description: Using a longitudinal design, the present study seeks to improve our understanding of what drives heterogeneity in students’ perceptions of teaching quality by investigating the role of teachers’ diagnostic competence. Specifically, our hypotheses are as follows:
H1. Students’ ratings of teachers’ diagnostic competence are negatively related to heterogeneity in student perception of instructional quality, controlling for the effects of achievement on individual instructional quality ratings.
H2. Students’ ratings of teachers’ diagnostic competence predict changes in heterogeneity in student perception of instructional quality, controlling for effects of changes in achievement on individual instructional quality ratings.
Details on how we intend to test our hypotheses can be found in the appended document, which is a preregistration for secondary data analysis, following the recommendations of Mertens and Krypotos (2019).

description: Variation in environmental factors throughout time can result in life history adaptations for species. Odonates are important components of stream ecosystems and play key roles in the functioning of stream food webs. Since they are present in both aquatic and terrestrial habitats, they are excellent model organisms to study these interactions. The objective of this study is to evaluate temporal and spatial (e.g. habitat) changes in Odonata assemblages in El Yunque National Forest and assess which environmental variables might be associated with the assemblages. We established a 100m transect in two first order streams for larvae collection, divided in 5m meter segments. Each month, five segments were randomly chosen and sampled using hand nets in pools and riffles for 15 min per segment. Larvae were sorted from benthic material and preserved in ethanol. Temperature, canopy cover, stream width and type of substrate at each segment were also measured. Larval abundance was significantly higher in riffles than in pools in both streams. Scapanea frontalis Burmeister and Macrothemis celeno Selys in Sagra were the most abundant for both streams with 346 and 62 individuals, respectively. Analysis of size distribution resulted in a similar pattern for both streams with larvae with smaller head width (<1.5mm) being more abundant. We also did not find evidence of cohort development, as small and large larvae were present in the same months. Overall, Odonata assemblages favored flowing water habitats and had limited temporal variability in the study streams.

description: Emergent model spectra of neutron star atmospheres are widely used to fit the observed soft X-ray spectra of different types of isolated neutron stars. We investigate the effect of Compton scattering on the emergent spectra of hot (T_eff > 10^6 K) isolated neutron stars with weak magnetic fields. In order to compute model atmospheres in hydrostatic and radiative equilibrium we solve the radiation transfer equation with the Kompaneets operator. We calculate a set of models with effective temperatures in the range 1 - 5 * 10^6 K, with two values of surface gravity (log g = 13.9 and 14.3) and different chemical compositions. Radiation spectra computed with Compton scattering are softer than those computed without Compton scattering at high energies (E > 5 keV) for light elements (H or He) model atmospheres. The Compton effect is more significant in H model atmospheres and models with low surface gravity. The emergent spectra of the hottest (T_eff > 3 * 10^6 K) model atmospheres can be described by diluted blackbody spectra with hardness factors ~ 1.6 - 1.9. Compton scattering is less important in models with solar abundance of heavy elements.

