title: A Framework for Test & Evaluation of Autonomous Systems Along the Virtuality-Reality Spectrum
Creators: name: Gonda, Nathan D.
Publisher: name: Old Dominion University Libraries
Year: 2019

description: Test & Evaluation of autonomous vehicles presents a challenge as the vehicles may have emergent behavior and it is frequently difficult to ascertain the reason for software decisions. Current Test & Evaluation approaches for autonomous systems place the vehicles in various operating scenarios to observe their behavior. However, this introduces dependencies between design and development lifecycle of the autonomous software and physical vehicle hardware. Simulation-based testing can alleviate the necessity to have physical hardware; however, it can be costly when transitioning the autonomous software to and from a simulation testing environment. The objective of this thesis is to develop a reusable framework for testing autonomous software such that testing can be conducted at various levels of mixed reality provided the framework components are sufficient to support data required by the autonomous software. The paper describes the design of the software framework and explores its application through use cases.

description: Spontaneous fission and alpha decay are the main decay modes for superheavy nuclei. The superheavy nuclei which have small alpha decay half-life compared to spontaneous fission half-life will survive fission and can be detected in the laboratory through alpha decay. We have studied the alpha decay half-life and spontaneous half-life of some superheavy elements in the atomic range Z = 100-130. Spontaneous fission half-lives of superheavy nuclei have been calculated using the phenomenological formula and the alpha decay half-lives using Viola-Seaborg-Sobiczewski formula (Sobiczewski et al. 1989), semi empirical relation of Brown (1992) and formula based on generalized liquid drop model proposed by Dasgupta-Schubert and Reyes (2007). The results are reported here.

description: We present YJHK photometry, or a subset, for the six Y dwarfs discovered in WISE data by Cushing et al.. The data were obtained using NIRI on the Gemini North telescope. We also present a far-red spectrum obtained using GMOS-North for WISEPC J205628.90+145953.3. We compare the data to Morley et al. (2012) models, which include cloud decks of sulfide and chloride condensates. We find that the models with these previously neglected clouds can reproduce the energy distributions of T9 to Y0 dwarfs quite well, other than near 5um where the models are too bright. This is thought to be because the models do not include departures from chemical equilibrium caused by vertical mixing, which would enhance the abundance of CO, decreasing the flux at 5um. Vertical mixing also decreases the abundance of NH_3, which would otherwise have strong absorption features at 1.03um and 1.52um that are not seen in the Y0 WISEPC J205628.90+145953.3. We find that the five Y0 to Y0.5 dwarfs have 300 < T_eff K < 450, 4.0 < log g < 4.5 and f_sed ~ 3. These temperatures and gravities imply a mass range of 5 - 15 M_Jupiter and ages around 5 Gyr. We suggest that WISEP J182831.08+265037.8 is a binary system, as this better explains its luminosity and color. We find that the data can be made consistent with observed trends, and generally consistent with the models, if the system is composed of a T_eff = 325 K and log g ~ 4.0 secondary, corresponding to masses of 10 and 7 M_Jupiter and an age around 2 Gyr. If our deconvolution is correct, then the T_eff = 300 K cloud-free model fluxes at K and W2 are too faint by 0.5 - 1.0 magnitudes. We will address this discrepancy in our next generation of models, which will incorporate water clouds and mixing.

description: Deforestation is a wide-reaching problem, responsible for serious environmental issues, such as biodiversity loss and global climate change. Containing approximately ten percent of all biomass on the planet and home to one tenth of the known species, the Amazon biome has faced important deforestation pressure in the last decades. Devising efficient deforestation detection methods is, therefore, key to combat illegal deforestation and to aid in the conception of public policies directed to promote sustainable development in the Amazon. In this work, we implement and evaluate a deforestation detection approach which is based on a Fully Convolutional, Deep Learning (DL) model: the DeepLabv3+. We compare the results obtained with the devised approach to those obtained with previously proposed DL-based methods (Early Fusion and Siamese Convolutional Network) using Landsat OLI-8 images acquired at different dates, covering a region of the Amazon forest. In order to evaluate the sensitivity of the methods to the amount of training data, we also evaluate them using varying training sample set sizes. The results show that all tested variants of the proposed method significantly outperform the other DL-based methods in terms of overall accuracy and F1-score. The gains in performance were even more substantial when limited amounts of samples were used in training the evaluated methods. © 2020 International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences - ISPRS Archives.

