This dissertation reviews this regional promotional policy through several perspectives with the purpose of shedding some light onto performed stages and the mechanisms applied in its evolution, pitching it against the legal security, an indispensable element for a Law-abiding Democratic State. The study starts off from a rereading of the theories underpinning the conceptual evolution of development both from the interdisciplinary standpoint of the economy, the history and of the economic law giving priority to those which directly or indirectly have influenced the conceptual basis of the Manaus Industrial Hub and showing the new dimensions, highlighting the issue of socioenvironmental sustainability, intrinsically applicable to the Amazon reality. As a whole, the main phases of the national development as sequenced starting from the thirties of the XX century the when the Brazilian State began to adopt developmental strategies until these days, emphasizing political and economic aspects, which have interfered in the readequability of the original proposal and have produced its current conformation, with a brief historical description the public policies, which have intended to interfere in the economic and industrial performance of the Amazon space resulting in the creation of the Manaus Free Trade Zone (ZFM) and of the Manaus Industrial Hub (PIM). The text puts forward some reflections on its main phases, contradictions, difficulties and perspectives and the repercussions resulting from the regulatory alterations at all levels, to, at the end, promote a study of the main constitutional and tributary focuses of the issue giving priority to the theme of legal security, probing into its real existence and effectiveness. / O estudo do modelo de desenvolvimento do Polo Industrial de Manaus reveste-se de importância pela sua representatividade para o Estado do Amazonas e repercussão no contexto da região Amazônica. A presente dissertação analisa essa política de promoção regional sob várias vertentes com a finalidade de compreender os estágios empreendidos e os mecanismos aplicados na sua evolução, confrontando-os com a segurança jurídica, elemento indispensável no Estado Democrático de Direito. O estudo parte da releitura de teorias que embasaram a evolução conceitual do desenvolvimento, tanto pela ótica interdisciplinar da economia, da história e do direito econômico, priorizando aquelas que direta ou indiretamente influenciaram a base conceitual do Polo Industrial de Manaus e apresentando as novas dimensões, com destaque para a questão da sustentabilidade socioambiental, intrinsecamente aplicável à realidade amazônica. No conjunto, são seqüenciadas as principais fases do desenvolvimento nacional, partindo dos anos trinta do século XX quando o Estado brasileiro passou a adotar estratégias desenvolvimentistas até os dias atuais, ressaltando aspectos políticos e econômicos que interferiram na readequação da proposta original e produziram a sua atual conformação, com breve relato histórico as políticas públicas que se propuseram a interferir no desenvolvimento econômico e industrial do espaço amazônico resultando na criação da Zona Franca de Manaus (ZFM) e do Polo Industrial de Manaus (PIM). O texto traz reflexões sobre suas principais fases, contradições, entraves e perspectivas e as repercussões decorrentes das alterações normativas em todos os níveis, para ao final promover um estudo dos principais enfoques constitucionais e tributários da questão, com prioridade para o tema da segurança jurídica, perquirindo sobre a sua real existência e eficácia.

