En la presenteinvestigación se estudia el desplazamiento auxiliar que ocurrió en el español, es decir, el proceso mediante el cual frente a la posibilidad de usar dos auxiliares para formar tiempos compuestos (ser y haber) hoy en día solo existe haber, siendo desplazado el auxiliar ser de esta finalidad. El estudio de este fenómeno está enfocado en comprobar/refutar la pertinencia de la Auxiliary Selection Hierarchy de Antonella Sorace (2000)para el caso del español, la cual plantea que el desplazamiento auxiliar se da ordenadamente y que los verbos con telicidad inherente fueron aquellos que más resisitieron el desplazamiento. Una de lasprincipales críticas que se realiza a la propuesta de Sorace es que las categorías con las que trabaja carecen de rasgos formales que las diferencien claramente. Debido a esto, también se toman otras dos teorías con las cuales se estudia el desplazamiento auxiliar: la de Vendler (1967) y la de Cuartero (2006) para el caso de los verbos de movimiento. El análisis se realiza con un corpus compilado por Rosemeyer (2016) de textos españoles datados entre los siglos XIII y XVII. Los resultados indican que en términos generales, la telicidad sí es un fenómeno que ordena el desplazamiento auxiliar. También fue posible concluir que la composicionalidad de la sintaxis y la aparición de la partícula se juegan un rol importante en el desplazamiento.

The paper presents an Markov Chain Monte Carlo algorithm for both variable and covariance selection in the context of logistic mixed effects models. This algorithm allows us to sample solely from standard densities, with no additional tuning being needed. We apply a stochastic search variable approach to select explanatory variables as well as to determine the structure of the random effects covariance matrix. For logistic mixed effects models prior determination of explanatory variables and random effects is no longer prerequisite since the definite structure is chosen in a data-driven manner in the course of the modeling procedure. As an illustration two real-data examples from finance and tourism studies are given. (author's abstract)

The nuclear fusion is a type of energy source that is very clean and technically limitless. ITER will be the first milestone along the road toward the production of fusion energy. It will be an experimental reactor that will prove the feasibility of technologies and its results will be helpful for the future steps. Among the technologies that will be tested in ITER, a particular interest is referred to the possibility of tritium breeding thus making the fuel for the reaction inexhaustible. The European studies for this type of technology are focused on a system denominated WCLL-TBM. The aim of this thesis is the definition and commercial selection of instrumentation of two of the six ancillary systems that support the WCLL-TBM. Obviously, it is not expected that a complete mapping of the instrumentation will be available at the end of this activity. So, the final output requested by NIER Ingegneria, the company through which the internship activities were carried out, is the collection of all the actions taken to find suitable commercial models. Firstly, a brief analysis is used to describe the ancillary systems considered in which the instruments are located: this is the identification phase. This is followed by the phase where instruments are defined in terms of their required properties. Both standard properties have been considered during the definition of an instrument, as well as those specific to the nuclear application. The instruments are then classified based on defined criteria, grouping instruments with similar properties. In this way a low number of instruments is searched on the market. The selection phase concludes the process: a series of possible suppliers have been identified and contacted to obtain specific models that can be suitable. As final output, a specific check regarding required properties and the ones of the commercial models is performed. At the end, the global view of the results obtained, and the open action are highlighted.

This study has both a theoretical and a methodological dimension. Theoretically, it is concerned with variation and indeterminacy in linguistic acceptability judgments. Methodologically, it involves the application of a rigorous procedure for the elicitation of judgment data that is sensitive to informants' variable or indeterminate intuitions. The theoretical focus is on the linguistic intuitions of native and non-native speakers of Italian about a number of grammatical phenomena related to the choice between the auxiliaries ESSERE ('be') and AVERE ('have') with non-transitive (unaccusative and unergative) verbs. It is argued that a purely syntactic account of unaccusativity is insufficient to capture the variation exhibited by these verbs. In particular, it is claimed that the unmarked selection of ESSERE with unaccusatives and of AVERE with unergatives in the present perfect tense is sensitive not only to a hierarchy of syntactic configurations (as assumed by the Government-Binding version of the Unaccusativity Hypothesis) but also to lexical hierarchies that subdivide the range of unaccusative and unergative verbs along semantic dimensions. Such hierarchies distinguish 'core', or prototypical, types of verbs from peripheral ones, and are consistent with the historical evolution of auxiliaries in Romance. However, auxiliary selection in syntactically marked 'restructuring' constructions, induced by certain Raising and Control verbs, is not sensitive to these semantic dimensions. It was predicted that the interaction between syntactic and semantic constraints would give rise to systematic variability in native speakers' linguistic intuitions, manifested in consistent and determinate acceptability judgments on core types of verbs, and variable or indeterminate judgments on peripheral types of verbs. It was also predicted that non-natives would differ from natives in terms of the extent to which indeterminate judgments penetrated from the periphery to the core.

