description: Convection is a fundamental fluid transport phenomenon, where the large-scale motion of a fluid is driven, for example, by a thermal gradient or an electric potential. Modeling convection has given rise to the development of chaos theory and the reduced-order modeling of multiphysics systems; however, these models have been limited to relatively simple thermal convection phenomena. In this work, we develop a reduced-order model for chaotic electroconvection at high electric Rayleigh number. The chaos in this system is related to the standard Lorenz model obtained from Rayleigh-Benard convection, although our system is driven by a more complex three-way coupling between the fluid, the charge density, and the electric field. Coherent structures are extracted from temporally and spatially resolved charge density fields via proper orthogonal decomposition (POD). A nonlinear model is then developed for the chaotic time evolution of these coherent structures using the sparse identification of nonlinear dynamics (SINDy) algorithm, constrained to preserve the symmetries observed in the original system. The resulting model exhibits the dominant chaotic dynamics of the original high-dimensional system, capturing the essential nonlinear interactions with a simple reduced-order model.

description: Η παρούσα εργασία αφορά την κριτική που κάνει ο Κάντ στη μεταφυσική, στο έργο του "Κριτική του καθαρού Λόγου". Πιο αναλυτικά, εξετάζουμε το πως ο ανθρώπινος λόγος οδηγείται σε παραλογισμού που αφορούν στην ψυχή, αντινομίες που αφορούν στον κόσμο και στην κενή έννοια του Θεού, όταν αφήνεται να οδηγηθεί πέρα από το πεδίο της δυνατής μας εμπειρίας
description: The following text concerns Kants critique of metaphysics as it appears on his book "Critique of pure reason". In more details, we examine how human reason leads, itself to paralogism concerning our soul, antinomies concerning the world and the empty idea of God, when it stretches itself beyond our realm of possible experience

description: We present and experimentally demonstrate a novel optical nondestructive controlled-NOT gate without using entangled ancilla. With much fewer measurements compared with quantum process tomography, we get a good estimation of the gate fidelity. The result shows a great improvement compared with previous experiments. Moreover, we also show that quantum parallelism is achieved in our gate and the performance of the gate can not be reproduced by local operations and classical communications.

Enhancing science teaching in an elementary school : a case study of a school-initiated teacher professional development program
Creators: name: Brooks, Clare M.
Publisher: name: University of British Columbia
Year: 2009

description: This naturalistic case study documents a year long Teacher Professional Development Program (TPDP) initiated by an elementary school staff in British Columbia. The TPDP was designed to enable the teachers to meet their objective of making science instruction more frequent, more active, and more student-centered in all classrooms in the school. This case study addresses two research questions: 1. What attributes of the Teacher Professional Development Program supported the school's "objective" for improved science instruction? 2. How did the outcomes of the Teacher Professional Development Program relate to the achievement of the school's educational objective? The site for the research was a kindergarten - Grade 7 school. A university professor and the researcher were invited to visit the school on a bi-weekly basis during one school year (1993-94) to facilitate a series of science workshops involving the entire teaching staff and to provide classroom support to teachers. Teachers were offered university course credit for their participation. This case study draws on qualitative data including: audio recordings of planning/debriefing sessions, workshop discussions, and interviews with participants; field notes and written observations; a survey of teachers' opinions about the TPDP; and documents relating to the school accreditation process in 1994-95. The results of the study show that teachers, administrators, and parents were satisfied that the school's objective for science instruction was met, and that the TPDP contributed significantly to this outcome. The study identifies TPDP attributes which supported the school's objective with reference to the teachers and their context, the planning process, and the organizational context, that is, the school. This study contributes to our understanding of teacher professional development by examining an alternative to more common approaches to elementary teacher science inservice in British Columbia, which are typically short-term, designed by inservice providers with little input from participants, and removed physically and conceptually from the classroom. Such inservice experiences often lack administrative and collegial support for the teacher who attempts classroom implementation. While this study relates to science, the discussion is relevant to other curriculum areas such as fine arts or physical education.

