description: Le projet de loi québécois 64 a récemment obtenu la sanction royale. Ce dernier impose de réaliser une Évaluation des facteurs relatifs à la vie privée dans certaines circonstances aux personnes et entreprises détentrices ou utilisatrices de renseignements personnels. Ce processus d’analyse n’a rien de nouveau en soi. En Europe, le Règlement Général sur la Protection des Données exige lui aussi de réaliser une procédure similaire intitulée Analyse d’impact relative à la protection des données dans certaines circonstances. Ce type d’analyse est également une démarche déjà bien établie aux États-Unis et en Australie. Ce document vise à proposer un modèle d’évaluation des facteurs relatifs à la circulation des données basé sur le "Guide des bonnes pratiques en intelligence artificielle: Sept principes pour une utilisation responsable des données" (OBVIA, 2023). Ce modèle est un moyen pour un prestataire d’exposer au grand jour sa diligence et les efforts qu’il entend mener pour traiter les données de façon responsable.

description: The interaction of a quantum system with its environment causes decoherence, setting a fundamental limit on the suitability of a system for quantum information processing. However, we show that if the quantum system consists of coupled parts with different internal energy scales then the interaction of one part with a thermal bath need not lead to loss of coherence from the other. Remarkably, we find that the protected part can become more coherent when the coupling to the bath becomes stronger or the temperature is raised. Our theory will enable the design of decoherence-resistant hybrid quantum computers.

On the optimal feedforward torque control problem of anisotropic synchronous machines: Quadrics, quartics and analytical solutions

Publisher: name: arXiv

Subjects: subject: Systems and Control (eess.SY)
subject: FOS: Electrical engineering, electronic engineering, information engineering

description: The optimal feedforward torque control problem is tackled and solved analytically for synchronous machines while stator resistance and cross-coupling inductance are explicitly considered. Analytical solutions for the direct and quadrature optimal reference currents are found for all major operation strategies such as Maximum Torque per Current (MTPC) (or often called as Maximum Torque per Ampere (MTPA)), Maximum Current (MC), Field Weakening (FW), Maximum Torque per Voltage (MTPV) and Maximum Torque per Flux (MTPF). Numerical methods (approximating the optimal solutions only) or simplifying assumptions (neglecting stator resistance and/or cross-coupling inductance) are no longer necessary. The presented results are based on one simple idea: all optimization problems (e.g. MTPC, MTPV or MTPF) with their respective constraints (e.g. current or voltage limit) and the computation of the intersection point(s) of voltage ellipse, current circle, or torque, MTPC, MTPV and MTPF hyperbolas are reformulated implicitly as quadrics (quadratic surfaces) which allow to solve the feedforward torque control problem by invoking the Lagrangian formalism and by finding the roots of a fourth-order polynomial analytically. The proposed solutions are applicable to any anisotropic (or isotropic) synchronous machine independent of the underlying current control strategy.

description: A common feature of many string-motivated particle physics models is additional strongly coupled U(1)'s. In such sectors, electric and magnetic states have comparable mass, and integrating out modes also charged under U(1) hypercharge generically yields CP preserving electric kinetic mixing and CP violating magnetic kinetic mixing terms. Even though these extra sectors are strongly coupled, we show that in the limit where the extra sector has approximate N = 2 supersymmetry, we can use formal methods from Seiberg-Witten theory to compute these couplings. We also calculate various quantities of phenomenological interest such as the cross section for scattering between visible sector states and heavy extra sector states, as well as the effects of supersymmetry breaking induced from coupling to the MSSM.

description: The aim of the conference paper is to explain in which way the GPN approach could improve our understanding of how the CCS, including design and crafts, operate. The main hypothesis is as follows: the GPN approach allows the most comprehensive understanding of economic, social and spatial organisation of the CCS. The basic research questions are: 1. What are the characteristics of the GPN concept? 2. What differs this concept from previously adopted ones to analyse the CCS? 3. What such notions as value, power and embeddedness bring to the CCS analysis?