Cette thèse examine le phénomène complexe de la sélection des auxiliaires dans deux langues romanes, à savoir l'italien et le français. L'objectif principal est d'élucider les facteurs qui influencent le choix entre les auxiliaires être et avoir dans la formation du passé composé. L'étude se concentre sur les verbes susceptibles de sélectionner les deux auxiliaires, communément appelés verbes périphériques (Sorace 2000), qui, malgré de nombreuses analyses individuelles, n'ont pas été étudiés de manière exhaustive (Giancarli 2015). Les questions de recherche centrales sont les suivantes : quelles caractéristiques permettent à ces verbes de sélectionner les deux auxiliaires ? Quels facteurs déterminent la prédominance d'un auxiliaire par rapport à l'autre ? Quel est le poids relatif des facteurs tels que l'agentivité et la télicité dans le choix des auxiliaires (Sorace 2000) ? Pour la première fois, cette recherche explore systématiquement la sélection des auxiliaires en italien et en français en utilisant l'analyse de corpus et le traitement automatique des langues (TAL). En intégrant ces méthodes, l'étude vise à identifier les facteurs les plus significatifs influençant le choix des auxiliaires pour les verbes intransitifs présentant une double auxiliaire. La recherche combine une analyse qualitative d'occurrences annotées manuellement à partir de SketchEngine (Kilgarriff et al., 2014) avec une analyse quantitative basée sur des modèles statistiques pour déterminer les paramètres les plus importants dans la sélection des auxiliaires. Les résultats révèlent l'importance primordiale des aspects sémantiques, syntaxiques et morphologiques dans le choix entre être et avoir. Notamment, la télicité s'avère moins pertinente pour ces verbes. L'étude met également en lumière des différences significatives entre l'italien et le français. En italien, les verbes sont catégorisés en verbes pleins et semi-auxiliaires. Pour les verbes pleins, la cause interne et les traits humains constituent des facteurs cruciaux dans la sélection des auxiliaires. Pour les verbes semi-auxiliaires, le type d'infinitif et les traits humains associés à certains infinitifs se révèlent significatifs. En français, le type de construction joue un rôle déterminant dans le choix de l'auxiliaire. En apportant des réponses approfondies à des questions encore peu explorées, cette étude s'aligne sur les travaux existants tout en les enrichissant. Elle améliore considérablement notre compréhension de la catégorisation des verbes et de la sélection des auxiliaires, avec des implications majeures pour la linguistique théorique et appliquée. De plus, elle souligne l'importance des approches méthodologiques intégratives dans l'analyse des phénomènes linguistiques complexes
This thesis investigates the intricate phenomenon of auxiliary selection in two Romance languages, namely Italian and French. The primary objective is to elucidate the factors that influence the choice between the auxiliaries ‘be' and ‘have' in the formation of the perfect tense. The study focuses on verbs that can select both auxiliaries, commonly known as peripheral verbs (Sorace 2000), which, despite extensive individual examination, have not been comprehensively analyzed (Giancarli 2015).The central research questions addressed are: What characteristics enable these verbs to select both auxiliaries? Which factors determine the predominance of one auxiliary over the other? What is the relative weight of factors such as agentivity and telicity in auxiliary selection (Sorace 2000)? For the first time, this research systematically explores auxiliary selection in Italian and French using corpus analysis and natural language processing (NLP). By integrating these methods, the study aims to identify the most significant factors influencing auxiliary choice in intransitive verbs with double auxiliation. The research combines qualitative analysis of manually annotated occurrences from SketchEngine (Kilgarriff et al., 2014) with quantitative analysis using statistical models to determine the most significant parameters in auxiliary selection. The findings reveal the paramount importance of semantic, syntactic, and morphological aspects in the choice of ‘be' or ‘have'. Notably, telicity is found to be less relevant for these verbs. The study also highlights significant differences between Italian and French. Italian verbs are categorized into full verbs and semi-auxiliaries. For full verbs, internal cause and human traits are crucial factors in auxiliary selection. For semi-auxiliary verbs, the type of infinitive and the human trait associated with particular infinitives are shown to be significant. In French, the type of construction heavily influences auxiliary choice.By providing comprehensive answers to previously unexplored areas, this study aligns with and extends the existing literature. It significantly enhances our understanding of verb categorization and auxiliary selection, with substantial implications for both theoretical and applied linguistics. Furthermore, it underscores the importance of integrative methodological approaches for analyzing complex linguistic phenomena

