Maybe some of you have already seen it on the media, but for those still unaware… Valladolid has launched the world’s first smart pedestrian crossing!!!
Within the framework of the VRUITS European Project (Improving the safety and mobility of vulnerable road users through ITS applications), and thanks to the close collaboration with the Valladolid City Council, CIDAUT has installed an intelligent system that solves the problem of people detection and counting in all kind of environments using a brand new technology. This idea of measuring and monitoring people flow was found very appealing in order to improve urban mobility and the system quickly found its way on the crossing between the streets Claudio Moyano and Santiago, one of the most crowded spots in Valladolid city centre.
The aim of the installation was on one the hand detect and count pedestrians on Calle Santiago, to measure people flow and see how it varies depending on the time of day and from one day to another. The system is also able to distinguish different directions, allowing making statistics of people following one sense or another separately. On the other hand, Calle Santiago is the main pedestrian street in the city centre, being Claudio Moyano the only road crossing it. This means this particular crossing supports daily a huge amount of people. Taking pedestrian flow into account to adapt traffic lights in real time is crucial to improve pedestrian’s mobility and safety in the crossing.
This new smart system counts all passersby, determining how many people are waiting to cross, and it sends all the information to the traffic lights control to adapt the green phase accordingly if there are too many pedestrians on the waiting areas.
And what is the difference with the traditional push-buttons? Well, this system provides two main advantages over the old-fashioned buttons. Firstly, it does not depend on users to be activated. Sometimes people are oblivious to the need of pushing the button in order to activate the pedestrian green phase on some crossings, while others are impaired and unable to push it, leaving the most vulnerable road users aside. Secondly, this system allows resuming traffic flow if pedestrians are no longer waiting to cross. Haven’t you ever been retained needlessly in some traffic lights just because someone pushed the button and then left?
In addition and in order to increase pedestrian safety even more, a smart lighting module has been also implemented to illuminate pedestrians on the zebra crossing, providing an enhanced visibility so that drivers can perceive pedestrians better and react accordingly.
After all these months of hard work, here is the system installed:

As one of the last activities carried out within the WASIS FP7 Project, Cidaut performed the vibro-acoustic characterisation of two components, firstly one test panel and secondly the largest fuselage section (1m diameter prototype). In both cases the study covered low and high frequency ranges. The aim of this activity was to validate FEM/BEM models for low frequency range and SEA models for high frequency.
The panel dimensions correspond to the real scale size of the aircraft fuselage. The idea was to learn about the panel behaviour before addressing the 1:2 scale aircraft fuselage. Two test methods were used to identify the behaviour at low frequencies: inertance tests and experimental modal analysis. For the high frequencies the Transmission Loss and Radiation Factor were obtained. Trough these parameters coupling loss factors associated with each phenomenon can be derived.
To characterize the barrel, two different tests have been designed aiming to reproduce the noise field and acoustic loads the fuselage section would be exposed to in real conditions. In these tests the transmitted energies between different parts of the specimen are measured. Besides, the Transmission Loss and radiation factor were obtained.
To complete this task, vibro-acoustic models of filament winding structures were developed. The results of these models have been correlated with the results of structure characterization. Once the validation of both models was finished, a new model of a full scale filament winding fuselage was carried out.
All these models have helped characterize the vibro acoustic performance of Wasis Composite Prototypes, enabling the project Consortium to assess not only the mechanical performance, but also other factors such as the transmission loss and radiation factor.

Stiffened panels are required in structures which can be obtained by different processes. They can be made by attaching stiffeners to a thin panel or by producing integrally stiffened panels. An innovating manufacturing process based on Liquid Resin Infusion (LRI) can be employed for obtaining integrally stiffened panels. It is based on moulding a dry NCF (Non Crimp Fabric) pre-form of Carbon fibre plies, which is bonded by a one-shot injection process to high stiffness, pre-cured pre-preg T-section stiffeners. This method presents benefits like lower costs in machining and fewer assembly operations.
The structural behaviour of integrally stiffened panels is normally better than those panels with attached stiffeners, but the difference is difficult to quantify by analysis, and is dependant on the manufacturing technology. Especially, the major interest is to clarify the structural behaviour of the panels, and more specifically their critical mode of failure.
The immediate solution could be to carry on comparative structural tests on different coupons moulded by different manufacturing methods, but it must be taken into account that habitually employed strain and stress measuring systems are limited to specific predefined points or have limited resolution. As the manufacturing process and materials are expensive, and last a long term, few coupons are available. Therefore, carefully combined measurement systems must be employed to obtain as much information as possible during the test, and also recurrent information is desirable to correlate results obtained by different sources.
As an answer to this scenario, the ACID project was launched to explore and analyze some of the previous factors, trying to study comparatively the mechanical properties and behaviours of different panels obtained by different manufacturing processes.
To achieve this goal, a testing matrix was accomplished, based on 3 LRI coupons. Two of them are panels with attached stiffeners and the other one is an integrally stiffened panel. It is expected that the results obtained in the tests help to clarify the panels’ behaviour and allow comparing the mechanical advantages versus economic benefits of the manufacturing processes.
The main objectives of the project were described as follows:
- Carry on large scale structural tests for obtaining ultimate properties and failure modes of components manufactured by different processes.
- Measure strain and stress information during the test in a recurrent manner to combine and correlate the obtained signals which define the structural behaviour of the panels throughout the test.
- Analyze the obtained results, establishing a comparison between the behaviours of panels with attached stiffeners and integrally stiffened panels.
- Analyze the obtained results, establishing a qualitative comparison between the mechanical advantages versus economic benefits of the manufacturing processes.
The main achievements of the project were the validation of the novel techniques for composite manufacturing due to the result obtained in the tests. The final mechanical response of the differently implemented panels shows great similarities in the main mechanical characteristics (failure load, stiffness, failure mode).
This validation serves as a starting point for further methodologies development and means a widening of the possible applications or fields of Composite materials.
At the same time, the cross comparison of the measurement devices is useful when deciding the most convenient measurement system for each project. The pros and cons are highlighted and an estimative error between systems is obtained.
The major environmental benefit is the validation of the novel cleaner manufacturing composite methodologies (less energy needed, less wastes, lower costs) against conventional procedures in representative playground.