description: Σκοπός της παρούσας διπλωματικής εργασίας ήταν η μελέτη και η απόδοση του πολιτισμικού στοιχείου σε ένα προς μετάφραση λογοτεχνικό κείμενο και ο ρόλος που αυτό διαδραματίζει στο πλαίσιο της μεταφραστικής διαδικασίας. Η έρευνα βασίστηκε στη μελέτη τόσο του πρωτοτύπου όσο και του μεταφράσματος των τριών αστυνομικών μυθιστορημάτων Το μαύρο Αλγέρι, Η κόκκινη Μασσαλία και το Παρίσι μπλουζ, του Μωρίς Αττία. Μέσα από την βιβλιογραφική ανασκόπηση αλλά και την αντιπαραβολική μελέτη, των έργων που επιλέχθηκαν ως ερευνητικό αντικείμενο, αναδείχθηκε ο βαθμός στον οποίο ο πολιτισμός επηρέασε και συνεχίζει να επηρεάζει τη μεταφρασεολογική επιστήμη και σκέψη, αλλά και το γεγονός ότι αποτελεί βασικό γνώμονα της ίδιας της μεταφραστικής πράξης, αφού καθορίζει τις μεταφραστικές αποφάσεις που πρέπει να ληφθούν. Τέλος, καταλήξαμε στο συμπέρασμα ότι το πολιτισμικό στοιχείο γενικά, σε ένα κείμενο λογοτεχνίας ειδικά, κατέχει σημαντικές διαστάσεις που δεν δύνανται να παραληφθούν από το μεταφραστή, οι επιλογές του οποίου έγκεινται κυρίως στους στόχους που οφείλει να εκπληρώσει το πρωτότυπο κείμενο αλλά και τις επιδιώξεις, όπως και τους κανόνες που διέπουν τον πολιτισμό υποδοχής, ενώ σημαντική θέση κατέχει και η προσωπική του επιθυμία να εκπληρώσει ή όχι τις προσδοκίες τόσο του ενός όσο και του άλλου
description: The aim of this diploma thesis was to study cultural elements in a literary text for translation, in their very essence, as well as the strategies and techniques used for their transfer in a foreign language and civilization, in addition with the active role they take in the process of translation. The research was based on the study of both the original and the translation of the following crime novels, Alger la Noire, Pointe Rouge and Paris blues, written by the French author Maurice Attia. Through the bibliographical review as well as the comparative study of the novels selected we gave prominence to the extent to which culture has already affected in the past and continues to affect the field of translation studies, in addition to the fact that it constitutes a substantial guideline of the translation act itself, since it determines the decisions that need to be made by the translators. The conclusion reached is that cultural elements in general, in a literary text in particular, are of great extent that cannot be overlooked by the translator, whose choices mainly lie on the goals to be fulfilled by the original text, as well as the aims and rules prevailing in the host culture, while the translator’s personal desire, to fulfill or not the expectations of both sides, is also of great importance

description: The full physics potential of the next-generation Deep Underground Neutrino Experiment (DUNE) is still being explored. In particular, there have been some recent studies on the possibility of improving DUNE's neutrino energy reconstruction. The main motivation is that a better determination of the neutrino energy in an event-by-event basis will translate into an improved measurement of the Dirac $CP$ phase and other neutrino oscillation parameters. To further motivate studies and improvements on the neutrino energy reconstruction, we evaluate the impact of energy resolution at DUNE on an illustrative new physics scenario, viz. non-standard interactions (NSI) of neutrinos with matter. We show that a better energy resolution in comparison to the ones given in the DUNE conceptual and technical design reports may significantly enhance the experimental sensitivity to NSI, particularly when degeneracies are present. While a better reconstruction of the first oscillation peak helps disentangling standard $CP$ effects from those coming from NSIs, we find that the second oscillation peak also plays a nontrivial role in improving DUNE's sensitivity.

description: Our experimental and theoretical study of the non-crystalline and crystalline components of the anisotropic magnetoresistance (AMR) in (Ga,Mn)As is aimed at exploring the basic physical aspects of this relativistic transport effect. The non-crystalline AMR reflects anisotropic lifetimes of the holes due to polarized Mn impurities while the crystalline AMR is associated with valence band warping. We find that the sign of the non-crystalline AMR is determined by the form of spin-orbit coupling in the host band and by the relative strengths of the non-magnetic and magnetic contributions to the impurity potential. We develop experimental methods directly yielding the non-crystalline and crystalline AMR components which are then independently analyzed. We report the observation of an AMR dominated by a large uniaxial crystalline component and show that AMR can be modified by local strain relaxation. We discuss generic implications of our experimental and theoretical findings including predictions for non-crystalline AMR sign reversals in dilute moment systems.

description: We discuss the possibility of simultaneous and sequential synchronisation in vertical and horizontal arrays of unidirectionally coupled discrete systems. This is realized for the specific case of two dimensional Gumowski-Mira maps. The synchronised state can be periodic,thereby bringing in control of chaos, or chaotic for carefully chosen parameters of the participating units. The synchronised chaotic state is further characterised using variation of the time of synchronisation with coupling coefficient, size of the array etc. In the case of the horizontal array, the total time of synchronisation can be controlled by increasing the coupling coefficient step wise in small bunch of units.

