Many Flex books cover the basicsthis book does something different, and goes far further. The authors, leading Flash platform developers at Almer/Blank, working with Adobe User Group communities, are the creators of the Rich Media Exchange (RMX), a social media network for Adobe developers. In covering just how the RMX was built, this book contains all the knowledge you need to build similar large-scale rich Internet applications with Adobe Flex.

From the inception of the idea through to deployment, the authors show the techniques needed to plan and build advanced applications. You'll learn how to use forms, styles, validators, video, sound analysis, and framework caching, ensuring you make the most of the features introduced in Flex 3.

Powerful applications require solid back ends. This book shows how to hook up a Flex application to PHP back-end systems such as Drupal and OpenAds. You'll learn how various parts of the RMX were built, including the blogs, event calendar, jobs board, and advertising systemelements that come together to really showcase the power of Flex.

The RMX is built by Adobe developers for Adobe developersa rewarding community relationship that guarantees results. The same spirit is carried into this book, with the authors wanting and helping to take you to the next level of Flash application development.

Biomedical Innovations to Combat COVID-19 provides an updated overview on the development of vaccines, antiviral drugs and nanomaterials, and diagnostic methods for the fight against COVID-19. Perspectives on such technologies are identified, discussed, and enriched with figures for easy understanding and applicability. Furthermore, it contains basic aspects of virology, immunology, and antiviral drugs that are needed to fully appreciate these innovations. This book is split into four sections: introduction, presenting basic virologic and epidemiological aspects of COVID-19; vaccines against COVID-19, discussing their different types and applications used to develop them; diagnostic approaches for SARS-CoV-2, encompassing advanced sensing and microfluidic-based biosensors; and drug development and delivery, where antivirals based on nanomaterials or drugs are presented. It is a valuable source for virologists, biotechnologists, and members of biomedical field interested in learning more about how novel technologies can be applied to fasten the eradication of the COVID-19 and similar pandemics.

En el presente trabajo se analiza el problema de estabilizacion robusta de un sistema no lineal afin con incertidumbres acotadas de acuerdo a condiciones "Cuasi-Lipschitz" y salida medible sujeta a perturbaciones acotadas por elipsoides, utilizando una extension del metodo clasico del elipsoide invariante. El metodo del elipsoide invariante se basa en el segundo metodo de Lyapunov y el concepto de conjuntos invariantes. La solucion a este problema es expresada en terminos de un problema de optimizacion, cuya solucion esta sujeta a restricciones del tipo de Desigualdades Matriciales Lineales (LMI por sus siglas en ingles), considerando un metodo numerico efectivo para el diseno del correspondiente control por retroalimentacion. Los ejemplos numericos presentados muestran la efectividad del metodo propuesto, comparando el resultado con una tecnica convencional."
