Green Roofs In The Airport Environment: Pleasant Dreams Or Nightmares?, Ryan M. Swearingin, Craig Pullins, Travis Guerrant, Brian E. Washburn

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

Green roofs on buildings are becoming very popular in urban areas of the United States. Public benefits of green roof projects include stormwater runoff reduction, improved water quality, reduced urban heat island effects, and aesthetic values. Several green roofs have been constructed in downtown Chicago and large-scale green roofs are currently being planned and implemented at O’Hare International Airport (ORD). Similar to any airport landscaping, green roofs on buildings in the airport environment might attract wildlife hazardous to aviation and could increase the risk of bird-aircraft collisions. No information currently exists in regard to this potential problem. During 2007–2008, we …

Geoarchaeological And Paleolandscape Reconstructions In The Lower Ohio River Valley: Late Wisconsin And Early Holocene Landforms In Knob Creek Bottom, Nathan Christopher Scholl

All-Inclusive List of Electronic Theses and Dissertations

This study examines a paleolandscape model that focuses on alluvial landforms that date to the Late Pleistocene and Early Holocene in Knob Creek bottom of the lower Ohio River valley. The study tests and refines a landscape model based on geoarchaeological data from the Caesars Archaeological Project. Analysis centers on the relationship between late Wisconsin and early Holocene Landform Sediment Assemblages (LSA), including early paleochannels. For this analysis a series of soil cores was extracted from the LSA understudy and described using standard USDA terminology. Additional analysis included particle size analysis using a hydrometer to determine textural composition of core …

Role Of Adenine In Thymine-Dimer Repair By Reduced Flavin-Adenine Dinucleotide, Guifeng Li, Vincent Sichula, Ksenija D. Glusac

Chemistry Faculty Publications

We present a study of excited-state behavior of reduced flavin cofactors using femtosecond optical transient absorption spectroscopy. The reduced flavin cofactors studied were in two protonation states: flavin-adenine dinucleotide (FADH(2) and FADH(-)) and flavin-mononucleotide (FMNH2 and FMNH-). We find that FMNH- exhibits multiexponential decay dynamics due to the presence of two bent conformers of the isoalloxazine ring. FMNH2 exhibits an additional fast deactivation component that is assigned to an iminol tautomer. Reduced flavin cofactors also exhibit a long-lived component that is attributed to the semiquinone and the hydrated electron that are produced in photoinduced electron transfer to the solvent. The …

A Mathematical Model Development And Sensitivity Analysis Of Two Photon Polymerization For 3d Micro/Nano Fabrication, Nitin Uppal

Mechanical and Aerospace Engineering Dissertations - Archive

Two photon polymerization (2PP) is an effective technique for the fabrication of complex polymeric 3-D micro/nano features using ultrashort pulses from a NIR laser source. The photosensitive material absorbs two photons and initiates the chain polymerization reaction. The interaction of laser pulses with photo responsive resin creates a voxel (volumetric pixel) which defines the resolution of 2PP process. In this work, a mathematical model of the polymerization process that considers the effects of molecular diffusion and polymerization kinetics on the formation of voxel. The increase in temperature upon polymerization and their effect on the polymerization kinetics and molecular diffusion is …

Error Correction Methods For Latency-Constrained Flash Memory Systems, Priyanka Ankolekar

Electrical Engineering Theses - Archive

Maintaining the reliability of data stored in Flash devices and reading it correctly has become a challenge as the demand for higher density is forcing aggressive shrinking of Flash architectures. For all Flash systems, especially latency-constrained NOR Flash, an on-chip error correction code (ECC) is the only viable and robust solution to this problem. This thesis investigates and optimizes low-latency error correction schemes for on-chip implementation in NOR systems using existing error correction methods as a starting point. As the first step towards doing this, a mathematical relation has been derived to compute the bit error rate (BER) of a …

Remote Sensing Studies For The Assessment Of Geohazards: Toxic Algal Blooms In The Lower Great Lakes, And The Land Subsidence In The Nile Delta, Richard H. Becker

Dissertations

Remote sensing techniques provide valuable tools for assessing a wide variety of environmental phenomena. They have been used for monitoring and assessment of various types of geologic and environmental hazards occurring on land, in the air, or in oceans. I present results from two studies, the first of which examines the spatial and temporal distribution of algal blooms in the Great Lakes; the second measures subsidence in the Nile Delta.

In the first study, methodologies to investigate the extent and distribution (temporally and spatially) of algal blooms in Lake Erie and Lake Ontario are studied. Millions of people in the …

Three-Agent Peer Evaluation, Vicki Knoblauch

Economics Working Papers

I show that every rule for dividing a dollar among three agents impartially (so that each agent's share depends only on her evaluation by her associates) underpays some agent by at least one-third of a dollar for some consistent profile of evaluations. I then produce an impartial division rule that never underpays or overpays any agent by more than one-third of a dollar, and for most consistent evaluation profiles does much better.