Amine functionalized ordered mesoporous silicas for the capture of post combustion flue gas CO₂ via adsorption technologies
Creators: name: Knowles, Gregory Paul

Year: 2017

description: Ordered mesoporous silicas (HMS, SBA-I5 and MCF) were functionalized by aminoalkylsilylation via treatment with aminopropyltrialkoxysilane, ethyelendiaminepropyltrialkoxysilane and diethylenetriamine-propyltrialkoxysilane, and separately loaded with the amine polymers polyethyleneimine and polyallylamine via "wet impregnation" to prepare solid amine sorbents for the potential application to capture the post combustion flue gas CO2 emitted by air fired fossil fuel power generators towards reducing anthropogenic greenhouse gas emissions. Silylations were initially mediated via traditional conventional stirred reactor and refluxing solvent techniques, then subsequently via the assistance of sonication and acid gases and via treatment with silane vapors towards improving the extent of aminoalklylsilylation and thereby the CO2 capacity of the sorbent. Sonication and acid gas treatments were found to lead to higher capacity sorbents than the more traditional preparative techniques. The CO2 capture potential of the sorbents was characterized via a custom modified thermogravimetric analyser combined differential thermoanalyser and a custom made "adiabatic" rig, the potential of the sorbents for CO2 capture via vacuum swing adsorption process technology was in particular targeted, however the sorbents were also considered in the context of a potential temperature swing adsorption process. The sorbents were found to exhibit useful selective CO2 sorption capacities which were achieved via the reversible chemisorption of CO2 via reaction with the amine groups to form ammonium carbamates. The larger porosity OMS sorbents were found to lead to higher capacity sorbents on account of their ability to contain more of the active sorbent phase. Sorption at relatively higher process temperatures, as possible for flue gas, was preferred to achieve the kinetics required for VSA processing of the higher capacity sorbents on account of the temperature dependence of the diffusion of gases through the amine sorbent phase. The high process temperatures lead to decomposition of the sorbent by urea formation via carbamate dehydration, however the incorporation of water into the feed gases (such as is in combustion flue gases) was found to inhibit this process and so validate the potential of these types of materials for the proposed application. The sorbents were otherwise found to exhibit stability. Pelletized forms of the sorbents, such as it is thought would be required for industry application, were prepared via compression either in amine form, or in carbamate form for otherwise solid in liquid dispersions. Such pelletized sorbents were likewise found to exhibit viable, albeit reduced, CO2 working capacities under the conditions tested. Solid amine sorbents prepared were thus found to be a promising potential option for the post combustion capture of CO2 towards reducing anthropogenic greenhouse gas emissions.

description: We theoretically study high-harmonic generation (HHG) from solids driven by intense laser pulses using a one-dimensional model periodic crystal. By numerically solving the time-dependent Schrödinger equation directly on a real-space grid, we successfully reproduce experimentally observed unique features of solid-state HHG such as the linear cutoff-energy scaling and the sudden transition from a single- to multiple-plateau structure. Based on the simulation results, we propose a simple model that incorporates vector-potential-induced intraband displacement, interband tunneling, and recombination with the valence-band hole. One key parameter is the valley-to-peak amplitude of the pulse vector potential, which determines the crystal momentum displacement during the half cycle. When the maximum peak-to-valley amplitude $A_{\rm peak}$ reaches the half width $\fracπ{a}$ of the Brillouin zone with $a$ being the lattice constant, the HHG spectrum exhibits a transition from a single- to multiple-plateau structure, and even further plateaus appear at $A_{\rm peak} = \frac{2π}{a}, \frac{3π}{a}, \cdots$. The multiple cutoff positions are given as functions of $A_{\rm peak}$ and the second maximum $A_{\rm peak}^{\prime}$, in terms of the energy difference between different bands. Using our recipe, one can draw electron trajectories in the momentum space, from which one can deduce, for example, the time-frequency structure of HHG without elaborate quantum-mechanical calculations. Finally, we reveal that the cutoff positions depend on not only the intensity and wavelength of the pulse, but also its duration, in marked contrast to the gas-phase case. Our model can be viewed as a solid-state and momentum-space counterpart of the familiar three-step model, highly successful for gas-phase HHG, and provide a unified basis to understand HHG from solid-state materials and gaseous media.
Bewertung analytischer Planungsmethoden zur Erhöhung der Prognosesicherheit von Rahmenterminplänen bei Bauprojekten

