description: Σκοπός της παρούσας διπλωματικής εργασίας είναι η παρουσίαση πληροφοριών σχετικά με το τι είναι τα MOOCs, πως μπορεί να δημιουργηθεί ένα μάθημα MOOC από την αρχή, την δημιουργία του κατάλληλου χώρου όπου θα γυριστούν τα βιντεομαθήματα και φυσικά τον κατάλληλο εξοπλισμό που χρειάζεται. Απώτερος στόχος όλων αυτών ήταν να διαμορφωθούν οι κατάλληλες προϋποθέσεις, που θα επιτρέψουν στα μέλη της πανεπιστημιακής κοινότητας του ΑΠΘ να είναι σε θέση να φτιάξουν το δικό τους MOOC. Η συγκεκριμένη παράθεση πληροφοριών θα αφορά και το κατάλληλο λογισμικό για την επεξεργασία ήχου και βίντεο, όπως και την βέλτιστη πλατφόρμα για να ανέβει και να διατεθεί στο κοινό το μάθημα. Σε αυτά τα πλαίσια έγινε έρευνα που στηρίχθηκε σε βιβλία, επιστημονικά άρθρα, ιστοσελίδες για το τι είναι τα MOOCs, τι προσφέρουν στην σύγχρονη εκπαίδευση, πως ξεκίνησαν, ποια τα χαρακτηριστικά τους. Επίσης η έρευνα επεκτάθηκε και στον τρόπο παραγωγής ενός MOOC με τις διάφορες φάσεις του, τον κατάλληλο τεχνικό εξοπλισμό, το λογισμικό που είναι απαραίτητο για την επεξεργασία των βίντεο και τέλος στον τρόπο με τον οποίο μπορεί να παρουσιαστεί στους χρήστες, μέσα από μια πλατφόρμα ελεύθερου λογισμικού
description: The scope of this thesis is to present the structure of Massive Open Online Courses (MOOCs). More specifically, we discuss the evolution of MOOCs, the steps needed to create such from scratch and the proper configuration of space and equipment to videoshoot them. Furthermore, sound and video processing tools are thoroughly analyzed, as well as available online platforms to upload the material. Upon this basis, research has been supported by books, papers and websites about innovations on this field. Our final aim is to provide a compact set of information and instructions for individuals, for example academics of Aristotle University of Thessaloniki, willing to create online courses to further support their tutoring

description: We propose a new scenario for D-term inflation which appears quite straightforwardly in the open string sector of intersecting brane models. We take the inflaton to be a chiral field in a bifundamental representation of the hidden sector and we argue that a sufficiently flat potential can be brane engineered. This type of model generically predicts a near gaussian red spectrum with negligible tensor modes. We note that this model can very naturally generate a baryon asymmetry at the end of inflation via the recently proposed hidden sector baryogenesis mechanism. We also discuss the possibility that Majorana masses for the neutrinos can be simultaneously generated by the tachyon condensation which ends inflation. Our proposed scenario is viable for both high and low scale supersymmetry breaking.

Searches for Gauge-Mediated Supersymmetry Breaking Topologies in e+e- collisions at LEP2
Creators: name: Benelli, Gabriele
Publisher: name: arXiv
Year: 2006
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: In gauge-mediated supersymmetry (SUSY) breaking (GMSB) models the lightest supersymmetric particle (LSP) is the gravitino and the phenomenology is driven by the nature of the next-to-lightest SUSY particle (NLSP) which is either the lightest neutralino, the stau or mass degenerate sleptons. Since the NLSP decay length is effectively unconstrained, searches for all possible lifetime and NLSP topologies predicted by GMSB models in e+e- collisions are performed on the data sample collected by OPAL at centre-of-mass energies up to 209 GeV at LEP. Results independent of the NLSP lifetime are presented for all relevant final states including direct NLSP pair-production and, for the first time, also NLSP production via cascade decays of heavier SUSY particles. None of the searches shows evidence for SUSY particle production. Cross-section limits are presented at the 95% confidence level both for direct NLSP production and for cascade decays, providing the most general, almost model independent results. These results are then interpreted in the framework of the minimal GMSB (mGMSB) model, where large areas of the accessible parameter space are excluded. In the mGMSB model, the NLSP masses are constrained to be larger than 53.5 GeV/c^2, 87.4 GeV/c^2 and 91.9 GeV/c^2 in the neutralino, stau and slepton co-NLSP scenarios, respectively. A complete scan on the parameters of the mGMSB model is performed, constraining the universal SUSY mass scale Lambda from the direct SUSY particle searches: Lambda > 40, 27, 21, 17, 15 TeV/c^2 for messenger indices N=1, 2, 3, 4, 5 respectively, for all NLSP lifetimes.

