Interpretation of selfboring pressuremeter tests in sand
Creators: name: Cunha, Renato Pinto Da
Publisher: name: University of British Columbia
Year: 2009

description: This thesis addresses the analytical interpretation of selfboring pressuremeter testing curves in sands. Emphasis is placed on the development of a new approach to analyze the data and hence to derive reliable predictions of the basic soil parameters, namely the friction angle, the lateral stress and the shear modulus. The new methodology of interpretation relies on a “curve fitting” technique to match the experimental and idealized (model) curves, from which a set of fundamental soil parameters are derived. These parameters are linked to each other in the framework of the cavity expansion model adopted. Some of the elasto-plastic models currently available are adopted for use under the new methodology of interpretation. A new model that extends the rheological equations of Hughes et al, 1977 is also developed. Pressuremeter tests under controlled conditions are analyzed in order to verify the basic assumptions of the chosen models. Some of the best calibration chamber data from the University of Cambridge (Fahey, 1986) and from the Italian ENEL-CRIS laboratory (Bellotti et a!, 1987) are used for this purpose. Once the reliability of the chosen models is established, the new methodology of interpretation is applied to field pressuremeter data. Several high quality tests carried out by the writer in a granular site in Vancouver, Canada are analyzed. The results of both field and chamber tests confirm the reliability of the new interpretation approach proposed here. The new interpretation approach also provides the engineer with a technique to numerically quantify the disturbance of the testing curve. Using the new disturbance criterion ranges for “undisturbed”, “disturbed” and “highly disturbed” testing curves are proposed. This criterion aided in the establishment of the insertion procedure of the UBC selfboring pressuremeter, allowing optimization of the insertion technique and minimization of soil disturbance during selfboring. It is believed that the contribution given in this thesis aids pressuremeter practitioners to design more economical engineering works based on reliable soil parameters derived from the selfboring pressuremeter test. Simplicity and reliability are the essential features of the proposed methodologies of insertion, testing and interpretation described herein.

A level set global optimization method for nonlinear engineering problems
Creators: name: Yassien, Hassen Ali
Publisher: name: University of British Columbia
Year: 2009

description: The mathematical equations used in civil engineering design procedures are predomi nantly nonlinear. Most civil engineering design optimization problems would therefore require the use of nonlinear programming (NLP) techniques for their solution. Those NLP packages with the ability to handle practical sizes of problems, and have been available on mainframe computers for many years, are only now becoming available on microcomputers. On top of this, these existing NLP techniques, which are dominated by the gradient methods, do not guarantee global solutions. As a consequence suitable optimization methods for civil engineering design are not being enjoyed by practitioners. In this thesis, the level set optimization method, whose theory was initially presented in “Integral global optimization” by [Chew & Zheng, 1988] was further developed to address, in particular, practical engineering problems. It was found that Level Set Pro gramming (LSP), offers a viable alternative to existing nonlinear optimization methods. While LSP does not radically alter the computational effort involved it has some unique characteristics which appear to be significant from the engineering users point of view. LSP which is classified as a direct search method of optimization, utilizes the set theory concept of a level set. It uses estimates of moments of the objective function values at the confirmed points within a level set to control the search advance and as a measure of convergence on the global optimum. The reliability and efficiency of LSP was verified by comparing its results with pub lished results for both mathematical and engineering test problems. In addition to the published test problems, a new parametrically adjustable mathematical test problem was designed to test global optimization methods in general and to explore the strengths and weaknesses of LSP in particular. Experience with these test problems showed that LSP gave similar results to those cited in the literature as well as improved results or more complete sets of global solution. The large number of solutions developed at each iteration of LSP permits meaningful graphical displays of the progressive reduction in the level set boundaries as the global solution is approached. Other displays were also found to provide insights into the solution process and a basis for diagnosing search difficulties.
Mass modelling of dwarf spheroidal galaxies: the effect of unbound stars from tidal tails and the Milky Way