Métodos tradicionais de seleção de portfólio de projetos tendem a privilegiar dimensões e aspectos mais relacionados ao lucro e/ou crescimento. Além dessas dimensões e aspectos, Institutos Públicos podem se orientar por aspectos de dimensões que, a exemplo da social, são menos passíveis de avaliação objetiva. Isso justifica a conveniência de instrumentos auxiliares aos processos de seleção de projetos organizados a partir de prioridades não coincidentes com aquelas que comumente orientam empresas privadas. A proposição desta tese foi sistematizar um instrumento auxiliar aos métodos de seleção de projetos de P&D em Institutos Públicos. Trata-se da sistematização de relações em algoritmo que possibilita e valoriza as manifestações de entendimentos orientados primordialmente por diferentes dimensões que fundamentam a missão institucional. O instrumento auxiliar proposto se revelou efetivo em atender as diversas dimensões que orientam um Instituto Público, e compatível com a dinâmica operacional de modelos tradicionais de seleção de projetos e de gestão de portfólio de projetos. Essa efetividade e a compatibilidade operacional foram verificadas com base em uma simulação de seleção realizada a partir de projetos já componentes do portfólio de um Instituto Público. O ranqueamento dos projetos resultou diferente daquele produzido em procedimento comumente utilizado pelo instituto. Conclui-se que, ainda que somente auxiliar aos modelos tradicionais de seleção de projetos, o instrumento proposto pode concorrer para processos de seleção que melhor considerem as múltiplas dimensões e diferentes perspectivas presentes na gestão de Institutos Públicos.
Traditional project portfolio selection methods tend to confer greater privilege to profit and/or outgrowth than to other dimensions and aspects; however, public institutes have some different dimensions, such as social development, that go beyond the economic and financial aspects to ground the institutional mission. This context is appropriate for complementary selection methods or based on different priorities from private companies methods. This thesis proposes to systematize an auxiliary instrument for R&D projects selection processes, aiming to better meet Public Institutes needs. The systematization of relations, calculated by an algorithm, enables and valorizes the manifested understanding driven by different dimensions that underlie the institutional mission. The proposed auxiliary instrument proved to be effective to better meet the diverse dimensions that drive a Public Institute, and to be fully compatible with the operational dynamics of traditional models for project selection and project portfolio management. Such effectiveness and operational compatibility were checked using a project selection simulation of projects from a Public Institute portfolio. The ranking of the portfolio resulted differently from the procedure commonly used by the Institute. In summary, although the instrument proposed is only complementary to traditional methods of project selection, it can contribute to project selection processes that better consider different perspectives and multiple dimensions that characterize Public Institutes management.

