description: Η παρούσα διπλωματική εργασία, ασχολείται με την τεχνικογεωλογική και γεωλογική μελέτη και ανάλυση κατολίσθησης κλίμακας στην περιοχή της Καστανιάς Ημαθίας, επί της Παλαιάς Εθνικής Οδού Βέροιας – Κοζάνης (Χ.Θ. 15+500). Για την ανάλυσης της οποίας, πραγματοποιήθηκε συνδυασμός στοιχείων που προήλθαν τόσο από δουλεία γραφείου (χρήση γεωλογικών και γεωτεκτονικών χαρτών, μελέτη ιστορικού περιοχής, κτλ.) όσο και από έρευνα πεδίου (γεώτρηση, τοπογραφική αποτύπωση, επί τόπου και εργαστηριακές δοκιμές, κτλ.). Από τις γεωερευνητικές εργασίες πεδίου προέκυψαν οι γεωλογικές συνθήκες του υπεδάφους, το βάθος της στάθμης των υπογείων νερών και τα γεωμετρικά χαρακτηριστικά της υπό κατολίσθηση ασταθούς περιοχής. Γενικά τα συμπεράσματα που προέκυψαν, είναι ότι πρόκειται για μία σημαντική ενεργή κατολίσθηση κλίμακας, κυκλικής μορφής, σε έντονο γεωμορφολογικό ανάγλυφο και με σχετικά έντονη κλίση της διεπιφάνειας ολίσθησης. Η μείωση της διατμητικής αντοχής κατά μήκος της διεπιφάνειας της ολίσθησης συμβαίνει με την άνοδο της στάθμης και την αύξηση της πίεσης του νερού των πόρων, η υπέρβασή της δε σημαίνει την ενεργοποίηση των μετακινήσεων κυρίως κατά την υγρή περίοδο και επιβραδύνουν δε κατά την θερινή. Ως λύση του προβλήματος προτάθηκε η κατασκευή ισχυρού με οπλισμένο σκυρόδεμα τοίχου αντιστήριξης, εδρασμένου επί πασσαλοστοιχίας
description: This thesis deals with the study and analysis of a landslide in the area of Kastania village of the Regional Unit Of Imathia (Region of Central Macedonia), on the Old National Road Veria - Kozani (km 15 + 500). For the analysis which is, a combination of elements derived both from work in office (using geological and geotectonic maps, geological history of the area, etc.), and by fieldwork (drilling, surveying, in situ and laboratory tests, etc.). From the fieldwork, came out as results, the underground geological conditions, the depth of the level of the groundwater and the geometrical characteristics of the landslide in the unstable region. Generally, the conclusions are that it is an important active landslide, with circular form, in an intense geomorphological terrain and on steep slide interface. The reduction in shear strength along the interface of the slide happens when the level of the ground water rises and is increased the pore water pressure and its exceeded means the acceleration of the movements of the slide, mainly during the wet period and slows down during the summer. As a solution to the problem was proposed the construction of strong reinforced retaining concrete wall, seated on a line of piles

description: Based on the (quantum) twisted Yangians, integrable systems with special boundary conditions, called soliton non-preserving (SNP), may be constructed. In the present article we focus on the study of subalgebras of the (quantum) twisted Yangians, and we show that such a subalgebra provides an exact symmetry of the rational transfer matrix. We discuss how the spectrum of a generic transfer matrix may be obtained by focusing only on two types of special boundaries. It is also shown that the subalgebras, emerging from the asymptotics of tensor product representations of the (quantum) twisted Yangian, turn out to be dual to the (quantum) Brauer algebra. To deal with general boundaries in the trigonometric case we propose a new algebra, which also provides the appropriate framework for the Baxterisation procedure in the SNP case.

description: Among its many uses, graphene shows significant promise for optical and optoelectronic applications. In particular, devices based on the photothermoelectric effect (PTE) in graphene can offer a strong and fast photoresponse with high signal-to-noise ratio while consuming minimal power. In this work we discuss how to optimize the performance of graphene PTE photodetectors by tuning the light confinement, device geometry, and material quality. This study should prove useful for the design of devices using the PTE in graphene, with applications including optical sensing, data communications, multi-gas sensing, and others.

