description: Evaluating water distribution system modeling is crucial for water supply system management. The study was conducted to evaluate hydraulic performance of system modeling of Bolo town. To achieve the objective, a GIS integrated with a WaterGEMS hydraulic model as a decision-making process in the field of water distribution system modeling was used. A methodology was also developed to collect and analyze data, so that it can be used model an existing water distribution networks, and the results showed significant improvements in the performance of the model. A GIS integrated with a WaterGEMS hydraulic model as a decision-making process in the field of water distribution system modeling was used. The results obtained verified that the water supply in the town was 1165.43 m3 /day, the water supply coverage was 62.85%, and the per capita water demand 48.2 l/c/day. Hence, this result indicates that the annual supply and demand is 37.15% in 2019, which contradicts with GTP-2`s plan of increasing supply coverage to reach 100%. The system developed verified that the pressure at most junction and majority pipes are enough to provide water to customers of the study area. After the hydraulic model was calibrated and validated, the analysis of pressure in the nodes, the velocity in the pipe, through model evaluation statistics was performed, in addition, the value of coefficient of determination (R2 ) and the computed RMSE for pressure calibration was 0.9302 and 4.93m respectively. After the hydraulic analysis, 1.23% of the identified nodes have pressure (>70m) located around Oho area and 6.17% of the nodes have pressure (<15m) around market and high school area. Among the total area, 92.6% of the town have pressure with a permissible limit of (15m to 70m) during peak hour consumption. For the parts of the system that are located far away from the reservoir, and areas with high elevation are facing lack of water due to low pressure. In addition, the approach adopted in this work showed, how the use of Geographic Information System (GIS) integrated with a WaterGEMS hydraulic model find a solution method for water distribution system infrastructure

description: Archaeological excavations at St Giles' Street in the heart of the medieval town and in the eastern suburb of St Edmund's End indicate the nature of occupation in Northampton away from the area of the late Saxon town. Occupation commenced at St Giles' Street in the 11th century at which time it may have formed part of an extra mural market area outside the late Saxon town. Timber buildings are attested from the mid-12th century and a stone building from the late 13th century. The latter was associated with a series of ovens in a yard area to its east. This stone building was abandoned early in the 16th century but after a short hiatus there was subsequently continuous occupation to the present day. The suburban site presents an interesting contrast. Despite its peripheral location occupation began in the 12th century, reflecting Northampton's importance and prosperity at this period. A stone structure was constructed in the mid-13th century but the narrowness of the foundations suggest that this was a dwarf stone wall for a timber superstructure. This building went out of use around the end of the 14th century and thereafter there was no occupation until the 19th century. Accordingly the value of looking at a sample of sites from different areas within a town and the importance of marginal sites in defining periods of growth and decline is emphasised.

description: In this paper, we compute and analyze synthetic radio images of gamma-ray bursts and kilonova afterglows. For modeling the former, we consider GRB170817A-inspired set of parameters, while for the latter, we employ ejecta profiles from numerical-relativity simulations. We find that the kilonova afterglow sky map has a doughnut-like structure at early times that becomes more ring-like at late times. This is caused by the fact that the synchrotron emission from electrons following Maxwellian distribution function dominates the early, beamed, emission while emissions from electrons following power-law distribution is important at late times. For an on-axis observer, the image flux centroid moves on the image plane initially away from the observer. Flux centroid displacement The image sizes, we find, are the largest for equal mass merger simulations with the soft equation of state. The presence of a kilonova afterglow affects the properties inferred from the source sky map even if the gamma-ray burst afterglow dominates the total flux density. The main effect is the reduction of the mean apparent velocity of the source, and an increase in the source size. Thus, neglecting the presence of the kilonova afterglow may lead to systematic errors in the inference of gamma-ray burst properties from the sky map observations. Notably, at the observing angle inferred for GRB170817A the presence of kilonova afterglow would affect the sky map properties only at very late times $t\gtrsim1500\,$days.