This study focuses on factors that affect the structural integrity of wood-based composites. Wood-based composites exposed to fire may decompose due to the elevated temperatures, resulting in a degradation in performance. Thermal modelling can only predict the structural integrity of construction materials in fire if it is given accurate inputs. Consequently, methods for the characterization of the thermal, physical, and mechanical behaviors of wood and wood-based composites are selected, designed, and benchmarked. The relevant thermal and physical responses characterized includes porosity, permeability and thermal diffusivity. Common construction materials (white pine board, medium density fiberboard and spruce 24) are characterized from room temperature to complete decomposition. The characterization techniques and processes are based on existing literature and relevant ASTM standards. To reduce the number of experiments required for future material characterization, estimates based upon the degree of decomposition and the measured values for the virgin and charred materials are used. For porosity and thermal diffusivity, these models allow values at intermediate temperatures to be estimated with measurements at room temperature and complete decomposition and thermogravimetric analysis (TGA). We find that permeability depends heavily on the microstructure of materials and should be measured independently at the conditions of interest. An additional important aspect of the performance of wood-based composites is the fracture behavior of wood/adhesive systems. Adhesive bonding enables many engineered wood products such as furniture and structural wood joints and the adhesive fracture toughness often determines the durability. The conventional characterization method for wood/adhesive fracture resistance relies on samples with machined grain angles designed to funnel cracks to the adhesive interface. This method of sample preparation is difficult and time-consuming for certain wood species. In this work, a practical and efficient method is developed to characterize adhesive fracture energy of adhesively bonded veneer systems. In the method, auxiliary aluminum adherends are bonded to the veneers in an effort to drive the crack to the wood/adhesive interface. The method is applied to rotary-peeled veneers and saw-cut veneers produced from three species of wood bonded with three commonly used adhesives. The new tests method yields a high interfacial failure rate and successfully identifies differences in the performance of the three adhesives. SPG (one species of the rotary-peeled veneers) demonstrates a rising R-curve behavior (an increase in the fracture toughness with crack length) when bonded on the loose side. This increase in fracture toughness is observed to be a result of adhesive-substrate interaction, which is a developing process zone behind the crack tip consisting of bridged wood ligaments.

Construction materials exposed to elevated temperatures from fires may reach temperatures where the material decomposes from the original material to a char. Protected and unprotected structural timber products exposed to fires may exhibit this behavior resulting in a degradation of performance. Understanding the thermal and physical responses of these materials is crucial in evaluating the materials behavior in fire. Additionally, many wood-based products (such as furniture) rely on adhesive bonds. Consequently, their usefulness is determined by the performance of those bonds. In this work, methods are developed to measure key properties impacting the behavior of wood-based systems at elevated temperatures, such as that experienced in fires and when they are subjected to forces attempting to debond one wood material from another. These techniques are demonstrated on common building materials (white pine board, medium density fiberboard and spruce 24) and wood veneers from three different species bonded with three different adhesives. Mathematical models are developed to expand the use of the data beyond the specific conditions for which it is measured.

Ventilation problems raised with the beginning of underground mining. In underground mining, to provide safe and healthy working conditions, ventilation should be designed properly. Especially in the planning stage of the project, to design ventilation properly is very important. The latest upgrade of the popular ventilation simulation program, known as VnetPC 2000, has been applied for the ventilation design. In this study simulation is conducted to both auxiliary and main ventilation at Ç
ayirhan G Field. Information describing the geometry of a ventilation network, airway characteristics and locations, characteristics of different fans were prepared as an input. The output includes predicted airflows, frictional pressure drops, air power, losses in airway and fan operating points for different trials. After different trials it has been found that for auxiliary ventilation, where minimum required amount of air is 6 m3/s, ENGART, 30A 40SCV/60HR model fan which is the most economical one was selected. For main ventilation system, 5 fans which provide airflow more than minimum requirement were chosen. Among them the most economical one, that is ALPHAIR-5400VAX2100 HB, was selected for the mine.

An efficient route for the synthesis of a new highly selective and easily displaced chiral auxiliary I for the asymmetric boron-mediated aldol reaction has been developed in 5 steps from norephedrine. The novel chiral auxiliary has been shown to mediate anti and syn propionate and glycolate aldol reactions with a range of aldehydes in excellent yield (60-98%) and with good to excellent diastereoselectivity. Details of the methods which have been used to assign the absolute and relative stereochemistry of the aldol adducts are also summarised. The facile displacement of auxiliary I with a range of nucleophiles under very mild conditions to give the corresponding phosphonate esters, alcohols, acids, SNAc thiolesters and methyl esters has been demonstrated.

