Elements Of Human Decision-Making, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

The purpose of this paper is to present some understandings of the human problem-solving activity that we have gained in the Collaborative Agent Design Research Center (CADRC) over the past two decades. Since we feel strongly that the human decision-maker should be an integral component of any computer-based decision-support system, it follows that we would have endeavored to incorporate many of the elements that appear to be important to the user in the design of these systems. The complexity of the human cognitive system is evidenced by the large body of literature that describes problem-solving behavior and the relatively fewer …

How Magnetotactic Bacteria Make Magnetosomes Queue Up, Richard B. Frankel, Dennis A. Bazylinski

Physics

Magnetotactic bacteria contain chains of magnetosomes that comprise a permanent magnetic dipole in each cell. In two separate, recent papers, Scheffel et al. and Komeili et al. describe the roles of the proteins MamJ and MamK in magnetosome chain formation. Here, we describe the two studies and highlight questions that must be addressed in future investigations of how magnetotactic bacteria construct their magnetic compass needles.

The Radio Structure Of Radio-Quiet Quasars, C. Leipski, H. Falcke, N. Bennert, S. Hüttenmeister

Physics

Aims. We investigate the radio emitting structures of radio-quiet active galactic nuclei with an emphasis on radio-quiet quasars to study their connection to Seyfert galaxies. Methods. We present and analyse high-sensitivity VLA radio continuum images of 14 radio-quiet quasars and six Seyfert galaxies. Results. Many of the low redshift radio-quiet quasars show radio structures that can be interpreted as jet-like outflows. However, the detection rate of extended radio structures on arcsecond scales among our sample decreases with increasing redshift and luminosity, most likely due to a lack of resolution. The morphologies of the detected radio emission indicate strong interactions of …

A Genetic Algorithm Approach To Solve For Multiple Solutions Of Inverse Kinematics Using Adaptive Niching And Clustering, Saleh Tabandeh, Christopher M. Clark, William Melek

Computer Science and Software Engineering

Inverse kinematics is a nonlinear problem that may have multiple solutions. A Genetic Algorithm(GA) for solving the inverse kinematics of a serial robotic manipulator is presented. The algorithm is capable of finding multiple solutions of the inverse kinematics through niching methods. Despite the fact that the number and position of solutions in the search space depends on the the position and orientation of the end-effector as well as the configuration of the robot, the number of GA parameters that must be set by a user are limited to a minimum through the use of an adaptive niching method. The only …

Description Of Spherical Aberration And Coma Of A Microlens Using Vector Diffraction Theory, Glen D. Gillen, Shekhar Guha

Physics

Light distributions of a plane wave refracted by a microlens are calculated using Kirchhoff vector diffraction theory. Numerical results for one and two-dimensional beam profiles and the onset and effects of spherical aberration and coma are investigated for different lens parameters.

When Domains Require Modeling Adaptations, Krol Kevin Mathias, Cynthia Isenhour, Alex Dekhtyar, Judy Goldsmtih, Beth Goldstein

Computer Science and Software Engineering

The project described in this paper originated with an observation by the AI group at the University of Kentucky, that, individually, stochastic planning and constraint satisfaction are well-studied topics that resulted in efficient software, but stochastic planning in the presence of constraints on the domains and actions is an open area of investigation.

We were interested in an advising scenario, and chose the US social welfare system, a.k.a. “Welfare to Work” as our test domain. This required computer scientists to learn more than expected about social science as well as the local welfare system. This paper discusses the discipline specific …

Ricci Curvature Rigidity For Weakly Asymptotically Hyperbolic Manifolds, Vincent Bonini, Pengzi Miao, Jie Qing

Mathematics

A rigidity result for weakly asymptotically hyperbolic manifolds with lower bounds on Ricci curvature is proved without assuming that the manifolds are spin. The argument makes use of a quasilocal mass characterization of Euclidean balls from [9] [14] and eigenfunction compactification ideas from [12].

Four of these latter crystals are made with isotopically enriched materials: two in n¹²⁸Te and two …

Algorithms For Sensor Chip Alignment To Blind Datums, Gary B. Hughes

Statistics

The sensor element of an imaging system should be mounted into its housing in such a way that the scene can be properly focused onto the sensor element's focal plane over the active area. Operational imaging requirements are forcing increasingly smaller tolerances on sensor alignment, and manufacturing systems must improve alignment capability to keep pace. Imaging system designs include reference datums that provide the basis for manufacturing alignment of optical components in each subassembly. Design constraints for alignment of the sensor element into the camera housing typically include x,y,z, clocking, and parallelism specifications. Measurement of z and parallelism positioning is …

