Abstract: A consensus-based decentralized multi-robot approach is presented for reconstructing a discrete distribution of features, modeled as an occupancy grid map, that represent information contained in a bounded planar 2D environment, such as visual cues used for navigation or semantic labels associated with object detection. The robots explore the environment according to a random walk modeled by a discrete-time discrete-state (DTDS) Markov chain and estimate the feature distribution from their own measurements and the estimates communicated by neighboring robots, using a distributed Chernoff fusion protocol. Under this decentralized fusion protocol, each robot's feature distribution converges to the ground truth distribution in an almost sure sense.

Abstract: Composite material can include a matrix material, a fiber dispersed in the matrix material, and an ultraviolet (UV)-light sensitive mechanophore grafted to a surface of the fiber. A method for making a fiber-reinforced polymer composite can include contacting a fiber in a first solution, rinsing and then drying intermediate fiber, contacting dried fiber in a third solution, rinsing, and then drying the rinsed fiber thereby generating functionalized fiber that is sensitive to ultraviolet light. The functionalized fiber can be combined with a polymer matrix material, cured, and irradiated, thereby generating a fiber-reinforced polymer composite.

Abstract: Multi-stage distributed beamforming for distributed mosaic wireless networks is provided. Embodiments described herein present systems, devices, and methods that provide increased range, data rate, and robustness to interference and jamming. A distributed mosaic wireless network includes a transmitter, a receiver, and one or more distributed clusters of radios referred to herein as mosaics or relay mosaics. Each mosaic consists of several distributed, cooperative radio transceivers (e.g., mosaic nodes) that relay a signal sent by the transmitter towards the receiver. In some embodiments, a single-stage beamforming technique is implemented whereby the transmitter sends a signal to a first mosaic, which then relays this signal by beamforming to the receiver. In some embodiments, a multi-stage beamforming technique is implemented whereby the transmitter sends a signal to a first mosaic, which then relays this signal by beamforming to a second mosaic, which then relays this signal by beamforming to the receiver.

Abstract: The performance of quantum key distribution by systems and methods that use wavelength division multiplexing and encode information using both wavelength and polarization of photons of two or more wavelengths. Multi-wavelength polarization state encoding schemes allow ternary-coded digits, quaternary-coded digits and higher-radix digits to be represented by single photons. Information expressed in a first radix can be encoded in a higher radix and combined with a string of key values to produce a datastream having all allowed digit values of that radix in a manner that allows eavesdropping to be detected without requiring the sender and receiver to exchange additional information after transmission of the information.
