RISOn the Vibration of a Point-Supported Linear Distributed System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The vibration of a constrained dynamical system, consisting of an Euler-Bernoulli beam with homogeneous boundary conditions, supported in its interior by arbitrarily located pin supports and ...
Leadership and Organizational Vision in Managing a Multiethnic and Multicultural Project Team
Publisher: American Society of Civil Engineers
Abstract: To meet the demands of managing complex projects, project leaders face challenges of daily leadership behavior and organizational vision to manage a project team. The challenges are compounded when the task of creating a ...
Sustained High Frequency Dynamic Instability of a Nonlinear System of Coupled Oscillators Forced by Single or Repeated Impulses: Theoretical and Experimental Results
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This report describes the impulsive dynamics of a system of two coupled oscillators with essential (nonlinearizable) stiffness nonlinearity. The system considered consists of a grounded weakly damped linear oscillator ...
Isolated Resonance Captures and Resonance Capture Cascades Leading to Single- or Multi-Mode Passive Energy Pumping in Damped Coupled Oscillators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We examine passive energy pumping in a system of damped coupled oscillators. This is a one-way, passive and irreversible energy flow from a linear main system to a nonlinear attachment that ...
Sea Surface Temperature Warming Patterns and Future Vegetation Change
Publisher: American Meteorological Society
Abstract: ecent modeling studies of future vegetation change suggest the potential for large-scale forest die-off in the tropics. Taken together with observational evidence of increasing tree mortality in numerous ecosystem types, ...
Projected Future Changes in Vegetation in Western North America in the Twenty-First Century
Publisher: American Meteorological Society
Abstract: apid and broad-scale forest mortality associated with recent droughts, rising temperature, and insect outbreaks has been observed over western North America (NA). Climate models project additional future warming and ...
Realization of a Strongly Nonlinear Vibration-Mitigation Device Using Elastomeric Bumpers
Publisher: American Society of Civil Engineers
Abstract: Recent research has shown the viability of using nonlinear energy-sink (NES) devices for vibration mitigation in mechanical and structural systems. When attached to a primary structure, these lightweight passive devices ...

Experimental Testing and Numerical Simulation of a Six-Story Structure Incorporating Two-Degree-of-Freedom Nonlinear Energy Sink
Publisher: American Society of Civil Engineers
Abstract: The nonlinear energy sink (NES) is a fully passive attachment used to rapidly dissipate a significant portion of energy induced in a linear primary structure to which it is attached. In this study, the performance of a ...
