description: The problem of structure formation in relativistic dissipative fluids was analyzed in a previous work within Eckart's framework, in which the heat flux is coupled to the hydrodynamic acceleration, additional to the usual temperature gradient term. It was shown that in such case, the pathological behavior of fluctuations leads to the disapperance of the gravitational instability responsible for structure formation. In the present work the problem is revisited now using a constitutive equation derived from relativistic kinetic theory. The new relation, in which the heat flux is not coupled to the hydrodynamic acceleration, leads to a consistent first order in the gradients formalism. In this case the gravitational instability remains, and only relativistic corrections to the Jeans wave number are obtained. In the calculation here shown the non-relativistc limit is recovered, opposite to what happens in Eckart's case.

description: Research into connotative frames of reference using the semantic differential has been undertaken in various cultures. The present study examined semantic space and attitudinal dimensions among negro and white students in Nova Scotia by means of factor analysis. Three hundred and eighty-one students between the ages 13 to 16 wrote a semantic differential test comprising fifteen concepts and twenty-one scales. Programs were written to permit analysis of the data by computer. Factor analysis of the semantic differential scales yielded three factors of semantic space, comparable to those found by Osgood (1957) and others: Evaluative, Dynamism, and Activity. However, the scales weak--strong, powerful--powerless, fast--slow, and quiet--noisy loaded uniquely on the Evaluative dimension in this study. Six factors were found to delineate the attitudinal space of each of the four sub-groups. These factors varied for each group and indicated race and sex differences. White males placed the future as their prime concern, whereas security was most important for the white female sample. The male and female negro samples both placed personal identity as their main concern. The white female sample indicated a poor self- concept. Schools and teachers seemed to have unpleasant associations for both the white samples. White males perceived negroes as both a friend and an enemy. The white female sample made no distinction between the races. Both the negro groups appeared to view the white population as a threat to their success. The study lent some support to Osgood's theory of the universality of semantic space, particularly the Evaluative dimension.

On the causal characterization of singularities in spherically symmetric spacetimes

Year: 2012
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The causal character of the zero-areal-radius (R=0) singularity in spherically symmetric spacetimes is studied. By using the techniques of the qualitative behaviour of dynamic systems, we are able to present the most comprehensive scheme so far to try to find out their causal characterization, taking into account and analyzing, the possible limitations of the approach. We show that, with this approach, the knowledge of the scalar invariant $m\equiv R(1-g^{μν}\partial_μR\partial_νR)/2$ suffices to characterize the singularity. We apply our results to the study of the outcome of Black Hole evaporation and show different possibilities. In this way, we find that a persistent naked singularity could develop in the final stages of the evaporation and we show its distinctive features. Likewise, we study the options for the generation of naked singularities in the collapse of an object (such as a star) as a means of violating the cosmic censorship conjecture.

description: Ein Modell wird vorgestellt, welches den vielfältig parametrisierten Verlauf speziell von Geschäftsreisen inklusive Schlaf- und Arbeitszeiten simuliert. Die motivierende Forschungsfrage ist die nach dem zeitlichen Nutzen von Hochgeschwindigkeitsflug für den einzelnen Passagier. Es wird angenommen, dass ein Zeitgewinn auf einer Reise neben einer kürzeren Dauer auch durch Bewahrung produktiver (Arbeits-)Zeit sowie durch Sicherstellung von Ausgeruhtheit erzielt wird. Diese drei Zielgrößen werden in dem Kennwert der „Zeit-Kosten einer Reise“ vereinigt. Die Modellierung von Dauern und Zeitpunkten des Schlafs stellt eine Hauptschwierigkeit der Arbeit dar. Die grundsätzliche Validität der Algorithmen wird anhand dokumentierter realer Reiseabläufe nachgewiesen. In einem ersten Anwendungsfall werden für einen Reisenden optimale Flugverbindungen ausgesucht. Ein zweiter vergleicht weltweite Reisen von Unterschall- mit denen von Überschall-Businessjets.
description: A model simulates the diversely parameterized progress of dedicated business journeys including sleep and working times. The motivating research question asks for the benefit of high speed flight regarding time. It is assumed that on journeys, time gains are not only achieved by shorter travel, but also by retaining productive (working) time as well as by securing restedness. Those three target values are joined into the parameter of “time cost of travel”. Modelling durations and timings of sleep poses a main difficulty for this work. The algorithms’ basic validity is demonstrated by comparisons to actual documented journeys. An initial use-case selects optimum flight connections for a traveler. A second use-case compares world-wide travel in a subsonic business jet to a supersonic counterpart.

