Generating a Multiple-Prerequisite Attack Graph

In one aspect, a method to generate an attack graph includes determining if a potential node provides a first precondition equivalent to one of preconditions provided by a group of preexisting nodes on the attack graph. The group of preexisting nodes includes a first state node, a first...

GenX: Configurable Capacity Expansion Model

Classic methods and metrics used to inform decision-making for power systems planning include capacity expansion models and levelized cost of electricity (LCOE) calculations to compare the economics of individual technologies. While these classic approaches offer information about different...

High Peak Power Optical Amplifier

A method and apparatus for providing a high peak power optical beam. The method includes interleaving pulse trains of different wavelengths and spatially and temporally overlapping the different wavelengths to produce an amplified output beam with very high peak power.

Hybrid Transmission Reflection Grating

Reflection gratings require large size due to their small incident angles (or a grazing-incidence geometry) and they are sensitive to the misalignment or irregularities (non-flatness) in the surface. Also, in transmission gratings, there are problems of high absorption and low efficiency especially...
