Nonlinear Scalespace via Hierarchical Statistical Modeling
Nonlinear scalespace should be based on a hierarchical statistical model of the image intensity function. This model should contain an explicit representation of the multiscale structure of edges and corners. Using this model we can have a non-ad-hoc basis for computing the parameters we need to determine how much smoothing we should do at points that appear to be edge points. We also have a ba...
متن کاملNonlinear modeling of thermoacoustic systems
Thermoacoustic systems convert energy from heat to acoustic power and vice versa. These systems have commercial interest due to the high potential efficiency and low number of moving parts. To numerically predict the performance of a thermoacoustic device inherent nonlinearities in the system, such as thermoacoustic streaming and generation of harmonics need to be taken into account. We present...
متن کاملStatistical Emulator Construction for Nonlinear Smart Systems
Comprehensive physical models can accurately quantify the dynamics of nonlinear and hysteretic systems but often require significant computational cost. This can reduce their effectiveness when performing sensitivity analysis, uncertainty analysis, parameter calibration or system design which typically requires multiple iterations of computationally expensive routines. This can also preclude th...

To my family, for their love and support ii ACKNOWLEDGEMENTS This dissertation is the end result of my stay at the University of Michigan during which I have benefited from contact and varied relationships with many members of its community. I thank my advisor Professor Edward Ionides for his patient advice, generosity with his time and for the encouragement to join the statistics research comm...
متن کاملStatistical energy analysis of nonlinear vibrating systems.
Nonlinearities in practical systems can arise in contacts between components, possibly from friction or impacts. However, it is also known that quadratic and cubic nonlinearity can occur in the stiffness of structural elements undergoing large amplitude vibration, without the need for local contacts. Nonlinearity due purely to large amplitude vibration can then result in significant energy bein...
