description: Following the seminal work of F. Bouchut on zero pressure gas dynamics which has been extensively used for gas particle-flows, the present contribution investigates quadrature-based velocity moments models for kinetic equations in the framework of the infinite Knudsen number limit, that is, for dilute clouds of small particles where the collision or coalescence probability asymptotically approaches zero. Such models define a hierarchy based on the number of moments and associated quadrature nodes, the first level of which leads to pressureless gas dynamics. We focus in particular on the four moment model where the flux closure is provided by a two-node quadrature in the velocity phase space and provide the right framework for studying both smooth and singular solutions. The link with both the kinetic underlying equation as well as with zero pressure gas dynamics is provided and we define the notion of measure solutions as well as the mathematical structure of the resulting system of four PDEs. We exhibit a family of entropies and entropy fluxes and define the notion of entropic solution. We study the Riemann problem and provide a series of entropic solutions in particular cases. This leads to a rigorous link with the possibility of the system of macroscopic PDEs to allow particle trajectory crossing (PTC) in the framework of smooth solutions. Generalized $δ$-choc solutions resulting from Riemann problem are also investigated. Finally, using a kinetic scheme proposed in the literature without mathematical background in several areas, we validate such a numerical approach in the framework of both smooth and singular solutions.

Characterization of ultramafic mine tailings reactivity for carbon capture and storage
Creators: name: Lu, Xueya
Publisher: name: University of British Columbia
Year: 2020

description: The carbon capture and storage potentials of ultramafic mine tailings are essential for assessing if mineral carbonation is a promising CO₂ sequestration strategy. CO₂ gas is mineralized in solid, stable carbonate minerals through dissolution and reaction with Mg-rich mining wastes. Here, the physical and chemical controls on reactivity and capacity for CO₂ sequestration in systems representative of mine tailings are examined using a combination of experimental techniques including flow-through, batch dissolution and disk carbonation. The reactivity of tailings is measured as a number of Mg²⁺ that is loosely bounded and readily leached (termed labile Mg). The study deploys the definition of labile Mg and understands its variability for advancing carbon sequestration techniques on the pilot and field scale. Flow-through and batch dissolution experiments on pure mineral phases and tailings show that labile Mg can be sourced from the bulk dissolution of Mg-hydroxides and the transient surface-reaction of Mg-silicates. Labile Mg is dependent primarily on mineralogy as well as the surrounding geochemical environment. CO₂ is the optimized acid that imposes a parallel and addictive effect towards promoting mineral dissolution and therefore enhances the quantity of labile Mg (reactivity). Characterizing mine tailings’ reactivity based on the capacity of labile Mg extraction is fundamental for accurate estimation of the carbon sequestration potential of the deposits and decisions on employment of the proper carbon sequestration techniques. This research imparts methods for quantitatively determine the reactivity of carbon capture and storage using mine tailings. Aspects of this research, such as serpentine surface-exchange reaction, also enabled more in-depth observations into the dissolution pathways of Mg-silicates and the feasibility of using ultramafic mine tailings for long-term carbon capture and storage.

description: Constraints on the Equation of State for symmetric matter (equal neutron and proton numbers) have been extracted from energetic collisions of heavy ions over a range of energies. Collisions of neutron-deficient and neutron-rich heavy ions now provide initial constraints on the EoS of neutron-rich matter at sub-saturation densities from isospin diffusions and neutron proton ratios. This article reviews the experimental constraints on the density dependence of Symmetry Energy at sub-saturation density.

description: In this work, considered methods to implement dialogue models using cognitive methods. The main task is to create a dialogue model that will provide the convenience of cognitive functions and can conduct a dialogue with the user in natural language. As a result of the study, a high degree of severity of behavior patterns was revealed, the typical structure of the modular language model was disassembled, and the quality of identifying signs of compliance with cognitive impairment was determined. In addition, a representation implementation scheme was developed, an ontology of the method for returning the received information was implemented, and a check of the agents performance for the implementation of a 3D simulator was proposed.

