Toward Enhancing Stability and Agility of Dynamically Balancing Legged Robots: A Data-Driven Approach
Creators: name: Zamani, Ali
Publisher: name: University of Illinois at Chicago
Year: 2020
Subjects: Uncategorized

description: For legged robots, to be practical, they need to be stable and agile. Stability is the ability to withstand perturbations, and agility is the ability to rapidly accelerate. Both this metrics are challenging to meet for dynamically balancing legged robots which are machines that have point feet or small feet and hence are statically unstable but need to constantly move to achieve dynamical stability. The most well-known method of stabilizing such robots is to generate a periodic or steady motion, also known as a limit cycle and then stabilizing the limit cycle. However, current techniques only provide small perturbation stability for the limit cycle limiting its usefulness. To generate agile gaits, non-steady motion needs to be planned, but is computationally challenging. Although steady state gaits are computationally simple to evaluate, such gaits are not agile. This thesis provides a framework for large perturbation stability of the limit cycle and composition of limit cycles to achieve agile locomotion. The framework is based on assuming a candidate Lyapunov function for step-to-step or orbital stability of the limit cycle. Then a data-driven approach is used to find a nonlinear control policy to stabilize the limit cycle and to estimate the set of initial states that can be stabilized also known as the region of attraction. These regions of attraction are composed using heuristics and sampling-based techniques to achieve agile motion. Finally, the thesis explores a computational approach for real-time planning on complex terrains such as stepping stones. The approach consists of using data-driven techniques to generate and model the step-to-step dynamics around the limit cycle. The resulting model is simple enough to enable real-time nonlinear optimization. Demonstration of these approaches is done using the spring-loaded inverted pendulum model of hopping and compass gait model of walking.

Description of a dynamic simulation model for the control of the complex ecosystem of an infrastructural project

Publisher: name: ----
Year: 2023
Subjects: simulation, management, construction, system dynamics, control, causal loop diagrams, stock and flow

description: This article describes the dynamic simulation model of the construction works of a large industrial infrastructure (Power Plant). The construction activity is a dynamic activity as the complete realization of the infrastructure is achieved through intermediate states of assembly of partial structures, which evolve over time until reaching the final planned configuration. The on-site workforce that performs the construction represent the system, that is, by definition, a set of agents that operate in a coordinated manner according to a predefined project and program. The objective of the system is to complete the work within the given total time while remaining within the planned cost. The result of the construction activity is considered as the emerging structure of the resource system used for that purpose.

The construction activity is analyzed with a systemic approach to highlight the causal relationships between the main variables involved in and, consequently, identify the key parameters of the process. Among the key parameters are included: the time constants of mobilization and demobilization of workforce, their physical productivity of assembling the various substructures, the structural growth factor that characterizes the topology of the elementary substructures.

The proposed model is based on the qualitative causal loop analysis, necessarily simplified to highlight the underlying principle, followed by a Stock & Flow quantitative methodology. It starts from a real project whose data relating to the employed resources and their performance in the field (patterns) were analyzed a posteriori. The model allows Project Managers to perform "what-if" analyzes for initial and intermediate states of progress of the works, taking into account the main parameters affecting the process in order to achieve the objective in a controlled manner.

The methodology is completely general and therefore can be applied to any type of structure.

description: We investigate the crossover from Bardeen-Cooper-Schrieffer (BCS) pairing to a Bose-Einstein condensate (BEC) in a relativistic superfluid within a boson-fermion model. The model includes, besides the fermions, separate bosonic degrees of freedom, accounting for the bosonic nature of the Cooper pairs. The crossover is realized by tuning the difference between the boson mass and boson chemical potential as a free parameter. The model yields populations of condensed and uncondensed bosons as well as gapped and ungapped fermions throughout the crossover region for arbitrary temperatures. Moreover, we observe the appearance of antiparticles for sufficiently large values of the crossover parameter. As an application, we study pairing of fermions with imbalanced populations. The model can potentially be applied to color superconductivity in dense quark matter at strong couplings.

SU(4) generalizations of Halperin's wave functions [Helv. Phys. Acta 56, 75 (1983)], which may break differently the original SU(4) symmetry, are studied analytically and compared, at nu=2/3, to exact-diagonalization studies.