description: We study the origin and properties of the population of unbound stars in the kinematic samples of dwarf spheroidal galaxies. For this purpose we have run a high resolution N-body simulation of a two-component dwarf galaxy orbiting in a Milky Way potential. The dwarf is placed on a highly eccentric orbit, its initial stellar component is in the form of an exponential disk and it has a NFW-like dark matter halo. After 10 Gyrs of evolution the dwarf produces a spheroidal stellar component and is strongly tidally stripped so that mass follows light and the stars are on almost isotropic orbits. From this final state, we create mock kinematic data sets for 200 stars by observing the dwarf in different directions. We find that when the dwarf is observed along the tidal tails the kinematic samples are strongly contaminated by unbound stars from the tails. We also study another source of possible contamination by adding stars from the Milky Way. We demonstrate that most of the unbound stars can be removed by the method of interloper rejection proposed by den Hartog & Katgert. We model the cleaned-up kinematic samples using solutions of the Jeans equation with constant mass-to-light ratio and velocity anisotropy parameter. We show that the Jeans analysis, when applied to cleaned samples, allows us to reproduce the mass and mass-to-light ratio of the dwarf with accuracy typically better than 25 percent. The analysis was applied to the new data for the Fornax dSph galaxy. We show that after careful removal of interlopers the velocity dispersion profile of Fornax can be reproduced by a model in which mass traces light with a mass-to-light ratio of 11 solar units and isotropic orbits. We demonstrate that most of the contamination in the kinematic sample of Fornax probably originates from the Milky Way. (Abridged)

description: In the presence of non-standard neutrino interactions (NSI), a degeneracy exists in neutrino oscillation data, which involves the flipping of the octant of the mixing angle ${θ_{12}}$ and the type of the neutrino mass ordering. In this article, we revisit the status of this degeneracy in the light of recent data on coherent elastic neutrino-nucleus scattering (CE$ν$NS) from the COHERENT experiment. For general relative couplings to up and down quarks, the degeneracy is disfavoured at the $2σ$ level by the latest data but remains at a higher confidence level. We investigate the requirements of future CE$ν$NS measurements to resolve the degeneracy with high significance. We find that a measurement involving both, electron and muon neutrino flavours and a target with a neutron-to-proton ratio close to 1 is required. For example, an experiment with a silicon target at the European Spallation Source can resolve the degeneracy at more than $4σ$ for arbitrary relative couplings to up and down quarks.

Exciting a dilute atomic gas of magneto-optically trapped $^{85}$Rb atoms with a weak drive resonant on one of the transitions, we observe the forward-scattered field after a sudden shut-off of the laser. The subsequent radiative dynamics, measured for various optical depths of the atomic cloud, exhibits superradiant decay rates, as well as collectively enhanced quantum beats. Our work is also the first experimental illustration of quantum beats arising from atoms initially prepared in a single excited level as a result of the vacuum-induced coupling between excited levels.

description: Given a set $X$ of "empirical" points, whose coordinates are perturbed by errors, we analyze whether it contains redundant information, that is whether some of its elements could be represented by a single equivalent point. If this is the case, the empirical information associated to $X$ could be described by fewer points, chosen in a suitable way. We present two different methods to reduce the cardinality of $X$ which compute a new set of points equivalent to the original one, that is representing the same empirical information. Though our algorithms use some basic notions of Cluster Analysis they are specifically designed for "thinning out" redundant data. We include some experimental results which illustrate the practical effectiveness of our methods.

