Abstract: Methods, systems and computer program products to measure system re-taskability are disclosed. The methods, systems and computer program products may be used in the design of a new or redesign of an existing System of Systems (SoS). Systems re-tasking (aka substitutability or stand-in redundancy) is the process of using different systems to substitute for non-operational systems to meet required functionality, or using multi-function systems to fulfill higher-priority tasks. This ability can increase the overall operational availability of the SoS; it can also increase the adaptability and resilience of the SoS to unknown or changing conditions. The disclosed methods, systems and computer products include simulating an SoS over time, replacing systems that become non-operational (or damaged) with systems that can fulfill the same capability in order to maximize the SoS availability.

Abstract: A neuromorphic machine and method of determining an optimum value. The neuromorphic machine comprises a plurality of spiking neurons and a plurality of blocking neurons. The plurality of spiking neurons are configured to receive a plurality of input signals representing a plurality of input values and to implement objective functions on the plurality of input values. The plurality of blocking neurons are configured to receive the plurality of input values and output from the plurality of spiking neurons as input and to provide an output signal representing an optimum value corresponding to at least one of the plurality of input values.

Abstract: Methods, systems and computer program products to evaluate or assess strategies for operating and designing complex systems, including systems of systems, are disclosed. The methods, systems and computer program products provide describe and evaluate the behavior of systems in real-world environments where future conditions are highly uncertain are disclosed. The present disclosure identifies a set of important strategies, a set of concomitant actions, and a set of environmental conditions that form the basis of strategic change rules. These rules can be incorporated in a simulation to modify the behavior of the simulated system.

Abstract: Methods, systems and computer program products to measure the adaptability of complex systems, including systems of systems, are disclosed. The methods, systems and computer program products provide rigor and defensibility to the analysis and assessment of adaptability. As a result, systems can be designed or acquired that are intrinsically more adaptable and better able to respond to changing environments.

Abstract: A sound synthesis method for modeling and synthesizing dynamic, parameterized sounds. The sound synthesis method yields perceptually convincing sounds and provides flexibility through model parameterization. By manipulating model parameters, a variety of related, but perceptually different sounds can be generated. The result is subtle changes in sounds, in addition to synthesis of a variety of sounds, all from a small set of models. The sound models can change dynamically according to changes in the simulation environment. The method is applicable to both stochastic (impulse-based) and non-stochastic (pitched) sounds.
