description: Quantum Space-Time and Phase Space with fuzzy geometric structure are studied as possible formalism for quantization of massive particles and fields. In this approach the state of nonrelativistic particle m described by the fuzzy point of fuzzy (weakly) ordered Manifold X. Due to m partial ordering in X m coordinate x principal uncertainty is generic in this ansatz. It's shown that in 1+1 dimension such Fuzzy Mechanics (FM) is equivalent to Path Integral formalism of Quantum Mechanics (QM).

description: The violation of the Noether relation between symmetries and charges is reduced to the time dependence of the charge associated to a conserved current. For the U(1) gauge symmetry a non-perturbative control of the charge commutators is obtained by an analysis of the Coulomb charged fields. From this, in the unbroken case we obtain a correct expression for the electric charge on the Coulomb states, its superselection and the presence of massless vector bosons; in the broken case, we obtain a general non-perturbative version of the Higgs phenomenon, i.e. the absence of massless Goldstone bosons and of massless vector bosons. The conservation of the (gauge dependent) current associated to the U(1) axial symmetry in QCD is shown to be compatible with the time dependence of the corresponding charge commutators and a non-vanishing eta' mass, as a consequence of the non locality of the (conserved) current.

description: Ensuring the functional correctness and safety of autonomous vehicles is a major challenge for the automotive industry. However, exhaustive physical test drives are not feasible, as billions of driven kilometers would be required to obtain reliable results. Scenariobased testing is an approach to tackle this problem and reduce necessary test drives by replacing driven kilometers with simulations of relevant or interesting scenarios. These scenarios can be generated or extracted from recorded data with machine learning algorithms or created by experts. In this paper, we propose a novel graphical scenario modeling language. The graphical framework allows experts to create new scenarios or review ones designed by other experts or generated by machine learning algorithms. The scenario description is modeled as a graph and based on behavior trees. It supports different abstraction levels of scenario description during software and test development. Additionally, the graphbased structure provides modularity and reusable sub-scenarios, an important use case in scenario modeling. A graphical visualization of the scenario enhances comprehensibility for different users. The presented approach eases the scenario creation process and increases the usage of scenarios within development and testing processes.

AGU Leptoukh Lecture - Data-driven science - the coherence of Big data, HPC, and informatics and crossing the next chasm
Creators: name: Evans, Ben
Publisher: name: Zenodo
Year: 2018

description: The colocating of scientific datasets with HPC computational infrastructure has a long and steady timeline with deepening alignment that demonstrates success. Questions of whether to “bring data to the compute”, or “compute to the data” now has decades of maturity - considering and reconsidering the benefits, weaknesses and challenges both technically and socially. The historical disconnect in approaches between the sciences with large volume data and that of the long tail of data are also now steadily closing. The standards for interoperability and interconnectivity between scientific fields have been slowly maturing, and in many cases transdisciplinary science is now a reality. Furthermore, the emergence of hyper-scale cloud utility computing now makes the ability to colocate compute processing and data storage possible for many scientists. As we approach the AGU Centenary, we clearly see the past looking different to the future. For example, when preparing for the exascale age it was known that there were going to be changes (hardware software, workflow and interconnectedness) that would require addressing many unknowns. There are now clearly more disruptions and major challenges to come for digital science and more broad applications for highly performant and resilient computing infrastructures. The technical infrastructure for underpinning science is no longer advancing according to Moore’s law (and equivalents) and is evolving in unexpected ways. These have required us to consider our software development strategy, the plan for improvements and maintainability, and reconsidering some old assumptions of data precision and reproducibility. Furthermore, we are now seeing a glimpse of the non-von Neumann computing age, which may against test more assumptions to bypass existing bottlenecks. The funding/business case and overall value proposition for celebrated open data and its FAIRness is being retested, despite the explosion in the interest and downstream opportunities that it represents. The needs of data-driven science with powerful technologies such as AI, deep learning, data analytics have much stronger requirements around the quality of data, information management and persistent exposure of its complexity. This is evolving at the same time as ubiquitous IOT, fog computing, and blockchain pipelines have emerged. In this talk I will discuss the journey so far, and consider some of the chasms yet to cross.
A Detection Threshold in the Amplitude Spectra Calculated from TESS Time-Series Data