description: We present a new dynamical study of the black hole X-ray transient GRS1915+105 making use of near-infrared spectroscopy obtained with X-shooter at the VLT. We detect a large number of donor star absorption features across a wide range of wavelengths spanning the H and K bands. Our 24 epochs covering a baseline of over 1 year permit us to determine a new binary ephemeris including a refined orbital period of P=33.85 +/- 0.16 d. The donor star radial velocity curves deliver a significantly improved determination of the donor semi-amplitude which is both accurate (K_2=126 +/- 1 km/s) and robust against choice of donor star template and spectral features used. We furthermore constrain the donor star's rotational broadening to vsini=21 +/-4 km/s, delivering a binary mass ratio of q=0.042 +/- 0.024. If we combine these new constraints with distance and inclination estimates derived from modelling the radio emission, a black hole mass of M_BH=10.1 +/- 0.6 M_sun is inferred, paired with an evolved mass donor of M_2=0.47 +/- 0.27 M_sun. Our analysis suggests a more typical black hole mass for GRS1915+105 rather than the unusually high values derived in the pioneering dynamical study by Greiner et al. (2001). Our data demonstrate that high-resolution infrared spectroscopy of obscured accreting binaries can deliver dynamical mass determinations with a precision on par with optical studies.

description: Eine Million Elektrofahrzeuge sollen 2020 auf deutschen Straßen unterwegs sein. So lautet das Ziel der Bundesregierung. Aufgrund der derzeit noch sehr hohen Preise für Elektrofahrzeuge ist es wichtig, langfristig die Attraktivität eines solchen „Stromers“ zu erhöhen. Zukünftig gilt dabei das induktive Laden (Wireless Power Transfer, WPT) als wichtiges Werkzeug hierzu. Gegenüber konduktivem Laden wird einerseits der Umgang mit einem unhandlichen Ladekabel vermieden, andererseits ist in besonderem Maße die ungewollte Emission von magnetischen Feldern zu beachten, wodurch Gesichtspunkte der EMV und des Personenschutzes berücksichtigt werden müssen. Hier setzt der dreidimensionale Feldscanner des Fraunhofer IWES an, mit dem das emittierte magnetische Streufeld frequenzund ortsselektiv, aber auch als Funktion eines Spulenversatzes vermessen wird. Neben einer Beurteilung der Streufelder nach ICNIRP oder nach anderen Richtlinien können auch die Eigenschaften des WPT-Systems gemäß der Anwendungsregel VDE-AR-E2122-4-2 [1] und IEC 61980-1 [2] geprüft werden. Zur Erprobung des Feldscanners wurde ein im Fraunhofer IWES entwickeltes induktives Ladesystem herangezogen, welches sich zurzeit im Stadium eines Labormusters befindet. Die simultan möglichen Messungen zum Wirkungsgrad wurden bei dieser Untersuchung noch nicht durchgeführt.

description: Nuclear emulsion, a tracking detector with sub-micron position resolution, has played a successful role in the field of particle physics and the analysis speed has been substantially improved by the development of automated scanning systems. This paper describes a newly developed automated scanning system and its application to the analysis of nuclear fragments emitted almost isotropically in nuclear evaporation. This system is able to recognize tracks of nuclear fragments up to |tanθ|< 3.0 (where θ is the track angle with respect to the perpendicular to the emulsion film), while existing systems have an angular acceptance limited to |tanθ|< 0.6. The automatic scanning for such a large angle track in nuclear emulsion is the first trial. Furthermore the track recognition algorithm is performed by a powerful Graphics Processing Unit (GPU) for the first time. This GPU has a sufficient computing power to process large area scanning data with a wide angular acceptance and enough flexibility to allow the tuning of the recognition algorithm. This new system will in particular be applied in the framework of the OPERA experiment : the background in the sample of tau decay candidates due to hadronic interactions will be reduced by a better detection of the emitted nuclear fragments.

