Transient Stability of Grid-forming Voltage-source Converters-Slides
Creators: Heng Wu
Publisher: name: IEEE
Year: 2023

PELS Webinar Slides
Abstract: Grid-forming voltage-source converters (GFM-VSCs) are emerging as an attraction solution for developing the future 100 percent power electronic based power systems. However, different from synchronous generators whose synchronization is governed by the physical law of swing equation, the synchronization dynamics of GFM-VSC is determined by its control algorithm, which brings in difficulties in analyzing the synchronization stability (transient stability) of GFM-VSCs under grid faults. In this webinar, a design-oriented transient stability analysis of GFM-VSCs will be performed based on the phase portrait approach, based on which, the transient stability impact of virtual inertia and damping will be characterized with clear physical insight. In the end, the mode-adaptive control will be further introduced to enhance the transient stability of GFM-VSCs under different operating conditions. This webinar is intended to provide some inspirations of the possibility in utilizing the control flexibility of GFM-VSCs to guarantee a better transient stability performance of future power electronic based power systems.

AI risk management is a key component of responsible development and use of AI sys-
tems. Responsible AI practices can help align the decisions about AI system design, de-
velopment, and uses with intended aim and values. Core concepts in responsible AI em-
phasize human centricity, social responsibility, and sustainability. AI risk management can
drive responsible uses and practices by prompting organizations and their internal teams
who design, develop, and deploy AI to think more critically about context and potential
or unexpected negative and positive impacts. Understanding and managing the risks of AI
systems will help to enhance trustworthiness, and in turn, cultivate public trust.

description: Second- and third-order results are presented for the structure functions of charged-current deep-inelastic scattering in the framework of massless perturbative QCD. We write down the two-loop differences between the corresponding crossing-even and -odd coefficient functions, including those for the longitudinal structure function not covered in the literature so far. At three loops we compute the lowest five moments of these differences for all three structure functions and provide approximate expressions in Bjorken-$x$ space. Also calculated is the related third-order coefficient-function correction to the Gottfried sum rule. We confirm the conjectured suppression of these quantities if the number of colours is large. Finally we derive the second- and third-order QCD contributions to the Paschos-Wolfenstein ratio used for the determination of the weak mixing angle from neutrino-nucleon deep-inelastic scattering. These contributions are found to be small.

description: For this particular doctoral thesis a new software has been created, which determines the linguistic level and measures the difficulty of foreign language tests. Its main aim is to assist in readability issues and also to allow the measurement of text readability with the use of common grading systems, including readability measurement formulas. This software accepts various exam topics in the Italian language, graded or not, and after the text analysis, it classifies these texts in the respective linguistic levels of the language and estimates the level of difficulty of the text. The choice of topics and their integration is done with the sampling method. This particular readability software uses more parameters with increasing discretionary power among the linguistic levels, is able to give direct correspondence between the degree of readability and the linguistic level and estimates the odds that correspond to all linguistic levels and their degree of difficulty.

description: Quantum batteries are energy storage devices that satisfy quantum mechanical principles. How to improve the battery's performance such as stored energy and power is a crucial element in the quantum battery. Here, we investigate the charging and discharging dynamics of a three-level counterdiabatic stimulated Raman adiabatic passage quantum battery via shortcuts to adiabaticity, which can compensate for undesired transitions to realize a fast adiabatic evolution through the application of an additional control field to an initial Hamiltonian. The scheme can significantly speed up the charging and discharging processes of a three-level quantum battery and obtain more stored energy and higher power compared with the original stimulated Raman adiabatic passage. We explore the effect of both the amplitude and the delay time of driving fields on the performances of the quantum battery. Possible experimental implementation in superconducting circuit and nitrogen-vacancy center is also discussed.

description: The dissertation deals with the organization and execution of some simple and clear experimental procedures as well as some parallel activities that can be carried out at any level of secondary education at low cost and without the need for sophisticated equipment. The experiments aim at a better understanding by the students, of the concepts and properties of solutions, such as concentration, density, dilution and mixing. Conducting experiments in a school unit for at least two years proved effective as students in the following school-year were able to respond much more satisfactorily to a specific questionnaire that included questions about the above concepts than students from two other schools who had done only certain or and no related experiments. The statistical analysis of the questionnaires showed that there were significant differences between the three schools and since the evaluation of the questionnaire based on some bibliographical indices has revealed its reliability, it is proposed to be used as a tool for the general assessment of secondary education students.
Art knowledge and the social role of the university art department in the aftermath of postmodernism
Creators: name: Cline Abrahams, Cheryl L.
Publisher: name: University of British Columbia
Year: 2010