In a few weeks, the nine partners of METALMORPHOSIS will meet to celebrate the forth Steering Committee Meeting. The overall aim of the project is to develop a new range of novel metal-composite hybrid products for the automotive industry, using the new and innovative electromagnetic pulse technology, which is highly suitable for joining dissimilar metal products. The current application range of this technology will be extended during the project towards joining of composite and metals. Mechanical joints like bolting or riveting are reliable and widely accepted, but they create local stress concentrations which reduce the strength of the components by as much as 50%, enough to eliminate the envisaged weight gains in many designs. Bonded joints are effective, but require very secure engineering, clean production environments and well-trained personnel to ensure reliable joints. Moreover, companies, and specially SMEs, lack the skills to design and produce reliable bonded structures.
Attending to this scenario, METALMORPHOSIS proposes the design of three automotive components: a shock absorber, a brake pedal and a bumper support. Research efforts have been applied to optimize all the parameters of the joining process combining experiments and simulation by finite elements methodology. The project has recently passed its midline and is evolving as expected.
One day before the meeting, the Exploitation Strategy Seminar will be celebrated at CIDAUT facilities. The working day will start with an ”ice breaking” session and will cover all the aspects and activities of exploitation from the state of the art to the intellectual property rights. The ESS will be driven by an expert and all the partners will attend: Belgium Welding Institute, Centimfe, Cidaut, Ideko, Poynting, Regeneracija, Stam, Tenneco and Toolpresse. The main aim of this Exploitation Strategy Seminar is to have an expert evaluating the list of exploitable results and assessing the partners on the best possible strategies to exploit them, solving the possible ownership and conflicts that arise in the process.

On December 5th, the final workshop of the Cenit TARGET project was held at AIRBUS premises in Getafe (Madrid). This research project, focused on smart and environmentally sustainable technologies for the production of structures made of composite materials, has been founded by the CDTI (Centro de Desarrollo Tecnológico Industrial), organism depending of the Spanish Ministry of Economy and Competitiveness.
Airbus facilities in Getafe (Madrid)
The event highlighted the main achievements reached by the 12 partner companies: Airbus Operations, Acciona Infraestructuras, Aernnova, Applus, Aciturri, Airbus Defence & Space, Hexel, Idec, MTorres, Sairem Ibérica, Tecnatom y TR Composites, along with 24 research organizations (Universities and Technology Centres).
Among them, CIDAUT has worked jointly with Aciturri in research activities to promote the development of advanced liquid composite moulding processes, seeking to reduce cycle times, energy consumption, scrap material and manufacturing costs associated to the production of structural components in Aeronautics, while improving product quality and increasing process robustness and repetitiveness. Processes that, if automated, would allow the effective production of complex structural components and the optimization of structures assembly.
The TARGET project, which commenced in 2010 with a 30 million Euros budget, was divided in nine work packages with the objective of researching and developing new smart and environmentally sustainable technologies for the production of composite structures. In particular, the research activities are focused on materials and processes that avoid using large autoclaves, and on functions integration; laying ground for new equipment and automation concepts that should lead to major cost savings.
TARGET main outcomes that deserve mention are: the development of advanced compaction and curing technologies of thermoset and thermoplastic materials out of autoclave; nanomaterials processing for their optimized integration in aeronautic laminates; the research in advanced resin infusion technologies and 3D carbon fabrics optimization; the development of new non-destructive inspecting techniques prior to curing; and the definition of integrated production systems, both in situ and in line, for the efficient manufacturing of composite components and structures.

