Cramer-Rao bound analysis of multi-frame blind deconvolution
… thesis explores how support constraints and multiple frames affect multi-frame blind deconvolution. Previous research in non-blind deconvolution, which seeks to estimate an object from a blurred and noisy image, characterized how the use of support constraints exploited spatial noise …

Seismic Vulnerability Assessment of As-Built and Retrofitted Multi-Frame Box-Girder Bridges
… forces. These bridge types are categorized as multi-frame bridges because in-span hinges divide the structure into separate frames. There is a significant amount of evidence to suggest that adjacent frames often vibrate out of phase during strong earthquakes. Therefore, two different types of …

A Performance Comparison of Frame Structures in WiMAX Multi-Hop Relay Networks
Wireless multi-hop relay systems are the newest amendment to the IEEE 802.16 standard for local and metropolitan area networks, else known as WiMAX. Relay systems come in different flavours, based on their capabilities and have the potential to offer many advantages over the single-hop technology. …

Physical Therapists’ Perceptions Of Leadership Orientations: An Exploratory Case Study
… To what degree do physical therapists exhibit multi-frame leadership as defined by Bolman and Deal? To what degree do physical therapists use each of the four frames as defined by Bolman and Deal, Structural, Human Resources, Political and Symbolic? What leadership frames as defined by Bolman …

Estimation of nonlinear mechanical properties of atherosclerotic plaques
… in a nonlinear constitutive model. A new multi-frame scheme is introduced to better perform the estimation on a nonlinear mechanical model and reduce the effects of noise. Results show while it is feasible to estimate the nonlinear mechanical properties of plaque, the accuracy can depend …

Rayleigh—Taylor-Instability Evolution in Colliding-Plasma-Jet Experiments with Magnetic and Viscous Stabilization
… plasma jet and a stagnated, magnetized plasma. A multi-frame fast camera captures Rayleigh—Taylor-instability growth while interferometry, spectroscopy, photodiode, and magnetic probe diagnostics are employed to estimate plasma parameters in the vicinity of the collision. As the instability grows, …

Frames In Hilbert C*-modules
Since the discovery in the early 1950's, frames have emerged as an important tool in signal processing, image processing, data compression and sampling theory etc. Today, powerful tools from operator theory and Banach space theory are being introduced to the study of frames producing deep results …

Leadership Orientation Frame Preferences Of School Boards In Mississippi
… work through the four organizational lenses or frames developed by Dr. Terrence Deal and Dr. Lee Bolman (2013). Using the four frame model (structural, human resource, political, and symbolic), this study examined the self - perceived leadership orientations of school board members from …

The policy-formulation process in higher education as an aspect of organizational change.
… to calls for reform. Studies incorporating multiple perspectives, various systems levels, and a variety of theoretical frames are even more limited and yet organizations can best be understood when consideration is given to the complex interacting forces that go to make up the systems. This …

Stochastic prediction in sequential high-dimensional observation space
… are the first to provide an effective stochastic multi-frame prediction for real-world videos. We demonstrate the capability of these methods in predicting detailed future frames of videos on multiple real-world datasets, both action-free and action-conditioned. We also illustrate how such methods …

Deep learning in sequential data analysis
… and sophisticated image-based deep learning frameworks without building from scratch? In this dissertation we develop techniques and methods that enable us to incorporate sequential information into existing image-based deep learning frameworks for different computer vision tasks. More …

The Science of Team Science: Exploring Principal Investigator Leadership Style and Team Collaboration Satisfaction
… members identified that the PIs used all of the frames, but were more likely to use the human resource and structural frames. The pattern of frame use resulted in the identification that PIs were more likely to adopt a multi-frame leadership style rather than the no, single, or paired styles. …

Frame Analysis of the Self-Perceived Leadership Orientations of Headmasters of the Independent Schools Association of the Southwest, Southern Association of Independent Schools, and the Association of Independent Schools of Greater Washington Member Schools
… of work that supports Bolman and Deal's (2003) multi-frame explanation that leaders use different orientations (frames) to understand their roles, clarify organizational situations, and make decisions. Using the four-frame model (structural, human resource, political, and symbolic) by Bolman and …

RECONSTRUCTION MODELS TO IMPROVE IMAGE QUALITY
… speed and collect a large number of low-quality frames; similarly, some surveillance cameras have low acquisition speed and collect low quality images, due to the storage space restrictions or limited network bandwidth to transfer the data. It is hard to perform satisfactory image processing on …

Optimal Image-Aided Inertial Navigation
… The development of a tightly-coupled stereo multi-frame aided inertial navigation algorithm for reducing position and orientation drifts. Usually, the image aiding based on the visual odometry uses the tracked features only from a pair of the consecutive image frames. The proposed method …

Real-time observations of materials under dynamic loading conditions at the micron scale
… surfaces were monitored using an ultrafast multi-frame camera. In particular, the impact response of poly(urethane urea) (PUU) elastomers was investigated in order to further the understanding of the molecular influence on the dynamical behavior of PUUs. The results will provide an impetus …
