2D evaluation of crack openings using smeared and embedded crack models
(Techno-press, 2010-12-01)
This work deals with the determination of crack openings in 2D reinforced concrete structures using the Finite Element Method with a smeared rotating crack model or an embedded crack model In the smeared crack model, the ...
A local-global scheme for tracking crack path in three-dimensional solids
(Techno-press, 2013-09-01)
This paper aims to contribute to the three-dimensional generalization of numerical prediction of crack propagation through the formulation of finite elements with embedded discontinuities. The analysis of crack propagation ...
Impacto psicosocial de la tecnología de información y comunicación (TIC): tecnoestrés, daños físicos y satisfacción laboral
(Universidad Católica de Colombia. Facultad de Psicología, 2008-12)
The introduction of information and communication technologies (ICT) in the organizations produced and still produces substantial changes in these structures at the modus operandi level and also with respect to the physical ...

A preliminary simulation for the development of an implantable pulsatile blood pump
(Techno-press, 2014-06)
A preliminary study of a new pulsatile pump, that will work to a frequency greater than 1 Hz, is presented. The fluid-structure interaction between a Newtonian blood flow and a piston drive that moves with periodic speed ...
Modeling of wind-induced fatigue of cold-formed steel sheet panels
(Techno-Press, 2014-01)
Wind-induced failure around screwed connections has been documented in roof and wall cladding systems made with steel sheet cold-formed panels during high wind events. Previous research has found that low cycle fatigue ...
Shear strength model for reinforced concrete corbels based on panel response
(Techno-Press, 2016)
Reinforced concrete corbels are generally used to transfer loads within a structural system, such as buildings, bridges, and facilities in general. They commonly present low aspect ratio, requiring an accurate model for ...
TECNOESTRÉS Y SATISFACCIÓN LABORAL DE LOS COLABORADORES DE UNA EMPRESA DE ALIMENTOS DURANTE LA PANDEMIA POR COVID-19
(Universidad de Guayaquil -Facultad de Ciencias Psicológicas, 2021)
El presente proyecto de investigación tuvo como objetivo establecer la relación entre el tecnoestrés y la satisfacción laboral de los colaboradores de una empresa de alimentos durante la pandemia por COVID-19. Esto se logró ...