description: This study presents a sociology of art knowledge. It explores relationships between art knowledge and institutional structures, making visible how and why certain conceptions of art are hierarchized and generalized so as to be considered essential to the nature of all art. It renders problematic the existing situation in which the art traditionally taught in schools and universities is, for the most part, insular and culturally singular in basis, and examines why this cultural singularity persists in a society which is culturally pluralistic. The thesis is that the university art department has the monopoly on defining, legitimating, and perpetuating this insular and culturally singular art knowledge for transmission through the school' system to all cultural and social groups. The ways in which the university effects art knowledge are discussed in terms of ' the university's curricular structuring and disciplinary ties; its social role as patron, producer, definer, legitimator, and socializer in the arts; and in terms of its ability to neutralize "avant-garde" attacks, including the postmodernist incursion of popular culture into the realm of "sacred" culture. The theoretical framework of this critical analysis is a sociology of knowledge, and the materials for analysis were obtained by reviewing public documents on art programs, policy on the arts in postsecondary education, and a cross-disciplinary selection of literature in social theory, educational theory, aesthetics, and art history. The institutional structures and norms described throughout the study present significant resistance to the postmodernist commitment to challenge conceptual parameters and hierarchies of art knowledge that hinder a broadening of the cultural base of art. The study makes imperative the need to seriously consider this resistance if educational systems are to embrace the artistic activities of a diverse population and if art is to move into a more vital and relevant role in society. It makes imperative for sociological study of art systems (which in the past has concentrated almost exclusively on the role of museums, galleries, critics, dealers, and artists' "lofts") to take into account the role of the university art department as a primary institutional basis of art knowledge, and as a definer of cultural knowledge about art.

description: Propylene oxide is one of the simplest organic chiral molecules and has attracted considerable interest from the scientific community a few years ago, when it was discovered in the interstellar medium. Here, we report a preliminary study on the interaction between propylene oxide and rare-gas atoms, specifically He, Ne, and Ar. The interaction potentials as a function of the distance between the center-of-mass of propylene oxide and the rare-gas-atom are calculated for fourteen leading configurations at CCSD(T)/aug-cc-pVDZ level of theory. Symmetry Adapted Perturbation Theory has been employed for the analysis of the intermolecular potential, revealing that most of the contribution is given by dispersion and exchange forces.

description: The actual physical origin of the gap at the antinodes, and a clear identification of the superconducting gap are fundamental open issues in the physics of high-$T_c$ superconductors. Here, we present a systematic electronic Raman scattering study of a mercury-based single layer cuprate, as a function of both doping level and temperature. On the deeply overdoped side, we show that the antinodal gap is a true superconducting gap. In contrast, on the underdoped side, our results reveal the existence of a break point close to optimal doping below which the antinodal gap is gradually disconnected from superconductivity. The nature of both the superconducting and normal state is distinctly different on each side of this breakpoint.

description: This paper discusses the possibility to use mobile phone network data to monitor spatial policies in land use and transport planning. Monitoring requires robust time series and reproducible concepts linking spatial policies to monitoring outcomes, a requirement differing from current literature where mobile phone data analysis is exemplified in selected areas with privileged data access. Concepts need to serve the evaluation of policy objectives, for example in regional or local area plans. In this study, we, therefore, extend the application of mobile phone network data to monitoring applications comparing urban settlement types and their characteristic mobility patterns. To accomplish this, we link mobile phone records with urban classifications and transport network data, using both visual and computational approaches to mine the data. The article presents comparisons of travel patterns for selected monocentric and polycentric city regions in Germany, testing hypotheses of transit-oriented regional development, as well as testing for congestion risks in the transport network. The results help us to gain a more detailed understanding of spatial and temporal patterns in mobility for different urban types and assess future potentials for monitoring spatial policies with mobile phone network data.

description: We determine analytically the phase diagram of the toric code model in a parallel magnetic field which displays three distinct regions. Our study relies on two high-order perturbative expansions in the strong- and weak-field limit, as well as a large-spin analysis. Calculations in the topological phase establish a quasiparticle picture for the anyonic excitations. We obtain two second-order transition lines that merge with a first-order line giving rise to a multicritical point as recently suggested by numerical simulations. We compute the values of the corresponding critical fields and exponents that drive the closure of the gap. We also give the one-particle dispersions of the anyonic quasiparticles inside the topological phase.

