Cpd -20 1123 (Albus 1) Is A Bright He-B Subdwarf, Stéphane Vennes, Adéla Kawka, Jonathan Allyn Smith

Aerospace, Physics, and Space Science Faculty Publications

Based on photometric and astrometric data it has been proposed that Albus 1 (also known as CPD -20 1123) might be a hot white dwarf similar to G191-B2B or, alternatively, a hot subdwarf. We obtained a series of optical spectra showing that CPD -20 1123 is a bright He-B subdwarf. We analyzed the H i Balmer and He i line spectra and measured Tcff = 19,800 ± 400 K, and. Thislogg p 4.55 ± 0.10 and log N(He)/N(H) p 0.15 ± 0.15 This peculiar object belongs to a family of evolved helium-rich stars that may be the products of double-degenerate …

Asymmetric Weak-Pinning Superconducting Channels: Vortex Ratchets, Britton Plourde, T. W. Heitmann, C. Song, M. P. Defeo, Kang Yu

Physics - All Scholarship

The controlled motion of objects through narrow channels is important in many fields. We have fabricated asymmetric weak-pinning channels in a superconducting thin-film strip for controlling the dynamics of vortices. The lack of pinning allows the vortices to move through the channels with the dominant interaction determined by the shape of the channel walls. We present measurements of vortex dynamics in the channels and compare these with similar measurements on a set of uniform-width channels. While the uniform-width channels exhibit a symmetric response for both directions through the channel, the vortex motion through the asymmetric channels is quite different, with …

A Two-Phase Approach To Interactivity Enhancement For Large-Scale Distributed Virtual Environments, Nguyen Binh Duong Ta, Suiping Zhou

Research Collection School Of Computing and Information Systems

Distributed virtual environments (DVEs) are distributed systems that allow multiple geographically distributed clients (users) to interact simultaneously in a computer-generated, shared virtual world. Applications of DVEs can be seen in many areas nowadays, such as online games, military simulations, collaborative designs, etc. To support large-scale DVEs with real-time interactions among thousands or even more distributed clients, a geographically distributed server architecture (GDSA) is generally needed, and the virtual world can be partitioned into many distinct zones to distribute the load among the servers. Due to the geographic distributions of clients and servers in such architectures, it is essential to efficiently …

Spilling: Expanding Hand Held Interaction To Touch Table Displays, Jeffrey Clement, Dan R. Olsen Jr., Aaron Pace

Faculty Publications

We envision a nomadic model of interaction where the personal computer fits in your pocket. Such a computer is extremely limited in screen space. A technique is described for “spilling” the display of a hand held computer onto a much larger table top display surface. Because our model of nomadic computing frequently involves the use of untrusted display services we restrict interactive input to the hand held. Navigation techniques such as scrolling or turning the display can be expressed through the table top. The orientation and position of the hand held on the table top is detected using three conductive …

Do Herbivores Associate Flavors With Specific Consequences In Flavor Aversion Learning?, Bruce A. Kimball, Vida Billings

United States Department of Agriculture Wildlife Services: Staff Publications

Goats were first offered a novel, maple-flavored diet paired with either lithium chloride (LiCl) or oxalic acid (OA) delivered intraruminally. Aversion to maple diet persisted for 6 days, regardless of toxin. Following a 10-day intermission, aversion to maple diet was reacquired (spontaneous recovery) among subjects previously dosed with LiCl but not for subjects receiving OA. All subjects were then offered two diets: the maple diet previously paired with LiCl or OA and a novel grape-flavored diet. Immediately following consumption of both diets, all subjects were dosed with LiCl. Preference for maple and grape diets was assessed by two-choice test. Goats …

Determination Of Sulfadimethoxine Residues In Skunk Serum By Hplc, Thomas M. Primus, Susan M. Jojola, Stacie J. Robinson, John J. Johnston

