description: Many potential indoor sensing and monitoring applications are characterized by hazardous and constantly-changing operating environments. For example, consider emergency response scenarios such as urban fire rescue. Traditionally, first responders have little access to situational information. In-situ information about the conditions, such as the extent and evolution of the indoor fire, can augment rescue efforts and reduce risk to emergency personnel. Static sensor networks that are pre-deployed or manually deployed have been proposed for such applications, but are less practical due to need for large infrastructure, lack of adaptivity and limited coverage. The main hypothesis of this thesis is that controlled-mobile networked sensing – the capability of nodes to move as per network needs, is a novel, feasible, and beneficial approach to monitoring dynamic and hazardous environments. Controlled-mobility in sensor networks can provide the desired autonomy and adaptability to overcome the limitations of static sensors. The research focuses on four of the major challenges in realizing controlled-mobile sensor networking systems: Understanding the trade-off between cost, weight, and sensing and actuation capabilities in designing a hardware platform for controlled-mobile sensing together with a complementary firmware architecture. Designing simulation environments for controlled-mobile sensing platforms that adequately incorporate both the cyber (network, processing, planning) and physical (motion, environment) components of such systems. Investigating the effects of controlled-mobility on network group discovery and maintenance protocols and designing approaches that meet the mobility, latency and energy constraints. Exploring novel low-overhead infrastructure-less mechanisms for collaborative coverage, deployment and navigation of resource-constrained controlled-mobile nodes in previously unseen environments. The thesis validates and evaluates the presented architecture, tools, and algorithms for controlled-mobile sensing systems through extensive simulations and a real-system test-bed implementation. The results show that controlled-mobility is feasible and can enable new class of sensing and monitoring applications.

description: The nonequilibrium quantum dynamics of few boson ensembles which experience a spatially modulated interaction strength and are confined in finite optical lattices is investigated. We utilize a cosinusoidal spatially modulated effective interaction strength which is characterized by its wavevector, inhomogeneity amplitude, interaction offset and a phase. Performing quenches either on the wavevector or the phase of the interaction profile an enhanced imbalance of the interatomic repulsion between distinct spatial regions of the lattice is induced. Following both quench protocols triggers various tunneling channels and a rich excitation dynamics consisting of a breathing and a cradle mode. All modes are shown to be amplified for increasing inhomogeneity amplitude of the interaction strength. Especially the phase quench induces a directional transport enabling us to discern energetically, otherwise, degenerate tunneling pathways. Moreover, a periodic population transfer between distinct momenta for quenches of increasing wavevector is observed, while a directed occupation of higher momenta can be achieved following a phase quench. Finally, during the evolution regions of partial coherence are revealed between the predominantly occupied wells.

description: At the beginning of 2019 the Fedora project reached a significant milestone with the release of v5, the first version to comply with the formally codified Fedora API specification 1.0, which was itself released just a few months before. These are major achievements for our community, and I would maintain that they hold great promise for the future of open repositories, but nevertheless the Fedora project remains at something of a crossroads. The rate of adoption of the re-architected version (>=v4) has been slower than hoped, and many long-standing Fedora users remain on v3, either because they lack the resources to carry out the migration, or because applications in the surrounding ecosystem were found to be difficult to reconcile with a repository based on the Linked Data Platform API. In this presentation I will highlight some of the software standards and tools that have allowed the University of Maryland Libraries to stand up a successful repository stack with Fedora 4 at its core, and some of the emerging efforts in the Fedora community that may enable wider adoption of the system in the future.

