description: Στην παρούσα εργασία γίνεται μια προσπάθεια ανάλυσης και χαρτογράφησης του πεδίου της ηλιακής ακτινοβολίας στο έδαφος που καλύπτει όλο τον Ελλαδικό χώρο με τη χρήση Γεωγραφικών Συστημάτων Πληροφοριών (G.I.S.), λαμβάνοντας υπόψη τον παράγοντα του υψόμετρου καθώς και διαφόρων μετεωρολογικών παραγόντων. Για την ανάλυση χρησιμοποιήθηκαν μετρήσεις της ηλιακής ακτινοβολίας για 54 πόλεις της Ελλάδας, οι οποίες πάρθηκαν από το μοντέλο PVGIS για κλίση 0ο, 40ο και για κινητά πλαίσια καθώς επίσης και εμπειρικές συσχετίσεις ύψους και αποστάσεων. Για την αναγωγή των μετρήσεων των σταθμών στο χώρο χρησιμοποιήθηκε η μέθοδος της στατιστικής χωρικής επεξεργασίας Kriging. Χάρτες του πεδίου της ημερήσιας ηλιακής ακτινοβολίας κατασκευάστηκαν για διάφορες κλίμακες χρόνου (μέσοι ετήσιοι και εποχιακοί) προκειμένου να παρουσιαστούν οι διαφορές που οφείλονται στις χρονικές μεταβολές της κλίσης των ηλιακών ακτινών.
description: In this paper an attempt is made for analysis and mapping of the field of solar radiation on the ground covering the entire Hellenic country using Geographic Information Systems (GIS), taking into account the factor of altitude and various weather factors. For the analysis there were used measurements of solar radiation for 54 Greek cities, which were obtained from the model PVGIS for inclination 0ο, 40ο and for mobile frames as well as empirical correlations of height and distances. For the standardization of the measurements of the stations in the area, there was used the method of statistical spatial processing Kriging. Maps of the scope of daily solar radiation were constructed for different time scales (annual and seasonal averages) in order to illustrate the differences due to temporal changes of inclination of the solar rays.

description: We show that minimal disturbance to the robust charge ordered Pr(0.5)Ca(0.5)MnO(3) by 2.5% Al substitution on Mn-site drives the system towards ferromagnetic ground state. The history-dependent coexisting phases observed are explained as an outcome of a hindered first order transition with glass like arrest of kinetics resulting in irreversibility. Consistent with a simple phase diagram having ferromagnetic ground state, it is experimentally shown that these coexisting phases are far from the equilibrium.

Investigation of a hybrid bridge girder with reinforced concrete web and steel flanges
Creators: name: Van Leeuwen, Joost
Publisher: name: University of British Columbia
Year: 2009

description: The subject of this research program was to investigate the behaviour of a unique hybrid bridge girder under various types of loading. The hybrid girder was made up of a reinforced concrete web with steel flange plates connected to the top and bottom using steel headed shear studs. This system is known under its commercial name as "COMPO-GIRDER.™" The research program was divided in two phases. In Phase I, 20 half-scale elements were tested under shear dominated loading in a special element tester (Adebar, 1991). The objective was to investigate the interaction of horizontal and vertical shear strengths. Numerous shear failure modes were observed during the tests. The measured shear strengths were compared with the predicted shear capacities using the design provisions in the CAN/CSA-S6-88 code and the draft CHBDC code. The comparisons indicated that the code design provisions were appropriate for both the horizontal and vertical shear design of the hybrid girder elements. One full-scale bridge specimen was tested in Phase II and consisted of a hybrid girder with concrete deck panels compositely attached to it. The simply supported bridge specimen was subjected to two equal point loads at the third points. The behaviour of the test specimen was studied under service loads and increasing load until failure. Many aspects of the bridge test specimen behaviour were investigated. Perhaps the most important one was the extent of cracking in the girder under service loads. Crack widths measured at the service load level were found to meet the CEB-FJP code limits for a "Moderate" environment and the BS 5400 limits for a "Severe" environment.