description: The emergence of near-ambient temperature superconductivity under pressure in the metal hydride systems has motivated a desire to further understand such remarkable properties, specifically critical magnetic fields. YH$_6$ is suggested to be a departure from conventional superconductivity, due to apparent anomalous behavior. Using density functional calculations in conjunction with Migdal-Eliashberg theory we show that in YH$_6$ the critical temperature and the isotope effect under pressure, as well as the high critical fields, are consistent with strong-coupling conventional superconductivity; a property anticipated to extend to other related systems. Furthermore, the strong-coupling corrections occur to the expected BCS values for the Ginzburg-Landau parameter ($κ_{1}(T)$), London penetration depth ($λ_{L}(T)$), electromagnetic coherence length ($ξ(T)$), and the energy gap ($Δ_{0}$).

description: We have observed the occurrence of dendritic flux avalanches in an amorphous film of Mo$_{84}$Si$_{16}$. These events are understood to have a thermomagnetic origin and involve the abrupt penetration of bursts of magnetic flux taking place within a limited window of temperatures and magnetic fields. While dc-magnetometry allows one to determine the threshold fields for the occurrence of the thermomagnetic instabilities, magneto-optical imaging reveals the spatial distribution of magnetic flux throughout the sample. Conducting appropriate experiments, typical for this goal, avalanches were confirmed to be a characteristic of this material, ruling out the otherwise admissible possibility of an experimental artifact or a feature related to defects in the film. After the present observation, a-MoSi can be included in the gallery of superconducting materials exhibiting flux avalanches when in the form of thin films, a characteristic that must be carefully taken into consideration when one plans to employ films of those materials in applications.

description: We investigated the presence of galaxy overdensities around four $z\sim6$ QSOs, namely SDSS J1030+0524 (z = 6.28), SDSS J1148+5251 (z = 6.41), SDSS J1048+4637 (z = 6.20) and SDSS J1411+1217 (z = 5.95), through deep $r$-, $i$- and $z$- band imaging obtained with the wide-field ($\sim23'\times25'$) Large Binocular Camera (LBC) at the Large Binocular Telescope (LBT). We adopted color-color selections within the $i-z$ vs $r-z$ plane to identify samples of $i$-band dropouts at the QSO redshift and measure their relative abundance and spatial distribution in the four LBC fields, each covering $\sim8\times8$ physical Mpc at $z\sim6$. The same selection criteria were then applied to $z$-band selected sources in the $\sim$1 deg$^2$ Subaru-XMM Newton Deep Survey to derive the expected number of dropouts over a blank LBC-sized field ($\sim$0.14 deg$^2$). The four observed QSO fields host a number of candidates larger than what is expected in a blank field. By defining as $i$-band dropouts objects with $z_{AB}<25$, $i-z>1.4$ and undetected in the $r$-band, we found 16, 10, 9, 12 dropouts in SDSS J1030+0524, SDSS J1148+5251, SDSS J1048+4637, and SDSS J1411+1217, respectively, whereas only 4.3 such objects are expected over a 0.14 deg$^2$ blank field. This corresponds to overdensity significances of 3.3, 1.9, 1.7, 2.5$σ$, respectively. By considering the total number of dropouts in the four LBC fields and comparing it with what is expected in four blank fields of 0.14 deg$^2$ each, we find that high-z QSOs reside in overdense environments at the $3.7σ$ level. This is the first direct and unambiguous measurement of the large scale structures around $z\sim6$ QSOs. [shortened]

