Abstract: A modular, electrically chargeable protective barrier that is structured to be coupled to a temporary fence panel is disclosed. The barrier includes a frame comprising multiple side vertical conductive support members and multiple horizontal conductive support members. The frame is electrically chargeable. The barrier includes multiple exposed conductive wires spanning a distance between the side vertical conductive support members. The exposed conductive wires are electrically chargeable, and a charge passes from the wires to the frame. The barrier includes a conductive bracket and a non-conductive bracket.

Abstract: Systems and methods for model evaluation. A model is evaluated by performing a decomposition process for a model output, relative to a baseline input data set.

Abstract: Systems and methods for model evaluation. A protected class model that satisfies an accuracy threshold is built by using: data sets for use by a modeling system being evaluated, and protected class membership information for each data set. A target for the protected class model is a protected class membership variable indicating membership in a protected class. Each predictor of the protected class model is a predictor of an evaluated model used by the modeling system. A target of the evaluated model is different from the target of the protected class model. Each predictor is a set of one or more variables of the data sets. For each predictor of the protected class model, a protected class model impact ranking value and a modeling system impact ranking value are determined.

Abstract: Systems and methods for generating and processing modeling workflows are disclosed. In some examples, a reference distribution of scores generated by a model is determined. The reference distribution of scores is recorded in a structured database. One or more unexpected scores are detected during execution of the model. To detect the one or more unexpected scores, a production distribution of scores is compared with the reference distribution of scores recorded in the structured database. The production distribution of scores is generated by the model for a production input data set. An alert is then provided to an external system, when an alert condition is determined to be satisfied based on the comparison. The alert indicates detection of the one or more unexpected scores.

Abstract: A brine electrolysis system for producing pressurized chlorine and hydrogen gases. In its basic configuration, the brine electrolysis system may comprise: two liquid storage tanks for storing two liquid reactants; a tank having two interior spaces separated by a diaphragm for receiving the liquid reactants; two pumps for regulating the flow of the liquid reactants from the liquid storage tanks to the interior spaces of the tank, two open-bottom cylinders for storing and dispensing two gases; an electrolysis stack assembly for converting the liquid reactants into two gases; and two submersible pumps for pumping each liquid reactant into an electrolysis stack assembly. Each open-bottom cylinder may comprise a float sensor for determining the amount of fluid entering its cylindrical space. The system may further comprise controllers for regulating ionic concentrations within the two interior spaces. Dispense lines and valves may be utilized to release the gases.

Abstract: An in-water refueling system for unmanned undersea vehicles with fuel cell propulsion. The in-water refueling system may store a liquid such as water at constant pressure and may dispense gases such as hydrogen or oxygen for refueling. In its basic configuration, the in-water refueling system may comprise a tank with an interior space for storing the liquid; a pump for regulating the flow of liquid into the interior space of the tank; an electrolysis stack assembly for converting the liquid into one or more gases; and open-bottom cylinders for storing and dispensing the gases. Each open-bottom cylinder may comprise a float sensor for determining the amount of fluids entering its cylindrical space. The in-water refueling system may further comprise a controller for regulating a temperature and a fluid pressure in the tank. Dispense lines and valves may be utilized to release the gases from the tank.