description: We present the full ${\cal O}(α_{ew})$ electroweak radiative corrections to the Higgs-boson production in association with $Z^0$-boson pair at an electron-positron linear collider(LC) in the standard model. We analyze the dependence of the full one-loop corrections on the Higgs-boson mass $m_{H}$ and colliding energy $\sqrt{s}$. We find that the corrections significantly suppress the Born cross section, and the ${\cal O}(α_{ew})$ electroweak radiative corrections are generally between 1.0% and -15% in our chosen parameter space, which should be taken into consideration in the future precise experiments.

Satellite AVHRR observations of the intensification of the shelf break current during an upwelling event off Vancouver Island
Creators: name: Staples, Gordon C.
Publisher: name: University of British Columbia
Year: 2008

description: AVHRR satellite imagery during July 1984 was used to investigate the spatial and temporal variability of the shelf break current during an upwelling event off Vancouver Island. The onset of the order 10-day upwelling event initially appears as a plume of cold water at the tip of Brooks Peninsula. As the winds increase in strength, the plume of cold water migrates equatorward and takes on a jet-like structure that remains centred just seaward along the shelf break. As the winds dramatically weaken near the end of the upwelling event, there is intense warming of the surface waters along the shelf, but a band of cold water persists along the shelf break. Horizontal scales calculated from thermal fronts in the AVHRR imagery show that along the shelf break, the cross-shore scale is about 20 km, which is consistent with the internal Rossby radius. Approximately 70 km offshore, another thermal front is present, and this front is thought to represent the offshore extent of the shelf break current. AVHRR measurements of the SST were correlated with in situ temperature measurements, and a r² value of around 0.85 was obtained for the upper 3 m of the water column. The temporal variations in the AVHRR SST structure were related to the temporal variations of the coastal wind field, and to temporal variations in temperature measurements obtained from coastal light stations and subsurface moorings. The long-shore velocity was estimated from the AVHRR imagery, and speeds that were calculated to be from 10 and 80cm/s, were in agreement with long-shore speeds of 20 to 30 cm/s measured by a subsurface current mooring, and long-shore speeds between 10 and 100 cm/s calculated using a time-independent barotropic model. Results indicate that wind and topography play important roles in the upwelling response, and under the right conditions, AVHRR observations of SST are representative of dynamical processes within the ocean. The band of cold water along the shelf break is thought to be due to the combined processes of advection and shelf break upwelling.

description: A new channel of direct photon production from a quark gluon plasma (QGP) is explored. This process appears at Next-to-Leading-Order in the presence of a charge asymmetry in the heated matter and may be effectively described as the bremsstrahlung of a real photon from a thermal gluon. The photon production from this new mechanism is calculated in the effective theory of QCD at high temperature. The results show that the photon production rate may not as big as the annihilation and Compton scattering at low baryon density, but could become important in baryon-rich matter.

description: By taking a Poisson limit for a sequence of rare quantum objects, I derive simple formulas for the Uhlmann fidelity, the quantum Chernoff quantity, the relative entropy, and the Helstrom information. I also present analogous formulas in classical information theory for a Poisson model. An operator called the intensity operator emerges as the central quantity in the formalism to describe Poisson states. It behaves like a density operator but is unnormalized. The formulas in terms of the intensity operators not only resemble the general formulas in terms of the density operators, but also coincide with some existing definitions of divergences between unnormalized positive-semidefinite matrices. Furthermore, I show that the effects of certain channels on Poisson states can be described by simple maps for the intensity operators.