description: In this work we develop a scalable computational framework for the solution of PDE-constrained optimal control under high-dimensional uncertainty. Specifically, we consider a mean-variance formulation of the control objective and employ a Taylor expansion with respect to the uncertain parameter either to directly approximate the control objective or as a control variate for variance reduction. The expressions for the mean and variance of the Taylor approximation are known analytically, although their evaluation requires efficient computation of the trace of the (preconditioned) Hessian of the control objective. We propose to estimate this trace by solving a generalized eigenvalue problem using a randomized algorithm that only requires the action of the Hessian on a small number of random directions. Then, the computational work does not depend on the nominal dimension of the uncertain parameter, but depends only on the effective dimension, thus ensuring scalability to high-dimensional problems. Moreover, to increase the estimation accuracy of the mean and variance of the control objective by the Taylor approximation, we use it as a control variate for variance reduction, which results in considerable computational savings (several orders of magnitude) compared to a plain Monte Carlo method. We demonstrate the accuracy, efficiency, and scalability of the proposed computational method for two examples with high-dimensional uncertain parameters: subsurface flow in a porous medium modeled as an elliptic PDE, and turbulent jet flow modeled by the Reynolds-averaged Navier--Stokes equations coupled with a nonlinear advection-diffusion equation characterizing model uncertainty. In particular, for the latter more challenging example we show scalability of our algorithm up to one million parameters resulting from discretization of the uncertain parameter field.

description: Etiolated plant seedlings exposed to light respond by transient accumulation of the nucleus-encoded, plastid-located early light-inducible proteins (Elips). These proteins are distant relatives of the light-harvesting chlorophyll a/b-binding gene family and bind pigments with unusual characteristics. To investigate whether accumulation of Elips in plastid membranes is post-translationally regulated by pigments, reconstitution studies were performed, where in vitro transcribed and translated low molecular mass Elip precursors of barley were combined with lysed barley etioplasts complemented with various compositions of isolated pigments. We showed that the membrane insertion of Elips, as proven by protease protection assays and washes with a chaotropic salt or alkali, depended strictly on chlorophyll a but not on chlorophyll b or xanthophyll zeaxanthin. The amount of inserted Elips increased almost linearly with the chlorophyll a concentration, and the insertion efficiency was not significantly influenced by a light intensity between 1 and 1,000 μmol·m-2·s-1. In contrast, in vitro import of Elip precursors into greening plastids was enhanced by high intensity light. Thus, we conclude that although chlorophylls bound to Elips seem to not be involved in light harvesting, they are crucial for a stable insertion of these proteins into the plastid membrane.

description: In this presentation, we discuss how our library is running our repository in production to meet the needs of our "business" as efficiently as possible. We have an interest in limiting the number of digital platforms we manage for the purposes of sustainability and efficiency, but we must also consider how well a general platform can meet specific user needs. A governance group of administrators, in conference with stakeholders and developers, seeks to find the best way to accommodate each collection or functional need, with an eye to minimizing technical complexity, offering stakeholders self-serve options when possible, and maintaining a single canonical copy of each object. We will present some case studies of how material has been handled in our developing digital ecosystem, where preservation and access sometimes present conflicting priorities. We are exploring how our repository can best evolve to support our aims of making data and documents freely available.

description: The stabilization of multiphase fluid formulations via addition of multiple surface active materials is widespread across various industries and applications. The properties of the air/water and oil/water interfaces that are affected by these materials, including surface tension and elasticity, have been shown to correspond to measurable changes in desirable bulk properties, such as foam and emulsion stability. However, equilibrium interfacial tension values are rarely enough to predict or design stability. Understanding the dynamic interfacial behavior of these materials is critical for improving formulation design. This work aims to characterize the interfacial properties of multi-component systems at air/water and oil/water interfaces. A microtensiometer platform is used to measure interfacial tension and interfacial mechanics to quantify multi-species adsorption under a variety of conditions, including adsorption time, concentration, and ionic strength. This technique is used to characterize several model systems, encompassing nonionic and anionic surfactants, rhamnolipid biosurfactants, hydrophobin proteins and surfactant-particle complexes. Dynamic interfacial tension measurements of surfactant systems reveal the irreversible adsorption behavior of a polymeric surfactant and rhamnolipids, as well as the effects of added small molecule surfactants on their persistence at the interface. For larger adsorbed species, measuring the interfacial mechanics is important to capture adsorption behavior more completely. Through precise control of bulk solution properties, rigid incompressible protein and nanoparticle films are created that can effectively stabilize interfaces. The unique interfacial mechanics of the films are only observed when the interfaces are generated utilizing a controlled adsorption procedure. The results on these model systems highlight the complex nature of the interactions of multiple species on an interface. Systematic modification of the bulk solution allows for the generation of mixed interfaces where interfacial properties that are traditionally confounded by bulk species interaction or dispersion instability can be probed. These interfacial measurements contribute to the overall understanding of the importance of processing as well as composition on desirable formulation properties.