description: In einem Bauprojekt werden in frühen Projektphasen erstmals Dauern für das Projekt durch den Bauherrn prognostiziert und festgehalten. Diese bilden die Grundlage für die weitere (Termin-) Planung. Abweichungen dieser geplanten Dauern haben weitreichende Auswirkungen auf das Projekt und seine Umwelt. Diese Auswirkungen umfassen: Erstens folgt eine Unzufriedenheit seitens der Nutzer oder Betreiber, da vertraglich vereinbarte Zwischen- oder Endtermine nicht eingehalten werden können. Durch diese nicht eingehaltenen Termine können weiter Anforderungen der Stakeholder an den Schnittstellen des Projektes zu seiner Umwelt nicht erfüllt werden. So ist beispielsweise ein verzögerter Produktionsstart, Einzug der Mieter oder eine verzögerte Nutzung mit hohen Kosten verbunden. Drittens können Folgeverzögerungen innerhalb des Projektes entstehen. Viertens ist eine verlässliche Planung der Ressourcen erschwert. Fünftens nimmt der Aufwand und damit die verbundenen Kosten für notwendige Änderungen während der Planung und Ausführung zu. Sechstens können Abweichungen die Projektatmosphäre negativ beeinflussen und Konflikte können entstehen. Zuletzt beeinflussen Abweichungen die Reputation und damit schließlich auch die wirtschaftliche Kraft des jeweiligen Unternehmens. Die Praxis zeigt hingegen anhand vieler Fallbeispiele die Herausforderungen einer möglichst genauen Prognose in frühen Projektphasen: Viele Informationen sind unbekannt und systematische Planungsfehlschlüsse erschweren die Prognose. Mit der Zunahme der Rechenleistung und verfügbaren Daten in einem Bauprojekt stehen analytische Planungsmethoden immer stärker im Fokus der Forschung. Mit diesen werden Daten objektiv ausgewertet, um systematische Planungsfehlschlüsse reduzieren zu können. Aufgrund der Unsicherheit in frühen Phasen stellt sich jedoch die Frage des Potenzials analytischer Planungsmethoden mit begrenzt verfügbaren Daten zum Bauprojekt. Die vorliegende Arbeit hat daher das Ziel, den Einsatz analytischer Planungsmethoden zur Reduktion der Abweichungen von in frühen Phasen eines Bauprojektes geplanten Dauern zu untersuchen. Mithilfe einer explorativen Studie werden erstens Strategien zur Reduktion von Abweichungen geplanter Dauern statistisch untersucht. Zweitens werden ausgewählte analytische Planungsmethoden anhand von Beispieldatensätzen im Hinblick auf ihre Prognosegenauigkeit verglichen. Hier werden die Ergebnisse der Untersuchung zur Prognosegenauigkeit den Erwartungen der Projektbeteiligten an ein zufriedenstellendes Niveau von Abweichungen der frühen Planung gegenübergestellt. Drittens wird anhand eines Beispieldatensatzes die Fehlschätzung analytischer Planungsmethoden der Expertenintuition gegenübergestellt. Mit den Ergebnissen der Arbeit erhalten Bauherren in frühen Phasen eines Bauprojektes Hilfestellungen zur Planung von Dauern in frühen Projektphasen, zur gezielten Anwendung analytischer Methoden und zur Projektdokumentation.

