Process of Expropriation of Buildings for the Construction of the New Dock of the Port of Cartagena (Spain) in the 18th Century

The need of the Bourbon monarchy to build a Naval Base in the Bay of Cartagena (Spain) during the eighteenth century, implied performing various actions on the environment which allowed the construction of the new dock. One of the priority actions was the transformation of the watershed of the streams that flowed into Mandaraches´s sea. For this reason, a dike was designed and constructed in the northern part of the city. The design of this great work, which was designed as a fortification of the city, was subject to considerable uncertainties. Its proximity to the city involved the demolition of several buildings in the San Roque´s neighborhood. The greater or lesser number of affected buildings and the value of the just indemnification for the expropriation of them, become decisive factors to determine if the work was viable for the Royal Estate or not.

Container Terminal Simulation. A case study: port of Valencia.

This paper is concerned with the study of non-Markovian queuing systems in container terminals. The methodology presented has been applied to analyze the ship traffic in the port of Valencia located in the Western Mediterranean. Two container terminals have been studied: the public container terminal of NOATUM and the dedicated container terminal of MSC. This paper contains the results of a simulation model based on queuing theory. The methodology presented is found to be effective in replicating realistic ship traffic operations in port as well as in conducting capacity evaluations. Thus the methodology can be used for capacity planning (long term), tactical planning (medium term) and even for the container terminal design (port enlargement purposes).

Port planning for the Port of Vigo using port and city integration criteria

Project planning and architectural management of a port area should include many variables, it must be in harmony with its environment and its historical development as the key to successful integration. This article explains the elements which should be taken into account when doing such planning by describing the proposal presented on the ?Concurso public internacional de ideas para proyectar la ordenación urbanística y arquitectónica del área central del puerto de Vigo?, with the aim of sharing comprehensive applied design philosofy, it will inspire and help future designers. Creative imagination is great added value to engineering creations, but should not overwhelm functionality and sustainability, but to be in harmony with them. The maximum aesthetic expression in engineering is achieved as the product of the conceptual elegance of the functionality of the structures.

Cyclic behaviour of saturated sands subject to previous horizontal shear stresses

The dynamic behaviour of saturated sands has been studied from different perspectives. However, most experimental research on this field does not take into account the shear stress conditions existing prior to the application of dynamic loads; i.e., a null initial static shear stress (τo = 0) is assumed. The main objective of this work is to report on the influence that static shear stresses (τo) have on the behaviour of saturated sands under cyclic shear loads. This article presents the results and analysis of part of a wider experimental programme involving 30 monotonic and 26 cyclic simple shear tests for different combinations of static shear stress (τo) and cyclic shear stress (τc) (all undrained), besides identification and classification tests. The tested samples have been taken from the area of the North Entrance Mouth at the Port of Barcelona (Spain).

A model of economic management of cultural heritage: the rehabilitation of fort christmas as an interpretation center of defensive architecture of the Mediterranean in Cartagena (Spain)

The Cultural Heritage constitutes a way to generate social identities and play an important role in the development of the Spanish Mediterranean cities that opt to sustainable quality tourism. The reflection on the necessity of intervention on this heritage, in addition to establishing what should be done, brings up the need to define the reasons for taking action, why and what-for. These decisions are essential to establish if its maintenance and recovery are economically sustainable. The Project "Cartagena Port of Cultures", with support from the European Union, is an example of effective instrument for ensuring the sustainability of our built heritage conservation. Its main objective was to enable sustainable development of tourism in Cartagena based on sustainability and seasonality. This was achieved through a process of recovery of heritage resources and their optimum promotion and marketing.

Every day information technology plays a greater role in our lives, from our homes to businesses, to how governments access large volumes of data and information. Communication is no longer hindered by distances, as a buyer and seller can be anywhere. A product that is purchased in a shop in Santiago through a payment option (credit card) in less than a second, a transaction will request authorization from Chile to Singapore to be approved. In this society both buyers and sellers have access to online information that is available for decision making. There is greater openness and economic integration that has begun within the commercial networks, in which there are regional and multilateral approaches that has helped expand trade and economic integration. Likewise, there are numerous free trade agreements that support economic development; however, the global crisis has affected economies like transportation. In regards to international commerce about 90% is developed through the ports, considering that the former is important to identify the relationships between the development of the payment options and e-commerce at the ports. Our research aims to integrate both the scientific research and applied research aspects, so that this will be a contribution to the day to day business for the payment options in Chile, and for those who design and define the application of norms and standards.