Open research information to inform regional policies: the case of Tuscany Region
Creators: name: Bacci, Lorenzo
Publisher: name: Zenodo
Year: 2024
Subjects: Barcelona Declaration on Open Research Information

description: The Region of Tuscany supports research and innovation activities in its territory through direct R&D funding and through facilitation and coordination actions between the different actors of the regional ecosystem. In order to better inform and support its policies, the Tuscany Region has set up a regional research observatory, which integrates various sources of data and combine metadata on R&D activities, funding and human resources. In this context, the Region has committed to identifying, analysing and integrating open research information into its Observatory, deciding to abandon the use of proprietary research information (in particular for scientific publications) in favour of fully open data sources. In the same view, an internal action has also been launched (in collaboration with various regional government offices) to improve the publication of and access to metadata on research funding. The Tuscany experience is an opportunity to demonstrate the potential and opportunities of open research information to support public policies and to facilitate a better dialogue with regional and national stakeholders, from regional universities to the national evaluation agencies. However, it also shows the challenge faced by public administrations that are too often organised ina ”silos” structure, which is not optimal to deal with transversal challenges, as research should be.

Year: 2020
Subjects: subject: Chemical Physics (physics.chem-ph)

description: Canonical instanton theory is a widespread approach to describe the dynamics of chemical reactions in low temperature environments when tunneling effects become dominant. It is a semiclassical theory which requires locating classical periodic orbits on the upside-down potential energy surface, so-called instantons, and the computation of second order quantum corrections. The calculation of these corrections usually involves a matrix diagonalization. In this paper we present an alternative approach, which requires to solve only linear systems of equations involving sparse matrices. Furthermore, the proposed method provides a reliable and numerically stable way to obtain stability parameters in multidimensional systems, which are of particular interest in the context of microcanonical instanton theory.

description: The ab initio full-potential linearized augmented plane-wave method explicitly designed for the slab geometry was employed to elucidate the physical origin of the layer potentials for the trilayers nFe/3Cr/nFe(001), where n is the number of Fe monolayers. The thickness of the transition-metal ferromagnet has been ranged from $n=1$ up to n=8 while the spacer thickness was fixed to 3 monolayers. The calculated potentials were inserted in the Fuchs-Sondheimer formalism in order to calculate the giant magnetoresistance (GMR) ratio. The predicted GMR ratio was compared with the experiment and the oscillatory behavior of the GMR as a function of the ferromagnetic layer thickness was discussed in the context of the layer potentials. The reported results confirm that the interface monolayers play a dominant role in the intrinsic GMR.

It is found that the magnetic form factor G*M decreases with Q2 more steeply than the proton magnetic form factor, the ratio E1+/M1+ is small and negative, indicating strong helicity non-conservation, and the ratio S1+/M1+ is negative, while its magnitude increases with Q2.

description: We demonstrate spin polarized jets in extended systems of ballistic exciton-polariton condensates in semiconductor microcavities using optical non-resonant excitation geometries. The structure of the spin jets is determined by the digitally reprogrammable, spatially non-uniform, degree of circular polarization of the excitation laser. The presence of the laser excitation, strong particle interactions, and spin-relaxation leads to a tunable spin-dependent potential landscape for polaritons, with the appearance of intricate polarization patterns due to coherent matter-wave interference. Our work realizes polarization-structured coherent light sources in the absence of gauge fields.

description: AIMS. We present a new Ks-band survey that represents a significant extension to the previous wide-field Ks-band imaging survey within the 0226-04 field of the VIMOS-VLT deep survey (VVDS). The new data add ~ 458 arcmin^2 to the previous imaging program, thus allowing us to cover a total contiguous area of ~ 600 arcmin^2 within this field. METHODS. Sources are identified both directly on the final K-band mosaic image and on the corresponding, deep chi^2-g'r'i' image from the CFHT Legacy Survey in order to reduce contamination while ensuring us the compilation of a truly K-selected catalogue down to the completeness limit of the Ks-band. The newly determined Ks-band magnitudes are used in combination with the ancillary multiwavelength data for the determination of accurate photometric redshifts. RESULTS. The final catalogue totals ~ 52000 sources, out of which ~ 4400 have a spectroscopic redshift from the VVDS first epoch survey. The catalogue is 90% complete down to K_Vega = 20.5 mag. We present K_s-band galaxy counts and angular correlation function measurements down to such magnitude limit. Our results are in good agreement with previously published work. We show that the use of K magnitudes in the determination of photometric redshifts significantly lowers the incidence of catastrophic errors. The data presented in this paper are publicly available through the CENCOS database.

Subjects: Barcelona Declaration on Open Research Information

description: Open scholarly metadata databases present the advantage of enabling more compared to closed databases in terms of use and reuse of information, transparency, and reproducibility. However, there is still room for improvement regarding the accuracy and completeness of key metadata. Since some of the registries used as a source in those global databases are community-led, it is possible for anyone to actively contribute to their improvement.

