Abstract: A data storage method includes partitioning a data into an array having a plurality of data blocks and storing the data blocks across a plurality of storage nodes. Parity blocks are encoded based on the data array by performing a shift operation on the data array to produce a shifted array and performing an exclusive OR (XOR) operation on the elements in each row of the shifted array to produce a parity block. The method further includes storing the parity blocks across a plurality of the storage nodes. Systems are configured to recover data from a data array in the event that the data array is at least partly inaccessible.

Abstract: We provide a method of compressing a data stream for transmission, including: generating a data sequence representing a received data stream, generating a plurality of data substreams, each comprising a portion of the data sequence, identifying a formal concept defining a dependency between a first one of the data substreams and one or more further ones of the data sub streams that are dependent on the first data substream, removing those dependent data sub streams from the plurality of data sub streams, and transmitting the remaining data sub streams, and a method of reconstructing a data stream at a receiver, including: receiving a received data sequence representing a received data stream, identifying that a substream has been removed from the data stream prior to transmission, identifying a formal concept definition for regenerating the removed substream based on an identified substream of the received data sequence, regenerating a data substream using the formal concept definition and the identified sub stream of the received data sequence, and adding the regenerated data substream to the received data sequence.

Abstract: The antimicrobial agent includes at least one two-dimensional metal carbide layer. The two-dimensional metal carbide has the formula Tin+1CnTx, where T represents a terminal functional group and x represents the number of terminal functional groups. The two-dimensional metal carbide is preferably Ti3C2Tx. The terminating group may be oxygen, hydroxide (OH), fluorine or combinations thereof. The antimicrobial agent may be used as a two-dimensional metal carbide antimicrobial membrane (10) or filter for removal of harmful bacteria, such as E. coli and B. subtilis. A stack of two-dimensional metal carbide layers (14) may be supported on a polymer filter substrate (12), such as a polyvinylidene fluoride (PVDF) supporting substrate.

Abstract: The hybrid desalination system (10) includes a reverse osmosis filtration system (14), a forward osmosis filtration system (18), and a multi-effect distillation system (16). A condenser (12) receives seawater (S) and produces cooled seawater (CS). The cooled seawater (CS) is filtered by the reverse osmosis filtration system (14), which outputs a first brine reject stream (BR1) and a permeate stream (P). The multi-effect distillation system (16) outputs a second brine reject stream (BR2). A feed side (20) of the forward osmosis filtration system (18) receives the first brine reject stream (BR1), and the second brine reject stream (BR2) is received by the draw side (22), which outputs diluted brine (DB). The multi-effect distillation system (16) is in fluid communication with the forward osmosis filtration system (18) and recycles the diluted brine (DB). The multi-effect distillation system (16) outputs a return condensate (RC) and a pure water distillate (D).

Abstract: The robotic upper limb rehabilitation device assists in rehabilitation of an upper limb of a human patient recovering from a stroke or the like. The device is an exoskeleton having an articulated shoulder assembly having five degrees of freedom, including at least two degrees of freedom simulating inner shoulder movement. An upper arm member is pivotally attached to the shoulder assembly, and a forearm assembly is pivotally attached to the upper arm member. An inflatable handgrip is pivotally attached to the forearm assembly. A robotic control unit receives signals from sensors and is configured to activate actuators attached to the exoskeleton to assist upper limb movement when required, or to permit the exoskeleton to conform to upper limb movement when no assistance is required.

Abstract: The geo-security method and system uses spatio-temporal radio channel information during authentication to grant permission to access, use and/or operate the intended device. The geo-security method and system uses a wideband radio channel impulse response (or transfer function of radio channel) from antenna of RF source to antenna of a RF receiver at the device position to determine the legitimacy of the intended device's location.

Abstract: The method for low temperature microencapsulation of phase change materials or other components includes the following steps: (a) preparing a phase change emulsion including droplets of at least one active phase-change material in water with a surfactant; (b) adding a monomer of at least one encapsulating agent; (c) introducing the phase change emulsion into a UV reactor while stirring the emulsion; and (d) initiating the photo polymerization of monomers using at least one UV lamp inside the UV reactor for photo polymerization until the phase change material is encapsulated within a polymeric shell to form microcapsules. The microcapsules obtained by this process may have a diameter between about 0.5 to about 2 μm. Other sizes can also be obtained by changing stirring speed of the emulsion.

Abstract: A composite material for electromagnetic interference shielding is provided. The composite material comprises an electrically conductive microscale films based on Transition Metal Carbo-Chalcogenides (Nb2S2C) stack layers. The stack is effective to provide a substantial electromagnetic interference (EMI) shielding. Once decorated with special metallic nanoparticles made mainly with noble metals including Au, Ag and Pd, this efficiency against the EMI is even enhanced. The disclosed technology introduces a special coating that can be applied to electronic devices and materials. This coating acts as a shield that protects these devices from different types of interference that can disrupt their signals and performance. This coating can work on devices that bend or move, and effectively blocks interference across a wide range of frequencies. As such, the disclosed technology keeps devices working smoothly even in places with a lot of electronic “noise” without restricting their flexibility or range of use.