United States Department of Agriculture Wildlife Services: Staff Publications

Sulfadimethoxine (SDM) was extracted from skunk serum and isolated by reversed-phase high performance liquid chromatography. SDM was detected by ultra-violet absorbance at 270 nm and quantified by comparison to an external calibration standard. Recovery data were determined by analyzing SDM fortified control serum. The overall mean recovery with relative standard deviations of SDM in fortified skunk serum samples was 99±7%. The recovery for 0.38, 5.2, and 14.2 μg/mL SDM was 96.0±7.5%, 102±6.1%, and 97.3±5.1%, respectively. The method limit of detection for SDM in skunk serum ranged from 0.032 to 0.057 μg/mL SDM with a mean value of 0.040 mg/mL SDM. …

Module 3 - Formal Reasoning Patterns: Introduction

Module 3: Formal Reasoning Patterns

In Piaget's theory, concrete operational reasoning is characterized by patterns of serial ordering, simple classification, conservation reasoning, and other operations applied to objects that a person is able to observe or manipulate directly. Formal reasoning patterns include these operations but go beyond them to utilize other processes in situations where one does not deal with tangible objects. Formal patterns often involve proportional reasoning, separation of variables, and combinatorial reasoning.

The film "Formal Reasoning Patterns" Davidson Films, 1976) will enable you to watch two interviews (Dr. Karplus and Dr. Peterson) working with several secondary school students who exhibit concrete or formal …

Implementation Of Uncertainty Propagation In Triton/Keno: To Support The Global Nuclear Energy Partnership, Charlotta Sanders, Denis Beller

Reactor Campaign (TRP)

Monte Carlo methods are beginning to be used for three-dimensional fuel depletion analyses to compute various quantities of interest, including isotopic compositions of used fuel.1 The TRITON control module, available in the SCALE 5.1 code system, can perform three dimensional (3-D) depletion calculations using either the KENO V.a or KENO-VI Monte Carlo transport codes, as well as the two-dimensional (2- D) NEWT discrete ordinates code. For typical reactor systems, the neutron flux is not spatially uniform. For Monte Carlo simulations, this results in non-uniform statistical uncertainties in the computed reaction rates. For spatial regions where the flux is low, e.g., …

Monaco/Mavric Evaluation For Facility Shielding And Dose Rate Analysis: To Support The Global Nuclear Energy Partnership, Charlotta Sanders, Denis Beller

Reactor Campaign (TRP)

Monte Carlo methods are used to compute fluxes or dose rates over large areas using mesh tallies. For problems that demand that the uncertainty in each mesh cell be less than some set maximum, computation time is controlled by the cell with the largest uncertainty. This issue becomes quite troublesome in deep-penetration problems, and advanced variance reduction techniques are required to obtain reasonable uncertainties over large areas.

In this project the MAVRIC sequence will be evaluated along with the Monte Carlo engine Monaco to investigate its effectiveness and usefulness in facility shielding and dose rate analyses. A previously MCNP-evaluated cask …

Exact Filtered Back Projection (Fbp) Algorithm For Spiral Computer Tomography With Variable Pitch [Us], Alexander Katsevich

UCF Patents

Reconstructing images of objects spirally scanned with two-dimensional detectors with a novel algorithm under a variable pitch (nonconstant speed), where the object is not restricted to moving at a constant velocity. The object can move at variable speeds(increasing, decreasing, combinations thereof) during the scan of the object. The image reconstruction process is proven to create an exact image of the object under the ideal circumstances. The algorithm can have a convolution-based FBP (Filtered Back Projection) structure and works very efficiently. The algorithm uses less computer power and combines the benefits of Exact Algorithms and Approximate algorithms. An object can be …

Far-Off-Resonant Ring Trap Near The Ends Of Optical Fibers, Frank Moscatelli, C. Sackett, S. Du, E. Oh

Physics & Astronomy Faculty Works

We propose that micrometer-sized atom traps can be created using the optical dipole force between the ends of two single-mode optical fibers carrying counterpropagating light beams of two different wavelengths from both fibers. The traps have a simple design that is feasible to implement with commercially available products. They can be used as a flexible “atom tweezer” to manipulate atoms in free space without the need for traditional focused laser beams. A particularly interesting feature is the formation of a static ring-shaped trap for properly chosen beam parameters. Furthermore, this ring can be split into two longitudinally adjacent rings. Microscopic …
