A method and system for automatically generating a scoring model for scoring a speech sample are disclosed. UMTS services are transmitted to a WLAN through a UMTS repeater tuned to receive services addressed to registered IDs and transmit these services to that WLAN having mobile stations registered with the UMTS. A connection port is electrically connected to the chargedischarge unit, the control unit, the driving unit and the light source so as to be connected with an electric appliance such as an energy generating device. The side assemblies joined by a hinge at one end and positioned over the two side walls of the cell culture cassette. The method further comprises the step of operating the at least two light sources such that the color coordinates of the light emitted from the at least two light sources are maintained over time within a first, bounded interval, and the luminous intensity of the light emitted from the at least two light sources is maintained over time within a second, bounded interval.
