Hardware-in-the-loop testing framework for active accumulator wave energy conve...

The hardware-in-the-loop technique is a hybrid co-simulation approach that joins real physical and virtual components. The real components may be the power take-off while the virtual ones the numerical models of sea wave and wave energy converter hydrodynamics. This simulation approach has been published with some regularity, however a review of the state-of-the-art has not been found, in particular in the rese...

Local and global indeterminacy and transition dynamics in a growth model with p...

This paper studies local and global indeterminacy and transition dynamics in an endogenous growth model where public goods increase production and the household’s utility. We study the impact on economic growth in the face of valuing public goods and socially conscious economic agents. When public goods are undervalued, the economy steadily converges to a unique low-growth equilibrium. As the utility share of p...

Is native forest an alternative to prevent wildfire in the WUI in Central Portu...

The expansion of the 2017 mega-fires in Portugal was observed to be locally halted by native forest patches. Here we present spatial simulation scenarios of fire behaviour to assess whether native forest cover mitigates fire spread during extreme wildfire conditions in wildland-urban interface (WUI) areas around Industrial Zones (IZs). Our results suggest that broadleaved forest cover can reduce fireline intens...

Experimental study of wave energy converter arrays adapted to a semi-submersibl...

The design of an offshore wind turbine floating platform seeks to minimize platform pitching motions that otherwise generate large accelerations and loads on the turbine, nacelle and blades, and decrease their lifetime. This objective is harder to achieve as the upscaling to more powerful wind turbines amplify the effects of pitching motions since the wind turbines’ height and mass are higher. Thus, innovative ...

Experimental analysis of wave energy converters concentrically attached on a fl...

This paper presents an initial experimental study of wave energy converters concentrically arranged and attached on a floating offshore platform model. The 1:27 scale model, has been designed, built and tested, in two main situations, without and with twelve cone shape wave energy converters. To simulate the power take-off system in each wave energy converter, rotational friction dampers have been installed on ...

Global bifurcation mechanism and local stability of identical and equidistant r...

We provide an analytical description of possible spatial patterns in economic geography models with three identical and equidistant regions by applying results from General Bifurcation mechanisms. We then use Pflüger’s (2004, Reg Sci Urb Econ) model to show what spatial patterns can be uncovered analytically. As the freeness of trade increases, a uniform distribution undergoes a direct bifurcation that leads to...

Economic geography meets Hotelling: a home-sweet-home effect

Process mineralogy of bacterial oxidized gold ore in São Bento Mine (Brasil).

The São Bento deposit (Santa Bárbara, MG) occurs in the middle portion of the Quadrilátero Ferrífero (latu sensu), hosted by the São Bento iron formation. The most important minerals in the deposit are arsenopyrite, pyrrhotite, chalcopyrite, sphalerite, galena, electrum, magnetite, ilmenite, siderite, ankerite, calcite, quartz, chlorite, stilpnomelane and muscovite. A mineralogical characterization of samples f...
