We compare the roughness of minimal energy(ME) surfaces and scalar “quasi-static” fracture surfaces(SQF). Two dimensional ME and SQF surfaces have the same roughness scaling, w ∼ L (L is system size) with ζ = 2/3. The 3-d ME and SQF results at strong disorder are consistent with the randombond Ising exponent ζ(d ≥ 3) ≈ 0.21(5 − d) (d is bulk dimension). However 3-d SQF surfaces are rougher than...

Vertical differencing is a very different problem from horizontal differencing. This may seem odd, but the explanation is very simple. There are three primary factors. First, gravitational effects are very powerful, and act only in the vertical. Second, the Earth's atmosphere is very shallow compared to its horizontal extent. Third, the atmosphere has a lower boundary. To construct a vertically...

Ultrasound elastography is a technique used for clinical imaging of tissue stiffness with a conventional ultrasound machine. It was first proposed two decades ago, but active research continues in this area to the present day. Numerous clinical applications have been investigated, mostly related to cancer imaging, and though these have yet to prove conclusive, the technique has seen increasing ...

Machine tool calibration is becoming recognised as an important part of the manufacturing process. The current international standards for machine tool linear axes calibration support the use of quasi-static calibration techniques. These techniques can be time consuming but more importantly a compromise in quality due to the practical restriction on the spatial resolution of target positions on...

The DaVinci Simulator can be used to analyze the stacking process using different forces and different placements of the fingers. An existing code for block-stacking simulates free fall of blocks. However, a free fall cannot be quasi-static. So, a modified code has been written to include additional forces (applied by the robot fingers) which act opposite to the gravitational force to enable qu...

This study investigated the impact of prolonged consonant durations on the McGurk effect and the role of static visual information in this cross-modal illusion. It was found that the McGurk effect did not break down nor diminish in strength when the consonant duration was extended up to 3.8s. This remained unchanged when the video frames in the quasi-static phase of the prolonged target consona...

A new small-signal model for fully depleted silicon-oninsulator (FD-SOI) MOSFETs operating at RF frequencies is presented. The model accounts for the non-quasi-static effect by determining model parameters using a curve fitting procedure to reproduce the frequency response of FD-SOI MOSFETs. The accuracy of the model is validated by comparison of S parameters with measured results in the range ...

There has been a surge of work on models for coupling surface-water with groundwater flows which is at its core the Stokes-Darcy problem. The resulting (Stokes-Darcy) fluid velocity is important because the flow transports contaminants. The analysis of models including the transport of contaminants has, however, focused on a quasi-static Stokes-Darcy model. Herein we consider the fully evolutio...