In this thesis, we introduce the Partitioning-Hub Location-Routing problem (PHLRP), which can be classified as a variant of the hub location problem.<p>PHLRP consists of partitioning a network into sub-networks, locating at least one hub in each subnetwork and routing the traffic within the network such that all inter-subnetwork traffic is routed through the hubs and all intra-subnetwork traffic stays within the sub-networks all the way from the source to the destination. Obviously, besides the hub location component, PHLRP also involves a graph partitioning component and a routing component. PHLRP finds applications in the strategic planning or deployment of the Intermediate System-Intermediate System (ISIS) Internet Protocol networks and the Less-than-truck load freight distribution systems.<p><p>First, we introduce three IP formulations for solving PHLRP. The hub location component and the graph partitioning components of PHLRP are<p>modeled in the same way in all three formulations. More precisely, the hub location component is represented by the p-median variables and constraints; and the graph partitioning component is represented by the size-constrained graph partitioning variables and constraints. The formulations differ from each other in the way the peculiar routing requirements of PHLRP are modeled.<p><p>We then carry out analytical and empirical comparisons of the three IP<p>formulations. Our thorough analysis reveals that one of the formulations is<p>provably the tightest of the three formulations. We also show analytically that the LP relaxations of the other two formulations do not dominate each other. On the other hand, our empirical comparison in a standard branch-and-cut framework that is provided by CPLEX shows that not the tightest but the most compact of the three formulations yield the best performance in terms of solution time. <p><p>From this point on, based on the insight gained from detailed analysis of the formulations, we focus our attention on a common sub-problem of the three formulations: the so-called size-constrained graph partitioning problem. We carry out a detailed polyhedral analysis of this problem. The main benefit from this polyhedral analysis is that the facets we identify for the size-constrained graph partitioning problem constitute strong valid inequalities for PHLRP.<p><p>And finally, we wrap up our efforts for solving PHLRP. Namely, we present<p>the results of our computational experiments, in which we employ some facets<p>of the size-constrained graph partitioning polytope in a branch-and-cut algorithm for solving PHLRP. Our experiments show that our approach brings<p>significant improvements to the solution time of PHLRP when compared with<p>the default branch-and-cut solver of XPress. <p><p>/<p><p>Dans cette thèse, nous introduisons le problème Partitionnement-Location des Hubs et Acheminement (PLHA), une variante du problème de location de hubs. Le problème PLHA partitionne un réseau afin d'obtenir des sous-réseaux, localise au moins un hub dans chaque sous-réseau et achemine le traffic dans le réseau de la maniére suivante :le traffic entre deux<p>sous-réseaux distincts doit être éxpedié au travers des hubs tandis que le traffic entre deux noeuds d'un même sous-réseau ne doit pas sortir de celui-ci. PLHA possède des applications dans le planning stratégique, ou déploiement, d'un certain protocole de communication utilisé<p>dans l'Internet, Intermediate System - Intermediate System, ainsi que dans la distribution des frets.<p><p>Premièrement, nous préesentons trois formulations linéaires en variables entières pour résoudre PLHA. Le partitionnement du graphe et la localisation des hubs sont modélisées de la même maniére dans les trois formulations. Ces formulations diffèrent les unes des autres dans la maniére dont l'acheminement du traffic est traité.<p><p>Deuxièmement, nous présentons des comparaisons analytiques et empiriques des trois formulations. Notre comparaison analytique démontre que l'une des formulations est plus forte que les autres. Néanmoins, la comparaison empirique des formulations, via le solveur CPLEX, montre que la formulation la plus compacte (mais pas la plus forte) obtient les meilleures performances en termes de temps de résolution du problème.<p><p>Ensuite, nous nous concentrons sur un sous-problème, à savoir, le partitionnement des graphes sous contrainte de taille. Nous étudions le polytope des solutions réalisables de ce sous-problème. Les facettes de ce polytope constituent des inégalités valides fortes pour<p>PLHA et peuvent être utilisées dans un algorithme de branch-and-cut pour résoudre PLHA.<p><p>Finalement, nous présentons les résultats d'un algorithme de branch-and-cut que nous avons développé pour résoudre PLHA. Les résultats démontrent que la performance de notre méthode est meilleure que celle de l'algorithme branch-and-cut d'Xpress.<p> / Doctorat en Sciences / info:eu-repo/semantics/nonPublished