Physics

Measurements of two-particle correlations on angular difference variables η1−η2 (pseudorapidity) and ϕ1−ϕ2 (azimuth) are presented for all primary charged hadrons with transverse momentum 0.15≤pt≤2 GeV/c and |η|≤1.3 from Au-Au collisions at √sNN=130 GeV. Large-amplitude correlations are observed over a broad range in relative angles where distinct structures appear on the same-side and away-side (i.e., relative azimuth less than π/2 or greater than π/2). The principal correlation structures include that associated with elliptic flow plus a strong, same-side peak. It is hypothesized that the latter results from correlated hadrons associated with semi-hard parton scattering in the early stage of the heavy-ion …

Geotorrent: Optimizing Gis Web Services For Interactive Educational Use, Jeffrey A. Bergamini, Michael Haungs

Computer Science and Software Engineering

Large online geospatial datasets for use with GIS are increasingly available and have many uses, including study in numerous academic and scientific fields. Access to this data in real time for pedagogical purposes would be immensely useful to educators. The academic lab environment presents unique requirements for data access: Its exploratory, multiplicative, and connective nature provides challenges and opportunities that have gone unexplored. Currently, these challenges make interactive educational use impractical. Also, student training requirements have been a noted problem. We present “GeoTorrent”, a system that enables such use for K-20 educational institutions. GeoTorrent provides a client-side proxy server that …

We present the transverse momentum (p_T) spectra for identified charged pions, protons and anti-protons from p+p and d+Au collisions at . The spectra are measured around midrapidity (|y|/c with particle identification from the ionization energy loss and its relativistic rise in the time projection chamber and time-of-flight in STAR. The charged pion and proton + anti-proton spectra at high p_T in p+p and d+Au collisions are in good agreement with a phenomenological model (EPOS) and with next-to-leading order perturbative quantum chromodynamic (NLO pQCD) calculations with a specific fragmentation scheme and factorization scale. We found that all proton, …

Autonomous Fish Tracking By Rov Using Monocular Camera, Jun Zhou, Christopher M. Clark

Computer Science and Software Engineering

This paper concerns the autonomous tracking of fish using a Remotely Operated Vehicle (ROV) equipped with a single camera. An efficient image processing algorithm is presented that enables pose estimation of a particular species of fish - a Large Mouth Bass. The algorithm uses a series of filters including the Gabor filter for texture, projection segmentation, and geometrical shape feature extraction to find the fishes distinctive dark lines that mark the body and tail. Feature based scaling then produces the position and orientation of the fish relative to the ROV. By implementing this algorithm on each frame of a series …

Structured Queries For Semistructured Probabilistic Data, Alex Dekhtyar, Krol Kevin Mathias, Praveen Gutti

Computer Science and Software Engineering

We present SPOQL, a structured query language for Semistructured Probabilistic Object (SPO) model [4]. The original querylanguage—SP-Algebra [4], has traditional limitations like terse functional notation and unfamiliarity to application programmers. SPOQL alleviates these problems by providing familiar SQL-like declarative syntax. We show that parsing SPOQL queries is a more involving task than parsing SQL queries. We also present an eagerevaluation algorithm for SPOQL queries

Multihierarchical Xquery For Document-Centric Xml, Ionut E. Iacob, Alex Dekhtyar

Computer Science and Software Engineering

Text has a non-hierarchical structure. Not surprisingly, searching for information in the content of a document often yields results that overlap the structure within the document. It is often of a great interest to relate such results to the embedded document structure. In this work we present an extension of the XQuery language over multihierarchical document-centric XML documents. We illustrate the benefits of using multihierarchical XQuery for text-and-structure searches in document-centric XML documents More specifically, multihierarchical XQuery allows representing relationships between textsearch results and document structure even for cases wheresuch search results overlap markup boundaries and even incases when only …

Modeling And Simulation Of The Videoray Pro Iii Underwater Vehicle, Wei Wang, Christopher M. Clark

Computer Science and Software Engineering

Accurate modeling and simulation of underwater vehicles is essential for autonomous control. In this paper, we present a dynamic model of the VideoRay Pro III microROV, in which the hydrodynamic derivatives are determined both theoretically and experimentally, based on the assumption that the motions in different directions are decoupled. The experiments show that this assumption is reasonable within operating conditions of the VideoRay Pro III. A computer simulation with 3D graphics is also developed to help user to visualize the vehicle's motion.

