This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: El objetivo de este Proyecto Final de Grado es someter a estudio diferentes formulaciones de mortero, con la finalidad de observar como afecta el uso de adiciones y aditivos, a las propiedades físicas y mecánicas del cemento portland. Para poder llevar a cabo este análisis, se han realizado probetas de mortero utilizando dos tipos de cemento diferentes, un cemento portland sin adición y un cemento portland con un contenido de ceniza volante silícea, comprendido entre el 6% y el 20%. Para la parte estadística, se ha optado por la elaboración de un diseño de experimentos basado en la metodología de superficies de respuesta. Las técnicas de diseño de experimentos se basan en estudiar simultáneamente los efectos de todos los factores de interés. Esta metodología, frente a la forma tradicional de experimentación, que se basa en variar los niveles de un factor manteniendo fijos los restantes, presenta numerosas ventajas, ya que permite reducir considerablemente el número de pruebas a realizar y proporciona mejores resultados con un menor coste. Por lo tanto, se han desarrollado dos diseños de experimentos idénticos, uno para cada tipo de cemento. A través del diseño, se ha determinado el número de formulaciones y de réplicas de las mismas con las que posteriormente se experimentará. Los factores de influencia que varían son el agua y el aditivo y los que se mantienen fijos son el árido y el cemento. Por cada combinación indicada en el diseño, se han elaborado seis probetas, dos para ser ensayadas mecánicamente a los 7 días de edad, otras dos, a los 28 días de edad y las dos restantes, a los 90 días de edad. También se han llevado a cabo ensayos de consistencia y de densidad en fresco de cada una de las pastas de mortero amasadas. Para la caracterización mecánica, las probetas se han sometido a flexotracción simple con carga puntual centrada y, posteriormente, las mitades obtenidas a compresión. Finalmente se han introducido los resultados en el diseño y se han obtenido modelos que representan de forma gráfica y analítica el comportamiento mecánico de los cementos estudiados. Esto modelos permiten conocer la resistencia a compresión para cualquier combinación dentro del rango estudiado.

Download or read book The Code Book written by Simon Singh and published by Anchor. This book was released on 2000-08-29 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his first book since the bestselling Fermat's Enigma, Simon Singh offers the first sweeping history of encryption, tracing its evolution and revealing the dramatic effects codes have had on wars, nations, and individual lives. From Mary, Queen of Scots, trapped by her own code, to the Navajo Code Talkers who helped the Allies win World War II, to the incredible (and incredibly simple) logisitical breakthrough that made Internet commerce secure, The Code Book tells the story of the most powerful intellectual weapon ever known: secrecy. Throughout the text are clear technical and mathematical explanations, and portraits of the remarkable personalities who wrote and broke the world's most difficult codes. Accessible, compelling, and remarkably far-reaching, this book will forever alter your view of history and what drives it. It will also make you wonder how private that e-mail you just sent really is.

Available in PDF, EPUB and Kindle. Book excerpt: During the oil crisis of 1973, we suddenly became aware that fossil fuel resources are limited and will be exhausted soon if new alternatives are not put into use immediately. Conservation measures and extensive research on new sources of energy has eased the demand on fossil fuels, especially crude oil. Geothermal energy as an alternative; source had its share in this devel opment and electricity producing capacity increased from 700 to 4700 MWe during 1970 to 1985. Geothermal reservoir engineering emerged as an impor tant field in the assessment of geothermal sources. During the 25 years of its development, several areas were identified that needed further at tention for the correct description and interpretation of reservoir be havior. This fact as accepted by all operators is vital for the steady and continuous operation of power plants. During this NATO ASI, a detailed review of theory and field case his tories on geothermal reservoir engineering was presented. In understanding .the reservoir, conceptual models, natural state models, well bore measure ments, transient and tracer testing provide data which are indispensable. They are powerful tools in understanding reservoir behavior provided we know how to interpret them. During lectures the theory and practical applications of these interpretive methods were discussed.

Book excerpt: Today Bayt al-'Aqqad is one of 23 buildings in old Damascus which come under the UNESCO World Heritage programme, but when the Danish Institute in Damascus took over the house in 1997 it had been derelict for 50 years and was in a very sorry state indeed. In the following years Danish architects and restorers worked together with Syrian colleagues on an admirable restoration of the house. Step by step new aspects turned up, showing that the building was not only a beautiful house with a long history - the house is founded on the Roman theatre of Herod - but also that it contained fine examples of the most important periods in the architectural history of Damascus. In this lavishly illustrated book the story of the house and its resurrection is told by architects, restorers, archaeologists and historians and it is a must for anybody who has experienced the joy and fascination of Islamic art and architecture.
