Abstract: An example of a system for use in collecting fluid from a gas stream includes one or more collection panels and a frame for arranging the panel(s). Each of the collection panel(s) may comprise an emitter electrode assembly member, comprising one or more emitter electrodes, physically attached to an electrically insulated from a fluid collection member comprising one or more collection electrodes. The frame may be sized and shaped to be disposed near a gas outlet or a duct. An example of a method for collecting fluid from a gas stream includes providing the collection panel(s) disposed in a path of the gas stream; providing the gas stream; generating and maintaining a voltage at the one or more emitter electrodes of each of the collection panel(s); and collecting an amount of the fluid from the gas stream with the one or more collection panels.

Abstract: An example of a species collection system includes a plurality of spaced-apart electrically conductive collectors and a plurality of emitter electrodes. In some embodiments, at least one emitter electrode is disposed between adjacent ones of the collectors. In some embodiments, the at least one emitter electrode extends beyond the collectors (e.g., in at least one dimension). Collectors may be aligned to a direction of gas flow from an outlet (e.g., of a cooling tower) to facilitate collection while minimizing interference with the gas flow. Different emitter electrodes may be maintained at different voltages. In some embodiments, collectors are attached to a collector frame and emitter electrodes are attached to emitter frame(s) that are electrically insulated from the collector frame. Collectors may span a gas outlet (e.g., of a cooling tower) and emitter frame(s) may be positioned outside of the collectors (e.g., and outside of a periphery of the gas outlet).

Abstract: An optimization framework for spectrum sharing in white space bands formulates an objective function as a linear function of channels and power levels, and constructs a linear set of equations based on a general graph model according to constraints, including spectrum usage regulations and/or resource re-use constraints. The optimization framework provides joint power control and channel assignment where the solution is implemented by an algorithm that allocates time/power/channel to each network to avoid interference while re-using time and/or frequency resources. The solution allocates a fair and orthogonal portion of time on each channel for a certain power level to the networks. The solution can be implemented by a central entity having at least location information of the networks and, upon solving the optimization problem, signals scheduling information of each channel assigned.

Abstract: A method and system for parallel resource management in white space bands may use transmit power control and channel set assignment. Channel sets and corresponding network sets for each of L power levels may be assigned for N networks sharing K number of channels. The input may be location information for each of the N networks. The output may be updated channel sets and corresponding network sets for each of the L power levels. The method may assign maximum networks to channel sets with larger power values. The network sets may be constructed such that a number of channels in a corresponding channel set is larger than a maximum node degree of a corresponding interference graph. The method may further take into account re-use possibilities for channels among networks and may accordingly increase spectrum utilization.

Abstract: A method and system for iterative fair channel assignment may orthogonally assign K channels to N wireless networks such that neighbor networks operate over different frequencies. The iterative fair channel assignment may include an orthogonal channel assignment that may not only assign a fair share of spectrum to each network but may also increase the spectrum re-use by assigning channels to as many networks as possible.
