A Sinusoidally Architected Helicoidal Biocomposite

Biocomposite Materials

Composite materials may be restricted to emphasize those materials that contain a continuous matrix constituent that binds together and provides form to an array of a stronger, stiffer reinforcement constituent. The resulting composite material has a balance of structural properties that is superior to either constituent material alone. Combining the advantages of inorganic and organic componen...

Fabrication of 3d Micro-architected/ Nano-architected Materials

'Architected' Cloud Solutions Revealed

“It's getting harder to focus on the vision of cloud computing these days. While there are still plenty of critical and complex problems to solve, and many, many implications of this disruptive operations model that have yet to be understood, the truth is that we've entered a new phase in the evolution of cloud adoption. Real work now exceeds theory when it comes to both new online content and ...

Resilient 3D hierarchical architected metamaterials.

Hierarchically designed structures with architectural features that span across multiple length scales are found in numerous hard biomaterials, like bone, wood, and glass sponge skeletons, as well as manmade structures, like the Eiffel Tower. It has been hypothesized that their mechanical robustness and damage tolerance stem from sophisticated ordering within the constituents, but the specific ...

Reactance of a Sinusoidally Driven Antenna

This problem is based on the overoptimistic claim in [1] that the reactance of an antenna can be decomposed into capacitive and inductive reactances. Deduction of antenna reactance via so-called complex Poynting theorem (sec. 13.14 of [2], sec. 2.20 of [3]) goes back at least to sec. 5 of [4]. See also chap. 8 of [5]. We consider only media with unit relative permittivity and permeability. For ...