description: Στόχος της παρούσας έρευνας ήταν η διερεύνηση του ψυχολογικού αντικτύπου του αυτισμού στην οικογένεια. Συγκεκριμένα μελετήθηκαν το άγχος που βιώνουν οι γονείς που μεγαλώνουν ένα παιδί με διαταραχή του αυτιστικού φάσματος, η συνοχή των οικογενειών αυτών αλλά και η επίδραση της διαταραχής στην προσαρμογή των αδελφών τυπικής ανάπτυξης και στην αδελφική σχέση. Το δείγμα αποτέλεσαν οικογένειες παιδιών με τη διαταραχή και παιδιών τυπικής ανάπτυξης. Τα δεδομένα προσεγγίστηκαν ποσοτικά και η συλλογή τους έγινε με τη χρήση ερωτηματολογίων. Για την εξαγωγή των συμπερασμάτων πραγματοποιήθηκε στατιστική ανάλυση. Τα αποτελέσματα έδειξαν ότι η ύπαρξη παιδιού με αυτισμού δημιουργεί έντονο άγχος στους γονείς, ιδίως στις μητέρες. Τα αδέλφια παιδιών με ΔΑΦ παρουσίαζαν μεγαλύτερες δυσκολίες προσαρμογής ενώ οι αδελφικές σχέσεις δεν διέφεραν ως προς τις θετικές συμπεριφορές. Καταλυτικό ρόλο φαίνεται να παίζει η ύπαρξη ή μη παρέμβασης στα παιδιά με τη διαταραχή, ενώ εξίσου σημαντική είναι και η ενημέρωση που λαμβάνουν τα αδέρφια για την αναπηρία του αδελφού τους. Συνολικά τα εξαγόμενα αποτέλεσματα μπορεί να φανούν χρήσιμα στους ειδικούς ψυχικής υγείας, τους εκπαιδευτικούς, τους γονείς και όσους ασχολούνται με τη φροντίδα των παιδιών με αυτισμό
description: The aim of this study was to investigate the psychological impact of autism spectrum disorder (ASD) on the family. Specifically, the anxiety experienced by the parents growing up a child with ASD, the cohesion of these families, and the effect of the disorder on the adaptation of typically developing (TD) siblings and on the siblings’ relationship were studied. The sample consisted of families of children with ASD and TD children. The data was quantitative and collected by administering questionnaires. A statistical analysis was performed to draw conclusions. The results showed that the experience of having a child with ASD associates with parents’symptoms of anxiety, particularly mothers’ anxiety. The TD siblings were more difficult to adapt, while siblings’ relationships did not differ in positive behaviors. The intervention seems to be catalytical for the children with ASD, while the TD children information about their sibling's disability is equally important. Overall, the exported results may be useful to mental health professionals, teachers, parents and caregivers of autistic children
The Giant Flare from SGR 1806-20 and its Radio Afterglow

description: The multi-wavelength observations of the 2004 December~27 Giant Flare (GF) from SGR 1806-20 and its long-lived radio afterglow are briefly reviewed. The GF appears to have been produced by a dramatic reconfiguration of the magnetic field near the surface of the neutron star, possibly accompanied by fractures in the crust. The explosive release of over 10^46 ergs (isotropic equivalent) powered a one-sided mildly relativistic outflow. The outflow produced a new expanding radio nebula, that is still visible over a year after the GF. Also considered are the constraints on the total energy in the GF, the energy and mass in the outflow, and on the external density, as well as possible implications for short gamma-ray bursts and potential signatures in high energy neutrinos, photons, or cosmic rays. Some possible future observations of this and other GFs are briefly discussed.

description: Dynamical conductivity spectra s(w) have been measured for a diverse range of heavy-fermion (HF) Ce and Yb compounds. A characteristic excitation peak has been observed in the mid-infrared region of s(w) for all the compounds, and has been analyzed in terms of a simple model based on conduction (c)-f electron hybridized band. A universal scaling is found between the observed peak energies and the estimated c-f hybridization strengths of these HF compounds. This scaling demonstrates that the model of c-f hybridized band can generally and quantitatively describe the charge excitation spectra of a wide range of HF compounds.