description: L’accès d’un sport aux plus jeunes élèves et aux débutants en milieu scolaire est facilité par des adaptations des règles. Celles-ci peuvent, par exemple, s’appliquer sur la dimension d’un terrain, sur la hauteur d’un filet ou sur le nombre de joueurs. Simplifier les règles sportives rend le jeu plus accessible. Les élèves n’étant pas tous des sportifs confirmés, ils jouissent des adaptations et sont ainsi motivés. Plusieurs sports adaptent leurs règles pour être accessibles et attractifs dès le jeune âge des sportifs. Les enseignants en éducation physique adoptent la même approche en offrant une pratique “simplifiée“ et “adaptée“ à leurs élèves. L’éducation physique n’est pas notée dans le canton de Vaud. Les enseignants doivent trouver d’autres pistes pour que leurs élèves soient motivés et s’investissent dans une activité. Les solutions sont entre autres de tenir compte des facteurs motivationnels et physiologiques de l’élève, ainsi que de varier la tâche enseignée. Deux études ont été réalisées lors de ce mémoire. Une étude préliminaire a questionné les futurs enseignants en éducation physique sur les adaptations appliquées lors de leurs enseignements. L’étude principale a quant à elle été réalisée auprès d’élèves de 9ème année Harmos. Elle s’est déroulée sous la forme de deux séquences d’enseignement en badminton et en basket-ball, deux sports liés à la contrainte de verticalité. Les leçons se sont déroulées alternativement en conditions “normales“ et “adaptées“. Le but de la recherche a été de situer l’impression de progression des élèves en conditions “adaptées“. Leur motivation a aussi été observée, afin de la comparer selon les conditions utilisées. Les différentes analyses et réponses obtenues lors de cette étude permettent de répondre par l’affirmative à la question de recherche. La majorité des élèves sont plus motivés et ont une impression de progression plus importante en conditions “allégées“. Les élèves plus “petits“ en taille ont d’ailleurs indiqué que les conditions “adaptées“ leur permettaient d’atténuer les différences. Ils étaient mis en valeur et pouvaient s’exprimer comme leurs camarades.

description: A deux ans de l'introduction de l'anglais à l'école primaire, prévue pour 2015 dans le canton de Vaud et alors que l'allemand sera soumis à évaluation dès la rentrée 2014 aux degrés 5-6H déjà, la question de l'apprentissage des langues est plus que jamais d'actualité. En Suisse, le recensement fédéral de la population de 2000 indique qu'au niveau professionnel l'usage de l'anglais et de l'allemand a progressé. Pour autant, le niveau de langue des élèves après des années d'apprentissage fait débat. D'aucuns relèvent que les résultats en termes de maîtrise des langues sont décevants et mentionnent également la difficulté qu'ont certains à se servir de la langue pour communiquer dans les situations de la vie quotidienne. L'enseignement bilingue, bien que n'existant actuellement pas au secondaire I, serait un moyen d'augmenter l'exposition aux langues des élèves sans surcharger l'horaire, tout en leur permettant d'utiliser les langues étrangères comme outil de communication dans des situations réelles. L'objectif de l'enquête présentée dans ce travail est donc de déterminer si l'implantation de l'enseignement bilingue au secondaire I, plus particulièrement sous la forme de la démarche CLIL, pourrait être envisagée en recourant aux enseignants de disciplines non linguistiques. Ce travail comporte deux volets. D'une part, un aspect théorique, par le biais d'un questionnaire soumis aux enseignants visant à déterminer si des compétences linguistiques suffisantes existent chez eux, leur intérêt envers l'enseignement en langue étrangère, les obstacles et les difficultés qu'ils identifient. D'autre part, un aspect pratique, réalisé sous la forme d'une leçon de sciences en anglais donnée à des élèves du secondaire I, dont le but est de comparer les difficultés rencontrées avec celles relevées par les enseignants dans le questionnaire, d'éprouver la faisabilité sur le terrain d'une telle expérience, et de recueillir les impressions des élèves envers cette démarche.

description: Phase separation accompanied by further domain growth and coarsening is a phenomenon common to a broad variety of dynamical systems. In this connection, controlling such processes represents a relevant interdisciplinary problem. Using methods of numerical modelling, we demonstrate two approaches for the coarsening control in bistable systems based on the example of a spatially-extended model describing an optically-addressed spatial light modulator with two color illumination subject to optical feedback. The first method implies varying system parameters such that the system evolves as the pitchfork or saddle-node normal forms. The second method leverages noise whose intensity is used as an additional system parameter. Both, deterministic and stochastic schemes allow to control the direction and speed of the fronts separating spatial domains. The considered stochastic control represents a particular case of the noise-sustained front propagation in bistable systems and involves the properties of the optical system under study. In contrast, the proposed deterministic control technique can be applied to bistable systems of different nature.

