Повний текст джерелаEl objectiu principal d'aquesta tesi és donar un pas endavant en el coneixement dels processos geològics que intervenen en la formació de les conques sedimentàries mitjançant la creació d'un model numèric per modelitzar la sedimentació sintectònica en un ambient subaquàtic. El model numèric desenvolupat en aquesta tesi és capaç de modelitzar la sedimentació clàstica subaquàtica i la deformació de la unitat pretectònica en una sola configuració. Per fer això, el model combina dos models ja existents: un model d'elements discrets per simular la deformació de la unitat pretectònica (DEM) i un model sedimentari basat en processos, per modelitzar la sedimentació clàstica subaquàtica Simsafadim (SFM). La unió d'aquest dos models, DEM i SFM, proporciona una nova eina per a la modelització geològica. En el nou model, l’evolució de deformació en la unitat pretectònica canviarà la topografia de la conca, que afectarà directament la batimetria, influenciant així els processos de transport i sedimentació que hi tenen lloc. Alhora, aquesta evolució de la deformació de la unitat pretectònica estarà influenciada per la presència dels nous materials sintectònics. Amb aquesta doble interacció tectònica-sedimentària del nou model, també es pot estudiar la deformació en els materials sintectònics. Aquesta nova eina de modelització permet simular i analitzar diferents arquitectures deposicionals sintectòniques i escenaris geològics més complexos. Tant per ampliar el coneixement de com els processos de sedimentació-deformació interactuen en alguns ambients tectònics, com per comprovar l'eficàcia del model, la nova eina s'aplica a dos casos diferents: 1) En primer lloc s'utilitza el model numèric en un ambient extensional per estudiar l'impacte que té la presència de falles normals i les corresponents zones de relleu en la distribució del sediment a la conca. Quan es compara la distribució de sediment obtinguda amb una configuració de dos falles amb una rapa de relleu, amb la distribució de sediment obtinguda amb una configuració d'una sola falla, els resultats mostren asimetries, tant longitudinals com perpendiculars a les estructures. 2) En el segon cas s'estudia l'efecte de la sedimentació sintectònica sobre la geometria final d'un plec. Els resultats, obtinguts a partir de la comparació de l'evolució de les estructures considerant o no considerant sedimentació sintectònica, estableixen que la sedimentació sintectònica pot afectar tant al mecanisme de formació del plec com a la seva geometria final.

Повний текст джерелаThe competitive marketplace systematically demands reduced costs and more flexibility from contemporary organizations which, in turn, can achieve better results by focusing on the development of their supply chains. Thus, supply chain maturity models present themselves as allies in the leverage process of organizations. Despite the increasing number of models in this field of knowledge, the literature points to a gap in the creation of hybrid, adaptive models that are predisposed to measure the supply chain in a broad way. From this gap, the objective of this dissertation was to develop a maturity model in supply chain management with an associated measurement tool. For this, a methodology was developed subdivided in three phases, covering: the introductory studies, the bibliographical research and the effective development of the model and tool. The result of this research was the creation of the technological product, with registration in the National Institute of Industrial Property (INPI), Supply Chain Management Maturity Model (SCM3). SCM3 is interdisciplinary, multidimensional and composed of 6 application dimensions: supplier management, operation and customer management, logistic activities management, human resources, technological systems and performance measurement system. The SCM3 uses the concept of turning points to change maturity level, which confers greater pragmatism to the model. The operationalization of this model also required the development of a method to support organizations for the implementation. The computational tool prototype associated to SCM3 generates compatible and comparable results, gathering 153 questions and 5 functionalities. The validation stage of the model was attended by specialists from both the market and academy, who evaluated aspects inherent to the interface, content, logical linkage, viability and acceptability of the model. The model was applied in an organizational environment in two large companies, leaders of the Brazilian telecommunications sector, counting with the participation of the managerial layer of the companies. The application has proved to be relevant for organizations and academics, being able to perform numerous analyzes for organizations to leverage their chains and support future benchmarking studies in supply chain maturity.

