description: The minimal work principle asserts that work done on a thermally isolated equilibrium system, is minimal for the slowest (adiabatic) realization of a given process. This principle, one of the formulations of the second law, is operationally well-defined for any finite (few particle) Hamiltonian system. Within classical Hamiltonian mechanics, we show that the principle is valid for a system of which the observable of work is an ergodic function. For non-ergodic systems the principle may or may not hold, depending on additional conditions. Examples displaying the limits of the principle are presented and their direct experimental realizations are discussed.

description: Η διπλωματική μου εργασία έχει ως αντικείμενο την εξεύρεση μιας περιβαλλοντικά φιλικής και βιώσιμης λύσης που θα αντιμετωπίσει το χρόνιο πρόβλημα της διάβρωσης της ακτογραμμής της Παραλίας Κατερίνης. Ένα πρόβλημα που δημιουργήθηκε στις αρχές της δεκαετίας του 1980 με την κατασκευή του αλιευτικού καταφυγίου και δεν έχει επιλυθεί μέχρι σήμερα, παρά τις επεμβάσεις που πραγματοποιήθηκαν επί σειρά ετών. Η προτεινόμενη λύση αφορά την καθαίρεση του υπάρχοντος αλιευτικού καταφυγίου και την κατασκευή μιας προβλήτας σε μεγαλύτερο βάθος, η οποία θα συνδέεται με την ακτή με γέφυρα. Χρησιμοποιήθηκαν μαθηματικά, υδροδυναμικά και μορφοδυναμικά μοντέλα προσομοίωσης των διεργασιών που λαμβάνουν χώρα στην παράκτια ζώνη με στόχο να διερευνηθεί η αποτελεσματικότητα της προτεινόμενης λύσης. Αρχικά χρησιμοποιήθηκε το μοντέλο κυματογενούς κυκλοφορίας WICIR (Wave Induced CIRculation), το οποίο πραγματοποιεί προσομοίωση των παράκτιων κυματογενών ρευμάτων που δημιουργούνται λόγω απώλειας της ενέργειας των κυματισμών, κυρίως λόγω της θραύσης τους, σε συνδυασμό με την επίδραση των φαινομένων της διάθλασης και της περίθλασης. Στη συνέχεια χρησιμοποιήθηκε το μοντέλο στερεομεταφοράς και εξέλιξης μορφολογίας πυθμένα SEDTR (SEDiment TRansport). Η εφαρμογή των παραπάνω μοντέλων χρησιμοποιήθηκε στο πλαίσιο της προτεινόμενης λύσης με στόχο να εξαχθούν συμπεράσματα σχετικά με την αποτελεσματικότητά της ως προς την προστασίας της ακτογραμμής της Παραλίας Κατερίνης από διάβρωση
description: My master thesis aims at determining an environmentally friendly and sustainable solution that will address the chronic problem of the erosion of the shoreline in the locality of Paralia Katerini, Greece. This problem was created in the early 1980s with the construction of a fishing shelter and has not been resolved to date, despite the interventions that have taken place over the years. The proposed solution suggests the demolition of the existing fishing shelter and the construction of a wharf located far from the coastline which will be then connected by a bridge. Mathematical, hydrodynamic and morphodynamic simulation models of the processes taking place in the coastal zone were used to investigate the effectiveness of the proposed solution. Initially, WICIR (Wave Induced CIRculation) was used to simulate coastal wave currents, generated due to loss of waves energy, mainly due to their fracture, combined with the effects of refraction and diffraction. Finally, the SEDTR (SEDiment TRansport) model was used, which illustrates the long term two dimensional changes in the morphology of the seabed and the shoreline caused by natural and anthropogenical phenomena. The implementation of the above models was used to draw conclusions on its effectiveness in protecting the coastline of Paralia Katerini from erosion.

description: We study the intercommuting of semilocal strings and Skyrmions, for a wide range of internal parameters, velocities and intersection angles by numerically evolving the equations of motion. We find that the collisions of strings and strings, strings and Skyrmions, and Skyrmions and Skyrmions, all lead to intercommuting for a wide range of parameters. Even the collisions of unstable Skyrmions and strings leads to intercommuting, demonstrating that the phenomenon of intercommuting is very robust, extending to dissimilar field configurations that are not stationary solutions. Even more remarkably, at least for the semilocal U(2) formulation considered here, all intercommutations trigger a reversion to U(1) Nielsen-Olesen strings.