description: Bibliography: p. 110-114.
description: This thesis demonstrates that Fowles's traditional view of the nature and function of characters in the novel, as revealed through his creation of characters in The French Lieutenant's Woman, results in a novel in which the reader's emotional response and his aesthetic response are united in his response to the characters. He responds emotionally because the characters are interesting in their variety and their representativeness of their age while several of the major figures are also individualized and revealed through emotionally intense situations. He responds aesthetically because the interactions of these characters constitute a basis of the form of the novel. Both responses are united in the reaction to the narrator as a character who shares several of his qualities with the other personages but who also gives form and substance to the others and to the novel. Although it is beyond the scope of this thesis to argue that Fowles's success in creating characters through traditional methods marks a return to belief in the significance of the individual character generally upheld in nineteenth century fiction, it is suggested that because of Fowles's success it is not possible to regard the expunging of the individual as one of the inexorable tendencies of modem fiction.

WR 38/38a and the ratio of total-to-selective extinction in Carina

description: A reanalysis of the (seemingly very distant) open cluster Shorlin 1, the group of stars associated with WR 38 and WR 38a, is made on the basis of existing UBV and JHKs observations for cluster members. The 2MASS observations, in particular, imply a mean cluster reddening of E(B-V)=1.45+-0.07 and a distance of 2.94+-0.12 kpc. The reddening agrees with the UBV results provided that the local reddening slope is described by E(U-B)/E(B-V)=0.64+-0.01, but the distance estimates in the 2MASS and UBV systems agree only if the ratio of total-to-selective extinction for the associated dust is R=Av/E(B-V)=4.0+-0.1. Both results are similar to what has been obtained for adjacent clusters in the Eta Carinae region by similar analyses, which suggests that `anomalous' dust extinction is widespread through the region, particularly for groups reddened by relatively nearby dust. Dust associated with the Eta Carinae complex itself appears to exhibit more `normal' qualities. The results have direct implications for the interpretation of distances to optical spiral arm indicators for the Galaxy at l=287-291 degrees, in particular the Carina arm here is probably little more than ~2 kpc distant, rather than 2.5-3 kpc distant as implied in previous studies. Newly-derived intrinsic parameters for the two cluster Wolf-Rayet stars WR 38 (WC4) and WR 38a (WN5) are in good agreement with what is found for other WR stars in Galactic open clusters, which was not the case previously.

description: The photoproduction of pion off nucleon is investigated within a dynamical coupled-channels approach based on the Juelich pi-N model, which has been quite successful in the description of pi-N to pi-N scattering for center-of-mass energies up to 1.9 GeV. The full pion photoproduction amplitude is constructed to satisfy the generalized Ward-Takahashi identity and hence, it is fully gauge invariant. The calculated differential cross sections and photon spin asymmetries up to 1.65 GeV center-of-mass energy for the reactions gamma p to pi^+ n, gamma p to pi^0 p and gamma n to pi^- p are in good agreement with the experimental data.