Therefore, through the use of this methodology we look to be able to make better decisions in the payment options industry in Chile, with better management and use of the resources.

Coeficientes de presión intersticial en el aparato de corte simple = Pore pressure coefficients for simple shear test

La actuación de cargas sobre un suelo saturado, produce, en función de la naturaleza de la solicitación, del tipo de suelo y de las condiciones de drenaje del terreno, un incremento de la presión sobre el agua de los intersticios. Se ha abordado el estudio de la generación de dicha presión intersticial a partir de muestras de suelo blando, normalmente consolidadas, procedentes del subsuelo del Puerto de Barcelona. Para ello se han utilizado los datos de una completa campaña experimental utilizando la máquina de ensayo de corte simple, y tras la adecuada interpretación del ensayo, se identifican los aspectos que se consideran clave para el proceso de generación de presión intersticial en el suelo, según las diferentes situaciones de carga actuante. Como conclusión, se plantea la generalización de la clásica ecuación que Skempton formuló hace casi 60 años y que permite interpretar la generación de presión intersticial para el aparato de ensayo triaxial. ncrease in pore pressure depending on the nature of the excitation, the type of soil and the drainage conditions of the ground are generated by loads acting on a saturated soil. It has approached the study of the generation of the pore pressure from usually consolidated soft soil samples from the basement of the Port of Barcelona. Data from an adequate experimental campaign using simple shear machine have been used, and the aspects that are considered key to the process of generation of pore pressure in the soil under different loading conditions acting have been identified. In conclusion, the generalization of Skempton's classical equation (formulated almost 60 years ago) and the interpretation of the pore pressure generation for triaxial test apparatus have been proposed.

Coastal Impacts Around Guadiaro River Mouth (Spain)

The “Port of Sotogrande” Beach (San Roque, Cadiz, Spain) has suffered significant erosion and changes since the construction of the marina and port of Sotogrande (San Roque, Cadiz, Spain). This paper reviews the dynamical processes on Guadiaro front and establishes relationship between them. It sets from a comparative evolution of the Alboran Sea Coast outlets and bays since the Little Ice Age, which shows that the Guadiaro estuary has remained functional while all other Alboran fluvial estuaries silted to son. The study shows the evidences of the coastal impacts around the mouth, even further than mouth littoral barriers, of the port infrastructures; and it provides new elements to understand the dynamical processes on the mouth and surroundings as well. That should be fundamental for shore protection along the whole coastal stretch