description: YouSound is a social science research project that studies symphonic music education organizations centred on the inclusion of minor migrants and refugees in Europe. We have chosen two organizations in different countries to serve as case studies: the Dream Orchestra in Sweden, and El Sistema Greece. In 2022 and 2023, we are visiting both countries, applying ethnographic methods to better grasp the complexity of interactions between multicultural human beings in these music education contexts. The first two YouSound Zines were a result of visits to the Dream Orchestra in Gothenburg, Sweden. The next two editions cover the El Sistema Greece program in Athens. The ethnographic illustrator, Beatriz Machado, and I spent a month and a half following the music education work that is being done with minor migrants, refugees and Greeks. El Sistema Greece, founded in 2016, was conceived as an artistic educational tool, contributing to the education and social inclusion of migrant youth in Greece. The program has been working intensively in several of Athens’ refugee camps, as well as in schools in some of its most multicultural neighbourhoods. Please visit their website, www.elsistema.gr, for more information. Beatriz Machado applies her illustration skills to capture some of the actions, movements, pedagogical tools and emotions occurring daily in these particular music education spheres. The illustrations are accompanied by her own words, creating a graphic diary of what was lived collectively by students, teachers, parents and administrators at El Sistema Greece. We thank them for the moments we shared and hope you enjoy discovering these drawings and thoughts!

description: We present a self-consistent model of a protoplanetary disk: 'ANDES' ('AccretioN disk with Dust Evolution and Sedimentation'). ANDES is based on a flexible and extendable modular structure that includes 1) a 1+1D frequency-dependent continuum radiative transfer module, 2) a module to calculate the chemical evolution using an extended gas-grain network with UV/X-ray-driven processes surface reactions, 3) a module to calculate the gas thermal energy balance, and 4) a 1+1D module that simulates dust grain evolution. For the first time, grain evolution and time-dependent molecular chemistry are included in a protoplanetary disk model. We find that grain growth and sedimentation of large grains to the disk midplane lead to a dust-depleted atmosphere. Consequently, dust and gas temperatures become higher in the inner disk (R < 50 AU) and lower in the outer disk (R > 50 AU), in comparison with the disk model with pristine dust. The response of disk chemical structure to the dust growth and sedimentation is twofold. First, due to higher transparency a partly UV-shielded molecular layer is shifted closer to the dense midplane. Second, the presence of big grains in the disk midplane delays the freeze-out of volatile gas-phase species such as CO there, while in adjacent upper layers the depletion is still effective. Molecular concentrations and thus column densities of many species are enhanced in the disk model with dust evolution, e.g., CO2, NH2CN, HNO, H2O, HCOOH, HCN, CO. We also show that time-dependent chemistry is important for a proper description of gas thermal balance.

description: The derivation of bright-grey box models for electric drives with coupled mechanics, such as stacker cranes, robots and linear gantries is an important step in control design but often too time-consuming for the ordinary commissioning process. It requires structure and parameter identification in repeated trial and error loops. In this paper an automated genetic programming solution is proposed that can cope with various features, including highly non-linear mechanics (friction, backlash). The generated state space representation can readily be used for stability analysis, state control, Kalman filtering, etc. This, however, requires several special rules in the genetic programming procedure and an automated integration of features into the defining state space form. Simulations are carried out with industrial data to investigate the performance and robustness.

description: Gnomee is a web knowledge base that contains Digital Solutions which can act as potential Digital Game Changers in rural areas, agriculture, and forestry. Each digital solution is classified under a set of taxonomies useful to farmers, facilitators and researchers willing to identify solutions for these areas for exploitation or further enhancement. To ensure wide acceptance and exploitation of digital tools from - but not only- the research community, it is important to re-use and exploit common solutions and services with regards to core functionalities and operations and not introduce additional options, compared to existing ones. This approach should be followed from applications that require users to create an account. The challenge, in this specific context, is to eliminate the need for asking users to create yet another account and increase the possibility of exploiting the full potential of your web application.

description: Absorbing boundaries in the mean-field approximation are investigated and applied to small systems interacting with strong laser fields. Two types of calculations are considered: (i) a variational approach with a complex absorbing potential included in the full Hamiltonian and (ii) the inclusion of a complex absorbing potential in the single-particle equations. It is elucidated that the second approach outperforms the variational approach for small grids. © 2010 The American Physical Society.

description: We examine the motions of large fragments at the head of the dust tail of active asteroid P/2010 A2. In previous work we showed that these fragments were ejected from the primary nucleus in early 2009, either following a hypervelocity impact or by rotationally induced break-up. Here, we follow their positions through a series of Hubble Space Telescope images taken during the first half of 2010. The orbital evolution of each fragment allows us to constrain its velocity relative to the main nucleus after leaving its sphere of gravitational influence. We find that the fragments constituting a prominent X-shaped tail feature were emitted in a direction opposite to the motion of the asteroid and towards the south of its orbital plane. Derived emission velocities of these primary fragments range between 0.02 and 0.3 m/s, comparable to the ~0.08 m/s gravitational escape speed from the nucleus. Their sizes are on the order of decimeters or larger. We obtain the best fits to our data with ejection velocity vectors lying in a plane that includes the nucleus. This may suggest that the cause of the disruption of P/2010 A2 is rotational break-up.

