Journal of Economic and Financial Sciences, 2009 Unemployment in South Africa has reached crisis proportions and does not seem to be decreasing in concurrence with the more propitious economic reality. Indeed, the unemployment process seems to be isolated from economic reality and has developed a life ...

Hardware Security Implications of Reliability, Remanence, and Recovery in Embedded Memory
Journal of Hardware and Systems Security, 2018 Secure semiconductor devices usually destroy key material on tamper detection. However, data remanence effect in SRAM and Flash/EEPROM makes secure erasure process more challenging. On the other hand, data integrity of the embedded memory is essential to

Trapdoor Viscous Remanent Magnetization
Geophysical Research Letters, 2023 AbstractViscous remanent magnetization (VRM) in multidomain (MD) particles has many puzzling properties that deviate from the current VRM theory, based on Néel's single‐domain model of magnetic particles with an almost symmetric double‐well potential.
