Discrete element modelling of rock cutting processes interaction with evaluation of tool wear

The document presents a numerical model of rocks and soils using spherical Discrete Elements, also called Distinct Elements. The motion of spherical elements is described by means of equations of rigid body dynamics. Explicit integration in time yields high computational efficiency. Spherical elements interact among one another with contact forces, both in normal and tangential directions. Efficient contact search scheme based on the octree structures has been implemented. Special constitutive model of contact interface taking into account cohesion forces allows us to model fracture and decohesion of materials. Numerical simulation predicts wear of rock cutting tools. The developed numerical algorithm of wear evaluation allows us us to predict evolution of the shape of the tool caused by wear. Results of numerical simulation are validated by comparison with experimental data.

Renewable gases. An emerging energy vector

  • Feliu Jofre, Álvaro
  • Flotats Ripoll, Xavier
The European Union has set itself very ambitious goals for the year 2030 in its contribution to the fight against climate change; in addition, it is proposing a strategy for 2050 that leads to the almost complete decarbonisation of the economy. At the same time, it is searching for a way to achieve its objectives that is cost efficient and sustainable from the point of view of competitiveness and of the generation of jobs. With these aims, and given the difficulty of fulfilling them only through electrification, we find interest in renewable gases emerging once more. Whether biomethane, syngas or hydrogen, they are seen as an indispensable vector that is complementary to electricity, and have the added virtue of being able to use existing infrastructures to a great extent. This avoids costly and unpopular new facilities, as well as contributing to the processes of the circular economy through the management of certain types of waste, which is becoming more and more complicated to deal with. In this book, authors identify and describe in detail the existing technologies for the generation of renewable gases and for attaining from them a quality that can be equated to that of natural gas or the conditions in which mixing them is possible. They also assess the different possible uses of renewable gases and the most suitable distribution pathways. In short, the work evaluates both the potential of renewable gases in Spain and their economic viability, as well as comparing Spanish regulations with those in other EU countries. From all this, some proposals emerge to improve the development of renewable gases in Spain based on the experience of other countries that are more advanced in this field. The book confirms that renewable gases have important developmental potential in Spain, and that they can contribute significantly to the reduction of greenhouse gas emissions and to waste management. There is undoubtedly still a long way to go in terms of technological development and reducing costs, but the potential exists and must be evaluated as a contribution to the objectives of the fight against climate change. This book aims to assist in that assessment.

After the project : updating mass housing estates = actualització de polígons residencials

  • Brossa, Marc
  • Sotoca García, Adolfo
Descripció del recurs: 19 de novembre de 2012, A la part inferior de la portada addicional: II EcoRehab, Text en anglès i castellà, It is often argued that the future city will be that one built on the already urbanized territory. This statement asks for a new approach to Urban Planning, more attentive to regenerating existing urban fabrics than extending them. Within this context, Mass Housing Estates and their renovation become an issue of great relevance. Being one of the 20th century's genuine forms of urban growth, their accelerated and very explicit obsolescence demands profound reflection on strategies and interventions. This book shows some descriptions, thoughts and tentative designs on this particular urban form. Opened to an international scope, most of the presented materials and writings are referred to Barcelona and its MHE, since it is an exceptional case study in this matter, as it is in many other fields related to urbanism. The large number and diversity of housing estates that were developed throughout the last century set the framework for the analysis of three challenges that MHE renewal will face in the future: guarantee of basic living conditions; urbanity provision and metropolitan integration. "The relevance of MHEs was the opportunity to build residential neighbourhoods with a much greater po-tential than traditional ones. Some specific cases have shown us how to design residential environments and others show us precisely the opposite, how not to. MHE shouldn't have been located in isolated sites with an excessive insistence on a certain type of architec-ture. Today the centre of our metropolitan reality continues to be Barcelona: it is a key element, extremely important. But let us look with a renewed attention at the metropolitan context. The baricentre of this metro-politan Barcelona is certainly not located in Ciutadella, but somewhere in Collserola. It is in this change of scale, it is in understanding the real city, that we will find the key to redefine MHE as an integral part of a much broader and more complex system than the former periphery where they were once built. Now we have the capacity and sufficient perspective to discern what was a mistake from the positive assets we can recover from these territories" Ferrer-Sotoca

Research into the area of supply chain

  • Corominas Subias, Albert
Prospective doctoral students or anybody who wishes to undertake research activities find often difficult to know what research is about, how the settings are where research takes place, and how results are presented and communicated. In addition, for people who want to make innovative contributions within an organization is important to tell apart research from what is not, and where to find the results. In the supply chain field, there are two additional difficulties. On the one hand, the lack of a generally accepted definition of supply chain. On the other, the fact that, alongside research publications, others proliferate that, although being rather informative, speculative or even falling in self-help literature field, are sometimes presented as if they were search results. The text is a tool to answer the questions implicit in the above considerations, in order to reduce the time elapsed between the moment the student decides to do research and when he or she starts to really do it, and thus contribute to improve productivity and quality of research.

RAILPAG: Railway Project Appraisal Guidelines

  • Turró Calvet, Mateu
The RAILPAG (Railway Project Appraisal Guidelines) aim at providing a common framework for the appraisal of railway projects across the EU. They are the result of a similar harmonisation exercise as that carried out under TINA (Transport Infrastructure Needs Assessment) for transport projects in general in the Accession countries in 1999. The TINA Guidelines were adopted by the UN-ECE1 in 2003. The guidelines have been prepared following an initiative of the European Investment Bank. The EIB has received financial support from the European Commission (DGTREN) and technical support from experts representing DGTREN, other international financial institutions (IFIs) and the key associations of the rail industry, integrated in a Steering Committee. This report has mainly been carried out by the services of the EIB and has benefitted from some background work carried out by CENIT, Center for Innovation in Transport of the Universitat Politècnica de Catalunya, Barcelona, Spain, and Dr. Nils Bruzelius. This report is intended to be the first step towards a comprehensive harmonised methodology for appraisal of rail investments in the EU and, eventually, in countries of the European Neighbourhood area. To further develop this framework, the EIB will continue to work closely with the European Commission, the other institutions that have participated in this exercise and other interested parties. EIB will maintain an internet site ( where updated versions of the Guidelines and new appraisal tools as well as other relevant documents, on-going research and comments will be posted. The objective is to achieve, in the medium term, a consensus on a harmonised detailed appraisal procedure that would be used by project promoters to present their projects to the European Commission and to the IFIs for funding and, eventually, by planning services of public administration, rail infrastructure managers, rail companies and their consultants as a continuously updated reference to guide their appraisal work.
