Abstract: Methods and systems for identifying stormwater management opportunities in accordance with embodiments of the invention are disclosed. In one embodiment of the invention, a method for identifying stormwater management opportunities comprises gathering spatial data for a region; rasterizing the spatial data into a set of raster data layers; forming a plurality of benefit maps using subsets of the set of raster data layers, wherein the plurality of benefit maps corresponds to a plurality of benefit categories; generating an opportunity map by combining a subset of the plurality of benefit maps using weights corresponding to the plurality of benefit categories; and displaying the opportunity map on a user interface.

Abstract: Systems and methods in accordance with embodiments of the invention are software models that present information in a format directly usable by stormwater managers to inform annual program decisions and consistently evaluate the effectiveness of stormwater management actions. Stormwater modeling systems in accordance with many embodiments of the invention provide a tool that can be used by stormwater managers to estimate load reductions. In a number of embodiments, a user interface is provided that streamlines user input data requirements. In this way, the stormwater modeling system can extend the utility of event-based model inputs, generate results that inform management decisions, and demonstrate progress using a common scalable unit.

Abstract: Solar panels and assembled arrays thereof include a collection of relatively compact, high-capacity power units. Optical components of each power unit include a front window or surface glazing, a primary mirror, secondary mirror and receiver assembly. Primary and secondary mirrors are defined by respective perimeters, at least a portion of which may be substantially coplanar and in contact with the front window. Some primary mirrors are configured with a perimeter of alternating full and truncated sections, and are curved to a base portion forming a pilot hole therein. Receiver assembly mechanical components include an alignment tube for mating with the primary mirror's pilot hole and for housing a photovoltaic solar cell. A base plate provided adjacent to the alignment tube serves to radiate heat emitted by the solar cell, and in some embodiments an additional heat sink provides further passive cooling.

Abstract: Ultra-compact concentrators and illuminators that approach the thermodynamic limit to optical performance can be realized with purely imaging strategies. Two-stage reflector systems where each optical surface is tailored to eliminate one order of aberration—so-called aplantic designs are described. The contours are monotonic functions that can be expressed analytically—important in facilitating optimization studies and practical fabrication. The radiative performance of the devices presented herein is competitive with, and even superior to, that of high-flux nonimaging systems. Sample results of practical value in solar concentration and light collimation are presented for systems that cover a wide range of numerical aperture.