Determination of hidden variable models reproducing the spin-singlet
Creators: name: Di Lorenzo, Antonio
Publisher: name: arXiv
Year: 2011
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The experimental violation of Bell inequality establishes necessary but not sufficient conditions that any theory must obey. Namely, a theory compatible with the experimental observations can satisfy at most two of the three hypotheses at the basis of Bell's theorem: free will, no-signaling, and outcome-Independence. Quantum mechanics satisfies the first two hypotheses but not the latter. Experiments not only violate Bell inequality, but show an excellent agreement with quantum mechanics. This fact restricts further the class of admissible theories. In this work, the author determines the form of the hidden-variable models that reproduce the quantum mechanical predictions for a spin singlet while satisfying both the hypotheses of free will and no-signaling. Two classes of hidden-variable models are given as an example, and a general recipe to build infinitely many possible models is provided.

La caratteristica principale di questa tomba, che nel periodo di massimo splendore doveva essere molto suggestiva, è la polimatericità (pietre, metalli, dorature, campiture colorate). Lo scopo di questa tesi è stato quello di caratterizzare la tipologia di pigmenti e di bronzine utilizzati nella dipintura delle lastre in marmo della cappella e della cripta, e il legante in essi usato.

description: We study the problem of four-form flux quantization in F-theory compactifications. We prove that for smooth, elliptically fibered Calabi-Yau fourfolds with a Weierstrass representation, the flux is always integrally quantized. This implies that any possible half-integral quantization effects must come from 7-branes, i.e. from singularities of the fourfold. We subsequently analyze the quantization rule on explicit fourfolds with Sp(N) singularities, and connect our findings via Sen's limit to IIB string theory. Via direct computations we find that the four-form is half-integrally quantized whenever the corresponding 7-brane stacks wrap non-spin complex surfaces, in accordance with the perturbative Freed-Witten anomaly. Our calculations on the fourfolds are done via toric techniques, whereas in IIB we rely on Sen's tachyon condensation picture to treat bound states of branes. Finally, we give general formulae for the curvature- and flux-induced D3 tadpoles for general fourfolds with Sp(N) singularities.

description: We present a detailed study of the influence of various interactions on the spin quantum tunneling in a Mn12 wheel molecule. The effects of single-ion and exchange (spin-orbit) anisotropy are first considered, followed by an analysis of the roles played by secondary influences, e.g. disorder, dipolar and hyperfine fields, and magnetoacoustic interactions. Special attention is paid to the role of the antisymmetric Dzyaloshinski-Moriya (DM) interaction. This is done within the framework of a 12-spin microscopic model, and also using simplified dimer and tetramer approximations in which the electronic spins are grouped in 2 or 4 blocks, respectively. If the molecule is inversion symmetric, the DM interaction between the dimer halves must be zero. In an inversion symmetric tetramer, two independent DM vectors are allowed, but no new tunneling transitions are generated by the DM interaction. Experiments on the Mn12 wheel can only be explained if the molecular inversion symmetry is broken, and we explore this in detail using both models, focussing on the asymmetric disposition and rounding of Berry phase minima associated with quantum interference between states of opposite parity. A remarkable behavior exists for the `Berry phase zeroes' as a function of the directions of the internal DM vectors and the external transverse field. A rather drastic breaking of the molecular inversion-symmetry is required to explain the experiments; in the tetramer model this requires a reorientation of the DM vectors on one half of the molecule by nearly 180 degrees. This cannot be attributed to sample disorder. These results are of general interest for the quantum dynamics of tunneling spins, and lead to some interesting experimental predictions.