Este trabalho apresenta uma ferramenta baseada em modelos para derivação de produtos de LPSs, denominada GenArch. O objetivo principal da ferramenta é permitir que a comunidade de desenvolvimento de software tradicional, utilize conceitos e fundamentos de abordagens de LPSs na produção de seus sistemas ou partes de seus sistemas sem a necessidade do entendimento de modelos e conceitos complexos. A abordagem implementada pela ferramenta foi elaborada com base em fundamentos do desenvolvimento dirigido por modelos. Centrada na definição de três modelos (características, implementação e configuração), a ferramenta permite a derivação automática de produtos ou frameworks existentes. O trabalho também define um conjunto específico de anotações Java que possibilitam a geração automática dos modelos de derivação a partir dos elementos de implementação da arquitetura de uma LPS. A plataforma Eclipse e as tecnologia EMF e openArchitectureWare foram utilizadas como base para a implementação da ferramenta. Uma extensão da ferramenta que atende especificamente aos modelos de componente Spring e OSGi, também é proposta nessa dissertação. Tal extensão permite a instanciação automática da LPS e aplicações através de diferentes tipos de customizações, variando da configuração fina de propriedades de componentes até a seleção automática de quais componentes irão compor o produto final. Como parte de validação da abordagem, a ferramenta foi utilizada na derivação automática de três diferentes estudos de caso: (i) o framework JUnit; (ii) uma LPS de jogos J2ME; e (iii) uma aplicação web baseada em serviços. Diversas lições aprendidas e resultados do uso da ferramenta nestes três diferentes cenários são também apresentadas.
This work presents a model-based tool for product derivation, called GenArch, which aims to enable the mainstream software developer community to use the concepts and foundations of the SPL approach, without the need to understand complex concepts or models. The tool approach is build on top of model-driven development techniques. It is centered on the definition of three models (feature, implementation and configuration models), which enable the automatic instantiation of software product lines (SPLs) or frameworks. A set of specific Java annotations are also defined to allow generating automatically many of the models, based on existing implementations elements of SPL architectures. The Eclipse platform, and EMF and openArchitectureWare technologies are used as the base for the implementation of the tool. The dissertation also presents a GenArch extension that addresses the new abstractions provided by the Spring and OSGi component models. Different kinds of customizations are provided by this extension varying from fine-grained configuration of component properties to the automatic selection of components that will compose the final product. As part of the approach validation, the tool was used in the derivation of three case studies: (i) JUnit framework; (ii) a J2ME games SPL; (iii) a service oriented Web application. Several lessons learned and discussions resulting from the use of the tool also are described.

Повний текст джерелаBackground: Computational simulation of complex biological networks lies at the heart of systems biology since it can confirm the conclusions drawn by experimental studies of biological networks and guide researchers to produce fresh hypotheses for further experimental validation. Since this iterative process helps in development of more realistic system models a variety of computational tools have been developed. In the absence of a common format for representation of models these tools were developed in different formats. As a result these tools became unable to exchange models amongst them, leading to development of SBML, a standard exchange format for computational models of biochemical networks. Here the formats of SBML and one of the commercial tools of systems biology are being compared to study the issues which may arise during conversion between their respective formats. A tool StoP has been developed to convert the format of SBML to the format of the selected tool.
Results: The basic format of SBML representation which is in the form of listings of various elements of a biochemical reaction system differs from the representation of the selected tool which is location oriented. In spite of this difference the various components of biochemical pathways including multiple compartments, global parameters, reactants, products, modifiers, reactions, kinetic formulas and reaction parameters could be converted from the SBML representation to the representation of the selected tool. The MathML representation of the kinetic formula in an SBML model can be converted to the string format of the selected tool. Some features of the SBML are not present in the selected tool. Similarly, the ability of the selected tool to declare parameters for locations, which are global to those locations and their children, is not present in the SBML.
Conclusions: Differences in representations of pathway models may include differences in terminologies, basic architecture, differences in capabilities of software’s, and adoption of different standards for similar things. But the overall similarity of domain of pathway models enables us to interconvert these representations. The selected tool should develop support for unit definitions, events and rules. Development of facility for parameter declaration at compartment level by SBML and facility for function declaration by the selected tool is recommended.