description: Spin-orbit interaction in a quantum dot couples far infrared radiation to non center of mass excitation modes, even for parabolic confinement and dipole approximation. The intensities of the absorption peaks satisfy the optical sum rule, giving direct information on the total number of electrons inside the dot. In the case of a circularly polarized radiation the sum rule is insensitive to the strength of a Rashba spin-orbit coupling due to an electric field orthogonal to the dot plane, but not to other sources of spin-orbit interaction, thus allowing to discriminate between the two.

description: We explore some thermodynamical consequences of accelerated universes driven by a running cosmological constant (CC) from the renormalization group (RG). Application of the generalized second law (GSL) of gravitational thermodynamics to a framework where the running of the CC goes at the expense of energy transfer between vacuum and matter, strongly restricts the mass spectrum of a (hypothetical) theory controlling the CC running. We find that quantum effects driving the running of the CC should be dominated by a trans-planckian mass field, in marked contrast with the GUT-scale upper mass bound obtained by analyzing density perturbations for the running CC. The model shows compliance with the holographic principle.

description: The submillimeter CO lines are formed in warm and dense molecular gas and are therefore sensitive to the physical conditions whereas the CO (J=1-0) line is a tracer of the total molecular gas mass. In order to be able to compare the properties of molecular gas in nearby and distant galaxies, we have observed C and CO submillimeter lines (including the 12CO(6-5) and 12CO(7-6) lines) in a sample of nearby galaxies using the CSO. We have obtained a complete view of the CO cooling curve (also called CO spectral energy distribution) by combining the submillimeter CSO data with previous observations found in the literature. We made use of Large Velocity Gradient (LVG) models to analyse the observed CO cooling curve, predict CO line intensities from J=1-0 to J=15-14 in the studied galaxies, and derive the physical properties of the warm and dense molecular gas : the kinetic temperature (TK); the gas density (n(H2)); the N(12CO)/$Δv$. The predictions for the line intensities and for the total CO cooling power, obtained from LVG modelling have been compared with predictions from Photo Dissociation Regions (PDR) models. We show how the CO SED varies according to the galaxy star forming activity. For active nuclei, the peak is located near the 12CO(6-5) or 12CO(7-6) rotational lines, while, for normal nuclei, most of the energy is carried by the 12CO(4-3) and 12CO(5-4) lines. Whatever the spectral type of the nucleus, the observed C cooling rate is lower than the observed CO cooling rate (by a factor of around 4). The CO cooling curve of nearby starburst galaxies (e.g. NGC 253) has a quite similar shape to the CO cooling curve of distant galaxies. Therefore, the CO cooling curves are useful diagnostics for the star forming activity in distant objects.

description: We study symmetry breaking and topological defects in a supersymmetric model with gauge group $\text{U}(2)$, which can be identified with the right-handed part $\text{SU}(2)_R \times \text{U}(1)_{B-L}$ of an extended electroweak symmetry of the Standard Model. The model has two phases of hybrid inflation terminated by tachyonic preheating where either monopoles and strings or, alternatively, dumbbells are formed. In the first case a stochastic gravitational wave background is predicted in the LIGO-Virgo band, possibly extending to the LISA frequency band and to nanohertz frequencies, which is generated by a metastable cosmic string network. In the second case no topological defects survive inflation and no stochastic gravitational wave background is produced.

