Local Geometry Of Zero Sets Of Holomorphic Functions Nears The Torus, Jim Agler, John E. Mccarthy, Mark Stankus

Mathematics

We call a holomorphic function f on a domain in Cⁿ locally toral at the point P in the n-torus if the intersection of the zero set of f with the n-torus has dimension n−1 at P. We study the interplay between the structure of locally toral functions and the geometry of their zero sets.

Sheaf Theoretic Formulation Of Entanglement, Goro C. Kato

Mathematics

A formulation in terms of sheaf theoretic (or categorical) notions for quantum entanglement is given with direct experimental consequences. The notions from sheaf theory and category theory give structural theory, i.e., qualitative theory, as a candidate for quantum gravity. Its advantage is the following: it provides not only space-time background independent, but also scale independent.This theory is called the theory of temporal topos (or simply t-topos theory).

Microcosm To Macrocosm Via The Notion Of A Sheaf (Observers In Terms Of T-Topos), Goro Kato

Mathematics

The fundamental approach toward matter, space and time is that particles (either objects of macrocosm or microcosm), space and time are all presheafified. Namely, the concept of a presheaf is most fundamental for matter, space and time. An observation of a particle is represented by a morphism from the observed particle (its associated presheaf) to the observer (its associated presheaf) over a specified object (called a generalized time period) of a t-site (i.e. a category with a Grothendieck topology). This formulation provides a scale independent and background space-time free theory (since, for the t-topos theoretic formulation, space and time are …

A Positive Mass Theorem On Asymptotically Hyperbolic Manifolds With Corners Along A Hypersurface, Vincent Bonini, Jie Qing

Mathematics

In this paper we take an approach similar to that in [13] to establish a positive mass theorem for spin asymptotically hyperbolic manifolds admitting corners along a hypersurface. The main analysis uses an integral representation of a solution to a perturbed eigenfunction equation to obtain an asymptotic expansion of the solution in the right order. This allows us to understand the change of the mass aspect of a conformal change of asymptotically hyperbolic metrics.

A Manifold Structure For The Group Of Orbifold Diffeomorphisms Of A Smooth Orbifold, Joseph E. Borzellino, Victor Brunsden

Mathematics

For a compact, smooth C^r orbifold (without boundary), we show that the topological structure of the orbifold diffeomorphism group is a Banach manifold for 1 ≤ r < ∞ and a Fréchet manifold if r = ∞. In each case, the local model is the separable Banach (Fréchet) space of C^r (C ^∞, resp.) orbisections of the tangent orbibundle.

User Driven Two-Dimensional Computer-Generated Ornamentation, Dustin Anderson, Zoë J. Wood

Computer Science and Software Engineering

Hand drawn ornamentation, such as floral or geometric patterns, is a tedious and time consuming task that requires skill and training in ornamental design principles and aesthetics. Ornamental drawings both historically and presently play critical roles in all things from art to architecture, and when computers handle the repetition and overall structure of ornament, considerable savings in time and money can result. Due to the importance of keeping an artist in the loop, we present an application, designed and implemented utilizing a user-driven global planning strategy, to help guide the generation of two-dimensional ornament. The system allows for the creation …

Improving Knowledge Retention In A Technical Subject By Diversifying The Learning Experience, Lubomir Stanchev

Computer Science and Software Engineering

There is no silver bullet when it comes to successful teaching. Some scholars believe that traditional lectures are the panacea, while others are firm believers in active and cooperative learning. In this paper I report on my experience with the two approaches and explore the idea of combining them. In particular, I will argue that diversifying the avenues in which students are exposed to knowledge in a technical discipline, such as computer science, can spark their enthusiasm and make the learning experience more enjoyable and productive.

A Translation Engine In Support Of Context-Level Interoperability, Kym J. Pohl, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

The support of context-level interoperability demands increasing attention in today’s arena of semantics-oriented decision-support systems. Unlike data-oriented exchange, such semantic interoperability must venture beyond the elementary communication of discrete data values and endeavor to translate between significantly more expressive, context-rich representations. Further, support of this level of interoperability must not require a contamination of the native perspective embedded within each participant’s representation. Offered as a foundation upon which specific interoperability solutions can be developed, this paper presents a service-oriented framework supporting an extensible set of translation paradigms to effectively connect expressive ontology-based environments. Fundamental to this capability is the notion …

Flash: A Rapid Method For Prototyping Paper-Based Microfluidic Devices, Andres W. Martinez, Scott T. Phillips, Benjamin J. Wiley, Malancha Gupta, George M. Whitesides

Chemistry and Biochemistry

This article describes FLASH (Fast Lithographic Activation of Sheets), a rapid method for laboratory prototyping of microfluidic devices in paper. Paper-based microfluidic devices are emerging as a new technology for applications in diagnostics for the developing world, where low cost and simplicity are essential. FLASH is based on photolithography, but requires only a UV lamp and a hotplate; no clean-room or special facilities are required (FLASH patterning can even be performed in sunlight if a UV lamp and hotplate are unavailable). The method provides channels in paper with dimensions as small as 200 μm in width and 70 μm in …

