Pre‐ and Post‐Interventional Hemodynamic Characterization of the Femoropopliteal Artery Using Vector Flow Imaging in Peripheral Arterial Occlusive Disease

Journal of Ultrasound in Medicine, EarlyView.
Objectives The femoropopliteal (FP) artery is the most frequently revascularized segment in peripheral artery disease (PAD), followed by the iliac segment. Wall shear stress (WSS) is a key local factor implicated in both atherosclerotic plaque formation and restenosis after angioplasty.

Seabed classification in the Gulf of Alaska from acoustic surveys using deep learning

Limnology and Oceanography: Methods, EarlyView.
Abstract High‐resolution mapping of seafloor habitats has wide applications for fisheries, conservation efforts, offshore infrastructure planning, mineral extraction, and scientific modeling. This study leverages existing widespread single‐beam acoustic data and machine learning to create habitat maps for the Gulf of Alaska at a spatial resolution of ...

The misalignment angle in vessel-mounted ADCP

Oceanologia, 2000
A description of the misalignment angle and the consequences if it occurs is given. It is shown that because of gyrocompass errors, the misalignment angle error a has to be computed for each cruise.

Design of Acoustic Doppler Current Profiler Calibration System

IOP Conference Series: Materials Science and Engineering, 2019
Abstract In order to trace and transmit the velocity value of acoustic Doppler current profiler (ADCP), an ADCP velocity measurement method based on deep water channel and unmanned ship is proposed. An unmanned ship carrying ADCP moves at a uniform speed along the planned route.

Observations of the Vertical Structure of Tidal Currents in Two Inlets [PDF]

, 2013
Observations of the vertical structure of broad band tidal currents were obtained at two energetic inlets. Each experiment took place over a 4 week period, the first at Hampton Inlet in southeastern New Hampshire, USA, in the Fall of 2011, and the second

Optical Coherence Tomography for High‐Precision Industrial Inspection in Industry 4.0: Advances, Challenges, and Future Trends

Laser &Photonics Reviews, EarlyView.
This review examines how optical coherence tomography transforms industrial inspection by delivering real‐time, micrometer‐resolution, depth‐resolved imaging. It surveys applications across display manufacturing, thin films, microelectronics, laser processing, and coatings, evaluates performance against conventional techniques, and highlights emerging ...

The effect of migrating dune forms on the flow field of an alluvial river [PDF]

, 2010
The bed of an alluvial river is highly susceptible to changes during the course of its existence. Besides variations of the large scale topography and plan form of the river, smaller scale dune forms can be observed. These recurring dune forms migrate on

Enabling Under Ice Glider Operations: A Backseat Driver Approach

Journal of Field Robotics, EarlyView.
ABSTRACT Polar Oceans are key locations for forcing global ocean circulation, influencing both global climate and biogeochemical cycles. Due to restricted access to these seasonally and perennially ice‐covered regions, these areas are severely undersampled.
