A Ten-Year Record Of Supraglacial Lake Evolution And Rapid Drainage In West Greenland Using An Automated Processing Algorithm For Multispectral Imagery, B. F. Morriss, R. L. Hawley, J. W. Chipman, L. C. Andrews Dec 2013

A Ten-Year Record Of Supraglacial Lake Evolution And Rapid Drainage In West Greenland Using An Automated Processing Algorithm For Multispectral Imagery, B. F. Morriss, R. L. Hawley, J. W. Chipman, L. C. Andrews

Dartmouth Scholarship

The rapid drainage of supraglacial lakes introduces large pulses of meltwater to the subglacial environment and creates moulins, surface-to-bed conduits for future melt. Introduction of water to the subglacial system has been shown to affect ice flow, and modeling suggests that variability in water supply and delivery to the subsurface play an important role in the development of the subglacial hydrologic system and its ability to enhance or mitigate ice flow. We developed a fully automated method for tracking meltwater and rapid drainages in large (> 0.125 km2) perennial lakes and applied it to a 10 yr time …

A Polydisciplinary Journey: From Coffee To Prototype, Carmen Trudell Oct 2013

A Polydisciplinary Journey: From Coffee To Prototype, Carmen Trudell

Learn X Design Conference Series

Several literatures acknowledge that design education has been shifting from the mere training of young students to be skilled professionals to a more profound understanding of the social context in which the future designs will emerge (Norman, 2010) (Findeli, 2001)(Frascara, 2007). This comes from the increased understanding that in order to craft sustainable and viable products, being material or virtual, students have to refer in the first place to their living environment and feed their creativity with the challenges experienced in real life. For educators this starts firstly an investigation on how to guide their students in the exploration of …

Merging Creative Design And Cad Learning Activities In A Product Design Programme, Pearl O'Rourke, Colm O'Kane, Leslie Smith, Michael Ring Sep 2013

Merging Creative Design And Cad Learning Activities In A Product Design Programme, Pearl O'Rourke, Colm O'Kane, Leslie Smith, Michael Ring

Conference Papers

Traditional learning and teaching methods for creativity differ from those used in a scientific context. Although the creative process can benefit from a certain level of prescription and structural constraint - with time allocated to research, problem definition, conceptualisation and idea development - flexibility and fluidity are necessary for creative innovation. In contrast, the more linear and rigid pedagogies associated with science and engineering education facilitate efficient learning of subjects such as those based on software packages, manufacturing and materials theory or mechanics. This paper describes the development of a project which aims to establish constructive links between the learning …

Connecting For Impact: Multidisciplinary Approaches To Innovation In Small To Medium Sized Enterprises (Smes), Marc Bailey, Neil Smith, Mersha Aftab May 2013

Connecting For Impact: Multidisciplinary Approaches To Innovation In Small To Medium Sized Enterprises (Smes), Marc Bailey, Neil Smith, Mersha Aftab

Learn X Design Conference Series

This paper reveals the methodology developed and adopted by groups of Multidisciplinary Design Innovation Masters students whilst working on projects with regional Small to Medium Sized Enterprises (SME’s). It exposes an eight-stage approach and shows how the creation of a ‘problem-space tapestry’ acts as a mediator between different disciplinary approaches. The authors used a combinationof observation, interview, post project-analysis and auto ethnographic reflection in order to uncover this process and to draw conclusions about the conditions that are necessary to support university based multidisciplinary design-led innovation projects of this type.


The 'Emancipated Ladies' Of America In The Travel Writing Of Fredrika Bremer And Alexandra Gripenberg, Sirpa Salenius Feb 2013

The 'Emancipated Ladies' Of America In The Travel Writing Of Fredrika Bremer And Alexandra Gripenberg, Sirpa Salenius

Journal of International Women's Studies

The Swedish novelist Fredrika Bremer (1801-1865) and the Finnish Baroness Alexandra Gripenberg (1857-1913), both active women’s rights advocates who toured in the United States in the 1850s and 1880s, respectively, used their travel writing as a powerful medium in promoting their ideological agendas. They articulated their gender politics through presenting American women as pioneers, leaders in women’s suffrage and models of female emancipation. Women’s activism in America was perceptible not only in the formally organized women’s rights movement but also in various reform movements (abolitionism, temperance, and labor movements) that contributed to women’s suffrage on a worldwide scale. As the …