description: One of the most important factors in determining the stellar lithium abundance is the effective temperature. In a previous study by the authors, new effective temperatures Teff for sixteen metal-poor halo dwarfs were derived using a local thermodynamic equilibrium (LTE) description of the formation of Fe lines. This new Teff scale reinforced the discrepancy. For six of the stars from our previous study we calculate revised temperatures using a non-local thermodynamic equilibrium (NLTE) approach. These are then used to derive a new mean primordial lithium abundance in an attempt to solve the lithium discrepancy. Using the code MULTI we calculate NLTE corrections to the LTE abundances for the Fe I lines measured in the six stars, and determine new Teff's. We keep other physical parameters, i.e. log g, [Fe/H] and xi, constant at the values calculated in Paper I. With the revised Teff scale we derive new Li abundances. We compare the NLTE values of Teff with the photometric temperatures of Ryan et al. (1999, ApJ, 523, 654), the infrared flux method (IRFM) temperatures of Melendez & Ramirez (2004, ApJ, 615, 33), and the Balmer line wing temperatures of Asplund et al. (2006, ApJ, 644, 229). We find that our temperatures are hotter than both the Ryan et al. and Asplund et al. temperatures by typically ~ 110 K - 160 K, but are still cooler than the temperatures of Melendez & Ramirez by typically ~ 190 K. The temperatures imply a primordial Li abundance of 2.19 dex or 2.21 dex, depending on the magnitude of collisions with hydrogen in the calculations, still well below the value of 2.72 dex inferred from WMAP + BBN. We discuss the effects of collisions on trends of 7Li abundances with [Fe/H] and Teff, as well as the NLTE effects on the determination of log g through ionization equilibrium, which imply a collisional scaling factor SH > 1 for collisions between Fe and H atoms.

description: La ricerca presentata si sviluppa principalmente a partire da due domande. La prima si impegna ad indagare da quali elementi è contraddistinta la rappresentazione che i bambini hanno del percorso casa-scuola e da cosa sono influenzati. La seconda domanda è riferita alla metodologia di lavoro utilizzata per capire quali sono le strategie che il docente deve saper mettere in atto per favorire lo sviluppo delle competenze e delle conoscenze del bambino. Quanto emerso con e dai bambini è stato raccolto in un libro personale che da subito ha creato un forte legame affettivo. Un libro visto anche come valigia metaforica a due facce, dove da una parte vi è la possibilità di conoscere il bambino e la sua casa e dall’altra la strada che il bambino percorre per raggiungere la Scuola dell’Infanzia. Tramite strumenti di ricerca quali le interviste, le fotografie e i collage e grazie a momenti di narrazione privilegiati si è potuto verificare e confermare quanto i bambini siano già attenti e pienamente consapevoli del mondo che li circonda, dimostrando una forte sensibilità nel loro sguardo che aspetta solo l’occasione per essere raccontato. La metodologia di lavoro sperimentata ha dato ai bambini grande spazio di narrazione e di creazione rispettando i loro tempi e permettendo loro di sviluppare maggiormente la propria autonomia e la propria creatività.

description: We provide a dynamic programming principle for stochastic optimal control problems with expectation constraints. A weak formulation, using test functions and a probabilistic relaxation of the constraint, avoids restrictions related to a measurable selection but still implies the Hamilton-Jacobi-Bellman equation in the viscosity sense. We treat open state constraints as a special case of expectation constraints and prove a comparison theorem to obtain the equation for closed state constraints.

Epistemic (mis)alignment in discourse : what Spanish discourse markers reveal
Creators: name: Osa Gómez Del Campo, Adriana
Publisher: name: University of British Columbia
Year: 2020

description: In this dissertation, I explore how speakers of Peninsular Spanish keep epistemic alignment during a conversation by using two discourse markers: sentence initial 'si' and sentence final 'no' (Ortega, 1985; Montolío Durán, 1999; Schwenter, 2000b; Montañez Mesas, 2015; Schwenter, 2016b). I show that these two discourse markers operate at different conversational levels: 'si' keeps an alignment in the set of shared, public propositions, whereas 'no' keeps an alignment between the information states of the interlocutors. First, I focus on 'si' and its distribution. I show that 'si' is an illocutionary operator that marks that a proposition was already known by all interlocutors, hence forcing an alignment within the Common Ground. The sentence in which 'si' occurs is used in the conversation to reject the previous contribution due to a violation of a felicity condition. I use 'si' to show that speakers have two versions of the Common Ground: one representing what they themselves know, and the other representing what they believe the Addressee to know. I also discuss the distribution of 'no', which is used to align both beliefs and outcomes among interlocutors. It does so by requesting confirmation from the Addressee that the contextual update proposed by the Speaker is shareable and public. The sentence in which 'no' occurs is used in the conversation to confirm a bias held by the Speaker, either with respect to a belief or an outcome that is preferred. Finally, I offer a syntactic analysis of both discourse markers. I adopt an analysis based on proposals to include utterance-level information in the left periphery. I propose that 'si' is an illocutionary operator situated within the Complementizer Phrase, as high as ForceP, based on prosodic and syntactic evidence. I propose that 'no' occupies an even higher position, outside of Complementizer Phrase but still within the same clause. I follow recent analyses in the syntactic literature in calling this higher structure the Grounding layer (Thoma, 2016; Wiltschko and Heim, 2016). Within it, 'no' occupies the layer that represents the Addressee’s information state (as perceived by the Speaker).