The formalism developed and successfully applied to describe quasielastic scattering has been extended to include both delta production and non-resonant pion production. The results are in fairly good agreement with experimental data over the whole range of energy transfer, including the dip region between the quasielastic peak and the first resonance.

What is bovine Tuberculosis? Using the ethnographic methodology to explore a disease-in-the-making

description: Bovine Tuberculosis (bTB) is arguably the most pressing and contentious livestock disease in England. Since the 1970s, controversy has developed between government, farmers, vets and wildlife groups about the role of badgers in spreading the disease to cattle and how this is managed. The controversy has intensified over the past decade with the introduction of a new statutory disease eradication strategy for bTB, which includes the licencing of badger culling. To date, both policy and research on bTB has widely assumed the singularity of the disease, and suggested that controversy arises from different perspectives about the disease and its management. In contrast, guided by insights from ‘empirical ontology’, I investigate the multiplicity of bTB and how it is made through disease management practices. This research centres on rich empirical material gathered through a multi-sited ethnography that followed bTB through practice, including: skin testing, risk-based trading, evaluating badger culling policy, shooting and cage trapping badgers, anti-cull activism, gassing badgers, and citizen science. Each chapter traces how a practice is being undertaken and how the practice contributes to the making of bTB. I argue that these practices make disease realities which are uniform, controllable and scalable, whilst simultaneously uncertain, unstable and local. These realities are then variously foregrounded and backgrounded according to long-standing perspectives of the disease. I suggest that interventions in practices that explicitly consider bTB as a ‘disease-in-the-making’ could shift disease realities to improve bTB management, and help to move beyond the impasse surrounding the controversy. I also put forward specific interventions in disease management practices, some of which feature in the Government strategy for the control of bTB, updated in 2020.

description: Time series of spectroscopic, speckle-interferometric, and optical long-baseline-interferometric observations confirm that $ν$ Gem is a hierarchical triple system. It consists of an inner binary composed of two B-type stars and an outer classical Be star. Several photospheric spectral lines of the inner components were disentangled, revealing two stars with very different rotational broadening ($\sim$260 and $\sim$140 kms$^{-1}$, respectively), while the photospheric lines of the Be star remain undetected. From the combined spectroscopic and astrometric orbital solution it is not possible to unambiguously cross-identify the inner astrometric components with the spectroscopic components. In the preferred solution based on modeling of the disentangled line profiles, the inner binary is composed of two stars with nearly identical masses of 3.3 M$_\odot$ and the more rapidly rotating star is the fainter one. These two stars are in a marginally elliptical orbit ($e$ = 0.06) about each other with a period of 53.8 d. The third star also has a mass of 3.3 M$_\odot$ and follows a more eccentric ($e$ = 0.24) orbit with a period of 19.1 yr. The two orbits are co-directional and, at inclinations of 79$^{\circ}$ and 76$^{\circ}$ of the inner and the outer orbit, respectively, about coplanar. No astrometric or spectroscopic evidence could be found that the Be star itself is double. The system appears dynamically stable and not subject to eccentric Lidov-Kozai oscillations. After disentangling, the spectra of the components of the inner binary do not exhibit peculiarities that would be indicative of past interactions. Motivations for a wide range of follow-up studies are suggested.