Estudio dinámico de cimentaciones en obras portuarias

Los diques de abrigo verticales son estructuras monolíticas que sirven para reflejar el oleaje creando, de este modo, una zona abrigada en el lado tierra. Son estructuras de contención de gravedad, es decir, su peso es el elemento resistente fundamental. Las solicitaciones sobre estas estructuras son de tipo dinámico (oleaje) y consisten, fundamentalmente, en un empuje frontal y una subpresión en la base que varían en el tiempo. Habitualmente, las acciones sobre los diques de abrigo se establecen mediante fórmulas empíricas, que se describen en la presente tesis si bien, para obras de especial importancia, suelen medirse en modelos reducidos de laboratorio. Cuando el cimiento en que han de apoyarse estas estructuras no presenta una resistencia al corte suficiente, el apoyo se realiza en banquetas que redistribuyen la carga y que están formadas por materiales granulares. En la práctica habitual para conocer la estabilidad de estas estructuras frente a un temporal, tras establecer las acciones de cálculo (empuje frontal y subpresión) se efectúa un cálculo pseudoestático en el que se consideran condiciones drenadas o no drenadas del cimiento en función de su permeabilidad. Se conoce que en los suelos saturados, bajo cargas cíclicas, tiende a producirse una elevación de las presiones intersticiales y una reducción de tensiones efectivas así como una degradación del módulo de deformación tangencial en función del número de ciclos de carga, pudiéndose producir el fenómeno conocido como licuefacción (arenas) o movilidad cíclica (suelos más finos). El objeto de la tesis es explorar la posibilidad, con la tecnología actual, de analizar la estabilidad de los diques de abrigo verticales en cuyo cimiento existen suelos blandos, proponiendo un procedimiento para evaluar la estabilidad dinámica en este tipo de obras. Para ello se han revisado los procedimientos actualmente utilizados para definir las acciones de cálculo, los principales modelos de comportamiento dinámicos de suelos saturados disponibles y los procedimientos de cálculo. Una vez investigado el estado del arte sobre este tema, se propone un procedimiento de cálculo en el que, utilizando el programa comercial FLAC, se establecen las acciones cíclicas sobre un dique de abrigo vertical tipo con distintas condiciones de apoyo, aplicando, para el cimiento, un modelo de comportamiento tipo hiperbólico con generación de presiones intersticiales cuyos parámetros pueden obtenerse de ensayos de campo y laboratorio. Por último, una vez descrito el procedimiento, se aplica a un caso real en el que se produjo un fallo en la cimentación que desembocó en el hundimiento de parte de un dique vertical situado en el puerto de Barcelona, presentándose los resultados obtenidos del análisis efectuado y comparándolos con los obtenidos utilizando los métodos de cálculo habituales. Vertical breakwaters are monolithic structures built to reflect sea waves, thereby providing a sheltered area on the land side. They are gravity retaining structures, that is, their own weight is their basic resisting mechanism. Loads acting on these structures are dynamic (waves) and consist essentially in a frontal thrust and an uplift pressure on the base, which both vary over time. Usually, actions in breakwater design are established by empirical formulas, which are described in this thesis. For works of particular importance, such forces are measured in small-scale laboratory tests. When there are no soils with enough shear strength under the planned vertical breakwaters, they usually rest on granular berms which redistribute the load. Nowadays, after establishing the acting forces on the breakwater (front push and uplift pressure), a pseudostatic calculation (with drained or undrained conditions depending on the foundation permeability) is normally done to analyze the stability of these structures against storm waves. It is known that pore pressures tend to rise in saturated soils under cyclic loading and, consequently, there is a reduction of effective stress. A degradation of the shear modulus also occurs depending on the number of load cycles. All of these effects can bring about the phenomenon known as liquefaction in sands or cyclic mobility in fine-grained soils. The aim of the thesis is to explore the possibility that current technology provides to analyze the stability of vertical breakwaters founded on soft soils, and to suggest a method to evaluate the dynamic stability in this type of works. To this end, a review has been made of procedures currently used to define the actions in calculations, the main models of dynamic behaviour of saturated soils available and of calculation procedures. Once the state of the art on this subject has been reviewed, a method of calculation is proposed that uses the commercial program FLAC and is applied to a typical vertical breakwater on a range of different foundation conditions. For the foundation soil, a hyperbolic constitutive model with pore pressure generation has been employed, whose parameters can be obtained from field and laboratory tests. Finally, the described procedure is applied to an actual case where a foundation failure occurred that led to the sinking of several caissons in a vertical breakwater located in the port of Barcelona. The results obtained with the proposed method are compared with those obtained using conventional methods.

La Península Ibérica en el transporte masivo de mercancías entre Europa y África : futuras autopistas del mar