description: We present results of time-series data simulation. We aimed at estimating the threshold used for detecting signals in amplitude spectra, calculated from simulating TESS photometry of up to one year duration. We selected the threshold at a false alarm probability FAP=0.1% and derived S/N ratios between 4.6 and 5.7 depending on the data cadence and coverage. We also provide a formula to estimate the threshold for any FAP adopted and a given number of data points. Our result confirms that, to avoid spurious detection, space-based photometry may require substantially higher S/N than that typically being employed for ground-based data.

description: This note presents the study of the conjugacy classes of elements of some given finite order n in the Cremona group of the plane. In particular, it is shown that the number of conjugacy classes is infinite if n is even, n=3 or n=5, and that it is equal to 3 (respectively 9) if n=9 (respectively 15), and is exactly 1 for all remaining odd orders. Some precise representative elements of the classes are given.

description: By virtue of their sub-hour orbital periods, ultra-compact X-ray binaries are promising sources for the space-borne gravitational-wave interferometers LISA, Taiji, and TianQin. Some of these systems contain a neutron star primary, whose spin period can be measured directly via pulse timing, or indirectly through rotational modulations of burst phenomena. It is pointed out here that since actively accreting stars, with spin frequencies in the hundreds of Hz, may continuously emit appreciable gravitational waves due to the presence of accretion-built mountains, toroidal magnetic fields, and/or $r$-mode oscillations, such binaries are also candidate sources for ground-based interferometers. Two Galactic systems (4U 1728-34 and 4U 1820-30) are identified as being potentially detectable by both LISA and aLIGO simultaneously: a dual-line detection of this sort could provide percent-level constraints on the mass, radius, and internal magnetic field strength of the neutron star. With the Einstein Telescope, we find that at least four of the known ultra-compact binaries become dual-line visible.

On the interference of $ggH$ and $c\bar{c}H$ Higgs production mechanisms and the determination of charm Yukawa coupling at the LHC

subject: FOS: Physical sciences

description: Higgs boson production in association with a charm-quark jet proceeds through two different mechanisms - one that involves the charm Yukawa coupling and the other that involves direct Higgs coupling to gluons. The interference of the two contributions requires a helicity flip and, therefore, cannot be computed with massless charm quarks. In this paper, we consider QCD corrections to the interference contribution starting from charm-gluon collisions with massive charm quarks and taking the massless limit, $m_c \to 0$. The behavior of QCD cross sections in that limit differs from expectations based on the canonical QCD factorization. This implies that QCD corrections to the interference term necessarily involve logarithms of the ratio $M_H/m_c$ whose resummation is currently unknown. Although the explicit next-to-leading order QCD computation does confirm the presence of up to two powers of $\ln(M_H/m_c)$ in the interference contribution, their overall impact on the magnitude of QCD corrections to the interference turns out to be moderate due to a cancellation between double and single logarithmic terms.

An analysis of rhyme in poetry for children
Creators: name: Harley, Avis Valerie
Publisher: name: University of British Columbia
Year: 2008

