New Concept of Electromagnetic Impact-driven Jet Injector with Enhancement of Jet Power and Control [PDF]
Journal of Applied Fluid MechanicsThis study presents an improved needle-free jet injector driven by an electromagnetic actuator based on the impact-driven method (IDM). The developed IDM-v2 system enhances controllability, compactness, and jet performance compared with the previous gas ...

Impact of dye injection on intracoronary pressure [PDF]
EuroIntervention, 2009 Coronary angiography is widely used to estimate coronary blood flow velocity, as in the TIMI frame count method. However, it is unknown to what extent the injection of dye elevates intracoronary pressure which may accelerate coronary blood flow velocity.

The impact of pulse pressure on the accuracy of wrist blood pressure measurement [PDF]
Journal of Human Hypertension, 2008 There is an increasing number of wrist blood pressure measurement devices that successfully passed the validation procedures of the British Hypertension Society (BHS) and the European Society of Hypertension (ESH). It remains unknown, however, whether pulse pressure as a marker of arterial stiffness and vascular ageing affects the accuracy of these ...

IMPACT PRESSURES PRODUCED BY BREAKING WAVES
Coastal Engineering Proceedings, 1974 Experiments were conducted in a vacuum tank in order to investigate the effect which entrained air has on impact loads which are produced when waves break upon a structure. In these experiments a flat plate was dropped onto a still water surface in an environment where the ambient pressure of the surrounding air could be controlled.

Sources of the Measurement Error of the Impact Pressure in Sloshing Experiments
Journal of Marine Science and Engineering, 2019 Sloshing experiments have increasingly received academic attention. Understanding the measurement errors in the sloshing impact pressures is an important parts of the sloshing experiments since these errors, which arise from experimental conditions ...

Modeling the impact of thoracic pressure on intracranial pressure
npj MicrogravityAbstractA potential contribution to the progression of Spaceflight Associated Neuro-ocular Syndrome is the thoracic-to-spinal dural sac transmural pressure relationship. In this study, we utilize a lumped-parameter computational model of human cerebrospinal fluid (CSF) systems to investigate mechanisms of CSF redistribution.

Field Measurements of Impact Pressures in Surf
Coastal Engineering 1974, 1974 Field measurements were made of the vertical distribution of impact pressures exerted by breaking waves. Four distinct types are recognized and compared. These are near-breaking wave, plunging breaker, spilling breaker and post-breaking bore. The measurements were obtained by placing a 6 foot aluminum flat plate, backed by a cylinder in the surf zone ...

Non-destructive testing based on Unet-CBAM network for pulsed thermography
Frontiers in PhysicsInfrared thermography (IRT) is a non-destructive testing technique that can detect the internal defects of materials. In the detection of austenitic stainless-steel pipes with large curvature, image noise caused by uneven heating is difficult to avoid ...