description: The objectives of this study were to examine current criteria and procedures used for setting speed limits on public roads and to recommend appropriate maximum speed limits for various types of roads. The study involved three major areas. These were: review of literature, collection and analysis of speed data, and collection and analysis of accident data. The speed data included collecting data on various highway types using the “moving” radar mode, use of data from speed monitoring stations, comparison of spot speed data before and after speed limit changes, and both moving and spot speed data at construction zones. Accident data were collected at locations where speed limits were changed and also on sections of adjacent interstates with different speed limits.  A recommendation is that the 85th percentile speed should be used as the standard method to establish speed limits. The speed limit should be posted in 5 mph increments and should be obtained by rounding the 85th percentile speed down to the nearest speed value in miles per hour that end in 5 or 0. The posted speed limit may be set at a speed where the minimum design speed for an entire road may allow the design speed for a specific location to be less than the speed limit. In those instances, advisory speed signs may be used to warn drivers to reduce their speed to less than the posted speed limit. An exception to the use of the 85th percentile speed would be for legislatively mandated speed limits.  The speed data show that a large percentage of vehicle speeds exceed currently posted speed limits. The highest percentage exceeding the limit was on urban interstates and two-lane parkways where the speed limit was 55 mph. The speeds for trucks were slightly less that for cars on all types of highways with a difference of less than 5 mph when the 85th percentile speed is considered.  A comparison of speed data at locations where speed limits were changed showed differences but not dramatic changes. The data support the theory that drivers will drive what they consider an appropriate speed regardless of the speed limit. A comparison of accident rates at adjacent sections of interstate where the speed limit was 55 and 65 mph did not find a substantial difference in the total, injury, or fatal accident rates.  Maximum speed limits are given for various type s of roads. In many instances, different limits are given for cars and trucks. The speed limit for a specific location would be based on an engineering study which would consider such factors as operating speed, design speed, roadway design elements, roadside appurtenances and obstacles, operational features, and an accident analysis. Statewide maximum speed limits of 70 mph for cars and 65 mph for trucks are recommended as well as 35 mph in business or residential areas.

description: We propose to dynamically control the conductivity of a Josephson junction composed of two weakly coupled one dimensional condensates of ultracold atoms. A current is induced by a periodically modulated potential difference between the condensates, giving access to the conductivity of the junction. By using parametric driving of the tunneling energy, we demonstrate that the low-frequency conductivity of the junction can be enhanced or suppressed, depending on the choice of the driving frequency. The experimental realization of this proposal provides a quantum simulation of optically enhanced superconductivity in pump-probe experiments of high temperature superconductors.

description: This report includes an analysis of traffic accident data in Kentucky for the years of 1992 through 1996. A primary objective of this study was to determine average accident statistics for Kentucky highways. Average and critical numbers and rates of accidents were calculated for various types of highways in rural and urban areas. These data can be used in Kentucky's procedure to identify locations that have abnormal rates or numbers of accidents.  The other primary objective of this study was to provide data which can be used in the preparation of the problem identification portion of Kentucky's Annual Highway Safety Plan. County and city accident statistics were analyzed. A summary of results and recommendations in several problem identification areas is presented. These general areas include alcohol involvement, occupant protection, speed, teenage drivers, pedestrians, bicycles, motorcycles, trains, and vehicle defects. Other areas included in the analysis are drug involvement, school bus accidents, and truck accidents.
$τ^{9}$ Eri: A bright pulsating magnetic Bp star in a 5.95-day double-lined spectroscopic binary

description: $τ^{9}$ Eri is a Bp star that was previously reported to be a single-lined spectroscopic binary. Using 17 ESPaDOnS spectropolarimetric (Stokes $V$) observations we identified the weak spectral lines of the secondary component and detected a strong magnetic field in the primary. We performed orbital analysis of the radial velocities of both components to find a slightly eccentric orbit ($e= 0.129$) with a period of $5.95382(2)$ days. The longitudinal magnetic field ($B_\ell$) of the primary was measured from each of the Stokes $V$ profiles, with typical error bars smaller than 10 G. Equivalent widths (EWs) of LSD profiles corresponding to only the Fe lines were also measured. We performed frequency analysis of both the $B_\ell$ and EW measurements, as well as of the Hipparcos, SMEI, and TESS photometric data. All sets of photometric observations produce two clear, strong candidates for the rotation period of the Bp star: 1.21 days and 3.82 days. The $B_\ell$ and EW measurements are consistent with only the 3.82-day period. We conclude that HD 25267 consists of a late-type Bp star (M= $3.6_{-0.2}^{+0.1} M_\odot$, T= $12580_{-120}^{+150}$ K) with a rotation period of 3.82262(4) days orbiting with a period of 5.95382(2) days with a late-A/early-F type secondary companion (M= $1.6\pm 0.1 M_\odot$, T= $7530_{-510}^{+580}$ K). The Bp star's magnetic field is approximately dipolar with $i= 41\pm 2^{\circ}$, $β= 158\pm 5^{\circ}$ and $B_{\rm d}= 1040\pm 50$ G. All evidence points to the strong $1.209912(3)$ day period detected in photometry, along with several other weaker photometric signals, as arising from $g$-mode pulsations in the primary.