description: This thesis attempts to provide an insight into how rhyming devices and rhyme forms have been used in poetry written specifically for children. It looks at words thathave been selected by children's poets for their acoustical effect as well as their literary meaning and explores how the placement of each rhyming word affects the poem. In order to illustrate the context from which children's poetry has evolved, an overview of what is known in general about the historical roots of rhyme in the English language is reviewed through the works of the following scholars: Saintsbury, Lanz, Reeves, Fraser, Woods, Hollander, Wimsatt, and Pendlebury. Such widely differing poets as Isaac Watts (1674-1748), William Blake (1757-1827), Edward Lear (1812-1888),Lewis Carroll (1831-1898), Christina Rossetti (1830-1898),Robert Louis Stevenson (1850-1894), Walter de la Mare (1873-1956), A.A. Milne (1882-1956), David McCord (1897- ), John Ciardi (1916-1986), Eve Merriam (1916- ), and Valerie Worth (1933- ) have contributed significantly to the development and shaping of children's poetry. This paper examines how rhyme has been used by these twelve poets. 164 poems have been analyzed, totalling 2671 lines. Although basically a descriptive, historical study, some quantitative data are included in the second chapter to illustrate the following: --frequency of rhyme patterns (couplet, triplet, quatrain, etc.) --preferred stanzaic forms --percentage of stressed or unstressed line-endings. The analysis offers statistical proof that wide experimentation with all forms of children's poetry, especially free verse, has occurred in the twentieth century. Use of near-rhyme appears to have increased in the last few decades. Poets' preferences for rhyme patterns have altered over the past three hundred years, but traditional forms such as the couplet and quatrain continue to be popular choices of contemporary poets. The main purpose of this thesis is to illustrate the flexibility of rhyme by emphasizing the variety of devices and forms in which rhyme has been successfully employed in children’s poetry.

description: The FeII/MgII line flux ratio has been used as an indicator of the Fe/Mg abundance ratio in the broad line region (BLR) of active galactic nuclei (AGNs). On the basis of archival rest-frame UV spectra obtained via the Hubble Space Telescope and the Sloan Digital Sky Survey, we investigate the FeII/MgII ratios of type 1 AGNs at z < 2. Over wide dynamic ranges of AGN properties (i.e., black hole mass, AGN luminosity, and Eddington ratio), we confirm that the FeII/MgII ratio strongly correlates with Eddington ratio but not with black hole mass, AGN luminosity, or redshift. Our results suggest that the metallicity in the BLR are physically related to the accretion activity of AGNs, but not to the global properties of galaxies (i.e., galaxy mass and luminosity). With regard to the relation between the BLR metallicity and the accretion rate of AGNs, we discuss that metal cooling may play an important role in enhancing the gas inflow into the central region of host galaxies, resulting in the high accretion rate of AGNs.

description: We use the dS/CFT correspondence and bulk gravity to predict the form of the renormalized holographic three-point correlation function of the operator which is dual to the inflaton field perturbation during single-field, slow-roll inflation. Using Maldcaena's formulation of the correspondence, this correlator can be related to the three-point function of the curvature perturbation generated during single-field inflation, and we find exact agreement with previous bulk QFT calculations. This provides a consistency check on existing derivations of the non-Gaussianity from single-field inflation and also yields insight into the nature of the dS/CFT correspondence. As a result of our calculation, we obtain the properly renormalized dS/CFT one-point function, including boundary contributions where derivative interactions are present in the bulk. In principle, our method may be employed to derive the n-point correlators of the inflationary curvature perturbation within the context of (n-1)th-order perturbation theory, rather than nth-order theory as in conventional approaches.

As variáveis analisadas podem ter relação positiva ou negativa no curto prazo (cinco anos), sendo positiva no longo prazo (mais de 15 anos. Esta situação peculiar no caso de Moçambique deve ser levada em conta pelos formuladores de política econômica. Estes deverão atuar com cautela uma vez que os resultados sugerem que a Economia Moçambicana é vulnerável aos efeitos da volatilidade de curto prazo.

Let $R$ be the integral closure of $S$ in a biradical extension of degree $p^2$ of its quotient field obtained by adjoining $p$-th roots of sufficiently general square free elements $f,g\in S^p$. We show that $R$ admits a birational maximal Cohen-Macaulay module. It is noted that $R$ is not automatically Cohen-Macaulay.