Finite temperature Drude weight of an integrable Bose chain

description: We study the Drude weight $D(T)$ at finite temperatures $T$ of an integrable bosonic model where the particles interact via nearest-neighbour coupling on a chain. At low temperatures, $D(T)$ is shown to be universal in the sense that this region is equivalently described by a Gaussian model. This low-temperature limit is also relevant for the integrable one-dimensional Bose gas. We then use the thermodynamic Bethe ansatz to confirm the low-temperature result, to obtain the high temperature limit of $D(T)$ and to calculate $D(T)$ numerically.

description: The aim of the present thesis was the study and analysis of critical success factors that contribute to a successful project management. After an analysis of conceptual definitions, the differences between project management success and project success itself were defined and explained. Furthermore, a taxonomy of critical success factors was attempted based on various case studies, and as a result coherent sets were formed according to the different sectors the various projects are evolving (constructions, IS, e-government, etc.). Finally, the contingency project management framework was analyzed that presents a less formal but interesting approach to factor evaluation, focusing more on the institutional, societal and individualistic stereotypes that may influence the successful outcome of project management

description: By controlling quantum fluctuations via the Falk-Bruch inequality we give the first rigorous argument for the existence of a spin-glass phase in the quantum Sherrington-Kirkpatrick model with a transverse magnetic field if the temperature and the field are sufficiently low. The argument also applies to the generalization of the model with multi-spin interactions, sometimes dubbed as transverse $p$-spin model.

RPAE versus RPA for the Tomonaga model with quadratic energy dispersion

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: Recently the damping of the collective charge (and spin) modes of interacting fermions in one spatial dimension was studied. It results from the nonlinear correction to the energy dispersion in the vicinity of the Fermi points. To investigate the damping one has to replace the random phase approximation (RPA) bare bubble by a sum of more complicated diagrams. It is shown here that a better starting point than the bare RPA is to use the (conserving) linearized time dependent Hartree-Fock equations, i.e. to perform a random phase approximation (with) exchange (RPAE) calculation. It is shown that the RPAE equation can be solved analytically for the special form of the two-body interaction often used in the Luttinger liquid framework. While (bare) RPA and RPAE agree for the case of a strictly linear disperson there are qualitative differences for the case of the usual nonrelativistic quadratic dispersion.

description: We simulate a spatial behavioral model of the diffusion of an infection to understand the role of geographic characteristics: the number and distribution of outbreaks, population size, density, and agents' movements. We show that several invariance properties of the SIR model concerning these variables do not hold when agents interact with neighbors in a (two dimensional) geographical space. Indeed, the spatial model's local interactions generate matching frictions and local herd immunity effects, which play a fundamental role in the infection dynamics. We also show that geographical factors affect how behavioral responses affect the epidemics. We derive relevant implications for estimating the effects of the epidemics and policy interventions that use panel data from several geographical units.

description: The MiniBooNE experiment at Fermilab has amassed the largest sample to date of $π^0$s produced in neutral current (NC) neutrino-nucleus interactions at low energy. This paper reports a measurement of the momentum distribution of $π^0$s produced in mineral oil (CH$_2$) and the first observation of coherent $π^0$ production below 2 GeV. In the forward direction, the yield of events observed above the expectation for resonant production is attributed primarily to coherent production off carbon, but may also include a small contribution from diffractive production on hydrogen. Integrated over the MiniBooNE neutrino flux, the sum of the NC coherent and diffractive modes is found to be (19.5 $\pm$1.1 (stat) $\pm$2.5 (sys))% of all exclusive NC $π^0$ production at MiniBooNE. These measurements are of immediate utility because they quantify an important background to MiniBooNE's search for $ν_μ \to ν_e$ oscillations.

