    • Hardy inequalities, observability, and control for the wave and schrödinger equations with singular potentials 

      Vancostenoble J.; Zuazua E. (SIAM Journal on Mathematical Analysis, 2009-12-31)
      We address the question of exact controllability of the wave and Schrodinger equa\-tions perturbed by a singular inverse-square potential. Exact boundary controllability is proved in the range of subcritical coefficients ...
    • Reducing variability in the cost of energy of ocean energy arrays 

      Topper M.B.R; Nava V.; Collin A. J.; Bould D.; Ferri F.; Olson S. S.; Dallmann A. R.; Roberts J. D.; Ruiz-Minguela P.; Jeffrey H. F. (Renewable and Sustainable Energy Reviews, 2019-09)
      Variability in the predicted cost of energy of an ocean energy converter array is more substantial than for other forms of energy generation, due to the combined stochastic action of weather conditions and failures. If the ...