Повний текст джерелаThe development of advanced embedded systems requires a systematic approach as well as advanced tool support in dealing with their increasing complexity. This complexity is due to the increasing functionality that is implemented in embedded systems and stringent (and conflicting) requirements placed upon such systems from various stakeholders. The corresponding system development involves several specialists employing different modeling languages and tools. Integrating their work and the results thereof then becomes a challenge. In order to facilitate system architecting and design integration of different models, an approach that provides dedicated workspaces/views supported by structured information management and information exchange between domain models and tools is required.
This work is delimited to the context of embedded systems design and taking a model based approach. The goal of the work is to study possible technical solutions for integrating different models and tools, and to develop knowledge, support methods and a prototype tool platform.
To this end, this thesis examines a number of approaches that focus on the integration of multiple models and tools. Selected approaches are compared and characterized, and the basic mechanisms for integration are identified. Several scenarios are identified and further investigated in case studies. Two case studies have been performed with model transformations as focus. In the first one, integration of Matlab/Simulink® and UML2 are discussed with respect to the motivations, technical possibilities, and challenges. A preliminary mapping strategy, connecting a subset of concepts and constructs of Matlab/Simulink® and UML2, is presented together with a prototype implementation in the Eclipse environment. The second case study aims to enable safety analysis based on system design models in a UML description. A safety analysis tool, HiP-HOPS (Hierarchically Performed Hazard Origin and Propagation Studies), is partially integrated with a UML tool where an EAST-ADL2 based architecture model is developed. The experience and lessons learned from the experiments are reported in this thesis.
Multiple specific views are involved in the development of embedded systems. This thesis has studied the integration between system architecture design, function development and safety analysis through using UML tools, Matlab/Simulink, and HiP-HOPS. The results indicate that model transformations provide a feasible and promising solution for integrating multiple models and tools. The contributions are believed to be valid for a large class of advanced embedded systems. However, the developed transformations so far are not really scalable. A systematic approach for efficient development of model transformations is desired to standardize the design process and reuse developed transformations. To this end, future studies will be carried out to develop guidelines for model and tool integration and to provide support for structured information at both meta level and instance level.

