A data processing system is provided that includes applications, databases, encryption engines, and decryption engines. A concave region, formed in an approximate arc shape in cross-section, is arranged on an end face of the elastic layer in a longitudinal direction of the pressure roller. A GUI element may also be included in the program, and the binding configured for the data source component may be associated with the GUI element in response to user input. Such a system enables fast and accurate determination of the resolution and alignment of an imaging system using an inexpensively produced test target together with an arbitrary image viewing program. A system to decrease emission of mercury; comprises a combustion zone that is controlled to generate a flue gas comprising fly ash with enhanced unburned carbon and that produces vaporized mercury; and a post combustion zone to cool the flue gas to collect fly ash with enhanced unburned carbon with absorbed mercury. As a result of the disclosed method, the amount of data that can be transmitted through the interface is maximized.
