description: The aim of the present thesis was the study of leachate management at sanitary landfills. More specifically, the residue sanitary landfill of Alexandroupolis has been studied. At first the master thesis describes the institutional framework of solid waste management and of sanitary landfills that has been developed in Greece and in EU; as well as the study area and the project location information are described too. As the main subject of the study is leachate, a full description and many calculations are done from the leachate production to the dimensioning of the leachate collection and removal system. Also, some alternative scenarios are suggested concerning to developing of the cells inside the depositional basin, in order to reduce the leachate production and therefore the cost of the design of the leachate collection and removal system, as well as other scenarios suggested different network design in order to find a better economical solution than the original network design. Finally, we study the environmental impacts of the residue sanitary landfill of Alexandroupolis and the disposal of the treating leachate into the nearest river.
The evolution of municipal social planning
Creators: name: Adams, Felicity
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is about municipal social planning in Canada. The purpose of this work is to suggest conditions that may initiate the evolution of a process which results in a municipality introducing social planning as part of the function of local government. In the effort to identify these conditions, the oldest municipal social planning programs in Canada (Halifax and Vancouver) are examined, as well as more recent British Columbia examples. The case of the social planning program in the City ofNanaimo, British Columbia is studied in depth to shed light on the dynamics involved in establishing a municipal social planning program. In this thesis, the definition of municipal social planning utilized is borrowed from the Planning Institute of British Columbia which defines social planning as a process by which the community and government take action to support community needs, including social, physical, and economic realms. Such action includes the identification of social impacts and issues, the development of social goals, objectives, policies and priorities, the facilitation of citizen involvement, the presentation of options, and the negotiation of alternatives. A review of the literature provides the background information necessary to tell the story of the municipal role in social welfare in Canada from the 1880’s to the present day. Academic and community-based publications are surveyed to provide insight into how the literature defines “social planning.” Reports and articles by both academics and practicing social planners are reviewed to provide a description of two models of social planning: municipal and community-based. A review of both academic writings, municipal plans and studies, and community social planning documents provides a description of the typical goals, objectives and functions of social planning. The evolution of municipal social planning is learned from a review of various municipal documents and case study research. Conclusions about how municipal social planning programs are created and evolve, particularly about conditions that may initiate municipal social planning, are made through an examination of the evolution of several municipal social planning programs in Canada. The thesis concludes with the identification of seven general conditions that have preceded the introduction of municipal social planning in Canada: (1) on-going and organized citizen pressure/action; (2) lack of or minimal public involvement in decision-making; (3) significant community social issues; (4) community frustration with the allocation of social service resources by external agencies; (5) lack of effective planning and coordinating mechanisms; (6) unsatisfactory municipal response to social issues, both current and emerging; and (7) willingness on the part of the local government to initiate action.

Diversifying Semantic Image Synthesis and Editing via Class- and Layer-wise VAEs

description: Semantic image synthesis is a process for generating photorealistic images from a single semantic mask. To enrich the diversity of multimodal image synthesis, previous methods have controlled the global appearance of an output image by learning a single latent space. However, a single latent code is often insufficient for capturing various object styles because object appearance depends on multiple factors. To handle individual factors that determine object styles, we propose a class- and layer-wise extension to the variational autoencoder (VAE) framework that allows flexible control over each object class at the local to global levels by learning multiple latent spaces. Furthermore, we demonstrate that our method generates images that are both plausible and more diverse compared to state-of-the-art methods via extensive experiments with real and synthetic datasets inthree different domains. We also show that our method enables a wide range of applications in image synthesis and editing tasks.

Neutrinos and electrons in background matter: a new approach
Creators: name: Studenikin, Alexander
Publisher: name: arXiv
Year: 2006
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We present a rather powerful method in investigations of different phenomena that can appear when neutrinos and electrons are moving in the background matter. This method is based on the use of the modified Dirac equations for the particles wave functions, in which the correspondent effective potentials that account for the matter influence on particles are included. The developed approach establishes a basis for investigation of different phenomena which can arise when neutrinos and electrons move in dense media, including those peculiar for astrophysical and cosmological environments. The approach developed is similar to the Furry representation of quantum electrodynamics, widely used for description of particles interactions in the presence of external electromagnetic fields, and it works when a macroscopic amount of the background particles are confined within the scale of a neutrino or electron de Broglie wave lengths. We consider the modified Dirac equations for neutrinos (of both Dirac and Majorana types) and electrons having the standard model interactions with the background matter, however generalization to extensions of the standard model is just straightforward. To illustrate how the developed method works, we elaborate the quantum theories of the spin light of neutrino ($SLν$) and spin light of electron ($SLe$) in matter.

Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: We point out a general problem with the procedures commonly used to obtain improved actions from MCRG decimated configurations. Straightforward measurement of the couplings from the decimated configurations, by one of the known methods, can result into actions that do not correctly reproduce the physics on the undecimated lattice. This is because the decimated configurations are generally not representative of the equilibrium configurations of the assumed form of the effective action at the measured couplings. Curing this involves fine-tuning of the chosen MCRG decimation procedure, which is also dependent on the form assumed for the effective action. We illustrate this in decimation studies of the SU(2) LGT using Swendsen and Double Smeared Blocking decimation procedures. A single-plaquette improved action involving five group representations and free of this pathology is given.

description: Standard jet finding techniques used in elementary particle collisions have not been successful in the high track density of heavy-ion collisions. This paper describes a modified cone-type jet finding algorithm developed for the complex environment of heavy-ion collisions. The primary modification to the algorithm is the evaluation and subtraction of the large background energy, arising from uncorrelated soft hadrons, in each collision. A detailed analysis of the background energy and its event-by-event fluctuations has been performed on simulated data, and a method developed to estimate the background energy inside the jet cone from the measured energy outside the cone on an event-by-event basis. The algorithm has been tested using Monte-Carlo simulations of Pb+Pb collisions at $\sqrt{s}=5.5$ TeV for the ALICE detector at the LHC. The algorithm can reconstruct jets with a transverse energy of 50 GeV and above with an energy resolution of $\sim30%$.

description: In this paper, we examine the effectiveness of various recommendation strategies in the mobile channel and their impact on consumers' utility and demand levels for individual products. We find significant differences in effectiveness among various recommendation strategies. Interestingly, recommendation strategies that directly embed social proofs for the recommended alternatives outperform other recommendations. Besides, recommendation strategies combining social proofs with higher levels of induced awareness due to the prescribed temporal diversity have an even stronger effect on the mobile channel. In addition, we examine the heterogeneity of the demand effect across items, users, and contextual settings, further verifying empirically the aforementioned information and persuasion mechanisms and generating rich insights. We also facilitate the estimation of causal effects in the presence of endogeneity using machine-learning methods. Specifically, we develop novel econometric instruments that capture product differentiation (isolation) based on deep-learning models of user-generated reviews. Our empirical findings extend the current knowledge regarding the heterogeneous impact of recommender systems, reconcile contradictory prior results in the related literature, and have significant business implications.

White noise approach to the low density limit of a quantum particle in a gas
Creators: name: Pechen, Alexander
Publisher: name: arXiv
Year: 2006
Subjects: subject: Quantum Physics (quant-ph)
subject: Mathematical Physics (math-ph)

description: The white noise approach to the investigation of the dynamics of a quantum particle interacting with a dilute and in general non-equilibrium gaseous environment in the low density limit is outlined. The low density limit is the kinetic Markovian regime when only pair collisions (i.e., collisions of the test particle with one particle of the gas at one time moment) contribute to the dynamics. In the white noise approach one first proves that the appropriate operators describing the gas converge in the sense of appropriate matrix elements to certain operators of quantum white noise. Then these white noise operators are used to derive quantum white noise and quantum stochastic equations describing the approximate dynamics of the total system consisting of the particle and the gas. The derivation is given ab initio, starting from the exact microscopic quantum dynamics. The limiting dynamics is described by a quantum stochastic equation driven by a quantum Poisson process. This equation then applied to the derivation of quantum Langevin equation and linear Boltzmann equation for the reduced density matrix of the test particle. The first part of the paper describes the approach which was developed by L. Accardi, I.V. Volovich and the author and uses the Fock-antiFock (or GNS) representation for the CCR algebra of the gas. The second part presents the approach to the derivation of the limiting equations directly in terms of the correlation functions, without use of the Fock-antiFock representation. This approach simplifies the derivation and allows to express the strength of the quantum number process directly in terms of the one-particle $S$-matrix.

