The Role of the Demand for Environmental Quality in Driving Transitions to Low-Polluting Energy Sources
(Basque Centre for Climate Change/Klima Aldaketa Ikergai, 2012-08-14)
This policy briefing reports on research into historical examples where the public demanded environmental improvements, government may have responded to this demand and legislation introduced may helped lead to transitions ...
Low Climate Stabilisation under Diverse Growth and Convergence Scenarios
(Basque Centre for Climate Change/Klima Aldaketa Ikergai, 2012-08-01)
In the last decade, a few papers have analysed the consequences of achieving the greenhouse gas concentration levels necessary to maintain global temperature increases below 2 degrees Celsius above preindustrial levels. ...
First-principles study of the electronic and magnetic properties of defective carbon nanostructures
(2012-04-12)
Using ab initio calculations we habe carried out an extensive study of the electronic and magnetic propeerties of defects and impurities in graphene and carbon nanotubes. In particular, we have focused on the following ...
Cost effectiveness of a combination of instruments for global warming: a quantitative approach for Spain
(Springer, 2012-03)
Climate change is an important environmental problem and one whose economic implications are many and varied. This paper starts with the presumption that mitigation of greenhouse gases is a necessary policy that has to be ...
Subdiffusion of nonlinear waves in quasiperiodic potentials
(IOP Publishing, 2012-10-23)
We study the time evolution of wave packets in one-dimensional quasiperiodic lattices which localize linear waves. Nonlinearity (related to two-body interactions) has a destructive effect on localization, as observed ...
Robust speed control for a variable speed wind turbine
(ICIC International, 2012-11)
Modern wind turbines are designed in order to work in variable speed opera-tions. To perform this task, these turbines are provided with adjustable speed generators, like the double feed induction generator (DFIG). One of ...
An observer-based vaccination control law for an SEIR epidemic model based on feedback linearization techniques for nonlinear systems
(Springer, 2012-09)
This paper presents a vaccination strategy for fighting against the propagation of epidemic diseases. The disease propagation is described by an SEIR (susceptible plus infected plus infectious plus removed populations) ...
Sliding Mode Control Strategy for Wind Turbine Power Maximization
(MDPI, 2012-07)
The efficiency of the wind power conversions systems can be greatly improved using an appropriate control algorithm. In this work, a sliding mode control for variable speed wind turbine that incorporates a doubly fed ...
Black Holes, Cosmological Solutions, Future Singularities, and Their Thermodynamical Properties in Modified Gravity Theorie
(MDPI, 2012-09-18)
Along this review, we focus on the study of several properties of modified
gravity theories, in particular on black-hole solutions and its comparison with those solutions in General Relativity, and on Friedmann–Lemaˆıtr ...
Oracles for audio chord estimation
(2012)
This paper explores how audio chord estimation could improve if information about chord boundaries or beat onsets is revealed by an oracle. Chord estimation at the frame level is compared with three simulations, each using ...
