A Theory for Self-Sustained Multicentennial Oscillation of the Atlantic Meridional Overturning Circulation
Publisher: American Meteorological Society
Abstract: In this work, a single-hemisphere 4-box model is used to study the low-frequency variability of the Atlantic meridional overturning circulation (AMOC). We introduce an enhanced mixing mechanism in the subpolar ocean to ...
Influence of Fracture Geometry on the Krauklis Wave in Finite Fractures
Publisher: ASCE
Abstract: Study of the Krauklis wave in fractured media reveals the potential for characterizing fracture geometry. In this paper, a finite element scheme is proposed to simulate the Krauklis wave in fractures with different geometries. ...
Coordination Mechanism of Transportation-inventory Model in Fuzzy Environment
Publisher: American Society of Civil Engineers
Abstract: For the system coordination of transportation-inventory problem in the presence of uncertainty in customer demand, inventory cost, and lead time, this paper, from the point of optimizing logistics cost, establishes the ...
Exponentially Dissipative Control for Singular Impulsive Dynamical Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper studies the problem of exponentially dissipative control for singular impulsive dynamical systems. Some necessary and sufficient conditions for exponential dissipativity of such systems are established in terms ...
Longwall Top Coal Caving Mechanisms in the Fractured Thick Coal Seam
Publisher: ASCE
Abstract: In this study, the finite difference method (FDM) coupled with a discrete fracture network (DFN) was utilized to analyze longwall top coal caving (LTCC) behaviors. The integrated FDM–DFN model enabled the influence of the ...
Computer Vision–Based Counting Model for Dense Steel Pipe on Construction Sites
Publisher: ASCE
Abstract: Building material inventory is routine work of the material delivery process at most construction sites. Manual counting is the conventional manner of taking inventory; however, it is subjective, time consuming, and error ...
An Iterative Neural Operator to Predict the Thermo-Fluid Information in Internal Cooling Channels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design of internal cooling channels played an important role in turbine cooling. Distributions of thermo-fluid information, including surface distributions, cross section distributions, and projected distributions are ...
Comparative Univariate and Regression Survival Analysis of Lane-Changing Duration Characteristic for Heavy Vehicles and Passenger Cars
Publisher: ASCE
Abstract: In contrast to passenger cars, the lane-changing (LC) behavior of heavy vehicles has a more profound impact on traffic flow. This paper investigates LC duration characteristics for heavy vehicles and passenger cars through ...
Resilience Assessment for Streamline Network of Transportation Hub Complex Based on Service Performance
Publisher: American Society of Civil Engineers
Abstract: A resilient transportation hub complex affected by a disturbance can maintain minimum performance and rapidly resume operations, while dealing with growing service demands imposed by the unfolding disturbance management. ...
Novel Hermite Polynomial Model Based on Probability-Weighted Moments for Simulating Non-Gaussian Stochastic Processes
Publisher: ASCE
Abstract: The Hermite polynomial model based on the first-four central moments of non-Gaussian distribution is widely applied to simulate non-Gaussian stochastic processes due to its simplicity and efficiency. Although a variety of ...