description: Young open clusters are ideal laboratories to understand star formation process. We present deep UBV I and Halpha photometry for the young open cluster IC 1590 in the center of the H II region NGC 281. Early-type members are selected from UBV photometric diagrams, and low-mass pre-main sequence (PMS) members are identified by using Halpha photometry. In addition, the published X-ray source list and Gaia astrometric data are also used to isolate probable members. A total of 408 stars are selected as members. The mean reddening obtained from early-type members is 1 M_sun). The signature of mass segregation is detected from the difference in the slopes of the initial mass functions for the inner (r < 2.'5) and outer region of this cluster. We finally discuss the star formation history in NGC 281.

description: We present a geometrical inspired study of the dynamics of $Dp$-branes. We focus on the usual nonpolynomial Dirac-Born-Infeld action for the worldvolume swept out by the brane in its evolution in general background spacetimes. We emphasize the form of the resulting equations of motion which are quite simple and resemble Newton's second law, complemented with a conservation law for a worldvolume bicurrent. We take a closer look at the classical Hamiltonian analysis which is supported by the ADM framework of general relativity. The constraints and their algebra are identified as well as the geometrical role they play in phase space. In order to illustrate our results, we review the dynamics of a $D1$-brane immersed in a $AdS_3 \times S^3$ background spacetime. We exhibit the mechanical properties of Born-Infeld objects paving the way to a consistent quantum formulation.

description: We derive the Schroedinger equation for a spinless charged particle constrained to a curved surface with electric and magnetics fields applied. The particle is confined on the surface using a thin-layer procedure, giving rise to the well-known geometric potential. The electric and magnetic fields are included via the four-potential. We find that there is no coupling between the fields and the surface curvature and that, with a proper choice of the gauge, the surface and transverse dynamics are exactly separable. Finally, the Hamiltonian for the cylinder, sphere and torus are analytically derived.

Geometrical and Algebraic Approach to Central Molecular Chirality: a Chirality Index and an Aufbau Description of Tetrahedral Molecules

Year: 2006
Subjects: subject: Chemical Physics (physics.chem-ph)

description: On the basis of empirical Fischer projections, we developed an algebraic approach to central molecular chirality of tetrahedral molecules. The elements of such an algebra are obtained from the 24 projections which a single chiral tetrahedron can generate in S and R absolute configurations. They constitute a matrix representation of the O(4) orthogonal group. According to this representation, given a molecule with n chiral centres, it is possible to define an index of chirality, where n is the number of stereogenic centres of the molecule and p the number of permutations observed under rotations and superimpositions of the tetrahedral molecule to its mirror image. The chirality index, not only assigns the global chirality of a given tetrahedral chain, but indicates also a way to predict the same property for new compounds, which can be consistently built up

Exploring the Representation of Word Meanings in Context: A Case Study on Homonymy and Synonymy
Creators: name: Garcia, Marcos
Publisher: name: arXiv
Year: 2021
Subjects: subject: Computation and Language (cs.CL)
subject: FOS: Computer and information sciences

description: This paper presents a multilingual study of word meaning representations in context. We assess the ability of both static and contextualized models to adequately represent different lexical-semantic relations, such as homonymy and synonymy. To do so, we created a new multilingual dataset that allows us to perform a controlled evaluation of several factors such as the impact of the surrounding context or the overlap between words, conveying the same or different senses. A systematic assessment on four scenarios shows that the best monolingual models based on Transformers can adequately disambiguate homonyms in context. However, as they rely heavily on context, these models fail at representing words with different senses when occurring in similar sentences. Experiments are performed in Galician, Portuguese, English, and Spanish, and both the dataset (with more than 3,000 evaluation items) and new models are freely released with this study.

