Influence of MWCNT/surfactant dispersions on the mechanical properties of Portland cement pastes
This work studies the reinforcing effect of Multi Walled Carbon Nanotubes (MWCNT) on cement pastes. A 0.35% solid concentration of MWCNT in powder was dispersed in deionized water with sodium dodecyl sulfate (cationic ...
Robust channel estimation for ultra-wide band communicationsEstimativa robusta de canais de comunicação de ultrabanda largaEstimación robusta de canales de comunicaciones de ultra banda ancha
UWB (ultra-wide band) systems transmit low power signals through communication channels that operate in closed environments and in short distances resulting in multiple propagation trajectories. Moreover, the noise affecting ...
Análisis de algoritmos para la construcción de arreglo de sufijos en tiempo lineal
El avance en la investigación de los arreglos de sufijos permitió en el año 2003 el planteamiento de tres algoritmos de tiempo lineal para la generación de tales estructuras. Anterior a estos se venía trabajando con ...
Systemic archetypes for value co-creation based on collaborative cores: Case study at a telecommunication company [Arquetipos Sistémicos para la co-creación de valor con base en núcleos colaborativos: Un estudio de caso en una empresa de telecomunicaciones]
Currently value creation is not an exclusive aspect of the company; the clients co-creator role has taken preponderance due to the contribution of co-creation models, which demonstrate its utility empirically but does not ...
Influence of chemical composition on the biochemical methane potential of agro-industrial substrates from Estonia
Batch trials were carried out to evaluate the Biochemical Methane Potential (BMP) of 61 different substrates collected from agricultural farms and industrial sites in Estonia. Tests were performed in 500 mL plasma bottles ...
