Generalized Sampling: From Fourier to Wavelet

, 2018
In this project we investigate generalized sampling as a tool for signal reconstruction and compression. Generalized sampling is a relatively new method for recovering any element in a finite dimensional space given finitely many samples in an arbitrary ...

The influence of boundary-conditions on resonant frquencies of cavities in 3-D FDTD algorithm using nonorthogonal coordinates. [PDF]

, 1994
The 3-dimensional finite-difference time-domain method in non-orthogonal co-ordinates (non-standard FDTD) is used to calculate the frequencies of resonators. The numerical boundary conditions of the method are presented.

Weaving Intelligence: Thermally Drawn Multimaterial Fibers Toward AI‐Enabled Smart Textiles

Advanced Materials, EarlyView.
Thermally drawn multimaterial fibers are rapidly advancing as intelligent structural units for next‐generation smart textiles. Integrating multimaterial architectures with neuromorphic and spiking‐neural‐network principles enables fabrics that can sense, compute, and adapt autonomously.

Programmable Stepwise Heteroepitaxial Growth of Colloidal Crystals With Different Phases

Advanced Materials, EarlyView.
Stepwise heteroepitaxial growth is adapted to colloidal crystal engineering with DNA, enabling face‐centered cubic (fcc) facets to grow on body‐centered cubic (bcc) crystals with 110 facets. This approach tolerates large lattice mismatches, extending heteroepitaxy beyond the limits of conventional atomic systems.

Analysis of the Stress State of a Layer with Two Cylindrical Swivel Joints and a Cylindrical Cavity

Journal of Mechanical Engineering
In practice, connections in the form of cylindrical swivel joints are often encountered. However, exact methods for calculating such models are absent. Therefore, the development of algorithms to solve such problems is relevant.
