Integrating Reinforcement Learning With Explainable Artificial Intelligence for Real‐Time Clinical Decision Support in Dynamic Healthcare Environments

Advanced Intelligent Systems, EarlyView.
A hybrid Reinforcement Learning–Explainable AI framework integrates SHAP and LIME explanations directly into a Deep Q‐Network inference loop for real‐time ICU decision support. Trained on 18 142 mechanically ventilated stays from the eICU database, the system attains 93.0% decision accuracy, 20% fewer errors than RL alone, and a 91% clinician trust ...

Thermally Drawn Bioelectric Catheters: Enabling Proprioceptive Endovascular Navigation

Advanced Intelligent Systems, EarlyView.
This work introduces a novel bioelectric navigation system eliminates the need for harmful fluoroscopy during endovascular surgeries. A bespoke 16‐electrode catheter is fabricated using rapid thermal drawing and laser micro‐machining. Paired with a real‐time tracking algorithm fusing vascular geometry detection and distance estimation, this technology ...

Sediment Transport, Part I: Bed Load Transport

Journal of Hydraulic Engineering, 1984
A method is presented which enables the computation of the bed-load transport as the product of the saltation height, the particle velocity and the bed-load concentration. The equations of motions for a solitary particle are solved numerically to determine the saltation height and particle velocity. Experiments with gravel particles (transported as bed

BED LOAD TRANSPORT IN THE PRESENCE OF WASH LOAD TRANSPORT

ISH Journal of Hydraulic Engineering, 2007
ABSTRACT Experiments were conducted in a 30 m long 0.204 m wide and 0.5 m deep tilting flume to study the effect of different equilibrium concentration of wash load transport on the transport of uniform and nonuniform sediments through an alluvial channel and on the composition of active bed layer.

Bed load transport by bed form migration

Acta Geophysica, 2012
A theoretically-based methodology is presented for the determination of bed load transport from high-resolution measurements of bed surface elevations for steady-state or developing dunes. The methodology is based on the general form of the Exner equation for sediment continuity and requires information on the distribution of sediment volume ...

Formulas for the Transportation of Bed Load

Journal of Hydraulic Engineering, 2017
AbstractThis paper introduces new formulas for the transportation of bed load that disputes Einstein’s use of his time factor, tE, in calculating transport rate.

On transport of bed load by waves

Journal of Hydraulic Research, 1989
The Bagnold's energy concept for sediment transport is used to estimate the volume of sediment mobilized by strong wave action. The results are compared with wave tunnel data for sheet flow conditions and with bed load formulae by Sleath and by Madsen and Grant. The predictions differ excessively and agreement with wave tunnel data is poor. The results

Bed‐Load and Suspended‐Load Transport of Nonuniform Sediments

Journal of Hydraulic Engineering, 1991
Methods are available for the computation of the bed-load and suspended-load transport rates of uniform sediments. However, limited studies exist for nonuniform sediments. These studies, in general, lack simplicity, and often make use of various correction factors to be read from a series of tables and graphs.

Fractionwise calculation of bed load transport

Journal of Hydraulic Research, 1996
Extensive experiments conducted by the writers on fractional bed load transport rates are reported. These data as well as those available from other sources, covering wide range of flow conditions and sediment nonuniformity, have been analysed. Firstly, the semi-theoretical model proposed by Misri et al.

The transportation of bed‐load by streams

Eos, Transactions American Geophysical Union, 1934
The problem of bed‐load movement has been studied by a number of engineers and scientists during the past seventy years and a considerable amount of data has been published. The increasing use of river‐ and harbor‐models has accentuated its importance because of the necessity for selecting a material capable of being moved which will not at the same ...