description: Topological quantum states are characterized by nonlocal invariants, and their detection is intrinsically challenging. Various strategies have been developed to study topological Hamiltonians through their equilibrium states. We present a fundamentally new, high-precision dynamical approach, revealing topology through the unitary evolution after a quench from a topological trivial initial state with a two-dimensional Chern band realized in an ultracold $^{87}$Rb atom gas. The emerging ring structure in the spin dynamics uniquely determines the Chern number for the post-quench band and enables probing the full phase diagram of the band topology with high precision. Besides, we also measure the topological band gap and the domain wall structure dynamically formed in the momentum space during the long-term evolution. Our dynamical approach provides a way towards observing a universal bulk-ring correspondence, and has broad applications in exploring topological quantum matter.

description: It is still a challenging task to provide impact indicators other than citations and usage numbers for a repository. Understanding its users is a key element when considering implementing alternative metrics in a repository. Researchers do have specific experiences in working with social media platforms, which might influence the composition of the underlying data (social media mentions) as well as their understanding of the metrics they are confronted with. Within the *metrics project we looked at the technical as well as the user side: with a series of surveys and interviews we studied the attitude of scientists towards social media channels and analysed their motivations and concerns for using the platforms for scientific purposes. In addressing the technical requirements we developed a tool to query a specific set of those social media platforms that users suggested as relevant. Collection of social media mentions needed to cover several identifiers of research output (DOI, handles, ISBN). The integration and adaptation of this tool for EconStor as one of the largest economic repositories is being evaluated by its provider ZBW.

description: We examine the performance of several molecular simulation techniques aimed at evaluation of the surface tension through its thermodynamic definition. For all methods explored, the surface tension is calculated by approximating the change in Helmholtz free energy associated with a change in interfacial area through simulation of a liquid slab at constant particle number, volume, and temperature. The methods explored fall within three general classes: free-energy perturbation, the Bennett acceptance-ratio scheme, and the expanded ensemble technique. Calculations are performed for both the truncated Lennard-Jones and square-well fluids at select temperatures spaced along their respective liquid-vapor saturation lines. Overall, we find that Bennett and expanded ensemble approaches provide the best combination of accuracy and precision. All of the methods, when applied using sufficiently small area perturbation, generate equivalent results for the Lennard-Jones fluid. However, single-stage free-energy-perturbation methods and the closely related test-area technique recently introduced by Gloor et al. [J. Chem. Phys. 123, 134703 (2005)], generate surface tension values for the square-well fluid that are not consistent with those obtained from the more robust expanded ensemble and Bennett approaches, regardless of the size of the area perturbation. Single-stage perturbation methods fail also for the Lennard-Jones system when applied using large area perturbations. Here an analysis of phase-space overlap produces a quantitative explanation of the observed inaccuracy, and shows that the satisfactory results obtained in these cases from the test-area method arise from a cancellation of errors that cannot be expected in general.

description: Considering shock-accelerated protons in addition to electrons in a synchrotron radio jet naturally produces the observed X- through gamma ray continuum emission of flat-spectrum radio-loud AGN, whereas the corresponding shock-accelerated electrons produce the infrared through optical continuum. All of these emission components are rapidly variable on short time scales which can be accounted for by a common origin of the blazar emission in a relativistic sub-parsec scale jet. Moreover, neutrino fluxes are estimated which may be observable with the HiRes experiment and the impact on the ISM of the host galaxy of neutrons escaping from the nuclear jet is investigated.

