title: Variable Speed Limit Control at Sag Curves Through Connected Vehicles: Implications of Alternative Communications and Sensing Technologies
Creators: name: Nezafat, Reza Vatani
Publisher: name: Old Dominion University Libraries
Year: 2019

description: Connected vehicles (CVs) will enable new applications to improve traffic flow. This study’s focus is to investigate how potential implementation of variable speed limit (VSL) through different types of communication and sensing technologies on CVs may improve traffic flow at a sag curve. At sag curves, the gradient changes from negative to positive values which causes a reduction in the roadway capacity and congestion. A VSL algorithm is developed and implemented in a simulation environment for controlling the inflow of vehicles to a sag curve on a freeway to minimize delays and increase throughput. Both vehicle-to-vehicle (V2V) and infrastructure-to-vehicle (I2V) options for CVs are investigated while implementing the VSL control strategy in a simulation environment. Through a feedback control algorithm, the speed of CVs are manipulated in the upstream of the sag curve to avoid the formation of bottlenecks caused by the change in longitudinal driver behavior. A modified version of the intelligent driver model (IDM) is used to simulate driving behavior on the sag curve. Depending on the traffic density at a sag curve, the feedback control algorithm adjusts the approach speeds of CVs so that the throughput of the sag curve is maximized. A meta-heuristic algorithm is employed to determine the critical control parameters. Various market penetration rates for CVs are considered in the simulations for three alternative communications and sensing technologies. It is demonstrated that for higher Market Penetration Rates (MPR) the performance is the same for all three scenarios which means there is no need for infrastructure-based sensing when the MPR is high enough. The results demonstrate that not only the MPR of CVs but also how CVs are distributed in the traffic stream is critical for system performance. While MPR could be high, uneven distribution of CVs and lack of CVs at the critical time periods as congestion is building up may cause a deterioration in system performance.
title: Determining the Validity of a New Cycle Ergometer Protocol for Estimating VO(2)Max
Creators: name: Parrott, James Allen
Publisher: name: Old Dominion University Libraries
Year: 2003

description: The current American College of Sports Medicine (ACSM) submaximal cycle ergometer protocol has been evaluated by several researchers for its validity in estimating maximal oxygen consumption (VO2max). It has been found that the ACSM protocol overestimates VO2max by 28% on average (Swain and Wright, 1997). It is felt that the short stage duration, only 3 minutes, of the ACSM protocol is largely responsible for this overestimation. The new submaximal cycle ergometer protocol evaluated here utilizes a 6-minute stage in an attempt to reduce the overestimation of VO2max while increasing the overall test validity.

A regression performed on actual VO2max vs. the VO2 Reserve method of VO2max estimation showed an r-value of 0.89, and an SEE of 3.97 ml·min−1.kg−1. The mean value of actual VO2max was 36.9 ± 8.8 ml·min−1. kg−1, while that for the VO2R estimated VO2max was 36.7 ± 8.4 ml·min−1.kg −1. A regression performed on actual VO2max vs. the Astrand estimate of VO2max showed an r-value of 0.82, and an SEE of 5.09 ml·min−1.kg−1. The mean value for the Astrand estimate of VO2max was 39.8 ± 11.1 ml·min−1.kg−1.

description: One of the most important criteria in the design of fixed offshore wind turbine structures is fatigue resistance. There is an unabated need for research in order to improve and optimize current design methods. There are mainly two approaches for structural analysis available in the offshore industry: the Integrated Design Approach (IDA) and the Sequential Design Approach (SDA). Within the IDA, the entire wind turbine, consisting of the jacket structure including tower and the rotor nacelle assembly (RNA), is considered as a unique system exposed to wind- and wave-induced loads in an aero-hydro-elastic solver. In SDA, the jacket structure is converted into a superelement and implemented into an aero-elastic solver, where it is expanded by an RNA in order to obtain the wind-induced interface loads. The obtained interface loads are used for further analysis in a more advanced offshore code, where the wave-induced loads are simulated. The fatigue damage of the relevant K-joint in the support structure is afterwards compared to the one obtained in terms of IDA. Apart from the judgement about advantages and disadvantages of both approaches, this work benefits from confirming the reliability and applicability of both approaches.
Simulating all non-signalling correlations via classical or quantum theory with negative probabilities

description: Many-party correlations between measurement outcomes in general probabilistic theories are given by conditional probability distributions obeying the non-signalling condition. We show that any such distribution can be obtained from classical or quantum theory, by relaxing positivity constraints on either the mixed state shared by the parties, or the local functions which generate measurement outcomes. Our results apply to generic non-signalling correlations, but in particular they yield two distinct quasi-classical models for quantum correlations.