description: NGC 4330 is one of the Virgo galaxies whose UV distribution shows a tail structure. An associated tail structure is also observed in the HI and H$α$ emission distributions. Previous dynamical modeling showed that the galaxy is approaching the cluster center and is therefore undergoing increasing ram pressure stripping. Recent stellar population fitting of deep optical spectra together with multiband photometry lead to the determination of the time when star formation was quenched in the galactic disk. We introduce a new version of the dynamical model that includes the diffuse ionized gas and aim to reproduce the HI, H$α$, UV distributions together with the star formation histories of the outer gas-free parts of the galactic disk. The results of 50 simulations with five different Lorentzian temporal ram-pressure profiles and five different delays between the simulation onset and peak ram pressure are presented. The inclusion of diffuse gas stripping changes significantly the HI, UV, and H$α$ emission distributions. The simulations with diffuse gas stripping naturally lead to vertical low surface density filaments in the downwind region of the galactic disk. These filaments occur less frequently in the simulations without diffuse gas stripping. The simulations with diffuse gas stripping lead to better joint fits to the SEDs and optical spectra. The HI, NUV, and H$α$ morphologies of the model snapshots which best reproduce the SEDs and optical spectra are sufficiently different to permit a selection of best-fit models. We conclude that the inclusion of diffuse gas stripping significantly improves the resemblance between the model and observations. Our preferred model yields a time to peak ram pressure of 140 Myr in the future. The spatial coincidence of the radio continuum and diffuse H$α$ tails suggests that both gas phases are stripped together.

description: No abstracts are to be cited without prior reference to the author. The mean annual temperature of the waters over the Icelandic shelf increased by about 1-2°C in 1996-2003 and have since remained high, except for the deeper parts of the northern shelf where temperatures have been stable. Here, we present changes in abundance and distribution of two groups of groundfish under this climate change, i.e. southern warm-water species and northern cold-water species, using data from the Icelandic groundfish survey in spring operating at depths of 20-500 m. The species were selected according to their temperature associations in the survey

description: A comparative study of pure, SiC, and C doped MgB2 wires has revealed that the SiC doping allowed C substitution and MgB2 formation to take place simultaneously at low temperatures. C substitution enhances Hc2, while the defects, small grain size and nanoinclusions induced by C incorporation and low temperature processing are responsible for the improvement in Jc. The irreversibility field (Hirr) for the SiC doped sample reached the benchmarking value of 10 T at 20 K, exceeding that of NbTi at 4.2 K. This dual reaction model also enables us to predict desirable dopants for enhancing the performance properties of MgB2.

Προς αυτή λοιπόν την κατεύθυνση, ξεκινά σκιαγραφώντας το γενικότερο φιλοσοφικό πλαίσιο μέσα στο οποίο εντάσσεται η θεωρία του Σωκράτη σχετικά με την ψυχή.

Στη συνέχεια εισάγονται οι έννοιες του μονισμού και του δυϊσμού και επιχειρείται να ελεγχθεί κατά πόσο η σχέση σώματος και ψυχής εντάσσεται σε μία από αυτές. Ιδιαίτερη έμφαση δίνεται στη λειτουργία του μύθου μέσα στον πλατωνικό διάλογο.
description: The present work aims to develop the relation between soul and body as described in Plato's dialogue Phaedo, to integrate it into the general philosophical system of the time and check whether this relation is ultimately quite oppositional or not. So, in this direction begins sketching the broader philosophical context within which fits the theory of Socrates on the soul. Followingly, it goes on to quote the Socratic arguments in Phaedo and carry out the analysis and criticism. It emphasizes on the theory of recollection and the theory of ideas, as the ground of the distinction between soul and body, of mortal and immortal. Follows the reference to other philosophical positions that influenced Plato in shaping his own theory about soul, and the development of his thought in the particular subject through the other platonic dialogs. Then are examined the attitude of Socrates and his role in the particular dialog since this constitutes his “swan song”, that calls him to realize his theories through his attitude toward his own death. Afterwards are imported the concepts of monism and dualism, and it is attempted to determine whether the relation between body and soul is subject to one of these. Particular emphasis is given in the functioning of myth in the Platonic dialogue.

description: A stochastic procedure is developed which allows one to express Pontryagin's maximum principle for dissipative quantum system solely in terms of stochastic wave functions. Time-optimal controls can be efficiently computed without computing the density matrix. Specifically, the proper dynamical update rules are presented for the stochastic costate variables introduced by Pontryagin's maximum principle and restrictions on the form of the terminal cost function are discussed. The proposed procedure is confirmed by comparing the results to those obtained from optimal control on Lindbladian dynamics. Numerically, the proposed formalism becomes time and memory efficient for large systems, and it can be generalized to describe non-Markovian dynamics.

