Analysis of Upper Airway Morphology Using Four‐Dimensional Dynamic MRI With Active Deep Learning‐Based Automatic Segmentation

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Upper‐airway morphology changes during breathing can be captured with cine 4D MRI. Active‐learning nnU‐Net reduces manual labeling while maintaining accuracy. Purpose For automatic upper airway segmentation on free‐breathing cine 4D MRI using active learning and quantifying dynamic changes under two mouth positions.

The Weak Core, Partition‐Based Universal Stability, and Their Risk Associations Through A Partial Order

Naval Research Logistics (NRL), EarlyView.
ABSTRACT We are concerned with the stability of a transferable‐utility cooperative (TU) game. First, the concept of core can be weakened so that the blocking of changes is limited to only those with multilateral backings. This principle of consensual blocking, as well as the traditional core‐defining one of unilateral blocking and one straddling in ...

Estimation of cavitation limits from local head loss coefficient [PDF]

, 2008
Cavitation effects in valves and other sudden transitions in water distribution systems are studied as their better understanding and quantification is needed for design and analysis purposes and for predicting and controlling their operation.

Experimental study on the impact of traffic‐induced vibrations on early‐age concrete

Structural Concrete, EarlyView.
Abstract The COUNT (Concreting under Traffic) research project systematically examined the effects of traffic‐induced vibrations on early‐age, hardening concrete—a critical issue for bridge construction and renovation. Traffic closures are often imposed during such projects to mitigate potential damage from vibrations.

Toward Explainable Engineering Decisions: Pursuing a Descriptive Decision Theory at the Intersection of Analysis, Judgment, and Conviction

Systems Engineering, EarlyView.
ABSTRACT Engineers design the technical systems that define and sustain our society. The decision‐making scenarios they face require both quantitative analyses and the consideration of qualitative factors, which are shaped by deeply held beliefs, values, and societal contexts. However, existing engineering decision‐making models, primarily derived from

Higher-order isogeometric thermal vibration analysis of functionally graded porous microplates interacting with an ideal fluid

Case Studies in Thermal Engineering
Underwater plate structures are widely employed in various marine systems and may be subjected to prolonged exposure to high-temperature in environments such as deep-sea hydrothermal fields, oil and gas extraction, and heat exchange, which can ...

Pressure: The Bernoulli Principle and Flow Energy Conservation [PDF]

, 2022
AbstractThe relation between descriptive variables of flowing air, pressure and the like, and the dynamic field, speeds or velocities, are often invoked for their understanding. Such relationships depend on whether the flow is compressible or not. When it is, physical work done by air elements on one another, become important.

Graph neural network‐based attack prediction for communication‐based train control systems

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract The Advanced Persistent Threats (APTs) have emerged as one of the key security challenges to industrial control systems. APTs are complex multi‐step attacks, and they are naturally diverse and complex. Therefore, it is important to comprehend the behaviour of APT attackers and anticipate the upcoming attack actions.