O presente trabalho consiste na investigação das características da imagem mamográfica digitalizada para definir automaticamente parâmetros de processamento em um esquema de diagnóstico auxiliado por computador (CAD) para mamografia, com o objetivo de se obter o melhor desempenho possível. Além disso, com base na aplicação dos resultados dessa primeira investigação, propõe-se também uma técnica de redução dos índices de falso-positivo em esquemas CAD visando à redução do número de biópsias desnecessárias. Para a definição automática dos parâmetros de processamento nas técnicas de detecção de microcalcificações e nódulos, foram extraídas algumas características das imagens, como desvio padrão, terceiro momento e o limiar de binarização. Utilizando o método de automatização proposto, observou-se um aumento de 20% no desempenho do esquema CAD (Az da curva ROC) em relação ao método não automatizado com parâmetro fixo. Para que fosse possível o processamento da imagem mamográfica inteira pelo esquema CAD e as técnicas desenvolvidas, foi desenvolvida também uma técnica para seleção automática de regiões de interesses, que recorta partes relevantes da mama para a segmentação. O índice de falsos positivos foi tratado por técnica específica desenvolvida com base na comparação das duas incidências típicas do exame mamográfico que, juntamente com a avaliação automática da imagem no pré-processamento para detecção de microcalcificações produziu uma redução significativa de 86% daquela taxa em relação ao procedimento de parâmetro fixo.
This present work consists on the investigation of mammographic image characteristics for automatic determination of image processing parameters for a mammography computer aided diagnosis scheme (CAD) in order to get optimal performance. Additionally, using the results obtained on this first investigation, it was also developed a new technique for the reduction of false-positive rates on CAD projects, which can result on the reduction of the number of unnecessary biopsies. For the automatic definition of the image processing parameters for the techniques of detection of microcalcifications and nodules, some image characteristics had been extracted, as standard deviation, third momentum and the thresholding value. Using the proposed automatization method it was reported an increase of 20% in the CAD performance (evaluated determining the ROC curve) in comparison to the non-automatic method (fixed parameter). Besides, for CAD schemes it is necessary to process the entire mammographic image. Thus, it was also developed a technique for automatic selection of regions of interests in the mammogram, which extracts better regions from breast image for further segmentation. False-positives rates was treated by a specific technique based on the comparison of the two typical incidences of mammographic examination that together with the automatic parameter determination method for microcalcification detection produced a significant reduction of 86% of that rate in relation to the procedure that uses fixed parameter.

Metallo-supramolecular hydrogels have interesting dynamic properties for many applications. We report a simple method for synthesizing copper-based polymer hydrogels made from nontoxic poly(methyl vinyl ether-alt-maleic anhydride) (PVM-alt-MA) in the absence or presence of added dicarboxylates, such as adipate and terephthalate. We utilize metal-polycarboxylate backbone and carboxylate spacer ligands between polymers strands engineered via non-covalent metal ion coordination. Rheological measurements revealed that the mechanical stability of the hydrogels was enhanced by the addition of supplementary dicarboxylate ligands. The optimal ratio of polymer to dicarboxylate to Cu2+ was 10:4:2.5. Our scanning electron microscope (SEM) and Cryo-SEM imaging and physical adsorption measurements revealed the formation of pores. The Brunauer–Emmett–Teller (BET) surface area of the dried hydrogels increased from 177.96 m2 g−1 in a dried hydrogel without added dicarboxylate to 646.90 and 536.44 m2 g−1 with the addition of adipate and terephthalate, respectively. The pore volume increased as well. Separation of CO2 from post-combustion flue gases is important for environmental and economic sustainability. The PVM-alt-Na-MA:adipate:Cu2+ hydrogels are promising material for post-combustion CO2 separation. At normal conditions (298 K and 1 bar), the PVM-alt-Na-MA:adipate:Cu2+ hydrogel samples with 10:4:2.5 ratio, showed notable CO2/N2 selectivity of 78.46 and a high CO2/CH4 selectivity reaching 26.09 at 1 bar. Additionally, we investigated in detail the effect of transition metal ion on the rigidity and structure of hydrogels using Al3+, Fe3+, Cu2+, Ni2+, Zn2+, and Co2+. We also studied the effect of using tricarboxylate spacer ligands such as nitrilotriacetic (NTA) and trisodium citrate or tetracarboxylate such as ethylenediaminetetraacetic acid (EDTA). It is important to mention that one of the main advantages of our facile synthesis method is being simple and can be scaled up for commercial applications. For scaling up the synthesis of hydrogels, we utilized a filling machine that is able to increase the amount of hydrogel aliquots with variable volume. Silver-based hydrogels showed significant antibacterial activity, due to the presence of silver nanoparticles. We utilized a filling machine for application of amorphous wound dressing. The optimization of the conditions of the filling enabled us to scale up the synthesis and the filling process.
