This volume entitled "TRANSAERO - A European Initiative on Transient Aerodynamics for Railway System Optimisation" contains the results of the contributors during the project th symposium which took place in Paris, France, on 4th and 5 May 1999 hosted by the International Union of Railways, UIC. This symposium was organised within the framework of the BRITE/EURAM project "TRANSAERO" under contract BRPR-CT9S-0067. The project has been co-financed by the European Union within the Fourth Research Framework Programme. More than 100 participants followed the invitation to the symposium. This great response shows the continuing interest in a relevant topic of railway technology and offered us the opportunity to present the recent results of intense European collaboration to the international community of railway aerodynamic experts. In the last few decades, mobility in Europe, based on automobiles for individual traffic and lorries for freight traffic, has grown more and more; yearly growth rates of more than 10% have often been reported by statistics. Even with a fully developed construction programme for motorways and similar high-performance roads, these growth rates cumulated over the years cannot easily be handled in an environment-friendly way. The European Commission has therefore given distinct political signals to get more passengers onto the railways. This policy represents a clear challenge for the next few decades for European railway companies: the considerable increase in mobility in a Europe with falling borders will cause a doubling of the traffic volume within the next 10 to 20 years.

The Spanish Association of Project Engineering is pleased to publish the following selection of the best papers presented at the 13th International Congress on Project Engineering. After having organized an annual Congress with an array of universities over the last 16 years —first at the national and then at the international level— by the end of 2008 the AEIPRO Directive Board decided to establish a Scientific Committee to evaluate the papers presented at the Congress. The Scientific Committee has also chosen the works to be published in the selected proceedings of the Congress. The procedures to establish the Scientific Committee and evaluate the submitted papers are explained below in detail. It is the hope of the Committee that the compiled works contribute to the improvement of project engineering research and improve the transfer of results to the job of Project Engineers.
The oil and gas industry continues to increase its practical applications for multiphase technology as it matures and becomes more accepted. In particular, the economic benefits for developing marginal and deep water oil fields using multiphase techniques are now established. Current oil price levels and the need to develop these fields will drive the application of multiphase technology even further forward.
This book is the fifth volume of the proceedings of the 4th GeoShanghai International Conference that was held on May 27 - 30, 2018. This volume, entitled “Tunneling and Underground Construction”, covers the recent advances and technologies in tunneling and underground structure engineering. It presents the state-of-the-art planning philosophy, theories, experiments, methodologies and findings in the related areas. The importance of underground space utilization to the development of human society is also addressed. The challenges and future directions of underground engineering are highlighted. The topics include but are not limited to the tunneling and underground construction induced ground deformation, mechanical behaviors of segmental lining systems, tunneling in challenging situations, maintenance tactic and emergency counter-measures. The book may benefit researchers and scientists from the academic fields of tunneling and underground structure engineering as well as practical engineers from the industry. Each of the papers included in this book received at least two positive peer reviews. The editors would like to express their sincerest appreciation to all of the anonymous reviewers all over the world, for their diligent work.
