Abstract: This paper investigates a novel recurrent neural network (NN)-based vector control approach for single-phase grid-connected converters (GCCs) with L (inductor), LC (inductor-capacitor) and LCL (inductor-capacitor-inductor) filters and provides their comparison study with the conventional standard vector control method. A single neural network controller replaces two current-loop PI co...

Onsager’s phenomenological equations successfully describe irreversible thermodynamic processes. They assume a symmetric coupling matrix between thermodynamic fluxes and forces. It is easily shown that the antisymmetric part of a coupling matrix does not contribute to dissipation. Therefore, entropy production is exclusively governed by the symmetric matrix even in the presence of antisymmetric...

Languages instantiate many different kinds of dependencies, holding between adjacent or nonadjacent elements. In the domain of phonotactics, while sensitivity to adjacent dependencies emerges between 6 and 10 months, it is unknown when sensitivity to nonadjacent dependencies emerges. The present study tests a perceptual equivalent of the Labial-Coronal (LC) bias, a dependency involving two non-...

A systematic, computational and scaling analysis of defect textures in polygonal arrangement of cylindrical particles embedded in a cholesteric (Ch) liquid crystal matrix is performed using the Landau–de Gennes model for chiral self-assembly, with strong anchoring at the particles’ surface. The defect textures and LC phases observed are investigated as a function of chirality, elastic anisotrop...

The clinical application of Traditional Chinese medicine (TCM), using several herbs in combination (called formulas), has a history of more than one thousand years. However, the bioactive compounds that account for their therapeutic effects remain unclear. We hypothesized that the material basis of a formula are those compounds with a high content in the decoction that are maintained at a certa...

This work investigates the dynamics of modulated waves in a coupled nonlinear LC transmission line. By means of a method based on the semi-discrete limit and in suitably scaled coordinates, we derive the two-dimensional NLS equation governing the propagation of slowly modulated waves in the network. The exact transverse solution is found and the analytical criteria of stability of this solution...

In this paper, the main defects of LC-based Σ∆ modulators due to process variations are presented. Resonance frequency shift of LC tank circuit, which was discussed is some publications, is shown to be one among many other possible defects that are discussed in this paper. The effect of each defect on modulator output spectrum is shown and discussed. It is suggested that the information extract...

This paper deals with generalized approach to the reciprocating piston compressor driven by oscillating electrical motor and possibilities of development of new structures of the device. The current term linear compressor, ipso facto, restricts the considered devices only with a linear motion of the piston. Therefore the more general term oscillating motor-compressors is used in the paper, in w...

background: to study the chemical constituents and larvicidal activity of essential oil extracted from the leaves of coccinia grandis against three mosquito species. methods: essential oil was extracted by hydro distillation using clevenger apparatus and was analyzed for chemical constituents by gas chromatography-mass spectrophotometry (gc-ms). larvicidal activity was recorded after 12 and 24h...
