MODAFwas an internationally recognised enterprise architecture framework developed by the MOD to support Defence planning and change management activities. It does this by enabling the capture and presentation of information in a rigorous, coherent and comprehensive way that aids the understanding of comple...
It was through the ongoing and iterative model verification and the testing process during model development, that a realistic model of the actual dynamic interactions was developed and fine-tuned. During this phase of model verification, the weak points of the system were discovered and corrected....
The dynamic compressive behavior of D1 railway wheel steel at high strain rates was investigated using a split Hopkinson pressure bar (SHPB) apparatus. Three types of specimens, which were derived from the different positions (i.e., the rim, web and hub) of a railway wheel, were tested ove...
3d, e). In contrast to the fsRNNs trained by the FORCE learning algorithm, the interference between adjacent intervals was, on average, much larger (~35%) than the average interference (Fig. 3e). This is consistent with the dynamic attractor trying to ‘return’ to its original pattern, ...
This parameter sensitivity indicates that dynamical systems theory is particularly suited for explaining the rich dynamics found in excitable systems. The classification of different bursting mechanisms was pioneered by Rinzel [16], who used a system decomposition into slow and fast subsystems. He ...
‘dropouts’) were systematically different from those who completed the experiment, and hence that our results are biased by the selection method. We first compare the average cooperation rate of the 19 players who dropped out to the main ‘completer’ population. Since players’ behaviour was ...
The principle of “dynamic equivalence” (which was later modified into “functional equivalence”) has a scientific basis as well. It is solidly founded on information theory or communication theory. Nida sees translation as a communication event. Nida holds that in translating, the first thing on...
Goddard is one of four centers built by NASA since its founding on July 29, 1958. It is NASA’s first, and oldest, space center. Its original charter was to perform five major functions on behalf of NASA: technology development and fabrication; planning; scientific research; technical operatio...
The Digital Twin (DT) concept was proposed by Michael Grieves and colleagues from NASA as a vision towards product lifecycle management [4]. Their basic construction comprises a physical system, some kind of dynamic model as its Digital Twin, and a dynamic synchronization mechanism between them, ...