La competitividad del transporte de mercancías depende del estado y funcionamiento de las redes existentes y de sus infraestructuras, no del modo de transporte. En concreto, la rentabilidad o la reducción de los costes de producción del transporte marítimo se vería incrementado con el uso de buques de mayor capacidad y con el desarrollo de plataformas portuarias de distribución o puertos secos, ya que el 90% del comercio entre la Unión Europea y terceros países se realiza a través de sus puertos a un promedio de 3,2 billones de toneladas de mercancías manipuladas cada año y el 40% del tráfico intraeuropeo utiliza el transporte marítimo de corta distancia. A pesar de que los puertos europeos acogen anualmente a más de 400 millones de pasajeros, los grandes desarrollos se han producido en los puertos del norte de Europa (Róterdam, Amberes, Ámsterdam). Los países del Sur de Europa deben buscar nuevas fórmulas para ser más competitivos, ya sea mediante creación de nuevas infraestructuras o mediante refuerzo de las existentes, ofreciendo los costes de los puertos del Norte. El fomento del transporte marítimo y fluvial como alternativa al transporte por carretera, especialmente el transporte marítimo de corta distancia, ha sido impulsado por la Comisión Europea (CE) desde 2003 a través de programas de apoyo comunitario de aplicación directa a las Autopistas del Mar, a modo de ejemplo, cabría citar los programas Marco Polo I y II, los cuales contaron con una dotación presupuestaria total de 855 millones de euros para el período 2003 – 2013; en ese período de tiempo se establecieron objetivos de reducción de congestión vial y mejora del comportamiento medio ambiental del sistema de transporte de mercancías dentro de la comunidad y la potenciación de la intermodalidad. El concepto de Autopista del Mar surge en el Libro Blanco de Transportes de la Comisión Europea “La política europea de transportes de cara al 2010: La hora de la verdad” del 12 de diciembre de 2001, en el marco de una política europea para fomento y desarrollo de sistemas de transportes sostenibles. Las Autopistas del Mar consisten en rutas marítimas de corta distancia entre dos puntos, de menor distancia que por vía terrestre, en las que a través del transporte intermodal mejoran significativamente los tiempos y costes de la cadena logística, contribuyen a la reducción de accidentes, ruidos y emisiones de CO2 a la atmósfera, permite que los conductores pierdan horas de trabajo al volante y evita el deterioro de las infraestructuras terrestres, con el consiguiente ahorro en mantenimiento. La viabilidad de una Autopista del Mar depende tanto de factores de ubicación geográficos, como de características propias del puerto, pasando por los diferentes requerimientos del mercado en cada momento (energéticos, medio ambientales y tecnológicos). Existe un elemento nuevo creado por la Comisión Europea: la red transeuropea de transportes (RTE-T). En el caso de España, con sus dos accesos por los Pirineos (La Junquera e Irún) como únicos pasos terrestres de comunicación con el continente y con importantes limitaciones ferroviarias debido a los tres anchos de vía distintos, le resta competitividad frente al conjunto europeo; por el contrario, España es el país europeo con más kilómetros de costa (con más de 8.000 km) y con un emplazamiento geográfico estratégico, lo que le convierte en una plataforma logística para todo el sur de Europa, por lo que las Autopistas del Mar tendrán un papel importante y casi obligado para el desarrollo de los grandes corredores marítimos que promueve Europa. De hecho, Gijón y Vigo lo han hecho muy bien con sus respectivas líneas definidas como Autopistas del Mar y que conectan con el puerto francés de Nantes-Saint Nazaire, ya que desde ahí los camiones pueden coger rutas hacia el Norte. Paralelamente, la Unión Europea ha iniciado los pasos para el impulso de la primera Autopista del Mar que conectará España con el mercado de Reino Unido, concretamente los Puertos de Bilbao y Tilbury. Además, España e Italia sellaron un acuerdo internacional para desarrollar Autopistas del Mar entre ambos países, comprometiéndose a impulsar una docena de rutas entre puertos del litoral mediterráneo español y el italiano. Actualmente, están en funcionando los trayectos como Barcelona-Génova, Valencia-Civitavecchia y Alicante- Nápoles, notablemente más cortos por mar que por carretera. Bruselas identificó cuatro grandes corredores marítimos que podrían concentrar una alta densidad de tráfico de buques, y en dos de ellos España ya tenía desde un principio un papel crucial. La Comisión diseñó el 14 de abril de 2004, a través del proyecto West-Mos, una red de tráfico marítimo que tiene como vías fundamentales la denominada Autopista del Báltico (que enlaza Europa central y occidental con los países bálticos), la Autopista de Europa suroriental (que une el Adriático con el Jónico y el Mediterráneo más oriental) y también la Autopista de Europa occidental y la Autopista de Europa suroccidental (que enlazan España con Reino Unido y la Francia atlántica y con la Francia mediterránea e Italia, respectivamente). Para poder establecer Autopistas del Mar entre la Península Ibérica y el Norte de Europa primará especialmente la retirada de camiones en la frontera pirenaica, donde el tráfico pesado tiene actualmente una intensidad media diaria de 8.000 unidades, actuando sobre los puntos de mayor congestión, como por ejemplo los Alpes, los Pirineos, el Canal de la Mancha, las carreteras fronterizas de Francia y Euskadi, y proponiendo el traslado de las