The Female españolada

Publisher: name: Università Ca’ Foscari Venezia, Italia
Year: 2015

description:

The first three generations of female directors in Spain (Helena Cortesina, Rosario Pi Brujas, Margarita Alexandre, Ana Mariscal and Josefina Molina) have used the españolada,
a cinematic genre of French import, as a privileged filmic discourse to create female models that, more or less explicitly, differ from those established by the dominant status quo. This corpus subverts the traditional parameters of such a genre, parameters that varied throughout the changes of Spain’s political background. The directors desexualized women while the official Republican discourse of the españolada sexualized them; and vice versa, when the hegemonic Francoist discourse created models of purity and chastity, women’s cinema forged erotic female figures. In spite of the differences throughout the evolution of this corpus, the protagonists persistently chose their freedom; a freedom that rarely corresponded to the stability of marriage, even though, paradoxically, the only way to obtain it was at times through their systematic decorporization, or rather, their death.

On the Available Lunar and Solar Eclipses and Babylonian Chronology

description: The recently shown two premises (Gurzadyan 2000), i.e. the absence of 56/64 year Venus cycle constraints, at the importance of the 8-year cycle in the Venus Tablet, stimulated new studies on the Chronology of the Ancient Near East (2nd millennium BC). The analysis by B.Banjevic using both premises, however, did not provide anchors of strenght similar to those of Ur III eclipses, while available solar eclipses lack unambiguous links to historical events. The Ultra-Low chronology (Gasche et al 1998), therefore, has to be considered as currently the one most reliably based on ancient astronomical records.

We derive the action at the leading order and find new vertices which are absent in the ordinary Standard Model as well as the minimal noncommutative standard model. We briefly study the phenomenological aspects of the model.

description: Exploring the structural topology of genome-based large-scale metabolic network is essential for investigating possible relations between structure and functionality. Visualization would be helpful for obtaining immediate information about structural organization. In this work, metabolic networks of 75 organisms were investigated from a topological point of view. A spread bow-tie model was proposed to give a clear visualization of the bow-tie structure for metabolic networks. The revealed topological pattern helps to design more efficient algorithm specifically for metabolic networks. This coarse-grained graph also visualizes the vulnerable connections in the network, and thus could have important implication for disease studies and drug target identifications. In addition, analysis on the reciprocal links and main cores in the GSC part of bow-tie also reveals that the bow-tie structure of metabolic networks has its own intrinsic and significant features which are significantly different from those of random networks.

description: We study the decay of the SM Higgs boson to a massive charm quark pair at the next-to-next-to-leading order QCD and next-to-leading order electroweak. At the second order of QCD coupling, we consider the exact calculation of flavour-singlet contributions where the Higgs boson couples to the internal top and bottom quark. Helpful information on the running mass effects related to Yukawa coupling may be obtained by analyzing this process. High precision production for $h\to c\bar{c}$ within the SM makes it possible to search for new physics that may induce relatively large interactions related to the charm quark. As an example, we evaluate the axion-like particle associate production with a charm quark pair in the Higgs decay and obtain some constraints for the corresponding parameters under some assumptions.