Subcellular Structure Modeling And Tracking For Cell Dynamics Study, Quan Wen

Computer Science and Engineering Dissertations - Archive

The introduction of sensitive and fast electronic imaging devices and the development of biological methods to tag proteins of interest by green fluorescent proteins (GFP) have made a full understanding of live cell dynamics achievable. With the latest hardware technology, such as high speed laser scanning confocal Microscopy (LSCM), it has now become critical to develop automatic quantitative data analysis tools to keep pace with and to fully exploit the functionalities of state-of-the-art hardware. One task of such tools is the motility analysis of subcellular structures. This dissertation provides a series of computational approaches for studying subcellular structure motility. Firstly, …

Connectionist Model Generation: A First-Order Approach, Sebastian Bader, Pascal Hitzler, Steffen Holldobler

Computer Science and Engineering Faculty Publications

Knowledge-based artificial neural networks have been applied quite successfully to propositional knowledge representation and reasoning tasks. However, as soon as these tasks are extended to structured objects and structure-sensitive processes as expressed e.g., by means of first-order predicate logic, it is not obvious at all what neural-symbolic systems would look like such that they are truly connectionist, are able to learn, and allow for a declarative reading and logical reasoning at the same time. The core method aims at such an integration. It is a method for connectionist model generation using recurrent networks with feed-forward core. We show in this …

Half-Metallicity In Hybrid Bcn Nanoribbons, Er-Jun Kan, Xiaojun Wu, Zenyu Li, Xiao Cheng Zeng, Jinlong Yang, J. G. Hou

Xiao Cheng Zeng Publications

The established chemical synthetic strategy toward graphene nanoribbons has greatly prompted and justified the research of theoretical designs of novel materials based on graphene. In this paper, we report the novel half-metallicity in C and BN hybrid zigzag nanoribbons even though stand-alone C or BN nanoribbon possesses a finite band gap. By performing first-principles electronic-structure calculations, we find this unexpected half-metallicity in the hybrid nanostructures stems from a competition between the charge and spin polarizations, as well as from the π orbital hybridization between C and BN. Molecular dynamics simulations indicate that the hybrid nanoribbons are stable. Our results point …

Enhanced Bioinformatics Data Modeling Concepts And Their Use In Querying And Integration, Feng Ji

Computer Science and Engineering Dissertations - Archive

In bioinformatics research, scientists usually face the problems of modeling complex data types and integrating diverse resources. Traditional data models such as EER lack the expressing power to capture many characteristics that are common in bioinformatics data. We first propose extensions to the ER model that allow accurate representation of many of these characteristics. We then utilize these concepts in an integrative system to provide an easy-to-use interface for biologists to construct queries. Our research utilizes the enhanced conceptual modeling concepts to create a prototype mediator for querying multiple data sources. The various relationships between different biological entities are all …

Mass Spectrometry-Based Biomolecular Recognition And Response Factor Investigations Using Electrospray Ionization, Misjudeen Raji

Chemistry & Biochemistry Dissertations - Archive

Integrins are transmembrane proteins found in almost all cells. They play vital roles in many biological processes, such as angiogenesis and signal transduction, through their interactions with different extracellular matrix ligands. These interactions are fostered by forming noncovalent bonds with the ligands. Integrin involvement in angiogenic cancer metastasis has sparked the interest of many researchers in the field of oncology. Many cutting edge research works are now focused on studying the noncovalent interactions of integrins with potential drug compounds formulated from peptide mimics and bearing the putative RGD amino acid sequence through which integrins are known to bind their ligands. …

High Order Weighted Compact Boundary Condition, Zhengjie Wang

Mathematics Theses - Archive

In multi-dimension flows, we expect to have problems at the boundaries when a shock hits or reflects at the boundary wall the remedy to this would be to develop weighted boundary conditions similar to the Weighted Compact Scheme for the interior nodes, by choosing candidate stencils around the boundary nodes and assigning weights to each of these stencils with the ENO reconstruction. This would avoid spurious oscillations when shocks are encountered at the boundaries. This thesis investigates higher order weighted compact boundary conditions for Weighted Compact Scheme (WCS). WCS is a combination of Essentially Non Oscillatory Scheme and Weighted Compact …

Computational Analysis Of Expressed Sequence Tags For Understanding Gene Regulation., I. Elizabeth Cha 1973-

Electronic Theses and Dissertations

High-throughput sequencing has provided a myriad of genetic data for thousands of organisms. Computational analysis of one data type, expressed sequence tags (ESTs) yields insight into gene expression, alternative splicing, tissue specificity gene functionality and the detection and differentiation of pseudogenes. Two computational methods have been developed to analyze alternative splicing events and to detect and characterize pseudogenes using ESTs. A case study of rat phosphodiesterase 4 (PDE4) genes yielded more than twenty-five previously unreported isoforms. These were experimentally verified through wet lab collaboration and found to be tissue specific. In addition, thirteen cytochrome-like gene and pseudogene sequences from the …

Clustered Longitudinal Data Analysis., Ming Wang

Electronic Theses and Dissertations

Clustered longitudinal data is often collected as repeated measurements on subjects over time arising in the clusters. Examples include longitudinal community intervention studies, or family studies with repeated measures on each member. Meanwhile, cluster size is sometime informative, which means that the risk for the outcomes is related to the cluster size. Under this situation, generalized estimating equations (GEE) will lead to invalid inferences because GEE assumes that the cluster size is non-informative. In this study, we investigated the performances of generalized estimating equations (GEE), cluster-weighted generalized estimating equations (CWGEE), and within-cluster resampling (WCR) on clustered longitudinal data. Based on …