description: Two cavities in different size with the photonic crystal structure have been developed for axion searches. In the cavities, the dispersion relation in the photonic crystal is utilised, and so was named to "DRiPC cavities". The size of the smaller one is 100 mm x 100 mm x 10 mm, where 16 cylindrical metal poles with a diameter of 4 mm are introduced in a 4x4 grid at 20 mm intervals. In this study, the grid interval in x direction in the small size cavity, Lx, was changed to investigate resonance frequency, Q-value, and electric field profile at each Lx. The lowest three frequencies have been compared with the ones simulated by the finite element method to be found in excellent agreement. The lowest frequency mode could be tuned from 5.10 GHz (Lx = 25.0 mm) to 6.72 GHz (13.9 mm), centering on 5.87 GHz at Lx = 20 mm. This wide range tunability, 27.7%, was suitable for a search with a modest Q-value. By examining the electric field distributions with the bead pull method, the lowest frequency mode at Lx = 16.0 - 25.0 mm were TM010-like. This mode was also obtained in a larger size cavity (180 mm x 180 mm x 20 mm x 2) with the same photonic crystal structure. These results led us to conclude a DRiPC cavity has the noble features for future axion search experiments.

description: A classification scheme for close pairs of galaxies is proposed. The scheme is motivated by the fact that the majority of apparent close pairs are in fact wide pairs in three-dimensional space. This is demonstrated by means of numerical simulations of random samples of binary galaxies and the scrutiny of the resulting projected and spatial separation distributions. Observational strategies for classifying close pairs according to the scheme are suggested. As a result, physical (i.e., bound and spatially) close pairs are identified.

Nomadismo culturale. Alla ricerca delle fonti del “sellotape selfie”

description: L’articolo propone una riflessione sul “nomadismo culturale” inteso come interscambiabilità dei ruoli dell’artista e dello spettatore: con la diffusione delle nuove tecnologie e delle reti informatiche sembra impensabile poter contrapporre all’arte la non-arte in quanto l’opera è riuscita a dilatare i confini della propria rappresentazione per immergersi nell’esperienza della vita. Esempio di tale sconfinamento è il “sellotape selfie”, la condivisione sui social network di un autoritratto fotografico con il viso deformato da giri di nastro adesivo trasparente, un fenomeno che ha iniziato a diffondersi tramite Facebook nella primavera del 2014. Qui si presentano le opere di importanti artisti contemporanei al fine di indagare le fonti di questa pratica performativa.

description: Purpose: The purpose of this article was to examine how different types of learning experiences affect naming impairment in aphasia. Methods: In 4 people with aphasia with naming impairment, we compared the benefits of naming treatment that emphasized retrieval practice (practice retrieving target names from long-term memory) with errorless learning (repetition training, which preempts retrieval practice) according to different schedules of learning. The design was within subjects. Items were administered for multiple training trials for retrieval practice or repetition in a spaced schedule (an item’s trials were separated by multiple unrelated trials) or massed schedule (1 trial intervened between an item’s trials). In the spaced condition, we studied 3 magnitudes of spacing to evaluate the impact of effortful retrieval during training on the ultimate benefits conferred by retrieval practice naming treatment. The primary outcome was performance on a retention test of naming after 1 day, with a follow-up test after 1 week. Results: Group analyses revealed that retrieval practice outperformed errorless learning, and spaced learning outperformed massed learning at retention test and at follow-up. Increases in spacing in the retrieval practice condition yielded more robust learning of retrieved information. Conclusion: This study delineates the importance of retrieval practice and spacing for treating naming impairment in aphasia.

Censoring and Selling Film Noir

Subjects: Censorship; Film Noir; Hollywood Cinema; Motion Picture Production Code; Film

description: Film noir is known for its duplicity. Industry censors considered 1940s noir cinema provocative, salacious and ‘sordid.’ Hollywood studios walked a fine line between appearing to comply with Hays office Production Code censorship while simultaneously pushing the envelope of its moral constraints, then hyping and sensationalizing censorable sex, violence and hard-hitting themes to sell noir films to the public. In fact, studios capitalized on the racy explicit nature of noir pictures in publicity contradicting assurances of censorial compliance. For instance, censor Joseph Breen was “shocked” when MGM purchased James Cain’s The Postman Always Rings Twice. It was banned for a decade. Yet, ten years later as filmmakers adapted hardboiled fiction, Breen assured religious groups it would “not be offensive.” Yet, it was promoted as “torrid,” “too hot to handle” with Lana Turner in a bathing suit finding “Love at Laguna Beach” with hunky John Garfield who clamored, “You must be a she-devil,” suggesting far more sex, skin and “savage boldness” than is shown in the film. Film noir responded to Production Code censorship and other regulatory factors, including Office of War Information Bureau of Motion Pictures restrictions on Hollywood screen depictions of the domestic American home front (or overseas combat front), and Office of Censorship strictures such as a wartime ban on screen gangsters as ‘un-American’ for propaganda purposes in World War II-era noir films centering on criminals. These multiple censorship entities often collided. This regulatory climate catalyzed the development of film noir, a dark cycle of shadowy 1940s-50s crime films that boomed by World War II and evolved over the postwar era. I will investigate extensive primary archival research—including scripts, memos from industry censors, writers, directors, producers, and publicity records—to compare how film noir was censored and sold.

