Propagate changes

Since the rate-constants calculated by Kunitake and Takarabe for styrene contain unknown contributions from at least three propagators, they cannot be included in our final table of results. It is also evident that the variation of the rate-constants with temperature cannot provide any useful information, because the relative contributions from the different propagators change with temperature.

The issue of bugs introduced by developers who did not notice dependencies between entities and failed to propagate changes correctly was named by Pamas and Brooks as software aging . 

The electrostatic potential across cell membranes plays important roles in transport and in cell signaling. Muscle contraction is stimulated by depolarization of the cell membrane. Nerve cells communicate with other cells via propagated changes in membrane potential. Also the potential across membranes of intracellular organelles, such as mitochondria, can be central components of the function of the organelles. 

REACH seeks to address universal challenges on the lack of risk data and the poor quality of many safety data sheets (SDS). With its dominant role in the global chemicals market, the EU could be ideally situated for propagating change through international supply chains. Even the prospect of REACH has already catalysed change within the chemical industry. 

Mode of operation An integrator tool must operate incrementally rather than batch-wise. It is used to propagate changes between interdependent documents. This is done in such a way that only actually affected parts are modified. As a consequence, manual work does not get lost (in the above example the elaboration of the simulation model), as it happens in the case of batch converters. 

Time of activation In single user applications, it may be desirable to propagate changes eagerly. This way, the user is informed promptly about the consequences of the changes performed in the respective documents. In multi user scenarios, however, deferred propagation is usually required. In this way each user keeps control of the export and import of changes from and to his local workspace. 

A key and unique feature of our approach consists in its support for round-trip process evolution. To realize this approach, we have to work both bottom-up and top-down we learn from actual performance (bottom-up) and propagate changes to process definitions top-down. In contrast, most other approaches are confined to top-down evolution. For example, in [727, 764, 772, 792], the process definition has to be created beforehand, while we allow for executing partially known process definitions. 

At the ductile-to-brittle transition, crack propagation changes from unstable to stable crack growth. Both at low and high speeds, a ductile-to-brittle transition can be observed. The high-speed transition cannot be obtained by extrapolating from the low-speed data. Also, the low-speed transition is not a discontinuous transition and depends on different structural parameters, like...

The mapping framework is used to map between different representations of the viewpoints of a product. The mappings can be used to check the consistency of the different viewpoints of a product, or to propagate changes from one viewpoint to the other.
