Small-energy series for one-dimensional quantum-mechanical models with non-symmetric potentials
(Springer, 2015-06)
We generalize a small-energy expansion for one-dimensional quantum-mechanical models proposed recently by other authors. The original approach was devised to treat symmetric potentials and here we show how to extend it to ...
Optimization of the TEGs Configuration (Series/Parallel) in Energy Harvesting Systems with Low-Voltage Thermoelectric Generators Connected to Ultra-Low Voltage DC-DC Converters
(Mdpi, 2020-05-01)
Solar radiation and human activity generate ubiquitous temperature gradients that could be harvested by thermoelectric generators (TEGs). However, most of these temperature gradients are in the range of very few degrees ...
Effects of FACTS devices on power system performance in view of small-signal or great disturbances
(2003-01-01)
The problem of power system stability including the effects of Flexible Alternating Current Transmission System (FACTS) is approached. The Controlled Series Compensator and the Static Var Compensator (SVC) are considered, ...
Ten systemic steps for sustainable energy savings in small and medium enterprises
(Journal of Physics: Conference Series, 2019)
A numerical study of the Lieb-Thirring kinetic energy lower bound
(Taylor and Francis, 2016)
In this work, the Lieb-Thirring kinetic energy bound is numerically examined for a variety of systems: the hydrogen-like atoms, neutral atoms, isoelectronic series of atomic ions, the Hooke's atom and some small molecules. ...

Multifractal behavior of commodity markets: Fuel versus non-fuel products
(Elsevier Science, 2016-09-01)
We investigate multifractal properties of commodity time series using multifractal detrended fluctuation analysis (MF-DFA). We find that agricultural and energy-related commodities exhibit very similar behavior, while the ...