Aural cuing as a stimulus for revision of expository composition at the grade-eleven level
Creators: name: McCallum, Robin I.
Publisher: name: University of British Columbia
Year: 2008

description: The purpose of the study was to examine the effect on the expository writing of grade-eleven students of an aural revision cue. 162 students were randomly assigned to three treatment groups and were asked to produce three drafts of an expository composition. The first treatment group had access to its first draft while composing the second draft; the second group reread its first draft prior to redrafting, but did not have access to the first draft while rewriting; the third group had access to a recording of the first draft, but not to the written first draft. For the third draft, all groups had access to both their previous drafts. The results showed that those subjects who received an aural cue produced significantly better final drafts than those students who redrafted using the traditional visual stimulus—their previous draft. Furthermore, the former diagnosed significantly more text-base errors in their compositions, and when revising executed significantly more changes affecting meaning, both at the paragraph and the macrotext level. The experimental group diagnosed and executed significantly fewer cosmetic changes. Additionally, the experimental group employed significantly more parallel and extended parallel topical progressions than did the control group. Treatment group two did not perform significantly better than treatment group one which received the traditional graphic cue. However, the subjects of treatment groups two and three had a common reaction to the absence of their first draft text: they were cautious and critical in their evaluations of their second drafts. The subjects of treatment group one, in marked contrast, gave very positive evaluations after the first revision session. Despite a stated dislike of the experimental treatment, the E.S.L. subjects of treatment group three achieved double the quality increase of the E.S.L. students in treatment group one. Interviews conducted with subjects of the experimental treatment support the notion that such a stimulus may serve as a powerful heuristic for revision. Students commented on the potential usefulness of the aural cue for overcoming textual saliency, for achieving a sense of distance from their work and a sense of audience, and for diagnosing problems of logic and meaning in their work.
I «favolosi denti del drago»: censura e autocensura nelle traduzioni italiane di Paradise Lost
Creators: name: Borgogni, Daniele
Publisher: name: Università degli Studi di Cagliari
Year: 2015

description: Il presente contributo discute le molteplici prassi che, sotto forma di espurgazioni religiose, adattamenti neoclassici, mutilazioni stilistiche, hanno caratterizzato le traduzioni italiane del Paradise Lost di John Milton. La difficoltà nell’accettare  l’eterodossia stilistica e religiosa del grande poeta inglese ha tradizionalmente favorito una serie di versioni infarcite di “migliorie” che hanno  offuscato o travisato il testo miltoniano anche in tempi recenti. Il contributo discute in dettaglio l’atteggiamento idiosincratico nei confronti di Milton e del suo capolavoro, nonché i pregiudizi, le pratiche di autocensura e le strategie più o meno vincenti adottate dai traduttori. La traduzione viene dunque utilizzata  come indice culturale ampio, strumento di indagine privilegiato in quanto fisiologicamente legata a pratiche di censura, ri-creazione e ri-mediazione dell’oggetto letterario nel suo passaggio tra sistemi culturali diversi.The paper highlights the religious bowdlerisations, Neoclassic adaptations and stylistic mutilations that feature so prominently in the Italian translations of Milton’s Paradise Lost.  The failure to accept Milton’s religious and stylistic heterodoxy has traditionally encouraged a translational approach that has neutralised and distorted the meaning potential of Milton’s text. The essay details and exposes the prejudicial attitude towards Milton and his masterpiece, and the translators’ biases, self-censorships, and strategies, using translation as a wide cultural indicator inherently tied to practices of censorship, re-creation and re-mediation.