Повний текст джерелаUna malla es una discretización de la geometría de un cierto dominio. Las mallas pueden estar compuestas de diversos elementos: triángulos, cuadriláteros, tetraedros, etc. Una herramienta para la generación de mallas es un aplicación que permite crear, refinar, desrefinar, mejorar, suavizar, visualizar y posprocesar mallas y/o una región particular de ella, como también asignar valores físicos a los elementos de la malla (temperatura, concentración, etc.). Las herramientas para la generación de mallas son complejas y sofisticadas, y construir una herramienta nueva desde cero o mantener una existente, demanda un esfuerzo enorme. Existe una necesidad y oportunidad para usar enfoques nuevos en el desarrollo de estas herramientas, de manera de reducir tanto el tiempo como los costos de desarrollo, sin comprometer la calidad. La experiencia en el desarrollo de estas herramientas provee la motivación para la construcción de otras nuevas mediante la reutilización del trabajo realizado durante los desarrollos previos. Estas herramientas comparten varias características y sus variaciones pueden ser manejadas sistemáticamente. Esto hace que el desarrollo de estas herramientas sea una buena oportunidad para aplicar el enfoque de Línea de Productos de Software (LPS). Los procesos existentes de LPS son generales y requieren usualmente una serie de pasos y documentación innecesaria en el dominio de las herramientas para la generación de mallas. Así, esta tesis propone un modelo de proceso de LPS específico para este tipo de herramientas. Un proceso de desarrollo de LPS está centrado en la reutilización de software, e involucra principalmente dos fases: la ingeniería del dominio (ID) y la ingeniería de la aplicación (IA). El proceso presentado en este trabajo está centrado en dos etapas de la ID: el análisis del dominio (AD) y el diseño del dominio (DD). En el AD se define el modelo del dominio y el alcance de la LPS. En el DD la arquitectura de la línea de productos (ALP) es creada; esta arquitectura es válida y compartida por todos los productos en la LPS. Un modelo de características es comúnmente usado para modelar el dominio. En este trabajo, el AD también ocupa un diccionario, escenarios, acciones y metas para proveer el razonamiento utilizado para la construcción del modelo de características. Esta tesis presenta un proceso riguroso para obtener el modelo del dominio. Este modelo es formalizado mediante condiciones de consistencia y completitud. El proceso de definición del alcance es presentado a través de un diagrama de actividad. Además, el enfoque presentado en esta tesis presenta explícitamente los diferentes productos de la LPS, estableciendo relaciones entre productos y las características de la LPS, lo que permite administrar el desarrollo del producto. La etapa de DD se centra en la creación de la ALP, artefacto esencial para la construcción de productos de la LPS. Para ello, este trabajo provee un proceso deductivo y otro transformacional. En el primero, una ALP explícita es desarrollada, usando los artefactos producidos en el AD. Además, tanto la vista arquitectónica estructural como la de comportamiento son establecidas. Ambas vistas son generales y permiten la representación de cualquier producto dentro del alcance de la LPS. En el proceso transformacional, una ALP implícita es desarrollada usando reglas de transformación, las que han sido creadas usando artefactos producidos en el AD. En este proceso se produce la arquitectura para productos específicos, y la ALP es definida como la suma de todas las arquitecturas de los productos. Tanto el AD como el DD son descritos en detalle, y la aplicación del modelo de la LPS es ilustrado a través de un ejemplo bien documentado en el dominio de las herramientas para la generación de mallas, el que tiene un grado relativamente alto de complejidad. En este ejemplo, un modelo del dominio formalizado es introducido, y la arquitectura es definida tanto para el proceso deductivo como para el transformacional.

Повний текст джерелаIn the light of instructional psychology the outcome of computer based learning aids can be described as a chain of causation consisting of constructivist forms of knowledge acquisition (Edelmann, 1996), generative processes (Wittrock, 1990) and digital mind tools (Jonassen, 1992). Aim of the present work is to proof this causal assumption empirically. Therefore, a computer based learning and testing environment was set up. It based on 3 single digital mind tools, which are supposed to help learning the construction, functionality and handling of a simple deterministic plant for soap production. Additionally, paper & pencil were provided. The measured variables cover the learning process (e.g. time, inputs) and the learning outcome (multiple-choice test, operating test). In a first series of 4 laboratory experiments 109 students were given no or one of the digital mind tools. In result, all 3 means initiate new generative processes. But the mental models of their users are not more sophisticated in whole. There was improvement in special areas, depending on characteristics of the tools (interaction modes, representable content, and visualisation). The findings were statistically compared to older data of a parallel test series (Wipper, 2004) but only marginal differences occurred. In a further laboratory experiment 98 students were given a combination of the 3 digital mind tools mentioned above. This hybrid learning environment initiates new generative processes as well. Because of an additional combination of the focussing effects caused by the tools, the mental model of its users is comprehensively more sophisticated now. Moreover, those people reach constantly much higher scores in all measures than the other subjects. The findings confirm the causal chain mentioned at the beginning.

Повний текст джерелаIn the recent years, the agricultural activity of the citrus industry has been facing big phytosanitary problems, mainly with regard to economic viability arising from disease control. The bacterium Candidatus Liberibacter spp. is associated with HLB, the main disease that limits the production of citrus trees. Thus, many researchers have been returning their attentions to study and find target genes in the host response to this pathogen for use in the genetic improvement. In this way, methods of genetic transformation of citrus plants are essential, but the inherent characteristics of the species border your in vitro cultivation and require a longer time for growth and propagation. Therefore, it is important to study of model plants, mainly for genetic validation protocols. Thus, the EDS5 gene isolated from Citrus sinensis, associated with Systemic Acquired Resistance mechanism (SAR) was overexpressed by genetic transformation in tomato (Solanum lycopersicum L. Micro-Tom). After the growth of regenerated shoots, positive plants were identified by PCR and GUS analysis. Homozygous transgenic lines were obtained with evaluation of resistance to kanamycin.