mercancías en barcos o en trenes. Por su parte, para contar con los subsidios y apoyos europeos las rutas seleccionadas como Autopistas del Mar deben mantener una serie de criterios de calidad relacionados con la frecuencia, coste “plataforma logística a plataforma logística”, simplicidad en procedimientos administrativos y participación de varios países, entre otros. Los estudios consideran inicialmente viables los tramos marítimos superiores a 450 millas, con un volumen de unas 15.000 plataformas al año y que dispongan de eficientes comunicaciones desde el puerto a las redes transeuropeas de autopistas y ferrocarril. Otro objetivo de las Autopistas del Mar es desarrollar las capacidades portuarias de forma que se puedan conectar mejor las regiones periféricas a escala del continente europeo. En lo que a Puertos se refiere, las terminales en los muelles deben contar con una línea de atraque de 250 m., un calado superior a 8 m., una rampa “ro-ro” de doble calzada, grúas portainer, y garantizar operatividad para un mínimo de dos frecuencias de carga semanales. El 28 de marzo de 2011 se publicó el segundo Libro Blanco sobre el futuro del transporte en Europa “Hoja de ruta hacia un espacio único europeo de transporte: por una política de transportes competitiva y sostenible”, donde se definió el marco general de las acciones a emprender en los próximos diez años en el ámbito de las infraestructuras de transporte, la legislación del mercado interior, la reducción de la dependencia del carbono, la tecnología para la gestión del tráfico y los vehículos limpios, así como la estandarización de los distintos mercados. Entre los principales desafíos se encuentran la eliminación de los cuellos de botella y obstáculos diversos de nuestra red europea de transporte, minimizar la dependencia del petróleo, reducir las emisiones de GEI en un 60% para 2050 con respecto a los niveles de 1990 y la inversión en nuevas tecnologías e infraestructuras que reduzcan estas emisiones de transporte en la UE. La conexión entre la UE y el norte de África provoca elevados niveles de congestión en los puntos más críticos del trayecto: frontera hispano-francesa, corredor del Mediterráneo y el paso del estrecho. A esto se le añade el hecho de que el sector del transporte por carretera está sujeto a una creciente competencia de mercado motivada por la eliminación de las barreras europeas, mayores exigencias de los cargadores, mayores restricciones a los conductores y aumento del precio del gasóleo. Por otro lado, el mercado potencial de pasajeros tiene una clara diferenciación en tipos de flujos: los flujos en el período extraordinario de la Operación Paso del Estrecho (OPE), enfocado principalmente a marroquíes que vuelven a su país de vacaciones; y los flujos en el período ordinario, enfocado a la movilidad global de la población. Por tanto, lo que se pretende conseguir con este estudio es analizar la situación actual del tráfico de mercancías y pasajeros con origen o destino la península ibérica y sus causas, así como la investigación de las ventajas de la creación de una conexión marítima (Autopista del Mar) con el Norte de África, basándose en los condicionantes técnicos, administrativos, económicos, políticos, sociales y medio ambientales. The competitiveness of freight transport depends on the condition and operation of existing networks and infrastructure, not the mode of transport. In particular, profitability could be increased or production costs of maritime transport could be reduced by using vessels with greater capacity and developing port distribution platforms or dry ports, seeing as 90% of trade between the European Union and third countries happens through its ports. On average 3,2 billion tonnes of freight are handled annualy and 40% of intra-European traffic uses Short Sea Shipping. In spite of European ports annually hosting more than 400 million passengers, there have been major developments in the northern European ports (Rotterdam, Antwerp, Amsterdam). Southern European countries need to find new ways to be more competitive, either by building new infrastructure or by strengthening existing infrastructure, offering costs northern ports. The use of maritime and river transport as an alternative to road transport, especially Short Sea Shipping, has been driven by the European Commission (EC) from 2003 through community support programs for the Motorways of the Sea. These programs include, for example, the Marco Polo I and II programs, which had a total budget of 855 million euros for the period 2003-2013. During this time objectives were set for reducing road congestion, improving the environmental performance of the freight transport system within the community and enhancing intermodal transport. The “Motorway of the Sea” concept arises in the European Commission’s Transport White Paper "European transport policy for 2010: time to decide" on 12 December 2001, as part of a European policy for the development and promotion of sustainable transport systems. A Motorway of the Sea is defined as a short sea route between two points, covering less distance than by road, which provides a significant improvement in intermodal transport times and to the cost supply chain. It contributes to reducing accidents, noise and CO2 emissions, allows drivers to shorten their driving time and prevents the deterioration of land infrastructure thereby saving on maintenance costs. The viability of a Motorway of the Sea depends as much on geographical location factors as on characteristics of the port, taking into account the different