RISOn Stability of Time-Varying Multidimensional Linear Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this Technical Brief, a sufficient condition to guarantee the exponential stability for a time-varying system Ẍ + DẊ + K (t)X = 0 is obtained. We mainly made up the condition by ...
A Sufficient Stability Condition for Linear Conservative Gyroscopic Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A sufficient stability condition for linear conservative gyroscopic systems with negative definite stiffness matrices is given. The condition for the stability is stated in terms of the coefficients ...
Mixed Convective Heat Transfer Past a Heated Square Porous Cylinder in a Horizontal Channel With Varying Channel Height
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The laminar mixed convection flow across the porous square cylinder with the heated cylinder bottom at the axis in the channel has been carried out numerically in this paper using a semi-implicit ...
Stabilization of an Axially Moving String by Nonlinear Boundary Feedback
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we consider the system modeled by an axially moving string and a mass-damper-spring (MDS) controller, applied at the right-hand side (RHS) boundary of the string. We are concerned ...
Adaptive Boundary Control of an Axially Moving String System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes an adaptive boundary control to an axially moving string system, which couples with a mass-damper-spring (MDS) controller at its right-hand-side (RHS) boundary. Unknown parameters ...
A Statistical Model of Bubble Coalescence and Its Application to Boiling Heat Flux Prediction—Part II: Experimental Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mechanistic model for the boiling heat flux prediction proposed in Part I of this two-part paper (2009, “A Statistical Model of Bubble Coalescence and Its Application to Boiling Heat Flux ...
A Statistical Model of Bubble Coalescence and Its Application to Boiling Heat Flux Prediction—Part I: Model Development
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work a statistical model is developed by deriving the probability density function (pdf) of bubble coalescence on boiling surface to describe the distribution of vapor bubble radius. ...
Proposed Modification to Whole Domain Function Specification Method to Improve Accuracy of Its Estimations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the inverse heat transfer problem of laminar forced convection within a circular pipe. The performances of two classical algorithms used in the whole domain function ...
Impacts of the Atlantic Multidecadal Oscillation on the Relationship of the Spring Arctic Oscillation and the Following East Asian Summer Monsoon
Publisher: American Meteorological Society
Abstract: Previous studies indicated that spring Arctic Oscillation (AO) can influence the following East Asian summer monsoon (EASM). This study reveals that the Atlantic multidecadal oscillation (AMO) has a pronounced modulation ...
Simulation-Hybrid Approach to Protecting Aging Bridges against Nearby Tunnel Excavation
Publisher: American Society of Civil Engineers
Abstract: Numerous urban infrastructures (e.g., bridges, roads, tunnels, pipes) are aging and vulnerable to external disturbance, particularly for tunneling excavation in densely built areas. A simulation-hybrid approach for ...