Two dots in series are created by lithographically defined top-gates with a procedure involving no extra insulating layer. We demonstrate the full tunability from strong to weak coupling between the dots. The quantum mechanical nature of the coupling leads to the formation of a molecular state extending over both dots. The excitation spectra of the individual dots are observable by their signatures in the nonlinear transport.

X-rays from cusps of compact remnants near galactic centres
Creators: name: Nayakshin, Sergei

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

description: Compact remnants -- stellar mass black holes and neutron stars formed in the inner few parsec of galactic centres are predicted to sink into the central parsec due to dynamical friction on low mass stars, forming a high concentration cusp (Morris 1993). Same physical region may also contain very high density molecular clouds and accretion discs that are needed to fuel SMBH activity. Here we estimate gas capture rates onto the cusp of stellar remnants, and the resulting X-ray luminosity, as a function of the accretion disc mass. At low disc masses, most compact objects are too dim to be observable, whereas in the high disc case most of them are accreting at their Eddington rates. We find that for low accretion disc masses, compact remnant cusps may be more luminous than the central SMBHs. This ``diffuse'' emission may be of importance for local moderately bright AGN, especially Low Luminosity AGN. We also briefly discuss how this expected emission can be used to put constraints on the black hole cusp near our Galactic Centre.

description: High signal to noise, high resolution spectra were obtained for a sample of normal, mild barium, and barium giants. Atmospheric parameters were determined from the FeI and FeII lines. Abundances for Na, Mg, Al, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Y, Zr, Ba, La, Ce, Nd, Sm, Eu, and Gd, were determined from equivalent widths and model atmospheres in a differential analysis, with the red giant Eps Vir as the standard star. The different levels of s-process overabundances of barium and mild barium stars were earlier suggested to be related to the stellar metallicity. Contrary to this suggestion, we found in this work no evidence of barium and mild barium to having different range in metallicity. However, comparing the ratio of abundances of heavy to light s-process elements, we found some evidence that they do not share the same neutron exposure parameter. The exact mechanism controlling this difference is still not clear. As a by-product of this analysis we identify two normal red giants misclassified as mild barium stars. The relevance of this finding is discussed. Concerning the suggested nucleosynthetic effects possibly related to the s-process, for elements like Cu, Mn, V and Sc, we found no evidence for an anomalous behavior in any of the s-process enriched stars analyzed here. However, further work is still needed since a clear [Cu/Fe] vs. [Ba/H] anticorrelation exists for other s-process enriched objects.

description: Recently, a new type of second-order topological insulator has been theoretically proposed by introducing an in-plane Zeeman field into the Kane-Mele model in the two-dimensional honeycomb lattice. A pair of topological corner states arise at the corners with obtuse angles of an isolated diamond-shaped flake. To probe the corner states, we study their transport properties by attaching two leads to the system. Dressed by incoming electrons, the dynamic corner state is very different from its static counterpart. Resonant tunneling through the dressed corner state can occur by tuning the in-plane Zeeman field. At the resonance, the pair of spatially well separated and highly localized corner states can form a dimer state, whose wavefunction extends almost the entire bulk of the diamond-shaped flake. By varying the Zeeman field strength, multiple resonant tunneling events are mediated by the same dimer state. This re-entrance effect can be understood by a simple model. These findings extend our understanding of dynamic aspects of the second-order topological corner states.