description: We extend Jordan's notion of principal angles to work for two subspaces of quaternionic space, and so have a method to analyze two orthogonal projections in M_n(A) for A the real, complex or quaternionic field (or skew field). From this we derive an algorithm to turn almost commuting projections into commuting projections that minimizes the sum of the displacements of the two projections. We quickly prove what we need using the universal real C*-algebra generated by two projections.

description: Der elektrische Antriebstrang eines Elektrofahrzeuges (EF) besteht heute typischerweise aus einer HV-Batterie, einem Inverter und einer elektrischen Maschine. Im Inverter wird dabei mit Hilfe von Leistungshalbleitern die Batteriegleichspannung in einen dreiphasigen Wechselstrom gewandelt, um die elektrische Maschine anzutreiben. Schnelle Schaltzeiten bei der Wandlung gewährleisten einen hohen Wirkungsgrad und vermeiden eine Überhitzung der Leistungshalbleiter. Aufgrund des hohen Störpotenzials dieser Schalthandlungen werden nach dem Stand der Technik geschirmte Hochvoltkabel für die Batterieund Motorkabel des elektrischen Antriebsstrangs eingesetzt. Diese Schirmung ist bei vielen Systemen notwendig, um die vom Automobilhersteller geforderten Grenzwerte für gestrahlte Störemissionen einzuhalten. Nachteile des Kabelschirms sind ein hohes Gewicht, hohe Kosten und strenge Anforderungen an die Alterung der Kabelstecker. Eine mögliche Alternative zur Schirmung ist eine aufwändige Filterung der leitungsgebundenen Störung, die zumindest Vorteile beim Gewicht und den Anforderungen an die Stecker verspricht. Dieser Beitrag beschäftigt sich damit, wie die Schirmung der Hochvoltkabel die Störströme auf den Batterieleitungen und die Störspannung an der Bordnetznachbildung beeinflusst. Dazu wird bei einen bestehenden Testaufbau untersucht, wie Gleichtakt und Gegentaktstörungen im Antriebsstrang entstehen und wie diese anhand einfacher Simulationsmodelle nachgebildet werden können. Während des Betriebs des Inverters werden für ein System mit geschirmten und für ein System mit ungeschirmten Hochvoltkabel die Störspannungen an der Bordnetznachbildung (BNN) gemessen und mittels der vorgestellten Simulationen im Frequenzbereich von 150 kHz bis 110 MHz erklärt.

description: Digitale Coffee Lecture am 12.06.2023 an der Staats- und Universitätsbibliothek Hamburg Abstract: Obwohl Mehrsprachigkeit bzw. Mehrschriftlichkeit ein konstitutiver Faktor für Forschung, Lehre, Lernen und Arbeiten in allen akademischen Einrichtungen ist, unterstützen Wissenschaftsinfrastrukturen wie (Universitäts)Bibliotheken oft hauptsächlich nur die Verwendung der englischen Sprache und lateinischen Schrift. Davon sind in besonderer Weise die Digitalen Geistes- und Sozialwissenschaften (Digital Humanities) betroffen, die international sowie auf eine Region bezogen forschen und lehren und dabei auf die Nutzung von multilingualen (Meta)Daten, multilingualen digitalen Tools (Plattformen, Software, …) bzw. insbesondere auf die Verwendung nichtlateinischer Schriften in digitalen Umgebungen angewiesen sind. Unter dem Motto "Disrupting Digital Monolingualism" (King's College 2020) arbeiten derzeit immer mehr Forschende und Bibliothekar*innen zusammen, um diese anglophone Hegemonie als Ursache für kulturelle und technologische/digitale Asymmetrien sowie als Hindernis für den globalen wissenschaftlichen Austausch im Allgemeinen zu beseitigen, z. B. die mangelnde Sichtbarkeit/Zugänglichkeit von und Zugang zu Forschung oder Quellen in nichtanglophonen Sprachen und nichtlateinischen Schriften. Die Coffee Lecture zielt darauf ab, das Bewusstsein für Fragen der Multilingualität und Forschungsinfrastrukturen zu schärfen, mit besonderem Augenmerk auf Bibliotheksservices für Digital Humanities und nicht-lateinische Schriften. Am Beispiel des "Multilingual Digital Humanities Lab" (https://www.ada.fu-berlin.de/ada-labs/multilingual-dh/index.html ) im „Ada Lovelace Center für Digital Humanities“ (ADA) an der Universitätsbibliothek der Freien Universität Berlin (FUB) werden Akteure und Netzwerke innerhalb und außerhalb der FUB vorgestellt. Auf diese Weise soll die Diskussion um Aufgaben und Rollen von Bibliotheken für die Digital Humanities allgemein mit dem Aspekt der Stärkung von sprachlicher und schriftlicher Diversität in Bibliotheken verbunden werden.