Radial Velocities Of Giant Stars: An Investigation Of Line Profile Variations, S. Hekker, I. A. G. Snellen, C. Aerts, A. Quirrenbach, S. Reffert, D. S. Mitchell

Physics

Since 1999, a radial velocity survey of 179 red giant stars is ongoing at Lick Observatory with a one month cadence. At present~20—100 measurements have been collected per star with an accuracy of 5 to 8 ms^-1. Of the stars monitored, 145 (80%) show radial velocity (RV) variations at a level >20 ms^-1, of which 43 exhibit significant periodicities. Here, we investigate the mechanism causing the observed radial velocity variations. Firstly, we search for a correlation between the radial velocity amplitude and an intrinsic parameter of the star, in this case surface gravity (logg). …

Scale-Distortion Inequalities For Mantissas Of Finite Data Sets, Arno Berger, Theodore P. Hill, Kent E. Morrison

Research Scholars in Residence

In scientific computations using floating point arithmetic, rescaling a data set multiplicatively (e.g., corresponding to a conversion from dollars to euros) changes the distribution of the mantissas, or fraction parts, of the data. A scale-distortion factor for probability distributions is defined, based on the Kantorovich distance between distributions. Sharp lower bounds are found for the scale-distortion of n-point data sets, and the unique data set of size n with the least scale-distortion is identified for each positive integer n. A sequence of real numbers is shown to follow Benford’s Law (base b) if and only if the scale-distortion (base b) …

Tomography Of The Darcy Velocity From Self-Potential Measurements, A. Jardani, A. Revil, A. Bolève, A. Crespy, J.-P. Dupont, W. Barrash, Bwalya Malama

Natural Resources Management and Environmental Sciences

An algorithm is developed to interpret self-potential (SP) data in terms of distribution of Darcy velocity of the ground water. The model is based on the proportionality existing between the streaming current density and the Darcy velocity. Because the inverse problem of current density determination from SP data is underdetermined, we use Tikhonov regularization with a smoothness constraint based on the differential Laplacian operator and a prior model. The regularization parameter is determined by the L-shape method. The distribution of the Darcy velocity depends on the localization and number of non-polarizing electrodes and information relative to the distribution of the …

Markov-Based Lane Positioning Using Intervehicle Communication, Thanh-Son Dao, Keith Yu Kit Leung, Christopher M. Clark, Jan Paul Huissoon

Computer Science and Software Engineering

The majority of today's navigation techniques for intelligent transportation systems use global positioning systems (GPS) that can provide position information with bounded errors. However, due to the low accuracy that is experienced with standard GPS, it is difficult to determine a vehicle's position at lane level. Using a Markov-based approach based on sharing information among a group of vehicles that are traveling within communication range, the lane positions of vehicles can be found. The algorithm's effectiveness is shown in both simulations and experiments with real data.

Bioluminescence In A Complex Coastal Environment: 1. Temporal Dynamics Of Nighttime Water-Leaving Radiance, Mark A. Moline, Matthew J. Oliver, Curtis D. Mobley, Lydia Sundman, Thomas J. Bensky, Trisha Bergmann, W. Paul Bissett, James Case, Erika H. Raymond, Oscar M.E. Schofield

Physics

Nighttime water-leaving radiance is a function of the depth-dependent distribution of both the in situ bioluminescence emissions and the absorption and scattering properties of the water. The vertical distributions of these parameters were used as inputs for a modified one-dimensional radiative transfer model to solve for spectral bioluminescence water-leaving radiance from prescribed depths of the water column. Variation in the water-leaving radiance was consistent with local episodic physical forcing events, with tidal forcing, terrestrial runoff, particulate accumulation, and biological responses influencing the shorter timescale dynamics. There was a >90 nm shift in the peak water-leaving radiance from blue (~474 nm) …

Effects Of Dependency Injection On Maintainability, Ekaterina Razina, David S. Janzen

Computer Science and Software Engineering

Software maintenance consumes around 70% of the software life cycle. Improving software maintainability could save software developers significant time and money. This paper examines whether the pattern of dependency injection significantly reduces dependencies of modules in a piece of software, therefore making the software more maintainable. This hypothesis is tested with 20 sets of open source projects from sourceforge.net, where each set contains one project that uses the pattern of dependency injection and one similar project that does not use the pattern. The extent of the dependency injection use in each project is measured by a new Number of DIs …

Camp: A Common Api For Measuring Performance, Mark Gabel, Michael Haungs

Computer Science and Software Engineering

Accurate performance testing of heterogeneous distributed systems, such as those created using GRID technology, requires a consistent method for retrieving system performance data from multiple platforms. This paper presents CAMP: a low-level platform independent performance data API designed for use with distributed testing frameworks.