description: The accretion of test fluids flowing onto a black hole is investigated. Particularly, by adopting a dynamical Hamiltonian approach, we are capable to find the critical points for various cases of black hole in conformal gravity. In these cases, we have analyzed the general solutions of accretion employing the isothermal equations of state. The steady state and spherically symmetric accretion of different test fluids onto the conformal gravity black hole has been considered. Further, we have classified these flows in the context of equations of state and the cases of conformal gravity black hole. The new behavior of polytropic fluid accretion is also discussed in all three cases of black hole. Black hole mass accretion rate is the most important part of this research in which we have investigated that the Schwarzschild black hole produce a typical signature than the conformal gravity black hole and Schwarzschild de-Sitter black hole. The critical fluid flow and the mass accretion rate have been presented graphically by the impact parameters $β$, $γ$, $k$ and these parameters have great significance. Additionally, the maximum mass rate of accretion fall near the universal and Killing horizons and minimum rate of accretion occurs in between these regions. Finally, the results are compared with the different cases of black hole available in the literature.

The Hong Kong and British Columbia art curriculum guides: a comparative study
Creators: name: Gleckman, Brian Keith
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is a comparative study which examines the formal art curriculum guides of Hong Kong and British Columbia. The rationale for this study lies, in part, with the documented demographic change that has taken place in British Columbia schools over the past decade, in particular, the significant numbers of Hong Kong immigrant students who have enrolled in four of British Columbia's five largest school districts. The study examines the Hong Kong and British Columbia education systems overall, places the art curriculum for each jurisdiction in respective context, and surveys the content of the guides themselves. The study then examines in comparative fashion the guides with regard to general content of the guides, conceptual frameworks for the curriculum, the presentation of expected learning outcomes, curricular content, and assessment and evaluation. The findings within these topics are summarized in terms of similarities and differences. The findings are also analyzed relative to traditional Chinese conceptions of education and the extent to which they reflect the histories and traditions of art education in Hong Kong. The curriculum guides are also analyzed according to the three conceptual orientations of curriculum posited by Miller and Seller: transmissional, transactional, and transformational. The thesis finds that while there are a number of similarities between the art curriculum guides of Hong Kong and British Columbia, the differences between the two sets of documents are significant in terms of 1) how art curriculum is conceptualized, 2) implied expectations with regard to teaching and learning styles, and 3) the specificity of curricular content. The thesis also suggests that the Hong Kong art curriculum guides reflect a transmissional orientation to curriculum, while the British Columbia guides reflect a transformational, if not transactional orientation. The thesis concludes by pointing to the need for comparative observation of art education in Hong Kong and British Columbia in order to more concretely identify the similarity or differences in the actual art educational experiences of students within each jurisdiction.
Evaluation of the ET2000 Guardrail End Treatment

description: The objectives of this study were to monitor and report the performance of the ET2000 guardrail end treatment design in traffic accidents. Data for a total of 34 collisions involving the ET2000 were identified. In most cases, an accident report was obtained and the damaged guardrail was inspected. The involved vehicle was inspected when available. Proper or improper performance of end treatments in the collisions were judged based on whether it performed as designed.  Field performance of the ET2000, as documented in traffic accidents, shows that, considering all the impacts, this end treatment has performed properly. In several instances the end treatment bent, rather than being pushed straight back, during the collision. This could typically be related to the angle at which impact occurred. Results warrant continued use of this end treatment. However, its cost would not justify a widespread use on all types of highways.