Improving Chronic Kidney Disease Care With Group Visits, Vicki Montoya Jan 2013

Improving Chronic Kidney Disease Care With Group Visits, Vicki Montoya

Electronic Theses and Dissertations

First year death rates remain unacceptable high for the end-stage renal disease (ESRD) population. New effective methods are vital to improve first year morbidity and mortality outcomes for the population transitioning from Stage 4 chronic kidney disease (CKD) to ESRD)/Stage 5 CKD. Based on current methods, evidence-based recommendations made by nephrology providers are frequently not heeded by patients in Stage 4 CKD. Low levels of patient knowledge, self-efficacy, and a poor ability to self-manage CKD negatively influence a patient’s ability to follow provider recommendations. The group visit (GV) intervention has demonstrated improvements in disease-related outcomes through increased levels of patient …


Aqueous Route For The Synthesis Of Platinum, Ruthenium And Ceria Nanoparticles On Multi-Walled Carbon Nanotubes For The Electrooxidation Of Methanol And Ethanol, Jordan M. Anderson, Matthew D. Mcinnis, Astha Malhotra, Lei Zhai Jan 2013

Aqueous Route For The Synthesis Of Platinum, Ruthenium And Ceria Nanoparticles On Multi-Walled Carbon Nanotubes For The Electrooxidation Of Methanol And Ethanol, Jordan M. Anderson, Matthew D. Mcinnis, Astha Malhotra, Lei Zhai

Faculty Bibliography 2010s

The electrochemical oxidation of methanol and ethanol in acidic media was studied using electrodes composed of multi-walled carbon nanotubes (MWCNTs) decorated with Pt, Ru and ceria nanoparticles. Polystyrene sulfonate (PSS) was used to disperse the MWCNTs in water and provide nucleation sites for the growth of catalyst nanoparticles. Composite electrodes were characterized for structural and electrochemical properties and all electrodes modified with Ru displayed greater catalytic ability for alcohol oxidation than those without Ru. In addition, the inclusion of ceria seemed to increase the catalytic ability in every sample suggesting a synergistic effect between Pt, Ru and ceria for the …


Self-Assembled Palladium-Organic Composite Nanofibers And Their Applications As A Recyclable Catalyst, Tanmay Bera, Jiyu Fang Jan 2013

Self-Assembled Palladium-Organic Composite Nanofibers And Their Applications As A Recyclable Catalyst, Tanmay Bera, Jiyu Fang

Faculty Bibliography 2010s

We report the formation of palladium nanoparticle (PdNP)-lithocholic acid (LCA) composite nanofibers by the self-assembly of Pd2+-coordinated LCA molecules and an ex situ reduction. The ex situ reduction by sodium borohydride or ascorbic acid produces the composite nanofibers with PdNPs grown on the surface of LCA nanofibers. The catalytic activity of the PdNP-LCA composite nanofibers in the decolourization of 4-phenyl azo benzoic acid is investigated. We find that the composite nanofibers can be recycled without significantly losing their catalytic activities.


High Performance Negative Dielectric Anisotropy Liquid Crystals For Display Applications, Yuan Chen, Fenglin Peng, Takashi Yamaguchi, Xiaolong Song, Shin-Tson Wu Jan 2013

High Performance Negative Dielectric Anisotropy Liquid Crystals For Display Applications, Yuan Chen, Fenglin Peng, Takashi Yamaguchi, Xiaolong Song, Shin-Tson Wu

Faculty Bibliography 2010s

We review recent progress in the development of high birefringence (Delta n > = 0.12) negative dielectric anisotropy (Delta epsilon < 0) liquid crystals (LCs) for direct-view and projection displays. For mobile displays, our UCF-N2 (low viscosity, negative Delta epsilon, high Delta n) based homogeneous alignment fringe-field switching (called n-FFS) mode exhibits superior performance to p-FFS in transmittance, single gamma curve, cell gap insensitivity, and negligible flexoelectric effect. For projection displays using a vertical alignment liquid-crystal-on-silicon (VA LCOS), our high birefringence UCF-N3 mixture enables a submillisecond gray-to-gray response time, which is essential for color sequential displays without noticeable color breakup. Our low viscosity UCF-N2 also enables multi-domain VA displays to use a thinner cell gap for achieving faster response time.