description: Strain is a powerful experimental tool to explore new electronic states and understand unconventional superconductivity. Here, we investigate the effect of uniaxial strain on the nematic and superconducting phase of single crystal FeSe using magnetotransport measurements. We find that the resistivity response to the strain is strongly temperature dependent and it correlates with the sign change in the Hall coefficient being driven by scattering, coupling with the lattice and multiband phenomena. Band structure calculations suggest that under strain the electron pockets develop a large in-plane anisotropy as compared with the hole pocket. Magnetotransport studies at low temperatures indicate that the mobility of the dominant carriers increases with tensile strain. Close to the critical temperature, all resistivity curves at constant strain cross in a single point, indicating a universal critical exponent linked to a strain-induced phase transition. Our results indicate that the superconducting state is enhanced under compressive strain and suppressed under tensile strain, in agreement with the trends observed in FeSe thin films and overdoped pnictides, whereas the nematic phase seems to be affected in the opposite way by the uniaxial strain. By comparing the enhanced superconductivity under strain of different systems, our results suggest that strain on its own cannot account for the enhanced high $T_c$ superconductivity of FeSe systems.

description: The velocities and equivalent widths (EWs) of a set of absorption features are measured for a sample of 28 well-observed Type Ia supernovae (SN Ia) covering a wide range of properties. The values of these quantities at maximum are obtained through interpolation/extrapolation and plotted against the decline rate, and so are various line ratios. The SNe are divided according to their velocity evolution into three classes defined in a previous work of Benetti et al.: low velocity gradient (LVG), high velocity gradient (HVG) and FAINT. It is found that all the LVG SNe have approximately uniform velocities at B maximum, while the FAINT SNe have values that decrease with increasing Delta m_15(B), and the HVG SNe have a large spread. The EWs of the Fe-dominated features are approximately constant in all SNe, while those of Intermediate mass element (IME) lines have larger values for intermediate decliners and smaller values for brighter and FAINT SNe. The HVG SNe have stronger Si II 6355-A lines, with no correlation with Delta m_15(B). It is also shown that the Si II 5972 A EW and three EW ratios, including one analogous to the R(Si II) ratio introduced by Nugent et al., are good spectroscopic indicators of luminosity. The data suggest that all LVG SNe have approximately constant kinetic energy, since burning to IME extends to similar velocities. The FAINT SNe may have somewhat lower energies. The large velocities and EWs of the IME lines of HVG SNe appear correlated with each other, but are not correlated with the presence of high-velocity features in the Ca II infrared triplet in the earliest spectra for the SNe for which such data exist.

More specifically, it exploits computational methods and geospatial technologies and data (such as Geographical Information Systems, satellite images and GPS) for its smooth functionality and rich content respectively. The application includes representative subjects that belong to the fields of Geoscience and proceeds into teaching as well as testing the learner and his skills in the related subjects by prompting him to take part in various realistic scenarios and fulfil several tasks in a virtual environment.

description: We present a combined angle-resolved photoemission spectroscopy and low-energy electron diffraction (LEED) study of the prominent transition metal dichalcogenide IrTe$_2$ upon potassium (K) deposition on its surface. Pristine IrTe$_2$ undergoes a series of charge-ordered phase transitions below room temperature that are characterized by the formation of stripes of Ir dimers of different periodicities. Supported by density functional theory calculations, we first show that the K atoms dope the topmost IrTe$_2$ layer with electrons, therefore strongly decreasing the work function and shifting only the electronic surface states towards higher binding energy. We then follow the evolution of its electronic structure as a function of temperature across the charge-ordered phase transitions and observe that their critical temperatures are unchanged for K coverages of $0.13$ and $0.21$~monolayer (ML). Using LEED, we also confirm that the periodicity of the related stripe phases is unaffected by the K doping. We surmise that the charge-ordered phase transitions of IrTe$_2$ are robust against electron surface doping, because of its metallic nature at all temperatures, and due to the importance of structural effects in stabilizing charge order in IrTe$_2$.

description: X-ray photon correlation spectroscopy was used to measure the diffusive dynamics of colloidal particles in a shear flow. The results presented here show how the intensity autocorrelation functions measure both the diffusive dynamics of the particles and their flow-induced, convective motion. However, in the limit of low flow/shear rates, it is possible to obtain the diffusive component of the dynamics, which makes the method suitable for the study of the dynamical properties of a large class of complex soft-matter and biological fluids. An important benefit of this experimental strategy over more traditional X-ray methods is the minimization of X-ray induced beam damage. While the method can be applied also for photon correlation spectroscopy in the visible domain, our analysis shows that the experimental conditions under which it is possible to measure the diffusive dynamics are easier to achieve at higher q values (with X-rays).