Gravitational wave energy momentum-tensor in reduced Horndeski theories

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We generalize, imposing the field equations only at dominant order, the Isaacson formula for the gravitational wave (GW) energy-momentum tensor (EMT) to the class of Horndeski theories in which the tensor modes travel at the speed of light (reduced Horndeski theories) and scalar waves are present. We discuss important particular cases such as: theories where scalar waves are also luminal and theories in which the transverse-traceless gauge can be achieved in an arbitrary open set. The vanishing of the trace of the gravitational wave energy-momentum tensor is obtained for theories in which all wave perturbations propagate at the speed of light. The trace is shown not to vanish trivially in other cases. We obtain, as a particular case of our general result, the GW EMTs, in a Brans-Dicke theory, both in the Einstein frame, recovering previous results in the literature, and in the Jordan frame, thereby showing the GW EMT is not conformally invariant. We further prove that there exists a subclass of reduced Horndeski theories where, in contrast to general relativity, the divergence of the GW EMT does not vanish even after the imposition of the full equations of motion, assuming an eikonal solution.

We derived, from first principles, extended Hubbard models for twelve compounds; fcc K3C60, Rb3C60, Cs3C60 (with three different lattice constants), A15 Cs3C60 (with four different lattice constants), doped solid picene, coronene, and phenanthrene. We show that these compounds are strongly correlated and have a similar energy scale of the bandwidth and interaction parameters. However, they have a different trend in the relation between the strength of electronic correlation and superconducting transition temperature; while the C60 compounds have a positive correlation, the aromatic compounds exhibit negative correlation.

Digital literacy and teacher education in Uganda : the case of Bondo Primary Teachers' College (PTC)
Creators: name: Andema, Samuel
Publisher: name: University of British Columbia
Year: 2009

description: Claims about the potential of Information and Communication Technology (ICT) to transform education in the less developed countries of the world abound. This qualitative case study, which took place at Bondo (pseudonym) Primary Teachers’ College (PTC) in Uganda, from April to December 2008, was guided by two specific research questions, (1) What is the relationship between ICT policy and educational practice in Uganda? (2) To what extent do teacher educators use ICT in their professional practice and what challenges do they face in developing digital literacy? To address question one, the researcher did a content analysis of the National ICT policies and held a key informant interview with the ICT minister in Uganda. In order to address question two, the researcher drew on data collected from a sample of six teacher educators using questionnaires, focus group discussions, online group discussions, and journal reflections. The study found that at policy level, Uganda has made significant progress in systematizing the integration of ICT in education. The introduction of ICT training programs in PTCs has received positive response from the teacher educators, who are eager to use ICT in their professional practice and to develop their digital literacy skills. However, the study established that the teacher educators only use ICT in their professional practice to a limited extent, due to factors such as limited Internet access points at the PTC and in their communities. Other challenges include inadequate training and lack of support for professional development, cultural constraints, and irrelevant materials from the Internet. Another major concern is that ICT initiatives in Uganda are geared more towards accessing global information than using ICT for knowledge production and wealth creation. It also emerged that ICT is still being used to perpetuate teacher-centered, examination-oriented, information-based teaching and learning in PTCs. The study concludes with a recommendation for more qualitative case studies on the possibility of incorporating ICT programs such as the e-Granary Digital Library, which do not rely on connectivity, as a basis for ICT and digital literacy skills development.

As an application of this formalism, we construct the Kalb-Ramond term for supersymmetric sigma models on the supersphere.

