Abstract: Systems and methods are provided to implement moving target defense techniques for transportation systems. The moving target defense techniques can randomly change the IP addresses of the nodes associated with both the vehicles and the corresponding control centers. The nodes for the vehicles and the control centers can be “mobile” nodes that use a “care-of” IP address for communications. The care-of address used by the nodes can be updated through a binding update process. During the binding update process, the one node sends the binding update notice (with a new care-of address) to the care-of address of the other node while maintaining its prior care-of address. The node that receives the binding update notice can send a binding acknowledgement back to the node that sent the binding update. Once the binding acknowledgement is received, the prior care-of address can be removed by the node that sent the binding update.

Abstract: A weather forecasting system may receive satellite image samples and identify an updraft and components of the updraft within a cloud. These satellite image samples are collected over time (e.g., at 30 second to 1 minute time intervals). The system may identify an area of rotation and/or divergence at cloud top in a cumulus cloud or mature convective storm over time by comparing the samples and determine a parameter indicative of the updraft based on the area of rotation and divergence. The system may estimate aspects of the environment related to storm development and predict the occurrence of a weather event in the future based on the parameter and generate an output indicative of the occurrence.

Abstract: A memory system performs analog sanitization of memory using a partial programming operation to overwrite existing data taking into account the relative voltage levels in the memory cells. By taking into account the relative voltage levels, the timing of a partial programming operation can be controlled to provide matched voltage levels in the memory cells so that conventional computer forensic techniques for data recovery are ineffective.

Abstract: Various implementations include an electric motor including an annular radial stator, an annular axial stator, and a rotor. The annular radial stator has an opening with an inner surface and distributed windings disposed along at least the inner surface of the opening. The annular axial stator has concentrated windings disposed along at least a first side of the axial stator. The rotor includes two or more magnets. Flux from the two or more magnets interacts with one or both of a magnetic field created by the radial stator windings or axial rotor windings. The rotor is disposed within the radial stator opening and the axes of the axial stator and radial stator are coincident with the rotor axis. The flux interacting with one or both of the radial stator magnetic field or the axial stator magnetic field turns the rotor about the rotor axis.

Abstract: A method for radiation hardening flash memory performs accelerated aging on the flash memory by program-erase (PE) cycling the flash memory. Such accelerated aging induces trap states in the tunnel oxide layer of the flash memory, which results in improved ionizing radiation tolerance. The number of cycles used to harden a given memory cell is optimally determined in order to limit effects of the radiation hardening on the reliability of the cell.

Abstract: Due to design variations, process variations, manufacturing variations, and other factors, memory of a certain type manufactured by one manufacturer often exhibits a unique pattern of performance characteristics relative to the patterns of the same type of performance characteristics exhibited by memory from other manufacturers. A system for identifying counterfeit memory is trained to learn the different patterns of performance characteristics for different manufacturers of memory. Thereafter, the system may analyze the performance of a given memory device to determine whether the memory device has been manufactured by a particular manufacturer. Thus, the system is capable of determining whether the memory device is counterfeit (e.g., has been manufactured by an unexpected manufacturer).

Abstract: A weather forecasting system has memory for storing satellite image data and numerical weather prediction (NWP) model data, which indicates predicted atmospheric conditions for a geographic region. At least one processor is programmed to identify a cumulus cloud within the satellite image data and to define a zone of influence around the cumulus cloud. The zone of influence represents a boundary for the NWP model data to be used by the processor for predicting whether the cumulus cloud will produce a weather event (e.g., precipitation, convective storm, etc.) in the future.

Abstract: Cementitious compositions comprising a hydraulic cementitious material, a compound selected from the group consisting of a polyhydroxy aromatic compound, a polycarboxylic acid-containing compound or a salt thereof, ascorbic acid or a salt thereof, or a combination thereof, and a particulate material or a water soluble silicate-containing material that interacts with the compound are described herein. The polyhydroxy aromatic compound can be a water soluble compound having from two to thirty hydroxyl groups. The particulate material can exhibit a particle size distribution, wherein at least about 90% by weight of the particles have a diameter of less than 2 mm. Suitable particulate materials include nanoparticles and microparticles. The cementitious compositions can be used to form building materials. The cementitious compositions are especially suited for inhibiting corrosion of reinforcing steel bars embedded in concrete mixtures. Methods of making and using the cementitious composition are also disclosed.

Abstract: A system for testing memory includes logic that is configured to perform various normal memory operations (e.g., erase, read and write operations) on a memory device and to determine operational parameters associated with the memory operations. As an example, the amount of time to perform one or more memory operations may be measured, or a number of errors resulting from the memory operations may be counted or otherwise determined. One or more of the operational parameters may then be analyzed to determine whether they are in a range expected for counterfeit memory. If so, the logic determines that the memory under test is counterfeit (e.g., is recycled or counterfeit) and provides a notification about the authenticity of the memory. The logic may also estimate the age of the memory based on the operational parameters.

Abstract: An electrically-tunable optical filter has an optical cavity that forms an absorption peak in light that is incident on the filter. The optical cavity includes a layer composed of a material with a high electro-optic coefficient so that the index of refraction of the layer changes in response to a voltage applied by a controller. By adjusting the voltage, the controller can control the index of refraction so that an absorption peak of the filter can be tuned as may be desired without having to alter the physical structure of the filter.

Abstract: Systems and methods are provided to implement a moving target defense for a server computer. The server computer can be provided both a permanent IP address and a temporary IP address. The temporary IP address can be used when communicating with client computers connected to the server computer. The temporary IP address can be dynamically changed at a predetermined interval that can be varied based on conditions at the server computer. An intrusion detection system can be used with the moving target defense systems and methods to identify attacks on the server computer based on the temporary IP address(es) provided by the server computer. When an attack is identified, the corresponding client computer is determined based on the temporary IP address and the client computer is placed on a blacklist that is not provided with new temporary IP addresses when the server computer changes temporary IP address.