[EN] Since its birth in the fifties, the maritime container has revolutionised freight international transport providing support to a global production system, marked by the industry offshoring looking for competitive advantages and the configuration of increasingly complex and global supply chains. Within this context, the container has gained a great importance becoming a basic logistic element in supply chains where it plays the role of a transport, production and distribution unit. The success of container is evident if we analyse the evolution of container port traffic, which has been growing at a pace of over 10 % surpassing 600 million TEU of traffic since 2012. The container is, therefore, a key element in global supply chains and container logistics is a field of work and study of enormous interest due to its impact in the efficiency of these supply chains, due to the cost incurred for the operating account of shipping companies and operators (cost which is transferred to the final user and has an impact in the price of the goods being transported), and due to the social and environmental cost associated to the externalities of transport derived from the management of the container fleet. Container logistics has to do with the efficient management of the container fleet, minimising the transport, warehousing and maintenance costs, and maximising the use of the equipment. In container logistics it is possible to categorise, generally, two different categories or levels depending on the geographical scope and the transport modes involved: The international level and the local or regional level. This thesis addresses container logistics at a local or regional level, insofar as in relation to the management of stock, transport and internal movements, trying to react and identify solutions to some of the problems currently facing the port-logistics sector. The research result allows, firstly, knowing in an integral and structured manner the complexity of maritime container logistics. Secondly, specific real problems are identified and addressed for its modelling and analysis that allows for contributing to the improvement of the current logistics system. The following specific problems are addressed: -Modal choice problems for the configuration of internal logistics corridors or chains for maritime container transport. -Problems locating networks of nodal infrastructures facilitating the logistics needs of maritime containers. -Problems related to the movements and management of empty maritime containers. The interest and the academic contribution of this thesis lies as much in the definition and modelling of the specific problems with a significant theoretical discussion, as the empirical application to a real environment and real situations. This has been possible due to the direct contact of the author with the port-logistics sector and the participation in many consultancy and research projects in the cluster of the port of Valencia and also at European and international level. The thesis is outlined as a collection of six scientific articles. The articles have been presented in the thesis in such a way as to follow a logical sequence and not in relation with the chronological order of their publication. / [ES] Desde su aparición en los años 50, el contenedor marítimo ha revoluciona-do el transporte internacional de mercancías dando soporte a un sistema global de producción, marcado por la multilocalización de las industrias en busca de ventajas competitivas y la configuración de cadenas de suministro cada vez más complejas y globales. En este contexto, el contenedor ha adquirido un gran protagonismo convirtiéndose en un elemento logístico básico en las cadenas de suministro en las que actúa como unidad de transporte, producción y distribución. El éxito del contenedor queda puesto de manifiesto al analizar la evolución del tráfico portuario de contenedores, que ha estado creciendo a ritmos superiores al 10 %, superando los 600 millones TEU desde 2012. El contenedor es, por tanto, un elemento clave de las cadenas de suministro globales y la logística del contenedor es un área de estudio y trabajo de enorme interés por el impacto que tiene en la eficiencia de dichas cadenas, por el coste que supone a navieras y operadores en sus cuentas de explotación (coste que se traslada al usuario final y repercute en el precio de las mercancías transportadas) y por el coste social y ambiental asociado a las externalidades del transporte derivadas de esta gestión de la flota de contenedores. La logística del contenedor tiene que ver con la gestión eficiente del parque de contenedores, minimizando los costes de transporte, almacenamiento y mantenimiento, y maximizando la utilización del equipo. En la logística del contenedor se pueden identificar, por lo general, dos categorías o niveles diferenciados en función del ámbito geográfico y de los modos de transporte implicados: El nivel internacional y el nivel local o regional. Este trabajo aborda la logística del contenedor a nivel regional o local, es decir, en lo relativo a la gestión del stock, transporte y movimientos interiores, tratando de dar respuesta y plantear soluciones a algunos de los problemas con los que se encuentra el sector logístico-portuario en la actualidad. El resultado de la investigación permite, en primer lugar, conocer de una forma integral y estructurada la complejidad de la logística del contenedor marítimo. En segundo lugar, se identifican y abordan problemas específicos reales para su modelización y análisis, que permiten contribuir a la mejora del sistema logístico actual. En concreto se abordan los siguientes problemas: -Problemas de elección modal en la configuración de las cadenas o corredores logísticos interiores en el transporte de contenedores marítimos. -Problemas de localización o vertebración de una red de infraestructuras nodales para atender las necesidades logísticas de los contenedores marítimos. -Problemas asociados a los movimientos en vacío y gestión de contenedores marítimos. El interés y contribución académica de este trabajo reside tanto en la definición y modelización de los problemas específicos con una profunda