Повний текст джерелаAlthough the citrus industry is an important economic activity in Brazil, in recent years there has been a significant reduction in the national citrus production. The low profitability of the citrus sector has faced due to the high production cost is mainly attributed to phytosanitary problems, particularly diseases that directly affect productivity of orchards. Currently, huanglongbing (HLB) is the most serious disease that affects the global citrus industry and the damage is severe in all citrus varieties. Genetic transformation of plants is an alternative to obtain transgenic plants with genes that stimulate the plant defense system, making it resistant to diseases. Despite the effectiveness of protocols for genetic transformation of citrus, a characteristic disadvantage of perennial plants is the slow reproductive cycle, hindering validation of new genes of interest. Therefore, an important strategy is the use of model plants, such as the tomato, which has a short cycle and good genetic transformation efficiency. The objective of this study was to obtain transgenic plants of Solanum lycopersicum cv. \"Micro-Tom \'and Citrus sinensis, containing the gene construct with Csd1 gene (copper/zinc superoxide dismutase), isolated of Poncirus trifoliata. The protein encoded by the gene Csd1, also known as SOD1 (superoxide dismutase 1), is the most powerful antioxidant in nature and is important constituent of cellular defense against oxidative stress caused by bacterial infection. \'Micro-tom\' tomato was used as a model for pathogenic gene validation. However, due to its low efficiency of genetic transformation, the inoculation experiments with the pathogen were not realized. Posteriorly, the characterization of gene function Csd1 in relation to the HLB disease will be realize with citrus transgenic plants. The objective of this study was to obtain transgenic plants of Solanum lycopersicum cv. \'Micro-Tom\' and of Citrus sinensis, containing the gene construction with Csd1 gene (copper/zinc superoxide dismutase), isolated of Poncirus trifoliata, for validation and for future study of this gene for resistance to HLB. Proteins encoded by the Csd1 gene, also known as SOD1 (superoxide dismutase 1), are the most powerful antioxidants in nature and are important constituents of cellular defense against oxidative stress caused by bacterial infection. The identification of transgenic plants of tomato and sweet orange was performed by the PCR analysis using primers for the detection of Csd1 gene. The PCR+ plants were acclimatized and transferred to a greenhouse. The genetic transformation efficiency of tomato \'Micro-Tom\' and sweet orange cultivars, \'Hamlin\' and \'Pineapple\', were 0.34%, 4.74% and 3.65%, respectively. The molecular characterization with the Southern blot and RT-qPCR analyses was performed only in citrus plants. The transgene integration was confirmed in 32 plants. The number of insertion events ranged from 1-5 and the presence of Csd1 endogenous gene is found in three distinct locations in the plants genome. The mRNA level of the transgene was verified in 21 plants that had only a single transgene insertion into the plant genome. The results show that there was transcription of Csd1 gene in transgenic plants as well as in non-transgenic plants. The relation between the transgene transcript level with the resistance of plants to pathogens is set after inoculation with Candidadus Liberibacter.

