RISLinear Waves in Midlatitudes on the Rotating Spherical Earth
Publisher: American Meteorological Society
Abstract: The linear waves of the shallow water equations in a zonal channel in midlatitudes on the rotating spherical earth are investigated analytically and numerically by solving several relevant eigenvalue problems. For baroclinic ...
The Role of Forcing and Eddy Viscosity Variation on the Log-Layer Mismatch Observed in Wall-Modeled Large-Eddy Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We investigate the role of eddy viscosity variation and the effect of zonal enforcement of the mass flow rate on the log-layer mismatch problem observed in turbulent channel flows. An analysis of the mean momentum balance ...

Heterogeneous Nonlinear Systems Synchronization Based on Adaptive Super Twisting
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, the synchronization of a group of heterogeneous uncertain nonlinear systems is addressed. A strategy based on adaptive super twisting algorithm is proposed, in order to synchronize the outputs of the heterogeneous ...
Decentralized Formation Control Based on Adaptive Super Twisting
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a decentralized formation control based on adaptive super-twisting algorithm (ASTA) is designed for a group of unicycle mobile robots. According to this approach, movements of robots are driven through a ...
Discrete Element Method Study on Effect of Shear-Induced Anisotropy on Thermal Conductivity of Granular Soils
Publisher: American Society of Civil Engineers
Abstract: In this study, a simple idealization of heat transfer by conduction at the interparticle contacts is utilized for the evaluation of thermal conductivity of granular soils when subjected to external loading conditions. ...
Conceptual Modeling Framework to Integrate Resilient and Interdependent Infrastructure in Extreme Weather
Publisher: American Society of Civil Engineers
Abstract: This paper addresses two areas of inquiry: (1) critical infrastructure resilience as recovery and (2) infrastructure interdependencies and dependencies, and both of these areas are evaluated in the context of ...
Longshore Sand Transport Southeast of Bahia de Todos Santos, B. C. Mexico
Publisher: American Society of Civil Engineers
Abstract: We present an analysis of wave directional data from a site in southeast of Bahia de Todos Santos, Baja California, México, spanning a period from March to October 1988. The longshore sand transport is estimated according ...
High-Speed, Noncontact Digital Imaging System for Inspection of Hot-Mix Asphalt Pavements
Publisher: American Society of Civil Engineers
Abstract: This paper discusses the results of the field experimentation of a new system developed to help inspect the construction of asphalt pavements using digital video images. The system computes the gray-level co-occurrence ...
An Immersed Boundary Geometric Preprocessor for Arbitrarily Complex Terrain and Geometry
Publisher: American Meteorological Society
Abstract: here is a growing interest to apply the immersed boundary method to compute wind fields over arbitrarily complex terrain. The computer implementation of an immersed boundary module into an existing flow solver can be ...