description: This paper presents a new approach to estimate the benefit of a energy storage for certain robots. This method can be used directly in the planning phase of production. First, a robot model is developed including the DC grid coupling of the individual drives. This model is validated by several measurements of the absorbed power, brake power and DC grid voltage in a real car body shop. In a next step, the model is used to estimate the potential of an energy storage system for robots in a specific production. The e stimation was successfully validated with and without energy storage. In the experimental evaluation an energy saving of 10% was achieved.
title: The Effect of Three Foot Orthoses on Plantar Pressure Under the First Metatarsophalangeal Joint of Pes Planus Foot Type During Standing and Slow Running
Creators: name: Nordsiden, Lacey Ann
Publisher: name: Old Dominion University Libraries
Year: 2007

description: The purpose of this study was to examine the effect of three different foot orthoses on plantar pressure under the first metatarsophalangeal joint during standing and slow running. Twenty physically active participants, 12 males (19.7±1.3 years, 181.5±6.3cm, 83.6±12.3kg) and 8 females (20.8±1.5 years, 172.7±11.2cm, 69.9±14.2kg) with navicular drop greater than 10mm, no history of surgery to the lower extremity, and no history of pain or injury to the 1st metatarsophalangeal joint in the past six months volunteered for the study. Each subject performed standing and slow running tasks with four different orthosis conditions: no orthosis, metatarsal dome, U-shaped orthosis, and donut-shaped orthosis. The Pedar in-shoe pressure measurement system was used to examine the effects of each orthosis peak and mean pressure under four areas of the foot: rearfoot, lateral forefoot, medial forefoot, and the first metatarsophalangeal joint. Data were collected using Pedar-X Expert software and exported into an Excel spreadsheet for analysis. Separate 2X4X4 repeated measures ANOVAs were used to analyze peak plantar pressure and mean plantar pressure. The metatarsal dome significantly decreased peak running pressure compared to no orthosis and the donut-shaped orthosis, as well as mean standing and running pressure compared to all orthosis conditions. The U-shaped orthosis significantly reduced mean running pressure compared to no orthosis. The donut-shaped orthosis significantly increased peak and mean standing pressure compared to all orthosis conditions; it similarly significantly increased peak and mean running pressure compared to the metatarsal dome and U-shaped orthosis. Findings suggest that the metatarsal dome is most effective in reducing both peak and mean plantar pressure during standing and slow running. Further research is needed to examine the application of these results to other foot types as well as symptomatic individuals.

description: Abstract

This research is motivated by the condition that so far the government has only relied on the role of a land regulator. While other roles are not carried out by the government, namely the role of land availability regulator (land manager). By holding a land bank, at least it can answer various complex problems related to the provision of land for development purposes. This study aims to discuss the essence of the existence of a land bank in the provision of land, the regulation and implementation of land banks in the provision of land, and the construction of land banks for the interests of the state in the future. This research is a type of normative legal research or doctrinal research that is analyzed by argumentum per analogium. The results of this study indicate that the essence of the existence of a land bank in the provision of land for the interests of the state is very important, considering that land is an important commodity for human life. Regulation and implementation of land banks can be a powerful tool in providing land for the interests of the state. So that clear laws and regulations are needed regarding the establishment and operation of land banks. The construction of a Land Bank for the interests of the state in the future requires a comprehensive and planned approach, by conducting a thorough analysis of land needs for the interests of the state in the future. The suggestion that the author can give from this research is that it is hoped that in the future, the existence of a land bank will overcome various problems that arise related to the need for land for the purposes of infrastructure development, housing and development for social interests.

