Spinning reserve opportunity cost in hydroelectric plants
(2005-10-31)
Starting from the deregulated process of the Electric Sector, there was the need to attribute responsibilities to several agents and to elaborate appropriate forms of remuneration of the services rendered by the same. One ...

Towards coherent optical control of a single hole spin: Rabi rotation of a trion conditional on the spin state of the hole
(Pergamon-Elsevier B.V. Ltd, 2009-09-01)
A hole spin is a potential solid-state q-bit, that may be more robust against nuclear spin induced dephasing than an electron spin. Here we propose and demonstrate the sequential preparation, control and detection of a ...

Spin-glass-like behavior of uncompensated surface spins in NiO nanoparticulated powder
(ELSEVIER SCIENCE BVAMSTERDAM, 2013-08-02)
Nickel oxide nonoparticles successfully synthesized by a polymer percursor method are studied in this work. The analysis of X-ray powder diffraction data provides a mean crystallite size of 22 +/- 2 nm which is in a good ...
Quantum spin tunneling in a soluble quasi-spin model: an angle-based potential description
(Elsevier B.V., 2005-06-15)
We propose an approach which allows one to construct and use a potential function written in terms of an angle variable to describe interacting spin systems. We show how this can be implemented in the Lipkin-Meshkov-Glick, ...

Optimization of Spinning Reserve in Stand-alone Wind-Diesel Power Systems
(IntechOpen, 2010)
Spinning reserve carried on synchronized units is the most effective resource available to the system operators for managing unforeseen power unbalances, such as demand fluctuations and the sudden loss of generation ...
Local spin: A treatment beyond single determinant wave functions
(Elsevier Science, 2009-01)
This Letter describes a partitioning of the expectation value 〈 over(S, ^) 2 〉 of an N-electron system (molecule, ion, radical, etc.) into one- and two-center contributions. The proposal is valid for both independent and ...