description: Using H-alpha emission as a tracer of on-going (<16 Myr old) and near-UV emission as a tracer of recent (16-100 Myr old) star formation (SF), we present constraints on core-collapse (CC) supernova (SN) progenitors through their association with SF regions. We present statistics of a large sample of SNe; 163.5 type II (58 IIP, 13 IIL, 13.5 IIb, 19 IIn and 12 'impostors') and 96.5 type Ib/c (39.5 Ib and 52 Ic). Using pixel statistics our main findings and conclusions are: 1) An increasing progenitor mass sequence is observed, implied from an increasing association of SNe to host galaxy H-alpha emission. This commences with the type Ia (SNIa) showing the weakest association, followed by the SNII, then the SNIb, with the SNIc showing the strongest correlation to SF regions. Thus our progenitor mass sequence runs Ia-II-Ib-Ic. 2) Overall SNIbc are found to occur nearer to bright HII regions than SNII. This implies that the former have shorter stellar lifetimes thus arising from more massive progenitor stars. 3) While SNIIP do not closely follow the on-going SF, they accurately trace the recent formation. This implies that their progenitors arise from stars at the low end of the CC SN mass sequence, consistent with direct detections of progenitors in pre-explosion imaging. 4) Similarly SNIIn trace recent but not the on-going SF. This implies that, contrary to the general consensus, the majority of these SNe do not arise from the most massive stars. Results and constraints are also presented for the less numerous SNIIL, IIb, and 'impostors'. Finally we present analysis of possible biases in the data, the results of which argue strongly against any selection effects that could explain the relative excess of SNIbc within bright HII regions. Thus intrinsic progenitor differences in the sense of the mass sequence we propose remain the most plausible explanation of our findings.

Protostellar outbursts : which chemistry for the envelope ?
Creators: name: Marchand, Pierre

Publisher: name: Zenodo
Year: 2023

description: Episodic accretion in protostars may trigger luminosity outbursts, and therefore heat up their envelope. The sudden increase of temperature sublimates ice mantles on grains, and the release of new molecules in the gas phase may alter the long-term evolution of the chemical environment. In this study, we investigate the chemical composition of the envelope of an outbursting protostar, by performing a spectral survey with the IRAM-30m telescope, and by applying kinetic chemical models to protostellar envelope simulations.

description: The static dependency pair method is a method for proving the termination of higher-order rewrite systems a la Nipkow. It combines the dependency pair method introduced for first-order rewrite systems with the notion of strong computability introduced for typed lambda-calculi. Argument filterings and usable rules are two important methods of the dependency pair framework used by current state-of-the-art first-order automated termination provers. In this paper, we extend the class of higher-order systems on which the static dependency pair method can be applied. Then, we extend argument filterings and usable rules to higher-order rewriting, hence providing the basis for a powerful automated termination prover for higher-order rewrite systems.

description: We study the odd-frequency Cooper pairs formed near the surface of superfluid 3He. The odd-frequency pair amplitude is closely related to the local density of states in the low energy limit. We derive a formula relating explicitly the two quantities. This formula holds for arbitrary boundary condition at the surface. We also present some numerical results on the surface odd-frequency pair amplitude in superfluid 3He-B. Those analytical and numerical results allow one to interpret the midgap surface density of states, observed recently by transverse acoustic impedance measurements on superfluid 3He-B, as the manifestation of the surface odd-frequency state.

description: We demonstrate the ultranarrow temporal correlation (6 fs full width half maximum) of twin beams generated by parametric down-conversion, by using the inverse process of sum-frequency generation. The result relies on an achromatic imaging of a huge bandwith of twin beams and on a careful control of their spatial degrees of freedom. The detrimental effects of spatial filtering and of imperfect imaging are shown toghether with the theoretical model used to describe the results.

description: The degrees of freedom of any interacting quantum field theory are entangled in momentum space. Thus, in the vacuum state, the infrared degrees of freedom are described by a density matrix with an entanglement entropy. We derive a relation between this density matrix and the conventional Wilsonian effective action. We argue that the entanglement entropy of and mutual information between subsets of field theoretic degrees of freedom at different momentum scales are natural observables in quantum field theory and demonstrate how to compute these in perturbation theory. The results may be understood heuristically based on the scale-dependence of the coupling strength and number of degrees of freedom. We measure the rate at which entanglement between degrees of freedom declines as their scales separate and suggest that this decay is related to the property of decoupling in quantum field theory.