description: We investigate a class of two-dimensional two-band microscopic models in which the inter-band repulsive interactions play the dominant role. We first demonstrate three different schemes of constraining the ratios between the three types of inter-band interactions -- density-density, spin exchange, and pair-hopping -- that render the model free of the fermionic sign-problem for any filling and, consequently, amenable to efficient Quantum Monte Carlo simulations. We then study the behavior of these sign-problem-free models in the strong-coupling regime. In the cases where spin-rotational invariance is preserved or lowered to a planar symmetry, the strong-coupling ground state is a quantum paramagnet. However, in the case where there is only a residual Ising symmetry, the strong-coupling expansion maps onto the transverse-field $J_1$-$J_2$ Ising model, whose pseudospins are associated with local inter-band magnetic order. We show that by varying the band structure parameters within a reasonable range of values, a variety of ground states and quantum critical points can be accessed in the strong-coupling regime, some of which are not realized in the weak-coupling regime. We compare these results with the case of the single-band Hubbard model, where only intra-band repulsion is present, and whose strong-coupling behavior is captured by a simple Heisenberg model.

description: Spectrophotometric observations of H-alpha and He I 6678 emission lines of the nova-like Cataclysmic Variable V3885 Sgr are presented and analyzed. The binary orbital period was determined as P = 0.20716071(22) days. Doppler Tomography was performed with both H-alpha and He I lines. Disc radial emissivity profiles were also computed. The tomography mapping of flickering sources was performed using the H-alpha line, from which we concluded that the flickering is not uniformly distributed on the disc. The observed tomogram of the flickering was compared with simulations, suggesting that the most intense flickering source in the H-alpha is not located in the accretion disc. It is proposed that the main line flickering source may be associated with the illuminated secondary star.

description: We have measured the specific heat of crystals of (Ca1-xSrx)3Ru2O7 using ac- and relaxation-time calorimetry. Special emphasis was placed on the characterization of the Neel (TN=56 K) and structural (Tc = 48 K) phase transitions in the pure, x=0 material. While the latter is believed to be first order, detailed measurements under different experimental conditions suggest that all the latent heat (with L ~ 0.3 R) is being captured in a broadened peak in the effective heat capacity. The specific heat has a mean-field-like step at TN, but its magntitude (Delta cP ~ R) is too large to be associated with a conventional itinerant electron (e.g. spin-density-wave) antiferromagnetic transition, while its entropy is too small to be associated with full ordering of localized spins. The TN transition broadens with Sr substitution while its magnitude decreases slowly. On the other hand, the entropy change associated with the Tc transition decreases rapidly with Sr substitution and is not observable for our x=0.58 sample.

description: Η εργασία μελετά τις ελληνικές χριστιανικές ταφικές επιγραφές από τον 2ο έως τον 6ο αιώνα και τη θεολογία που αυτές εκφράζουν. Αρχικά δίνεται το ιστορικό πλαίσιο της εποχής και παρουσιάζεται σύντομα η εξέλιξη των ταφικών μνημείων και των επιγραφών τους. Στη συνέχεια εξετάζονται 63 επιγραφές οι οποίες κατατάσσονται σε 11 κατηγορίες ανάλογα με το περιεχόμενό τους. Πολλές επιγραφές διακρίνονται από τις εθνικές μόνο λόγω της παρουσίας του σημείου του σταυρού ή άλλων χριστιανικών συμβόλων, ενώ σε άλλες αναγράφεται η λέξη χριστιανός. Στις επιγραφές γίνεται αναφορά στις ελπίδες για Ανάσταση των νεκρών και γίνεται σαφές ότι οι Χριστιανοί δεν πιστεύουν ότι ο θάνατος είναι το τέλος της ζωής αλλά προσωρινή ανάπαυση και ύπνος. Συχνά οι επιγραφές περιέχουν πνευματικές απειλές για όσους διαταράξουν τη γαλήνη των νεκρών, ενώ πολύ συνηθισμένες είναι οι προσευχές προς τον Θεό να χαρίσει το έλεός Του στους κεκοιμημένους.
description: The thesis studies the Greek Christian grave inscriptions from the 2nd to the 6th century and the theology they express. The historical context of the time is given firstly and it is followed by a concise presentation of the evolution of grave monuments and their inscriptions. 63 inscriptions are being studied in the thesis and are classified into 11 categories according to their content. Many inscriptions are distinguished from pagan ones because of the presence of the sign of the cross or of other Christian symbols, while on others the word Christian is being read. The inscriptions present the hope for resurrection of the dead and it is made clear that Christians do not believe that death is the end of life but a temporary rest and sleep. The inscriptions often contain spiritual threats for those who disturb the peace of the dead, while prayers to God to grant His mercy to the deceased are very common

