21. A preparatory step may be required, possibly involving microscale simulations constrained to keep the macrostates fixed. 22. Figure 2 is a sample computational microscale algorithm that corresponds to the macroscale model of Figure 1. 23. In the quantum " microscale " world, objects can tunnel almost magically through impenetrable barriers. 24. Microscale strain gauges are widely used in Micro-Opto-Electro-Mechanical Systems ( MOEMS ).25. At any given time there could be 8 or 9 distinct microscale eddies existing at the same time. 26. On the microscale , the stacked tablet layers and the wavy interface between them are two other hierarchical structures. 27. The microscale model does not explicitly incorporate the differential equation, though for large populations it simulates it closely. 28. Microscale Thermophoresis ( MST ) measures the size, charge and hydration entropy of molecules / substrates in real time.29. The Advanced Research WRF ( ARW ) is supported to the community by the NCAR Mesoscale and Microscale Meteorology Division. 30. Higher order schemes for systems where the microscale noise is still apparent on the macroscale time step are more problematic.
