Role of zeolite properties in bio-oil deoxygenation and hydrocarbons production by catalytic cracking
(Elsevier, 2022-03)
A comparison between the behavior of Y and ZSM-5 zeolites having the same Si/Al ratio was established in the catalytic cracking of bio-oil for producing fuels and platform chemicals. The catalysts were prepared by agglomerating ...
Fast and efficient address search in System-on-a-Programmable-Chip using binary trees
(Elsevier, 2021-12)
One processing task in Ethernet nodes is to manage Media Access Control (MAC) addresses: search, insert new, and delete old ones. For this purpose, Content-Addressable Memorys (CAMs) offer low latency and no collisions; ...
Analysis of displacement path dependence in mixed mode cohesive law
(Elsevier, 2022-12)
In the present work, a general theoretical analysis is presented and novel mathematical expressions are derived to obtain the cohesive law of adhesive joints under mixed-mode loading.
It is theoretically stated that the ...
Survival in the Intensive Care Unit: A prognosis model based on Bayesian classifiers
(Elsevier, 2021-05)
We develop a predictive prognosis model to support medical experts in their clinical decision-making process in Intensive Care Units (ICUs) (a) to enhance early mortality prediction, (b) to make more efficient medical ...
In line upgrading of biomass fast pyrolysis products using low-cost catalysts
(Elsevier, 2021-07)
Biomass pyrolysis and the in-line catalytic cracking of the pyrolysis volatile stream has been approached in this study. The pyrolysis step was carried out in a conical spouted bed reactor at 500 °C, whereas the inert sand ...
On the relationship between cutting forces and anisotropy features in the milling of LPBF Inconel 718 for near net shape parts
(Elsevier, 2021-11)
The versatility and potential applications of additive manufacturing have accelerated the development of additive/subtractive hybrid manufacturing methods. LPBF processes are exceptionally efficient at producing complex-shaped, ...
Experimental analysis and numerical simulation of wave overtopping on a fixed vertical cylinder under regular waves
(Elsevier, 2022-04)
Wave overtopping phenomenon affects relatively narrow offshore marine structures different from shoreline linear structures, where there is not defined a precise prediction methodology as it is the case of the behaviour ...
Antioxidant activity and phenolic profiles of ciders from the Basque Country
(Elsevier, 2021-06)
The contribution of the individual polyphenols of Basque cider to the antioxidant activity and browning has been determined. Nineteen monovarietal musts were obtained using different varieties of cider apples throughout ...
Embedded firewall for on-chip bus transactions
(Elsevier, 2022-03)
This article presents a novel approach towards System-on-Chip (SoC) security. Although communications security and operating system hardening have been studied, new application opportunities and menaces have appeared with ...
Improvement of boring operations by means of mode coupling effect
(Elsevier, 2022-05)
Boring bars are inherently slender tools which are prone to show chatter problems due to their low dynamic stiffness and damping, being this problem their main limitation in productivity. The onset of chatter is mainly ...
