typically, two configurations are used for energy harvesting, with different advantages: piezoelastic and piezomagnetoelastic. best performance of piezoelastic configuration is limited to its narrow bandwidth around the resonance frequency. if the excitation frequency slightly deviates from the resonance frequency, the power-out is severely reduced. to overcome this, the piezomagnetoelastic has...

The limited knowledge of the behaviour modular buildings subjected to different loading scenarios and thereby lack design guidelines hinder growth construction practices despite its widespread benefits. In order understand robustness building systems, a case study was carried out using numerical analysis method evaluate ten-storey braced frame with systems. Two types modules span lengths were u...

Flexible risers are usually used as conveying systems to bring ocean resources from sea bed up onshore. Under environments, need bear complex loads and it is crucial comprehensively examine riser's configurations analyze structural dynamic performances under excitation of bottom vehicle motions, guarantee safe operation required service lives. In this study, considering a saddle-shaped riser, t...

Some novel structural features of the polar lobe of the egg of Crepidula are described. The significance of two kinds of aggregate is discussed in relation to the morphogenetic factors present in polar lobes generally. Surface configurations of the polar lobe are also described.

This is an essay on the historical landmarks leading to the study of principal configurations on surfaces, their structural stability and further generalizations. Here it is pointed out that in the work of Monge, 1796, are found elements of the qualitative theory of differential equations, founded by Poincaré in 1881. Two open problems are proposed.

Density functional theory (DFT) based calculations have been performed to examine the relaxations of tautomers of 4–hydroxy–6–methylpyridin–2(1H)–one (MPO), as a representative of pyridinone derivatives, at the fullerene (C60) surfaces. Optimized molecular properties including energies, dipole moments and atomic scale quadrupole coupling constants (CQ) have been e...

Feature models are widely used for modelling variability present in a Software Product Line family. We propose using cardinality-based feature models and clonable features to model and manage the evolution of the structural variability present in pervasive systems, composed by a large variety of heterogeneous devices. The use of clonable features increases the expressiveness of feature models, ...

We investigated structural disorder by a new structural parameter, quasi-nearest atom (QNA), in atomistic configurations of eight metallic glass-forming systems generated through molecular dynamics simulations at various temperatures. Structural analysis reveals that the scaled distribution of the number of QNA appears to be an universal property of metallic liquids and the spatial distribution...