description: BACKGROUND: Among young people who inject drugs (PWID) homelessness is associated with numerous adverse psychosocial and health consequences, including risk of relapse and overdose, psychological distress and suicidality, limited treatment access, and injection practices that increase the risk of HIV and hepatitis C (HCV) transmission. Homeless PWID may also be less likely to access sterile syringes through pharmacies or syringe service programs. METHODS: This study applied random-effects meta-regression to examine trends over time in injection risk behaviors and homelessness among young PWID in Chicago and surrounding suburban and rural areas using data from 11 studies collected between 1997 and 2017. In addition, subject-level data were pooled to evaluate the effect of homelessness on risk behaviors across all studies using mixed effects logistic and negative binomial regression with random study effects. RESULTS: There was a significant increase in homelessness among young PWID over time, consistent with the general population trend of increasing youth homelessness. In mixed-effects regression, homelessness was associated with injection risk behaviors (receptive syringe sharing, syringe mediated sharing, equipment sharing) and exchange sex, though we detected no overall changes in risk behavior over time. CONCLUSIONS: Increases over time in homelessness among young PWID highlight a need for research to understand factors contributing to youth homelessness to inform HIV/STI, HCV, and overdose prevention and intervention services for this population.

description: We describe the target selection and characteristics of the DESI Peculiar Velocity Survey, the largest survey of peculiar velocities (PVs) using both the fundamental plane (FP) and the Tully-Fisher (TF) relationship planned to date. We detail how we identify suitable early-type galaxies (ETGs) for the FP and suitable late-type galaxies (LTGs) for the TF relation using the photometric data provided by the DESI Legacy Imaging Survey DR9. Subsequently, we provide targets for 373 533 ETGs and 118 637 LTGs within the DESI 5-year footprint. We validate these photometric selections using existing morphological classifications. Furthermore, we demonstrate using survey validation data that DESI is able to measure the spectroscopic properties to sufficient precision to obtain PVs for our targets. Based on realistic DESI fiber assignment simulations and spectroscopic success rates, we predict the final DESI PV Survey will obtain $\sim$133 000 FP-based and $\sim$53 000 TF-based PV measurements over an area of 14 000 $\mathrm{deg^{2}}$. We forecast the ability of using these data to measure the clustering of galaxy positions and PVs from the combined DESI PV and Bright Galaxy Surveys (BGS), which allows for cancellation of cosmic variance at low redshifts. With these forecasts, we anticipate a $4\%$ statistical measurement on the growth rate of structure at $z<0.15$. This is over two times better than achievable with redshifts from the BGS alone. The combined DESI PV and BGS will enable the most precise tests to date of the time and scale dependence of large-scale structure growth at $z<0.15$.

title: Deinstitutionalisation and community-based care for adults with intellectual disabilities in Hungary: policy change, challenges and outcomes
Creators: name: Turnpenny, Agnes
Publisher: name: University of Kent
Year: 2023

description: This thesis explores the processes of policy change and outcomes of deinstitutionalisation and community living for adults with intellectual disabilities in the context of a post-communist country, Hungary. The dissertation begins by presenting the international perspective. Using multiple theoretical perspectives it investigates how policies changed and what forces drove the process of deinstitutionalisation in different countries. Some common themes and experiences such as scandals, ideologies, policy learning, and the influence of advocacy coalitions are identified. This is followed by a review of the evaluation literature on the individual outcomes of different residential arrangements for people with intellectual disabilities. The second part of the dissertation presents the policy and practice in residential care in Hungary. Various interpretations of recent policy developments are put forward based on theoretical models of policy change, and the critical analysis of a broad range of policies suggests that residential care policies are resistant to change because institutions are a functional part of the policy system. The third part of the thesis describes the results of a field study looking at the quality of different residential arrangements in Hungary for people with intellectual disability. The thesis concludes with the discussion of the findings and the consideration of implications for national and international policies. It is argued that effective deinstitutionalisation and community living policies should not be based on existing community care policies in Hungary otherwise they risk replacing one set of institutions with another set of smaller scale institutions in the community. Successful policies will also need to address the underlying factors such as discrimination, poverty and the long-term outcomes of the child protection system. A stronger international commitment and surveillance of deinstitutionalisation is also necessary.

