RISImperfect Information Bargaining Model for Determining Concession Period of PPPs under Revenue Uncertainty
Publisher: ASCE
Abstract: The concession period is a critical contractual parameters for public-private partnership (PPP) projects whose value can significantly influence the financial interests of project participants. However, it has become a ...
Experimental Study on the Dynamic Characteristics and Surface Arc Plasma Control of Shock Train in the Supersonic Inlet
Publisher: ASCE
Abstract: The oscillation characteristics and morphological changes of the shock train in the inlet expansion section and the control of the shock train by surface arc plasma were studied in Mach 2 supersonic flow. A wedge installed ...
Finite Linear Representation of Nonlinear Structural Dynamics Using Phase Space Embedding Coordinate
Publisher: ASCE
Abstract: Modeling of structural nonlinear dynamic behavior is a central challenge in civil and mechanical engineering communities. The phase space embedding of response time series has been demonstrated to be an efficient coordinate ...
Effects of Inlet Preswirl and Cell Diameter and Depth on Honeycomb Seal Characteristics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three-dimensional Reynolds-averaged Navier–Stokes solutions are employed to investigate the discharge and total temperature increase characteristics of the stepped labyrinth seal with honeycomb land. ...
Dynamic Stiffness Analysis of a Beam Based on Trigonometric Shear Deformation Theory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamic stiffness matrix of a uniform isotropic beam element based on trigonometric shear deformation theory is developed in this paper. The theoretical expressions for the dynamic stiffness ...