Reversible heat production during electric double layer buildup depends sensitively on the electrolyte and its reservoir

description: Several modern technologies for energy storage and conversion are based on the screening of electric charge on the surface of porous electrodes by ions in an adjacent electrolyte. This so-called electric double layer (EDL) exhibits an intricate interplay with the electrolyte's temperature that was the focus of several recent studies. In one of them, Janssen et al. [Phys. Rev. Lett. 119, 166002 (2017)] experimentally determined the ratio $\mathcal{Q}_\text{rev}/W_\text{el}$ of reversible eat flowing into a supercapacitor during an isothermal charging process and the electric work applied therein. To rationalize that data, here, we determine $\mathcal{Q}_\text{rev}/W_\text{el}$ within different models of the EDL using theoretical approaches like density functional theory (DFT) as well as molecular dynamics simulations. Applying mainly the restricted primitive model, we find quantitative support for a speculation of Janssen et al. that steric ion interactions are key to the ratio $\mathcal{Q}_\text{rev}/W_\text{el}$. Here, we identified the entropic contribution of certain DFT functionals, which grants direct access to the reversible heat. We further demonstrate how $\mathcal{Q}_\text{rev}/W_\text{el}$ changes when calculated in different thermodynamic ensembles and processes. We show that the experiments of Janssen et al. are explained best by a charging process at fixed bulk density, or in a "semi-canonical" system. Finally, we find that $\mathcal{Q}_\text{rev}/W_\text{el}$ significantly depends on parameters as pore and ion size, salt concentration, and valencies of the cat- and anions of the electrolyte. Our findings can guide further heat production measurements and can be applied in studies on, for instance, nervous conduction, where reversible heat is a key element.

description: The aim of this work is to understand the influence of chaotic states in control problems involving strong fields. Towards this end, we numerically construct and study the strong field control landscape of a bichromatically driven double well. A novel measure based on correlating the overlap intensities between Floquet states and an initial phase space coherent state with the parametric motion of the quasienergies is used to construct and interpret the landscape features. "Walls" of no control, robust under variations of the relative phase between the fields, are seen on the control landscape and associated with multilevel interactions involving chaotic Floquet states.

Market survey of California furniture manufacturers
Creators: name: Goudie, Derek
Publisher: name: University of British Columbia
Year: 2009

description: The solid wood sector of the forest products industry in British Columbia has begun to shift its focus away from the low cost manufacturing of commodity products and toward the extraction of higher value from the timber resource. One of the most important constraints to these efforts is the lack of information about markets for value-added wood products. This paper presents the results of an investigation of one such market, the wood furniture industry in California. A survey was mailed to all furniture establishments in the state. The results were compiled from the data provided by 81 respondents and were determined to be representative of the entire furniture industry in California in 1992. More than 88% of furniture manufacturers in California are single plant companies, and just under 50% employ 20 or fewer people. More than 40% of manufacturers have been operating for less than 11 years. Just under 50% of furniture manufacturers spent less than $50,000 on solid wood raw materials. This emphasizes the role played by the small manufacturer. Lumber represents about two-thirds of furniture manufacturer’s expenditures on solid wood; the remaining third is divided between semi finished components, fully-machined components and sub-assemblies. Hardwood species represent 77% of wood volume used; alder is the most popular species accounting for more than 40% of consumption followed by oak at 28% Among softwood species, ponderosa pine is the most popular accounting for just under 50% of consumption Furniture manufacturers in California rely heavily on wholesalers as a source of supply of solid wood. Most manufacturers prefer to deal with between two and four suppliers. Nearly all manufacturers use trucking as the means of inbound transport. The furniture industry in California offers potential as a market into which B.C. solid wood manufacturers can sell higher valued, specialty type wood products. The industry is fragmented and would demand a greater understanding of end-user needs than that which is used to market dimension lumber products in commodity markets. Distribution middlemen, primarily wholesalers, play an important role in supplying raw materials to furniture manufacturers in California. Any attempt to exploit opportunities in this market must begin with research into the current supply strategies and tactics of these middlemen.

