Notes on Conformal Invisibility Devices [PDF]

, 2006
As a consequence of the wave nature of light, invisibility devices based on isotropic media cannot be perfect. The principal distortions of invisibility are due to reflections and time delays.

Behavior-Based Outlier Detection for Network Access Control Systems [PDF]

, 2019
Network Access Control (NAC) systems manage the access of new devices into enterprise networks to prevent unauthorised devices from attacking network services. The main difficulty with this approach is that NAC cannot detect abnormal behaviour of devices

Flexible Graphite-on-Paper Piezoresistive Sensors

Sensors, 2012
We demonstrate novel graphite-on-paper piezoresistive devices. The graphite was used as sensing component. The fabrication process can be finished in a short time with simple tools (e.g., a scissor and a pencil).
