Abstract: 4-pyrrolylpyridine, a novel anion sensor, displays a substantial color loss upon addition of sodium sulfite in aqueous solvents. A variety of anions were tested, including halides, phosphates, sulfates, and hydroxide, but all solutions remained unchanged aside from the sulfite, which displayed bleaching. Described here is a method for which the exact concentration of sulfites in a consumer product can be determined. The test is sensitive over a broad range of sulfites, from 0.84 ppm to over 10,000 ppm, and is accurate with a standard deviation of ±0.01 ppm.

Abstract: A system and method for automated routing of people and materials from one location to another based on automated vehicle technology are applied to bus transit, ridesharing and car sharing, and on multiple modes of delivery, including rail, water, road and air. An optimal transit algorithm uses Degree of Circuity (DOC) and Maximum Degree of Circuity (Max DOC) to refine transit network design and scheduling. Max DOC and computed shortest travel times are used to define the maximum acceptable travel time for each passenger or package. Using those maximum acceptable travel times for passengers and/or packages as constraints, optimal routings are developed for each primary transport hub, using a Simulated Annealing (SA) algorithm. The SA algorithm may be used as a basis for optimal flexible feeder bus routing, which considers relocation of buses for multiple primary transport hubs and multiple primary transport vehicles.