Censure et écriture translingue
Creators: name: De Balsi, Sara
Publisher: name: Università degli Studi di Cagliari

description: Les écrivains translingues (Ausoni, 2010) sont des écrivains qui ont pratiqué la littérature, exclusivement ou pas, dans une langue seconde. Chez eux la « surconscience linguistique » (Gauvin, 1996), condamnation de tout écrivain – en particulier plurilingue – à penser la langue comme un objet fondamentalement étranger et toujours à (re)conquérir, est probablement la plus aigüe. L’écriture qui en résulte est une pratique du doute et de l’inconfort. Cette conscience particulière de la langue, ainsi que la pluralité des langues et des espaces littéraires (au moins deux) dans lesquels ils agissent, complexifie le rapport entre les écrivains translingues et les instances de censure et d’auto-censure.Si d’un point de vue politique écrire en langue seconde et en pays étranger est la condition pour la libération d’une voix qui avait été censurée dans le pays d’origine, à l’intérieur de la langue « adoptive », la relation entre ce qui « peut » et « ne peut pas » être dit et la confrontation avec la langue maternelle et d’autres langues se joue en termes d’imaginaire. La langue seconde est donc tantôt la langue dans laquelle on peut dire ce qui était interdit dans (par) la langue maternelle, tantôt, à l’inverse, le lieu du triomphe du mensonge ; elle est tantôt vécue comme une libération des mots, tantôt comme une contrainte ultérieure et définitive.L’analyse d’un corpus d’écrits autobiographiques translingues contemporains (Jorge Semprun, Nancy Huston et Agota Kristof, qui ont choisi d’écrire en langue française) nous permettra de présenter de différents modèles de rapport entre la censure et l’imaginaire des langues, à savoir la représentation subjective, émotive des langues que l’on retrace dans leurs œuvres.

description: Αντικείμενο της παρούσας διατριβής ήταν η διερεύνηση των μηχανισμών παραμορφώσεως θραύσεως υπογείων ανοιγμάτων κυκλικής διατομής σε ισότροπα αδύναμα υλικά. Τα ερευνητικά αντικείμενα ήταν : α. Πειραματική έρευνα με εκτέλεση δοκιμών διαξονικής φόρτισης φυσικών ομοιωμάτων σε συνθήκες επίπεδης παραμόρφωσης β. Προσομοίωση του μηχανισμού συμπεριφοράς με εφαρμογή μη-γραμμικού πλαστικού μοντέλου διπλού μηχανισμού πλαστικών παραμορφώσεων θετικά κραυνομένου τύπου. Πρωτότυπο στοιχείο της πειραματικής διαδικασίας ήταν η ενσωμάτωση στα δοκίμια μικροσκοπικών ταινιών επιμήκυνσης. Κύρια συμπεράσματα : επιβεβαιώνεται ότι έναρξη της αστοχίας λαμβάνει χώρα σε μικρή συγκριτικά δυσμενέστερη εντατική κατάσταση σε σχέση με την ικανότητα απόκρισης του υλικού. Για τον τύπο των υλικών ψαθυρής συμπεριφοράς που χρησιμοποιήθηκαν στην παρούσα έρευνα η αστοχία ελάμβανε χώρα υπό καθεστώς μονοαξονικής θλίψης. Η κατανομή των τάσεων σύμφωνα με τη θεωρία ελαστικότητας (Kirsch) δεν ισχύει στα πλαίσια μιας απλοποιητικής ελαστο-πλαστικής ερμηνείας των φαινομένων. Από τις πειραματικές καμπύλες P-ε ήταν δυνατό να εντοπισθούν χαρακτηριστικές φάσεις απόκρισης του υλικού στα τοιχώματα της κυκλικής οπής που περιγράφηκαν ως αντιστοιχούσες σε : Ελαστική συμπεριφορά, Ψευδοελαστική συμπεριφορά, Διαρροή υλικού, Αστοχία οπής
description: The main objective of the thesis, were the investigation of displacement-fracture mechanisms of a circular opening in isotropic weak materials. The investigating objects were : a. experimental research of physical models under biaxial loading. b. simulation of the behavior mechanism using a non-linear double plastic mechanism plastic model. Major conclusions : The failure initiation occures in a short distance from the excavation perimeter on the point of the worst stress state for material strength. For brittle materials used in present research the failure happened under uniaxial compression status. Stress distribution according Kirsch solutions is no valid concerning a simplify elasto-plastic approach of phenomena. From experimental curves P-ε was able to locate characteristic phases of material behavior on the wall of the circular excavation which were described corresponding to : Elastic behavior, pseudo-elastic behavior, Yield, Failure.