market requirements at all times (energy, environmental and technological). There is a new element created by the European Commission: the trans-European transport network (TEN-T). In the case of Spain, with its two access points in the Pyrenees (La Junquera and Irun) as the only land crossings connected to the mainland and major railway limitations due to the three different gauges, it appears less competitive compared to Europe as a whole. However, Spain is the European country with the most kilometers of coastline (over 8,000 km) and a strategic geographical location, which makes it a logistics platform for the all of Southern Europe. This is why the Motorways of the Sea will have an important role, and an almost necessary one to develop major maritime corridors that Europe supports. In fact, Gijon and Vigo have done very well with their respective sea lanes defined as Motorways of the Sea and which connect with the French port of Nantes-Saint Nazaire, as from there trucks can use nort-heading routes. In parallel, the European Union has taken the first steps to boost the first Motorway of the Sea linking Spain to the UK market, specifically the ports of Bilbao and Tilbury. Furthermore, Spain and Italy sealed an international agreement to develop Motorways of the Sea between both countries, pledging to develop a dozen routes between ports on the Spanish and Italian Mediterranean coasts. Currently, there are sea lanes already in use such as Barcelona-Genova, Valencia-Civitavecchia and Alicante-Naples, these are significantly shorter routes by sea than by road. Brussels identified four major maritime corridors that could hold heavy concentrate shipping traffic, and Spain had a crucial role in two of these from the beginning. On 14 April 2004 the Commission planned through the West-Mos project, a network of maritime traffic which includes the essential sea passages the so-called Baltic Motorway (linking Central and Western Europe with the Baltic countries), the southeast Europe Motorway (linking the Adriatic to the Ionian and eastern Mediterranean Sea), the Western Europe Motorway and southwestern Europe Motorway (that links Spain with Britain and the Atlantic coast of France and with the French Mediterranean coast and Italy, respectively). In order to establish Motorways of the Sea between the Iberian Peninsula and Northern Europe especially, it is necessary to remove trucks from the Pyrenean border, where sees heavy traffic (on average 8000 trucks per day) and addressing the points of greatest congestion, such as the Alps, the Pyrenees, the English Channel, the border roads of France and Euskadi, and proposing the transfer of freight on ships or trains. For its part, in order to receive subsidies and support from the European Commission, the routes selected as Motorways of the Sea should maintain a series of quality criteria related to frequency, costs "from logistics platform to logistics platform," simplicity in administrative procedures and participation of several countries, among others. To begin with, studies consider viable a maritime stretch of at least 450 miles with a volume of about 15,000 platforms per year and that have efficient connections from port to trans-European motorways and rail networks. Another objective of the Motorways of the Sea is to develop port capacity so that they can better connect peripheral regions across the European continent. Referring ports, the terminals at the docks must have a berthing line of 250 m., a draft greater than 8 m, a dual carriageway "ro-ro" ramp, portainer cranes, and ensure operability for a minimum of two loads per week. On 28 March 2011 the second White Paper about the future of transport in Europe "Roadmap to a Single European Transport Area – Towards a competitive and resource efficient transport system" was published. In this Paper the general framework of actions to be undertaken in the next ten years in the field of transport infrastructure was defined, including internal market legislation, reduction of carbon dependency, traffic management technology and clean vehicles, as well as the standardization of different markets. The main challenges are how to eliminate bottlenecks and various obstacles in our European transport network, minimize dependence on oil, reduce GHG emissions by 60% by 2050 compared to 1990 levels and encourage investment in new technologies and infrastructure that reduce EU transport emissions. The connection between the EU and North Africa causes high levels of congestion on the most critical points of the journey: the Spanish-French border, the Mediterranean corridor and Gibraltar Strait. In addition to this, the road transport sector is subject to increased market competition motivated by the elimination of European barriers, greater demands of shippers, greater restrictions on drivers and an increase in the price of diesel. On the other hand, the potential passenger market has a clear differentiation in type of flows: flows in the special period of the Crossing the Straits Operation (CSO), mainly focused on Moroccans who return home on vacation; and flows in the regular session, focused on the global mobile population. Therefore, what I want to achieve with this study is present an analysis of the current situation of freight and passengers to or from the Iberian Peninsula and their causes, as well as present research on the advantages of creating a maritime connection (Motorways of the Sea) with North Africa, based on the technical, administrative, economic, political, social and environmental conditions.

