description: Las acciones judiciales que se adelantan en procura de la protección de los derechos de Propiedad Industrial y específicamente sobre las Marcas o con el fin de evitar comportamientos de competencia desleal, ante los Jueces Civiles de Circuito o la Superintendencia de Industria Comercio en ejercicio de facultades jurisdiccionales, se llevan a cabo bajo los procedimientos y normas adjetivas propias del Proceso Declarativo Verbal, reglado en el vigente Código General del Proceso. No obstante, siendo estas acciones asimismo previstas por normas sustanciales de carácter especial, se establecen en aquellas, ciertas particularidades adjetivas que influyen en la forma en que se desarrollan los procesos judiciales. En este orden de ideas, se presenta en este estudio un estado de la cuestión donde se indagan por un lado las generalidades de procedimiento propias del Proceso Declarativo Verbal y, de otro lado, las particularidades que se desprenden de las normas sustanciales referidas, entre estas, la Ley 256 de 1996 y de la Decisión 486 de 2000.
description: The legal actions brought before Civil Courts or the Superintendence of Industry and Commerce in exercise of their jurisdictional power, that are carried out to pursuit the protection of the Industrial Property rights, specifically Trademarks, or to prevent unfair competition behavior, are carried out under the procedures and adjectival rules of the Verbal Declaratory Process regulated in the current General Procedure Code. However, since these legal actions are also provided for by special substantive rules, certain adjectival particularities are established in those rules that influence the way in which the judicial proceedings are carried out. In this regard, this study provides, on the one hand, the procedural generalities of the Verbal Declaratory Process, and on the other hand, the particularities arising from the substantive rules referred to, among these, Law 256 of 1996 and Decision 486 of 2000.

El estudio concluye, que es inviable invocar nulidades procesales en los procedimientos de negociación de deudas debido a su incompatibilidad normativa, entonces, cuando un interviniente pretenda discutir un acto ilegal durante el procedimiento de negociación de deudas, esto se debe considerar como una controversia que se reprocha ante el juez civil municipal a través del trámite de las objeciones.
description: The purpose of this paper is to study the procedural nullities in the debt negotiation procedure of the non-trading natural person; it is based on the qualitative methodology that way tries to analyze the norm, the jurisprudence and the doctrine around the debt negotiation procedure and the regime of the procedural nullities. The study concludes that it is not feasible to invoke procedural nullities in debt negotiation proceedings due to their normative incompatibility, therefore, when an intervening party intends to discuss an illegal act during the debt negotiation proceedings, this must be considered as a controversy that is reproached before the municipal civil judge through the objections procedure.

description: This paper deals with the problem of function estimation. Using the white noise model setting, we provide a method to construct a new wavelet procedure based on thresholding rules which takes advantage of the dyadic structure of the wavelet decomposition. We prove that this new procedure performs very well since, on the one hand, it is adaptive and near-minimax over a large class of Besov spaces and, on the other hand, the maximal functional space (maxiset) where this procedure attains a given rate of convergence is very large. More than this, by studying the shape of its maxiset, we prove that the new procedure outperforms the hard thresholding procedure.

description: The large majority of extragalactic star cluster studies performed to date essentially use multi-colour photometry, combined with theoretical stellar synthesis models, to derive ages, masses, extinction estimates, and metallicities. M31 offers a unique laboratory for studies of globular cluster (GC) systems. In this paper, we obtain new age estimates for 91 M31 globular clusters, based on improved photometric data, updated theoretical stellar synthesis models and sophisticated new fitting methods. In particular, we used photometric measurements from the Two Micron All Sky Survey (2MASS), which, in combination with optical photometry, can partially break the well-known age-metallicity degeneracy operating at ages in excess of a few Gyr. We show robustly that previous age determinations based on photometric data were affected significantly by this age-metallicity degeneracy. Except for one cluster, the ages of our other sample GCs are all older than 1 Gyr. Their age distribution shows populations of young and intermediate-age GCs, peaking at $\sim3$ and 8 Gyr respectively, as well as the "usual" complement of well-known old GCs, i.e., GCs of similar age as the majority of the Galactic GCs. Our results also show that although there is significant scatter in metallicity at any age, there is a noticeable lack of young metal-poor and old metal-rich GCs, which might be indicative of an underlying age-metallicity relationship among the M31 GC population.