Das Potenzial dieser KGs bleibt jedoch aufgrund der begrenzten Vernetzung zwischen ihnen weitgehend ungenutzt. Diese Dissertation befasst sich mit kritischen Forschungslücken im Bereich von Link Discovery (LD) über KGs, insbesondere mit einem Fokus auf geografische KGs. Drei Hauptforschungslücken werden identifiziert: Skalierbarkeitsprobleme (Forschungslücke 1), das Fehlen ganzheitlicher Modelle für Linked Open Data (LOD) (Forschungslücke 2) und die Notwendigkeit für Erklärbarkeit in der LD mit dem Menschen in der Schleife (Forschungslücke 3).
description: The increased availability of heterogeneous Knowledge Graphs (KGs) has unlocked numerous opportunities in data-driven applications, such as information retrieval, Natural Language Processing (NLP), and geospatial analysis. However, the potential of these KGs remains largely untapped due to their limited interlinking. This thesis addresses critical research gaps in the realm of Link Discovery (LD) over KGs particularly focusing on geospatial KGs. Three key research gaps are identified: scalability (Research Gap 1), the absence of holistic models for Linked Open Data (LOD) (Research Gap 2), and the need for explainability in LD with the human in the loop (Research Gap 3).

description: Conçu dans l’optique de relier les pratiques théâtrales et celles de l’enseignement, ce travail se place dans une pédagogie globale de créativité. Ici, on ne cherche pas à donner une méthodologie arrêtée de la manière d’aborder le théâtre en classe. Le parti pris est de rendre le lecteur sensible au bien-fondé de l’utilisation de l’outil-théâtre dans l’enseignement. Tout d’abord, il faut comprendre l’outil-théâtre comme la manière d’amener le théâtre dans un milieu scolaire sous diverses formes. Ce travail vise à expliquer en quoi l’outil-théâtre peut se greffer à différents échelons de la matrice pédagogique. Une première partie est consacrée au lien entre la pratique de l’enseignement et la pratique théâtrale. Le but est de montrer que certains outils théâtraux peuvent amener les enseignants à entrer dans une démarche réflexive et ainsi acquérir, par un travail d’intérêt, plus d’aisance dans leur pratique. La seconde portée de ce travail est de mettre en avant en quoi l’outil-théâtre pratiqué par l’élève peut rentrer dans les attentes du plan d’étude romand. La démarche de ce projet avance en effet que les compétences transversales notamment, essentielles au développement de l’enfant, sont un terreau sur lequel l’outil-théâtre se greffe parfaitement. Le but est également de montrer que l’outil-théâtre peut être un axe de développement des compétences de travail, offrant, par le jeu, des cadres solides transposables tout au long du parcours scolaire de l’enfant. Enfin, le propos de ce travail est également de démontrer que l’ouverture à la culture théâtrale pour les enfants est constructrice dans une optique de création de citoyen responsable. L’intérêt aux arts, principalement aux arts vivants, permet de sensibiliser l’enfant au respect et à la connaissance de l’altérité. L’éducation par l’outil-théâtre permet ainsi d’avoir des effets citoyens si une démarche de créativité a été ouverte en amont. Pour conclure, ce travail vise à expliciter en quoi l’outil-théâtre permet d’améliorer les compétences dans et pour l’enseignement.