description: We study localized waves in chains of oscillators coupled by Hertzian interactions and trapped in local potentials. This problem is originally motivated by Newton's cradle, a mechanical system consisting of a chain of touching beads subject to gravity and attached to inelastic strings. We consider an unusual setting with local oscillations and collisions acting on similar time scales, a situation corresponding e.g. to a modified Newton's cradle with beads mounted on stiff cantilevers. Such systems support static and traveling breathers with unusual properties, including double exponential spatial decay, almost vanishing Peierls-Nabarro barrier and spontaneous direction-reversing motion. We prove analytically the existence of surface modes and static breathers for anharmonic on-site potentials and weak Hertzian interactions.

description: Modenverwirbelungskammern (MVK) bieten eine Messumgebung, die sich besonders für Störfestigkeitsuntersuchungen eignet, da auch mit geringer Leistung hohe Prüffeldstärken erreicht werden können, indem Veränderungen geometrischer Randbedingungen zu Feldüberhöhung führen. Diese können statistisch als homogen verteilt im Prüfvolumen angesehen werden. Zunehmend finden MVK auch für die Messung von Antennen oder Transferpfaden Anwendung. Dies geschieht auch bei Frequenzen, die Größenordnungen über der Mindestfrequenz von beispielsweise 30 MHz liegen, wobei die Randbedingungen der MVK grundsätzlich immer als statisch angenommen werden [1]. Bei deutlich höheren Frequenzen, z.B. über 10 GHz, können schon kleine Änderungen der Geometrie die konstruktiven und destruktiven Überlagerungen ändern, weil sie im Bereich/der Größenordnung der Wellenlänge liegen. In [2] wird gezeigt, dass bereits Vibrationen des Tuners oder der Wände Einfluss auf die Feldverteilung in der MVK haben. Diese Vibrationen können einerseits für beabsichtigte Feldveränderungen genutzt werden, andererseits können diese auch von Umgebungseinflüssen kommen und so die Qualität einer Messung in einer vermeintlich als statisch angenommenen MVK beeinträchtigen. Dies zeigen die im vorliegenden Beitrag präsentierten Messungen.

description: Product configurators are a widely used tool to let customers specify an individual variant that best fits to their requirements. The basis for this is a product model that has well defined degrees of freedom and options and so describes the possible solution space. Related to this are design automation systems that aim at automating the design process in order to mimic human designers and assist them in routine design activities. While a lot of configurators and design automation systems is settled in the field of business to consumer applications, some implementations for complex goods like in plant engineering are reported. The present article reports about a design automation system for trash rack cleaners which are used in water management. The basis for the system is a knowledge-based engineering system which uses spreadsheet, constraint and macro technology to create a fully detailed CAD model of the trash rack cleaner.

description: This thesis covered the cases of the use of Soviet power in the field of Sports Of The Uzbek SSR in its various interests. In particular, it has been cited that the working class used precisely the field of sports in increasing their ability to work, in ensuring defensive strength, in increasing the “Cotton plan”. It can be seen that the Soviet authorities, as cadres of the sports sphere of the Uzbek SSR, mainly attracted representatives of other nationalities, on the contrary, a small number of national cadres were taken into this sphere.

description: Adaptive social networks, in which nodes and network structure co-evolve, are often described using a mean-field system of equations for the density of node and link types. These equations constitute an open system due to dependence on higher order topological structures. We propose a new approach to moment closure based on the analytical description of the system in an asymptotic regime. We apply the proposed approach to two examples of adaptive networks: recruitment to a cause model and adaptive epidemic model. We show a good agreement between the improved mean-field prediction and simulations of the full network system.