description: The deconvolution algorithm for measuring distribution of space charge under dc by the pressure wave propagation (PWP) method is studied in this paper. A new Fredholm integral equation of first kind, including a space charge distribution without a partial differential operator is presented. Numerical methods based on Tikhonov regularization for solving this integral equation and the original PWP equation are studied. Numerical simulation is studied for the effect of signal-to-noise ratio (SNR), and comparison with other algorithms is discussed. The numerical solution of an electric field distribution from measurements of a LDPE specimen is obtained successfully.

description: We present a method for automatised detection and analysis of quasi-periodic lineament structures from images at pixel-precision. The method exploits properties of the images' frequency domain found by using the Fourier transform. We developed this method with the goal of detecting lineament structures in an image of the Hathor cliff of comet 67P/Churyumov-Gerasimenko, which are caused by layerings and furrows in the nucleus material. Using our method, we determined the orientation and wavelength-range of these structures. The detected layering edges have similar orientations, spatial separations of 9-20 m, and are ubiquitous throughout the image. We suggest that the layerings are a global feature of the comet nucleus that provide information about formation and evolution of comet 67P. The furrows are non-uniformly distributed throughout the image. Their orientation is broadly parallel to the direction of the local gravity vector at the Hathor cliff, with spacings similar to that of the layering structures. The furrows are interpreted as signatures of local down-slope movement of cliff material. We demonstrate that the developed method is broadly applicable to the detection and analysis of various kinds of quasi-periodic structures like geological layering, folding and faulting, and texture analysis in general. In order to facilitate the application of our method, this paper is accompanied by a demo program written in Matlab.

Explorations in the semiotics of text : a method for the semiotic analysis of the picture book
Creators: name: Trifonas, Peter
Publisher: name: University of British Columbia
Year: 2008

description: The premise for the study is based upon the observations of Lewis (1990), Kiefer (1988) and Landes (1987) who identify the bifurcate nature of the picture book form to be its most unique characteristic and express the need for a structural analysis of the textual dimensions of representative works within the genre. This study, therefore, addresses how textual form of the picture book works, both lexically and visually, as a system of signs and codes to create meaning. Dependent upon two systems of signification, lexical and visual, the picture book possesses "high semantic or semiotic capacity" (Landes, 1987, p. 30). In order to understand how the bifurcate nature of textual form in the picture book functions to convey meaning in the presence of a reading/viewing consciousness, the epistemological, theoretical and methodological principles of semiotics (after Eco, 1976; 1979; Greimas, 1983; Barthes, 1964; Saint-Martin, 1987 and others) are utilized within the context of the study to develop a method for the semiotic analysis of the picture book which is identified, defined and applied in the study to representative works within the genre. The findings of the study demonstrate in semiotic terms how the formal dimensions of text in the picture book work to guide the reader/viewer through the circumstances of its lexical and visual production, or structure, from the recognition of elements and levels below the sign (e.g., semes or coloremes) (Greimas, 1983; Saint-Martin, 1987) to elements and levels above the sign (e.g., possible worlds or fabula) (Eco, 1979). Meaning-making is shown to be dependent upon the reader/viewer's ability to actualize intensionally and extensionally motivated responses (cognitive, affective and aesthetic) according to individualized systems of conceptual apparati based upon real world experience(s).