description: Objective: This study compared radiographic measures of foot structure between people with and without symptomatic radiographic midfoot osteoarthritis (OA). Methods: This was a cross-sectional study of adults aged 50 years and older registered with four UK general practices who reported foot pain in the past year. Bilateral weightbearing dorsoplantar and lateral radiographs were obtained. Symptomatic radiographic midfoot OA was defined as midfoot pain in the last 4 weeks, combined with radiographic OA in one or more midfoot joints (first cuneometatarsal, second cuneometatarsal, navicular-first cuneiform, and talonavicular). Midfoot OA cases were matched 1:1 for sex and age to controls with a 5-year age tolerance. Eleven radiographic measures were extracted and compared between the groups using independent sample t-tests and effect sizes (Cohen's d). Results: We identified 63 midfoot OA cases (mean ± SD age was 66.8 ± 8.0 years, with 32 male and 31 female participants) and matched these to 63 controls (mean ± SD age was 65.9 ± 7.8 years). There were no differences in metatarsal lengths between the groups. However, those with midfoot OA had a higher calcaneal-first metatarsal angle (d = 0.43, small effect size, P = 0.018) and lower calcaneal inclination angle (d = 0.46, small effect size, P = 0.011) compared with controls. Conclusions: People with midfoot OA have a flatter foot posture compared with controls. Although caution is required when inferring causation from cross-sectional data, these findings are consistent with a pathomechanical pathway linking foot structure to the development of midfoot OA. Prospective studies are required to determine the temporal relationships between foot structure, function, and the development of this common and disabling condition.

description: Transformation elasticity, by analogy with transformation acoustics and optics, converts material domains without altering wave properties, thereby enabling cloaking and related effects. By noting the similarity between transformation elasticity and the theory of incremental motion superimposed on finite pre-strain it is shown that the constitutive parameters of transformation elasticity correspond to the density and moduli of small-on-large theory. The formal equivalence indicates that transformation elasticity can be achieved by selecting a particular finite (hyperelastic) strain energy function, which for isotropic elasticity is semilinear strain energy. The associated elastic transformation is restricted by the requirement of statically equilibrated pre-stress. This constraint can be cast as $\tr {\mathbf F} =$ constant, where $\mathbf{F}$ is the deformation gradient, subject to symmetry constraints, and its consequences are explored both analytically and through numerical examples of cloaking of anti-plane and in-plane wave motion.

description: Discrete microfluidics is the manipulation of independently controllable sample volumes of fluids in the form of drops. Superhydrophobic materials, with their excellent water repelling characteristic, self-cleaning and anti-fouling properties, are ideal for integration into microfluidic applications. This thesis presents studies on the behaviour of liquid drops when subjected to different forms of perturbations, coupled with superhydrophobic materials, to provide a deeper understanding of their mechanics and develop novel microfluidic applications.

description: The recently introduced compressive sensing (CS) framework enables digital signal acquisition systems to take advantage of signal structures beyond bandlimitedness. Indeed, the number of CS measurements required for stable reconstruction is closer to the order of the signal complexity than the Nyquist rate. To date, the CS theory has focused on real-valued measurements, but in practice, measurements are mapped to bits from a finite alphabet. Moreover, in many potential applications the total number of measurement bits is constrained, which suggests a tradeoff between the number of measurements and the number of bits per measurement. We study this situation in this paper and show that there exist two distinct regimes of operation that correspond to high/low signal-to-noise ratio (SNR). In the measurement compression (MC) regime, a high SNR favors acquiring fewer measurements with more bits per measurement; in the quantization compression (QC) regime, a low SNR favors acquiring more measurements with fewer bits per measurement. A surprise from our analysis and experiments is that in many practical applications it is better to operate in the QC regime, even acquiring as few as 1 bit per measurement.