Το πρώτο ιστορικό αφήγημα που αναλύεται είναι το έργο του φράγκου μοναχού Dudo του saint-Quentin με τίτλο De Moribus et Actis Primorum Normanniae Ducum. Το έργο αυτό που γράφτηκε μάλλον στις αρχές του 11ου αιώνα κατόπιν παραγγελίας του Νορμανδού δούκα Ριχάρδου Β’(996-1026), αναδεικνύει το παγανιστικό αλλά συνάμα ηρωικό παρελθόν των προγόνων της ηγεμονεύουσας νορμανδικής ελίτ ταυτίζοντας την ύπαρξη των Νορμανδών ως πολιτική κοινότητα με την αδιάρρηκτη συνέχεια και ευημερία της κυρίαρχης νορμανδικής δυναστείας. Όλοι οι επόμενοι νορμανδοί συγγραφείς που το έργο τους αναλύεται στον παρόν έγγραφο, όπως ο Γουλιέλμος του Jumieges, o Ορδέριχος Vitalis και ο Ροβέρτος του Torigni, αντλούν ιστορικά στοιχεία από το έργο του Dudo και ανασκευάζουν την εικόνα των Νορμανδών ώστε αυτή να ανταποκρίνεται στις νέες προκλήσεις και συνθήκες που επικρατούν. Η δανική καταγωγή, το ηρωικό παγανιστικό παρελθόν, η χριστιανική πίστη, καθώς και η γη της Νορμανδίας διαδραματίζουν ουσιαστικό ρόλο στης κατασκευή της νορμανδικής ταυτότητας. Ωστόσο όλα τα παραπάνω δεν παύουν να αποτελούν παρά εργαλεία στα χέρια των συγγραφέων με σκοπό να τονίσουν το θεμελιώδες χαρακτηριστικό που συγκροτεί τη νορμανδική κοινότητα: την ηγεσία των νορμανδών δουκών.
description: In the present study I try to present the ways that the image of the Normans is constructed in the historical narratives produced to the duchy of Normandy from the end of the 10th century to the middle of the 12th century. The first historical narrative being analyzed is the work of the frankish monk Dudo of Saint-Quentin bearing the title De Moribus et Actis Primorum Normanniae Ducum. The text, probably written in the beginning of the 11th century after being ordered by the norman duke Richard II(996-1026), gives prominence to the pagan yet at the same time heroic past of the ancestors of the ruling norman elit and the existence of the Normans as a political community is linked inexorably with the continuation and prosperity of the dominant norman dynasty. The rest Norman authors that their texts are analyzed in this paper, that is William of Jumieges, Orderic Vitalis and Robert of Torigni, use the work of Dudo as the basic historical source and reconstruct the image of the Normans to meet the new challenges and changing conditions of their time. The danish ancestry, the heroic pagan past, the christian faith and the land of Normandy play an essential role to the construction of the norman identity. Nevertheless, the aforementioned elements are nothing but tools used by the authors to give emphasis to the fundamental element that constitutes the norman community; the leadership of the Norman dukes.

description: We propose a variant of the heterodyne holography scheme that combines the properties of off-axis and phase-shifting holography. This scheme makes it possible to filter off numerically the zero-order image alias and the technical noise of the reference. It is then possible to record and reconstruct holographic images at an extremely low signal level. We show experimentally that the sensitivity of the method is limited only by the quantum nature of photons.

description: Binary systems of a hot subdwarf B (sdB) star + a white dwarf (WD) with orbital periods less than 2-3 hours can come into contact due to gravitational waves and transfer mass from the sdB star to the WD before the sdB star ceases nuclear burning and contracts to become a WD. Motivated by the growing class of observed systems in this category, we study the phases of mass transfer in these systems. We find that because the residual outer hydrogen envelope accounts for a large fraction of an sdB star's radius, sdB stars can spend a significant amount of time ($\sim$10s of Myr) transferring this small amount of material at low rates ($\sim 10^{-10}$-$10^{-9}\ M_\odot\,\rm yr^{-1}$) before transitioning to a phase where the bulk of their He transfers at much faster rates ($\gtrsim 10^{-8}\ M_\odot\,\rm yr^{-1}$). These systems therefore spend a surprising amount of time with Roche-filling sdB donors at orbital periods longer than the range associated with He star models without an envelope. We predict that the envelope transfer phase should be detectable by searching for ellipsoidal modulation of Roche-filling objects with $P_{\rm orb}=30$-$100$ min and $T_{\rm eff}=20{,}000$-$30{,}000$ K, and that many ($\geq$10) such systems may be found in the Galactic plane after accounting for reddening. We also argue that many of these systems may go through a phase of He transfer that matches the signatures of AM CVn systems, and that some AM CVn systems associated with young stellar populations likely descend from this channel.