description: Many problems of control theory can be solved through the evaluation-interpolation technique. In this dissertation it is presented the algorithms’ development via the evaluation-interpolation technique. In many problems the requested result might be either a polynomial or polynomial matrix or even a rational matrix. Through the “evaluation” we estimate the numerical values of the result an with the “interpolation” we retrieve the final result through polynomial and rational interpolation. In the first chapter, the implementation steps of the evaluation-interpolation technique are presented as well as the introductory notions of the polynomial and rational interpolation. In the second chapter, it is suggested algorithm determinant of the polynomial matrix. In the third chapter, the algorithm of the inverse rational matrix is suggested. In the fourth and fifth chapter the introductory notions of the generalized inverse are mentioned and algorithms of the generalized Moore-Penrose rational matrix and Drazin rational matrix respectively. In the sixth chapter it is suggested of the inverse rational matrix and Drazin rational matrix through rational interpolation.

quantum chemical methods

description: The reported work aims at implementation of a method allowing realistic simulation of large or extra-large biochemical systems (of 106 to 107 atoms) with first-principle quantum chemical methods. The current methods treat the whole system simultaneously. In this way the comput time increases rapidly with the size of the system and does not allow efficient parallelization of the calculations due to the mutual interactions between the electron density in all parts of the system. In order to avoid these problems we implemented a version of the Fragment Orbital Method (FMO) in which the whole system is divided into fragments calculated separately. This approach assures nearly linear scaling of the compute time with the size of the system and provides efficient parallelization of the job. The work includes development of pre- and post-processing components for automatic division of the system into monomers and reconstructing of the total energy and electron density of the whole system.

description: The Arecibo Galaxy Environment Survey (AGES) is one of several HI surveys utilising the new Arecibo L-band Feed Array (ALFA) fitted to the 305m radio telescope at Arecibo. The survey is specifically designed to investigate various galactic environments to higher sensitivity, higher velocity resolution and higher spatial resolution than previous fully sampled, 21 cm multibeam surveys. The emphasis is on making detailed observations of nearby objects although the large system bandwidth (100 MHz) will allow us to quantify the HI properties over a large instantaneous velocity range. In this paper we describe the survey and its goals and present the results from the precursor observations of a 5 degree x 1 degree region containing the nearby (~10 Mpc) NGC 628 group. We have detected all the group galaxies in the region including the low mass (M{HI}~10^7Mo) dwarf, dw0137+1541 (Briggs, 1986). The fluxes and velocities for these galaxies compare well with previously published data. There is no intra-group neutral gas detected down to a limiting column density of 2x10^{18}cm^{-2}.

description: This study investigated the effect of carbon sources (n = 2) on the performance of a microbial community in an anaerobic moving-bed biofilm reactor (MBBR) treating acid mine drainage (AMD). The 1.5 L anaerobic MBBR was operated across a range of hydraulic retention times –HRT’s (3–18 days), using different substrates, i.e. brewing wastewater and lactate as sole carbon sources and electron donors. Maximum sulphate reduction and chemical oxygen demand (COD) consumption rate was 21.94 and 24.28 mg SO2− 4 L−1 h−1, and 0.473 and 0.697 mg COD L−1 d−1for brewing wastewater and lactate supplemented bioreactors, respectively, at an HRT of 3 days. The maximum COD/SO2− 4 ratio was found to be 2.564 in the bioreactor supplemented with brewing wastewater at an HRT of 15 days. The metal removal above 70% in the system supplemented with brewing wastewater followed the order; Be2+ > Fe2+ > Sr2+ > Pb2+>Mg2+ > Cu2+ > Zn2+ > Li1+ > Ca2+ in comparison to the system supplemented with lactate, Be2+ > Fe2+ > Sr2+>Mg2+ > Cu2+ > Li1+ > Zn2+ > Pb2+ after an HRT of 18 days. Complete removal of beryllium (II) was observed irrespective of the carbon source used. The results clearly showed that brewing wastewater can be deployed as a nutritional supplement in environmental remediation of AMD.

description: We present the fabrication details of completely undoped electron-hole bilayer devices in a GaAs/AlGaAs double quantum well heterostructure with a 30 nm barrier. These devices have independently tunable densities of the two-dimensional electron gas and two-dimensional hole gas. We report four-terminal transport measurements of the independently contacted electron and hole layers with balanced densities from $1.2 \times 10^{11}$cm$^{-2}$ down to $4 \times 10^{10}$ cm$^{-2}$ at $T = 300 mK$. The mobilities can exceed $1 \times 10^{6}$ cm$^{2}$ V$^{-1}$ s$^{-1}$ for electrons and $4 \times 10^{5}$ cm$^{2}$ V$^{-1}$ s$^{-1}$ for holes.