description: Η εργασία είχε ως στόχο τη διερεύνηση του προβλήματος βέλτιστης δρομολόγησης συρμών. Εξετάστηκε η ως τώρα καταγεγραμμένη εμπειρία στην επίλυση του προβλήματος κυρίως δε η διατύπωσή του ως προβλήματος μικτού ακέραιου προγραμματισμού επιλυόμενου με τη μέθοδο διακλάδωσης και φραγμού με παράλληλη χρήση ευρετικών μεθόδων. Αφού διερευνήθηκε το γενικότερο πλαίσιο εφαρμογής των λεγόμενων γενετικών αλγορίθμων εξετάστηκε η δυνατότητα εφαρμογής ενότς τέτοιου αλγορίθμου στο εν λόγω πρόβλημα. Προτάθηκε η κατάλληλη κωδικοποίηση και τελεστές ως κριτήριο τερματισμού. Στη συνέχεια εξετάστηκε σε σύγκριση με την ακριβή μέθοδο διακλάδωσης και φραγμού η ακρίβεια, η αποτελεσματικότητα και ταχύτητα του αλγόριθμου. Διαπιστώθηκε ότι υπό προϋποθέσεις ο προτεινόμενος αλγόριθμος (ονομάστηκε "GENOS"), οδηγεί σε ακριβή η σχεδόν ακριβή αποτελέσματα, Από άποψη ταχύτητας ο αλγόριθμος έχει υποσχόμενα αποτελέσματα σε προβλήματα σχετικά μεγάλου μεγέθους. Στη συνέχεια διερευνήθηκε η δυνατότητα εφαρμογής του αλγορίθμου GENOS στην ελληνική σιδηροδρομική πρακτική. Διαπιστώθηκε ότι ο αλγόριθμος GENOS όπως κάθε αλγόριθμος βέλτιστης δρομολόγησης υπό προϋποθέσεις μπορεί να συμβάλει στη βελτίωση των συνθηκών εκμετάλλευσης.
description: This work aimed at the investigation of the optimal train dispatching problem. The experience gained so far was reviewed, especially the formulation as a Mixed Integer Programming problem solved with the branch & bound method along with heuristics. After reviewing the general application framework of the so called genetic algorithms, the possibility of applying such an algorithm to the problem was investigated. Appropriate encoding and operators were proposed. Next, compared to the exact branch & bound solution, the occuracy, effectiveness and speed of the algorithm were assessed. The findings showed that if specified prerequisities are met, the algorithm (named GENOS) leads to optimal or near optimal solutions. Regarding speed, the algorithm gives promising results for large problem instances. Next, the possibility of implementing GENOS in greek practice was examined. It was found that GENOS like any optimal dispatching algorithm could contribute to the improvement of operation, if certain conditions are met.

description: Objectif L’objectif de cette revue de littérature est de mettre en évidence l’impact de la non-suture des déchirures périnéales de type et 1 et 2 sur la qualité de la cicatrisation, mais également de mettre en avant le vécu des femmes selon le traitement. Méthode La recherche a été réalisée dans trois bases de données scientifiques : CINAHL, Midirs et PubMed. Les sept articles retenus selon les critères d’inclusion et d’exclusion ont été analysés à l’aide des grilles qualitatives de Fortin et Gagnon (2010), PRISMA (2015) et STROBE (2015). Cette analyse a permis d’apporter un regard critique aux articles retenus. Résultats La non-suture ne semble pas engendrer plus de complications que la suture. Les résultats sont à prendre avec précaution car les études contenaient des données peu significatives. Conclusion La décision du traitement de ces déchirures revient aux femmes et aux professionnels. Celles-ci peuvent faire un choix éclairé une fois informées sur les différents avantages et inconvénients de chaque méthode ainsi que sur le manque de données probantes sur la non-suture. La réalisation d’études, bien menées, est nécessaire afin d’approfondir ce sujet pour apporter des réponses plus poussées sur cette thématique.