description: The idea that structural disorder might be a novel mechanism of protein interaction is widespread in the Literature, although the number of statistically significant structural studies supporting this is surprisingly low. At variance with previous works, our conclusions rely exclusively on a large-scale analysis of all the 134337 X-ray crystallographic structures of the Protein Data Bank averaged over clusters of almost identical protein sequences. In this work, we explore the complexity of the organization of all the interaction interfaces observed when a protein lies in alternative complexes, showing that interfaces progressively add up in a hierarchical way. We further investigate the connection of this complexity with different measures of structural disorder: the standard missing residues and a new definition, called "soft disorder", that covers all the flexible and structurally amorphous residues of a protein. We show evidences that both the interaction interfaces and the soft disordered regions tend to involve roughly the same amino-acids of the protein, and preliminary results suggesting that soft disorder spots those surface regions where new interfaces are progressively accommodated by complex formation. Our results suggest that disordered regions not only carry crucial information about the location of alternative interfaces within complexes, but also of the order of the assembly. We verify these hypotheses in several examples. We finally compare our measures of disorder with several disorder predictors, showing that these latter are optimized to predict the residues that are missing in all the alternative structures of a protein, and they are not able to catch the progressive evolution of the disordered regions upon complex formation. Yet, the predicted residues, if not missing, tend to be characterized as soft disordered.

description: LOFAR (Low Frequency Array) is an innovative radio telescope optimized for the frequency range 30-240 MHz. The telescope is realized as a phased aperture array without any moving parts. Digital beam forming allows the telescope to point to any part of the sky within a second. Transient buffering makes retrospective imaging of explosive short-term events possible. The scientific focus of LOFAR will initially be on four key science projects (KSPs): 1) detection of the formation of the very first stars and galaxies in the universe during the so-called epoch of reionization by measuring the power spectrum of the neutral hydrogen 21-cm line (Shaver et al. 1999) on the ~5' scale; 2) low-frequency surveys of the sky with of order $10^8$ expected new sources; 3) all-sky monitoring and detection of transient radio sources such as gamma-ray bursts, x-ray binaries, and exo-planets (Farrell et al. 2004); and 4) radio detection of ultra-high energy cosmic rays and neutrinos (Falcke & Gorham 2003) allowing for the first time access to particles beyond 10^21 eV (Scholten et al. 2006). Apart from the KSPs open access for smaller projects is also planned. Here we give a brief description of the telescope.

description: We perform calculations for ωproduction in nuclei by means of the (γ,p) reaction for photon energies and proton angles suited to running and future experiments in present Laboratories. For some cases of possible ωoptical potentials we find clear peaks which could be observable provided a good resolution in the ωenergy is available. We also study the inclusive production of π^0 γin nuclei around the ωenergy and find a double hump structure for the energy spectra, with a peak around a π^0 γenergy of m_ω-100 MeV, which could easily be misidentified by a signal of a bound ωstate in nuclei, while it is due to a different scaling of the uncorrelated π^0 γproduction and ωproduction with subsequent π^0 γdecay.

description: The EXperiment for Cryogenic Large-Aperture Intensity Mapping (EXCLAIM) is a balloon-borne far-infrared telescope that will survey star formation history over cosmological time scales to improve our understanding of why the star formation rate declined at redshift z < 2, despite continued clustering of dark matter. Specifically,EXCLAIM will map the emission of redshifted carbon monoxide and singly-ionized carbon lines in windows over a redshift range 0 < z < 3.5, following an innovative approach known as intensity mapping. Intensity mapping measures the statistics of brightness fluctuations of cumulative line emissions instead of detecting individual galaxies, thus enabling a blind, complete census of the emitting gas. To detect this emission unambiguously, EXCLAIM will cross-correlate with a spectroscopic galaxy catalog. The EXCLAIM mission uses a cryogenic design to cool the telescope optics to approximately 1.7 K. The telescope features a 90-cm primary mirror to probe spatial scales on the sky from the linear regime up to shot noise-dominated scales. The telescope optical elements couple to six μ-Spec spectrometer modules, operating over a 420-540 GHz frequency band with a spectral resolution of 512 and featuring microwave kinetic inductance detectors. A Radio Frequency System-on-Chip (RFSoC) reads out the detectors in the baseline design. The cryogenic telescope and the sensitive detectors allow EXCLAIM to reach high sensitivity in spectral windows of low emission in the upper atmosphere. Here, an overview of the mission design and development status since the start of the EXCLAIM project in early 2019 is presented.