CAMP is not necessarily tied to the distributed testing task: it provides a simple, low-level interface into operating system performance data that can be used to build complex performance measurement applications. This paper discusses CAMP's functionality and implementation in detail. It also contains a detailed analysis of the API's correctness, performance, and overhead.

Spectacular Shells In The Host Galaxy Of The Qso Mc2 1635+119, Gabriela Canalizo, Nicola Bennert, Bruno Jungwiert, Alan Stockton, François Schweizer, Mark Lacy, Chien Peng

Physics

We present deep HST ACS images and Keck spectroscopy of MC2 1635+119, a QSO hosted by a galaxy previously classified as an undisturbed elliptical galaxy. Our new images reveal dramatic shell structure indicative of a merger event in the relatively recent past. The brightest shells in the central regions of the host are distributed alternately in radius, with at least two distinct shells on one side of the nucleus and three on the other, out to a distance of ~13 kpc. The light within the five shells comprises ~6% of the total galaxy light. Lower surface brightness ripples or tails …

Interactive Thin Shells – A Model Interface For The Analysis Of Physically-Based Animation, James Skorupski, Zoë J. Wood, Alex Pang

Computer Science and Software Engineering

Realism has always been a goal in computer graphics. However, the algorithms involved in mimicking the physical world are often complex, abstract, and sensitive to changes in experimental parameters. We present an interface to a physically-based algorithm, a thin shell animation, which focuses on visualization, experimentation, and control. Through the use of dynamic surface coloring, abstract visual cues, robust user interaction, and full control over the algorithm parameters, our system facilitates experimentation and the process of discovery. The system is targeted at enhancing the user’s learning experience by clarifying interactions between various components of many physically-based animations.

Uncertainty As The Source Of Knowledge Transfer Opportunity, Alex Dekhtyar, Jane Huffman Hayes, Judy Goldsmith

Computer Science and Software Engineering

Uncertainty creeps into the software development process in many ways, shapes and forms. In the early stages of software development, key sources of uncertainty are the human stakeholders who help formulate the requirements of the software product. An added layer of uncertainty is inherent as requirements analysts have to deal with subjective, and often conflicting, estimates that humans make, estimates that may significantly affect both the software development process and the eventual software product. Our position is two-fold. We stipulate that in situations where analysts (and later developers) have to deal with human evaluations of uncertainty, special methods and procedures …

The Spin Axes Orbital Alignment Of Both Stars Within The Eclipsing Binary System V1143 Cyg Using The Rossiter-Mclaughlin Effect, S. Albrecht, S. Reffert, I. Snellen, A. Quirrenbach, D. S. Mitchell

Physics

Context. The Rossiter-McLaughlin (RM) effect, a rotational effect in eclipsing systems, provides unique insight into the relative orientation of stellar spin axes and orbital axes of eclipsing binary systems.

Aims. Our aim is to develop a robust method to analyze the RM effect in an eclipsing system with two nearly equally bright components. This gives access to the orientation of the stellar rotation axes and may shed light on questions of binary formation and evolution. For example, a misalignment between the spin axes and the angular momentum of the system could bring the observed and theoretical apsidal motion into better …

Dynamics Of Step-Climing With Deformable Wheels And Applications For Mobile Robotics, Alexander Wilhelm, William Melek, Jan Huissoon, Christopher M. Clark, Gerd Hirzinger, Norbert Sporer, Matthias Fuchs

Computer Science and Software Engineering

Wheeled-mobile robots operating in human environments typically encounter small steps. Surmounting steps is normally not considered when determining peak torque needs, yet it can be the maximum requirement. This work looks at the statics and dynamics of this situation to determine the necessary peak torque. It finds that using a dynamic model that includes the wheel elasticity is essential for properly representing a real-world tire. When torque is increased using a step function, energy is stored in the tire-higher tire elasticity eases climbing. Knowledge of this phenomenon could facilitate the use of smaller actuators. The model is numerically integrated and …

Ubiquitous Low-Velocity Layer Atop The 410-Km Discontinuity In The Northern Rocky Mountains, John Jasbinsek, Kenneth Dueker

Physics

Receiver functions from three 30-station IRIS-PASSCAL small-aperture arrays (2–15 km station spacing) operated for 10 months each in the northern Rocky Mountains show a ubiquitous negative polarity P to S conversion just preceding the 410-km discontinuity arrival. Data from the three arrays were sorted into NW, SE, and SW back-azimuth quadrants and stacked to form nine quadrant stacks. Remarkably, the negative polarity arrival (NPA) is apparent in 8 of the 9 quadrant stacks, with 7 of the 8 having well-correlated waveforms. Each quadrant stack also contains clear P to S conversions from the 410- and 660-km discontinuities. Moveout analysis shows …