The talk will first address some of the challenges involved in identifying the reasons for discrepancies in the results of analyses carried out with open databases compared to closed databases. It will then introduce actions that have the potential to significantly improve the metadata quality in open infrastructures.

Instanton rate constant calculations using interpolated potential energy surfaces in non-redundant, rotationally and translationally invariant coordinates

description: A trivial flaw in the utilization of artificial neural networks in interpolating chemical potential energy surfaces (PES) whose descriptors are Cartesian coordinates is their dependence on simple translations and rotations of the molecule under consideration. A different set of descriptors can be chosen to circumvent this problem, internuclear distances, inverse internuclear distances or z-matrix coordinates are three such descriptors. The objective is to use an interpolated PES in instanton rate constant calculations, hence information on the energy, gradient and Hessian is required at coordinates in the vicinity of the tunneling path. Instanton theory relies on smoothly fitted Hessians, therefore we use energy, gradients and Hessians in the training procedure. A major challenge is presented in the proper back-transformation of the output gradients and Hessians from internal coordinates to Cartesian coordinates. We perform comparisons between our method, a previous approach and on-the-fly rate constant calcuations on the hydrogen abstraction from methanol and on the hydrogen addition to isocyanic acid.

The model presents a wide variety of exponents between 1/2 and 1 for this scaling, revealing their dependence on the few parameters considered, and questioning the existence of universality classes. We also report the experimental scaling of the fluctuations in the Internet for the Abilene backbone network. We found scaling exponents between 0.71 and 0.86 that do not fit with the exponent 1/2 reported in the literature.

Embodying Science: Latinx Children’s Knowledge and Identity Construction While Studying Water
Creators: name: Kotler, Rebecca T
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: The body is often ignored, in elementary science education, as a site of knowledge, meaning, and feeling. This study explored how embodied performances, defined as drama- and movement-based representations of science ideas, spontaneous or rehearsed, shaped construction and communication of science knowledge and identities among Latinx fifth graders in an urban school. The perspective central in this study is informed by embodied cognition, social semiotics, multimodality, aesthetic learning, and drama pedagogy, coupled with embracing sociocultural approaches to meaning making, identity theory, and justice-centered science education. In this instrumental case study, within the context of a year-long water curriculum that addressed issues of sustainability, contamination, and justice, embodied performances and other multimodal artifacts were analyzed in order to shed light on children’s construction of science knowledge, including sociopolitical understandings, and science identities. Multimodal discourse analysis and movement analysis (focusing on Body, Effort, Shape, Space) of videotaped classroom lessons and conversations with students led to four findings. Children transduced meanings across modes and translated meanings within modes, extending each other’s thinking and building ideas in collective ways. The dialogic reflections that occurred during and after planned performances provided critical spaces and places where children constructed science knowledge and identities. Multiple embodied performances of the same science concept offered a heightened level of engagement as many interpretations and comparisons became possible. Finally, perspective-taking engaged children in not only considering science ideas about lead contamination of drinking water but also developing critical consciousness of policies that impact health, and agentic identities that embrace caring, advocacy, and peoples’ rights to healthy lives. These findings suggest that interrogating how embodying science extends opportunities to construct science knowledge and agentic identities is a productive area of exploration. Furthermore, the findings compel researchers and practitioners at the crossroads of science, performing arts, and justice-centered pedagogies to develop curricula and pedagogical practices that nurture and probe more deeply the various affordances that embodied performances offer for strengthening science learning.
Park facility development and design planning facilities that respect the spirit of place

description: As the political, economic and cultural fabric of all regions of the British Columbia landscape grows more sophisticated, legislative remedies to environmental issues will become more difficult to execute. If our society's values towards resources are to change, the resource protection field may need to evolve from legislated protection to cultural protection based on appreciation and peer pressure. In this regard, natural park sites have the potential to influence the values which will be carried beyond that particular site. Protective attitudes towards the environment often grow out of a feeling of connection to, and an understanding of, particular places. The act of conferring park status on a natural place acknowledges that we consider it to be special and hence worthy of protection. The way in which this environment is planned, designed and managed has the potential to demonstrate environmental protection values while educating people about the natural world and our impact upon it. Retaining the true "spirit of place" in a natural area park is a worthy goal but often difficult to achieve. In British Columbia's Provincial Park System, a dual mandate to provide for recreational pursuits while protecting the environment creates problems for staff who must fulfill what is often a conflicting prescription. A detailed policy framework for facilities, based on explicitly examined values, would provide direction for decision making about park facilities. This thesis looks at the topic of retaining a "sense of place" in natural area parks, examines the issue of values and tradeoffs in park management, and offers a planning framework to operationalize the B.C. Parks mandate to protect and present provincial parks.