description: We analyze a generalization of the quantum Calogero model with the underlying conformal symmetry, paying special attention to the two-body model deformation. Owing to the underlying $ SU(1,1) $ symmetry, we find that the analytic solutions of this model can be described within the scope of the Bargmann representation analysis and we investigate its dynamical structure by constructing the corresponding Fock space realization. The analysis from the standpoint of supersymmetric quantum mechanics (SUSYQM), when applied to this problem, reveals that the model is also shape invariant. For a certain range of the system parameters, the two-body generalization of the Calogero model is shown to admit a one-parameter family of self-adjoint extensions, leading to inequivalent quantizations of the system.

description: The British Library holds, in the legacy of John Wallis, six ciphered letters from the French Court to Count Lauzun in Ireland. Five of them, undecipherable by Wallis, were from Minister of War Louvois; their contents are still considered unknown today. However, not only is the plaintext copy of one of these letters held by the Service historique de la défense in Vincennes, but also is the nomenclator used for all five to be found in the Bibliothèque nationale de Paris. Another letter from Naval Minister Seignelay to Lauzun, which Wallis was able to decipher to a large extent, can be found in the Archives nationales de France. In this article, all six letters are published in plaintext, four of them possibly for the first time.
Quantum Fokker-Planck Modeling of Degenerate Electrons

description: An implicit and conservative numerical scheme is proposed for the isotropic quantum Fokker-Planck equation describing the evolution of degenerate electrons subject to elastic collisions with other electrons and ions. The electron-ion and electron-electron collision operators are discretized using a discontinuous Galerkin method, and the electron energy distribution is updated by an implicit time integration method. The numerical scheme is designed to satisfy all conservation laws exactly. Numerical tests and comparisons with other modeling approaches are shown to demonstrate the accuracy and conservation properties of the proposed method.
Using student-generated moral dilemmas to construct an objective measure of moral reasoning for intermediate elementary studies

Publisher: name: University of British Columbia
Year: 2009

description: This study employed a constructivistic approach to create a new objective measure of moral reasoning for use with intermediate grade, elementary students. Students rewrote three classic moral dilemmas used in Kohlberg's Moral Judgement Interview and rendered them more appealing and suitable for elementary students. From these rewritten dilemmas, a new measure of moral reasoning was constructed. One hundred and nine fifth, sixth and seventh grade students completed the new measure which consisted of ranking and rating statements corresponding to the stages of moral development for the three moral dilemmas. A Weighted Average Score was representing the pattern of percent stage usage was calculated for each student. Alpha coefficients for Inter-item consistency ranged fi"om .31 to .72 for the three different grade levels. Across all grade levels an alpha of .41 was found. Given the 3-item scale, this is not unusual. Internal consistency, as measured by Cronbach's alpha, was strongest for fifth grade students. The distribution of moral reasoning across the three levels of moral reasoning (i.e., preconventional, conventional, postconventional) revealed a consistent pattern of development. For example, pre-adolescents most frequently employed conventional reasoning and least often, postconventional reasoning. Results from an analysis of family composition and Weighted Average Scores revealed that students from non-intact families had higher moral reasoning scores than did students from intact famiUes. The disequilibrium or conflict associated with non-intact family status may promote moral reasoning growth resulting from the decision making and responsibility these students experience.

description: We report lifetimes, branching fractions, and the resulting oscillator strengths for transitions within the P II multiplet (3s^23p^2 ^3P - 3s^23p4s ^3P^o) at 1154 A. These beam-foil measurements represent the most comprehensive and precise set currently available experimentally. Comparison with earlier experimental and theoretical results is very good. Since Morton's most recent compilation is based on the earlier body of results, phosphorus abundances for interstellar material in our Galaxy and beyond derived from lambda 1154 do not require any revision.

