Efficient Inverse Design Of Transonic Airfoils Using Variable-Resolution Models And Manifold Mapping, Xiaosong Du, Leifur Leifsson, Slawomir Koziel

Mechanical and Aerospace Engineering Faculty Research & Creative Works

This paper presents an efficient approach for simulation-based inverse design of airfoil shapes using variable-fidelity computational fluid dynamics models and manifold mapping (MM). Inverse design involves determining an airfoil shape fulfilling a given target performance characteristic. In particular, the pressure coefficient distribution is typically used in aerodynamic inverse design. Such a task can be challenging when using computationally expensive simulations. In the context of local optimization, the MM technique searches for a new design in the vicinity of the current design by constructing a fast multi-fidelity model, which is setup by the available evaluations of each of the high- and …

An Improved Infiltration Model And Design Sizing Approach For Stormwater Bioretention Filters Including Anisotropy And Infiltration Into Native Soils, Daniel Macadam

Master's Theses and Capstones

Bioretention filters are a common Best Management Practice used to treat pollutants and water volumes of stormwater runoff from urbanized watersheds. The current static sizing criterium for new design applies Darcy’s law to the Water Quality Volume (WQV) as it filters through the bioretention soil media. In retrofit applications, the WQV is instantaneously stored in the system pore space, including the ponded surface. While these designs are simple to implement, the systems areas are oversized because no infiltration or other outflow is considered in the design.

The retrofit bioretention study site for this research located in Dover, NH (HSBS) treats …

Disposable Printed Lateral Flow Electrochemical Immunosensors For Human Cardiac Troponin T, Eithne Dempsey, Dhanraj Rathod

Articles

Here we report an electrochemical ELISA approach for cardiac Troponin T (cTnT) determination based on a lateral flow membrane with underlying screen printed electrodes (<;100 Ω /cm 2 ). The thick film transducer was modified with the anti-cardiac Troponin T antibody via physisorption and the electrochemical performance of the immunosensor was evaluated using cyclic voltammetry. The capture antibody coated immunoelectrode employed for electrochemical determination of Troponin T antigen used a sandwich assay format with horseradish peroxidase conjugated signaling antibodies held in the track of a lateral flow sensor strip. A simple two step procedure realized signal acquisition within <;20 min (total assay time). The lateral flow electrochemical immunosensor response resulted in a calibration curve with linear response (0-700 ng/ml cTnT) with limit of detection of 0.15 ng/ml.

The Utility And Limits Of Canons Of Construction In Public International Law, Sean D. Murphy

GW Law Faculty Publications & Other Works

This draft chapter, for a volume that considers canons of construction and other interpretive principles in public international law, considers the utility and limits of such canons, drawing in part upon lessons learned from schools of American jurisprudence (formalism, realism, pragmatism) with respect to statutory interpretation. In international law, there are certain obligatory canons of construction that have been expressly incorporated in Articles 31 and 32 of the Vienna Convention on the Law of Treaties. These canons are essential elements of the interpretive process; while in any given context, one or the other of these elements might be favored, they …

Bifurcating Settlements, Michael B. Abramowicz, Sarah Abramowicz

GW Law Faculty Publications & Other Works

In settling a lawsuit, parties agree on their obligations to one another, but they need not separately address each issue, claim, or remedy that a trial court would have confronted. The legal system, however, can bifurcate the settle-ment process, requiring separate resolution of components of a settlement. Bi-furcation can protect third parties, for example, by preventing divorcing parents from trading child custody for money. In addition to identifying a wide range of contexts in which preventing trade-offs may be desirable, this Article shows that bifurcation will generally have only modest (and sometimes beneficial) effects on settlement rates.

Pythagorean Generalization Of Testing The Equality Of Two Symmetric Positive Definite Matrices, Jin Seo Cho, Peter C. B. Phillips

Research Collection School Of Economics

We provide a new test for equality of two symmetric positive-definite matrices that leads to a convenient mechanism for testing specification using the information matrix equality or the sandwich asymptotic covariance matrix of the GMM estimator. The test relies on a new characterization of equality between two k dimensional symmetric positive-definite matrices A and B: the traces of AB−1 and BA−1 are equal to k if and only if A=B. Using this simple criterion, we introduce a class of omnibus test statistics for equality and examine their null and local alternative approximations under some mild regularity conditions. A preferred test …