description: We show how the recently developed theory of geodesic transport barriers for fluid flows can be used to uncover key invariant manifolds in externally forced, one-degree-of-freedom mechanical systems. Specifically, invariant sets in such systems turn out to be shadowed by least-stretching geodesics of the Cauchy-Green strain tensor computed from the flow map of the forced mechanical system. This approach enables the finite-time visualization of generalized stable and unstable manifolds, attractors and generalized KAM curves under arbitrary forcing, when Poincare maps are not available. We illustrate these results by detailed visualizations of the key finite-time invariant sets of conservatively and dissipatively forced Duffing oscillators.

description: This is a textbook, in Spanish, for an introductory short course that focusses on the ergodic properties of topological and statistical attractors. It is directed to graduate students in Mathematics and related Science, in particular to the students-participants of the XXVI Escuela Venezolana de Matemática. The first three chapters include a review of the basic concepts and properties of the ergodic theory and of the topological and differentiable dynamics of systems that evolve on discrete time. They do not require from the reader previous knowledge on Dynamical Systems. The latter three chapters develop the theory of topological attractors, SRB measures, and the existence of Gibbs and physical measures for hyperbolic and sufficiently differentiable systems. Finally, for continuous and non necessarily differentiable systems, we include a review of Milnor's and Ilyashenko's or statistical attractors, the proof of their existence and the relation between statistical attractors and the "SRB-like" or pseudo-physical measures.

description: Polarization maintaining single-mode optical fibers are key components in the interferometry of the Laser Interferometer Space Antenna (LISA). LISA's measurement principle relies on the availability of space qualified fibers of this type which influence the phase of light with a wavelength of 1064 nm passing in opposite directions through them with differences smaller than 6 prad/. We present a measurement scheme suitable to sense these non-reciprocal phase changes, as well as results obtained using this setup on samples of commercially available fibers. The experimental setup for the fiber characterization consists of a quasi-monolithic interferometer which constitutes a representative cut-out of the local interferometry on-board LISA concerning the fiber. Several noise sources are identified and improvements to the setup are presented to overcome them. The noise level achieved using this setup is between approximately 40 prad/ and 400 prad/ in the frequency range between 1 mHz and 1 Hz. It is also verified that this noise level is limited by the setup and not introduced by the fiber.

description: We propose a new formulation of the statistical multifragmentation model based on the analysis of the virial expansion for a system of the nuclear fragments of all sizes. The developed model not only enables us to account for short-range repulsion, but also to calculate the surface free energy which is induced by the interaction between the fragments. We propose a new parameterization for the liquid phase pressure which allows us to introduce a compressible nuclear liquid into the statistical multifragmentation model. The resulting model is exactly solvable and has no irregular behavior of the isotherms in the mixed phase region that is typical for mean-field models. The general conditions for the 1-st and 2-nd (or higher) order phase transitions are formulated. It is shown that all endpoints of the present model phase diagram are the tricritical points, if the Fisher exponent $τ$ is in the range $\{3}{2} \le τ\le 2$. The treatment of nuclear liquid compressibility allows us to reduce the tricritical endpoint density of the statistical multifragmentation model to one third of the normal nuclear density. A specific attention is paid to of the fragment size distributions in the region of a negative surface tension at supercritical temperatures.

description: This paper reports on an all-sky search for periodic gravitational waves from sources such as deformed isolated rapidly spinning neutron stars. The analysis uses 840 hours of data from 66 days of the fifth LIGO science run (S5). The data were searched for quasimonochromatic waves with frequencies f in the range from 50 to 1500 Hz, with a linear frequency drift ˙f (measured at the solar system barycenter) in the range −f/τ<˙f<0.1f/τ, for a minimum spin-down age τ of 1000 years for signals below 400 Hz and 8000 years above 400 Hz. The main computational work of the search was distributed over approximately 100 000 computers volunteered by the general public. This large computing power allowed the use of a relatively long coherent integration time of 30 hours while searching a large parameter space. This search extends Einstein@Home’s previous search in LIGO S4 data to about 3 times better sensitivity. No statistically significant signals were found. In the 125–225 Hz band, more than 90% of sources with dimensionless gravitational-wave strain tensor amplitude greater than 3×10−24 would have been detected.