Automatic infant cry analysis and recognition

Publisher: name: University of British Columbia
Year: 2009

description: This dissertation is a report of my investigation on introducing modern speech process ing/recognition techniques to the field of infant cry research, and on developing efficient and effective methodologies for automatic assessment of the physical/emotional situation of infants using the information derived from the cry signals. I first identify some problems facing present infant cry research, especially those obstruct ing the practical applications of the results generated from basic research. By demonstrating the similarities between infant cry generation and adult speech generation, I establish the theoretical foundation for the development of my new automatic cry processing/analysis tech niques. In particular, I develop the new concept of cry phonemes as an effective method for representing cry signals for automatic cry analysis. Based on the cry phonemes, I further define a composite parameter, the H-value, which can be calculated from the cry signal, and is found to be a reliable indicator of the distress level of the infant. Using these new concepts, I design two automatic infant cry analysis systems. One system is based on my newly developed nonparametric VQ-kernel classifier, and the other system is based on the Hidden Markov Model technique. Each of these systems estimates the H-value from the cry signal automatically. This, in turn, is utilized in the automatic assessment of the infant’s distress level. The performance of these two systems was evaluated with cries uttered by 36 infants. I found that both systems give assessments of infants’ distress levels consistent with the perceptions of experienced parents who listened to the recording of the same cries. This demonstrates the effectiveness of my newly developed techniques. In addition, the methodologies developed in this research can be easily generalized and applied to other problems of normal and abnormal infant cry analysis.

description: Integrated semiconductor mode-locked lasers have shown promise in many applications and are readily fabricated using generic InP photonic integration platforms. However, the passive waveguides offered in such platforms have relatively high linear and nonlinear losses that limit the performance of these lasers. By extending such lasers with, for example, an external cavity the performance can be increased considerably. In this paper, we demonstrate for the first time that a high-performance mode-locked laser can be achieved with a butt-coupling integration technique using chip scale silicon nitride waveguides. A platform-independent SiN/SU8 coupler design is used to couple between the silicon nitride external cavity and the III/V active chip. Mode-locked lasers at 2.18 GHz and 15.5 GHz repetition rates are demonstrated with Lorentzian RF linewidths several orders of magnitude smaller than what has been demonstrated on monolithic InP platforms. The RF linewidth was 31 Hz for the 2.18 GHz laser.

description: The final state interactions in $K^\pm\toπ^\pmπ^0π^0$ decays are considered using the methods of non-relativistic quantum mechanics. We show how to take into account the largest electromagnetic effects in the analysis of experimental data, using the amplitudes calculated earlier. We propose the relevant expressions for amplitude corrections valid both above and below the two charged pion production threshold $M_{π^0π^0}=2m_{π^\pm}$, including the average effect for the threshold bin. These formulae can be used in the procedure of pion scattering lengths measurement from $M_{π^0π^0}$ spectrum.

description: We investigate the behavior of null geodesics near future null infinity in asymptotically flat spacetimes. In particular, we focus on the asymptotic behavior of null geodesics that correspond to worldlines of photons initially emitted in the directions tangential to the constant radial surfaces in the Bondi coordinates. The analysis is performed for general dimensions, and the difference between the four-dimensional cases and the higher-dimensional cases is stressed. In four dimensions, some assumptions are required to guarantee the null geodesics to reach future null infinity, in addition to the conditions of asymptotic flatness. Without these assumptions, gravitational waves may prevent photons from reaching null infinity. In higher dimensions, by contrast, such assumptions are not necessary, and gravitational waves do not affect the asymptotic behavior of null geodesics.