description: Additive manufacturing provides high design flexibility, but its use is restricted by limited mechanical properties compared to conventional production methods. As technology is still emerging, several approaches exist in the literature for quantifying and improving mechanical properties. In this study, we investigate characterizing materials’ response of additive manufactured structures, specifically by fused deposition modeling (FDM). A comparative analysis is achieved for four different tensile test specimens for polymers based on ASTM D3039 and ISO 527-2 standards. Comparison of specimen geometries is studied with the aid of computations based on the Finite Element Method (FEM). Uniaxial tensile tests are carried out, after a careful examination of different slicing approaches for 3D printing. We emphasize the effects of the chosen slicer parameters on the position of failures in the specimens and propose a simple formalism for measuring effective mechanical properties of 3D-printed structures.

description: Lattice Boltmzmann Methods (LBM) have been proved to be very effective methods for computational aeroacoustics (CAA), which have been used to capture the dynamics of weak acoustic fluctuations. In this paper, we propose a strategy to reduce the dispersive and disspative errors of the two-dimensional (2D) multi-relaxation-time lattice Boltzmann method (MRT-LBM). By presenting an effective algorithm, we obtain a uniform form of the linearized Navier-Stokes equations corresponding to the MRT-LBM in wave-number space. Using the matrix perturbation theory and the equivalent modified equation approach for finite difference methods, we propose a class of minimization problems to optimize the free-parameters in the MRT-LBM. We obtain this way a dispersion-relation-preserving LBM (DRP-LBM) to circumvent the minimized dispersion error of the MRT-LBM. The dissipation relation precision is also improved.And the stability of the MRT-LBM with the small bulk viscosity is guaranteed. Von Neuman analysis of the linearized MRT-LBM is performed to validate the optimized dispersion/dissipation relations considering monochromatic wave solutions. Meanwhile, dispersion and dissipation errors of the optimized MRT-LBM are quantitatively compared with the original MRT-LBM . Finally, some numerical simulations are carried out to assess the new optimized MRT-LBM schemes.

description: We show that a two-mode three-level cascade laser driven by external coherent fields generate intense entangled light. It turns out that external driving fields which are at resonance with the cavity modes substantially improves the intensity of the two-mode light in the cavity in a region where the squeezing and entanglement is significant making the system under consideration a viable source of bright squeezed as well as entangled light.

Deformation and scattering in graphene over substrate steps

description: The electrical properties of graphene depend sensitively on the substrate. For example, recent measurements of epitaxial graphene on SiC show resistance arising from steps on the substrate. Here we calculate the deformation of graphene at substrate steps, and the resulting electrical resistance, over a wide range of step heights. The elastic deformations contribute only a very small resistance at the step. However, for graphene on SiC(0001) there is strong substrate-induced doping, and this is substantially reduced on the lower side of the step where graphene pulls away from the substrate. The resulting resistance explains the experimental measurements.

Outward location bias in selective perception

description: This study seeks to identify a dimension of outward location bias in visual selective perception, to develop valid measures of this bias, and to measure the extent to which this bias can be predicted by measures of field-independence, intelligence, and creativity. Persons demonstrating outward location bias are defined as those responding to relatively outwardly located visual cues in two-dimensional displays. The five tests developed require different types of responses, such as cancelling letters and checking-off lists of items after viewing slides. The sample consisted of 375 grade eight boys and girls in two Calgary junior high schools. The tests were found to be reliable. Four of them presented problems of interpretation, since the effects of responding to centrally or inwardly located cues were difficult to overcome. Their intercorrelations were low. A multivariate stepdown regression analysis permitted the conclusion that the scores on the test battery could be predicted from nonverbal measures of cognitive functioning, as hypothesized, though not for all the predictor tests used. Two supplementary conclusions are that the relations found tend to be task-specific, and that outward location bias cannot be adequately considered in isolation from other stimulus and subject characteristics, for example, the role of verbalization in responding to nonverbal cues. Implications are cited for the understanding of the relations between perceptual and intellectual variables, and for the design of instructional materials and settings.