description: (Abridged) The radii of debris disks and the sizes of their dust grains are tracers of the formation mechanisms and physical processes operating in these systems. We use a sample of 34 debris disks spatially resolved in various Herschel programs to constrain them. While we modeled disks with both warm and cold components, we focus our analysis only on the cold outer disks, i.e. Kuiper-belt analogs. The disk radii derived from the resolved images reveal a large dispersion, but no significant trend with the stellar luminosity, which argues against ice lines as a dominant player in setting the debris disk sizes. Fixing the disk radii to those inferred from the resolved images, we model the spectral energy distributions to determine the dust temperatures and the grain size distributions. While the dust temperature systematically increases towards earlier spectral types, its ratio to the blackbody temperature at the disk radius decreases with the stellar luminosity. This is explained by an increase of typical grain sizes towards more luminous stars. The sizes are compared to the radiation pressure blowout limit $s_\text{blow}$ that is proportional to the stellar luminosity-to-mass ratio and thus also increases towards earlier spectral classes. The grain sizes in the disks of G- to A-stars are inferred to be several times $s_\text{blow}$ at all stellar luminosities, in agreement with collisional models of debris disks. The sizes, measured in the units of $s_\text{blow}$, appear to decrease with the luminosity, which may be suggestive of the disk's stirring level increasing towards earlier-type stars.

description: String theory in AdS3 with purely NS-NS fluxes and vanishing RR moduli has a continuum of winding string excitations in radial plane wave states. BTZ black holes can emit such strings, which then flow out toward the AdS3 boundary as a stream of massive quanta, and form a black hole analogue of the solar wind. The winding string sector thus provides a decay channel for the black hole to evaporate without having either to couple the system to an external reservoir or to match the AdS3 throat onto an asymptotically flat region. We compute the emission amplitude of this "holar wind" in the semi-classical approximation, and consider the associated version of the black hole information paradox.

description: Ce mémoire s’est développé suite à notre collaboration à un projet mise en place par l’Unité d’enseignement et de recherche (UER) de Pédagogie et Psychologie musicales en collaboration avec l’Unité de production audiovisuelle (UPAV) UER Médias et Tic dans la Formation de la Haute Ecole Pédagogique de Lausanne (HEPL). Ce projet consistait à filmer la préparation d’un spectacle musical prévu dans notre établissement scolaire durant les années scolaires 2011-2012 et 2012-2013 dans lequel participaient six classes du CYT (Cycle de Transition, ancienne loi solaire. Actuellement 7 et 8 Harmos (H)). L’intérêt portait sur un enseignement orienté sur le développement de la créativité, de la communication et de l’implication des élèves et par une démarche correspondant aux nouvelles exigences du Plan d’études romand (PER). Ce travail répond aux questions concernant une pratique d’enseignement favorisant un apprentissage créatif des élèves et essaye de démontrer l’importance de la créativité en collaboration dans le développement de l’autonomie artistique lors de la construction et la représentation d’un spectacle musical. Cette autonomie artistique qui se caractérise par la maîtrise de savoirs disciplinaires (chant, instrument, danse, etc.) et transversaux (collaboration et communication), peut être constatée lors de la représentation filmée du spectacle. A partir d’ici, et pour comprendre notre démarche pédagogique lors de ce projet, nous avons restitué et analysé qualitativement nos actions d’enseignement grâce aux leçons de musique filmées en amont du spectacle et à notre planification générale. Les résultats montrent que le développement de l’autonomie artistique s’est construite progressivement lors des cours de musique où s’imbriquent l’apprentissage rigoureux et structuré des savoirs disciplinaires et le développement des compétences transversales lors de la créativité et la production artistique des élèves. Ce développement se fait grâce à un enseignement créatif qui s’appuie sur une évaluation formative par laquelle a lieu un travail sur la relation par des feed-backs positifs et des marques de confiance données aux élèves lors des régulations des activités.