description: The dark matter directional detection opens a new field in cosmology bringing the possibility to build a map of nuclear recoils that would be able to explore the galactic dark matter halo giving access to a particle characterization of such matter and the shape of the halo. The MIMAC (MIcro-tpc MAtrix of Chambers) collaboration has developed in the last years an original prototype detector based on the direct coupling of large pixelized micromegas with a devoted fast self-triggered electronics showing the feasibility of a new generation of directional detectors. The discovery potential of this search strategy is discussed and illustrated. In June 2012, the first bi-chamber prototype has been installed at Modane Underground Laboratory (LSM) and the first underground background events, the gain stability and calibration are shown.

description: This paper provides an overview on the most relevant legal, ethical and social implications arising from the use of computational intelligence based systems for land border crossings. Based on the automatic deception detection system (ADDS) developed in the iBorderCtrl project, issues such as the peculiarities of the interaction of humans with machines, profiling, automated decision-making and the risk of false positives can be identified and demonstrate how computational intelligence based systems can challenge fundamental legal and ethical principles. These include in particular the right to privacy, human dignity and the principle of non-discrimination. By further analysing the various issues, this paper seeks to provide some thoughts on remedies and safeguards which should be considered when developing computational intelligence based systems.© 2018 IEEE.

description: We present a comprehensive X-ray point source catalog of NGC 404 obtained as part of the Chandra Local Volume Survey. A new, 97 ks Chandra ACIS-S observation of NGC 404 was combined with archival observations for a total exposure of ~123 ks. Our survey yields 74 highly significant X-ray point sources and is sensitive to a limiting unabsorbed luminosity of ~6x10^35 erg s^-1 in the 0.35-8 keV band. To constrain the nature of each X-ray source, cross-correlations with multi-wavelength data were generated. We searched overlapping HST observations for optical counterparts to our X-ray detections, but find only two X-ray sources with candidate optical counterparts. We find 21 likely low mass X-ray binaries (LMXBs), although this number is a lower limit due to the difficulties in separating LMXBs from background AGN. The X-ray luminosity functions (XLFs) in both the soft and hard energy bands are presented. The XLFs in the soft band (0.5-2 keV) and the hard band (2-8 keV) have a limiting luminosity at the 90% completeness limit of 10^35 erg s^-1 and 10^36 erg s^-1, respectively, significantly lower than previous X-ray studies of NGC 404. We find the XLFs to be consistent with those of other X-ray populations dominated by LMXBs. However, the number of luminous (>10^37 erg s^-1) X-ray sources per unit stellar mass in NGC 404 is lower than is observed for other galaxies. The relative lack of luminous XRBs may be due to a population of LMXBs with main sequence companions formed during an epoch of elevated star formation ~0.5 Gyr ago.

description: Objects sensed by laser interferometers are usually not stable in position or orientation. This angular instability can lead to a coupling of angular tilt to apparent longitudinal displacement - tilt-to-length coupling (TTL). In LISA this is a potential noise source for both the test mass interferometer and the long-arm interferometer. We have experimentally investigated TTL coupling in a setup representative for the LISA test mass interferometer and used this system to characterise two different imaging systems (a two-lens design and a four-lens design) both designed to minimise TTL coupling. We show that both imaging systems meet the LISA requirement of ±25 μm rad-1 for interfering beams with relative angles of up to ±300 μrad. Furthermore, we found a dependency of the TTL coupling on beam properties such as the waist size and location, which we characterised both theoretically and experimentally. © 2018 IOP Publishing Ltd.