Control and Design of Snake Robots

Publisher: name: Carnegie Mellon University
Year: 2014
Subjects: subject: 80101 Adaptive Agents and Intelligent Robotics
subject: FOS: Computer and information sciences

description: Snake robots are ideally suited to highly confined environments because their small cross-sections and highly redundant kinematics allow them to enter and move through tight spaces with a high degree of dexterity. Despite these theoretical advantages, snake robots also pose a number of practical challenges that have limited their usefulness in the field. These challenges include the need to coordinate a large number of degrees of freedom, decreased system reliability due to the serially chained nature of the robot’s design, and the complex interaction of the robot’s shape with the world. This thesis makes progress towards addressing these issues with two main areas of contribution. In the first part, we provide tools for supportive autonomy in snake robots. To provide intuitive high-level autonomous behaviors, we extend our lab’s existing gait-based control framework to develop gait-based compliant control. To reliably and accurately sense the robot’s pose and shape we present new techniques for robust state estimation that leverage the redundancies in the distributed sensing capabilities of our group’s articulated snake robots. To demonstrate these contributions in a practical application, we use them to enable a snake robot to navigate a real-world underground pipe network. One of the most limiting characteristics of our snake robots (and robots in general) is the inability to precisely sense and control the torques and forces of their actuators. As such, the second part of this thesis focuses on the design and control of a new series-elastic actuated snake robot that incorporates a high performance series-elastic actuator (SEA) and torque control. After describing the novel design of the SEA, we discuss our perspective on how to incorporate torque control and series elasticity into snake robots. Finally, we demonstrate prototypes of new low impedance motions for snake robots. These motions naturally comply to obstacles and unstructured terrain, and open a new avenue of research for snake robot locomotion.

Valletta Convention

description: More than two decades after the signing of the Valletta Convention, the European Archaeological Council considered it time to draw up a new agenda for how Europe should manage its archaeological heritage. With this purpose in mind, the EAC organised two symposiums that were attended by heritage managers from 25 European countries. At the first event in Saranda, Albania in 2013, the symposium looked back at twenty years of ‘Valletta’, identifying its benefits, problems and challenges. The second symposium was held in Amersfoort, the Netherlands in 2014, and took the form of a working conference. The results included the Amersfoort Agenda for managing the archaeological heritage in Europe. This agenda ties in with the ideas of the Council of Europe’s Faro Convention on the Value of Cultural Heritage for Society (2005). A link is also made with the ideas of the European Union, as expressed in the Conclusions on Cultural Heritage adopted by the Council of the European Union (2014) and a Communication adopted by the European Commission (2014). The Agenda calls for an acknowledgement of the multiple values of archaeological heritage for society and recognises the potential role of archaeological heritage in sustainable development.

description: In der Einleitung wird allgemein über die Bedeutung der Feldflorareservate zum Erhalt der Segetalflora berichtet. Dann wird der Naturraum des Kreises Heidenheim beschrieben. Anschließend werden die Untersuchungsmethoden dargestellt. Sieben Feldflorareservate wurden eingerichtet und detailliert untersucht. Sie sind gleichmäßig über den Kreis Heidenheim auf unterschiedlichen geologischen Schichten verteilt und geben so die Vielfalt sowohl der Wildkrautarten als auch der Pflanzengesellschaften wieder. Zwei Reservate finden sich auf bzw. am Rande von Feuersteinlehmstandorten auf der Gemarkung Steinheim-Söhnstetten, wobei das auf dem Stöckelberg eine für die Winterhalmfrüchte besonders typische Berg-Ackerknäuelgesellschaft (Galeopsio-Aphanetum arvensis), für die Sommerfrüchte eine besonders typische Hohlzahn-Ackerspörgelgesellschaft (Galeopsio-Sperguletum arvensis) zeigt und mit durchschnittlich 52 Spezies recht artenreich ist. Drei Reservate finden sich auf teils oberflächlich verlehmten Schichten des oberen Weißjura (ε bis ζ): Telle bei Heldenfingen, Fliegenberg bei Dischingen und Solitude bei Nattheim, wobei letzteres durch seine Art der Betreuung und seine Dreifelderwirtschaft eine Sonderstellung einnimmt. 9 Arten der Roten Liste Baden-Württembergs wurden dort gefunden. Das sechste Reservat ist der biologisch bewirtschaftete Acker im Haseneck bei Dettingen. Er stockt auf Weißjura ζ im Übergang zum „Lehm auf der Albhochfläche“. Bei den Winterfrüchten hatte er eine durchschnittliche Artenanzahl von 72, dabei waren 11 Arten der Roten Liste Baden-Württembergs zuzuordnen. Das siebte Reservat findet sich am Rande eines Griesbuckels (Weißjura-Auswurf vom Ries) im Mühlfeld auf der Gemarkung Dischingen-Dunstelkingen. Die Pflanzengesellschaften der letzten fünf Reservate sind bei den Winterhalmfrüchten der Finkensamen-Gesellschaft (Sedo-Neslietum paniculatae) und bei den Sommerfrüchten der Hellerkraut-Erdrauchgesellschaft (Thlaspio-Fumarietum officinalis) zuzuordnen. Mit Ausnahme des Ackers in der Telle liegen alle Reservate in Schutzgebieten oder an deren Rand. Außerdem ist ihre Feldflora so bedeutsam, daß sie weiterhin extensiv bewirtschaftet werden sollten.