Is irradiation important for the secular evolution of low-mass X-ray binaries?
Creators: name: Ritter, H.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: It is argued that irradiation in low-mass X-ray binaries (LMXBs) caused by accretion-generated X-rays can not only change the optical appearance of LMXBs but also their outburst properties and possibly also their long-term evolution. Irradiation during an outburst of the outer parts of the accretion disc in a transient LMXB leads to drastic changes in the outburst properties. As far as the secular evolution of such systems is concerned, these changes can result in enhanced loss of mass and angular momentum from the system and, most important, in neutron star LMXBs in a much less efficient use of the transferred matter to spin up the neutron star to a ms-pulsar. Irradiation of the donor star can destabilize mass transfer and lead to irradiation-driven mass transfer cycles, i.e. to a secular evolution which differs drastically from an evolution in which irradiation is ignored. It is argued that irradiation-driven mass transfer cycles cannot occur in systems which are transient because of disc instabilities, i.e. in particular in long-period LMXBs with a giant donor. It is furthermore shown that for irradiating either the disc or the donor star, direct irradiation alone is insufficient. Rather, indirect irradiation via scattered accretion luminosity must play an important role in transient LMXBs and is, in fact, necessary to destabilize mass transfer in short-period systems by irradiating the donor star. Whether and to what extent irradiation in LMXBs does change their secular evolution depends on a number of unsolved problems which are briefly discussed at the end of this article.

description: In a joint work with D. Bennequin, we suggested that the (negative) minima of the 3-way multivariate mutual information correspond to Borromean links, paving the way for providing probabilistic analogs of linking numbers. This short note generalizes the correspondence of the minima of k-multivariate interaction information with k Brunnian links in the binary variable case. Following Jakulin and Bratko, the negativity of the associated K-L divergence of the joint probability law with its Kirkwood approximation implies an obstruction to local decomposition into lower order interactions than k, defining a local decomposition inconsistency that reverses Abramsky's contextuality local-global relation. Those negative k-links provide a straightforward definition of collective emergence in complex k-body interacting systems or dataset.

description: The spatial structure of the transition region between an insulator and an electrolyte solution was studied with x-ray scattering.The electron density profile across the n-hexane/silica sol interface (solutions with 5-nm, 7-nm, and 12-nm colloidal particles) agrees with the theory of the electrical double layer and shows separation of positive and negative charges. The interface consists of three layers, i.e., a compact layer of Na+, a loose monolayer of nanocolloidal particles as part of a thick diffuse layer, and a low-density layer sandwiched between them. Its structure is described by a model in which the potential gradient at the interface reflects the difference in the potentials of "image forces" between the cationic Na+ and anionic nanoparticles and the specific adsorption of surface charge. The density of water in the large electric field (1-10 GV/m) of the transition region and the layering of silica in the diffuse layer is discussed.

Adjoint data assimilation in an open ocean barotropic quasi-geostrophic model

Publisher: name: University of British Columbia

description: A barotropic quasi-geostrophic ocean model with open boundaries was used to model a system of mid-ocean eddies. A simplified adjoint assimilation scheme was tested to see if sparse velocity data could be assimilated into the model at regular intervals. In between the times for data assimilation, the model was integrated forward in time with an Orlanski radiating boundary condition. This assimilation scheme was tested with several model runs, illustrating the changes arising from using different eddy sizes, different density of available data, and different numerical model parameters. This scheme was also compared with a bicubic interpolation scheme. During data assimilation, the resulting velocity field was generally more accurate than that obtained by interpolation alone. However, the Orlanski radiating boundary condition was not very effective in suppressing the growth of errors after data assimilation.

description: We address the optical conductivity of undoped bilayer graphene in the presence of a finite bias voltage at finite temperature. The effects of gap parameter and stacking type on optical conductivity are discussed in the context of tight binding model Hamiltonian. Green's function approach has been implemented to find the behavior of optical conductivity of bilayer graphene within linear response theory. We have found the frequency dependence of optical conductivity for different values of gap parameter and bias voltage. Also the dependence of optical conductivity on the temperature has been investigated in details. A peak appears in the plot of optical conductivity versus frequency for different values of temperatures and bias voltage. Furthermore we find the frequency position of broad peak in optical conductivity goes to higher values with increase of gap parameter for both bernal and simple stacked bilayer graphenes.