description: Metadata conveys the provenance, evidence, results of, and responses to research. This once-geeky afterthought has become one of the most important tools in progressing the open science movement and the growing attention on open metadata rightly reflects the growing urgency for open science. But opening up metadata doesn’t just happen; multiple ‘nudges’ have taken place over the years, both coordinated and transparent, as well as uncoordinated and behind closed doors. Learning from prior initiatives and actions, we will cover some ideas for what it may take to speed up open metadata for open science, and what infrastructure organisations like Crossref are doing and can do to support the effort.

description: Anderson's orthogonality catastrophe (AOC) theorem establishes that the ground state of the many-body fermion system is asymptotically orthogonal to the ground state of the same system perturbed by a scattering potential, so that the overlap between the original and new ground states decays to zero with the system size. We adopt the AOC for a description of heat production in a complementary metal-oxide-semiconductor (CMOS) transistor. We find that the heat released in the transistor comprises two distinct components, contribution from the dissipation accompanying electron transmission under the applied voltage and purely quantum-mechanical AOC part due to the change in scattering matrix for electrons upon switching between high and low conductance regimes. We calculate the AOC-induced heat production, which we call switching heat.

description: The nature of the World Wide Web entails, conceptually and technically, the principle of universality. Anyone can benefit and contribute to it. The net paradigm based on decentralization has been critical to the Web’s growth and innovation. It is also a key factor in achieving diversity. Open infrastructures providing open research information acting as digital public goods should comply with criteria such as relevance to Sustainable Development Goals, open licenses, clear ownership, platform independence, documentation, mechanisms for extracting data, among others. The sustainability of such digital public goods should be secured collectively and the universal service they provide should be assessed. In Latin America, the dissemination of knowledge has been the responsibility of the academic and research sectors, mainly sustained with public funds. Its components, such as journals and repositories, have been open by default and they provide a universal service. The condition of diversity of knowledge, methodologies, research agendas, metadata richness, and languages is directly proportional to the capacity of inclusivity and interconnectivity of diverse open data sources. Today, Latin America has important research information infrastructures, at the regional and national levels, as well as thousands of journals and hundreds of repositories articulated at different levels and layers of interoperability to generate new public goods from existing ones, within an interconnected ecosystem of knowledge. However, it is also very important to note the degradation of public goods due to the adoption of commercial strategies, and some public policies and practices that are limiting the scope of open data integration, such as inequities in technology access and the necessary involvement of those traditionally underrepresented groups. Building on data sources of research information to enable digital public goods is a sustainable and responsible way to contribute to fulfill the commitments of the Barcelona Declaration.

description: VIVO and OpenAlex are complementary initiatives in the realm of open research information. VIVO, an open-source software, focuses on the aggregation of profiles of actors in science to enable visualization of an institution’s scholarly activities through comprehensive profiles of researchers, their publications, projects, and aQiliations.

OpenAlex serves as a global index of scholarly publications with a massive database of scholarly works, authors, institutions, and accompanying metadata. In this presentation, we will highlight the power and benefit to all involved stakeholders of connecting opensource software, built with open standards, to open research information. These benefits include sovereignity over the metadata of an institution’s research activities and output, plus improved and enriched metadata for OpenAlex, the institution using VIVO, and all potential consumers of that data across the global research community.

VIVO can utilize OpenAlex’s vast metadata to fill its profiles, ensuring that researchers’ outputs are more accurately represented and more easily discoverable. At the same time, OpenAlex can benefit from the rich, structured data provided by VIVO, such as affiliation details and project specifics, to deepen the context and accuracy of its records.

description: The Bardeen-Cooper-Schrieffer (BCS) condensation and the Bose-Einstein condensation (BEC) are the two extreme limits of the ground state of the paired fermion systems. We report crossover behavior from the BCS condensation to the BEC realized in the two-dimensional (2D) superconductor, electron doped layered material ZrNCl. The phase diagram, established by simultaneous experiments of resistivity and tunneling spectra under the ionic gating, demonstrates the pseudogap phase at the low doping regime. In the low carrier density limit, $T_{\rm BKT}$ (Berezinskii-Kosterlitz-Thouless transition temperature for 2D superconductors) scales as $T_{\rm BKT}/T_{\rm F} = 0.12$, where $T_{\rm F}$ is the Fermi temperature, which is consistent with the theoretical upper bound expected in the BCS-BEC crossover regime. The present results indicate that the gate-doped semiconductor provides an ideal platform for the 2D BCS-BEC crossover without any added complexity, such as magnetic orders and density waves.

