On strain hardening mechanism in gradient nanostructures [PDF]
, 2017 Experiments have shown that a gradient design, in which grain size spans over four orders of magnitude, can make strong nanomaterials ductile. The enhanced ductility is attributed to the considerable strain hardening capability obtained in the gradient ...

An aspect-oriented framework for systematic security hardening of software [PDF]
, 2018 In this thesis, we address the problems related to the security hardening of open source software. Accordingly, we first propose an aspect-oriented and pattern-based approach for systematic security hardening.
