Modeling power grids
P. A. Rikvold, I. Abou Hamad, B. Israels +1
We present a method to construct random model power grids that closely match statistical properties of a real power grid. The model grids are more difficult to partition than a rea…
Parameter Estimation by Density Functional Theory for a Lattice-gas Model of Br and Cl Chemisorption on Ag(100)
Tjipto Juwono, Ibrahim Abou Hamad, Per Arne Rikvold +1
We study Bromine and Chlorine chemisorption on a Ag(100) surface, using a lattice-gas model and the quantum-mechanical Density Functional Theory (DFT) method. In this model the Br…
Floridian high-voltage power-grid network partitioning and cluster optimization using simulated annealing
Ibrahim Abou Hamad, Per Arne Rikvold, Svetlana V. Poroseva
Many partitioning methods may be used to partition a network into smaller clusters while minimizing the number of cuts needed. However, other considerations must also be taken into…
A New Charging Method for Li-ion Batteries: Dependence of the charging time on the Direction of an Additional Oscillating Field
I. Abou Hamad, M. A. Novotny, D. O. Wipf +1
We have recently proposed a new method for charging Li-ion batteries based on large-scale molecular dynamics studies (I. Abou Hamad et al, Phys. Chem. Chem. Phys., 12, 2740 (2010))…
Spectral matrix methods for partitioning power grids: Applications to the Italian and Floridian high-voltage networks
Ibrahim Abou Hamad, Brett Israels, Per Arne Rikvold +1
Intentional islanding is used to limit cascading power failures by isolating highly connected "islands" with local generating capacity. To efficiently isolate an island, one should…
A new battery-charging method suggested by molecular dynamics simulations
Ibrahim Abou Hamad, M. A. Novotny, D. Wipf +1
Based on large-scale molecular dynamics simulations, we propose a new charging method that should be capable of charging a Lithium-ion battery in a fraction of the time needed when…
