Janus Photonic Graphics by Stratified Assembly of Two Distinct Colloids

Advanced Functional Materials, EarlyView.
Double‐sided Janus photonic micropatterns with vivid structural colors are fabricated through a single‐step bottom‐up strategy. Density‐driven stratification and depletion‐mediated crystallization of PMMA and PS binary colloids lead to exclusive lattices on opposite surfaces under centrifugal force.

Pattern recognition in power-system security

International Journal of Electrical Power & Energy Systems, 1984
Abstract Power system security assessment is of great importance in power-system operation. To date, security evaluation has consisted of occasionally performing load flows and transient stability studies by computer simulation of current system status or by applying conventional direct methods. This type of security evaluation is very time-consuming
