Analysis Of Nonequilibrium Hcp Precipitate Growth In Fcc Matrices: Application To Al–Ag, Daniel Finkenstadt, Duane D. Johnson Nov 2029

Analysis Of Nonequilibrium Hcp Precipitate Growth In Fcc Matrices: Application To Al–Ag, Daniel Finkenstadt, Duane D. Johnson

Duane D. Johnson

Hexagonal-close-packed (hcp) γ-precipitates with large aspect ratios form rapidly in some face-centered cubic (fcc) solid-solutions. No model explains the observed time-dependent increase in aspect ratio, nor irregular intermediate growth shapes. We propose a nonequilibrium process involving trapezoidal offshoots (controlled only by energetics) that governs the growth behavior (kinetics) and yields nonequilibrium structures in agreement with observation. Then, combining nucleation theory and diffusion-limited growth both of secondary nuclei and ledges, we derive a general growth equation for γ-precipitates due to solute-segregation to precipitate–matrix interfaces that includes our modification of the Jones–Trivedi model for thickening to account for the slow ...

Compact Dual-Mode Microstrip Band Reject Filters Based On Fractal Geometrytitle, Hayder S. Ahmed Aug 2016

Compact Dual-Mode Microstrip Band Reject Filters Based On Fractal Geometrytitle, Hayder S. Ahmed

Hayder S. Ahmed

In this paper, a new fractal based microstrip dual-mode band stop filter (BSF) has been presented. The proposed filter structure is essentially based on that of the triangular patch resonators with an embedded slit structure. The Koch fractal geometry has been applied to the uncoupled side lengths of the triangular patch resonator. The filter structure has been modeled and its performance is evaluated using the commercially available EM simulator, Sonnet. Results reveal that the resulting dual-mode response is highly dependent on the uncoupled side lengths of the triangular patch resonator. Parametric study has been conducted to explore the effect of ...

Data-Driven Modeling, Control And Tools For Cyber-Physical Energy Systems, Madhur Behl, Achin Jain, Rahul Mangharam

Real-Time and Embedded Systems Lab (mLAB)

Demand response (DR) is becoming increasingly important as the volatility on the grid continues to increase. Current DR approaches are completely manual and rule-based or in- volve deriving first principles based models which are ex- tremely cost and time prohibitive to build. We consider the problem of data-driven end-user DR for large buildings which involves predicting the demand response baseline, evaluating fixed rule based DR strategies and synthesizing DR control actions. We provide a model based control with regression trees algorithm (mbCRT), which allows us to perform closed- loop control for DR strategy synthesis for large commercial buildings. Our data-driven ...

Airborne Lidar Acquisition, Post-Processing And Accuracy-Checking For A 3d Webgis Of Copan, Honduras, Jennifer Von Schwerin, Heather Richards-Rissetto, Fabio Remondino, Maria Grazia Spera, Michael Auer, Nicolas Billen, Lukas Loos, Laura Stelson, Markus Reindel

Anthropology Faculty Publications

Archaeological projects increasingly collect airborne LiDAR data to use as a remote sensing tool for survey and analysis. Publication possibilities for LiDAR datasets, however, are limited due to the large size and often proprietary nature of the data. Fortunately, web-based, geographic information systems (WebGIS) that can securely manage temporal and spatial data hold great promise as virtual research environments for working with and publishing LiDAR data. To test this and to obtain new data for archaeological research, in 2013, the MayaArch3D Project (www.mayaarch3d.org) collected LiDAR data for the archaeological site of Copan, Honduras. Results include: 1) more accurate ...

Zncdmgse As A Materials Platform For Advanced Photonic Devices: Broadband Quantum Cascade Detectors And Green Semiconductor Disk Lasers, Joel De Jesus

All Dissertations, Theses, and Capstone Projects (2014-Present)

The ZnCdMgSe family of II-VI materials has unique and promising characteristics that may be useful in practical applications. For example they can be grown lattice matched to InP substrates with lattice matched bandgaps that span from 2.1 to 3.5 eV, they can be successfully doped n-type, have a large conduction band offset (CBO) with no intervalley scattering present when strained, they have lower average phonon energies, and the InP lattice constant lies in the middle of the ZnSe and CdSe binaries compounds giving room to experiment with tensile and compressive stress. However they have not been studied in ...