description: We compute the scattering cross section of Reissner-Nordström black holes for the case of an incident electromagnetic wave. We describe how scattering is affected by both the conversion of electromagnetic to gravitational radiation, and the parity-dependence of phase shifts induced by the black hole charge. The latter effect creates a helicity-reversed scattering amplitude that is non-zero in the backward direction. We show that from the character of the electromagnetic wave scattered in the backward direction it is possible, in principle, to infer if a static black hole is charged.

description: Using recently developed techniques, we consider weak-field test-particle scattering angle calculations in two distinct settings: Charged test-particles in spacetimes of charged sources and Effective One-Body theory with spin. We present scattering angle calculations up to $\mathcal O(G^4)$ of charged particles in the Kerr-Newman metric, including electromagnetic interactions up to second order in charge. Coulomb scattering is also discussed, and the well-known Darwin scattering formula is rederived by resummation. An Effective One-Body metric for a Kerr-Schwarzschild binary is constructed in a post-Minkowskian framework up to $\mathcal O(G^2)$ and first order in spin. Facilitated by explicit scattering calculations, our approach is equivalent with existing literature through gauge-like transformations. Finally, we investigate if the Newman Janis Algorithm applied to an Effective One-Body metric of non-spinning binaries represents a binary system with spin.

description: We report on the feedback stabilization of the zero-phonon emission frequency of a single InAs quantum dot. The spectral separation of the phonon-assisted component of the resonance fluorescence provides a probe of the detuning between the zero-phonon transition and the resonant driving laser. Using this probe in combination with active feedback, we stabilize the zero-phonon transition frequency against environmental fluctuations. This protocol reduces the zero-phonon fluorescence intensity noise by a factor of 22 by correcting for environmental noise with a bandwidth of 191 Hz, limited by the experimental collection efficiency. The associated sub-Hz fluctuations in the zero-phonon central frequency are reduced by a factor of 7. This technique provides a means of stabilizing the quantum dot emission frequency without requiring access to the zero-phonon emission.

description: Efficient light-matter interaction at the single-photon level is of fundamental importance in emerging photonic quantum technology. A fundamental challenge is addressing multiple quantum emitters at once, as intrinsic inhomogeneities of solid-state platforms require individual tuning of each emitter. We present the realization of two semiconductor quantum dot emitters that are efficiently coupled to a photonic-crystal waveguide and individually controllable by applying a local electric Stark field. We present resonant transmission and fluorescence spectra in order to probe the coupling of the two emitters to the waveguide. We exploit the single-photon stream from one quantum dot to perform spectroscopy on the second quantum dot positioned 16$μ$m away in the waveguide. Furthermore, power-dependent resonant transmission measurements reveals signatures of coherent coupling between the emitters. Our work provides a scalable route to realizing multi-emitter collective coupling, which has inherently been missing for solid-state deterministic photon emitters.

description: Depuis une vingtaine d’années, différents traités et accords internationaux, relatifs à l’égalité de tous les individus, incitent les états démocratiques à promouvoir une politique et des pratiques intégratives dans le champ de l’éducation et des besoins éducatifs particuliers. En Suisse, la récente loi fédérale sur la suppression des inégalités frappant les personnes handicapées stipule que les pratiques intégratives doivent primer sur les pratiques séparatives. La pertinence de ce travail tient à deux orientations. Premièrement, à l’heure où les inclusions et les intégrations, concernant les enfants avec des handicaps physiques ou intellectuels, sont largement mises en avant tant dans le champ théorique qu’empirique, peu de recherches se sont intéressées aux situations des enfants avec de sévères troubles du comportement. Dans cette étude, ce sont précisément ces élèves, en situation d’intégration dans une école régulière, qui argumentent au sujet des relations avec leurs pairs dans le contexte de relations informelles, survenant lors de récréations. Deuxièmement, l’angle d’approche de leur intégration se situe à l’intersection de deux thématiques intrinsèques de leur situation singulière. En effet, semblables aux autres élèves en apparence, ce sont en même temps des enfants avec une histoire personnelle pénétrée par une exclusion antérieure de l’école publique. Deux concepts, la métaémotion et le stigmate invisible – constitué de cette exclusion passée – sont les notions-clés qui président à la recherche de la compréhension de leurs constructions discursives, reflétant leur intégration scolaire présente.

