Abstract Influence operations are large-scale efforts to manipulate public opinion. The rapid detection and disruption of these operations is critical for healthy public discourse. Emergent AI technologies may enable novel operations that evade detec

The study examines system's disturbances arising from the rapid increase in load demand due to urbanization on the 132kV Afam Port-Harcourt power transmission network. The prevalent disturbances encountered by this network are voltage sags, voltage s

X-ray optics based on MEMS technologies can provide future astronomical missions with ultra light-weight and high-performance optical systems. Curvilinear micropores vertical to a thin wafer are made by using DRIE (Deep Reactive Ion Etching) or X-ray

A measurement technique, pulsed thermoluminescence, is described which uses short thermal pulses to excite trapped carriers leading to radiative recombination. The pulses are obtained using microstructures with approximately 500 micros thermal time c

High-aspect-ratio channels may be coated using atomic layer deposition (ALD) due to the unique self-limiting nature of the process, and this has been often demonstrated using deep reactive-ion etched trenches in silicon. However, for optical and micr

Optical Interference Coatings.
Thermal expansion mismatch between the layers of an optical coating and its substrate can cause changes in the shape of a mirror or optical element. It is shown that with knowledge of the linear stress-temperature relationship for each film, one can

Optical coating degradation under laser irradiation can take several forms. Perhaps the most common that is not due to particulates is thermal breakdown, caused by heating of the coating to a catastrophic failure induced by local melting, delaminatio

Laser induced damage can take several forms. Perhaps the most common is thermal breakdown, caused by heating of the coating to a catastrophic failure induced by local melting, delamination, evaporation, or some other change. We demonstrate that micro

A mechanical design technique for optical coatings that simultaneously controls thermal deformation and optical reflectivity is reported. The method requires measurement of the refractive index and thermal stress of single films prior to the design.

Very high-aspect ratio channels may be coated using atomic layer deposition (ALD) due to the unique self-limiting nature of the process. Reactive ion-etched trenches with aspect ratios near 100:1 have been coated [1]–[3]. For optical and microfluid