description: The ultraconfined light of plasmonic modes put their effective wavelength close to the mean free path of electrons inside the metal electron gas. The Drude model, which can not take the repulsive interactions of electrons into account, then clearly begins to show its limits. In an intermediate length scale where a full quantum treatment is computationally prohibitive, the semiclassical hydrodynamic model, instrinsically non-local, has proven successful. Here we generalize the expression for the absorption volume density and the reciprocity theorem in the framework of this hydrodynamic model. We validate numerically these generalized theorems and show that using classical expressions instead leads to large discrepancies.

description: We observe the weak coupling of lead sulphide nanocrystals to localized defect modes of 2-dimensional silicon nanocavities. Cavity resonances characterized with ensemble nanocrystals are verified with cold-cavity measurements using integrated waveguides. Polarization dependence of the cavity field modes is observed. The linewidths measured in coupling experiments are broadened in comparison to the cold-cavity characterization, partly due to large homogeneous linewidths of the nanocrystals. The calculated Purcell factor for a single exciton is 75, showing promise toward applications in single photon systems. These novel light sources operate near 1.55 micron wavelengths at room temperature, permitting integration with current fiber communications networks.

description: The vibrational modes of Jahn-Teller molecules are affected by a Berry phase that is associated with a conical intersection of the adiabatic potentials. We investigate theoretically how this Berry phase affects transport through a single $E \otimes e$ Jahn-Teller molecule when the tunneling electrons continually switch the molecule between a symmetric and a Jahn-Teller distorted charge state. We find that the Berry phase in conjunction with a spectral trapping mechanism leads to a current blockade even in regions outside the Coulomb blockade. The blockade is strongly asymmetric in the gate voltage and induces pronounced negative differential conductance.

description: The aim of the present thesis is to briefly capture the changes that have taken place in the way of the operation of the Municipal Residential daycare Institute “Agios Stylianos” during the course of time. We reviewed International literature on the effect of infant placement in an institutional environment to their emotional and mental function. The assessment of infant development using the third edition of Bayley Scales of Infant and Toddler Development was presented. The developmental assessment was administered to infants and toddlers during their stay at the institute. Their performance was analyzed and presented. The difficulties that arose from the administering the developmental test in the residential nursery were described, and suggestions were made in order to make sure the findings were representative of the current state of the population studied. In addition, improvements in the daily schedule of the inmates have been proposed in order to support their psychomotor development

description: We study the role of discrete rotational symmetry in quantum key distribution by generalizing the well-known Bennett-Brassard 1984 (BB84) and Scarani-Acin-Ribordy-Gisin 2004 (SARG04) protocols. We observe that discrete rotational symmetry results in the protocol's invariance to continuous rotations, thus leading to a simplified relation between bit and phase error rates and consequently a straightforward security proof.

description: The best measurement of the cosmic ray positron flux available today was performed by the HEAT balloon experiment more than 10 years ago. Given the limitations in weight and power consumption for balloon experiments, a novel approach was needed to design a detector which could increase the existing data by more than a factor of 100. Using silicon photomultipliers for the readout of a scintillating fiber tracker and of an imaging electromagnetic calorimeter, the PEBS detector features a large geometrical acceptance of 2500 cm^2 sr for positrons, a total weight of 1500 kg and a power consumption of 600 W. The experiment is intended to measure cosmic ray particle spectra for a period of up to 20 days at an altitude of 40 km circulating the North or South Pole. A full Geant 4 simulation of the detector concept has been developed and key elements have been verified in a testbeam in October 2006 at CERN.

