The approach does not rely on a Euclidean model in which communication characteristics (e.g., signal strength, data rate, etc.) depend on distance between communicating nodes, and does not necessarily require sampling of communication characteristics in unproductive directions in order to move the routers to preferable locations.

Abstract: The present disclosure is directed at a ruthenium based catalyst for NOx reduction. More specifically, ruthenium based catalysts are used for NOx reduction in an internal combustion engine to reduce NOX to nitrogen, at relatively high conversion and selectivity, using carbon monoxide and hydrogen as reductants. The ruthenium based catalyst has particular utility in exhaust gas recirculation such as in dedicated exhaust gas recirculation (D-EGR) systems.

Abstract: The present invention relates to a method for preparing a catalyst comprising a ruthenium-containing catalyst layer highly dispersed with a uniform thickness on a surface of a substrate having a structure, which comprises first aging a mixed solution of a ruthenium precursor-containing solution and a precipitating agent to form a ruthenium-containing precipitate seeds, secondarily aging the first aged mixed solution to grow the seeds thereby forming ruthenium-containing precipitate particles, and then contacting the particles with a substrate to deposit the particles on the surface of the substrate. Since the catalyst has a structure in which the round shaped ruthenium-containing precipitate particles are piled to form the ruthenium-containing catalyst layer, it has a large specific surface area. Thus, the catalyst may exhibit excellent catalytic performance in various reactions for producing hydrogen using a ruthenium catalyst.