description: We propose a distributed approach to train deep convolutional generative adversarial neural network (DC-CGANs) models. Our method reduces the imbalance between generator and discriminator by partitioning the training data according to data labels, and enhances scalability by performing a parallel training where multiple generators are concurrently trained, each one of them focusing on a single data label. Performance is assessed in terms of inception score and image quality on MNIST, CIFAR10, CIFAR100, and ImageNet1k datasets, showing a significant improvement in comparison to state-of-the-art techniques to training DC-CGANs. Weak scaling is attained on all the four datasets using up to 1,000 processes and 2,000 NVIDIA V100 GPUs on the OLCF supercomputer Summit.

description: Modifying the Kerr-Schild transformation used to generate black and white hole spacetimes, new dynamic black and white holes are obtained using a time-dependent Kerr-Schild scalar field. Physical solutions are found for black holes that shrink with time and for white holes that expand with time. The black hole spacetimes are physical only in the vicinity of the black hole, with the physical region increasing in radius with time. The white hole spacetimes are physical throughout. Unlike the standard Schwarzschild solution the singularities are non-isolated, since the time-dependence introduces a mass-energy distribution. The surfaces in the metrics where g_{tt}=g^{rr}=0 are dynamic, moving inward with time for the black holes and outward for the white holes, which leads to a question of whether these spacetimes truly have event horizons--a problem shared with Vaidya's cosmological black hole spacetimes. By finding a surface that shrinks or expands at the same rate as the null geodesics move, and within which null geodesics move inward or outward faster than the surfaces shrink or expand respectively, it is verified that these do in fact behave like black and white holes.

description: The anaerobic decomposition of coconut endosperm waste (CEW), residue derived from cooking, has been insidiously spewinggreenhouse gasses. Thus, the bioconversion of CEW via in situ fermentation by exo-microbes from commercial Rid-X andsubsequent valorization by black soldier fly larvae (BSFL) was the primary objective of the current study to gain sustainablelarval lipid and protein. Accordingly, various concentrations of exo-microbes were separately homogenized with CEW toperform fermentation amidst feeding to BSFL. It was found that 2.50% of exo-microbes was the threshold amount entailed toassuage competition between exo-microbes and BSFL for common nutrients. The presence of remnant nutrients exuded from the fermentation using 2.50% of exo-microbes was confirmed to promote BSFL growth measured as maximum larval weight gained and growth rate. Although the BSFL could accumulate the highest protein (16 mg/larva) upon feeding with CEW containing 2.50% of exo-microbes, more lipid (13 mg/larva) was stored in employing 0.10% of exo-microbes because of minimum loss to metabolic processes while prolonging the BSFL in its 5th instar stage.

description: Σκοπός της διπλωματικής εργασίας ήταν η παρουσίαση αφενός της αιτιολογίας των ποινικών αποφάσεων των δικαστηρίων και αφετέρου των αυτοτελών ισχυρισμών που προτείνονται στη διάρκεια μιας ποινικής δίκης. Η αιτιολογία όχι μόνο ως μια συνταγματική απαίτηση, η παραβίαση της οποίας γεννά πρόσφορο έδαφος για αναίρεση, αλλά και ως ένα καθημερινό στοίχημα του ελληνικού δικαστηριακού συστήματος με βάση τον όγκο των υποθέσεων, τους υπηρετούντες δικαστές και την ρεαλιστική δυνατότητα εκπλήρωσης της ουσίας της νομοθετικής επιταγής, παρουσιάζει ιδιαίτερο ενδιαφέρον και συχνά συναντά διάφορους ισχυρισμούς του κατηγορουμένου. Όταν λοιπόν κάποιοι από αυτούς τους ισχυρισμούς προταθούν ως αυτοτελείς, γίνονται πλέον κομμάτι της αιτιολογίας, δημιουργώντας υποχρέωση στο δικαστήριο ειδικής και εμπεριστατωμένης αιτιολογίας σε περίπτωση απόρριψής τους.
description: The purpose of this thesis was the presentation of the etiology of criminal judgments of the courts, as well as the presentation of the autonomous claims put forward during a criminal trial. The etiology not only as a constitutional requirement, the violation of which creates a breeding ground for cassation, but also as a daily wager of the Greek court system, based on the volume of cases, the serving judges and the realistic capability to fulfill the substance of the legislative requirement, is particularly interesting and frequently meets with various allegations of the accused. So when some of these allegations- claims are suggested as autonomous claims, they become a part of the etiology, creating an obligation to the court of specific and detailed reasoning in case of rejection.