description: The potential field (PF) solution of the solar corona is a vital modeling tool for a wide range of applications, including minimum energy estimates, coronal magnetic field modeling, and empirical solar wind solutions. Given its popularity, it is important to understand how choices made in computing a PF may influence key properties of the solution. Here we study PF solutions for the global coronal magnetic field on 2012 June 13, computed with our high-performance finite difference code POT3D. Solutions are analyzed for their global properties and locally around NOAA AR 11504, using the net open flux, open field boundaries, total magnetic energy, and magnetic structure as metrics. We explore how PF solutions depend on 1) the data source, type, and processing of the inner boundary conditions, 2) the choice of the outer boundary condition height and type, and 3) the numerical resolution and spatial scale of information at the lower boundary. We discuss the various qualitative and quantitative differences that naturally arise by using different maps as input, and illustrate how coronal morphology and open flux depend most strongly on the outer boundary condition. We also show how large-scale morphologies and the open magnetic flux are remarkably insensitive to model resolution, while the surface mapping and embedded magnetic complexity vary considerably. This establishes important context for past, current, and future applications of the PF for coronal and solar wind modeling.

Así mismo se revela contrasta, el papel de los sistemas tributarios, con los ideales de un sistema óptimo. De acuerdo con lo anterior, se desarrolla una investigación de tipo cualitativa que ilustra, a través de un análisis comparado la descripción abierta de las realidades múltiples que viven ambas naciones. La investigación se concluye en una disertación sobre los beneficios tributarios como instrumentos de la política fiscal que influyen desde dos miradas.

Ειδικότερα, στο πρώτο κεφάλαιο της εργασίας εξετάζονται με τη σειρά οι εννέα συλλογές που συγκροτούν το εκδεδομένο έως σήμερα έργο του ποιητή –δηλαδή οι οκτώ συλλογές που εξέδωσε ο ίδιος και η μεταγενέστερη έκδοση των ανέκδοτων και αθησαύριστων ποιημάτων του– με απώτερο στόχο να αναδειχθούν τα ιδιαίτερα χαρακτηριστικά της ποιητικής ταυτότητας του Μανουσάκη. Εστιάζοντας στα κυριότερα σημεία της κάθε συλλογής ξεχωριστά, δίνεται παράλληλα η δυνατότητα να παρακολουθήσουμε τον τρόπο με τον οποίο διαμορφώνεται και εμπλουτίζεται με την πάροδο του χρόνου το έργο του ποιητή τόσο από άποψη θεματολογίας όσο και από άποψη εκφραστικής. Εν συνεχεία στο δεύτερο κεφάλαιο επιχειρείται μια επισκόπηση των κριτικών κειμένων που αφορούν το ποιητικό έργο του Μανουσάκη, προκειμένου να διαφανεί η στάση που κράτησε η κριτική απέναντι στο έργο του ποιητή από την έκδοση της πρώτης του συλλογής (1967) μέχρι και σήμερα
description: This paper focuses on poetry of Giorgis Manousakis, who is a contemporary Greek literary writer of the so called Second Postwar Generation, and furthermore centers on the reception of his work by critics. Specifically, the first chapter examines one by one the nine poetry books which comprise the so far published work of the poet, so as to highlight the characteristics of Manousakis' poetics. Emphasizing on each book's distinguished features separately, we simultaneously have the chance to examine issues of content and expression as they take shape during time. Afterwards, the second chapter offers an overview of the way that critics received Manousakis' poetry, since the time that the poet's first collection was published in 1967 until today
Planning policy responses to the challenge of industrial restructuring : the case of Vancouver, B.C.
Creators: name: Konkin, Barry G.
Publisher: name: University of British Columbia
Year: 2009

description: Urban centres around the world are experiencing the transition to what has been described as the ‘post-industrial’ economy, marked by the shift from traditional modes of industrial organization and production to new forms of activity, such as services and high technology industries. The changing nature of capital accumulation, urban space, industrial activities, and modes of economic organization have placed existing systems of urban and regional planning, zoning, and land use in doubt. As the urban area experiences the transition to the post-industrial era, the requirements for industrial activity in the city change, placing pressures on existing industrial land. In the initial stages of city development, a high level of traditional industrial activity is essential to provide the goods and services required for growth. As time passes,-the traditional industries appear less essential to the future growth of the city, and the emergent service oriented activities assume a more dominant role. This thesis will examine an alternative theoretical basis for planning theory and practice, and outline the current trends and patterns in industrial change through the examination of the restructuring responses in a ‘second order’ urban centre: Vancouver, British Columbia. Based on an examination of current theory regarding industrial change, a discussion of a series of zoning strategies suitable for planning industrial change will be presented.