description: Questo lavoro mira ad analizzare l’impatto dell’uso didattico del video sulle abilità di ascolto e comprensione in lingua inglese, verificando se una frequente esposizione ad attività che integrano la visione guidata di video influisca sul miglioramento dei risultati d’apprendimento. Vengono valutate anche le percezioni degli allievi dei video, delle modalità d’uso, e dell’utilizzo di questo strumento in classe in termini di apprezzamento e utilità. Nella prima parte del lavoro si considerano gli elementi utili per progettare l’insegnamento con materiale video e sfruttare al meglio il suo potenziale. Le attività proposte comprendono una fase di pre-listening, durante la quale gli allievi familiarizzano con diverse tecniche di visualizzazione e svolgono vari esercizi volti a facilitare l’ascolto, e un test da svolgere durante la visione che verifica la comprensione orale. La percezione degli studenti viene valutata tramite dei questionari somministrati al termine delle attività e alla fine del percorso. Dai risultati si nota un’evoluzione non costante nel miglioramento degli allievi, tuttavia l’impatto complessivo sulle loro abilità di ascolto è positivo. La maggioranza degli studenti dimostra interesse per l’uso dei video e ritiene le attività utili per migliorare le loro abilità di ascolto. Relatore: Luca Botturi.
La statistica in geografia

description: Per comprendere la complessità delle informazioni e dei documenti che ci circondano è necessario avere degli strumenti d’analisi. Un approccio più matematico alla geografia potrebbe essere una possibile soluzione. Nel caso specifico è stato realizzato in una classe di IV media un itinerario didattico di geografia sulla statistica descrittiva, allo scopo di valutare se una conoscenza più approfondita degli strumenti matematici, in particolare degli indici di posizione e di dispersione (moda, mediana, media, diversità e scarto), permettano agli allievi di acquisire un metodo di lavoro e di essere più critici di fronte a tabelle, grafici e carte tematiche. Per fare questo si è deciso di analizzare i materiali prodotti in classe dagli allievi prima e dopo l’intervento in classe. Alla fine del percorso si è notato che gli allievi hanno appreso un metodo di analisi dei dati, e hanno imparato a calcolare gli indici di posizione e di variabilità dando loro un significato, anche se purtroppo molti di loro non sono riusciti a utilizzarli per criticare in modo costruttivo altre fonti. Quindi matematica e geografia sono due materie così diverse ma così vicine tra loro, e un lavoro interdisciplinare riesce a dimostrarlo. Relatore: Marco Lupatini. Materie: matematica e geografia

description: We investigate a tight-binding model of the octahedron-decorated cubic lattice with spin-orbit coupling. We calculate the band structure of the lattice and evaluate the Z_2 topological indices. According to the Z_2 topological indices and the band structure, we present the phase diagrams of the lattice with different filling fractions. We find that the $(1;111)$ and $(1;000)$ strong topological insulators occur in some range of parameters at 1/6, 1/2 and 2/3 filling fractions. Additionally, the $(0;111)$ weak topological insulator is found at 1/6 and 2/3 filing fractions. We analyze and discuss the characteristics of these topological insulators and their surfaces states.
Self Consistent Models of the Solar Wind

