The business logic implements a web service consumer or a web service provider business logic. An environment indicator analyzer application executing on the data processing system analyzes the multiple environment indicators received at the data processing system according to the environmental sensitivity profile and determines control signals for adjusting multiple environmental control systems that control the particular environment. The resultant ceramic-bearing bodies may be used as effective sensors of reducing gas species in such applications as automobile and industrial emissions. A processor selects a precompiled hardware template from a plurality of the precompiled hardware templates in the memory for loading onto the re-configurable logic device based at least in part on the associated performance characteristics of the data processing operations defined by the precompiled hardware templates.