description: Lors de ma formation en pédagogie spécialisée à la Haute Ecole Pédagogique du canton de Vaud, j’ai été sensibilisé à l’importance de donner du sens au travail scolaire lequel agit directement sur la motivation de l’élève. C’est pourquoi j’ai décidé de construire avec les élèves de ma classe de développement des séquences hebdomadaires de tutorat dans le but de venir en soutien à des élèves plus jeunes des classes régulières. Cette recherche-action sur cette thématique du tutorat m’a encouragé à permettre aux élèves de l’enseignement spécialisé de s’investir dans un projet pour lequel chacun d’entre eux en est le principal acteur ; et, dans un second temps, à favoriser le développement de leur estime de soi ainsi que de leur autonomie. Ce travail tend également à faire évoluer le regard ainsi que les stéréotypes liés aux élèves de classes de développement. Il met aussi en lumière les apports, les limites et les conditions pour qu’un tel projet soit envisageable. Un arbre de connaissances, a été élaboré et créé avec les élèves, afin de permettre de visualiser leurs compétences préalables « au travers des feuilles de connaissances » ainsi que l’évolution de celles-ci au fil de l’année scolaire. Cette floraison m’a permis de concrétiser les progrès réalisés. De plus, elle a également permis de créer les dyades en fonction des forces des élèves de l’enseignement spécialisé et des difficultés rencontrées par les élèves de l’enseignement régulier. Il est toutefois important de souligner qu’il ne s’agit en aucun cas d’un travail qui évalue la pertinence ou non du tutorat. En effet, de nombreuses études ont été menées et les apports de ce concept ne sont plus à mettre en lumière. Dès lors, ce mémoire professionnel vise principalement à interroger les apports, les limites et les conditions du projet tel que vécu en classe par les élèves tuteurs ainsi que par leurs tutorés.

A critical analysis of shock models for chondrule formation

description: In recent years many models of chondrule formation have been proposed. One of those models is the processing of dust in shock waves in protoplanetary disks. In this model, the dust and the chondrule precursors are overrun by shock waves, which heat them up by frictional heating and thermal exchange with the gas. In this paper we reanalyze the nebular shock model of chondrule formation and focus on the downstream boundary condition. We show that for large-scale plane-parallel chondrule-melting shocks the postshock equilibrium temperature is too high to avoid volatile loss. Even if we include radiative cooling in lateral directions out of the disk plane into our model (thereby breaking strict plane-parallel geometry) we find that for a realistic vertical extent of the solar nebula disk the temperature decline is not fast enough. On the other hand, if we assume that the shock is entirely optically thin so that particles can radiate freely, the cooling rates are too high to produce the observed chondrules textures. Global nebular shocks are therefore problematic as the primary sources of chondrules.

Floquet Engineering to Overcome No-Go Theorem of Noisy Quantum Metrology

description: Permitting a more precise measurement to physical quantities than the classical limit by using quantum resources, quantum metrology holds a promise in developing many revolutionary technologies. However, the noise-induced decoherence forces its superiority to disappear, which is called no-go theorem of noisy quantum metrology and constrains its application. We propose a scheme to overcome the no-go theorem by Floquet engineering. It is found that, by applying a periodic driving on the atoms of the Ramsey spectroscopy, the ultimate sensitivity to measure their frequency characterized by quantum Fisher information returns to the ideal $t^2$ scaling with the encoding time whenever a Floquet bound state is formed by the system consisting of each driven atom and its local noise. Combining with the optimal control, this mechanism also allows us to retrieve the ideal Heisenberg-limit scaling with the atom number $N$. Our result gives an efficient way to avoid the no-go theorem of noisy quantum metrology and to realize high-precision measurements.
