Under the present invention, when an error condition for the computer system is identified, settings for a series of demographical factors of the computer system are determined. Voice commands are passed through a user-command predictor and integrated with a graphical user interface control panel to allow hands-free operation. Polish stops are provided in the multilayer structure before polishing the surface, the hardness of the polish stop material being greater than the hardness of the material that needs to be removed. By using the heat transfer theorem, the disclosed assembly makes the thermistor accurately track the cold junction temperature of the thermopile chip without being in an isothermal condition. A concentrate effluent stream from the electrodeionization unit is filtered in the concentrate filtration membrane; the filtered concentrate effluent stream is provided to concentrating compartments of the electrodeionization unit. With such a correcting process, a high-quality image free of striped artifacts and inclination differences of main scanning lines can be recorded on the photosensitive film.