description: Το θέμα της διατριβής αυτής είναι η ανάλυση δεδομένων αναλογιών και η εφαρμογή των δεδομένων αυτών στον καθορισμό απαιτήσεων για την ποιότητα λογισμικού. Συγκεκριμένα, τα δεδομένα αναλογιών αποτελούνται από διανύσματα τα στοιχεία των οποίων είναι περιεκτικότητες ή αναλογίες ενός ευρύτερου συνόλου. Η ιδιαιτερότητά τους έγκειται στο ότι το άθροισμά τους υπόκειται στον περιορισμό μιας σταθεράς, ίσης με τη μονάδα για περιεκτικότητες, ή ίσης με 100 για ποσοστά. Μεταξύ αναλογιών των οποίων οι αριθμητές και παρονομαστές περιέχουν κοινά τμήματα, εμφανίζονται πλαστές συσχετίσεις και συνεπώς, δεν είναι εφαρμόσιμη η κλασσική πολυμεταβλητή ανάλυση. Σκοπός της διατριβής είναι να ερευνηθεί η φύση των δεδομένων αναλογιών και να αναλυθούν πραγματικά δεδομένα τέτοιου τύπου με τα κατάλληλα προγράμματα. Αρχικά, στο πρώτο τμήμα της διατριβής αυτής γίνεται μελέτη της βιβλιογραφίας που αφορά βασικές έννοιες και ορισμούς των δεδομένων αναλογιών. Στη συνέχεια, αναλύονται οι μέθοδοι επεξεργασίας, οι θεμελιώδεις πράξεις των δεδομένων αναλογιών και οι τρεις μετασχηματισμοί λογαριθμημένων λόγων. Στο δεύτερο τμήμα της διατριβής γίνεται περιγραφή του σχετικού προγράμματος Codapack και παρουσιάζεται αναλυτικά η πρακτική εφαρμογή όλων των δυνατοτήτων του προγράμματος αυτού σε δεδομένα από ερωτηματολόγια ιεράρχησης απαιτήσεων λογισμικού. Τέλος, με τη βοήθεια του προγράμματος SPSS, γίνεται πλήρης ανάλυση των μετασχηματισμένων δεδομένων που προέκυψαν απ’ το Codapack και συνάγονται τα αντίστοιχα συμπεράσματα
description: The subject of this thesis is compositional data analysis and application in requirements prioritization for software’s quality. Specifically, compositional data consist of vectors whose components are proportions or percentages of some whole. Their peculiarity is that their sum is constrained to be some constant, equal to 1 for proportions or equal to 100 for percentages. As between ratios whose numerators and denominators contain common parts arise spurious correlations, classical multivariate analysis is not applicable. This thesis aims to research compositional data nature and analyze real compositional data with the corresponding packages, as well. First, a survey of the related literature is presented that studies basic concepts and definitions. Next, process methods, fundamental operations and logratio transformations are discussed. In the second part of this thesis, Codapack software package is presented elaborately and is applied to compositional data derived from software requirements prioritization questionnaires. Finally, SPSS software is used in order to analyze in depth the Codapack transformed data.
Giant X-ray and optical Bump in GRBs: evidence for fall-back accretion model

description: The successful operation of dedicated detectors has brought us valuable information for understanding the central engine and the progenitor of gamma-ray bursts (GRBs). For instance, the giant X-ray and optical bumps found in some long-duration GRBs (e.g. GRBs 121027A and 111209A) imply that some extended central engine activities, such as the late X-ray flares, are likely due to the fall-back of progenitor envelope materials. Here we systemically search for long GRBs that consist of a giant X-ray or optical bump from the Swift GRB sample, and eventually we find 19 new possible candidates. The fall-back accretion model could well interpret the X-ray and optical bump for all candidates within a reasonable parameter space. Six candidates showing simultaneous bump signatures in both X-ray and optical observations, which could be well fitted at the same time when scaling down the X-ray flux into optical by one order of magnitude, are consistent with the standard $F_ν\proptoν^{1/3}$ synchrotron spectrum. The typical fall-back radius is distributed around $10^{10}\rm-10^{12}$ cm, which is consistent with the typical radius of a Wolf-Rayet star. The peak fall-back accretion rate is in the range of $\sim 10^{-11}-10^{-4}M_{\odot} \ \text{s} ^{-1}$ at time $\sim10^{2}- 10^{5}~\rm s$, which is relatively easy to fulfill as long as the progenitor's metallicity is not too high. Combined with the sample we found, future studies of the mass supply rate for the progenitors with different mass, metallicity, and angular momentum distribution would help us to better constrain the progenitor properties of long GRBs.