description: We study the single-transverse spin asymmetry in semi-inclusive hadron production in deep inelastic scattering. We derive the leading contribution to the asymmetry at moderate transverse momentum $P_{h\perp}$ of the produced hadron in terms of twist-three quark-gluon correlation functions, and compare with the approach based on the factorization at fixed transverse momentum involving the asymmetric transverse-momentum and spin-dependent quark distribution. We verify that the two approaches yield identical results in this regime. By a comparison with our earlier calculations for the single-spin asymmetry in the Drell-Yan process we recover the well-established process-dependence of the time-reversal-odd transverse-momentum-dependent quark distributions that generate single-spin phenomena.

description: We report on the serendipitous discovery of the brightest Lyman Break Galaxy (LBG) currently known, a galaxy at z=2.73 that is being strongly lensed by the z=0.38 Luminous Red Galaxy (LRG) SDSS J002240.91+143110.4. The arc of this gravitational lens system, which we have dubbed the "8 o'clock arc" due to its time of discovery, was initially identified in the imaging data of the Sloan Digital Sky Survey Data Release 4 (SDSS DR4); followup observations on the Astrophysical Research Consortium (ARC) 3.5m telescope at Apache Point Observatory confirmed the lensing nature of this system and led to the identification of the arc's spectrum as that of an LBG. The arc has a spectrum and a redshift remarkably similar to those of the previous record-holder for brightest LBG (MS 1512-cB58, a.k.a "cB58"), but, with an estimated total magnitude of (g,r,i) = (20.0,19.2,19.0) and surface brightness of (mu_g,mu_r,mu_i) = (23.3, 22.5, 22.3) mag/arcsec^2, the 8 o'clock arc is thrice as bright. The 8 o'clock arc, which consists of three lensed images of the LBG, is 162deg (9.6arcsec) long and has a length-to-width ratio of 6:1. A fourth image of the LBG -- a counter-image -- can also be identified in the ARC 3.5m g-band images. A simple lens model for the system assuming a singular isothermal ellipsoid potential yields an Einstein radius of 2.91+/-0.14 arcsec, a total mass for the lensing LRG (within the (10.6+/-0.5)/h kpc enclosed by the lensed images) of 1.04x10^12/h Msun, and a magnification factor for the LBG of 12.3(+15/-3.6). The LBG itself is intrinsically quite luminous (approximately 6L*) and shows indications of massive recent star formation, perhaps as high as 160/h Msun/year.

description:

In 1845 Prosper Mérimée published the novella Carmen. In 1875 Georges Bizet proposed
an opera adaptation from the short story of the same name, immortalizing the myth of
the beautiful gypsy. The construction of the figure of Carmen has been one of the most explored
topics, as here Spain is represented as a peculiar land. This article focuses on the similarities and
differences about the representation of Carmen in two audiovisual productions: Carmen (1943)
by the Argentine director Luis César Amadori and Carmen (1983) by the Spanish Carlos Saura.
Both productions staged some topics of the Spanish culture, as, for instance, the representation
of a flamenco show, the magnetism of its protagonists, the unrequited love and the final
outcome, presented in a completely different way in the two productions. Both representations,
in their own way, consolidate the myth of Carmen, revitalizing the essence of a country considered
exotic.

description: A popular framework for false discovery control is the random effects model in which the null hypotheses are assumed to be independent. This paper generalizes the random effects model to a conditional dependence model which allows dependence between null hypotheses. The dependence can be useful to characterize the spatial structure of the null hypotheses. Asymptotic properties of false discovery proportions and numbers of rejected hypotheses are explored and a large-sample distributional theory is obtained.