Lecture Notes: Non-Standard Approach To J.F. Colombeau’S Theory Of Generalized Functions, Todor D. Todorov

Mathematics

In these lecture notes we present an introduction to non-standard analysis especially written for the community of mathematicians, physicists and engineers who do research on J. F. Colombeau’ theory of new generalized functions and its applications. The main purpose of our non-standard approach to Colombeau’ theory is the improvement of the properties of the scalars of the varieties of spaces of generalized functions: in our non-standard approach the sets of scalars of the functional spaces always form algebraically closed non-archimedean Cantor complete fields. In contrast, the scalars of the functional spaces in Colombeau’s theory are rings with zero divisors. The …

On The Influence Of Test-Driven Development On Software Design, David S. Janzen, Hossein Saiedian

Computer Science and Software Engineering

Test-driven development (TDD) is an agile software development strategy that addresses both design and testing. This paper describes a controlled experiment that examines the effects of TDD on internal software design quality. The experiment was conducted with undergraduate students in a software engineering course. Students in three groups completed semester-long programming projects using either an iterative Test-First (TDD), iterative Test-Last, or linear Test-Last approach. Results from this study indicate that TDD can be an effective software design approach improving both code-centric aspects such as object decomposition, test coverage, and external quality, and developer-centric aspects including productivity and confidence. In addition, …

Physics

We report the present results of the CUORICINO experiment, a cryogenic experiment on neutrinoless Double Beta Decay (DBD) of n¹³⁰Te consisting of an array of 62 TeOn₂ crystals with a total active mass of 40.7 kg. The array is framed inside a dilution refrigerator, heavily shielded against environmental radioactivity and high-energy neutrons, and it is operated at a temperature of 8mK in the Gran Sasso Underground Laboratory. After several improvements the live time of the experiment is near 75%.

Multiscale Image Registration, Dana C. Paquin, Doron Levy, Eduard Schreibmann, Lei Xing

Mathematics

A multiscale image registration technique is presented for the registration of medical images that contain significant levels of noise. An overview of the medical image registration problem is presented, and various registration techniques are discussed. Experiments using mean squares, normalized correlation, and mutual information optimal linear registration are presented that determine the noise levels at which registration using these techniques fails. Further experiments in which classical denoising algorithms are applied prior to registration are presented, and it is shown that registration fails in this case for significantly high levels of noise, as well. The hierarchical multiscale image decomposition of E. …

Will Johnny/Joanie Make A Good Software Engineer?: Are Course Grades Showing The Whole Picture?, Jane Huffman Hayes, Alex Dekhtyar, Ashlee Holbrook, Olga Dekhtyar, Senthil Sundaram

Computer Science and Software Engineering

Predicting future success of students as software engineers is an open research area. We posit that current grading means do not capture all the information that may predict whether students will become good software engineers. We use one such piece of information, traceability of project artifacts, to illustrate our argument. Traceability has been shown to be an indicator of software project quality in industry. We present the results of a case study of a University of Waterloo graduate-level software engineering course where traceability was examined as well as course grades (such as mid-term, project grade, etc.). We found no correlation …

On Potential Validity Of Document-Centric Xml Documents, Ionut E. Iacob, Alex Dekhtyar, Michael I. Dekhtyar

Computer Science and Software Engineering

Document-centric XML document creation is a process of marking up textual content rather than typing text in a predefined structure. It turns out that, although the final document has to be valid with respect to the DTD/Schema used for the encoding, the "in-progress" document is almost never valid. At the same time, it is important to ensure that at each moment of time, the editor is working with an XML document that can be enriched with further markup to become valid. In this paper we explain the notion of potential validity of XML documents, which allows us to distinguish between …

Distinguishing Between Dirac And Majorana Neutrinos With Two-Particle Interferometry, T. Gutierrez

Physics

Two-particle interferometry, a second-order interference effect, is explored as another possible tool to distinguish between massive Dirac and Majorana neutrinos. A simple theoretical framework is discussed in the context of several gedanken experiments. The method can in principle provide both the mass scale and the quantum nature of the neutrino for a certain class of incoherent left-handed source currents.

Hydrodynamics Of Polar Liquid Crystals, William Kung, Cristina M. Marchetti, Karl Saunders

Physics

Starting from a microscopic definition of an alignment vector proportional to the polarization, we discuss the hydrodynamics of polar liquid crystals with local C_∞v symmetry. The free energy for polar liquid crystals differs from that of nematic liquid crystals (D_∞h) in that it contains terms violating the n→−n symmetry. First we show that these Z₂-odd terms induce a general splay instability of a uniform polarized state in a range of parameters. Next we use the general Poisson-bracket formalism to derive the hydrodynamic equations of the system in the polarized state. The structure of …

Reduction Of Potential Fire Behavior In Wildland-Urban Interface Communities In Southern California: A Collaborative Approach, Christopher Dicus, Michael E. Scott

Natural Resources Management and Environmental Sciences

This manuscript details a collaborative effort that reduced the risk of wildfire in an affluent, wildland-urban interface community in southern California while simultaneously minimizing the environmental impact to the site. FARSITE simulations illustrated the potential threat to the community of Rancho Santa Fe in San Diego County, California, where multimillion-dollar homes were located immediately above a designated open space area that consisted primarily of 60-year-old, decadent chaparral. Post-treatment fire behavior simulations demonstrated the potential ability to moderate fire behavior. Results of the fire behavior modeling led to a recognition for the need for fuels treatments by both homeowners and regulatory …