Effect Of Temporal Onset Of Mechanical Loading On Tendon To Bone Healing, Determined With A Novel In-Vivo Device, Mark E. Stasiak Feb 2016

Effect Of Temporal Onset Of Mechanical Loading On Tendon To Bone Healing, Determined With A Novel In-Vivo Device, Mark E. Stasiak

All Dissertations, Theses, and Capstone Projects (2014-Present)

Background: Exposure to tensile loading has been shown to maintain tendon/ligament homeostasis, with the tensile modulus of the tissue increasing in response to greater loading frequency, and even decreasing in the absence of load. However after injury or surgical repair the effect of tensile load is controversial, with many studies implicating mechanical loading with impaired healing. It is currently unknown when the tensile loading imparted during rehabilitation exercise, can be safely reintroduced after surgical tendon repair or ligament reconstruction, and at what time point it can most benefit the remodeling process. To investigate the effect of tensile loading protocols ...


Equilibrium Testing Of Rat Tail Tendon: An Analysis Of The Viscoelastic Properties Of Collagen Under Different Strain Points, Joshua C. Witt Feb 2016

Equilibrium Testing Of Rat Tail Tendon: An Analysis Of The Viscoelastic Properties Of Collagen Under Different Strain Points, Joshua C. Witt

Graduate Theses - Biology & Biomedical Engineering

Instantaneous tensile testing and stress-relaxation testing are forms of mechanical testing used to determine the elastic and viscoelastic properties of biological tissue. Equilibrium testing is a form of testing that combines both of these testing approaches at different strain points to determine the elastic properties of a material and also assess their viscoelastic properties in the same test. This testing method is commonly used on highly viscoelastic materials such as cartilage but has never been fully described in dense collagenous materials such as tendon or ligament. This analysis utilizes different strain points selected to capture the classic non-linear behavior of ...

Blind X-Ray Ct Image Reconstruction From Polychromatic Poisson Measurements, Renliang Gu, Aleksandar Dogandžić Jan 2016

Blind X-Ray Ct Image Reconstruction From Polychromatic Poisson Measurements, Renliang Gu, Aleksandar Dogandžić

Electrical and Computer Engineering Publications

We develop a framework for reconstructing images that are sparse in an appropriate transform domain from polychromatic computed tomography (CT) measurements under the blind scenario where the material of the inspected object and incident-energy spectrum are unknown. Assuming that the object that we wish to reconstruct consists of a single material, we obtain a parsimonious measurement-model parameterization by changing the integral variable from photon energy to mass attenuation, which allows us to combine the variations brought by the unknown incident spectrum and mass attenuation into a single unknown mass-attenuation spectrum function; the resulting measurement equation has the Laplaceintegral form. The ...

Journal Selection Procedure: Select The Best Journal To Ensure The Highest Citation, Nader Ale Ebrahim

Nader Ale Ebrahim

Publication in a peer-reviewed journal is the obvious goal of most researchers to reach others in the field, advancing knowledge and encouraging communication between groups with similar research interest. One of the most important—and possibly the least well understood—aspects of the publication process is the choice of a suitable journal that is likely to improve your research visibility and impact. For instance, publishing your article in an Open Access journal means that more people are likely to see it, simply because more people will be able to access it. So, the greater visibility achieved with OA may allow ...

Movement Path Tortuosity In Free Ambulation: Relationships To Age And Brain Disease, William D. Kearns, James L. Fozard, Vilis O. Nams Jan 2016

Movement Path Tortuosity In Free Ambulation: Relationships To Age And Brain Disease, William D. Kearns, James L. Fozard, Vilis O. Nams

William D. Kearns, PhD

Ambulation is defined by duration, distance traversed, number and size of directional changes and the interval separating successive movement episodes; more complex measures of ambulation can be created by aggregating these features. This review article of published findings defines random changes in direction during movement as “movement path tortuosity”, and relates tortuosity to the understanding of cognitive impairments of persons of all ages. Path tortuosity is quantified by subjecting tracking data to fractal analysis, specifically Fractal Dimension (Fractal D), which ranges from a value of 1 when the movement path is perfectly straight to a value of 2 when the ...