description: The Schlögl system is governed by a nonlinear reaction-diffusion partial differential equation with a cubic nonlinearity. In this paper, feedback laws of Pyragas-type are presented that stabilize the system in a periodic state with a given period and given boundary traces. We consider the system both with boundary feedback laws of Pyragas type and distributed feedback laws of Pyragas and classical type. Stabilization to periodic orbits is important for medical applications that concern Parkinson’s disease. The exponential stability of the closed loop system with respect to the L2-norm is proved. Numerical examples are provided.

description: The objectives of Working Group 3 were the development of standars for the fatigue and impact testing of the chosen MIM materials. Two steels have been selected as representatives of heat treatable high strength material: the 17-4PH precipitation hardened steel, and the low alloy AISI 4340 steel, the last one for conventional quench and temper heat treatments. It became obvious at an early stage of the Thematic Network that a standar defining both the fatigue and impact strength potential f these steels as produced by MIM technology should be demonstrated and the results could be a base for a more extensive research project for the development of the MIM products for high loading applications. The work that was then developed onward was focusing this target. EU Contract No. SMT4-CT97-7505

description: Quantum technologies exploit entanglement to revolutionize computing, measurements, and communications. This has stimulated the research in different areas of physics to engineer and manipulate fragile many-particle entangled states. Progress has been particularly rapid for atoms. Thanks to the large and tunable nonlinearities and the well developed techniques for trapping, controlling and counting, many groundbreaking experiments have demonstrated the generation of entangled states of trapped ions, cold and ultracold gases of neutral atoms. Moreover, atoms can couple strongly to external forces and light fields, which makes them ideal for ultra-precise sensing and time keeping. All these factors call for generating non-classical atomic states designed for phase estimation in atomic clocks and atom interferometers, exploiting many-body entanglement to increase the sensitivity of precision measurements. The goal of this article is to review and illustrate the theory and the experiments with atomic ensembles that have demonstrated many-particle entanglement and quantum-enhanced metrology.

In this work, we applied the higher-order measurement to far-field x-ray diffraction and near-field phase contrast imaging (PCI), in order to achieve superresolution in x-ray diffraction and obtain enhanced intensity contrast in PCI. The cost of implementing such schemes is minimal compared to the methods that achieve similar effects by using entangled x-ray photon pairs.

description: We find, using cosmological simulations of galaxy clusters, that the hot X-ray emitting intra-cluster medium (ICM) enclosed within the outer accretion shock extends out to $R_{\rm shock}\sim(2 - 3) R_{\rm vir}$, where $R_{\rm vir}$ is the standard virial radius of the halo. Using a simple analytic model for satellite galaxies in the cluster, we evaluate the effect of ram pressure stripping on the gas in the inner discs and in the haloes at different distances from the cluster centre. We find that significant removal of star-forming disc gas occurs only at $r \lesssim 0.5 R_{\rm vir}$, while gas removal from the satellite halo is more effective and can occur when the satellite is found between $ R_{\rm vir}$ and $R_{\rm shock}$. Removal of halo gas sets the stage for quenching of the star formation by starvation over $2\textrm{--}3\,\mathrm{Gyr}$, prior to the satellite entry to the inner cluster halo. This scenario explains the presence of quenched galaxies, preferentially discs, at the outskirts of galaxy clusters, and the delayed quenching of satellites compared to central galaxies.

description: The out-of-time-ordered (OTO) correlation is a key quantity for quantifying quantum chaoticity and has been recently used in the investigation of quantum holography. Here we use it to study and characterize many-body localization (MBL). We find that a long-time logarithmic variation of the OTO correlation occurs in the MBL phase but is absent in the Anderson localized and ergodic phases. We extract a localization length in the MBL phase, which depends logarithmically on interaction and diverges at a critical interaction. Furthermore, the infinite-time `thermal' fluctuation of the OTO correlation is zero (finite) in the ergodic (MBL) phase and thus can be considered as an order parameter for the ergodic-MBL transition, through which the transition can be identified and characterized. Specifically, the critical point and the related critical exponents can be calculated.