description: We demonstrate the feasibility of ballistic electron spectroscopy as a new tool for mesoscopic physics. A quantum dot is utilised as an energy-selective detector of non-equilibrium ballistic electrons injected into a two-dimensional electron system. In this paper we use a second quantum dot as the electron injector to evaluate the scheme. We propose an application in the study of interacting 1D and 0D systems.

Στόχος της εργασίας είναι η σημασιολογική αναπαράσταση αυτών των δεδομένων. Για την επίτευξη αυτού του σκοπού γίνεται επαναχρησιμοποίηση του σημασιολογικού μοντέλου OpenBudgets.eu, το οποίο έχει αναπτυχθεί στα πλαίσια του Ευρωπαϊκού προγράμματος OpenBudgets.eu. Επιπλέον, για την πληρέστερη περιγραφή των δεδομένων των έργων, δημιουργείται νέα οντολογία που μπορεί να επαναχρησιμοποιηθεί στην δημιουργία ενός εννοιολογικού δικτύου οικονομικών δεδομένων. Τέλος, έχοντας ολοκληρώσει το σκέλος της σημασιολογικής περιγραφής των δεδομένων και τη δημοσίευσης τους, δίνουμε ένα παράδειγμα για το πώς μπορούν να αναλυθούν τα δεδομένα αυτά και να χρησιμοποιηθούν στον εντοπισμό πιθανής διαφθοράς και απάτης, με την δημιουργία χαρακτηριστικών δεικτών για τον εντοπισμό παράτυπων σημείων και την εύρεση κόκκινων σημαιών (red flags)
description: The data of the Greek Partnership Agreement (PA), former National Strategic Reference Framework for the programming period 2007-2013, are provided as Open Data by the official website of the Greek Ministry for Development and Competitiveness, ANAPTYXI.gov.gr. The purpose of this master thesis is the semantic representation of said data. To achieve this goal the semantic data model of OpenBudgets.eu is being reused. OpenBudgets.eu data model has been developed within the OpenBudgets.eu European project. Moreover, to fully describe the project data, a new ontology is being created, so it can be reused to create a conceptual economic data network. Finally, having completed the semantic representation of our data and its publishing, we give an example of how the data can be analyzed and be used to detect probable corruption and fraud by creating feature indicators for identifying red flags.