Enhanced Indoor Localization System Based On Inertial Navigation, Rasika Lakmal Hettiarachchige Don Jan 2016

Enhanced Indoor Localization System Based On Inertial Navigation, Rasika Lakmal Hettiarachchige Don

Electronic Thesis and Dissertation Repository

An algorithm for indoor localization of pedestrians using an improved Inertial Navigation system is presented for smartphone based applications. When using standard inertial navigation algorithm, errors in sensors due to random noise and bias result in a large drift from the actual location with time. Novel corrections are introduced for the basic system to increase the accuracy by counteracting the accumulation of this drift error, which are applied using a Kalman filter framework.

A generalized velocity model was applied to correct the walking velocity and the accuracy of the algorithm was investigated with three different velocity models which were derived ...


Sustainable P2 Design For Batch-Based Specialty Chemical Manufacture, Brigitte Pastore Jan 2016

Sustainable P2 Design For Batch-Based Specialty Chemical Manufacture, Brigitte Pastore

Theses and Dissertations

A case study has been conducted on the reduction of n-methyl-2-pyrrilodone (NMP) solvent waste in the manufacture of polyimide and polybenzoxazole precursors. The evaluation includes the environmental and economic assessment of solvent recovery and substitution strategies. A two-step distillation process proved effective in recovering 95% of the NMP at a purity of 99.97% from the aqueous solvent waste stream. Yearly operating costs were reduced by 83% and total life cycle emissions were reduced by 44%, due to reduction in virgin NMP use and hazardous waste disposal. With capital acquisition, the recovery option would still result in a net present ...


Granulation Of Biochar For Soil Amendment, Breanna H. M. Bowden-Green Jan 2016

Granulation Of Biochar For Soil Amendment, Breanna H. M. Bowden-Green

Electronic Thesis and Dissertation Repository

Biochar has shown potential as a soil amendment, but is a fine powder that is difficult to handle and would be blown away if applied to soils without modifications. Wet drum granulation of cornstalk biochar using binder solutions of hydroxypropyl methylcellulose was initially investigated, establishing that biochar could be granulated into a form that would be easier to handle and apply effectively to the soil. Biochars from three different feedstocks were then tested along with three binder solutions. The biochar granules were free flowing and relatively strong with a significant yield between a size range of 1 to 4 mm ...


Fabrication Of Micro-Meltblown Filtration Media Using Parallel Plate Die Design, Mohammad A. Hassan Jan 2016

Fabrication Of Micro-Meltblown Filtration Media Using Parallel Plate Die Design, Mohammad A. Hassan

Mohammad Abouelreesh Hassan

Meltblown fibers are typically produced using a die technology based on the slot concept, an extension of the sheet die technology with a series of holes substituting the center rectangular slot of the sheet die. While this prevalent technology has met with considerable success, an economical, facile design would be desirable. In this study a new parallel plate die concept to fabricate micro-meltblown fibers that offers simplicity, ease of use, and low cost was examined. The new die concept had parallel plates forming channels for polymer melt to flow through with a set of air holes surrounding them. This die ...


An Ontology And Integration Framework For Smart Communities, Steven R Ray, Shishir Kinkar, Mark Hennessy Jan 2016

An Ontology And Integration Framework For Smart Communities, Steven R Ray, Shishir Kinkar, Mark Hennessy

Steven R Ray

This paper describes our work concerning the definition of a neutral, abstract ontology, and framework that supports the vision and diverse contexts of a smart community. This framework is composed of a general, core ontology that supports what many are calling the Internet of Things (IoT), a scalable number of extension ontologies to describe various application perspectives, and a mapping methodology to relate external data and/or schemas to our ontology. Finally, we show why this ontology is scalable and generic enough to support a wide range of smart devices, systems, and people.