description: The search for new, application-specific quantum computers designed to outperform any classical computer is driven by the ending of Moore's law and the quantum advantages potentially obtainable. Photonic networks are promising examples, with experimental demonstrations and potential for obtaining a quantum computer to solve problems believed classically impossible. This introduces a challenge: how does one design or understand such photonic networks? We develop novel complex phase-space software for simulating these photonic networks, and apply this to boson sampling experiments. Our techniques give sampling errors orders of magnitude lower than experimental measurements of correlations, for the same number of samples. We show that these techniques remove systematic errors in previous algorithms for estimating correlations, with order of magnitude improvements in errors in some cases. In addition to that, we obtain a scalable channel-combination strategy for assessment of boson sampling devices.

description: This deliverable presents the results of three localisation experiments performed in the 6G BRAINS project. The first hardware realisation experiment aimed to demonstrate RunEL’s capability functionally measuring the location of 5G/6G Mobile User Equipment Terminals (UE) within centimetre accuracy using Time Difference of Arrival (TDoA). The second software simulation experiment aimed to demonstrate how Deep Learning Integrated Reinforcement Learning (DLIRL) algorithm can be used to perform intelligent beamsteering by estimating the Angle of Arrival between gNB smart base station and UE in Beyond fifth Generation (B5G) networks. The third experiment applied a realistic visible light positioning testing environment for analysing and demonstrating that an innovative and data/energy/cost efficient communication system can be used to measure the 3D position by calculating the height of the receiver as well as its x-y position.

description: Nonperturbative renormalization group techniques have recently proven a powerful tool to tackle the nontrivial infrared dynamics of light scalar fields in de Sitter space. In the present article, we develop the formalism beyond the local potential approximation employed in earlier works. In particular, we consider the derivative expansion, a systematic expansion in powers of field derivatives, appropriate for long wavelength modes, that we generalize to the relevant case of a curved metric with Lorentzian signature. The method is illustrated with a detailed discussion of the so-called local potential approximation prime which, on top of the full effective potential, includes a running (but field-independent) field renormalization. We explicitly compute the associated anomalous dimension for O(N) theories. We find that it can take large values along the flow, leading to sizable differences as compared to the local potential approximation. However, it does not prevent the phenomenon of gravitationally induced dimensional reduction pointed out in previous studies. We show that, as a consequence, the effective potential at the end of the flow is unchanged as compared to the local potential approximation, the main effect of the running anomalous dimension being merely to slow down the flow.

description: Despite recent interest and advances in facial micro-expression research, there is still plenty room for improvement in terms of micro-expression recognition. Conventional feature extraction approaches for micro-expression video consider either the whole video sequence or a part of it, for representation. However, with the high-speed video capture of micro-expressions (100-200 fps), are all frames necessary to provide a sufficiently meaningful representation? Is the luxury of data a bane to accurate recognition? A novel proposition is presented in this paper, whereby we utilize only two images per video: the apex frame and the onset frame. The apex frame of a video contains the highest intensity of expression changes among all frames, while the onset is the perfect choice of a reference frame with neutral expression. A new feature extractor, Bi-Weighted Oriented Optical Flow (Bi-WOOF) is proposed to encode essential expressiveness of the apex frame. We evaluated the proposed method on five micro-expression databases: CAS(ME)$^2$, CASME II, SMIC-HS, SMIC-NIR and SMIC-VIS. Our experiments lend credence to our hypothesis, with our proposed technique achieving a state-of-the-art F1-score recognition performance of 61% and 62% in the high frame rate CASME II and SMIC-HS databases respectively.

