Characterizations of Spatio-temporal Complex Systems
ACKNOWLEDGEMENTS A number of people have guided and participated in the efforts that has resulted in this thesis. As an advisor, Mike has been an inexhaustible source of optimism, no matter how far the experiments might seem from the desired results. Much of the experimental development on laser actuation would not have progressed as long without his direction. Mike has been very patient in dev...
متن کاملEmergence of Complex Spatio-Temporal Behavior in Nonlinear Field Theories
We investigate the emergence of time-dependent nonperturbative configurations during the evolution of nonlinear scalar field models with symmetric and asymmetric double-well potentials. Complex spatio-temporal behavior emerges as the system seeks to establish equipartition after a fast quench. We show that fast quenches may dramatically modify the decay rate of metastable states in first order ...

متن کاملthe study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media
امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Nonlinear Dynamics of the Voice: Bifurcations and Mode Analysis of Complex Spatio-Temporal Signals
In this thesis, the physics of phonation was discussed using the theory of nonlinear dynamics. Digital high speed recordings of human and nonhuman laryneal oscillations, image processing, signal analysis, and modal analysis have been used to quantitatively describe nonlinear phenomena in pathological human phonation, healthy voices in singing, and nonhuman mammalian larynges with vocal membrane...