description: We present the results of a comparative period search on different time-scales and modelling of the ZZ Ceti (DAV) star GD 154. We determined six frequencies as normal modes and four rotational doublets around the ones having the largest amplitude. Two normal modes at 807.62 and 861.56 microHz have never been reported before. A rigorous test revealed remarkable intrinsic amplitude variability of frequencies at 839.14 and 861.56 microHz over a 50 d time-scale. In addition, the multimode pulsation changed to monoperiodic pulsation with an 843.15 microHz dominant frequency at the end of the observing run. The 2.76 microHz average rotational split detected led to a determination of a 2.1 d rotational period for GD 154. We searched for model solutions with effective temperatures and log g close to the spectroscopically determined ones. The best-fitting models resulting from the grid search have M_H between 6.3 x 10^-5 and 6.3 x 10^-7 M*, which means thicker hydrogen layer than the previous studies suggested. Our investigations show that mode trapping does not necessarily operate in all of the observed modes and the best candidate for a trapped mode is at 2484 microHz.

description: Based on an extension of the fiber bundle model we investigate numerically the motion of the crack front through a weak plane separating a soft and an infinitely stiff block. We find that there are two regimes. At large scales the motion is consistent with the pinned elastic line model and we find a roughness exponent equal to 0.39 +/- 0.04 characterizing it. At smaller scales, coalescence of holes dominates the motion rather than pinning of the crack front. We find a roughness exponent consistent with 2/3, which is the gradient percolation value. The length of the crack front is fractal on these smaller scales. We determine its fractal dimension to be 1.77 +/- 0.02, consistent with the hull of percolation clusters, 7/4. This suggests that the crack front is described by two universality classes: on large scales, the pinned elastic line one and on small scales, the percolation universality class.

description: We report the suitability of an Einstein-Podolsky-Rosen entanglement source for Gaussian continuous-variable quantum key distribution at 1550 nm. Our source is based on a single continuous-wave squeezed vacuum mode combined with a vacuum mode at a balanced beam splitter. Extending a recent security proof, we characterize the source by quantifying the extractable length of a composable secure key from a finite number of samples under the assumption of collective attacks. We show that distances in the order of 10 km are achievable with this source for a reasonable sample size despite the fact that the entanglement was generated including a vacuum mode. Our security analysis applies to all states having an asymmetry in the field quadrature variances, including those generated by superposition of two squeezed modes with different squeezing strengths.
title: Comparison of Support Methods for Static Aerodynamic Testing and Validation of a Magnetic Suspension and Balance System

description: Magnetic suspension wind tunnels offer an alternative to traditional physical support methods. They allow for the collection of support interference free data and broader dynamic test capabilities than existing methods. Determination of dynamic aerodynamic characteristics is a crucial portion of the design of new re-entry capsules. A NASA initiative restored the 6-inch Magnetic Suspension and Balance System to support the design of a new MSBS for a supersonic wind tunnel. Before a new MSBS can be constructed, the characteristics of the current MSBS must be examined.

This thesis discusses the calibration and validation of the 6-inch MSBS. After calibration, three aerodynamic tests were performed in order to characterize the data collected from the MSBS. They included a traditional sting supported test, a free-flying magnetically suspended test, and a magnetically suspended test with aerodynamic interference from a dummy sting. The ideology behind the chosen experimental design was to isolate the effect of support interference from any MSBS calibration errors. Any differences between the sting supported and the dummy sting tests would be caused by the MSBS. Any differences between the free-flying and the dummy sting tests would be due to support interference. Multiple components were designed and constructed, in order to support this effort.

The goals of this thesis were met. The MSBS data had high repeatability and accuracy, which validated the force recovery method. Aerodynamic testing showed in minimal variation

between support methods at low angles of attack. Discrepancies between support methods increased with models mounted at high angles of attack. Current references generally exhibit much higher Reynolds numbers than the MSBS and the wind tunnel can achieve. Support interference free reference data in an achievable Reynolds number was generated for future NASA testing. While the outcome was successful, multiple possible improvements or future projects were identified that can be completed prior to design and construction of the new MSBS.

description: In order to implement optical inter-spacecraft ranging and data transfer for LISA, the carrier of the laser link must be phase modulated with pseudo-randon noise sidebands. The data acquisition and delay estimation are then implemented in the phasemeter as back end processing. This work presents a proposed demodulation scheme with submeter ranging accuracy and several kilobytes data rate. Its functionality is demonstrated both in a software simulation and in a FPGA-based hardware implementation.
title: The Influence of Color on the Teaching of Juggling to Elementary School Children

description: Learning to juggle is difficult for elementary school students; it involves eye-hand coordination and complex movement patterns. Recognizing and using color for figure- and-ground visual perception is a necessary skill for tracking moving objects to catch them effectively. Can juggling instruction be influenced by the color of the juggling object used? Is one color more effective than another or does a combination of three different colors provide the most effective equipment choice?