description: We report on the electrostatic complexation between oppositely charged polymers and inorganic nanoparticles investigated by static and dynamical light scattering. The nanoparticles put under scrutiny were citrate-coated nanocrystals of cerium oxide (CeO2, nanoceria), of iron oxide (Fe2O3, maghemite) and of europium-doped yttrium vanadate (Eu:YVO4) with sizes in the 10 nm range. For the polymers, we have used cationic-neutral diblock copolymers (poly(trimethylammonium ethylacrylate)-b-poly(acrylamide), hereafter referred to as PTEA-b-PAM) with different molecular weights. For the three colloidal dispersions, we show that the electrostatic complexation gives rise to the formation of stable nanoparticle clusters in the 100 nm range. The complexation was monitored by systematic measurements of the scattering intensity versus X, the mixing ratio between nanoparticles and polymers. For 5 nanoparticle/polymer pairs, namely CeO2/PTEA5K-b-PAM30K, Fe2O3/PTEA5K-b-PAM30K, Fe2O3/PTEA11K-b-PAM30K, Eu:YVO4/PTEA2K-b-PAM60K and Eu:YVO4/PTEA5K-b-PAM30K, we found a unique behavior : the scattering intensity exhibits a sharp and prominent peak in the intermediate X-range. To account for this behavior, we have developed a model which assumes that regardless of X, the mixed aggregates are formed at a fixed polymer-to-nanoparticle ratio. The agreement between the results and the model is excellent on the 5 systems. Results at different molecular weights suggest that the stoichiometry of the mixed aggregates is controlled by the electrostatic interactions between the opposite charges. The model allows to derive the molecular weight and the stoichiometry of the mixed aggregates.

Mira B Rejuvenated

description: Recent ultraviolet spectra from the Hubble Space Telescope (HST) and Far Ultraviolet Spectroscopic Explorer (FUSE) satellites demonstrate that UV line and continuum fluxes observed from Mira B are increasing back towards the levels that the International Ultraviolet Explorer observed in 1979-1980 and 1990-1995, after having been found in a very low state by HST and FUSE in 1999-2001. The UV emission is associated with accretion of material onto Mira B from Mira A's massive wind, so the variability is presumably due to variations in accretion rate. From wind absorption features, we estimate a Mira B mass loss rate of 2.5e-12 M_sun/yr, indicating that Mira B's wind has increased in strength along with the accretion rate. The UV variability may be associated with a previously reported 14-year periodicity in Mira B's optical emission.

The role and potential of Vietnamese Ngos in the context of Doi Moi
Creators: name: Mulla, Zarina
Publisher: name: University of British Columbia

description: Among the significant global events that have characterized the last decade has been the political and economic restructuring in socialist countries. A vital dimension of this policy has been the introduction of the market system and a rethinking of socialist principles of equality. As the formerly-provided state subsidies for social services are being cut back, the population has to struggle to adjust itself to the market system. This has contributed among other things, to social polarization. The case of Vietnam provides a typical example of a socialist economy in transition. Economic renovation or Doi Moi has produced economic benefits for the country but also social dilemmas for the population. As a result of market forces, health and education systems have deteriorated, unemployment has increased, food distribution within the country has been disrupted and gender inequality and income disparity are on the rise. In the midst of this transition, some non governmental organizations (NGOs) have emerged to respond to inadequate governmental planning in resolving the social consequences of economic restructuring. This thesis is an informative and analytical study of the current and potential role of Vietnamese NGOs in addressing socio-economic conditions in the context of economic renovation in Vietnam. Interviews with thirteen NGOs, identified through "snowball" sampling methods in Hanoi and Ho Chi Minh City during a period of twelve weeks (Nov.93-Feb 94) indicate the following: Vietnamese NGOs are mostly involved in providing relief and welfare services; they are not engaged in any advocacy (an indispensable method for many NGOs in the world); and have virtually no connection with the international NGO network. Although their total impact on socio-economic development is not yet substantial given the extent of social changes under Doi Moi, their existence at all is significant for Vietnam today. It is important that their efforts be recognized, nationally and by international counterparts. Korten's typology of the four generations of NGOs provides a useful framework in identifying the current role of Vietnamese NGOs and in speculating on their potential to evolve along the developmental continuum as proposed in the typology. In conclusion, NGOs all over the world have been the true forces of social progress and sustainable development. This thesis argues that as has been the case historically with NGOs in other developing countries, Vietnamese NGOs, given the proper support, have the potential to evolve as organs of community development and social justice.
