Non-destructive measurement of acceleration-induced displacement fields within a closed object is a fundamental challenge. Inferences of how the brain deforms following skull impact have thus relied largely on indirect estimates and course-resolution cadaver studies. We developed a magnetic resonance technique to quantitatively identify the modes of displacement of an accelerating soft object r...

Xausa, Beghi, and Zanforlin (J. Math. Psychol. 45(4) (2001) 635) provide an account of perceptual organization based on their ‘minimal relative motion’ principle. They claim that this principle can account for the percept generated by a contracting bar that is simultaneously translating laterally. We critique the mathematical analysis provided in the aforementioned paper. We conclude that the ‘...

In practice, concrete compression strength is used to compute the elastic modulus of concrete. For this calculation, various formulations are given in different codes. For a given concrete compressive strength, elastic modulus values calculated using different equations given in the codes could vary. In the present study, upper and lower boundaries of elasticity modulus are calculated using fuz...

Visualization experiments of the unsteady immiscible displacement of a fluid by another are performed on glass-etched pore networks of well-controlled morphology by varying the fluid system and flow conditions. The measured transient responses of the fluid saturation and pressure drop across the porous medium are introduced into numerical solvers of the macroscopic two-phase flow equations to e...

A quantitative understanding of three-phase flow in porous media is required to address many diverse processes in the subsurface, e.g., improved oil recovery, CO2 sequestration, and aquifer clean-up. In turn, all predictive models of three-phase flow originate from interpretations of onedimensional laboratory experiments; when these interpretations are flawed, so are the models. In this paper w...

INTRODUCTION Intra-abdominal hemorrhage following pancreatic fistula is a fatal complication after pancreatico-duodenectomy. Intra-abdominal hemorrhage has reportedly decreased with the use of fibrin glue or polyglycolic acid felt and wrapping of the skeletonized vessels by omentum or falciform ligament. However, there are no extremely effective methods for the prevention of hemorrhage. Here, w...

This study presents a steel container crane movement analysis and assessment based on structural health monitoring (SHM). The accelerometers are used to monitor the dynamic crane behavior and a 3-D finite element model (FEM) was designed to express the static displacement of the crane under the different load cases. The multi-input single-output nonlinear autoregressive neural network with exte...
