Análisis logarítmico lineal

This book presents conventions, mathematical concepts, definitions and applications central to the geometric modeling of solids, shells and wires (engineering jargon) embedded in 3D space. Currently, software is available for geometric modeling of technical or natural scenarios. However, the models built frequently fail in supporting the subsequent engineering computing and simulations. Only after repeated iterations and re-design, the models permit engineering / science simulations. This book endows the reader with the basic mathematical concepts needed to ensure that the geometric models...

A finales del siglo XX, año 1998, dos de los autores de este texto publicamos uno basado en la experiencia de impartir diversos cursos de Topología Diferencial en el Departamento de Geometría y Topología de la Facultad de Ciencias Matemáticas de la Universidad Complutense de Madrid. Se recogían en él las ideas centrales de transversalidad y aproximación en variedades con borde: los métodos que introdujo Thom a mediados del siglo XX, y que permiten hacer, en frase acuñada por Milnor «topología desde el punto de vista diferenciable». Efectivamente, producen de manera extremadamente ...

Pedro Nunes played a major part in the discovery of the world by Portuguese mariners. In this book, his mathematical and scientific achievements are described, together with evidence on his life and friends arising from a collection of his Greek and Latin poems, and from religious notes he composed during his later years. An English version of his long-lost Portuguese algebra is included, as well as poems and letters by his friends translated into English for the first time. These discoveries came from a manuscript recently found in the municipal library of Evora, the perfectly preserved...

One of the risks during pregnancy, with high negative impact on both pregnant and fetus, is cardiovascular disease suffering. Early diagnosis and proper treatment of this pathology significantly reduces the risk for pregnant. This problem is characterized by the insufficient availability of experts with knowledge of medical specialties involved, making it difficult to both the diagnosis process and the selection of appropriate treatment. In addition, in the treatment of this problem, there are situations of indetermination, uncertainty, vagueness, and incomplete data, hence the need to create ...