Alfvenons are exact solutions of two-fluid equations for a collisionless plasma and represent natural accelerators for conversion of the electromagnetic energy flux driven by convective flows into kinetic energy of charged particles in space and astrophysical plasmas. Their properties have been experimentally verified in the magnetosphere, where they accelerate auroral electrons to tens of keV.

description: Στην παρούσα εργασία μελετήθηκε ο προσδιορισμός των ιόντων αμμωνίου με την τεχνική των εκλεκτικών ηλεκτροδίων (ISEs) σε συγκεκριμένες ειδικές εφαρμογές. Στο νερό εντοπίζεται τόσο η τοξική αδιάστατη αμμωνία όσο και το σχετικά μη τοξικό ιόν του αμμωνίου. Στην περιοχή pΗ των περισσότερων φυσικών υδάτων, το αμμωνιακό άζωτο υπάρχει κυρίως ως NH4+. Και οι δύο μορφές μετατρέπονται εύκολα μεταξύ τους, ενώ η αναλογία αμμωνίας προς αμμώνιο εξαρτάται σε μεγάλο βαθμό από το pH, την αλατότητα και τη θερμοκρασία. Το αμμώνιο κυριαρχεί όταν το pH είναι κάτω από 8,75 (κάτω από 6,5 υπάρχει κατ’ αποκλειστικότητα), ενώ η αμμωνία κυριαρχεί όταν το pΗ είναι πάνω από 9,75. Στη βιβλιογραφία αναφέρονται αναλυτικές μέθοδοι για τον προσδιορισμό του αμμωνίου ή της αμμωνίας σε υδατικά δείγματα (φυσικά και ανακυκλωμένα νερά, πόσιμο νερό, κ.ά.), ενώ έχουν αναπτυχθεί πολλές αναλυτικές μέθοδοι που βασίζονται σε αυτοματοποιημένες ή μη τεχνικές. Η παρούσα μελέτη επικεντρώθηκε στην απόδοση του ISE στον προσδιορισμό του αμμωνίου σε περίπτωση ανάγκης για ελάχιστη ανθρώπινη συμμετοχή, σε ύδατα μεταβλητής ιοντικής ισχύος (όπως εκβολές ποταμών) και σε άλλα υδατικά δείγματα. Μελετήθηκαν επίσης, οι επιπτώσεις από την παρουσία διαφόρων άλλων ιόντων στο σήμα του αμμωνίου.
description: In the present study, the determination of ammonium ions with the ion selective electrode technique (ISEs) was studied in specific applications. Both toxic non-dissociated ammonia and the relatively low toxicity ammonium ion are found in the water. In the pH area of most natural waters, ammonium nitrogen is mainly present as NH4+. Both forms are easily converted to each other, while the ammonia to ammonium ratio is highly dependent on pH, salinity and temperature. Ammonium dominates when the pH is below 8.75 (under 6.5 it is practically the only form), while ammonia dominates when the pH is above 9.75. Analytical methods for the determination of ammonium or ammonia in aqueous samples (natural and recycled waters, drinking water, etc.) are reported in the literature and many analytical methods based on automated or non-automated techniques have been developed. This study is focused on the performance of ISE in ammonium determination in case of need for minimal human involvement, in waters of variable ionic strength (such as river estuaries) and other aqueous samples. The effects of the presence of various other ions on the ammonium signal were also studied.

description: Analyticity and crossing properties of four point function are investigated in conformal field theories in the frameworks of Wightman axioms. A Hermitian scalar conformal field, satisfying the Wightman axioms, is considered. The crucial role of microcausality in deriving analyticity domains is discussed and domains of analyticity are presented. A pair of permuted Wightman functions are envisaged. The crossing property is derived by appealing to the technique of analytic completion for the pair of permuted Wightman functions. The operator product expansion of a pair of scalar fields is studied and analyticity property of the matrix elements of composite fields, appearing in the operator product expansion, is investigated. An integral representation is presented for the commutator of composite fields where microcausality is a key ingredient. Three fundamental theorems of axiomatic local field theories; namely, PCT theorem, the theorem proving equivalence between PCT theorem and weak local commutativity and the edge-of-the-wedge theorem are invoked to derive a conformal bootstrap equation rigorously.