description: Η παρούσα έρευνα αφορά στις αντιδράσεις των γονέων όταν τους ανακοινώνεται από τα διεπιστημονικά κέντρα η διάγνωση για την αναπηρία του παιδιού τους και συνοδεύεται από πρόταση για φοίτηση σε ειδική δομή. Συγκεκριμένα αναζητούνται οι παράγοντες που επιδρούν και επηρεάζουν τους γονείς με αποτέλεσμα άλλες φορές οι αντιδράσεις τους απέναντι στην διάγνωση και στην πρόταση των διεπιστημονικών κέντρων να είναι θετικές και άλλες αρνητικές. Τα αποτελέσματα έδειξαν ότι σημαντικό ρόλο για τις αντιδράσεις των γονέων απέναντι στις διαγνώσεις που τους δίνονται παίζουν οι απόψεις τους για τα ειδικά σχολεία αλλά και οι αντιλήψεις τους για την καταλληλότητα και την κατάρτιση της διεπιστημονικής ομάδας που συμμετέχει στη διάγνωση και στελεχώνει τα διεπιστημονικά κέντρα.
description: The current research deals with the parents' reaction when they are confronted with a diagnosis regarding their child's disability from an interdisciplinary center that suggests attendance in a special structure of education. Moreover, the thesis is investigating the factors that affect and influence the parents’ viewpoint resulting in variable reactions towards the diagnosis and the suggestions of the interdisciplinary center either positive or negative. The research results have indicated that the parents' reactions regarding the suggested diagnoses are largely influenced by their perspective regarding special schools and their perceptions regarding the adequacy and the expertise of the specialized interdisciplinary team who is responsible for the implementation of the diagnostic procedure in interdisciplinary centers.

description: The gap between the rich and the poor is increasing and negatively impacting a raft of social and health outcomes (Wilkinson & Pickett, 2019). Nevertheless, people’s desire for greater equity (Norton & Ariely, 2011; Galdi, 2016) rarely translates into support for concrete redistribution strategies such as support for progressive taxation, recognized as an effective tool for reducing economic inequalities (Kaplow & Shavell, 2002; Pressman, 2014; Piketty, 2015; Stiglitz, 2017). Therefore, investigating the barriers to tax compliance is crucial. Literature suggests that taxpayer compliance can be increased involving citizens in the process of tax choice (Lamberton et al., 2018). Tax choice is a strategy that allows citizens to get involved in the process of allocating tax revenues to specific public goods, a task that is generally reserved to parliaments. Different from other types of frames, this strategy focuses on the process rather than the outcome (Alm, 2018) and hence may shift people’s perception of procedural justice surrounding taxation. Although research on tax choice suggests that such choice frames substantially increase the amount of taxes that people consider fair and that they are willing to contribute (Abbiati et al., 2014; Alm, 2018), as well as their tax compliance (Casal et al., 2016), little attention is given to the role of choice overload in affecting this relationship (see Chernev et al, 2015 for a review). Drawing on Schwatz (2004) this study aims to test wheter the number of choices presented to citizens may affect people’s tax compliance. Indeed, despite multiple benefits, a large number of options may increase the cognitive cost associated with the choice, and therefore, choice complexity (see, for example, Iyengar & Lepper, 2000).
To test the effect of preference expression, we will manipulate participants’ perception of tax choice through an experimental paradigm, structured for this specific study. Specifically, participants will be randomly assigned to one of two conditions (control vs. choice). In the first condition (control condition) participants will be presented with a brief description of tax money allocation from the Government. In the second condition (choice condition) participants will be randomized into 1 of 10 sub-conditions, where we will manipulate the number of options available (from 2 to 20) for participants’ choice about taxes. Subsequently, we will provide participants with a scale of tax compliance, satisfaction with the choice, trust in government spending procedural justice and demographics.

description: In this paper, we derive an asymptotic error expansion for the eigenvalue approximations by the lowest order Raviart-Thomas mixed finite element method for the general second order elliptic eigenvalue problems. Extrapolation based on such an expansion is applied to improve the accuracy of the eigenvalue approximations. Furthermore, we also prove the superclose property between the finite element projection with the finite element approximation of the eigenvalue problems by mixed finite element methods. In order to prove the full order of the eigenvalue extrapolation, we first propose "the auxiliary equation method". The result of this paper provides a general procedure to produce an asymptotic expansions for eigenvalue approximations by mixed finite elements.

