Video Object Extraction Using The Curvelet Transform, Usama Sayed, Mahmoud A. Mofaddel, Marwa M. Abd-Elgawad

Applied Mathematics & Information Sciences

In this paper a novel scheme for video object extraction based on the second generation of the curvelet transform which is called Fast Discrete Curvelet Transform (FDCT) via wrapping is introduced. The main advantages of using FDCT are the approximate properties and the high directional sensitivity of this transform. An imaginary component of the curvelet coefficients to extract the moving objects in the video sequence is used. The proposed algorithm is mainly divided into two steps. The first step is based on estimating the static background from the initial frames using FDCT, the seconded step is based on subtracting the …

The influences of heat and chemical reactions on blood flow are also taken into account. The governing equations of motion, energy and concentration are simplified by using the long wavelength and low Reynolds number approximations. The analytical solutions of these equations are obtained by considering a perturbation technique for small non- Newtonian Sisko fluid parameter. The pressure rise and friction force are numerically calculated. The numerical calculations with the …

An Interactive Method For Solving Multiple Objective Linear Fractional Programming Problem Based On Linear Optimization Models, Tahere Hossein-Abadi, Ali Payan

Applied Mathematics & Information Sciences

This study aims to present an interactive method in order to solve multiple objective linear fractional programming problem (MOLFPP) according to the linear optimization models. Based on the nonlinear nature of the MOLFPP, presenting interactive methods to solve this problem usually involves long, massive, and complex calculation processes. In this paper, the MOLFPP turns into a linear programming problem (LPP) by disregarding some facts (by considering some negligence) through a linearization process. Then, the answer obtained from the new LPP is tested by an LPP in order to determine whether it is efficient or not. Finally, an efficient or dominant …

Hydrothermal Single Crystal Growth And Characterization Of Novel Rare Earth Niobates And Tantalates: Lnnbo4 (Ln = La-Lu , Y), La2tao5(Oh) And Ln3ta2o9(Oh), Liurukara D. Sanjeewa, Kyle Fulle, Colin D. Mcmillen, Joseph W. Kolis

Chemistry Annual Research Symposium

Rare-earth niobates and tantalates are refractory materials that have been exploited in applications involving ion conductivity, photo-catalysis, and luminescence, both in doped and un-doped forms.

In general, refractory oxides have high melting points therefore synthesis of single crystals are more challenging. For example LnNbO4 can be grown readily by melt techniques such as Czochralski pulling ~1300 ˚C. However during the cooling crystal quality degraded resulting low quality crystals therefore high temperature melting techniques are not suitable for bulk single crystals growth.

Understanding The Role Of Nadh In Cellular Fe2+ Generation Of Hydroxyl Radical And The Effects Of Polyphenol Antioxidants, Craig Goodman, Julia L. Brumaghim

Chemistry Annual Research Symposium

Structurally similar polyphenols have opposite effects on rates of Fe3+ reduction by NADH. In future work, we anticipate exploring several avenues:

What is the role of autoxidation? UV-vis kinetic experiments in an air-free atmosphere should reveal if MEGA is increasing the pool of reducible Fe3+.

What occurs in the presence of H2O2 and/or increased levels of NADH? Mimicking the environment of a stressed cell should yield interesting information about antioxidant activity if the rates change significantly.

Recent Advances In The Synthesis And Application Of Sf5-Containing Organic Compounds, Andrej V. Matsnev, Steven P. Belina, Si-Yan Qing, Kyle A. Berger, Anthony R. Scavuzzo, Piotr Dudzinski, Anna-Lena Dreier, Günter Haufe, Joseph S. Thrasher

Chemistry Annual Research Symposium

It is well known that fluorinated molecules play an important role in daily life. For example, organic molecules bearing either a fluorine atom itself or a short polyfluorinated substituent such as mono-, difluoro-, and trifluoromethyl groups, or pentafluoroethyl and perfluoropropyl groups are already widely used in medicinal and agricultural chemistry. In contrast, molecules with long perfluorinated chains have found vast application in materials science. Among the fluorine-containing moieties, the pentafluorosulfanyl (SF5) substituent occupies a special place.1 The pentafluorosulfanyl group brings unique properties to organic compounds and often improves their biological activities due to the group’s high chemical and metabolic stability, …

A Conceptual Model For Video Games And Interactive Media, Rachel I. Clarke, Jacob Jett, Simone Sacchi, Jin Ha Lee

School of Information Studies - Faculty Scholarship

In this paper, we describe a conceptual model for video games and interactive media. Existing conceptual models such as the Functional Requirements for Bibliographic Records (FRBR) are not adequate to represent the unique descriptive attributes, levels of variance, and relationships among video games. Previous video game-specific models tend to focus on the development of video games and their technical aspects. Our model instead attempts to reflect how users such as game players, collectors, and scholars understand video games and the relationships among them. We specifically consider use cases of gamers, with future intentions of using this conceptual model as a …