description: The third and fourth degree collisional moments for $d$-dimensional inelastic Maxwell models are exactly evaluated in terms of the velocity moments, with explicit expressions for the associated eigenvalues and cross coefficients as functions of the coefficient of normal restitution. The results are applied to the analysis of the time evolution of the moments (scaled with the thermal speed) in the free cooling problem. It is observed that the characteristic relaxation time toward the homogeneous cooling state decreases as the anisotropy of the corresponding moment increases. In particular, in contrast to what happens in the one-dimensional case, all the anisotropic moments of degree equal to or less than four vanish in the homogeneous cooling state for $d\geq 2$.

description: I discuss constraints on the power spectrum of primordial tensor perturbations from a combination of Cosmic Microwave Background (CMB) measurements and the gravitational wave direct detection experiments LIGO/Virgo and DECIGO. There are two main points: (1) Inflation predicts an approximately power-law form for the primordial tensor spectrum, but makes no prediction for its amplitude. Given that neither Planck nor LIGO/Virgo has actually detected primordial tensor modes, it is trivially true that no model-independent constraint on the slope of the tensor power spectrum is possible with current data. (2) CMB and LIGO/Virgo scales differ by more than 19 orders of magnitude, and 16 for DECIGO. I show that a power-law extrapolation from CMB to direct detection frequencies overestimates the amplitude of primordial tensor modes by as much as two orders of magnitude relative to an ensemble of realistic single-field inflation models. Moreover, the primordial tensor amplitude at direct detection scales is mostly uncorrelated with the tensor spectral index at CMB scales, and any constraint is strongly dependent on the specific form of the inflationary potential.

description: We construct a pseudo-Lagrangian that is invariant under rigid $E_{11}$ and transforms as a density under $E_{11}$ generalised diffeomorphisms. The gauge-invariance requires the use of a section condition studied in previous work on $E_{11}$ exceptional field theory and the inclusion of constrained fields that transform in an indecomposable $E_{11}$-representation together with the $E_{11}$ coset fields. We show that, in combination with gauge-invariant and $E_{11}$-invariant duality equations, this pseudo-Lagrangian reduces to the bosonic sector of non-linear eleven-dimensional supergravity for one choice of solution to the section condition. For another choice, we reobtain the $E_8$ exceptional field theory and conjecture that our pseudo-Lagrangian and duality equations produce all exceptional field theories with maximal supersymmetry in any dimension. We also describe how the theory entails non-linear equations for higher dual fields, including the dual graviton in eleven dimensions. Furthermore, we speculate on the relation to the $E_{10}$ sigma model.

The design, construction and tests of an in situ capacitance moisture sensor and a portable capacitance moisture meter for organic soil and sawdust
Creators: name: Kra, Eric Y.
Publisher: name: University of British Columbia
Year: 2009

description: A capacitance chamber was constructed to measure the capacitance and hence the moisture content of a sawdust sample placed within it. Five readings of capacitance were taken for each sawdust moisture content level. The readings varied widely for each moisture content level suggesting some conditioning of the sample will be necessary if this type of chamber is used as an accurate alternative to the gravimetric oven method of moisture content determination. A simple in situ capacitance moisture meter was also designed and constructed. The device consisted of a 2.0 x3.0 xO.6 cm sensor and a hand-held digital multimeter with a capacitance range. The sensitivity of this moisture meter was compared to that of a commercially available fibreglass resistance type. In a series of experiments, two sensors (one of the capacitance type and one of the fiberglass resistance type) were installed in a different saturated soil and sawdust samples and the readings of the meters and weights of the samples were recorded at regular intervals. Of the two moisture meters, the capacitance moisture meter was found to be more sensitive to small changes in moisture content. With a few modifications (discussed in Chapter 5) to the sensor design, to improve accuracy, it is possible to monitor small changes in small volumes of organic soil and sawdust with this simple in situ capacitance moisture meter.