description: A recent study by Wylie et al 2006 has revealed that s-process element abundances are enhanced relative to iron in both red giant branch and asymptotic giant branch stars of 47 Tucanae. A more detailed investigation into s-process element abundances throughout the colour-magnitude diagram of 47 Tucanae is vital in order to determine whether the observed enhancements are intrinsic to the cluster. This paper explores this possibility through observational and theoretical means. The visibility of s- and r-process element lines in synthetic spectra of giant and dwarf stars throughout the colour magnitude diagram of 47 Tucanae has been explored. It was determined that a resolving power of 10 000 was sufficient to observe s-process element abundance variations in globular cluster giant branch stars. These synthetic results were compared with the spectra of eleven 47 Tucanae giant branch stars observed during the performance verification of the Robert Stobie Spectrograph on the Southern African Large Telescope. Three s-process elements, Zr, Ba, Nd, and one r-process element, Eu, were investigated. No abundance variations were found such that [X/Fe] = 0.0 +/- 0.5 dex. It was concluded that this resolving power, R ~ 5000, was not sufficient to obtain exact abundances but upper limits on the s-process element abundances could be determined.

description: Numerical simulations of the two-point eigenvalue correlation and cluster functions of the Gaussian unitary ensemble (GUE) are carried out directly from their definitions in terms of deltas functions. The simulations are compared with analytical results which follow from three analytical formulas for the two-point GUE cluster function: (i) Wigner's exact formula in terms of Hermite polynomials, (ii) Brezin and Zee's approximate formula which is valid for points with small enough separations and (iii) French, Mello and Pandey's approximate formula which is valid on average for points with large enough separations. It is found that the oscillations present in formulas (i) and (ii) are reproduced by the numerical simulations if the width of the function used to represent the delta function is small enough and that the non-oscillating behaviour of formula (iii) is approached as the width is increased.

description: No abstracts are to be cited without prior reference to the author. In this study, the distributional pattern of northern shrimp (Pandalus borealis) on Icelandic fishing grounds was investigated by calculating the center of gravity CG for each from 1988 to 2012. The CG was then used as a response variable to see which environmental factors are likely to be affecting the direction of movement. Factors such as sea surface and bottom temperature were of main interest but other factors, such as cod abundance on the shrimp fishing ground and the total shrimp catch were also investigated. The timeline was divided in two eras. First, the years between 1988 to 2000, when the movement of the CG is in a southeastern direction, moving towards land. Secondly are the years from 2001 to 2012 when the direction is in a northwestern direction, moving away from land. A linear model showed only shrimp catch to be affecting the movement, explaining 59.7% of the observed variation. No significant relationship was found between ocean temperature and the direction of movement in neither direction. The overall movement is likely to be caused by a combination of multiple factors and needs further investigation.
Taylor dispersion with absorbing boundaries: A Stochastic Approach

description: We describe how to solve the problem of Taylor dispersion in the presence of absorbing boundaries using an exact stochastic formulation. In addition to providing a clear stochastic picture of Taylor dispersion, our method leads to closed-form expressions for all the moments of the convective displacement of the dispersing particles in terms of the transverse diffusion eigenmodes. We also find that the cumulants grow asymptotically linearly with time, ensuring a Gaussian distribution in the long-time limit. As a demonstration of the technique, the first two longitudinal cumulants (yielding respectively the effective velocity and the Taylor diffusion constant) as well as the skewness (a measure of the deviation from normality) are calculated for fluid flow in the parallel plate geometry. We find that the effective velocity and the skewness (which is negative in this case) are enhanced while Taylor dispersion is suppressed due to absorption at the boundary.

description: We present a detailed study of the dielectric and charge transport properties of the antiferromagnetic cubic spinel HgCr2S4. Similar to the findings in ferromagnetic CdCr2S4, the dielectric constant of HgCr2S4 becomes strongly enhanced in the region below 60 - 80 K, which can be ascribed to polar relaxational dynamics triggered by the onset of ferromagnetic correlations. In addition, the observation of polarization hysteresis curves indicates the development of ferroelectric order below about 70 K. Moreover, our investigations in external magnetic fields up to 5 T reveal the simultaneous occurrence of magnetocapacitance and magnetoresistance of truly colossal magnitudes in this material.

description: Nighttime monitoring of the aerosol content of the lower atmosphere is a challenging task, because appropriate reference natural light sources are lacking. Here we show that the anthropogenic night sky brightness due to city lights can be successfully used for estimating the aerosol optical depth of arbitrarily thick atmospheric layers. This method requires measuring the zenith night sky brightness with two detectors located at the limiting layer altitudes. Combined with an estimate of the overall atmospheric optical depth (available from ground-based measurements or specific satellite products), the ratio of these radiances provides a direct estimate of the differential aerosol optical depth of the air column between these two altitudes. These measurements can be made with single-channel low-cost radiance detectors widely used by the light pollution research community.

