data, and human visual perception research with the wider visualisation research community.

We have all heard of the success story of the discovery of a link between the mental problems of children and the chemical pollutants in their drinking water. Similarly, we have heard of the 1854 Broad Street cholera outbreak in London, and the linking of it to a contaminated public water pump. These are two highprofile examples of bisociation, the combination of information from two different sources. This is exactly the focus of the BISON project and this book. Instead of attempting to keep up with the meaningful annotation of the data floods we are facing, the BISON group pursued a network-based integration of various types of data repositories and the development of new ways to analyze and explore the resulting gigantic information networks. Instead of finding well-defined global or local patterns they wanted to find domain-bridging associations which are, by definition, not well defined since they will be especially interesting if they are sparse and have not been encountered before. The present volume now collects the highlights of the BISON project. Not only did the consortium succeed in formalizing the concept of bisociation and proposing a number of types of bisociation and measures to rank their“bisociativeness,” but they also developed a series of new algorithms, and extended several of the existing algorithms, to find bisociation in large bisociative information networks. From a personal point of view, I was delighted to see that some of our own work on finding structurally similar pieces in large networks actually fit into that framework very well: Random walks, and related diffusion-based methods, can help find correlated nodes in bisociative networks. The concept of bisociative knowledge discovery formalizes an aspect of data mining that people have been aware of to some degree but were unable to formally pin down. The present volume serves as a great basis for future work in this direction.

Un trabajo académico es un discurso, por lo común escrito, concebido para transmitir conocimientos en el ámbito científico o universitario. En términos estrictos, supone la aplicación rigurosa de un método científicamente establecido y se asocia a largas tareas de investigación que son presentadas ante el tribunal evaluador de una institución o revista científica. En términos más generales, es la presentación que realiza un estudiante, tesista o investigador a fin de demostrar competencias en un área del conocimiento y de persuadir a un determinado receptor (docente, comité, jurado, entidad científica, etc.) de que cuenta con el entendimiento y la capacidad reflexiva suficientes dado el nivel académico en que se sitúa.

Topological K–theory, the first generalized cohomology theory to be studied thoroughly, was introduced around 1960 by Atiyah and Hirzebruch, based on the Periodicity Theorem of Bott proved just a few years earlier. In some respects K–theory is more elementary than classical homology and cohomology, and it is also more powerful for certain purposes. Some of the best-known applications of algebraic topology in the twentieth century, such as the theorem of Bott and Milnor that there are no division algebras after the Cayley octonions, or Adams’ theorem determining the maximum number of linearly independent tangent vector fields on a sphere of arbitrary dimension, have relatively elementary proofs using K–theory, much simpler than the original proofs using ordinary homology and cohomology. The first portion of this book takes these theorems as its goals, with an exposition that should be accessible to bright undergraduates familiar with standard material in undergraduate courses in linear algebra, abstract algebra, and topology. Later chapters of the book assume more, approximately the contents of a standard graduate course in algebraic topology. A concrete goal of the later chapters is to tell the full story on the stable J–homomorphism, which gives the first level of depth in the stable homotopy groups of spheres. Along the way various other topics related to vector bundles that are of interest independent of K–theory are also developed, such as the characteristic classes associated to the names Stiefel and Whitney, Chern, and Pontryagin.

Las creaciones artísticas y el derecho de autor” es la segunda publicación de la serie de la OMPI Aprender del pasado para crear el futuro, dirigida a jóvenes estudiantes. Esta serie se lanzó al reconocer la importancia de los niños y jóvenes como creadores del futuro. La publicación empieza con una breve explicación sobre la importancia del arte y el potencial de los jóvenes para llegar un día a ser grandes autores. El propósito de esta última entrega de la serie es animar a los jóvenes a usar su imaginación, su flexibilidad y las distintas facetas de su capacidad de expresión artística para crear obras de arte originales. Además, las secciones dedicadas a jóvenes autores que aparecen a lo largo de la publicación animan a los lectores, enseñándoles cómo otros jóvenes están creando obras y utilizando el derecho de autor para protegerlas. La principal parte de la publicación ofrece información básica sobre el derecho de autor y los derechos conexos. Después aparece una sección en la que se enseña a los estudiantes cómo pueden encontrar y utilizar obras que se hallen en el dominio público.
