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

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 ...

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 ...

Coupling Community Preferences With Hydrologic Evaluation Of Low Impact Development Implementation In An Urban Watershed, Corinna M. Fleischmann, Carol Atkinson-Palombo, Joseph T. Bushey, Eric D. Jackson, David W. Payne

Suburban Sustainability

Stormwater runoff, and its associated pollutants, is a major problem in urban watersheds where the runoff is either channeled into surface water bodies or wastewater treatment plants. One emerging Best Management Practice (BMP) to control stormwater runoff is low impact development (LID). The EPA Stormwater Management Model (SWMM) was used to evaluate the hydrologic effectiveness at a watershed scale of five LID technologies (vegetated swales, bioretention cells, porous pavement, rain barrels and tree boxes) in an existing, typical urban watershed. As implementation focused on public transportation areas, hydrologic effectiveness of runoff reduction was assessed as a function of roadway length ...

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 2016 Graduate Center, City University of New York

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 2016 Graduate Center, City University of New York

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 2016 Rose-Hulman Institute of Technology

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 ...

The Future Of Artificial Intelligence- Do We Have Anything To Fear?, Katina Michael

Professor Katina Michael

Katina Michael discusses the future prospects of artificial intelligence with Fiona Willey. She emphasises the word "artificial" and notes that "decision making" and "simulation" by computers will never be perfect. Currently, researchers are working in the burgeoning area of Machine Learning, Deep Learning and Reinforcement Learning. Well-known theorists and academics like Stephen Hawking, Elon Musk, and Nick Bostrom note the potential for dangerous scenarios to play, even the possibility of the 'end' of humanity through AI. Katina notes that superintelligence will likely play out in the Cloud and how to harness that power might see an opportunity to interface with ...

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

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 ...