discusión teórica, como en la aplicación empírica a situaciones y entornos reales, cosa que ha sido posible gracias al contacto directo del autor con el sector logístico-portuario y su participación en numerosos proyectos de consulto-ría e investigación tanto en el clúster del Puerto de Valencia como a nivel europeo e internacional. El trabajo se plantea como una colección de seis artículos científicos. El orden en que están situados los artículos en la tesis permite mantener una secuencia lógica construida a posteriori y no según el orden cronológico en el que fueron publicados. / [CAT] Des del seu naixement als anys 50, el contenidor marítim ha revolucionat el transport internacional de mercaderies donant suport a un sistema global de producció, marcat per la multilocalització de les indústries en busca d'avantatges competitives i la configuració de cadenes de subministrament cada vegada més complexes i globals. En aquest context, el contenidor ha adquirit un gran protagonisme convertintse en un element logístic bàsic en les cadenes de subministrament en les quals actua com a unitat de transport, producció i distribució. L'èxit del contenidor s'evidencia en analitzar l'evolució del tràfic portuari de contenidors, que ha estat creixent a ritmes superiors al 10 % superant els 600 milions TEU des de 2012. El contenidor és, per tant, un element clau de les cadenes subministrament globals i la logística del contenidor és un àrea d'estudi i treball d'enorme interès per l'impacte que té en l'eficiència d'aquestes cadenes, pel cost que suposa a navilieres i operadors en els seus comptes d'explotació (cost que es trasllada a l'usuari final i repercuteix en el preu de les mercaderies transportades) i pel cost social i ambiental associat a les externalitats del transport derivades d'aquesta gestió de la flota de contenidors. La logística del contenidor té a veure amb la gestió eficient del parc de contenidors, minimitzant els costos de transport, emmagatzematge i manteniment, i maximitzant la utilització de l'equip. En la logística del contenidor es poden identificar, en general, dues categories o nivells diferenciats en funció de l'àmbit geogràfic i de les modalitats de transport implicats: el nivell internacional i el nivell local o regional. Aquest treball aborda la logística del contenidor a nivell regional o local, és a dir, quant a la gestió de l'estoc, transport i moviments interiors, tractant de donar resposta i plantejar solucions a alguns dels problemes amb els quals es troba el sector logístic-portuari en l'actualitat. El resultat de la recerca permet, en primer lloc, conèixer d'una forma integral i estructurada la complexitat de la logística del contenidor marítim. En segon lloc, s'identifiquen i aborden problemes específics reals per a la seua modelització i anàlisi, que permeten contribuir a la millora del sistema logístic actual. En concret s'aborden els següents problemes: -Problemes d'elecció modal en la configuració de les cadenes o corredors logístics interiors en el transport de contenidors marítims. -Problemes de localització o vertebració d'una xarxa d'infraestructures nodals per a atendre les necessitats logístiques dels contenidors marítims. -Problemes associats als moviments en buit i gestió de contenidors marítims. L'interès i contribució acadèmica d'aquest treball resideix tant en la definició i modelització dels problemes específics amb una profunda discussió teòrica, com en l'aplicació empírica a situacions i entorns reals, cosa que ha sigut possible gràcies al contacte directe de l'autor amb el sector logístic-portuari i la seua participació en nombrosos projectes de consultoria i recerca tant en el clúster del Port de València com a nivell europeu i internacional. El treball es planteja com una col·lecció de sis articles científics. L'ordre en què estan situats els articles en la tesi permet mantenir una seqüència lògica construïda a posteriori i no segons l'ordre cronològic en el qual van ser publicats. / Furió Pruñonosa, S.

This Master’s thesis is focused on the suspension of the front wheel, more accurately for specific part, upright. It describes the basic requirements for construction, distribution of uprights, their method of production and types of materials used. It briefly mentions topology optimization and its two optimization methods. Also deals with vehicle dynamics for driving conditions – standing vehicle, braking and cornering. In the practical part, the work is focused on determining the load effects on the upright during the aforementioned driving conditions using MBS software. At the end of the work, FEM stress and deformation analyses are performed for loading on the wheel side and on the suspension side, which are then compared and evaluated.

The master thesis focuses on the design and implementation of data collection from production using a PLC into an SQL database located in the cloud and subsequent visualization. The work describes the applicable communication protocols MQTT and OPC UA with the fact that the protocol MQTT was selected. It deals with securing data transfer from the line to the cloud using the TLS protocol. The individual cloud services and their possibilities for data collection are described here. The work deals with the possibilities of data visualization using existing open source solutions and the differences between them. I describe the possibilities of modifying the open source environment of the Grafany project. Real dashboards from production are presented. The data collection system was deployed in two plants for testing.

