A photovoltaic forced ventilated façade (PV-FVF) as heat source for a heat pump: Assessing its energetical profit in nZEB buildings
(Elsevier, 2022-04)
The European Union is changing its energy model towards a more efficient and sustainable one. In this new outlook, the Heat Pump (HP) has become a leading technology in the building energy sector. The use of the air source ...
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 ...
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 ...
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 ...
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 ...
A Finite Element based Deep Learning solver for parametric PDEs
(Elsevier, 2022-03)
We introduce a dynamic Deep Learning (DL) architecture based on the Finite Element Method (FEM) to solve linear parametric Partial Differential Equations (PDEs). The connections between neurons in the architecture mimic ...
Sphingomyelin: What is it good for?
(Elsevier, 2022-12)
Sphingomyelin has been considered as a merely structural lipid for many years. However, this organelle-specific lipid has many other roles, including increasing membrane molecular order, acting as a source of ceramide in ...
On quadrature rules for solving Partial Differential Equations using Neural Networks
(Elsevier, 2022-04)
Neural Networks have been widely used to solve Partial Differential Equations. These methods require to approximate definite integrals using quadrature rules. Here, we illustrate via 1D numerical examples the quadrature ...
Damping in ram based vertical lathes and portal machines
(Elsevier, 2022)
Chatter vibrations originated by the machine structure are a major limitation for the productivity of ram based machines performing heavy duty operations. Consequently, the damping of the machine structure has a capital ...
