Sommario/riassunto |
|
En este libro se presenta una reflexión sobre los riesgos a los cuales está expuesto el Distrito Metropolitano de Quito —DMQ— considerando la cuestión de la movilidad cotidiana de las personas y la accesibilidad, enmarcándose dentro de la filosofía de investigación planteada en el programa “Sistema de información y riesgos en el DMQ”, en el marco del convenio de la Dirección Metropolitana de Planificación Territorial y el Institut de Recherche pour le Développment (IRD, ex ORSTOM). En una primera parte se analizan los flujos y movimientos de personas y el sistema de transporte vigente. En una segunda parte se identifican y localizan las infraestructuras clave de la movilidad. A continuación se analizan los factores de vulnerabilidad de estas infraestructuras y finalmente, se abordan los riesgos a los cuales está expuesto el Distrito considerando un cierre de las vías clave lo que provocaría una reducción de la accesibilidad de los diferentes espacios metropolitanos. Esta publicación está dirigida a los planificadores urbanos, especialmente a los encargados del manejo del transporte o riesgos y de manera general a todos los ciudadanos interesados en comprender el funcionamiento de la movilidad de las personas y la vulnerabilidad del DMQ. |

Sommario/riassunto |
|
This book deals concisely and coherently with various issues related to electroacoustic waves in piezoelectric layered composites. Starting with the basic linear equations and relations of electromagnet elasticity of homogeneous anisotropic piezoelectric media, the book considers the conditions for possible field or partial conjugation of physical and mechanical fields at the junction of two homogeneous media with geometrically homogeneous surfaces. The variety of electromechanical boundary conditions and the separation of plane and anti-plane fields |

of elastic deformation in homogeneous piezoelectric crystals are discussed. Then, the statements of the electroacoustic problem in piezo textures are studied and a layered piecewise-homogeneous piezoelectric waveguide is introduced, with non-acoustic contact between different piezoelectric layers. Non-acoustic contact between different piezoelectric layers can lead to the propagation of a hybrid of electroactive waves of plane and anti-plane elastic deformations. In the last part of the book, the problem of controlling electroacoustic waves in a waveguide is formulated. A method for solving problems of control of electroacoustic waves by non-contact surface action is proposed. . |