description: The kinematical formalism for describing spinning particles developped by the author is based upon the idea that an elementary particle is a physical system with no excited states. It can be annihilated by the interaction with its antiparticle but, if not destroyed, its internal structure can never be modified. All possible states of the particle are just kinematical modifications of any one of them. The kinematical state space of the variational formalism of an elementary particle is necessarily a homogeneous space of the kinematical group of spacetime symmetries. By assuming Poincare invariance we have already described a model of a classical spinning particle which satisfies Dirac's equation when quantized. We have recently shown that the spacetime symmetry group of this Dirac particle is larger than the Poincare group. It also contains spacetime dilations and local rotations. In this work we obtain an interaction Lagrangian for two Dirac particles, which is invariant under this enlarged spacetime group. It describes a short- and long-range interaction such that when averaged, to supress the spin content of the particles, describes the instantaneous Coulomb interaction between them. As an application, we analyse the interaction between two spinning particles, and show that it is possible the existence of metastable bound states for two particles of the same charge, when the spins are parallel and provided some initial conditions are fulfilled. The possibility of formation of bound pairs is due to the zitterbewegung spin structure of the particles because when the spin is neglected, the bound states vanish.

description: When a black hole first forms, the properties of the emitted radiation as measured by observers near future null infinity are very close to the 1974 prediction of Hawking. However, deviations grow with time, and become of order unity after a time $t \sim M_i^{7/3}$, where $M_i$ is the initial mass in Planck units. After an evaporation time the corrections are large: the angular distribution of the emitted radiation is no longer dominated by low multipoles, with an exponential fall off at high multipoles. Instead, the radiation is redistributed as a power law spectrum over a broad range of angular scales, all the way down to the scale $Δθ\sim 1/M_i$, beyond which there is exponential falloff. This effect is is a quantum gravitational effect, whose origin is the spreading of the wavefunction of the black hole's center of mass location caused by the kicks of the individual outgoing quanta, discovered by Page in 1980. The modified angular distribution of the Hawking radiation has an important consequence: the number of soft hair modes that can effectively interact with outgoing Hawking quanta increases from the handful of modes at low multipoles $l$, to a large number of modes, of order $\sim M_i^2$. We argue that this change unlocks the Hawking-Perry-Strominger mechanism for purifying the Hawking radiation.

description: We report on the discovery of two spiral galaxies located behind the southern Milky Way, within the least explored region of the Great Attractor. They lie at 317, -0.5 deg galactic, where obscuration from Milky Way stars and dust exceeds 13 to 15 mag of visual extinction. The galaxies were the most prominent of a set identified using mid-infrared images of the low-latitude (|b| < 1 deg) Spitzer Legacy program GLIMPSE. Follow-up HI radio observations reveal that both galaxies have redshifts that place them squarely in the Norma Wall of galaxies, which appears to extend diagonally across the Galactic Plane from Norma in the south to Centaurus & Vela in the north. We report on the near-infrared, mid-infrared and radio properties of these newly discovered galaxies, and discuss their context in the larger view of the Great Attractor. The work presented here demonstrates that mid-infrared surveys open up a new window to study galaxies in the Zone of Avoidance.

description: The cluster 1ES0657-556 is an ideal astrophysical laboratory to study the distribution and the nature of Dark Matter because this last component is spatially separated from the intracluster gas. We show that microwave observations can provide crucial probes of Dark Matter in this system. We calculate the expected SZ effect from Dark Matter annihilation in the main mass concentrations of the cluster 1ES0657-556, and we estimate the sources of contamination, confusion and bias to asses its significance. We find that SZ observations at a frequency of 223 GHz can resolve both spatially and spectrally the SZ_DM signal and isolate it from the other SZ signals, and mainly from the thermal SZ effect which is null at frequencies 220-223 GHz for the case of 1ES0657-556. We conclude that SZ observations with sub-arcmin resolution and micro-K sensitivity of 1ES0657-556 are crucial, and maybe unique, to find direct astrophysical probes of the existence and of the nature of Dark Matter, or to set strong experimental limits.

A Likelihood Method for Measuring the Ultrahigh Energy Cosmic Ray Composition

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Air fluorescence detectors traditionally determine the dominant chemical composit ion of the ultrahigh energy cosmic ray flux by comparing the averaged slant depth of the shower maximum, $X_{max}$, as a function of energy to the slant depths expect ed for various hypothesized primaries. In this paper, we present a method to make a direct measurement of the expected mean number of protons and iron by comparing the shap es of the expected $X_{max}$ distributions to the distribution for data. The advantages of this method includes the use of information of the full distribution and its ability to calculate a flux for various cosmic ray compositi ons. The same method can be expanded to marginalize uncertainties due to choice of spectra, hadronic models and atmospheric parameters. We demonstrate the technique with independent simulated data samples from a parent sample of protons and iron. We accurately predict the number of protons and iron in the parent sample and show that the uncertainties are meaningful.