description: New data sets have recently become available for neutrino and antineutrino deep inelastic scattering on nuclear targets and for inclusive dimuon production in pp pd interactions. These data sets are sensitive to different combinations of parton distribution functions in the large-x region and, therefore, provide different constraints when incorporated into global parton distribution function fits. We compare and contrast the effects of these new data on parton distribution fits, with special emphasis on the effects at large x. The effects of the use of nuclear targets in the neutrino and antineutrino data sets are also investigated.

description: We study the relations between two-dimensional Yang-Mills theory on the torus, topological string theory on a Calabi-Yau threefold whose local geometry is the sum of two line bundles over the torus, and Chern-Simons theory on torus bundles. The chiral partition function of the Yang-Mills gauge theory in the large N limit is shown to coincide with the topological string amplitude computed by topological vertex techniques. We use Yang-Mills theory as an efficient tool for the computation of Gromov-Witten invariants and derive explicitly their relation with Hurwitz numbers of the torus. We calculate the Gopakumar-Vafa invariants, whose integrality gives a non-trivial confirmation of the conjectured nonperturbative relation between two-dimensional Yang-Mills theory and topological string theory. We also demonstrate how the gauge theory leads to a simple combinatorial solution for the Donaldson-Thomas theory of the Calabi-Yau background. We match the instanton representation of Yang-Mills theory on the torus with the nonabelian localization of Chern-Simons gauge theory on torus bundles over the circle. We also comment on how these results can be applied to the computation of exact degeneracies of BPS black holes in the local Calabi-Yau background.

description: With the establishment and maturation of the experimental programs searching for new physics with sizeable couplings at the LHC, there is an increasing interest in the broader particle and astrophysics community for exploring the physics of light and feebly-interacting particles as a paradigm complementary to a New Physics sector at the TeV scale and beyond. FIPs 2020 has been the first workshop fully dedicated to the physics of feebly-interacting particles and was held virtually from 31 August to 4 September 2020. The workshop has gathered together experts from collider, beam dump, fixed target experiments, as well as from astrophysics, axions/ALPs searches, current/future neutrino experiments, and dark matter direct detection communities to discuss progress in experimental searches and underlying theory models for FIPs physics, and to enhance the cross-fertilisation across different fields. FIPs 2020 has been complemented by the topical workshop 'Physics Beyond Colliders meets theory', held at CERN from 7 June to 9 June 2020. This document presents the summary of the talks presented at the workshops and the outcome of the subsequent discussions held immediately after. It aims to provide a clear picture of this blooming field and proposes a few recommendations for the next round of experimental results.
Gauge invariant perturbations around symmetry reduced sectors of general relativity: applications to cosmology

description: We develop a gauge invariant canonical perturbation scheme for perturbations around symmetry reduced sectors in generally covariant theories, such as general relativity. The central objects of investigation are gauge invariant observables which encode the dynamics of the system. We apply this scheme to perturbations around a homogeneous and isotropic sector (cosmology) of general relativity. The background variables of this homogeneous and isotropic sector are treated fully dynamically which allows us to approximate the observables to arbitrary high order in a self--consistent and fully gauge invariant manner. Methods to compute these observables are given. The question of backreaction effects of inhomogeneities onto a homogeneous and isotropic background can be addressed in this framework. We illustrate the latter by considering homogeneous but anisotropic Bianchi--I cosmologies as perturbations around a homogeneous and isotropic sector.

description: The variance of an observable in a pre-selected quantum system, which is always real and non-negative, appears as an increase in the probe wave packet width in indirect measurements. Extending this framework to pre- and post-selected systems, we formulate a complex-valued counterpart of the variance called "weak variance." In our formulation, the real and imaginary parts of the weak variance appear as changes in the probe wave packet width in the vertical-horizontal and diagonal-antidiagonal directions, respectively, on the quadrature phase plane. Using an optical system, we experimentally demonstrate these changes in the probe wave packet width caused by the real negative and purely imaginary weak variances. Furthermore, we show that the weak variance can be expressed as the variance of the weak-valued probability distribution in pre- and post-selected systems. These operational and statistical interpretations support the rationality of formulating the weak variance as a complex counterpart of the variance in pre- and post-selected systems.