Diseño de un sistema regional de alerta de tsunamis como parte integral de la operación portuaria

En este trabajo se presenta el desarrollo de una metodología para obtener un universo de funciones de Green y el algoritmo correspondiente, para estimar la altura de tsunamis a lo largo de la costa occidental de México en función del momento sísmico y de la extensión del área de ruptura de sismos interplaca localizados entre la costa y la Trinchera Mesoamericana. Tomando como caso de estudio el sismo ocurrido el 9 de octubre de 1995 en la costa de Jalisco-Colima, se estudiaron los efectos del tsunami originados en la hidrodinámica del Puerto de Manzanillo, México, con una propuesta metodológica que contempló lo siguiente: El primer paso de la metodología contempló la aplicación del método inverso de tsunamis para acotar los parámetros de la fuente sísmica mediante la confección de un universo de funciones de Green para la costa occidental de México. Tanto el momento sísmico como la localización y extensión del área de ruptura de sismos se prescribe en segmentos de planos de falla de 30 X 30 km. A cada uno de estos segmentos del plano de falla corresponde un conjunto de funciones de Green ubicadas en la isobata de 100 m, para 172 localidades a lo largo de la costa, separadas en promedio 12 km entre una y otra. El segundo paso de la metodología contempló el estudio de la hidrodinámica (velocidades de las corrientes y niveles del mar en el interior del puerto y el estudio del runup en la playa) originada por el tsunami, la cual se estudió en un modelo hidráulico de fondo fijo y en un modelo numérico, representando un tsunami sintético en la profundidad de 34 m como condición inicial, el cual se propagó a la costa con una señal de onda solitaria. Como resultado de la hidrodinámica del puerto de Manzanillo, se realizó un análisis de riesgo para la definición de las condiciones operativas del puerto en términos de las velocidades en el interior del mismo, y partiendo de las condiciones iniciales del terremoto de 1995, se definieron las condiciones límites de operación de los barcos en el interior y exterior del puerto. In this work is presented the development of a methodology in order to obtain a universe of Green's functions and the corresponding algorithm in order to estimate the tsunami wave height along the west coast of Mexico, in terms of seismic moment and the extent of the area of the rupture, in the interplate earthquakes located between the coast and the Middle America Trench. Taking as a case of study the earthquake occurred on October 9, 1995 on the coast of Jalisco-Colima, were studied the hydrodynamics effects of the tsunami caused in the Port of Manzanillo, Mexico, with a methodology that contemplated the following The first step of the methodology contemplated the implementation of the tsunami inverse method to narrow the parameters of the seismic source through the creation of a universe of Green's functions for the west coast of Mexico. Both the seismic moment as the location and extent of earthquake rupture area prescribed in segments fault planes of 30 X 30 km. Each of these segments of the fault plane corresponds a set of Green's functions located in the 100 m isobath, to 172 locations along the coast, separated on average 12 km from each other. The second step of the methodology contemplated the study of the hydrodynamics (speed and directions of currents and sea levels within the port and the study of the runup on the beach Las Brisas) caused by the tsunami, which was studied in a hydraulic model of fix bed and in a numerical model, representing a synthetic tsunami in the depth of 34 m as an initial condition which spread to the coast with a solitary wave signal. As a result of the hydrodynamics of the port of Manzanillo, a risk analysis to define the operating conditions of the port in terms of the velocities in the inner and outside of the port was made, taken in account the initial conditions of the earthquake and tsunami ocurred in Manzanillo port in 1995, were defined the limits conditions of operation of the ships inside and outside the port.