description: Nuclear reactions of interest for astrophysics and applications often rely on statistical model calculations for nuclear reaction rates, particularly for nuclei far from $β$-stability. However, statistical model parameters are often poorly constrained, where experimental constraints are particularly sparse for exotic nuclides. For example, our understanding of the breakout from the NiCu cycle in the astrophysical rp-process is currently limited by uncertainties in the statistical properties of the proton-rich nucleus $^{60}$Zn. We have determined the nuclear level density of $^{60}$Zn using neutron evaporation spectra from $^{58}$Ni($^3$He, n) measured at the Edwards Accelerator Laboratory. We compare our results to a number of theoretical predictions, including phenomenological, microscopic, and shell model based approaches. Notably, we find the $^{60}$Zn level density is somewhat lower than expected for excitation energies populated in the $^{59}$Cu(p,$γ$)$^{60}$Zn reaction under rp-process conditions. This includes a level density plateau from roughly 5-6 MeV excitation energy, which is counter to the usual expectation of exponential growth and all theoretical predictions that we explore. A determination of the spin-distribution at the relevant excitation energies in $^{60}$Zn is needed to confirm that the Hauser-Feshbach formalism is appropriate for the $^{59}$Cu(p,$γ$)$^{60}$Zn reaction rate at X-ray burst temperatures.

description: We analyze four models of epidemic spreading using a stochastic approach in which the primary stochastic variables are the numbers of individuals in each class. The stochastic approach is described by a master equation and the transition rate for each process such as infection or recovery are set up by using the law of mass action. We perform numerical simulations as well as numerical integration of the evolution equations for the average number of each class of individuals. The onset of the epidemic spreading is obtained by a linear analysis of the disease free state, from which follows the initial exponential increase of the infected and the frequency of new cases. The order parameter and the variance in the number of individuals are also obtained characterizing the onset of epidemic spreading as a critical phase transition.

description: Η προσέγγιση χωρικά σύμμορφης επιπεδότητας (conformal flatness condition, CFC) για τη μελέτη συστημάτων αστροφυσικού ενδιαφέροντος έχει γνωρίσει σημαντική ανάπτυξη τα τελευταία χρόνια. Αυτό όμως δεν αίρει την ανάγκη για συνεχή επιβεβαίωση της ισχύος της. Σ’ αυτήν την εργασία, μελετούμε την αξιοπιστία της CFC για μεμονωμένους, διαφορικά περιστρεφόμενους, σχετικιστικούς αστέρες και παράλληλα επαληθεύουμε την πολύ καλή της ποιότητα στην περίπτωση ομογενούς περιστροφής. Βασιζόμαστε στην αριθμητική μέθοδο KEH όπως υλοποιείται στον κώδικα RNS, τον οποίο επεκτείνουμε κατάλληλα ώστε να έχει τη δυνατότητα προσομοιώσεων στην προσέγγιση CFC. Τα αποτελέσματά μας είναι αρκετά ενθαρρυντικά, καθώς ακόμη και για τα ταχύτερα περιστρεφόμενα μοντέλα που κατασκευάζουμε, η απόκλιση από την πλήρη γενική θεωρία σχετικότητας βρίσκεται στα επίπεδα του 5%.
description: Many astrophysically relevant systems have been studied, in the recent years, by means of the conformal flatness condition (CFC) yielding very satisfactory results as far as the quality of CFC is concerned. However, this does not nullify the need for constant evaluation of the CFC approximation in various different systems. In this thesis, we study the quality of CFC for the case of single, differentially rotating, relativistic stars. In addition, we verify its excellent performance for the case of uniform rotation. We use the numerical scheme KEH, as it is implemented in the computational code RNS. Necessary changes are made to the code, in order to allow for calculations in the CFC approximation. Our results are very encouraging, as even for the fastest rotating models, deviation from full general relativity is around 5%.
Possibility of superconductivity in graphite intercalated with alkaline earths investigated with density functional theory

description: Using density functional theory we investigate the occurrence of superconductivity in AC$_6$ with A=Mg,Ca,Sr,Ba. We predict that at zero pressure, Ba and Sr should be superconducting with critical temperatures (T$_c$) 0.2 K and 3.0 K, respectively. We study the pressure dependence of T$_c$ assuming the same symmetry for the crystal structures at zero and finite pressures. We find that the SrC$_6$ and BaC$_6$ critical temperatures should be substantially enhanced by pressure. On the contrary, for CaC$_6$ we find that in the 0 to 5 GPa region, T$_c$ weakly increases with pressure. The increase is much smaller than what shown in several recent experiments. Thus we suggest that in CaC$_6$ a continous phase transformation, such as an increase in staging, occurs at finite pressure. Finally we argue that, although MgC$_6$ is unstable, the synthesis of intercalated systems of the kind Mg$_x$Ca$_{1-x}$C$_y$ could lead to higher critical temperatures.