Cancellation of arbitrary tone interference for all-digital high definition television transmitted over coaxial cable networks
Creators: name: Marsland, Ian D.
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis a novel canceller of a completely unknown tone which is interfering with a digital quadrature amplitude modulation (QAM) signal operating in an additive white Gaussian noise (AWGN) environment is proposed, analysed and evaluated. This canceller can be applied to protect all-digital high definition television (HDTV) signals from tone interference, which arises from intermodulation products, a common source of distortion in cable television networks. Expressions for the optimal weights for the linear minimum mean-square enor (MMSE) filter, consisting of L delay elements, for cancelling the tone interference are derived, under the condition that the tone’s frequency and power are known to the canceller. It is shown that the MMSE is directly proportional to the combined power of the QAM signal and the Gaussian noise, and inversely proportional to L. Furthermore, as the characteristics of the tone are assumed to be completely unknown, novel fast Fourier transform (FFT) based methods for estimating the frequency and power of the tone are proposed and analysed. By using these estimates in place of the true values for the optimal weights, a suboptimal filter is derived. Performance evaluation results have shown that the performance of the suboptimal canceller is, for all practical purposes, identical to the optimal one. To improve the performance further, without increasing the number of the filter’s delay elements, a decision feedback mechanism is employed to reduce the power of the data signal. Through a combination of analytical and computer simulated performance evaluation it is found that for all practical purposes the proposed decision feedback tone canceller removes the tone interference completely.

description: Aerodynamic forces render accurate high-speed trajectory tracking with quadrotors extremely challenging. These complex aerodynamic effects become a significant disturbance at high speeds, introducing large positional tracking errors, and are extremely difficult to model. To fly at high speeds, feedback control must be able to account for these aerodynamic effects in real-time. This necessitates a modelling procedure that is both accurate and efficient to evaluate. Therefore, we present an approach to model aerodynamic effects using Gaussian Processes, which we incorporate into a Model Predictive Controller to achieve efficient and precise real-time feedback control, leading to up to 70% reduction in trajectory tracking error at high speeds. We verify our method by extensive comparison to a state-of-the-art linear drag model in synthetic and real-world experiments at speeds of up to 14m/s and accelerations beyond 4g.

description: The stability of entanglement of two atoms in a cavity is analyzed in this work. By studying the general Werner states we clarify the role of Bell-singlet state in the problem of suppression of disentanglement due to spontaneous emission. It is also shown explicitly that the final amount of entanglement depends on the initial ingredients of the Bell-singlet state.

Subjects: subject: Social and Behavioral Sciences

description: This multimethod prospective longitudinal study will examine the roles of a range of intrapersonal (e.g., perfectionism, HEXACO personality traits, social comparison, motivation for learning) and interpersonal (e.g., social connection, school environment) factors related to mental health, adjustment, and well-being among students during the COVID-19 pandemic. Further, we will examine how these factors changes across time (e.g., intrapersonal factors, interpersonal factors, mental health, adjustment, well-being). We plan on testing the potential moderating role of transition year status (e.g., whether the adolescent is in grades 8, 9, 12 or first year of post-secondary), gender identity, age, and perceived control within these relationships. With respect to personality (i.e., perfectionism), we will be testing three competing theoretical models linking perfectionism and mental health, adjustment, and well-being outcomes (i.e., vulnerability model, scar model, reciprocal model). We will also be testing potential explanatory mechanisms in the relationship between personality and mental health, adjustment, and well-being (e.g., stress, social connection, social comparison, motivation/strategies for learning). We will also test the unique predictive utility of perfectionism with respect to mental health, adjustment, and well-being over and above broader personality traits (i.e., HEXACO). Not all models and variables will be tested at the same time. Half-longitudinal quantitative designs will be tested when data from two time points have been collected, and full longitudinal designs will be tested when data from all three timepoints have been collected.
Using qualitative research methods (e.g., semi-structured interviews), we will be exploring the lived experiences of a subset of our participants, including their experiences of the COVID-19 pandemic, definitions of and experiences with perfectionism, and the ways in which they use online and in person social connection during the pandemic. We plan on linking these interview transcripts to their survey responses to examine whether youth experiences during the pandemic vary as a function of gender identity, age and/or whether they self-identify as a perfectionist or not. We also plan on examining their responses to the perfectionism scales included in our survey to support their identification (or not) as a perfectionist. Qualitative analysis will begin once the first round of interviews has been completed.