description: We study the ultrafast structural dynamics, in response to electronic excitations, in heterostructures composed of Au$_{923}$ nanoclusters on thin-film substrates with the use of femtosecond electron diffraction. Various forms of atomic motion, such as thermal vibrations, thermal expansion and lattice disordering, manifest as distinct and quantifiable reciprocal-space observables. In photo-excited, supported nanoclusters thermal equilibration proceeds through intrinsic heat flow, between their electrons and their lattice, and extrinsic heat flow between the nanoclusters and their substrate. For an in-depth understanding of this process, we have extended the two-temperature model to the case of 0D/2D heterostructures and used it to describe energy flow among the various subsystems, to quantify interfacial coupling constants, and to elucidate the role of the optical and thermal substrate properties. When lattice heating of Au nanoclusters is dominated by intrinsic heat flow, a reversible disordering of atomic positions occurs, which is absent when heat is injected as hot substrate-phonons. The present analysis indicates that hot electrons can distort the lattice of nanoclusters, even if the lattice temperature is below the equilibrium threshold for surface pre-melting. Based on simple considerations, the effect is interpreted as activation of surface diffusion due to modifications of the potential energy surface at high electronic temperatures. We discuss the implications of such a process in structural changes during surface chemical reactions.
Fazies, Sequenz-Analyse und stratigraphische Architektur im höheren Oberjura der Schwäbischen Alb (SW-Deutschland)

description: Diese Studie umfaßt eine sedimentologische Neubearbeitung des höheren Malms der Schwäbischen Alb. Die Ziele sind (1) basierend auf einer umfassenden Faziesanalyse und einer Auswertung von Gamma-ray Logs sedimentäre Zyklen und deren Hierarchie zu dokumentieren und (2) die dynamisch-stratigraphische Entwicklung zu rekonstruieren. Dabei wurde die einmalige Gelegenheit genutzt, Explorationsbohrungen zu bearbeiten, die das Landesamt für Geologie, Rohstoffe und Bergbau Baden- Württemberg (LGRB) zur Erkundung neuer Vorkommen von Rohstoffen im Zeitraum von 1997 bis 2000 niedergebracht hat. Um an die oben genannten Aufgabenstellungen systematisch und schrittweise heranzugehen, wurde der konzeptionelle Ansatz der „Dynamischen Stratigraphie“ verwendet. Dabei zeigte sich, daß der Ablagerungsraum der Schwäbischen Alb als tieferer Abschnitt einer Karbonatrampe angesehen werden kann, entlang derer sich die Fazieszonen des distalen und proximalen Beckens, der Biohermränder, der thrombolithischen und der stromatolithischen Bioherme und der Partikelkalke unterscheiden lassen. Innerhalb dieser Fazieszonen konnten drei Hierarchien von sedimentären Zyklen (genetische Sequenzen, mittelskalige und großskalige Sequenzen) erkannt werden, die als Schwankungen des A/S-Verhältnisses interpretiert werden können. Diese Zyklizität spiegelt sich auch im Gamma-Ray Log wieder, wodurch dieses Log ein wichtiges Instrument zur Identifizierung der Zyklizität ist. Die A/S-Zyklen sind unabhängig von der lokalen Fazies und bilden daher ideale Korrelationseinheiten. Profile durch die Schwäbische Alb, die mit Hilfe der Zyklen- und Gamma-Ray-Korrelationen gelegt wurden, gewähren neue Einblicke in die stratigraphische Architektur des schwäbischen Oberjura und erlauben ein dynamisches Faziesmodell zu erstellen.

