Abstract: To accurately simulate the thin layer of linear dispersive media, an improved 3-D finite-difference time-domain (FDTD) method is proposed. The inclusion of a weak conditionally stabilized ...

Can light behave like a whirlwind? It turns out it can—and such "optical tornadoes" have now been created in an extremely small structure by scientists from the Faculty of Physics at the University of ...

From skyscrapers to massive bridges, I-beams help engineers build stronger structures with less material. Their distinctive shape is designed to handle bending loads as efficiently as possible.

Abstract: Given a relation and a ranking of its tuples, but no information about the ranking function, we are interested in synthesizing simple scoring functions that reproduce the ranking. Our system ...

WASHINGTON (AP) — President Donald Trump said Monday that he won't tear down the Kennedy Center but said it needs to be closed for about two years for work that cannot be done with patrons coming and ...

“Multiscale Structural Mechanics: Top-Down Modeling of Composite Structures Using Mechanics of Structure Genome” delivers a unified approach to composites modeling based on the concept of structure ...

Drawing a kestrel bird becomes approachable when the process is broken into clear, structured steps that focus on form and observation. This tutorial guides you through creating a kestrel from the ...
