Bridged composite right/left handed unit cell with all-pass and triple band response
(2012)A modified design of the composite right/left handed (CRLH) unit cell showing all-pass and triple band response is proposed. By using an additional inductance which cross-couples the input and output ports of the conventional ... -
C 3 matching for asymptotically flat spacetimes
(Institute of Physics Publishing, 2019)We propose a criterion for finding the minimum distance at which an interior solution of Einstein's equations can be matched with an exterior asymptotically flat solution. The location of the matching hypersurface is thus ... -

Celebrity profiling on twitter using sociolinguistic features notebook for PAN at CLEF 2019
(CEUR-WS, 2019)Social networks have been a revolutionary scenario for celebrities because they allow them to reach a wider audience with much higher frequency than using traditional means. These platforms enable them to improve or sometimes ... -
CFD and 1D simulation of transient flow effect on air vessel
(BHR Group Limited, 2018)The estimation of unsteady parameters in two-phase condition is crucial for the safety and reliability of the hydraulic systems. There are plenty of one-dimensional (1D) simulation tools for unsteady flow estimation being ... -
Change and variability: A framework in studies on the first year of life
(Universidad Catolica de Colombia, 2013)This article presents empirical evidence of variability and change in the performance of young children in causality tasks, highlighting the relevance of nonlinear perspective in studies about the first year of life. Using ... -
Characterization and Modeling of the viscoelastic behavior of hydrocolloid-based films using classical and fractional rheological models
(Cartagena de Indias, 2021-11-18)Hydrocolloid-based films are a good alternative in the development of biodegradable films due to their properties, such as non-toxicity, functionality, and biodegradability, among others. In this work, films based on ... -
