Minimum d-convex partition of a multidimensional polyhedron with holes [PDF]
Computer Science Journal of Moldova, 2008 In a normed space Rn over the field of real numbers R, which is an α-space [36, 39], one derives the formula expressing the minimum number of d-convex pieces into which a geometric n-dimensional polyhedron with holes can be partitioned.

Complex time series modeling and analysis for rotor dynamics identification
, 1997 A new time series method, directional ARMAX (dARMAX) model-based approach, is proposed for rotor dynamics identification. The dARMAX processes complex-varied signals, utilizing the complex modal resting theory which enables the separation of the backward

Multi‐Biomimetic Structural Colors Inspired by Pearls and Bird Feathers
Advanced Materials, EarlyView.A dual‐biomimetic strategy mimicking pearls and bird feathers is proposed to construct full‐gamut structural colors. By integrating a non‐strictly periodic inorganic multilayer architecture with tunable light absorbers, this facile approach circumvents the complex fabrication of traditional 1D photonic crystals, offering immense potential for cosmetics,

Optimal Control of Brushless Doubly Fed Wind Power Generator under Zero-Voltage Ride-Through
EnergiesIn the grid-connected operation dynamics of brushless doubly fed generators (BDFGs), a dip in the grid voltage is equivalent to suddenly adding a reverse voltage source at the parallel node.

CW-CNN & CW-AN: Convolutional Networks and Attention Networks for CW-Complexes
CoRRWe present a novel framework for learning on CW-complex structured data points. Recent advances have discussed CW-complexes as ideal learning representations for problems in cheminformatics. However, there is a lack of available machine learning methods suitable for learning on CW-complexes. In this paper we develop notions of convolution and attention

Additively Manufactured Porous Ceramics as Tunable Dielectrics for Passive Temperature Sensing
Advanced Materials Technologies, EarlyView.Porous ceramic lattices, 3D‐printed from a multicomponent oxide ink, are integrated with LC resonators for passive wireless temperature sensing. By tuning porosity, the dielectric properties and RF response are engineered to produce distinct resonant frequency shifts with temperature. The results establish a structure‐driven approach to customizing the

Advanced Materials Technologies, EarlyView.Programmable luminescent tags based on organic room‐temperature phosphorescence are shown to be governed by oxygen incorporation during fabrication. Oxygen‐free processing enables immediate phosphorescence activation, controlled thermal preconditioning, and tunable activation doses.

Reconfigurable Millimeter-Wave Generation via Mutually Injected Spin-VCSELs
PhotonicsWe propose a novel scheme for generating high-frequency millimeter-wave signals by exploiting period-one (P1) dynamics in a mutual injection configuration of two spin-polarized vertical-cavity surface-emitting lasers (spin-VCSELs).