description: The purpose of this study was to investigate whether central adaptations are responsible for. a transfer of fitness to untrained limbs in 13, 9 and 7 CAD/post-MI patients exercising in a walk/jog (WJ) (Legs only) , an aerobic circuit (CT) (arm+legs) program, and a low exercise intensity control group (LC) respectively, for 6 months. Graded exercise tests to determine maximum arm and cycle (leg) aerobic capacity (VO₂peak) and ventilatory threshold (VT) was measured using a SensorMedics Metabolic Measurement Cart, and an arm ergometer and electronically braked cycle ergometer, respectively. Left ventricular (LV) function and absolute volumes (calculated by non-geometric methods) during cycle ergometry were measured by gated bloodpool radionuclide angiograms (RNA). Cycle maximal aerobic capacity (VO₂peak) increased in CT and WJ: 1.96. ± 0.58 to 2.17 ± 0.70 (P<.01) vs. 1.93 ± 0.51 to 2.22 ± 0.54 (P<.004) l-min-1, respectively. Arm VO₂peak increased from 1.32 ± 0.42 to 1.52 ± 0.47 (P<.001) vs. 1.35 ± 0.32 to 1.45 ± 0.34 1-min⁻¹ (P<.01)for the CT and WJ groups, respectively. In both exercise with arm and legs, VT was increased in the WJ and CT groups, but the greatest changes were for VT as expressed as absolute VO₂. Both arm and leg VO₂peak data were correlated with arm and leg VT. The LC group demonstrated no changes in VO₂peak or VT for arms or legs. Peak LV Ejection Fraction (LVEFpeak) increased more in the WJ group than the CT group: 53.3 ± 0.11 to 64.8 ± 0.10 vs. 50.7 ± 0.12 to 55.3 ± 0.11% (P<.02), as did Ejection Rate, and LVESV (changes pre vs. post ; 0.52 vs. -0.13 EDV/sec, and -21.59 vs. 6.89 ml, respectively (P<.05). Cardiac output and stroke volume (SV) increased significantly at rest and exercise in the WJ and CT groups, but Peak total peripheral resistance (TPR) however was related to SV and LVESV (r=-.69 P< .003, r=-.42, P<.05), obscuring apparent intrinsic cardiac adaptations. In addition, neither group demonstrated alterations in body composition and blood lipids as a result of training, despite significant increases in functional capacity. Results suggest that transfer of fitness to untrained limbs in these patients is due in part, but not solely to increased LV function. TPR or other unidentified contributing factors could still account for these effects.

description: It is generally believed that the magnetic free energy accumulated in the corona serves as a main energy source for solar explosions such as coronal mass ejections (CMEs). In the framework of the flux rope catastrophe model for CMEs, the energy may be abruptly released either by an ideal magnetohydrodynamic (MHD) catastrophe, which belongs to a global magnetic topological instability of the system, or by a fast magnetic reconnection across preexisting or rapidly-developing electric current sheets. Both ways of magnetic energy release are thought to be important to CME dynamics. To disentangle their contributions, we construct a flux rope catastrophe model in the corona and solar wind and compare different cases in which we either prohibit or allow magnetic reconnection to take place across rapidly-growing current sheets during the eruption. It is demonstrated that CMEs, even fast ones, can be produced taking the ideal MHD catastrophe as the only process of magnetic energy release. Nevertheless, the eruptive speed can be significantly enhanced after magnetic reconnection sets in. In addition, a smooth transition from slow to fast eruptions is observed when increasing the strength of the background magnetic field, simply because in a stronger field there is more free magnetic energy at the catastrophic point available to be released during an eruption. This suggests that fast and slow CMEs may have an identical driving mechanism.

description: We report direct visualization of gigahertz-frequency Lamb waves propagation in aluminum nitride phononic circuits by transmission-mode microwave impedance microscopy (TMIM). Consistent with the finite-element modeling, the acoustic eigenmodes in both a horn-shaped coupler and a sub-wavelength waveguide are revealed in the TMIM images. Using fast Fourier transform filtering, we quantitatively analyze the acoustic loss of individual Lamb modes along the waveguide and the power coupling coefficient between the waveguide and the parabolic couplers. Our work provides insightful information on the propagation, mode conversion, and attenuation of acoustic waves in piezoelectric nanostructures, which is highly desirable for designing and optimizing phononic devices for microwave signal processing and quantum information transduction.

description: People are increasingly likely to obtain advice from algorithms. But what does taking advice from an algorithm (as opposed to a human) reveal to others about the advice seekers’ goals? In five studies (total N = 1927), we find that observers attribute the primary goal that an algorithm is designed to pursue in a situation to advice seekers. As a result, when explaining advice seekers’ subsequent behaviors and decisions, primarily this goal is taken into account, leaving less room for other possible motives that could account for people’s actions. Such secondary goals are, however, more readily taken into account when (the same) advice comes from human advisors, leading to different judgments about advice seekers’ motives. Specifically, advice seekers’ goals were perceived differently in terms of fairness, profit-seeking, and prosociality depending on whether the obtained advice came from an algorithm or another human. We find that these differences are in part guided by the different expectations people have of the type of information that algorithmic- vs. human advisors take into account when making their recommendations. The presented work has implications for (algorithmic) fairness perceptions and human-computer interaction.