Dissolved Oxygen Monitoring In Kings River And Leatherwood Creek, Eric Cummings, Erin E. Scott, Marty Matlock, Brian E. Haggard

Arkansas Water Resources Center Technical Reports

The Clean Water Act (CWA) establishes the basic structure used to regulate water quality. Under the CWA, States are required to assess water bodies relative to water‐quality standards and designated beneficial uses and then to submit lists of impaired bodies every other year to the US Environmental Protection Agency (USEPA). In 2015, at least 4,800 water bodies were listed as impaired by dissolved oxygen across the US (USEPA, 2015). Aquatic species like fish and macroinvertebrates depend on adequate dissolved oxygen for survival. Low dissolved oxygen can lead to fish kills, reduced aquatic diversity, and nuisance smells from anaerobic conditions – …

The method is based on the pyrolysis (1000 ºC under a mixture of 95% Ar / 5% H2 for 1 hour) of paper strips modified with a saturated solution of CuSO4 and yields to the formation of abundant CuNPs on the surface of carbonized cellulose fibers. The resulting substrates were characterized by a combination of scanning electron microscopy, EDX, Raman spectroscopy as well as electrical and electrochemical techniques. Their potential application, as working electrodes for non-enzymatic amperometric determination of glucose, was …

A Smart Polymer Hydrogel As A Chemical Sensor On Biomedical Implant, Md Arifuzzaman, Caleb Behrend, John Desjardins, Jeffrey N. Anker

Chemistry Annual Research Symposium

Orthopedic implants are manufactured to support on healing fractured bones. In United States, over 2 million fracture fixation devices, including intra-medullary nails, external fixation pins, plates, and screws, and over 600 thousands joint prostheses, are implanted in patients annually. While fairly common, these fixation surgeries (5%) sometimes lead to unavoidable infection, which only amplifies health care costs accumulated from the initial procedures. In most cases, bacterial biofilms acutely causes infection which is a major reason of medical device failure. In order to obtain proper infections detection around biomedical implants a non-invasive chemical sensor is required. In vivo detection of low …

Electrochemically-Preadsorbed Collagen Promotes Adult Human Mesenchymal Stem Cell Adhesion On Carbon Nanostructured Substrates, Tomás E. Benavidez, Marissa E. Wechsler, Madeleine M. Farrer, Rena Bizios, Carlos D. Garcia

Chemistry Annual Research Symposium

The effect of electric potential on the adsorption of collagen type I onto optically transparent carbon electrodes (OTCE) and its mediation on subsequent adhesion of adult, human, mesenchymal stem cells (hMSCs) is described. Adsorption was investigated as a function of the protein concentration and applied potential. The resulting substrate surfaces were characterized using spectroscopic ellipsometry (SE), atomic force microscopy (AFM), and cyclic voltammetry (CV). While the higher applied potential and protein concentration, the higher the adsorbed amount, the application of potential values higher than +800 mV resulted in the oxidation of the adsorbed protein. Subsequent adhesion of hMSCs on the …

In order to meet this demand the authors propose using a liquid sampling-atmospheric pressure glow discharge (LS-APGD) ion source, Fig 1.1-3 The LS-APGD was optimized for isotope ratio analysis to have a liquid flow rate of 30 uL min-1 a gas flow rate of 0.5 …

Investigation Of Ionic And Electronic Conductivities In Modified Carbon/Zirconia Composites, Jamie A. Shetzline, Jung-Min Oh, Stephen E. Creager

Chemistry Annual Research Symposium

Ionic and electronic conductivities were recently shown to be able to be independently probed utilizing a near-DC based method for free standing thin films containing mixtures of nafion and carbon black. Recently the mixed conductivity methodology was extended to packed powders in order to study ionic and electronic conductivities of carbon/zirconia nano composite materials for which molecular and polymer electrolytes were covalently grafted onto the carbon/zirconia particle surfaces. The method relies upon careful control of the nature of the contact between the sample and the current-carry-ing electrodes, as well as the geometry of the sample configuration.

New Perspectives On Nonlinear Multi-Atoms Interacting With A Cavity Field, Y. S. El-Saman, S. Abdel-Khalek, A. Badawi, M. Abdel-Aty

Applied Mathematics & Information Sciences

We investigate the entanglement dynamics of two two-level atoms interacting with a quantized cavity field, considering the level shifts produced by the Stark effect.We perform comparisons of the entanglement evolution of this system when the cavity is filled with a Kerr-like medium. The presence of entanglement sudden death and sudden birth using extended Werner-like states is observed. Entanglement is guaranteed to survive and can be easily adapted to allow for periodic behavior. The similar dynamic relations between both the Kerr-like medium and the Stark-shift models are shown.
