This paper aims to illuminate the influence of hydrodynamic pressure generated in a water storage tank on behavior saturated sand that its support. Experimental tests were performed two cylindrical models using fabricated shaking table which consists flexible laminar shear box. The first model is partially full water, and second one with an equivalent load simulate without pressure. Three earth...

Within the past decade, seismic isolation systems have gained rapid popularity in the earthquake resistant design of bridge structures. This popularity has come in response to the inadequacy of earlier seismic design and retrofit methodologies. The mechanical shortcomings and subsequent failure mechanisms associated with the early elastic seismic design philosophy are first presented, followed ...

Magnetorheological (MR) dampers have the advantage of being tuned by low voltages. This has attracted many researchers to develop semi-active control of structures in theory and practice. Most of the control strategies first obtain the desired forces of dampers without taking their dynamics into consideration and then determine the input voltages according to those forces. As a result, these st...

In August-September 2005, El Centro, Inc., a community immigrant rights organization, conducted a survey of the Latino immigrant community in the Kansas City area. This survey was designed in partnership with Latino immigrant leaders working with El Centro to advance the general public’s understanding of immigrant concerns and enhance leaders’ ability to respond to community needs. The sample i...

Resumen.—La importancia de la formación del puente terrestre de Panamá para la diversificación de los mamíferos en el Nuevo Mundo ha sido bien documentada. Sin embargo, sólo recientemente se han presentado estudios que investigan el rol de este puente de tierra en la diversificación de las aves. Empleamos datos de ADN mitocondrial para reconstruir la filogenia del grupo de las tángaras (Thraupi...

ste trabajo presenta una solución para resolver un sistema de ecuaciones lineales por medio del método de Householder, teniendo como base un algoritmo que utiliza en paralelo «n» procesadores, y como medio de comunicación entre los procesadores una interfaz MPI. El Programa que se desarrollo fue escrito para el compilador mpcc (Compilador de C para paso de mensajes de la interfaz MPI), para la ...