Free-form surface machining is a fundamental but time-consuming process in modern manufacturing. The central question we ask in this thesis is how to reduce the time that it takes for a 5-axis CNC (Computer Numerical Control) milling machine to sweep an entire free-form surface in its finishing stage. We formulate a non-classical variational time-optimization problem defined on a 2-dimensional manifold subject to both equality and inequality constraints. The machining time is the cost functional in this optimization problem. We seek for a preferable vector field on a surface to obtain skeletal information on the toolpaths. This framework is more amenable to the techniques of continuum mechanics and differential geometry rather than to path generation and conventional CAD/CAM (Computer Aided Design and Manufacturing) theory. After the formulation, this thesis derives the necessary conditions for optimality. We decompose the problem into a series of optimization problems defined on 1-dimensional streamlines of the vector field and, as a result, simplify the problem significantly. The anisotropy in kinematic performance has a practical importance in high-speed machining. The greedy scheme, which this thesis implements for a parallel hexapod machine tool, uses the anisotropy for finding a preferable vector field.
(cont.) Numerical integration places tool paths along its integral curves. The gaps between two neighboring toolpaths are controlled so that the surface can be machined within a specified tolerance. A conservation law together with the characteristic theory for partial differential equations comes into play in finding appropriately-spaced toolpaths, avoiding unnecessarily-overlapping areas. Since the greedy scheme is based on a local approximation and does not search for the global optimum, it is necessary to judge how well the greedy paths perform. We develop an approximation theory and use it to economically evaluate the performance advantage of the greedy paths over other standard schemes. In this thesis, we achieved the following two objectives: laying down the theoretical basis for surface machining and finding a practical solution for the machining problem. Future work will address solving the optimization problem in a stricter sense.

Повний текст джерелаFör detta projekt används ett simuleringsverktyg Software-In-the-Loop (SIL) på Scania (“VTAB” - Virtual Truck and Bus), vilket simulerar submodellerna för de mekaniska fordonskomponenterna tillsammans med de verkliga styrenheterna. Simuleringsverktyget innehåller följande submodeller: Motormodell, Drivmotormodell, Drivcykelmodell, Restbusmodell och Drivermodell. Den simulerade submodellen för mänsklig förare i restbussmodellen kommer att sända två pedalsstyrsignaler till styrenheten, nämligen gas och broms. Med dessa två pedalsignaler kan styrenheten avgöra lägen av mekaniska fordonskomponenter. Denna drivrutinmodell måste omarbetas för att få en bättre hastighetsspårnings presentationsförmåga. Två styrenheter, fuzzy PI anti-windup och bakåtberäkning, implementeras i förarmodell och jämförs respektive med hastighetsspårningsnoggrannhet och pedalväxelfrekvens. I jämförelseoch analysavsnittet simuleras två olika cyklar och två nyttolast. Simuleringsresultaten visar att båda kontrollerna kan förbättra förarmodellens hastighetsspårningskapacitet. Vidare är fuzzy PI-anti-windup-kontroller bättre när man tar hänsyn till pedalsignalernas fluktueringsfrekvens och implementeringskomplexitet

Повний текст джерелаIt was made in this work an investigative comparison of the behavior of the tool steels H13 and THYROTHERM 2999 EFS SUPRA, designed for die steels for hot forming, when exposed to high temperature low cycle fatigue (HTLCF). From their tempering curves three material working hardness were defined for each material (hardness of 42, 52 and 58 HRC), corresponding to three different tempering temperatures, and so three study cases for each material, searching for the best condition for this kind of application, and to assess the influence of the initial hardness on the part material life. The isothermal low cycle fatigue test temperature was either defined at 400°C, corresponding to the used temperature at the die steel, i.e., a critical typical temperature that the forging dies reach on hot working. After that, tensile tests were performed for both materials, at room temperature, and at the working temperature formerly defined, and these tests allowed the definition of the first monotonic parameters for these materials, among them predictions for strain levels (0.5, 0.6, 0.7, 0.8, 0.9, 1.0 and 1.1%), to be used on fatigue tests, and further parameters like E, k, n, σe, σ’f, ε’f, b, c, that allowed the elaboration of ε−N curves, based on a still existing prediction model. Finally, isothermal low cycle fatigue tests were performed, at 400°C, and the results were used for ε−N curves elaboration, resulting on a prediction model of the fatigue strength specified for the assessed materials.

