The system of steel shear wall is an initiative resistance system against the lateral load such as an earthquake and the wind that has been researched in the last three decades. Currently, this system is noticed more than other systems because of adequate stiffness, ductility, and more energy absorption. The system of steel shear wall with corrugated sheets has been offered as an innovative sys...

Experiments were performed to observe the fracture behavior of thin-wall and initially-flawed aluminum tubes to internal gaseous detonation loading. The pressure load, with speeds exceeding 2 km/s, can be characterized as a pressure peak (ranging from 2 to 6 MPa in these experiments) followed by an expansion wave. Flaws were machined as external axial surface notches. Cracks ran both in the ups...

We demonstrate the construction of corrugated waveguides using stacked rings to propagate terahertz frequencies. The waveguide allows propagation of the same fundamental mode as an optical-fiber, namely, the HE(11) mode. This simple concept opens the way for corrugated wave-guides up to several terahertz, maintaining beam characteristics as for terahertz applications.

The strength of a corrugated container is usually determined and reported as crush strength under progressively increasing top-to-bottom compressive load. The test is performed in seconds in a controlled constant temperature and relative humidity environment. However, a dynamic strength test under controlled conditions cannot account for the reduction in load-carrying ability inherent in the ex...

Plant fibres are helically twisted cellulosic materials that bonded together by lignin and hemicellulose matrices.

Ubiquitous wireless distribution of multigigabit per second data rate for enabling new 5G and 6G paradigms can be only achieved by exploiting the wide frequency bands available in sub-THz spectrum (90-305 GHz). The high total attenuation at sub-THz, particular because rain humidity, poses a substantial challenge to achieve long links, not yet resolved lack amplifiers with adequate transmission ...

Despite their wide spread applications, the mechanical behavior of helically coiled structures has evaded an accurate understanding at any length scale (nano to macro) mainly due to their geometrical complexity. The advent of helically coiled micro/nanoscale structures in nano-robotics, nano-inductors, and impact protection coatings has necessitated the development of new methodologies for dete...

A stimuli-responsive hexameric oligophenol host undergoes amine-induced co-operative folding from a more fluorescent, more linear structure into less fluorescent, more curved or helically folded states, enabling easy identification and classification of the bound amine guests.