MOND-like behavior in the Dirac-Milne universe -- Flat rotation curves and mass/velocity relations in galaxies and clusters

description: We show that in the Dirac-Milne universe (a matter-antimatter symmetric universe where the two components repel each other), rotation curves are generically flat beyond the characteristic distance of about 3 virial radii, and that a Tully-Fisher relation with exponent $\approx 3$ is satisfied. Using 3D simulations with a modified version of the RAMSES code, we show that the Dirac-Milne cosmology presents a Faber-Jackson relation with a very small scatter and an exponent equal to $\approx 3$ between the mass and the velocity dispersion. We also show that the mass derived from the rotation curves assuming Newtonian gravity is systematically overestimated compared to the mass really present. We also show that the Dirac-Milne universe, featuring a polarization between its matter and antimatter components, presents a behavior similar to that of MOND (Modified Newtonian Dynamics), characterized by an additional surface gravity compared to the Newtonian case. We show that in the Dirac-Milne universe, at the present epoch, the intensity of the additional gravitational field $g_{am}$ due to the presence of clouds of antimatter is of the order of a few $10^{-11}$ m/s$^2$, similar to the characteristic acceleration of MOND. We study the evolution of this additional acceleration $g_{am}$ and show that it depends on the redshift, and is therefore not a fundamental constant. Combined with its known concordance properties on SNIa luminosity distance, age, nucleosynthesis and structure formation, the Dirac-Milne cosmology may then represent an interesting alternative to the $Λ$CDM, MOND, and other scenarios for explaining the Dark Matter and Dark Energy conundrum.

description: A complete group classification of a class of variable coefficient (1+1)-dimensional telegraph equations $f(x)u_{tt}=(H(u)u_x)_x+K(u)u_x$, is given, by using a compatibility method and additional equivalence transformations. A number of new interesting nonlinear invariant models which have non-trivial invariance algebras are obtained. Furthermore, the possible additional equivalence transformations between equations from the class under consideration are investigated. Exact solutions of special forms of these equations are also constructed via classical Lie method and generalized conditional transformations. Local conservation laws with characteristics of order 0 of the class under consideration are classified with respect to the group of equivalence transformations.

Machine-learning interatomic potentials for materials science

Year: 2021
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: Large-scale atomistic computer simulations of materials rely on interatomic potentials providing computationally efficient predictions of energy and Newtonian forces. Traditional potentials have served in this capacity for over three decades. Recently, a new class of potentials has emerged, which is based on a radically different philosophy. The new potentials are constructed using machine-learning (ML) methods and a massive reference database generated by quantum-mechanical calculations. While the traditional potentials are derived from physical insights into the nature of chemical bonding, the ML potentials utilize a high-dimensional mathematical regression to interpolate between the reference energies. We review the current status of the interatomic potential field, comparing the strengths and weaknesses of the traditional and ML potentials. A third class of potentials is introduced, in which an ML model is coupled with a physics-based potential to improve the transferability to unknown atomic environments. The discussion is focused on potentials intended for materials science applications. Possible future directions in this field are outlined.

description: We study Holstein polarons in three-dimensional anisotropic materials. Using a variational exact diagonalization technique we provide highly accurate results for the polaron mass and polaron radius. With these data we discuss the differences between polaron formation in dimension one and three, and at small and large phonon frequency. Varying the anisotropy we demonstrate how a polaron evolves from a one-dimensional to a three-dimensional quasiparticle. We thereby resolve the issue of polaron stability in quasi-one-dimensional substances and clarify to what extent such polarons can be described as one-dimensional objects. We finally show that even the local Holstein interaction leads to an enhancement of anisotropy in charge carrier motion.
