... the size of the strain gradient was obtained, as explained earlier, it could be utilized for size optimization of the composite and hence, a set of polycrystalline superlattice structures of different periodicities “Δ” (Δ = 20, 40, 60, 80, and 100 nm) was fabricated and utilized for studying the ME...

... such as wind and biomass energy resources ( Xu et al., 2022 ). For example, solar photovoltaic and wind energy can be complementary even in the same location and period. Utilization of solar photovoltaic hybrid energy systems is an effective way to smooth the output power from the perspective...

... left gender issues largely untouched. This was characteristic of physics education research as a whole in this period: the instruments that enabled the rise of this subfield within the physics discipline were primarily tests through which physicists could probe the conceptual understanding...

... to be nonempty and compact. It is assumed that the function f: X × U → X is a sufficiently smooth vector field in X and that the full state is sampled periodically with a sampling period Δ; that is, measurements of the state vector are available at the time instants...

... supply not being able to satisfy the load demand. For a given period (t), it can be calculated by Eq. ( 2.1 ) ( Yang et al., 2009 ), (2.1) LPSP = ∑ t = 1 N Power failure time ( P supply ( t ) < P demand ( t ) ) N This objective can...

... no overlap between them. Oscillations Although oscillations are usually a prerequisite for understanding waves, there appears to have been very little research done specifically on oscillations. The main concepts investigated are listed below. Relation between period and amplitude Among the first studies...