Children in third, fourth, and fifth grade physical education classes were randomly assigned to color choices for juggling objects in a month-long unit of juggling instruction. The choices, all white, all brown, all blue, and a combination of white, brown, and blue, were used by each designated class consistently for the instruction, practice and assessment lessons. Other variables included age, grade, and gender of the children.

Each juggling lesson lasted between 10-12 minutes and instruction given was identical regardless of object color. The final assessment of juggling was done by counting the total number of consecutive catches achieved over three trials. No significant differences were noted due to grade or gender. Significant color differences were noted, with all white having the lowest mean for total catches, which was significantly different from the other three color choices. The means for mixed colors and all brown were slightly less than the mean for all although those differences were not statistically significant. Since the upper portions of the gymnasium walls are white, it was concluded that those objects that did not blend with the wall color were more effective in allowing consecutive catching.

description: The goal of developing a firmer theoretical understanding of inhomogenous temporal processes -- in particular, the waiting times in some collective dynamical system -- is attracting significant interest among physicists. Quantifying the deviations in the waiting-time distribution away from one generated by a random process, may help unravel the feedback mechanisms that drive the underlying dynamics. We analyze the waiting-time distributions of high frequency foreign exchange data for the best executable bid-ask prices across all major currencies. We find that the lognormal distribution yields a good overall fit for the waiting-time distribution between currency rate changes if both short and long waiting times are included. If we restrict our study to long waiting-times, each currency pair's distribution is consistent with a power law tail with exponent near to 3.5. However for short waiting times, the overall distribution resembles one generated by an archetypal complex systems model in which boundedly rational agents compete for limited resources. Our findings suggest a gradual transition arises in trading behavior between a fast regime in which traders act in a boundedly rational way, and a slower one in which traders' decisions are driven by generic feedback mechanisms across multiple timescales and hence produce similar power-law tails irrespective of currency type.

description: Fahrkartenautomaten und Kunden – eine Geschichte voller Missverständnisse. Wie oft ist es Ihnen schon so ergangen, dass Sie an einem Automaten ein Ticket kaufen wollten und entweder gar nicht zum Ziel kamen oder nach langem Hin und Her immer noch nicht so recht sicher waren, das richtige Ticket erhalten zu haben. Genau das wollten wir ändern. Unser Ziel war es, Kunden das Gefühl zu vermitteln, vom Automaten verstanden zu werden, und nicht Verständnis für die Eigenheiten des Automaten aufbringen zu müssen. Der vorliegende Beitrag stellt am Beispiel der Entwicklung des Bediendialoges für die stationären Fahrkartenautomaten der Münchner Verkehrsgesellschaft (MVG) vor, wie eine nutzerzentrierte Entwicklung der Bedienabläufe an einem digitalen Kommunikationsinstrument wie einem Ticketautomaten funktionieren kann.

description: We present low-temperature transport experiments on Aharonov-Bohm (AB) rings fabricated from two-dimensional hole gases in p-type GaAs/AlGaAs heterostructures. Highly visible h/e (up to 15%) and h/2e oscillations, present for different gate voltages, prove the high quality of the fabricated devices. Like in previous work, a clear beating pattern of the h/e and h/2e oscillations is present in the magnetoresistance, producing split peaks in the Fourier spectrum. The magnetoresistance evolution is presented and discussed as a function of temperature and gate voltage. It is found that sample specific properties have a pronounced influence on the observed behavior. For example, the interference of different transverse modes or the interplay between h/e oscillations and conductance fluctuations can produce the features mentioned above. In previous work they have occasionally been interpreted as signatures of spin-orbit interaction (SOI)-induced effects. In the light of these results, the unambiguous identification of SOI-induced phase effects in AB rings remains still an open and challenging experimental task.