Numerical study of flow physics in supersonic base-flow with mass bleed

description: Large Eddy Simulation (LES) with dynamic sub-grid scale eddy viscosity model has been applied to numerically investigate the evolution of complicated flow structures in supersonic base flow with mass bleed. Mean flow properties obtained from numerical simulations, such as axial velocity, pressure on the base surface, have been compared with the experimental measurements to show that LES is able to predict the mean flow properties with acceptable accuracy. The data obtained from LES has been further analyzed to understand the evolution of coherent structures in the flow field. Periodical shedding of vortical structures from the outer shear layer has been observed and it has also been found that this vortex shedding is associated with the flapping of the outer shear layer. The frequency of flapping of the outer shear layer has been found out and the phase-averaged streamlines have been analyzed to further study the evolution of vortical structures associated with this flapping. The phase-averaged streamline plots clearly elucidate the evolution of vortical structures along the outer shear layer. Further, the study of these structures is investigated by performing Proper Orthogonal Decomposition (POD) analysis of the data, obtained along the central plane in the wake region. The POD results also seem to agree well with the observations made in the phase averaged streamline plots, as the concentrated energy and enstropy are observed in the outer shear layer with fewer POD modes.
Proust in the Letters of Julio Cortázar (1937-1954)

description:

Analyzing the mentions of Proust in Julio Cortázar’s correspondance (between 1937
and 1954, epoch of his formation) allow to mitigate the relation of opposition which can be read
in his critical work (Teoría del túnel). This will allow us to begin a textual and temporary journey
between both authors but also in Cortázar’s own life. The mentions will allow to reconstruct the
readings that Cortázar did of Proust’s work between Bolivar (Argentina) where he was teaching
in 1937 and Venice in 1954, passing by Chivilcoy in 1940 and by Paris where he established himself
definitively in 1951. This work could provide some reflections on the plurality of Cortázar’s
writing. Also we will propose an analytical journey of convergences between two writings on the
subjective sense of the reality and his relation with art and writing.

description: We propose a model-independent quantity, $L/G$, to characterize non-Gaussian tails in beam profiles observed with the Fermilab Booster Ion Profile Monitor. This quantity can be considered a measure of beam halo in the Booster. We use beam dynamics and detector simulations to demonstrate that $L/G$ is superior to kurtosis as an experimental measurement of beam halo when realistic beam shapes, detector effects and uncertainties are taken into account. We include the rationale and method of calculation for $L/G$ in addition to results of the experimental studies in the Booster where we show that $L/G$ is a useful halo discriminator.

description: Digital educational games contribute to the educational process as they encourage students to participate actively and engage themselves with the respective activities. The use of digital educational games is not restricted to knowledge acquisition but it also concerns changes in attitudes with a view to reinforcing positive social behaviours. Through digital educational games, students can become aware of the major environmental issues and realize their role in resolving them. This particular thesis aimed at the design and creation of a digital educational game so as to promote the environmental values of rubbish collection and recycling. The research focused on the game’s usability assessment which took place through the completion of a questionnaire provided to experts. The results were positive as to the game’s good functionality and usability.

description: We present full-sky maps of the Integrated Sachs-Wolfe effect (ISW) for the MICE Grand Challenge lightcone simulation up to redshift 1.4. The maps are constructed in the linear regime using spherical Bessel transforms. We compare and contrast this procedure against analytical approximations found in the literature. By computing the ISW in the linear regime, we remove the substantial computing and storage resources required to calculate the non-linear Rees-Sciama effect. Since the linear ISW at low redshift $z\leq1$, at large angular scales, and after matter domination is $\sim 10^{2}\times$ larger in $ΔT/T$, this has a negligible impact on the maps produced and only becomes relevant on scales which are dominated by cosmic microwave background (CMB) anisotropies. The MICE simulation products have been extensively used for studies involving current and future galaxy surveys. The availability of these maps will allow MICE to be used for future galaxy and CMB cross-correlation studies, ISW reconstruction studies, and ISW void-stacking studies probed by galaxy surveys such as Dark Energy Survey, Dark Energy Spectroscopic Instrument, Euclid, and Rubin Legacy Survey of Space and Time. The pipeline developed in this study is provided as a public Python package pyGenISW. This could be used in the future studies for constructing the ISW from existing and future simulation suites probing vast sets of cosmological parameters and models.
