Abstract: The present invention is directed to a process for evaluating corrosion resistance of coated metals substrates, such as autobodies at accelerated rate. An anode and cathode coated with protective coating being tested are exposed to an electrolyte in a chamber of a corrosion resistance evaluator. These coatings are provided with predetermined and standardized defects, such as micro-holes to accelerate the corrosion of the underlying metal substrate in a predictable and repeatable manner. The coated cathode/anode pair is subject to a start-up period followed by series preset DC voltages modulated in a stepwise manner for preset durations that are interspaced with recovery periods. The impedance data collected are then used to arrive at the corrosion performance resistance of the coating applied over the cathode/anode pair. The foregoing evaluator substantially reduces the time required to test corrosion from several days (40 plus days) to few days (about two days).

Abstract: The invention discloses Physical Cell Identity (PCI) allocation in a cellular network. Radii of an inner boundary circle of a first and second cell are each estimated according to a cell distance relation model. Signal strengths within the inner boundary circles of the first and second cells are each greater than a first threshold. Then radii of an outer boundary circle of the first and second cell are each estimated according to the cell distance relation model. The signal strengths within the outer boundary circles of the first and second cells are each greater than a second threshold, where the second threshold is lower than the first threshold. The second cell is allocated a PCI based on a distance relation between the first cell and the second cell.

Abstract: A method and system for controlling a temperature of an exhaust gas being introduced to a catalyst is provided. Using an adjustable flow controller, an adjustable amount of tempering fluid is provided to the exhaust gas prior to the exhaust gas proceeding to the catalyst. A sensor senses a parameter indicative of a temperature of the exhaust gas being introduced to the catalyst. A computer processor uses a relationship to relate the parameter to an adjustment of the adjustable flow controller that will adjust the amount of tempering fluid provided to the exhaust gas and change the temperature of the exhaust gas being introduced to the catalyst toward a target temperature. Adjustment of the adjustable flow controller is initiated by the computer processor to change the flow of the tempering fluid, and the relationship between the parameter and the adjustment of the adjustable flow controller is updated.
