Electromagnetic Scattering Solutions For Digital Signal Processing, Jonathan Blackledge
Electromagnetic Scattering Solutions For Digital Signal Processing, Jonathan Blackledge
Other resources
Electromagnetic scattering theory is fundamental to understanding the interaction between electromagnetic waves and inhomogeneous dielectric materials. The theory unpins the engineering of electromagnetic imaging systems over a broad range of frequencies, from optics to radio and microwave imaging, for example. Developing accurate scattering models is particularly important in the field of image understanding and the interpretation of electromagnetic signals generated by scattering events. To this end there are a number of approaches that can be taken. For relatively simple geometric configurations, approximation methods are used to develop a transformation from the object plane (where scattering events take place) to the …

School of Computing: Dissertations, Theses, and Student Research
The proliferation of biological databases and the easy access enabled by the Internet is having a beneficial impact on biological sciences and transforming the way research is conducted. There are currently over 1,100 molecular biology databases dispersed throughout the Internet. However, very few of them integrate data from multiple sources. To assist in the functional and evolutionary analysis of the abundant number of novel proteins, we introduce the PROFESS (PROtein Function, Evolution, Structure and Sequence) database that integrates data from various biological sources. PROFESS is freely available at http://cse.unl.edu/~profess/. Our database is designed to be versatile and expandable and …

Application Of Hydroxyapatite In Protein Purification, Permai Sari Molyana Yusuf, Kiagus Dahlan, Arief Budi Witarto
Makara Journal of Science
The precursors, Na2HPO4.2H2O and CaCl2.2H2O are used for synthesizing pure hydroxyapatite which less of carbonate content. The high temperature of sintering, about 700o C of temperature, is treated to minimize the carbonate group on hydroxyapatite surface. Carbonate content of hydroxyapatite which is sintered in 700o C is less than 110o C. It indicates an increasing temperature of sintering will increase crystallinity and decrease carbonate content of hydroxapatite. This method gave better way to resulting hydroxyapatite crystal. The patterns of band of SDS PAGE in resulting of Protein Purification by DEAE matrix is also appear in using hydroxyapatite matrix. The other …

Image Fakery Detection Based on Singular Value Decomposition. The growing of image processing technology nowadays make it easier for user to modify and fake the images. Image fakery is a process to manipulate part or whole areas of image either in it content or context with the help of digital image processing techniques. Image fakery is barely unrecognizable because the fake image is looking so natural. Yet by using the numerical computation technique it is able to detect the evidence of fake image. This research is successfully applied the singular value decomposition method to detect image fakery. The image preprocessing …

The Spectroscopic Orbit Of Sao 167450, Visual Companion Of Aa Ceti, Francis C. Fekel, Daryl W. Willmarth
Information Systems and Engineering Management Research Publications
We have determined a spectroscopic orbit for SAO 167450, which is the visual secondary of the W UMa-type eclipsing binary AA Cet, and so the system is quadruple. Radial velocities from the coudé feed and 4 m telescopes at Kitt Peak National Observatory produce an orbit with a period of 25.68 days and an eccentricity of 0.50. We classify both the primary and secondary as G0 subgiant/dwarf stars and find that they are somewhat metal rich relative to the Sun. The high lithium abundances of both components argue that the stars are less than 1 Gyr old. If the components …
On The Behaviour Of Marginal And Conditional Akaike Information Criteria In Linear Mixed Models, Sonja Greven, Thomas Kneib
On The Behaviour Of Marginal And Conditional Akaike Information Criteria In Linear Mixed Models, Sonja Greven, Thomas Kneib
Johns Hopkins University, Dept. of Biostatistics Working Papers
In linear mixed models, model selection frequently includes the selection of random effects. Two versions of the Akaike information criterion (AIC) have been used, based either on the marginal or on the conditional distribution. We show that the marginal AIC is no longer an asymptotically unbiased estimator of the Akaike information, and in fact favours smaller models without random effects. For the conditional AIC, we show that ignoring estimation uncertainty in the random effects covariance matrix, as is common practice, induces a bias that leads to the selection of any random effect not predicted to be exactly zero. We derive …

Beauty, Ugliness, And Meaning: A Study Of Difficult Beauty, Christine Anne Palmer
Beauty, Ugliness, And Meaning: A Study Of Difficult Beauty, Christine Anne Palmer
Theses and Dissertations
The emergence of modern art, and subsequently contemporary art, has brought with it a deep-rooted deliberation of the definition of beauty and its role in the realm of art. Unlike many representational artworks, contemporary art less often contains a beauty that is readily available on the surface of an artwork- an easy beauty. Instead, it often possesses a beauty that requires substantial reasoning and understanding- a difficult beauty. Just as the definition of beauty has and will continue to be culturally and historically changing, so must our methodological and pedagogical practices in regards to beauty and Aesthetics. As Art Educators, …

