Oscillatory oseenlets
… However, the time-harmonicterms given by the oscillatory oseenlets are not. In particular, the Green's functions associatedwith these terms are presented.In this thesis, the oscillatory oseenlet solution is presented for the velocity and pressure,and the forces generated by them are …

Pattern formation in oscillatory systems
… second topic, we start with an introduction for oscillatory clusters in the Belousov-Zhabotinsky reaction. The main idea of this topic is to find the phase property of oscillators in the Oregonator and FHN type models with global inhibitory feedback. Numerical simulations suggest that, in many …

Oscillatory Flow Driven by Cavity
<p>Flows past a cavity are known to exhibit an oscillatory behavior with an amplitude and frequency dependent on the incoming flow properties and the geometry of the cavity. Experiments and numerical analyses have been performed to determine the effects of a flow passing through an axisymmetric …

Antisolvent crystallisation in oscillatory baffled platforms
… produce crystal products with unique properties.;Oscillatory baffled crystallisers (OBCs) are platforms that generate intense mixing by the oscillatory motion of fluid through periodic constrictions, referred to as baffles. The oscillatory motion generates eddy currents through these baffles and …

Complex Patterns in Extended Oscillatory Systems
Ausgedehnte dissipative Systeme können fernab vom thermodynamischen Gleichgewicht instabil gegenüber Oszillationen bzw. Wellen oder raumzeitlichem Chaos werden. Die komplexe Ginzburg-Landau Gleichung (CGLE) stellt ein universelles Modell zur Beschreibung dieser raumzeitlichen Strukturen dar. Diese …

Feedback control of complex oscillatory systems
In the present dissertation paper an approach which ensures an efficient control of such diverse systems as noisy or chaotic oscillators and neural ensembles is developed. This approach is implemented by a simple linear feedback loop. The dissertation paper consists of two main parts. One part of …

Scale-up of oscillatory flow mixing
Oscillatory Flow Mixing is a recent development in mixing technology which has evolved over the past decade. It has a number of similarities to other mixing technologies, particularly pulsed and reciprocating plate columns, but at the laboratory scale has demonstrated a number of advantageous …

Estimates on Oscillatory Singular Integral Operators
<p>Included with every oscillatory singular integral operator is a phase function and a kernel, both essential to the operator’s behavior over any function space. Studies on such operators are rooted in the deep theories developed by Fourier, Calder´on, Zygmund, and Stein. In this work we show …

Oscillatory Flow Mechanism for Enhanced Heat Transfer
<p>This research project is about the use of an oscillatory flow mechanism to enhance heat transfer. The idea behind this is to induce oscillation of the end wall of one of two connected chambers of a heat exchanger which effectively will induce oscillation of the boundary layer within the …

Characterization of Oscillatory Lift in MFC Airfoils
… characterize the response of an airfoil with an oscillatory morphing, Macro-fiber composite (MFC) trailing edge. Correlation of the airfoil lift with the oscillatory input is presented. Modal analysis of the test airfoil and apparatus is used to determine the frequency response function. The …

Controllable, non-oscillatory damping for deformable objects
… of interest to animation, since it produces non-oscillatory behaviour. This is similar to critical damping, except that it affects all modes independently. The new method is based on the minimization of a slightly modified version of total energy. This framework can be used to simulate many other …

Dynamic modeling and analysis of oscillatory bioreactors
Dynamic modeling of bioreactors is a challenging problem. The complexity of first principle models also make model validation and analysis very difficult and model-based controller design practically intractable. This thesis has focused on finding an effective tool for model dynamic analysis, …

Sharp estimates for trilinear oscillatory integral forms
… introduce some background of the trilinear oscillatory integrals and the motivations for their study. We also outline some key ideas in their proofs, as well as the major novelty of this dissertation. Chapter 2 serves as analytic preparation for the proof of our main theorem. We first extend …

Flotation in a novel oscillatory baffled column
This thesis presents an evaluation of an Oscillatory Baffled Column as a novel flotation device and as a research tool for investigating the role which hydrodynamics play in promoting particle-bubble contacting. The cell differs from a conventional cell design in that bubble generation is decoupled …