Повний текст джерелаSom forskare fann att genom hela historien är en gemensam utmaning för företag inom olika branscher när det gäller att utnyttja och fånga värde från en teknologisk innovation starkt påverkad av företagets dominerande affärsmodell, en etablerad ram genom vilken bedömning sker. Det övergripande syftet med denna studie är att ge en djupare förståelse för den roll som företagets dominerande affärsmodell har vid bedömningen av den inverkan som ny teknik innovation, i detta fall AI, kommer att ha på företaget och marknaden där företaget driver . Denna avhandling är delvis undersökande och delvis beskrivande med kvalitativ och deduktiv natur. För att svara på målet användes en forskningsstrategi av fallstudier där empiriska data samlades in från intervjuer med 47 bolagets ledande befattningshavare från olika hierarkiska nivåer och affärsenheter, från Sverige, Schweiz, USA, Tyskland och Finland. Den teoretiska ram som beskriver hur AI som ett nytt teknikverktyg uppfattas ur företagets Xperspektiv, antingen som en radikal, spelväxlare eller ett inkrementellt innovationsteknologiprogram och undersöker den roll som dominerande affärsmodell har på denna uppfattning skapades. Den utvecklade implementeringsramen har grundat sig i tidigare forskning rörande innovationsmodellteorier. Data som samlades in från företagets chefer analyserades sedan och jämfördes med modellen. De viktigaste resultaten tyder på att AI som ett nytt teknikverktyg uppfattas som en spelväxlare, radikalt innovationsverktyg för vissa områden inom företaget X och att företagets dominerande affärsmodell påverkar denna uppfattning väsentligt.

Повний текст джерелаProcess calculi are simple languages which permit modeling of concurrent systems so that they can be verified for correctness. We can analyze concurrent systems based on process calculi by either comparing a representation of the actual implementation with a simpler specification for equivalence, or by verifying whether desired properties described in an adequate logic hold. Strong bisimulation equivalence is one of many equivalence relations defined on process calculi to aid in the verification of concurrent software. This equivalence relation relates processes which exhibit the same behavior, i.e. perform the same transitions, as equivalent regardless of internal implementation details. Logics to reason about processes range from those which describe temporal properties – how properties evolve during the course of a process’ life – behavioral properties – which actions a process is capable of performing – and spatial properties – what components compose a process and how are they connected. Model checking consists of verifying if a model, in our case a process, satisfies a given property. Model checking techniques are quite popular in conjunction with process calculi to aid in the verification of the correctness of concurrent systems. In this thesis we address the problems of checking bisimilarity between processess using characteristic formulae, which are formulae used to fully describe a process’ behavior. We implement some facilities to allow bisimilarity verification in the Spatial Logic Model Checker tool. As a result of adding these facilities we also extend the SLMC tool with an extra modality in the logic it uses to reason about processes. We have also added the possibility to define mutually recursive properties in the tool and enhanced the model checking algorithm with a cache to prevent redundant, time-consuming checks to be performed.

Повний текст джерелаDue to the process of city growth and agricultural activity there are impacts that affect water resources such as scarcity, degradation of water quality and consequent conflicts of uses. In this context, hydrological models are important tools to evaluate the hydrological behavior of watersheds, and can also be used to predict scenarios to verify the impact of land use and occupation. Thus, the present study had as purpose to evaluate the performance of the Soil and Water Assessment Tool (SWAT) model in the flow simulation in the Ribeirão Taquaruçu Watershed. The automatic calibration was performed with the SWAT-CUP program, in a daily step, with data from two BRK Ambiental fluviometric stations from April 2013 to July 2014, while data from August 2014 to August 2015 were used in the period of validation. The sensitivity analysis was performed with 14 parameters chosen considering the most significant ones for the simulation of flow in the Cerrado region. The results of the sensitivity analysis indicated that the most influential parameters are the SOL_K (saturated hydraulic conductivity of the soil) and CN2 (number curve for condition II). The Nash-Sutcliffe objective functions (NSE) and the determination coefficient (R2) were used to evaluate the performance of the model, which indicated, in the calibration period, the following values: - 0.05 and 0.55 (sub-basin 1); 0.51 (sub-basin 3), respectively. In the validation period, the following results were presented for NSE and R2: 0,44 and 0,54 (sub-basin 1); 0.24 and 0.29 (sub-basin 3), in that order. Considering that the object of study is important because it is responsible for a large part of the water supply of the municipality of Palmas – TO and that the software was not able to simulate the minimum flows adequately, the results are considered unsatisfactory.