Label-Free Cell Phenotypic Assessment Of The Molecular Mechanism Of Action Of Epidermal Growth Factor Receptor Inhibitors, Huayun Deng, Chaoming Wang, Ye Fang Jan 2013

Label-Free Cell Phenotypic Assessment Of The Molecular Mechanism Of Action Of Epidermal Growth Factor Receptor Inhibitors, Huayun Deng, Chaoming Wang, Ye Fang

Faculty Bibliography 2010s

Epidermal growth factor receptor (EGFR) is the target of several clinically approved tyrosine kinase inhibitor (TKI) drugs including gefitinib and erlotinib in the treatment of cancer. Multiple mechanisms have been implicated in the clinical features of these drugs. However, little is known about the molecular mechanism of action of these drugs at the whole cell level. Here we applied a label-free biosensor-enabled dynamic mass redistribution (DMR) assay to assess the molecular mechanism of action of three EGFR inhibitors, gefitinib, erlotinib and AG1478, to alter the EGFR signaling in A431 and HT-29, two native cancer cell lines expressing the EGFR. The …


Non-Local Coherent Coupling Between Excitons In A Disordered Quantum Well, Yuri D. Glinka, Mikhail Erementchouk, Chandriker K. Dass, Michael N. Leuenberger, Allan S. Bracker, Xiaoqin Li Jan 2013

Non-Local Coherent Coupling Between Excitons In A Disordered Quantum Well, Yuri D. Glinka, Mikhail Erementchouk, Chandriker K. Dass, Michael N. Leuenberger, Allan S. Bracker, Xiaoqin Li

Faculty Bibliography 2010s

We investigated coherent coupling among multiple exciton resonances formed in a single disordered quantum well using the powerful electronic two-dimensional Fourier transform spectroscopy. Our experiment revealed clear signatures of non-local coherent coupling between the heavy-hole and light-hole excitons residing in regions that differ in thickness by one atomic layer. The experimental observation is qualitatively explained by spatial overlap between exciton linear response functions calculated within a single defect model.


Correlations Of Indistinguishable Particles In Non-Hermitian Lattices, M. Gräfe, R. Heilmann, R. Keil, T. Eichelkraut, M. Heinrich, S. Nolte, A. Szameit Jan 2013

Correlations Of Indistinguishable Particles In Non-Hermitian Lattices, M. Gräfe, R. Heilmann, R. Keil, T. Eichelkraut, M. Heinrich, S. Nolte, A. Szameit

Faculty Bibliography 2010s

A novel approach to investigate the dynamics of indistinguishable particles in non-Hermitian lattice systems is presented, allowing an efficient calculation of quantum correlations between these particles in the presence of losses. Particular attention is paid to quasi-parity-time-symmetric systems, for which we numerically analyze two-particle quantum random walks for a variety of input states. Our results show how in some scenarios coherence is lost, inducing classical random walks, while in others the characteristic signatures of bosonic and fermionic exchange symmetry prevail.


Anomalous Paths In Quantum Mechanical Path-Integrals, Arne L. Grimsmo, John R. Klauder, Bo-Sture K. Skagerstam Jan 2013

Anomalous Paths In Quantum Mechanical Path-Integrals, Arne L. Grimsmo, John R. Klauder, Bo-Sture K. Skagerstam

Faculty Bibliography 2010s

We investigate modifications of the discrete-time lattice action, for a quantum mechanical particle in one spatial dimension, that vanish in the naive continuum limit but which, nevertheless, induce non-trivial effects due to quantum fluctuations. These effects are seen to modify the geometry of the paths contributing to the path-integral describing the time evolution of the particle, which we investigate through numerical simulations. In particular, we demonstrate the existence of a modified lattice action resulting in paths with any fractal dimension, d(f), between one and two. We argue that d(f) = 2 is a critical value, and we exhibit a type …


High Power And Spectral Purity Continuous-Wave Photonic Thz Source Tunable From 1 To 4.5 Thz For Nonlinear Molecular Spectroscopy, J. Kiessling, I. Breunig, P. G. Schunemann, K. Buse, K. L. Vodopyanov Jan 2013

High Power And Spectral Purity Continuous-Wave Photonic Thz Source Tunable From 1 To 4.5 Thz For Nonlinear Molecular Spectroscopy, J. Kiessling, I. Breunig, P. G. Schunemann, K. Buse, K. L. Vodopyanov

Faculty Bibliography 2010s

We report a diffraction-limited photonic terahertz (THz) source with linewidth < 10 MHz that can be used for nonlinear THz studies in the continuous wave (CW) regime with uninterrupted tunability in a broad range of THz frequencies. THz output is produced in orientation-patterned (OP) gallium arsenide (GaAs) via intracavity frequency mixing between the two closely spaced resonating signal and idler waves of an optical parametric oscillator (OPO) operating near lambda = 2 mu m. The doubly resonant type II OPO is based on a periodically poled lithium niobate (PPLN) pumped by a single-frequency Yb:YAG disc laser at 1030 nm. We take advantage of the enhancement of both optical fields inside a high-finesse OPO cavity: with 10 W of 1030 nm pump, 100 W of intracavity power near 2 mu m was attained with GaAs inside cavity. This allows dramatic improvement in terms of generated THz power, as compared to the state-of-the art CW methods. We achieved > 25 mu W of single-frequency tunable CW THz output power scalable to > 1 mW with proper choice of pump laser wavelength.