Epidemiological Model Of The Transmission And Spread Of Hepatitis B Pandemic In Ghana, Kwaafo Akoto Awuah-Mensah

Theses: Doctorates and Masters

The world's attention to the burden and spread of hepatitis B has increased signicantly in the recent past. A number of interventions by way of treatment and immunisation have been initiated to fight the pandemic, especially in high prevalence regions such as Africa and Asia. Lack of good quality information about hepatitis B is a major hindrance to policy direction and comprehensive implementation of interventions in Sub-Saharan Africa designated as an endemic region. Limited studies on hepatitis B, coupled with lack of adequate health care systems and infrastructure, have led to ignorance or misconceptions and stigmatisation about the disease and …

A Coat Of Ashes: A Collection Of Poems, Incorporating A Metafictional Narrative - And - Poetry, Daoism, Physics And Systems Theory: A Poetics: A Set Of Critical Essays, Janet Ruth Jackson

Theses: Doctorates and Masters

This thesis comprises a book-length creative work accompanied by a set of essays. It explores how poetry might bring together spiritual and scientific discourses, focusing primarily on philosophical Daoism (Taoism) and contemporary physics. Systems theory (the science of complex and self-organising systems) is a secondary focus of the creative work and is used metaphorically in theorising the writing process.

The creative work, “A coat of ashes”, is chiefly concerned with the nature of being. It asks, “What is?”, “What am I?” and, most urgently, “What matters?”. To engage with these questions, it opens a space in which voices expressing scientific …

This approach uses a genetic algorithm to evolve a set of modifications that, when …

Extremal Quantile Treatment Effects, Yichong Zhang

Research Collection School Of Economics

This paper establishes an asymptotic theory and inference method for quantile treatment effect estimators when the quantile index is close to or equal to zero. Such quantile treatment effects are of interest in many applications, such as the effect of maternal smoking on an infant’s adverse birth outcomes. When the quantile index is close to zero, the sparsity of data jeopardizes conventional asymptotic theory and bootstrap inference. When the quantile index is zero, there are no existing inference methods directly applicable in the treatment effect context. This paper addresses both of these issues by proposing new inference methods that are …

Application Of 3d Delaunay Triangulation In Fingerprint Authentication System, Wencheng Yang, Ahmed Ibrahim, Junaid Chaudhry, Song Wang, Jiankun Hu, Craig Valli

Research outputs 2014 to 2021

Biometric security has found many applications in Internet of Things (IoT) security. Many mobile devices including smart phones have supplied fingerprint authentication function. However, the authentication performance in such restricted environment has been downgraded significantly. A number of methods based on Delaunay triangulation have been proposed for minutiae-based fingerprint matching, due to some favorable properties of the Delaunay triangulation under image distortion. However, all existing methods are based on 2D pattern, of which each unit, a Delaunay triangle, can only provide limited discrimination ability and could cause low matching performance. In this paper, we propose a 3D Delaunay triangulation based …

How Important Is Groundwater Availability And Stream Perenniality To Riparian And Floodplain Tree Growth?, Neil E. Pettit, Raymond H. Froend

Research outputs 2014 to 2021

Riparian vegetation is important for stream functioning and as a major landscape feature. For many riparian plants, shallow groundwater is an important source of water, particularly in areas where rainfall is low, either annually or seasonally, and when extended dry conditions prevail for all or part of the year. The nature of tree water relationships is highly complex. Therefore, we used multiple lines of evidence to determine the water sources used by the dominant tree species Eucalyptus camaldulensis (river red gum), growing in riparian and floodplain areas with varying depth to groundwater and stream perenniality. Dendrometer bands were used to …

Telomere Correlations During Early Life In A Long Lived Seabird, Jacob Schmidt

Biological Sciences

Telomere dynamics in blood cells have been linked to aging in a variety of organisms. However, whether blood telomeres correlated with telomeres in other parts of the body is not well known, especially during early life when telomere loss is expected to be most rapid. We investigated this question in embryonic and juvenile Franklin’s gulls (Leucophaeus pipixcan). We measured telomere lengths in blood, heart, liver and skeletal muscle tissues at the end of embryonic (n = 31) and post-natal development (n=20). In late-stage embryos, blood telomeres were significantly positively correlated with heart and skeletal muscle, but not liver telomeres. However, …
