摘要： Methods and systems for aggregating points into segments to facilitate measurements relating to GIS polylines and/or polygons are provided. According to one embodiment, a request for information is received regarding a shape representing a geographic feature displayed within a geographic information system (GIS) application. One or more measurement segments are programmatically identified by selecting multiple measurement vertices from a set of points associated with the shape based on one or more predetermined selection criteria. The remaining intervening points of the set of points not selected as measurement vertices define sub-segments of the measurement segments. A length of each of the measurement segments is then calculated and displayed by summing corresponding sub-segments.

摘要： A system, composition and method for controlling fracture grown in the extraction of geothermal energy from an underground formation includes (i) introducing a first fracking fluid into an underground formation; (ii) introducing a second fracking fluid into the underground formation; wherein the specific gravity of the second fracking fluid is different from the specific gravity of the first fracturing fluid, thereby controlling the growth of at least one fracture in a downward direction, and wherein the fracking fluid in at least one of steps (i) or (ii) contains proppant particles having a thermal conductivity contrast of at least 5.

摘要： A system for controlling a desuperheater includes a first temperature sensor coupled to a refrigerant discharge gas line of a compressor; and a controller operatively coupled to at least the first temperature sensor, the compressor, and the desuperheater. The controller controls the desuperheater based at least in part on temperature data received from the first temperature sensor.