description: Ατµοσφαιρική ρύπανση ονοµάζεται η παρουσία ρύπων στην ατµόσφαιρα, δηλαδή η συγκέντρωση κάθε είδους ουσιών, θορύβου, ακτινοβολίας ή άλλων µορφών ενέργειας σε ποσότητα ή διάρκεια που µπορούν να προκαλέσουν αρνητικές επιπτώσεις στην υγεία των ζωντανών οργανισµών. Οι οξείες επιδράσεις σχετίζονται κυρίως με τα αναπνευστικά προβλήματα, όπως την αναπνευστική ανεπάρκεια, το άσθμα, τη χρόνια βρογχίτιδα. Ιδίως τα τελευταία χρόνια έχει αποδειχθεί ότι αφορούν και καρδιακά ή κυκλοφοριακά νοσήματα. Τα σχετικά συμπτώματα εμφανίζονται με ένα εύρος σοβαρότητας και συνήθως σε άτομα με ήδη βεβαρημένο ιστορικό. Για το λόγο αυτό τα άτομα που εισάγονται στα έκτακτα περιστατικά μετά από επεισόδια ατμοσφαιρικής ρύπανσης τείνουν δηλαδή να είναι αυτά με ήδη βεβαρημένη υγεία. Ειδικότερα, το πρόβλημα της ρύπανσης του αέρα και των επιπτώσεων της στην υγεία αποτελεί ένα από τα σημαντικότερα προβλήματα της σύγχρονης εποχής, καθώς επιβαρύνει την υγεία των ανθρώπων. Χαρακτηριστικά, η Παγκόσμια Οργάνωση Υγείας έχει υπολογίσει και έχει αναφέρει πως μέχρι και 30% των ασθενειών των ανθρώπων σχετίζονται με τη ρύπανση του αέρα, η οποία και μπορεί να ευθύνεται για την πρόκληση των θανατικών επεισοδίων σε διάφορες χώρες. Τέλος, η ρύπανση του εσωτερικού χώρου, σχετίζεται και με ένα πρόβλημα που προσβάλει όλες ανεξαρτήτως τις ηλικίες των ανθρώπων, γεγονός που προσαυξάνει την επικινδυνότητα της, στη υγεία των ανθρώπων
description: Air pollution is the presence of pollutants in the atmosphere, ie the concentration of any kind of substances, noise, radiation or other forms of energy in a quantity or duration that can cause adverse effects on the health of living organisms. Acute effects are mainly associated with respiratory problems such as respiratory failure, asthma, and chronic bronchitis. Particularly in recent years, it has been shown that they also affect cardiac or circulatory diseases. Relative symptoms appear with a range of seriousness, and usually with people with a history already tense. For this reason, people who have been introduced into emergencies after air pollution incidents tend to be those with already severe health. In particular, the problem of air pollution and its effects on health is one of the most important problems of the modern age, as it affects the health of people. Typically, the World Health Organization has calculated and reported that up to 30% of people's illnesses are related to air pollution, which may be responsible for causing death incidents in different countries. Finally, indoor pollution is also associated with a problem that affects everyone, irrespective of the ages of people, which adds to its danger to human health
An examination of property relationships in the Canadian machine stress rated lumber in-grade program
Creators: name: Griffin, Annie Helen
Publisher: name: University of British Columbia
Year: 2009

description: The Canadian lumber industry undertook two large-scale test programs for the verification of lumber design properties of Canadian species combinations. The visual lumber in-grade test program was begun in 1983 (with a prior program undertaken in 1975), while a similar program for machine graded lumber (MSR lumber) was undertaken in 1988. Some of the results of the MSR lumber in-grade test program are examined in this thesis. Stiffness and strength results from the visual lumber in-grade program are used for comparison, as are values from the MSR lumber standard. The importance of differences in methods of testing properties, particularly Modulus of Elasticity (MOE), is shown. Differences in results occur due to changes in the test span to depth ratios, measurement techniques and location of defects. The importance of knots as a cause of failure in both bending and tension is examined. The high incidence of lumber failures initiating at points where no defect was visible to the human eye is also studied.

