RISPhysics of the Microchannel Flow Boiling Process and Comparison With the Existing Theories
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, six benchmark experiments are conducted on bubbles at different growth stages to evaluate the assumptions of the existing microchannel flow boiling heat transfer models/hypothesis. The results show that the ...
Development of a Green High-Performance Fiber-Reinforced Cementitious Composite Using Local Ingredients
Publisher: ASCE
Abstract: Recent materials developed and applied for repairing, strengthening, and refining the performance of various structural elements are high-performance fiber-reinforced cement composites (HPFRCCs). These materials exhibit ...
System Dynamics Modeling of Reservoir Operations for Flood Management
Publisher: American Society of Civil Engineers
Abstract: There exists a strong need to explore simulation techniques that not only represent complex dynamic systems in a realistic way but also allow the involvement of end users in model development to increase their confidence ...
Spatial System Dynamics: New Approach for Simulation of Water Resources Systems
Publisher: American Society of Civil Engineers
Abstract: A new approach called spatial system dynamics (SSD) is presented to model feedback based dynamic processes in time and space. This approach is grounded in control theory for distributed parameter systems. System dynamics ...
Assessing Hydrologic Impact of Climate Change with Uncertainty Estimates: Bayesian Neural Network Approach
Publisher: American Meteorological Society
Abstract: A major challenge in assessing the hydrologic effect of climate change remains the estimation of uncertainties associated with different sources, such as the global climate models, emission scenarios, downscaling methods, ...
Application of Support Vector Machine in Lake Water Level Prediction
Publisher: American Society of Civil Engineers
Abstract: This paper examines the potential of the support vector machine (SVM) in long-term prediction of lake water levels. Lake Erie mean monthly water levels from 1918 to 2001 are used to predict future water levels up to
Evaluating Urban Storm-Water Infrastructure Design in Response to Projected Climate Change
Publisher: American Society of Civil Engineers
Abstract: One of the goals of storm-water infrastructure design is to mitigate effects resulting from extreme hydrologic events. Projected changes in climate are expected to lead to an increase in the frequency and magnitude of ...
Nonlinear Robust Roll Autopilot Design Using Sum-of-Squares Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we study nonlinear robust stabilization of roll channel of a pursuit using the sum of squares (SOS) technique. Roll control is a fundamental part of flight control for every pursuit. A nonlinear state feedback ...
Numerical Investigation of the Transient Hydrothermal Behavior of a Ferrofluid Flowing Through a Helical Duct in the Presence of Nonuniform Magnetic Field
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates numerically the time dependent hydrothermal behavior of a ferrofluid (water and 4 vol. % Fe3O4) flowing in a helical channel, which is exposed to a nonuniform transverse magnetic field and its walls ...
Crushed Limestone Aggregate Strength Influenced by Gradation, Fines Content, and Dust Ratio
Publisher: American Society of Civil Engineers
Abstract: Quality classes of aggregate materials used in unbound base and subbase construction are quite important for the longevity of highway pavements. Aggregate gradation, fines content, Atterberg limits, and dust ratio all ...