description: We study exact solutions of the infinite derivative gravity with null radiation which belong to the class of almost universal Weyl type III/N Kundt spacetimes. This class is defined by the property that all rank-2 tensors ${B_{ab}}$ constructed from the Riemann tensor and its covariant derivatives have traceless part of type N of the form $\mathcal{B}(\square)S_{ab}$ and the trace part constantly proportional to the metric. Here, $\mathcal{B}(\square)$ is an analytic operator and $S_{ab}$ is the traceless Ricci tensor. We show that the convoluted field equations reduce to a single non-local but linear equation, which contains only the Laplace operator $\triangle$ on 2-dimensional spaces of constant curvature. Such a non-local linear equation is always exactly solvable by eigenfunction expansion or using the heat kernel method for the non-local form-factor $\exp(-\ell^2\triangle)$ (with $\ell$ being the length scale of non-locality) as we demonstrate on several examples. We find the non-local analogues of the Aichelburg--Sexl and the Hotta--Tanaka solutions, which describe gravitational waves generated by null sources propagating in Minkowski, de Sitter, and anti-de Sitter spacetimes. They reduce to the solutions of the local theory far from the sources or in the local limit, ${\ell\to0}$. In the limit ${\ell\to\infty}$, they become conformally flat. We also discuss possible hints suggesting that the non-local solutions are regular at the locations of the sources in contrast to the local solutions; all curvature components in the natural null frame are finite and specifically the Weyl components vanish.

description: Previous calculation of spin torques for small-amplitude magnetization dynamics around a uniformly magnetized state [J. Phys. Soc. Jpn. {\bf 75} (2006) 113706] is extended here to the case of finite-amplitude dynamics. This is achieved by introducing an `` adiabatic'' spin frame for conduction electrons, and the associated SU(2) gauge field. In particular, the Gilbert damping is shown to arise from the time variation of the spin-relaxation source terms in this new frame, giving a new physical picture of the damping. The present method will allow a `` first-principle'' derivation of spin torques without any assumptions such as rotational symmetry in spin space.

description: Lazy evaluation is a powerful tool for functional programmers. It enables the concise expression of on-demand computation and a form of compositionality not available under other evaluation strategies. However, the stateful nature of lazy evaluation makes it hard to analyze a program's computational cost, either informally or formally. In this work, we present a novel and simple framework for formally reasoning about lazy computation costs based on a recent model of lazy evaluation: clairvoyant call-by-value. The key feature of our framework is its simplicity, as expressed by our definition of the clairvoyance monad. This monad is both simple to define (around 20 lines of Coq) and simple to reason about. We show that this monad can be effectively used to mechanically reason about the computational cost of lazy functional programs written in Coq.