The aim of this work was to create a design of a gear coupling for railway vehicle application. The work presents a comprehensive view of this issue. First of all, a brief theoretical introduction to the issue is made. The practical part follows, where the design of the whole coupling and especially the newly designed solutions are described in detail. The strength analysis performed deal with the key components that are necessary to ensure safe operation. These analyses can be applied not only for this particular case, but also to gear couplings of different designs, because in principle these calculations do not differ much. In the last chapter, which deals with the dynamic model, all the theoretical assumptions are verified, especially the coupling movements and the applied loads. If the reader deals with the issue of gear couplings, not only in the railway industry, this work presents a comprehensive view of this component. The designed coupling and all performed simulations are really usable in operation.

Under de senaste åren har finanssektorn förändrats och en bidragande faktor är teknisk innovation. Teknisk innovation kan utveckla tillhandahållandet av finansiella tjänster som finansiella aktörer såsom banker erbjuder till sina kunder. En jurisdiktion kan främja utvecklingen av finansiella tjänster, antingen genom en finansiell sandlåda eller en innovationshubb. En finansiell sandlåda är en säker miljö där banker och bolag vars verksamhet endast består av teknisk innovation (FinTech-bolag), kan testa sina oreglerade affärsmodeller. Testutrymmet kontrolleras av en tillsynsmyndighet. För närvarande har över 50 jurisdiktioner upprättat en finansiell sandlåda och flera europeiska länder har redan en sandlåda i drift eller överväger att införa en. Flera olika EU-institut, som exempelvis Europeiska kommissionen och Europaparlamentet, är positiva för att införa en reglering av finansiella sandlådor på EU-nivå. Finansiella sandlådor är endast utformade som nationella finansiella sandlådor. Syftet med denna masteruppsats är att utreda huruvida EU behöver reglera finansiella sandlådor och i så fall om regelverket bör antas som ett direktiv eller en förordning. Slutsatsen av denna uppsats är att finansiella sandlådor behöver regleras även om vissa medlemsstater inte vill upprätta en egen nationell sandlåda. En anledning till varför finansiella sandlådor är behövliga i EU är för att de främjar konkurrensen mellan olika finansiella aktörer. Dessutom är finansiella sandlådor ett tillfälle för nya marknadsaktörer såsom FinTech-bolag att växa. Väljer EU att inte reglera finansiella sandlådor kommer det att hämma den fria rörligheten för finansiella tjänster. Den mest effektiva lösningen för EU hade varit att anta ett direktiv om harmoniserade nationella finansiella sandlådor. Genom att anta regelverket som ett direktiv får medlemsländerna själva bestämma vilka bestämmelser som ska implementeras i den nationella lagstiftningen. / In recent times, the financial market has changed and a contributing factor is technological innovation. Technological innovation can develop the provision of financial services which companies such as banks offers their consumers. There are two ways a jurisdiction can promote the development of financial services; either through a regulatory sandbox or an innovation hub. A regulatory sandbox is a safe environment where banks and companies who only works with technological innovation (FinTech-companies) can test their unregulated business models. The environment is controlled and monitored by a supervisory authority. Regulatory sandboxes are available in more than 50 different jurisdictions, and an increasing number of European countries are either thinking of establishing one or have already done it.   Within the European Union, some organisations such as the European Commission and the European Parliament have expressed their willingness to regulate regulatory sandboxes at Union level. For now, sandboxes can only be set up as a national regulatory sandbox. The purpose of this master’s thesis is to investigate whether the Union needs to regulate regulatory sandboxes and if so, should the Union introduce a directive or a regulation on harmonized national regulatory sandboxes.    The investigation of this thesis shows that regulatory sandboxes are needed even though some Member States are unwilling to establish one. Regulatory sandboxes are needed in the Union because it furthers the competition between companies offering financial services. Regulatory sandboxes also help new entrants such as FinTech-companies to grow. If the Union does not regulate regulatory sandboxes, it will hinder the free movement of services. The best outcome for regulation, would be if the Union adopted a directive on harmonized national regulatory sandboxes. The regulation should be adopted as a directive because it facilitates Member States in determining which provisions should be implemented in national legislation.