description: To achieve robust motion estimation in visually degraded environments, thermal odometry has been an attraction in the robotics community. However, most thermal odometry methods are purely based on classical feature extractors, which is difficult to establish robust correspondences in successive frames due to sudden photometric changes and large thermal noise. To solve this problem, we propose ThermalPoint, a lightweight feature detection network specifically tailored for producing keypoints on thermal images, providing notable anti-noise improvements compared with other state-of-the-art methods. After that, we combine ThermalPoint with a novel radiometric feature tracking method, which directly makes use of full radiometric data and establishes reliable correspondences between sequential frames. Finally, taking advantage of an optimization-based visual-inertial framework, a deep feature-based thermal-inertial odometry (TP-TIO) framework is proposed and evaluated thoroughly in various visually degraded environments. Experiments show that our method outperforms state-of-the-art visual and laser odometry methods in smoke-filled environments and achieves competitive accuracy in normal environments.
Seismic response of the George Massey Tunnel

Publisher: name: University of British Columbia

description: The George Massey Tunnel, in Richmond, British Columbia, is a 630-meter long submerged concrete tunnel, with 550-meter and 335-meter long approaches on the north and south ends, respectively. The tunnel crosses the Fraser River and is founded on a deep deposit of unconsolidated sediments consisting mainly of sands and silts that are susceptible to liquefaction during earthquake loading. This thesis represents a comprehensive analytical investigation to evaluate the liquefaction potential of the foundation soils and the performance of the tunnel during a major earthquake. The evaluation procedures and post-liquefaction stability and deformation results are presented. Liquefaction potential analyses based on the total stress approach were conducted. Liquefaction was predicted by comparing the earthquake-induced stresses to soil resistance. Dynamic ground response analyses were performed to assess the magnitude of the cyclic stresses; the cyclic resistance of the soil was computed using various methods, depending on the soil type. Estimated acceleration levels could potentially trigger liquefaction in substantial zones of the tunnel's foundation. The residual (peak post-liquefaction) shear strength of liquefied soils was estimated to be adequate to maintain post-earthquake stability of the tunnel at all of the locations analyzed. The main problem to be addressed, therefore, was the displacements due to triggering of liquefaction i n directions transverse to- and parallel to the tunnel alignment, as a result of the 475-year seismic event. Post-liquefaction deformations of the tunnel were computed using both empirical and numerical methods. The numerical methods incorporate post-liquefaction stressstrain relationships and account for the effects of both gravity and inertia forces. Analyses suggested that liquefaction would occur at four of the five locations. Liquefaction was not predicted at the south shore. The liquefaction resistance at the south shore location was on the borderline in terms of the triggering criteria. The south shore location stratum is very similar to that of the north shore (where significant liquefaction is predicted). The displacement analyses at the two locations were compared and contrasted, revealing what movements could be expected at either end if liquefaction were to occur or not (i.e., depending on assessment of different earthquake magnitudes). Since the computed liquefaction-induced displacements were, often, beyond tolerances, potential remedial options were analyzed at the offshore location detennined to be the most susceptible to liquefaction. Those analyses showed that the use of certain remedial schemes will decrease the displacements significantly. Because it is very difficult to access the stratum directly beneath the tunnel, densification of zones adjacent to the tunnel is the most effective and economically feasible solution to limit displacements.

description: Optomechanical crystal cavities have rich perspectives for detecting and indirectly analysing biological particles, such as proteins, bacteria and viruses. In this work we demonstrate the working principle of an optomechanical crystal cavity operating under ambient conditions as a sensor of submicrometer analytes by optically monitoring the frequency shift of thermally activated mechanical modes. The resonator has been specifically designed so that the cavity region supports a particular family of low modal-volume mechanical modes, commonly known as -pinch modes-. These involve the oscillation of only a couple of adjacent cavity cells that are relatively insensitive to perturbations in other parts of the resonator. The eigenfrequency of these modes decreases as the deformation is localized closer to the centre of the resonator. Thus, by identifying specific modes that undergo a frequency shift that amply exceeds the mechanical linewidth, it is possible to infer if there are particles deposited on the resonator, how many are there and their approximate position within the cavity region.

description: These lectures present a brief review of inflationary cosmology, provide an overview of the theory of cosmological perturbations, and then focus on the conceptual problems of the current paradigm of early universe cosmology, thus motivating an exploration of the potential of string theory to provide a new paradigm. Specifically, the string gas cosmology model is introduced, and a resulting mechanism for structure formation which does not require a period of cosmological inflation is discussed.
