Abstract

A method for automatically generating an anomaly detection system for a cyber-physical system. A directed graph is obtained from the cyber-physical system's design. The directed graph has nodes representing control components of the cyber-physical system that control physical processes. The directed graph is traversed to determine associated control components from the nodes and edges based on predefined parameters. Invariants are derived from the associated control components based on physical/chemical properties governing them. The invariants define conditions for detecting anomalies of the physical processes and are configured as an executable invariant computer program. Upon execution, the anomalies are detectable in response to determining that measurements from the control components have violated the invariant conditions.

Abstract

Composite anti-fouling coatings and associated systems and methods are generally described. In some aspects, a system comprises a substrate, a composite coating disposed on at least a portion of the substrate, and a fluid comprising one or more foulants, where the composite coating is configured to be in physical contact with the fluid during use. The composite coating may comprise a first region comprising a first material and a second region comprising a second material that is different from the first material. According to some embodiments, a full- spectral Hamaker constant associated with the composite coating and the fluid (i.e., based on average optical properties of the first and second materials of the composite coating) is relatively low, and the van der Waals (vdW) force between the composite coating and the one or more foulants is, therefore, correspondingly low. Under some conditions (e.g., high temperature and/or high pressure conditions), intermolecular interactions between the composite coating and the one or more foulants may be dominated by the vdW force, and a relatively low vdW force may reduce the likelihood of the one or more foulants adhering to and/or otherwise being deposited on the composite coating. By selecting materials for the composite coating that result in a relatively low full- spectral Hamaker constant, fouling of the composite coating may thus be reduced or even eliminated. In some cases, two or more materials with optical properties (e.g., refractive indices, frequency-dependent dielectric response values) that, when averaged, are substantially similar to those of the fluid across a spectrum of frequencies or wavelengths may advantageously be associated with a relatively low full- spectral Hamaker constant.

Abstract

Composite anti-fouling coatings and associated systems and methods are generally described. In some aspects, a system comprises a substrate, a composite coating disposed on at least a portion of the substrate, and a fluid comprising one or more foulants, where the composite coating is configured to be in physical contact with the fluid during use. The composite coating may comprise a first region comprising a first material and a second region comprising a second material that is different from the first material. According to some embodiments, a full- spectral Hamaker constant associated with the composite coating and the fluid (i.e., based on average optical properties of the first and second materials of the composite coating) is relatively low, and the van der Waals (vdW) force between the composite coating and the one or more foulants is, therefore, correspondingly low. Under some conditions (e.g., high temperature and/or high pressure conditions), intermolecular interactions between the composite coating and the one or more foulants may be dominated by the vdW force, and a relatively low vdW force may reduce the likelihood of the one or more foulants adhering to and/or otherwise being deposited on the composite coating. By selecting materials for the composite coating that result in a relatively low full- spectral Hamaker constant, fouling of the composite coating may thus be reduced or even eliminated. In some cases, two or more materials with optical properties (e.g., refractive indices, frequency-dependent dielectric response values) that, when averaged, are substantially similar to those of the fluid across a spectrum of frequencies or wavelengths may advantageously be associated with a relatively low full- spectral Hamaker constant.

Abstract

Disclosed is a method for enhancing security of a system network. The system network includes one or more devices. The method involves building an agent network comprising one or more security devices. The one or more security devices are designed to appear to an external party as at least one of hidden and indistinguishable from the one or more devices of the system network, and to provide one or more enhanced security operations. The method also involves connecting the agent network to the system network thereby incorporating the enhanced security operations into the system network.

Abstract

Structures, methods of tuning and methods of fabrication for a dynamically reconfigurable color-tuneable device are provided. The device includes a functional layer sandwiched between a top electrode layer and a bottom electrode layer. The top electrode may include a transparent electrode material. The functional layer includes a first layer of mobile highly reflective elements and a second layer of an amorphous or mesoporous dielectric material. The device can be color-tuned by providing for a first predetermined time duration a first bottom electrode voltage to the bottom electrode which is positive as compared to a first top electrode voltage simultaneously applied to the top electrode to tune a viewable color of at least a portion of the top electrode from a first color to a second color. The color originates from the movement of mobile highly reflective elements to the amorphous or mesoporous dielectric layer when an electric field is applied.