description: Cryptocurrencies have several features that set them aside from traditional currencies. In terms of market capitalization, the top five cryptocurrencies are considered for the analysis to strengthen the research's validation. The most successful crypto asset, being Bitcoin, possesses several characteristics that pose advantages and disadvantages in the financial markets. Digital convenience ensures the safety and ease of use for Bitcoin users, while decentralization also poses a primary benefit. Extreme volatility and the impact of negative externalities on the value of Bitcoin contribute to the assessment of Bitcoin trends in the market. The recent outbreak of the coronavirus (COVID-19) has shown evidence of influencing Bitcoin prices as the virus is spread across continents, leaving the global financial environment in turmoil. The classification of Bitcoin as a hedge is dependent on various factors, including global economic uncertainty. The extent to which the coronavirus impacts cryptocurrencies' hedging capabilities, especially that of Bitcoin’s, is of particular interest during the 2020 pandemic. Analyzing the literature on the influence of crisis on Bitcoin movement will explain why COVID-19 has had such a significant impact on the global financial markets, especially that of cryptocurrencies. The performance of Bitcoin, Ethereum, XRP, Tether, and Bitcoin Cash is compared to that of seven factors including commodities and indices: gold, USD, S&P 500 index, SSE index, world and emerging markets MSCI indices, and Economic Uncertainty, to better understand the hedging capabilities throughout the time of the crisis. This is done using four different multivariate GARCH specifications that account for the nature of the interaction between the cryptocurrencies and the financial variables. Although previous research finds that Bitcoin should act as a hedge during times of economic turmoil, the performance observed during COVID-19 suggests otherwise.
Exploring a SNR/Molecular Cloud Association Within HESS J1745-303

Subjects: subject: Astrophysics (astro-ph)

description: HESS J1745-303 is an extended, unidentified VHE (very high energy) gamma-ray source discovered using HESS in the Galactic Plane Survey. Since no obvious counterpart has previously been found in longer-wavelength data, the processes that power the VHE emission are not well understood. Combining the latest VHE data with recent XMM-Newton observations and a variety of source catalogs and lower-energy survey data, we attempt to match (from an energetic and positional standpoint) the various parts of the emission of HESS J1745-303 with possible candidates. Though no single counterpart is found to fully explain the VHE emission, we postulate that at least a fraction of the VHE source may be explained by a supernova-remnant/molecular-cloud association and/or a high-spin-down-flux pulsar.

title: Thionylimide and related systems

description: While the synthesis of organic thionylimino (NSO) compounds has been known for over 140 years the synthesis of inorganic species was much less known and only really begun in the 1970s. The previous syntheses for these inorganic species were often complicated and involved highly reactive species. The goal of this work was to simplify the synthesis of transition metal complexes and main group compounds containing the thionylimide anion. An existing literature synthesis was improved and developed in to a new method using a solution of thionyl chloride in tetrahydrofuran and liquid ammonia. This led to significant yield increases over previous syntheses and in a much more efficient “one-pot” reaction. The scope of the reaction was investigated and complexes and compounds containing titanium, zirconium, hafnium, platinum, copper, zinc and antimony were synthesised. The first examples of antimony(V) and copper thionylimino compounds and complexes were prepared. The series of group IV metal complexes Cp₂Ti(NSO)₂, Cp*₂M(NSO)₂ (M = Ti, Zr and Hf) was synthesised. Cp*₂M(NSO)₂ (M = Ti and Hf) are novel complexes. These complexes along with the other thionylimino compounds and complexes formed the basis of an examination of the bonding properties of the thionylimino group in inorganic compounds. The reactivity of these species was examined and led to the isolation of a transition metal complex of the [N(SO₃)₂]³⁻ anion in the complex (2,2’- bipyridyl)₃Cu₂Cl(N(SO₃)₂). This was the first transition metal complex of this anion to be examined by single crystal X-ray crystallography. The reactivity of Cp₂Ti(NSO)₂ under various conditions was examined. It was discovered that Cp₂Ti(NSO)₂ could act as a metalloligand which contains bridging thionylimino groups. These species were shown to bridge via the nitrogen atom of the thionylimino groups. A series of metal complexes containing; copper, molybdenum, cobalt, mercury, and silver were synthesised. The electrochemistry of Cp₂Ti(NSO)₂, the neutral copper complexes and the molybdenum complex was examined in detail. The synthesis of various five-membered sulfur-nitrogen rings containing phosphorus, antimony, titanium and selenium was attempted. The synthesis of the five-membered selenium nitrogen species nBu₂SnSe₂N₂ was also attempted and gave promising preliminary results.
