This method is based on the refinement of system global requirements and their projection on the system components to formalise local properties to be proved by the model checker.
The refinement principle of systems states that any system S in ({mathfrak {U}}) can be deductively specified and analyzed with increasing details at different layers, (0 le k le n), from the top down.
Malaria elimination programs should support the implementation and refinement of information systems to support surveillance and response and ensure political and financial commitment to maintain the systems and the human resources needed to run them.
What we said: The crudeness and simplicity of its structure is juxtaposed with the refinement of its systems.
The facile chemistry described and significant cellular responses observed suggest the usefulness of these materials in a variety of in vitro and ex vivo biologic investigations, and may aid in the design or refinement of material systems for a range of tissue engineering approaches.
Further refinement of the systems should focus on both increasing human and financial resources and improving management practice.
An important outcome of the evidence-gathering phase was the building and refinement of information systems that informed – and continue to inform – many aspects of strategic direction.
Second, and relatedly, the quality improvement literature conceptualizes the process of capturing information through the refinement of measurement systems as a matter of applying a set of timeless scientific principles.
Ongoing discussions between coordinating bodies, such as OFFLU, database designers, and funders, might help improve efficiency and refinement of reporting systems and also ensure resource alignment across high-priority surveillance and reporting.
Developmental changes in performance on memory tasks involving semantically related stimuli over childhood and adolescence appear to result from the concurrent refinement of neural systems for recollection and for semantic elaboration and controlled aspects of episodic memory retrieval.