description: Η παρούσα διπλωματική εργασία εξερευνά τεχνικές για την απεικόνιση δεδομένων κοινωνικών μέσων, με βασικό γνώμονα διαδικασίες ανάλυσης της δομής της αρχικής πληροφορίας και διαδικασίες σημασιολογικής ανάλυσης όρων, που προκύπτουν από τα κατηγορικά δεδομένα, τα οποία εντοπίζονται στο σύνολο της πληροφορίας. Η διερεύνηση των τεχνικών γίνεται με την ανάπτυξη ενός λειτουργικού πρότυπου συστήματος οπτικοποίησης, το οποίο υλοποιείται ως διαδικτυακή υπηρεσία ιστού με τμήματα λογισμικού που εκτελούνται σε περιβάλλον περιηγητή Ιστού (browser) και αυτόνομα τμήματα – υπηρεσίες μικρής κλίμακας (micro-services) - τα οποία εκτελούνται σε περιβάλλον διακομιστή (server side). Η λειτουργία τoυ συστήματος οπτικοποίησης βασίζεται στη διατήρηση ενός εσωτερικού μοντέλου αναπαράστασης, που προσαρμόζεται στα αρχικά δεδομένα και διατηρεί ένα πυρήνα σημασιολογικής πληροφορίας, ο οποίος χρησιμοποιείται σε όλα τα στάδια της οπτικοποίησης. Επίσης δίνεται έμφαση στην άντληση πληροφορίας από εξωτερικές πηγές (γράφους γνώσης όπως οι υπηρεσίες DBpedia και Wikidata, καθώς και από διεπαφές κοινωνικών δικτύων όπως το Twitter API). Επιπροσθέτως, δίνεται ιδιαίτερη έμφαση σε αυτόματους μηχανισμούς άντλησης γραφικών στοιχείων/συμβόλων από βιβλιοθήκη διανυσματικών γραφικών καθώς και χρωμάτων, τα οποία συνδέονται σημασιολογικά με τα κατηγορικά δεδομένα και χρησιμοποιούνται για να εμπλουτίσουν τις οπτικοποιήσεις
description: The present thesis explores techniques for the visualization of social media data, based on methods of structural analysis of the original information and semantic analysis of terms derived from the categorical data found in the input dataset. The exploration of these techniques is carried out by developing a functional visualization system that is implemented as a modern web service, with software segments running in a browser environment and autonomous micro-services executed in server side. The operation of the visualization system is based on the preservation of an internal representation model that adapts to the original data and maintains a semantic information core that is used through all the visualization stages. Also, emphasis is placed on extracting information from external sources (knowledge libraries such as DBpedia and Wikidata, as well as social networking interfaces such as the Twitter API). In addition, special emphasis is placed on mechanisms that retrieve automatically graphical assets/symbols from libraries of vector graphics and colors, which are semantically linked to the categorical data and are used to enrich visualizations

description: Research on formulae production in spreadsheets has established the practice as high risk yet unrecognised as such by industry. There are numerous software applications that are designed to audit formulae and find errors. However these are all post creation, designed to catch errors before the spreadsheet is deployed. As a general conclusion from EuSpRIG 2003 conference it was decided that the time has come to attempt novel solutions based on an understanding of human factors. Hence in this paper we examine one such possibility namely a novel example driven modelling approach. We discuss a control experiment that compares example driven modelling against traditional approaches over several progressively more difficult tests. The results are very interesting and certainly point to the value of further investigation of the example driven potential. Lastly we propose a method for statistically analysing the problem of overconfidence in spreadsheet modellers.

description: Crater chronologies are a fundamental tool to assess relative and absolute ages of planetary surfaces when direct radiometric dating is not available. Martian crater chronologies are derived from lunar crater spatial densities on terrains with known radiometric ages, and thus they critically depend on the extrapolation Moon to Mars. This extrapolation requires knowledge of the time evolution of the impact flux, including contributions from various impactor populations, factors that are not trivially connected to the dynamical evolution of the early Solar System. In this paper, we will present a new martian crater chronology based on current dynamical models, and consider the main sources of uncertainties. The new martian crater chronology is discussed using two interesting applications: Jezero crater's dark terrain (relevant to the NASA Mars 2020 mission) and the southern heavily cratered highlands.

description: The Peer-to-Peer systems (P2P) were led these last years as the major technology of access upon various resources on Internet. These systems build a cluster witch contains a very large number of peers. As the result the selection of peers who can answer for a given query is a very difficult problem. The efficiency of the selection algorithms can be improved by introducing of semantics into the process of queries routing. We present in this paper a novel improved version of our semantic routing algorithm LearningPeerSelection (LPS) presented in CORIA 2009, an incremental strategy of updating knowledge bases and an advanced experimental study. To test the proposed algorithm, we defined a layer of routing on the PeerSim simulator.

description: We construct a supersymmetric rotating black hole with asymptotically flat four-dimensional spacetime times a circle, by superposing an infinite number of BMPV black hole solutions at the same distance in one direction. The near horizon structure is the same as that of the five-dimensional BMPV black hole. The rotation of this black hole can exceed the Kerr bound in general relativity ($q\equiv a/G_4 M=1$), if the size is small.