description: The origins of the hot solar corona and the supersonically expanding solar wind are still the subject of much debate. This paper summarizes some of the essential ingredients of realistic and self-consistent models of solar wind acceleration. It also outlines the major issues in the recent debate over what physical processes dominate the mass, momentum, and energy balance in the accelerating wind. A key obstacle in the way of producing realistic simulations of the Sun-heliosphere system is the lack of a physically motivated way of specifying the coronal heating rate. Recent models that assume the energy comes from Alfven waves that are partially reflected, and then dissipated by magnetohydrodynamic turbulence, have been found to reproduce many of the observed features of the solar wind. This paper discusses results from these models, including detailed comparisons with measured plasma properties as a function of solar wind speed. Some suggestions are also given for future work that could answer the many remaining questions about coronal heating and solar wind acceleration.

Investigating the change processes in information systems requirements
Creators: name: Taghavi, Atefeh
Publisher: name: University of British Columbia
Year: 2020

description: Success of information systems (IS) projects is deeply dependent on the quality of the requirements informing their design. Specifically, if the requirements are not precisely determined, IS cannot meet the business needs of organizations. One of the most enduring challenges in managing requirements is ongoing change in requirements. Changes emerge due to various reasons. The main goal of this dissertation is to shed more light on change drivers and change processes in IS requirements. To achieve this goal, we conduct three separate but interdependent studies. The first study elicits and synthesizes various change drivers from the extant literature. By employing a design science research methodology, we propose the Socio-Technical Change Framework and Socio-Technical Requirements Change Method. These two artifacts are drawing upon models in socio-technical systems studies. The proposed framework elaborates on how various social and technical change drivers jointly develop the changes in requirements. The proposed method also provides IS analysts with a new solution to anticipate potential future changes in requirements. The second study investigates the change drivers in contemporary IS projects. We approach this study from a qualitative research methodology. The results from the interviews and surveys reveal 14 categories of change drivers. These change drivers are similar to the change drivers in the first study. However, we explore that the contemporary context includes interesting unique characteristics, which moderate the change processes in IS requirements. The third study dives more deeply into some of the findings from the second study. Specifically, we examine how two of the important change drivers — changes in the environment and changes in user expectations — and one prominent characteristic of contemporary projects — interdependency between requirements — jointly influence the final changes in requirements. To address this query, we employ an agent-based simulation model. We explore interesting insights into the impact of the interdependency between requirements and learning patterns of the population on requirements change. In sum, the findings of all three studies contribute to the extant body of knowledge in IS requirements and open interesting avenues for future research. They also have practical implications for IS analysts, project managers, business owners, and third-party vendors.

description: We propose an NMF (Nonnegative Matrix Factorization)-based approach in collaborative filtering based recommendation systems to improve the Cold-Start-Users predictions since Cold-Start-Users suffer from high error in the results. The proposed method utilizes the trust network information to impute a subset of the missing ratings before NMF is applied. We proposed three strategies to select the subset of missing ratings to impute in order to examine the influence of the imputation with both item groups: Cold-Start-Items and Heavy-Rated-Items; and survey if the trustees' ratings could improve the results more than the other users. We analyze two factors that may affect results of the imputation: (1) the total number of imputed ratings, and (2) the average of imputed rating values. Experiments on four different datasets are conducted to examine the proposed approach. The results show that our approach improves the predicted rating of the cold-start users and alleviates the impact of imputed ratings.

description: We examine the changeover in the particle configurations and the dynamics in dense Lennard-Jones binary mixtures composed of small and large particles. By varying the composition at a low temperature, we realize crystal with defects, polycrystal with small grains, and glass with various degrees of disorder. In particular, we show configurations where small crystalline regions composed of the majority species are enclosed by percolated amorphous layers composed of the two species. We visualize the dynamics of configuration changes using the method of bond breakage and following the particle displacements. In quiescent jammed states, the dynamics is severely slowed down and is highly heterogeneous at any compositions. In shear, plastic deformations multiply occur in relatively fragile regions, growing into large-scale shear bands where the strain is highly localized. Such bands appear on short time scales and change on long time scales with finite life times.