Nanoscale Design Of Nano-Sized Particles In Shape-Memory Polymer Nanocomposites Driven By Electricity, Haibao Lu, Wei Min Huang, Fei Liang, Kai Yu

Faculty Bibliography 2010s

In the last few years, we have witnessed significant progress in developing high performance shape memory polymer (SMP) nanocomposites, in particular, for shape recovery activated by indirect heating in the presence of electricity, magnetism, light, radio frequency, microwave and radiation, etc. In this paper, we critically review recent findings in Joule heating of SMP nanocomposites incorporated with nanosized conductive electromagnetic particles by means of nanoscale control via applying an electro-and/or magnetic field. A few different nanoscale design principles to form one-/two-/three-dimensional conductive networks are discussed.

Faculty Bibliography 2010s

We experimentally observe anomalous wavepacket evolution in a realization of a one-dimensional finite binary Anderson model in the presence of short-range correlations. To this end, we employ weakly-coupled optical waveguides with propagation constants epsilon(1) and epsilon(2). The correlations enforce the creation of dimers, i.e. two adjacent waveguides with the same epsilon, randomly placed along the lattice. A transition from a ballistic to a superdiffusive wavepacket expansion and, eventually, to localization is observed as the contrast between the two propagation constants increases.

Previous medical experiments illustrated that Valence and Arousal were high corresponded to brain response by amygdala and orbital frontal cortex through observation by functional magnetic resonance imaging (fMRI). In this paper, Valence-Arousal related fMRI data-set were acquired from the picture stimuli experiments, and finally the relative Valence -Arousal feature values for a given word that corresponding to a given picture stimuli were calculated. Gaussian bilateral filter and independent components analysis (ICA) based Gaussian component method were applied for image denosing and segmenting; to construct the timing signals of Valence and Arousal from fMRI data-set separately, expectation maximal of Gaussian mixed …


A Generalized Electrodynamics Model For Surface Enhanced Raman Scattering And Enhanced/Quenched Fluorescence Calculations, Haining Wang, Shengli Zou Jan 2013

A Generalized Electrodynamics Model For Surface Enhanced Raman Scattering And Enhanced/Quenched Fluorescence Calculations, Haining Wang, Shengli Zou

Faculty Bibliography 2010s

A generalized electrodynamics model is proposed to describe the enhancement and quenching of the fluorescence signal of a dye molecule placed near a metal nanoparticle (NP). Both the size of the NP and quantum yield of the dye molecule are crucial in determining the emission intensity of the molecule. Changing the size of the metal NP will alter the ratio of the scattering and absorption cross sections of the metal NP and consequently results in different enhancement or quenching effect to the dye molecule. A dye molecule with a reduced quantum yield indicates that the non-radiative channel is dominant in …

Modeling Of Biorefinery Supply Chain Economic Performance With Discrete Event Simulation, Joseph S. Amundson Jan 2013

Modeling Of Biorefinery Supply Chain Economic Performance With Discrete Event Simulation, Joseph S. Amundson

Theses and Dissertations--Manufacturing Systems Engineering

As competition for fossil fuels accelerates, alternative sources of chemicals, fuels, and energy production become more appealing to researchers and the layman. Among the candidates to fill this growing niche is lignocellulosic biomass. Many researchers have examined supply chain design and optimization for biofuel and bioenergy production throughout the years. However, these models often fail to capture the variability and uncertainty inherent to the biomass supply chain. Multiple factors with high degrees of stochasticity can have major impacts on the performance of a biorefinery: weather, biomass quality, feedstock availability, and market demand for products are just a few. To begin …


Preserving Skin Integrity By Utilizing Unit-Specific Wound Care Champions For Pressure Ulcer-Prevention, Christine A. Fanelli Jan 2013

Preserving Skin Integrity By Utilizing Unit-Specific Wound Care Champions For Pressure Ulcer-Prevention, Christine A. Fanelli

Evidence-Based Practice Project Reports

It is estimated that the incidence of pressure ulcers range from 0.4 to 38% in a hospital setting. Overall prevalence in the U.S. was 12.3% in 2009. A CMS analysis reported that pressure ulcers were responsible for over $2.41 billion dollars (Niederhauser et al., 2012). A large body of literature related to pressure ulcer incidence and prevalence reflects that education is not always the principal influencing factor for prevention; social and organizational barriers are just as critical when adapting clinical practice guidelines. To address these barriers, an evidence-based practice (EBP) project was implemented at a large, tertiary hospital in the …