description: The Nikolaevskiy equation has been proposed as a model for seismic waves, electroconvection and weak turbulence; we show that it can also be used to model transverse instabilities of fronts. This equation possesses a large-scale "Goldstone" mode that significantly influences the stability of spatially periodic steady solutions; indeed, all such solutions are unstable at onset, and the equation exhibits so-called soft-mode turbulence. In many applications, a weak damping of this neutral mode will be present, and we study the influence of this damping on solutions to the Nikolaevskiy equation. We examine the transition to the usual Eckhaus instability as the damping of the large-scale mode is increased, through numerical calculation and weakly nonlinear analysis. The latter is accomplished using asymptotically consistent systems of coupled amplitude equations. We find that there is a critical value of the damping below which (for a given value of the supercriticality parameter) all periodic steady states are unstable. The last solutions to lose stability lie in a cusp close to the left-hand side of the marginal stability curve.

description: We define a local Riemann-Roch number for an open symplectic manifold when a complete integrable system without Bohr-Sommerfeld fiber is provided on its end. In particular when a structure of a singular Lagrangian fibration is given on a closed symplectic manifold, its Riemann-Roch number is described as the sum of the number of nonsingular Bohr-Sommerfeld fibers and a contribution of the singular fibers. A key step of the proof is formally explained as a version of Witten's deformation applied to a Hilbert bundle.

description: Background: Recent accumulation of experimental data is revealing the nuclear deformation in vicinity of 42Si. This requests systematic theoretical studies to clarify more specific aspects of nuclear deformation and its causes. Purpose: The purpose of this study is to investigate the nature and cause of the nuclear deformations and its relation to the loss of the neutron magic number N = 28 in vicinity of 42Si. Method: The framework of antisymmetrized molecular dynamics with Gogny D1S density functional has been applied. The model assumes no spatial symmetry and can describe triaxial deformation. It also incorporates with the configuration mixing by the generator coordinate method. Results: We show that the shell effects and the loss of the magicity induce various nuclear deformations. In particular, the N = 26 and N = 30 isotones have triaxially deformed ground states. We also note that the erosion of the N = 28 magicity gradually occurs and has no definite boundaries. Conclusion: The present calculation predicts various nuclear deformations in vicinity of 42Si and suggests that the inter-band electric transitions are good measure for it. We also remark that the magicity is lost without the single-particle level inversion in the oblate deformed nuclei such as 42Si.

Two Energy Release Processes for CMEs: MHD Catastrophe and Magnetic Reconnection

description: It remains an open question how magnetic energy is rapidly released in the solar corona so as to create solar explosions such as solar flares and coronal mass ejections (CMEs). Recent studies have confirmed that a system consisting of a flux rope embedded in a background field exhibits a catastrophic behavior, and the energy threshold at the catastrophic point may exceed the associated open field energy. The accumulated free energy in the corona is abruptly released when the catastrophe takes place, and it probably serves as the main means of energy release for CMEs at least in the initial phase. Such a release proceeds via an ideal MHD process in contrast with nonideal ones such as magnetic reconnection. The catastrophe results in a sudden formation of electric current sheets, which naturally provide proper sites for fast magnetic reconnection. The reconnection may be identified with a solar flare associated with the CME on one hand, and produces a further acceleration of the CME on the other. On this basis, several preliminary suggestions are made for future observational investigations, especially with the proposed KuaFu satellites, on the roles of the MHD catastrophe and magnetic reconnection in the magnetic energy release associated with CMEs and flares.

description: We present two non-parametric deprojection methods aimed at recovering the three-dimensional density and temperature profiles of galaxy clusters from spatially resolved thermal Sunyaev-Zeldovich (tSZ) and X-ray surface brightness maps, thus avoiding the use of X-ray spectroscopic data. In both methods, clusters are assumed to be spherically symmetric and modeled with an onion-skin structure. The first method follows a direct geometrical approach. The second method is based on the maximization of a single joint (tSZ and X-ray) likelihood function, which allows one to fit simultaneously the two signals by following a Monte Carlo Markov Chain approach. These techniques are tested against a set of cosmological simulations of clusters, with and without instrumental noise. We project each cluster along the three orthogonal directions defined by the principal axes of the momentum of inertia tensor. This enables us to check any bias in the deprojection associated to the cluster elongation along the line of sight. After averaging over all the three projection directions, we find an overall good reconstruction, with a small (
