Abstract: A system, method and computer program product cooperate to extract a building footprint from other data associated with a property. Imagery data of real property is input to a computing device, the imagery data containing a plurality of parcels. A processing circuit detects contrasts of candidate man-made structures on a parcel of the plurality of parcels. The candidate man-made structures are then associated with the parcel. A building footprint is then extracted by distinguishing a man-made structure on said parcel from natural terrain, recognizing that man-made structures when viewed from above generally show a strong contrast from background terrain. Remaining candidate man-made structures are removed by observing that they having features inconsistent with predetermined extraction logic.

Abstract: Computer-based systems and methods are disclosed for modeling and predicting flash flood risks for real estate properties. In some embodiments, the systems and methods can predict flash flood risks for real estate properties by considering a variety of factors, including watershed hydrology characteristics, land surface characteristics, meteorological characteristics, and/or property characteristics. In some embodiments, the systems and methods can improve determination of investment metrics or automated valuations by considering flash flood risks in determining the investment metrics or automated valuations.

Abstract: An apparatus, method and computer program storage device determine a composite hazard index. An interface receives a first risk score for a first hazard and a second risk score for a second hazard. The first risk score is in a first range of scores and the second risk score is in a second range of scores. A processing circuit emphasizes at least some scores in at least one of the first range of scores and the second range of scores. The processing circuit also normalizes the first risk score with respect to the first range of scores and second range of scores, and normalizes the second risk score with respect to the first range of scores and second range of scores. The processing circuit also combines a normalized first risk score with a normalized second risk score to form at least a component of a composite risk index. The first risk score and second risk score being specific to a common property.

Abstract: Disclosed is a bipolar electrolyzer having a plurality of individual electrolytic cells electrically and mechanically in series with a bipolar element between pairs of adjacent individual cells. The bipolar element has an anodic side with anodes of the first electrolytic cell of a pair of electrolytic cells depending therefrom, and a cathodic side with the cathodes of the second electrolytic cell of the pair of electrolytic cells depending therefrom. The anodic side of the bipolar element has an acidified alkali metal chloride resistant valve metal surface, and the cathodic side of the bipolar element has an alkali metal hydroxide resistant transition metal surface.

Abstract: Disclosed is an electrolysis cell and method of operation in which metal anodes (preferably titanium) provided with an electrically conducting electrocatalytic coating in an anode compartment face diaphragm covered metal cathodes in a cathode compartment, in which the anodes are spaced from an imperforate valve metal separating partition by a separating wall behind which the anolyte can recirculate downward, the anodic gases rising in the anode compartment "gently" circulate the anolyte and the gases are discharged into a brine box above the anode compartment near the center thereof and the anolyte recirculates downward near at least one end of the anode compartment; and a method of operation which provides circulation from front to back of the anode compartment and from center to sides of the anode compartment and means for adding new diaphragm material to the circulating anolyte to deposit said new diaphragm material on the diaphragms and methods of determining when and how much new diaphragm material to ad

Abstract: Liquid if present in a gas stream is detected by expanding the volume per unit weight of the gas in a vessel to the point where liquid collects in the bottom of the vessel and weighing the liquid.

Abstract: Disclosed is a bipolar electrolyzer having a horizontal hydrogen channel separate from the catholyte chamber. There are apertures between the horizontal hydrogen channel and the catholyte chamber to enable catholyte gas, i.e., hydrogen, with entrained cell liquor, to enter the channel. At one end of the channel is a gas disengaging chamber. The gas disengaging chamber includes a catholyte gas deflector interposed between the outlet of the horizontal channel and the interior of the disengaging chamber, hydrogen recovery means, and catholyte liquor recovery means. In the operation of an electrolytic cell as disclosed herein, catholyte gas, i.e., hydrogen gas with entrapped catholyte liquor, is removed from the catholyte chamber to the horizontal channel. The catholyte gas is then transported through the horizontal channel to the outlet of the horizontal channel and into the disengaging chamber.