description: In der Grabungskampagne 2002 konnten etwa 450 Fossilfunde geborgen werden. Wiederum befinden sich darunter viele wissenschaftlich bedeutsame Stücke, aber auch einige Fossilien mit besonderem Schauwert. Hervorzuheben sind Teuthiden-Schulpe mit zugehörigen Kiefern, eine Anzahl gut erhaltener und teilweise neuer Krebse, zwei vollständige Pfeilschwänze, ein Käferrest, eine gestielte Seelilie, eine gut erhaltene Pflanze unbekannter Zugehörigkeit sowie ein großer Samenfarnwedel in organischer Erhaltung. Unter den Wirbeltieren sind mehrere größere Fische zu nennen, darunter ein Aspidorhynchus, ein kleiner Meerengel und drei sehr gut erhaltene, noch zusammen hängende Wirbel eines urtümlichen Reptils (Choristodera). Besonders erwähnenswert ist außerdem der Erstnachweis von Bernstein im Nusplinger Plattenkalk, der sich noch in den Harzkanälen von kohlig erhaltenen Araukarien-Zapfenschuppen fand.

description: Generative models of protein structure enable researchers to predict the behavior of proteins under different conditions. Continuous graphical models are powerful and efficient tools for modeling static and dynamic distributions, which can be used for learning generative models of molecular dynamics. In this thesis, we develop new and improved continuous graphical models, to be used in modeling of protein structure. We first present von Mises graphical models, and develop consistent and efficient algorithms for sparse structure learning and parameter estimation, and inference. We compare our model to sparse Gaussian graphical model and show it outperforms GGMs on synthetic and Engrailed protein molecular dynamics datasets. Next, we develop algorithms to estimate Mixture of von Mises graphical models using Expectation Maximization, and show that these models outperform Von Mises, Gaussian and mixture of Gaussian graphical models in terms of accuracy of prediction in imputation test of non-redundant protein structure datasets. We then use non-paranormal and nonparametric graphical models, which have extensive representation power, and compare several state of the art structure learning methods that can be used prior to nonparametric inference in reproducing kernel Hilbert space embedded graphical models. To be able to take advantage of the nonparametric models, we also propose feature space embedded belief propagation, and use random Fourier based feature approximation in our proposed feature belief propagation, to scale the inference algorithm to larger datasets. To improve the scalability further, we also show the integration of Coreset selection algorithm with the nonparametric inference, and show that the combined model scales to large datasets with very small adverse effect on the quality of predictions. Finally, we present time varying sparse Gaussian graphical models, to learn smoothly varying graphical models of molecular dynamics simulation data, and present results on CypA protein
Collective power: Minimal model for thermodynamics of nonequilibrium phase transitions

description: We propose a thermodynamically consistent minimal model to study synchronization which is made of driven and interacting three-state units. This system exhibits at the mean-field level two bifurcations separating three dynamical phases: a single stable fixed point, a stable limit cycle indicative of synchronization, and multiple stable fixed points. These complex emergent dynamical behaviors are understood at the level of the underlying linear Markovian dynamics in terms of metastability, i.e. the appearance of gaps in the upper real part of the spectrum of the Markov generator. Stochastic thermodynamics is used to study the dissipated work across dynamical phases as well as across scales. This dissipated work is found to be reduced by the attractive interactions between the units and to nontrivially depend on the system size. When operating as a work-to-work converter, we find that the maximum power output is achieved far-from-equilibrium in the synchronization regime and that the efficiency at maximum power is surprisingly close to the linear regime prediction. Our work shows the way towards building a thermodynamics of nonequilibrium phase transitions in conjunction to bifurcation theory.
