Kinetic wall : an exploration into dynamic structure
… conjunction; circulatory system, nervous system, structure system and means of motion. For a building to exhibit this kind of sophistication, the integration and design of such active systems must be investigated. With new advances in the engineering of smart materials, computational control …

On the dynamic structure factor for the electron gas
… into a path integral version, then studied its dynamic structure factor S(q,q0 ) systematically. Our study shows that qc defined in RPA not only is the threshold for a bare plasmon, but also in general the one for any number of renormalized plasmons. We have particularly studied large momentum …

High Pressure Nmr Studies of the Dynamic Structure of Liquids
… In these models it is proposed that there are dynamical effects on isomerization because the reaction coordinate is coupled to the surrounding medium. This leads to the dependence of the transmission coefficient upon the collision frequency, which in the absence of electrostatic effects …

Insights Into the Dynamic Structure and Inhibitory Mechanism of Plasminogen Activator Inhibitor Type 1
… the mobile RCL than was evident from the crystal structure of 14-1B. These properties suggested that PAI-1 be grouped in a novel sub-class of serpins exhibiting partially-inserted RCLs and allowed further study of its structure-function relationships in a new light. The accessibility of beta-sheet …

‘Dynamic Structure’ in the Performance of Symphonic Music: An Examination of Wilhelm Furtwängler’s Recordings
… and critical re-evaluations of musical structure have fostered a new understanding of the concept: it has been argued that structure is best understood as a pluralistic and diachronic phenomenon emerging from structural relationships inferred individually by analysts, performers and …

Extending the dielectric formalism in warm dense matter: collisions, dynamic structure factors, and stopping powers
… with sophisticated radiation- or magneto- hydrodynamics (R/MHD) codes. In turn, the accuracy of R/MHD simulations rely on detailed descriptions of the material properties like transport coefficients, stopping powers, scattering and absorption spectra, and many other quantities in the WDM regime. …

Studies of structure and dynamics of biological macro-molecular assemblies by low angle neutron diffraction and inelastic X-ray scattering
… into two parts which focus on the studies of the dynamic structure factor and static inter-particle structure factor respectively. In the first part, we have measured and analyzed the dynamic structure factors of aligned 40 wt% calfthymus Na-DNA molecules with the inelastic X-ray scattering (IXS). …

Mean-field theory for the dynamics of superfluid fermions in the BCS-BEC crossover
We use mean-field theory to investigate the dynamics of superfluid fermions. This thesis includes our two works. The first one is to study Josephson oscillations and self-trapping of superfluid fermions in a double-well potential with time-dependent Bogoliubov-de Gennes equations. We investigate …

Nmr and Polarization Microscopy Studies of Sodium Alkyl Carboxylate Solids and Melts
The dynamic structure of the ionic liquid crystalline mesophase of both sodium n-butyrate and sodium isovalerate is studied using pulsed and Fourier transform NMR. Both the ('1)H self-diffusion measurements and the ('23)Na spin-lattice relaxation time, T(,1), and quadrupole coupling constant,

Deep inelastic scattering by quantum liquids
… and the related concept of the scaling of the dynamic structure function S(k,$\omega$) at large k and $\omega$ have played a dominant role in the analysis of the deep inelastic neutron scattering by quantum liquids. These concepts are reviewed along with the prevalent approximations to treat …

High Pressure Nmr Studies of the Dynamics of Fluids and Fluid Mixtures (Supercritical, Dimethyl-Sulfoxide, Diffusion)
… as an essential variable in studies of the dynamic structure of fluids. The use of pressure allows the determination of the effects of density on the properties of the fluid, independent of thermal effects.

Deep inelastic neutron scattering and single particle kinetic energies in condensed noble gases
… National Laboratory was used to measure the dynamic structure factor at values of the wave-vector transfer between 15 and 30 A$\sp{-1}$. Data have been analyzed with resolution techniques, and the single particle kinetic energies have been determined.

Shared decision-making and control between humans and adaptive control algorithms
… thesis addresses the problem of controlling a dynamical system subject to both parametric uncertainties and abrupt changes in the dynamic structure of the system, by proposing a shared control architecture predicated on a suitable division of responsibilities between supervisory human operators …

Vibration-based finite element model updating and structural damage identification
… on vibration measurements for existing aging structures offers a promising technique for effectively managing the deteriorating structures. The main objectives of this research are to develop a procedure for finite element model updating by using incomplete modal data identified from vibration …

EXTRACT NESSENTIAL FACTORS FROM HIGH DIMENSIONAL BIG DATA
… extracted from data are useful to explain the dynamic structure of data and can provide important information. In this thesis, we proposed three methods aiming to extract fundamental factors from big data. First, we proposed the PIF and SG-ICA to extract factors from high-dimensional data. …

Patches As Agents
… by transforming the static environment into a dynamic structure made of thousands of patch agents. In this new framework, the traditional static terrain is now composed of a collection of independent patch agents, each with its own behaviors and traits. This transformation enables the patch …
