Cramer-Rao Bound Analysis Of Multi-Frame Blind Deconvolution, Alim Haji

Optical Science and Engineering ETDs

This 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 correlations to reduce noise in the estimate of the object. In multi-frame blind deconvolution, the blurring function is unknown and must be estimated along with the object. Applying a support constraint to both the object and the blurring functions, when using blind deconvolution, is one way to ensure a unique solution. The effects on the estimate of the object as …

Self-Assembly Of Nanoparticles At Interfaces, Alexander Böker, Jinbo He, Thomas P. Russell, Todd S. Emrick

Todd S. Emrick

Developments in the assembly of nanoparticles at liquid–liquid interfaces are reviewed where the assemblies can be controlled by tuning the size of the nanoparticles and the chemical characteristics of the ligands. Both synthetic and biological nanoparticles are discussed. By controlling the type of ligands, uniform and Janus-type nanoparticles can be produced where, at liquid–liquid interfaces, subsequent reactions of the ligands can be used to generate crosslinked sheets of nanoparticles at the interface that have applications including novel encapsulants, filtration devices with well-defined porosities, and controlled release materials. By controlling the size and volume fraction of the nanoparticles and the chemical …

The Concept Of Resources In Triz, Umakant Mishra

Umakant Mishra

An ideal system should have all advantages and no harms. If the resources consumed are expensive than the output produced then the invented system becomes ridiculous. The objective should be to use least amount of resources, cheapest resources, easily available resources and resources available within the system.

Every system intends to achieve a main useful function. The use of resources should target to improve its main useful function. If certain parts of a system or certain resources lead to unwanted functions or harmful effects then that part of the system needs to be modified and those resources need to be …

The Synthesis And Characterization Of A Novel Polysaccharide Hydrogel For Biomedical Applications Including The Treatment Of Malignant Tumors And The Prevention Of Metastatic Disease, Elizabeth Diana Barker

Masters Theses

Amygel® is an injectable biodegradable controlled release drug delivery system with adjustable release kinetics determined by varying the concentrations of the polymeric components of the material. Amygel® is a starch based biodegradable hydrogel consisting of an interpenetrating network of physically entangled amylose and amylopectin polymer chains crosslinked with d-glucaric acid. Amylose and amylopectin are the two components of naturally occurring starch. The immiscibility of the amylose and amylopectin due to differences in solubility parameter and chain size induces phase separation within the network but because the chains entangled during hydrolysis an interpenetrating network is formed. The chemically reactive carboxyl groups …

Derivation And Application Of A Conserved Orbital Energy For The Inverted Pendulum Bipedal Walking Model, Jerry E. Pratt, Sergey V. Drakunov

Publications

We present an analysis of a point mass, point foot, planar inverted pendulum model for bipedal walking. Using this model, we derive expressions for a conserved quantity, the “Orbital Energy”, given a smooth Center of Mass trajectory. Given a closed form Center of Mass Trajectory, the equation for the Orbital Energy is a closed form expression except for an integral term, which we show to be the first moment of area under the Center of Mass path. Hence, given a Center of Mass trajectory, it is straightforward and computationally simple to compute phase portraits for the system. In fact, for …

Resynthesis Methods For Sound Source Separation Using Shifted Non-Negative Factorisation Models, Derry Fitzgerald, Matt Cranitch

Conference papers

Recently, techniques such as shifted 2D non-negative matrix factorisation and shifted 2D non-negative tensor factorisations have been proposed as methods for separating harmonic musical instruments from single and multi-channel mixtures. However, these methods require the use of a Constant Q transform, for which no true inverse exists. This has adverse effects on the quality of the resynthesis of the separated sources. In this paper, a number of different resynthesis methods are investigated in order to determine the best approach to resynthesis

Recruitment And Retention: The Role Of The Public Image Of Engineering, Eddie Conlon

Conference papers

This paper presents findings of three surveys conducted with first year students in the Faculty of Engineering in the Dublin Institute of Technology. It focuses on their motivation for studying engineering and the people who influenced the decision to do engineering. It shows there are gaps in the students’ knowledge of their programmes and also between their expectations and their experience of their course. Some proposed areas of action are identified to increase both recruitment and retention. It is argued that projecting an image of engineering as a creative activity would help in addressing recruitment and retention issues.
