Practical framework for frequency stability studies in power systems with renewable energy sources (IEEE-Inst Electrical Electronics Engineers, 2020)The transition from power systems dominated by synchronous machines to systems based on converter-based generation technologies (CGTs), is weakening currently robust power systems by reducing system inertia with the ...

(Elsevier, 2020)We introduce the notion of pre expansivity for cellular automata (CA): it is the property of being positively expansive on asymptotic pairs of configurations (i.e. configurations that differ in only finitely many positions). ...
-
(Elsevier, 2016)Supposed pre-Mesozoic igneous and metamorphic rocks from northern Chile are reviewed in the light of twenty-one new SHRIMP U-Pb zircon age determinations. Metamorphic rocks from the precordillera upthrust belt mostly show ...
-
(Elsevier, 2015)We examine whether the expectations of pre-service elementary school teachers about students' achievement, and their beliefs regarding student need for academic support, are influenced by future teachers' mathematics anxiety ...
-
(Elsevier, 2015)We consider the problem of separating maximally violated inequalities for the precedence constrained knapsack problem. Though we consider maximally violated constraints in a very general way, special emphasis is placed on ...
-
(Royal Astronomical Society, 2015)We present the results of smoothed particle hydrodynamics (SPH) simulations of the disc around the young, eccentric stellar binary HD 104237. We find that the binary clears out a large cavity in the disc, driving a ...
-
(2006-09)Extratropical precipitation is primarily produced by cold and warm fronts associated with surface cyclones and upper-level troughs. The growth of these midlatitude storms is partially controlled by the dry baroclinicity ...
-
(Elsevier, 2017)The precipitation kinetics of secondary phases in a 10.5%Cr heat resistant steel, designed by the authors, was studied experimentally and theoretically. Experimental data of nucleation, growth and coarsening stages for ...
-
(Royal Astronomical Society, 2014-02-20)We present radial velocity measurements of a sample of M5V–M9V stars from our Red-Optical Planet Survey, operating at 0.652–1.025 µm. Radial velocities for 15 stars, with rms precision down to 2.5 m s−1 over a week-long ...
-
(Springer International Publishing, 2019)© 2018, Italian Society of Endocrinology (SIE).Purpose: Puberty onset exhibits remarkable inter-individual and ethnic differences. 5% of Chileans are indigenous but puberty ethnic disparities have not been studied. We aim ...
-
(IOP, 2020)We deform, in pure shear, a thin sample of Cu50Zr50 metallic glass using a molecular dynamics simulation up to, and including, failure. The experiment is repeated ten times in order to have average values and standard ...
-
(Assoc Computing Machinery, USA, 2020)The predecessor problem is a key component of the fundamental sorting-and-searching core of algorithmic problems. While binary search is the optimal solution in the comparison model, more realistic machine models on integer ...
-
(Nature, 2020)Applications from finance to epidemiology and cyber-security require accurate forecasts of dynamic phenomena, which are often only partially observed. We demonstrate that a system's predictability degrades as a function ...
-
(Elsevier Inc., 2018)Hotspots are generated by partial melting due to hot plumes rising within the Earth's mantle, and when tectonic plates move relative to the plume source, hotspot tracks form. Off South America, the oceanic Nazca Plate hosts ...
-
(Pergamon-Elsevier, 2016)Accurate characterization of two phase bubbly flows is crucial in many industrial processes such as fluidized reactors, ore froth flotation, etc. The bubble size determines the rate at which components present in the gas ...
-
(Springer, 2022)Non-dimensional similarity groups and analytically solvable proximity equations can be used to estimate integral fluid film parameters of elastohydrodynamically lubricated (EHL) contacts. In this contribution, we demonstrate ...
-
(Emerald Group Publishing, 2013)Purpose – Twitter is a popular microblogging service which has proven, in recent years, its potential for propagating news and information about developing events. The purpose of this paper is to focus on the analysis ...
-
(SAGE, 2020)The obesity epidemic progresses everywhere across the globe, and implementing frequent nationwide surveys to measure the percentage of obese population is costly. Conversely, country-level food sales information can be ...
