Various technologies and techniques are disclosed for providing a framework with a common set of domain-specific entity identifier types that object models representing conceptually similar entities from a domain can use to correlate to model-specific object instances. The terminal electrodes of the chip component are adhered to the pads by a conductive adhesive and an insulating adhesive is provided between the pads. The last optical element is substantially without refracting power and has no curvature or only slight curvature. A first proper subset of the first candidate antenna configurations is selected when the quality data corresponding to the first candidate antenna configurations compares unfavorably to the quality threshold; and second candidate antenna configurations are generated, based on the first proper subset. The pressure-receiving area receives pressures from both the first and second pressure members. Optionally, the porous coating may be further coated with a catalyst for fuel cell applications.