description: The volume of information on the Web is constantly growing. Consequently, finding specific pieces of information becomes a harder task. Wikipedia, the largest online reference Website is beginning to witness this phenomenon. Learners often turn to Wikipedia in order to learn facts regarding different subjects. However, as time passes, Wikipedia articles get larger and specific information gets more difficult to be located. In this work, we propose an automatic annotation method that is able to precisely assign categories to any textual resource. Our approach relies on semantic enhanced annotations and the categorization schema of Wikipedia. The results of a user study show that our proposed method provides solid results for classifying text and provides a useful support for locating information. As implication, our research will help future learners to easily identify desired learning topics of interest in large textual resources.

description: Gegenstand der Arbeit ist die formale Modellierung des Systemverhaltens verteilter Systeme vom Standpunkt der Systemkontrolle. In dem früher entwickelten formalen Ansatz der Interaktionssysteme (I-Systeme) war das Kern-Prinzip, aus der expliziten Darstellung von lokalen Einflüssen ihre lokalen und globalen Effekte abzuleiten. Dies geschieht durch zwei Typen restriktiver bilateraler Interaktionsbeziehungen. Auf diese Weise scheint das Systemverhalten geprägt durch den Autonomiegrad der Systemkomponenten. Die Arbeit beschäftigt sich mit der Strukturierung des Modellierungskonzeptes und liefert Definitionen und Interpretationen zu Syntax, Dynamik und Semantik von I-Systemen. Ein offenes Problem bestand bisher in der Spezifikation geeigneter Semantiken von I-Systemen, über die sich Schlüsselphänomene im Systemverhalten interagierender Systemkomponenten dokumentieren lassen. Als Lösungsansatz werden hierzu neue Formen von Trace-Semantiken von I-Systemen präsentiert und Unterschiede in deren Ausdruckskräften, auch im Vergleich mit Zustandsgraphen, herausgearbeitet.Die Komplexität in der formalen Modellierung praxisrelevanter verteilter Systeme erzwingt den Einsatz inkrementeller und modularer Entwurfs- und Analysemethoden. Mit Bezug auf die eingeführten Semantiken werden solche Methoden für I-Systeme vorgestellt. Hierbei werden auch I-System-Transformationen mit dem Ziel behandelt, I-Systeme in 'handhabbarere' (bzgl. Entwurf/Analyse/Implementierung) äquivalente I-Systeme umzuformen. Insgesamt liefert diese Arbeit die formale Basis für die Weiterentwicklung der Theorie der I-Systeme.

description: In mechanical engineering, designers have to review a designed artefact iteratively with different domain experts, e.g. from manufacturing, to avoid later changes and find a robust, optimized design. To support the designer, knowledge-based engineering offers a set of approaches and techniques that formalize and implement engineering knowledge into generic product models or decision support systems. An implementation which satisfies especially the concurrent nature of today's design processes and allow for multi-objective decision-making is multi-agent systems. Such systems consist of entities that are capable of autonomous action, interact intelligently with their environment, communicate and collaborate. In this paper, such a multi-agent system is discussed as extension for a computer-aided design software where the agents take the role of domain experts, like e.g. manufacturing technologists and make suggestions for the optimization of the design of mechanical engineering parts. A focal point is set on the collaboration concept of the single agents. Therefore, the paper proposes the use of an action-item-list as central information and knowledge sharing platform. © 2020 The Authors. Published by Elsevier B.V.

description: High energy Astroparticles include Cosmic Ray, gamma ray and neutrinos, all of them coming from the universe. The origin and production, acceleration and propagation mechanisms of ultrahigh-energy CR (up to $10^{20}$ eV) are still unknown. Knowledge on particle interactions taking place at those energies, useful for studying current theories on particle physics, can be obtained only from measurements of high energy astroparticles. In the present document some techniques on data analysis of mass composition of UHECR with the Pierre Auger Observatory are described. The relevance of the muon component of air showers produced by the primary CR, as well as some low energy simulations of that component, are explained.