Vision-Based Precision Landings Of A Tailsitter Uav, Paul Travis Millet
Theses and Dissertations
We present a method of performing precision landings of a vertical take-off and landing (VTOL) unmanned air vehicle (UAV) with the use of an onboard vision sensor and information about the aircraft's orientation and altitude above ground level (AGL). A method for calculating the 3-dimensional location of the UAV relative to a ground target of interest is presented as well as a navigational controller to position the UAV above the target. A method is also presented to prevent the UAV from moving in a way that will cause the ground target of interest to go out of view of the …

Presentations Of Rings With Non-Trivial Semidualizing Modules, David A. Jorgensen, Graham J. Leuschke, Sean Sather-Wagstaff
Mathematics - All Scholarship
Let R be a commutative noetherian local ring. A finitely generated R-module C is semidualizing if it is self-orthogonal and satisfies the condition HomR(C,C) \cong R. We prove that a Cohen-Macaulay ring R with dualizing module D admits a semidualizing module C satisfying R\ncong C \ncong D if and only if it is a homomorphic image of a Gorenstein ring in which the defining ideal decomposes in a cohomologically independent way. This expands on a well-known result of Foxby, Reiten and Sharp saying that R admits a dualizing module if and only if R is Cohen-Macaulay and a …

The Security Implication Of Multiple Observers In A Distributed System, Derek P. Ditch, Bruce M. Mcmillin
The Security Implication Of Multiple Observers In A Distributed System, Derek P. Ditch, Bruce M. Mcmillin
Computer Science Faculty Research & Creative Works
Confidentiality is an often overlooked, yet crucial point in the security analysis of a system. infrastructures take for granted that confidentiality is maintained through obfuscation by dissemination of information. This dissemination does indeed maintain the confidentiality of the system when only a small portion of the information can be obtained by an outside observer. However, when multiple observers collaboratively make observations, the confidential information can be revealed or even just partially revealed. If a team of attackers on a system can deduce enough information to successfully perform a crippling attack, the system could not be considered secure. This paper will …

Model-Checking Bndc Properties In Cyber-Physical Systems, Ravi Akella, Bruce M. Mcmillin
Computer Science Faculty Research & Creative Works
In Cyber-physical systems, which are the integrations of computational and physical processes, it is hard to realize certain security properties. Fundamentally, physically observable behavior leads to violations of confidentiality. We focus on analyzing certain non-interference-based security properties to ensure that interactions between the cyber and physical processes preserve confidentiality. a considerable barrier to this analysis is representing the physical system's interactions. in this paper, these physical system properties are encoded into a discrete event system and the combined Cyber-physical system is described using the process algebra SPA. the model checker, CoPS shows BNDC (Bisimulation based Non-Deducibility on Compositions) properties, which …
Evaluating Logical Pluralism, David Pruitt
Evaluating Logical Pluralism, David Pruitt
Theses
Recently some philosophers, in particular J. C. Beall and Greg Restall, have defended a view they refer to as ‘logical pluralism’. This is the position that there are, in fact, several equally good but distinct logical systems according to which different arguments come out valid and invalid. No one system, they claim, is any more ‘correct’ than any other. I will have several criticisms of this view. I first argue that the phenomena of logical recapture causes problems for the pluralist. Somewhat roughly a logic is recaptured if, though all its argument forms were not valid in the full language, …

Ballistic-Ohmic Quantum Hall Plateau Transition In A Graphene P-N Junction, Tony Low
Ballistic-Ohmic Quantum Hall Plateau Transition In A Graphene P-N Junction, Tony Low
Birck and NCN Publications
Recent quantum Hall experiments conducted on disordered graphene p-n junction provide evidence that the junction resistance could be described by a simple Ohmic sum of the n and p mediums’ resistances. However in the ballistic limit, theory predicts the existence of chirality-dependent quantum Hall plateaus in a p-n junction. We show that two distinctively separate processes are required for this ballistic-Ohmic plateau transition, namely, (i) hole/electron Landau states mixing and (ii) valley isospin dilution of the incident Landau edge state. These conclusions are obtained by a simple scattering theory argument, and confirmed numerically by performing ensembles of quantum magnetotransport calculations …
Dihomotopic Reduction Used In Deadlock Detection, David A. Cape, Bruce M. Mcmillin
Dihomotopic Reduction Used In Deadlock Detection, David A. Cape, Bruce M. Mcmillin
Computer Science Faculty Research & Creative Works
Deadlock detection for concurrent programs has traditionally been accomplished by symbolic methods or by search of a state transition system. We examine an approach that uses geometric semantics involving the topological notion of dihomotopy to partition the state-space into components, after which the reduced state-space is exhaustively searched. Prior work partitioned the state-space inductively, but in this paper, we show that a recursive technique provides greater reduction of the size of the state transition system. as a result, we expect to see more efficient deadlock detection and eventually more efficient verification of some temporal properties for large problems if the …