Improving the competitiveness of the Spanish port system by optimising the cargo handling service

Port services, and in particular the cargo handling service, are responsible for the greatest share of costs incurred during the passage of cargo through a port. The provision of these services reliably and efficiently is crucial in a sector in which there is great opacity. This study has provided the responsible administration ? the Port Authority ? with a tool enabling objective decision making both when it comes to issuing the corresponding licenses and during the period of service provision. Furthermore, we have proposed a series of measures whose application would improve the conditions of service provision and reduce the costs incurred by the passage of cargo through the port.

Use of a scrapped ship as a floating breakwater for shore protection

The purpose of this research is to assess the effectiveness of a ship used as a detached floating breakwater for coastal protection and forming salients of sand or tombolos. Floating breakwaters have been extensively used as port or coastal protection structures and display advantages in terms of construction and ecology, amongst others. However, the greatest problem these structures present is the limited range of wave heights and periods for which they are really effective. Furthermore, ships may be considered as floating structures which, used as breakwaters, would keep the advantages of floating breakwaters and would increase their range of applicability. The possibility of using ships at the conclusion of their useful life for this purpose would also involve greater economic and environmental advantages. Tests were carried out to assess the ship’s effectiveness as a detached floating breakwater using a scaled down physical model to determine the vessel’s transmission coefficient (Kt) as to regular waves with significant periods of 5 sec to 12 sec and significant wave heights of 1.5 m to 4 m at depths from 20 m to 35 m. The ship proves effective for waves up to 4 m significant height and significant periods up to 9 sec. Hanson and Kraus and Pilarzyk’s analytical models, which take transmission coefficients into account, were used to analyse the shore’s response to the breakwater protection. The results obtained show that salients form for waves with periods between 6 sec and 9 sec. It is also concluded that the depths tested are far different from the more usual shallow water involved in constructing detached breakwaters and the shore’s response is therefore scarce.

This paper shows the Gini Coefficient, the dissimilarity Index and the Lorenz Curve for the Spanish Port System by type of goods from 1960 to the year 2010 for business units: Total traffic, Liquid bulk cargo, Solid bulk cargo, General Merchandise and Container (TEUs) with the aim of carcaterizar the Spanish port systems in these periods and propose future strategies.

Proof of concept of an imaging system demonstrator for PET applications with SiPM

A PET imaging system demonstrator based on LYSO crystal arrays coupled to SiPM matrices is under construction at the University and INFN of Pisa. Two SiPM matrices, composed of 8×8 SiPM pixels, and 1,5 mm pitch, have been coupled one to one to a LYSO crystals array and read out by a custom electronics system. front-end ASICs were used to read 8 channels of each matrix. Data from each front-end were multiplexed and sent to a DAQ board for the digital conversion; a motherboard collects the data and communicates with a host computer through a USB port for the storage and off-line data processing. In this paper we show the first preliminary tomographic image of a point-like radioactive source acquired with part of the two detection heads in time coincidence.
