Book Description
Purpureae vestes estudia un element fonamental en la vida de qualsevol societat antiga com és el vestit i els colors utilitzats per a la seua ornamentació, especialment la púrpura. El luxe en el vestir implicava l'ús de materials com l'or per a la confecció de certs complements. Amb uns antecedents clarament orientals de recerca de la magnificència externa de reis i d'altres dignataris, el simbolisme del color en l'ornamentació personal va constituir, a les ciutats riberenques de la Mediterrània, un factor important de distinció social. Bé fossen de procedència vegetal, mineral o animal, els tints van donar sempre l'«ànima» als tèxtils. Per això, el poder imperial romà, en alguns períodes de la seua història, va controlar amb normes legals de major o menor duresa l'ús de determinats colors obtinguts a partir de gasteròpodes marins. L'obra tracta extensament els aspectes econòmics i tècnics relacionats amb l'elaboració i comercialització de vestits i teles per a altres usos (veles, adorns de la llar, etc.). A partir de diversos punts de vista, entre els que s'inclouen les dades arqueològiques o les referències etnograficocomparatives, s'hi incideix en les etapes de preparació de les fibres tèxtils, en les formes d'elaboració dels teixits més complexos a través de la reconstrucció experimental, en el treball dels pescadors i manufacturers que elaboraven en tallers costaners el tint més valorat, la púrpura, o en els qui treballaven en els tallers de la ciutat, així com en l'anàlisi i descripció detallada dels resultats extrets de les restes tèxtils aparegudes en jaciments, de l'Egipte romà sobretot, que ens mostren encara avui la riquesa i vivor dels seus colors.

Book Description
Payne's study places Spain's Second Republic within the historical framework of Spanish liberalism, and the rapid modernisation of inter-war Europe. He aims to present a consistent and detailed interpretation, demonstrating striking parallels to the German Weimar Republic.

Book Description
The material presented here corresponds to Fermi lectures that I was invited to deliver at the Scuola Normale di Pisa in the spring of 1998. The obstacle problem consists in studying the properties of minimizers of the Dirichlet integral in a domain D of Rn, among all those configurations u with prescribed boundary values and costrained to remain in D above a prescribed obstacle F. In the Hilbert space H1(D) of all those functions with square integrable gradient, we consider the closed convex set K of functions u with fixed boundary value and which are greater than F in D. There is a unique point in K minimizing the Dirichlet integral. That is called the solution to the obstacle problem.

Book Description
Higher Order Dynamic Mode Decomposition and Its Applications provides detailed background theory, as well as several fully explained applications from a range of industrial contexts to help readers understand and use this innovative algorithm. Data-driven modelling of complex systems is a rapidly evolving field, which has applications in domains including engineering, medical, biological, and physical sciences, where it is providing ground-breaking insights into complex systems that exhibit rich multi-scale phenomena in both time and space. Starting with an introductory summary of established order reduction techniques like POD, DEIM, Koopman, and DMD, this book proceeds to provide a detailed explanation of higher order DMD, and to explain its advantages over other methods. Technical details of how the HODMD can be applied to a range of industrial problems will help the reader decide how to use the method in the most appropriate way, along with example MATLAB codes and advice on how to analyse and present results. - Includes instructions for the implementation of the HODMD, MATLAB codes, and extended discussions of the algorithm - Includes descriptions of other order reduction techniques, and compares their strengths and weaknesses - Provides examples of applications involving complex flow fields, in contexts including aerospace engineering, geophysical flows, and wind turbine design

Book Description
Historical stone arch bridges are still a major part of the infrastructure in many countries. Although this type of bridge has proven to be an efficient construction type, it often poses the problem of insufficient numerical models of the load bearing behavior. Therefore the book introduces methods to adapt life loads and introduces different types of numerical models of the load resistance respectively. The book continues with the introduction of specific damages and strengthening techniques. The book particularly focuses on the probabilistic safety assessment of historical arch bridges, for which often only limited material and structural data is available.
