ImgFS: a transparent cryptography for stored images using a filesystem in userspace

Osama A. KHASHAN,Abdullah M. ZIN,Elankovan A. SUNDARARAJAN

Frontiers of Information Technology & Electronic Engineering 2015, Volume 16, Issue 1, Pages 28-42 doi: 10.1631/FITEE.1400133

Abstract: A filesystem in userspace (FUSE) can be used to bridge the gap.Nevertheless, current implementations of cryptographic FUSE-based file systems suffered from severalThe development of ImgFS has managed to solve weaknesses that have been identified on cryptographic FUSE-basedof security and transparency, its performance was competitive with other established cryptographic FUSE-based

Parametric computational study on butterfly-shaped hysteretic dampers

Ali Reza FARZAMPOUR, Matthew Roy EATHERTON

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 5, Pages 1214-1226 doi: 10.1007/s11709-019-0550-6

Abstract: A parametric computational study is conducted to investigate the shear yielding, flexural yielding, and lateral torsional buckling limit states for butterfly-shaped links. After validating the accuracy of the finite element (FE) modeling approach against previous experiments, 112 computational models with different geometrical properties were constructed and analyzed including consideration of initial imperfections. The resulting yielding moment, corresponding critical shear force, the accumulation of plastic strains through the length of links as well as the amount of energy dissipated are investigated. The results indicate that as the shape of the butterfly-shaped links become too straight or conversely too narrow in the middle, peak accumulated plastic strains increase. The significant effect of plate thickness on the buckling limit state is examined in this study. Results show that overstrength for these links (peak force divided by yield force) is between 1.2 and 4.5, with straight links producing larger overstrength. Additionally, proportioning the links to delay buckling, and designing the links to yield in the flexural mode are shown to improve energy dissipation.

Fused structures for safer and more economical constructions

Yu-Fei WU, Ying-Wu ZHOU, Biao HU, Xiaoxu HUANG, Scott SMITH

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 1, Pages 1-9 doi: 10.1007/s11709-019-0541-7

Abstract: By providing a fuse in a structure that is triggered at a certain level of over-loading, further increaseThe use of a fuse will also facilitate safer use of advanced construction materials such as fiber-reinforcedIn this case, a fuse can transfer the sudden and dangerous failure mode associated with brittle FRP debondingor rupture to a safe and ductile failure mode at the fuse location.
