An appliance development toolkit includes an editor configured to create one or more test scripts having steps with each step being separated from its adjacent steps by a transition condition. The radio receiver has a first reception path for processing of the first section and a second reception path for processing of the second section. The device includes a strap with fasteners at each end that are matingly engageable with each other to secure the lid to the container. In the prosody modification value search, a prosody modification value sequence that minimizes a modified prosody cost is searched for. When in use, the positioning portion partially extends through the through hole, selectively extends through one of the holes, and then is positioned by a force of the resilient section, such that the extension-length of the second support member relative to the first support member is adjusted. Bandgap engineering may be achieved by the method by adjusting reaction parameters of the GSMBE process and the relative concentrations of the constituents of the quaternary alloy films.