description: Magellanic Bridge C (MB-C) is a metal-poor ($\sim$1/5 $Z_{\odot}$) low-density star-forming region located 59 kpc away in the Magellanic Bridge, offering a resolved view of the star formation process in conditions different to the Galaxy. From Atacama Large Millimetre Array CO (1-0) observations, we detect molecular clumps associated to candidate young stellar objects (YSOs), pre-main sequence (PMS) stars, and filamentary structure identified in far-infrared imaging. YSOs and PMS stars form in molecular gas having densities between 17-200 $M_{\odot}$ pc$^{-2}$, and have ages between $\lesssim$0.1-3 Myr. YSO candidates in MB-C have lower extinction than their Galactic counterparts. Otherwise, our results suggest that the properties and morphologies of molecular clumps, YSOs, and PMS stars in MB-C present no patent differences with respect to their Galactic counterparts, tentatively alluding that the bottleneck to forming stars in regions similar to MB-C is the conversion of atomic gas to molecular.

BAYES-LOSVD: a bayesian framework for non-parametric extraction of the line-of-sight velocity distribution of galaxies

Year: 2020
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We introduce BAYES-LOSVD, a novel implementation of the non-parametric extraction of line-of-sight velocity distributions (LOSVDs) in galaxies. We employ bayesian inference to obtain robust LOSVDs and associated uncertainties. Our method relies on principal component analysis to reduce the dimensionality of the base of templates required for the extraction and thus increase the performance of the code. In addition, we implement several options to regularise the output solutions. Our tests, conducted on mock spectra, confirm the ability of our approach to model a wide range of LOSVD shapes, overcoming limitations of the most widely used parametric methods (e.g. Gauss-Hermite expansion). We present examples of LOSVD extractions for real galaxies with known peculiar LOSVD shapes, i.e. NGC4371, IC0719 and NGC4550, using MUSE and SAURON integral-field unit (IFU) data. Our implementation can also handle data from other popular IFU surveys (e.g. ATLAS3D, CALIFA, MaNGA, SAMI). Details of the code and relevant documentation are freely available to the community in the dedicated repositories.

This is a direct consequence of a representation of such sets as supports of positive closed currents.

description: GdBa$_2$Cu$_3$O$_{7-δ}$ (GdBCO) is a promising high-temperature superconductor with potential application as coated conductor for power applications (e.g. transformers). However, further improvements in cost-effectiveness and superconducting properties are desired. The latter are influenced by O content, film texture, and film quality, where non-superconducting defects can effectively pin magnetic flux lines if they have favorable shape, size, and density. The O content in GdBCO can be set in-situ after film deposition or afterward by annealing in a different furnace (ex-situ). The correlation of oxygenation processes and defect formation/healing in GdBCO is not fully understood. In this work, we apply scanning transmission electron microscopy (STEM) to investigate the effect of different ex-situ oxygenation routes on the GdBCO microstructure.

description: We develop a renormalized perturbation theory for the dynamics of interacting Brownian particles, which preserves the fluctuation-dissipation relation order by order. We then show that the resulting one-loop theory gives a closed equation for the density correlation function, which is identical with that in the standard mode coupling theory.

description: Bad statistics make research papers unreproducible and misleading. For the most part, the reasons for such misusage of numerical data have been found and addressed years ago by experts and proper practical solutions have been presented instead. Yet, we still see numerous instances of statistical fallacies in modern researches which without a doubt play a significant role in the research reproducibility crisis. In this paper, we review different bad practices that impact the research process from its beginning to its very end. Additionally, we briefly propose open science as a universal methodology that can facilitate the entire research life cycle.