description: In order to check on a recent suggestion that local scale invariance [M.Henkel et al. Phys.Rev.Lett. {\bf 87}, 265701 (2001)] might hold when the dynamics is of Gaussian nature, we have carried out the measurement of the response function in the kinetic Ising model with Glauber dynamics quenched to $T_C$ in $d=4$, where Gaussian behavior is expected to apply, and in the two other cases of the $d=2$ model quenched to $T_C$ and to below $T_C$, where instead deviations from Gaussian behavior are expected to appear. We find that in the $d=4$ case there is an excellent agreement between the numerical data, the local scale invariance prediction and the analytical Gaussian approximation. No logarithmic corrections are numerically detected. Conversely, in the $d=2$ cases, both in the quench to $T_C$ and to below $T_C$, sizable deviations of the local scale invariance behavior from the numerical data are observed. These results do support the idea that local scale invariance might miss to capture the non Gaussian features of the dynamics. The considerable precision needed for the comparison has been achieved through the use of a fast new algorithm for the measurement of the response function without applying the external field. From these high quality data we obtain $a=0.27 \pm 0.002$ for the scaling exponent of the response function in the $d=2$ Ising model quenched to below $T_C$, in agreement with previous results.

description: Κεντρικός άξονας της παρούσας εργασίας, είναι η μετατροπή ενός γραμμικού πολυμεταβλητού συστήματος αυτομάτου ελέγχου πολλών εισόδων και εξόδων σε σταθεροποιήσιμο. Συγκεκριμένα, δεδομένου ενός αυστηρώς κανονικού πίνακα συναρτήσεων μεταφοράς, αναζητούνται οι κανονικοί αντισταθμιστές ώστε να επιτευχθεί η σταθεροποίηση του αρχικού συστήματος μέσω τις επανατοποθέτησης επιθυμητών πόλων στον πίνακα συνάρτησης μεταφοράς του κλειστού συστήματος. Αρχικά, παρατίθενται κάποιες βασικές έννοιες και ορίζεται το μαθηματικό μοντέλο της διαδικασίας μέσω γραμμικών εξισώσεων, οι οποίες στη συνέχεια επιλύονται. Η διαδικασία αυτή υλοποιείται με χρήση του λογισμικού Matlab μέσω του γραφικού περιβάλλοντος GUI (Graphical User Interface) και της πολυωνυμικής εργαλειοθήκης polyx, όπου, δοσμένων των δεδομένων, δίνονται τα ζητούμενα αποτελέσματα.

description: The main purpose of this thesis is to transform a linear multivariable multi-input and multi-output automatic control system into a stabilizable one. More specifically, given a strictly proper transfer function matrix, the problem we face is to compute the proper compensators, so that the initial system will be stabilizable via desired poles placement to the transfer function matrix of the closed loop system. Firstly, the necessary concepts are given and the mathematical model of the process is defined through linear equations, which then are solved . The process is solved using the programming language Matlab, through the GUI (Graphical User Interface) and the polynomial toolbox polyx, where, given the data, the desired results were calculated. In the last part of this thesis, the method of using the application and the code of the algorithm is described

description: On étudie la covariance (pour la mesure de Gibbs) des spins en deux sites dans le cas d'un modèle de Sherrington--Kirkpatrick avec champ externe; lorsque le nombre de sites du modèle tend vers l'infini, une évaluation asymptotique des moments d'ordre $p$ de cette covariance permet d'obtenir un théorème limite faible avec une loi limite en général non gaussienne. We study the covariance (for Gibbs measure) of spins at two sites in the case of a Sherrington--Kirkpatrick model with an external field. When the number of sites of the model grows to infinity, an asymptotic evaluation of the $p$ moments of that covariance allows us to obtain a weak limit theorem, with a generally non-Gaussian limit law.

description: A pedigree is a directed graph in which each vertex (except the founder vertices) has two parents. The main result in this paper is a construction of an infinite family of counter examples to a reconstruction problem on pedigrees, thus negatively answering a question of Steel and Hein. Some positive reconstruction results are also presented. The problem of counting distinct (mutually non-isomorphic) pedigrees is considered. The known lower and upper bounds on the number of pedigrees are improved upon, and their relevance to pedigree reconstruction from DNA sequence data is discussed. It is shown that the information theoretic bound on the number of segregating sites in the sequence data that is minimally essential for reconstructing pedigrees would not significantly change with improved enumerative estimates.