description: Η έρευνα της διπλωματικής έχει σκοπό να διερευνήσει τη σχέση ανάμεσα στο νομικό πλαίσιο, το ιστορικό-πολιτισμικό υπόβαθρο και τις αναπαραστάσεις του γυμνού σώματος στο δημόσιο χώρο μέσω διαφόρων ειδών της τέχνης (σκάλισμα, γραφή, στένσιλ, φωτογραφία). Πρόκειται για μια συγκριτική μελέτη μεταξύ της Αθήνας και της Κοπεγχάγης, καθώς είναι δύο ευρωπαϊκές πόλεις που αναπτύχθηκαν με τελείως διαφορετικές κοινωνικές και ιστορικές συνθήκες. Ο απώτερος στόχος είναι να εξακριβωθεί εάν η τέχνη που βρίσκεται στο αστικό δημόσιο χώρο, παρά τις τάσεις της παγκοσμιοποίησης στην τέχνη, αντιπροσωπεύει και εκφράζει τις ιδιαιτερότητες κάθε πόλης που συνδέεται με την ιστορία, την παράδοση, το νόμο και την κουλτούρα κάθε πόλης / χώρας.
description: The research aim of this thesis is to explore the relationship between the legal framework, the historical and cultural background and the representations of the naked body in public space through various forms of art (sculpture, graffiti, stencil, photography). The thesis is a comparative study between Athens and Copenhagen, as they are two European cities that developed with completely different social and historical conditions. The ultimate goal is to determine whether the art we find in the urban public space, despite the tendencies of globalization in art, represents and expresses the specificities of each city that is linked somehow to the history, tradition, law and culture of each city/country.

description: We compute derived quantities for various values of the model parameter of the Cornell potential model for the S-wave heavy quarkonia with radial quantum numbers n=1, 2, and 3. Our results can be used to determine leading and relative-order-v^2 nonrelativistic quantum chromodynamics matrix elements for S-wave charmonia and bottomonia such as psi(2S), eta_c(2S), and Upsilon(nS) for n=1, 2, and 3. These matrix elements will be essential ingredients for resumming relativistic corrections to processes involving those S-wave heavy quarkonium states.

description: Ground-based arrays of imaging atmospheric Cherenkov telescopes have emerged as the most sensitive gamma-ray detectors in the energy range of about 100 GeV and above. The strengths of these arrays are a very large effective collection area on the order of 100,000 square meter, combined with excellent single photon angular and energy resolutions. The sensitivity of such detectors is limited by statistical fluctuations in the number of Cosmic Ray initiated air showers that resemble gamma-ray air showers in many ways. In this paper, we study the performance of simple event reconstruction methods when applied to simulated data of the Very Energetic Radiation Imaging Telescope Array System (VERITAS) experiment. We review methods for reconstructing the arrival direction and the energy of the primary photons, and examine means to improve on their performance. For a software threshold energy of 300 GeV (100 GeV), the methods achieve point source angular and energy resolutions of sigma[63%]= 0.1 degree (0.2 degree) and sigma[68%]= 15% (22%), respectively. The main emphasis of the paper is the discussion of gamma-hadron separation methods for the VERITAS experiment. We find that the information from several methods can be combined based on a likelihood ratio approach and the resulting algorithm achieves a gamma-hadron suppression with a quality factor that is substantially higher than that achieved with the standard methods used so far.

description: We investigate the properties of the spectral function A(omega,U) of correlated electrons within the Hubbard model and dynamical mean-field theory. Curves of A(omega,U) vs. omega for different values of the interaction U are found to intersect near the band-edges of the non-interacting system. For a wide range of U the crossing points are located within a sharply confined region. The precise location of these 'isosbestic points' depends on details of the non-interacting band structure. Isosbestic points of dynamic quantities therefore provide valuable insights into microscopic energy scales of correlated systems.