The first review meeting of Free-Moby project was held last December in Brussels. Free-Moby is a three years FP7 founded project focused on the implementation of easy to deploy micro fully electrical vehicles and city EVs.
Figure 1: Schedule of the Vehicle to Home (V2H) connection and communication to optimize the performance of the harvested energy.
All the partners involved in the activities developed during the first twelve months of the project were present in the meeting. Cidaut presented the results of the “Preliminary market study for premium vehicles”, where the new trends in the demands of the consumer for the electric vehicles have been analyzed. The evolution of the characteristics of premium vehicles has been studied, how the comfort and the reliability have given the leading role to the passive and active safety and how nowadays the entertainment and the information are growing in importance for the new customers. Most of the premium characteristics are related to the connection of the vehicle so a deep analysis of the way this connection works has been made.
Cidaut also presented the results on the evolution of the smart charging technology. Free-Moby promotes the integration of renewable energies in electromobility through the installation of photovoltaic panels at home and on the vehicle. One of the targets of the project is to optimize the performance of the harvested energy. The solution found in Free-Moby project consists on the combination of DC-DC charging and a partial swapping. The innovation introduced in the case of the DC-DC conductive charging is to use a compact high performance charger outside the vehicle. This solution is possible thanks to the development of a high efficient rack compatible for vehicle and home use. This rack is composed by four battery modules that can be easily removed for partial swapping allowing a high degree of interaction between home and vehicle. The batteries charged at home with solar energy can be used for electromobility applications and the vehicle can be plug to the home in emergency cases. In order to achieve this integration, the empowerment of the communication has been highlighted as crucial. During first year important research has been made on communication inside the vehicle and also on vehicle to everything.

The project HYACINTH of the Fuel Cells and Hydrogen Joint Undertaking was launched last September. The project is coordinated by CENTRO NACIONAL DE EXPERIMENTACIONDE TECNOLOGIAS DE HIDROGENO Y PILAS DE COMBUSTIBLE. Other partners are I PLUS F FRANCE SARL, CENTRO DE INVESTIGACIONES ENERGETICAS, MEDIOAMBIENTALES Y TECNOLOGICAS-CIEMAT, RAZVOJNI CENTER ZA VODIKOVE TEHNOLOGIJE, ODC Services GMBH, ABERDEEN CITY COUNCIL. CIDAUT will also be involved as WP leader in order to determine the context influence over the stakeholders and to design the methodology to carry out the Social acceptance study.
The social acceptance by the general public, the stakeholders and the potential customers of Fuel Cell and Hydrogen (FCH) projects and applications across Europe is widely recognized as a key dimension in the sustainable implementation of FCH technologies. The document Fuel Cell and Hydrogen technologies in Europe: Financial and technology outlook on the European sector ambition 2014- 2020 by The New Energy World Industry Grouping (NEW-IG) considers the development of a good understanding of the conditions of societal acceptance as an essential element to support the establishment of these conditions in Europe. If hydrogen and fuel cell technologies are to play a significant role in Europe’s new energy and transport systems, a careful consideration of social acceptance issues is needed.
There is increasing realisation amongst policy makers and industry that public acceptance is a key consideration for any attempts to deploy and extend hydrogen technologies and infrastructures in Europe (EC, 2006). The development of hydrogen technologies in Europe will involve small-scale applications as well as large-scale infrastructures that may be influenced by the acceptance of the general public, stakeholders groups, the local community and the potential customers and users. Previous research on social acceptance has investigated the general levels of public understanding of FCH technologies in specific countries, but there is limited systematic evidence on the social acceptance of FCH technologies throughout Europe. The overall purpose of HYACINTH is to gain a deeper understanding of the social acceptance of hydrogen technologies across Europe as well as to develop a communication and management toolbox to be used in ongoing and future activities aiming at introducing hydrogen into mobility, stationary and energy or backup power supply systems.
Social acceptance of FCH technologies will be investigated via survey research with representative panels across Europe (up to 10.000 European citizens) and semi-structured interviews with 650 selected stakeholders in 10 countries. The design of the data gathering instruments will build upon the methodological and conceptual developments in the research of social acceptance of new technologies. The toolbox will provide the necessary background information and understanding of the current state of awareness and acceptance of FCH technologies by the general public and by stakeholder groups (industry, municipalities, researchers, fleet operators …). It will further provide the necessary tools to understand and manage expectations of future FCH projects and products in the transition phase, to identify regional challenges to the projects and to determine effective policy support measures.
Together the results from the research on the social acceptance of FCH technologies across Europe and the toolbox will support future projects to considerate the acceptance processes influenced by their activities; i.e. identifying regions of supportive acceptance, bottlenecks and challenges to be tackled, communication strategies and other means to actively manage the acceptance process FCH technologies.
