21 Oct Engineering Power – Vol. 12 (3) 2017

Croatian Academy of Engineering (HATZ)
2017
Vol. 12(3) 2017 - 20 pages - English Biomedical engineering is one of the fastest developing fields, which touches many specialties and provides a basis for the faster development of medical science. Close and fruitful cooperation of medical doctors and engineers results in team synergy, thus enabling faster progress than in the case when everyone works separately in their own “silos”. At the University of Zagreb, Faculty of Mechanical Engineering and Naval Architecture we recognized the necessity of such cooperation mora than ten years ago. Today, our several engineer teams are t5eamed up with medical doctors in projects related to medicine. As pathological conditions in the cardiovascular system (such as atherosclerosis, formation of aneurysms, valvular heart diseases, ect.) are strongly interlinked with the hemodynamics of the cardiovascular system and tissue remodelling, they attract of our departments. The Department of Fluid Mechanics is now in charge of hemodynamics and the Department of Mechanics is in charge of tissue remodelling and formation of aneurysms. The papers below provide the Department of Fluid Mechanics team with a short overview over research activities and results in the field of hemodynamic modelling of the cardiovascular system. we have developed models and numerical methods with different levels of complexity: from a lumped parameter model to one-dimensional and quasi two-dimensional model. The simplest lumped parameter model is important for clinicials, since it describes the principal part of the cardiovascular systems with a relatively small number of parameters, each having a clear physiological meaning crucial to understand the system function. Such a model is being applied in an ongoing project considering non-invasive method for the model parameter identification of pulmonary circulation in subjects with pulmonary hypertension. The problem with one-dimensional and three-dimensional models is that they require more input data (e.g. space variation of blood vessel diameter and wall properties) that cannot be easily measured, but still such models are very important for understanding wave phenomena in the arterial tree and for estimating the local flow parameters, important for the prediction of some diseases (such as aneurysm growth). The developed models and methods are a good basis for prospective cooperation with the University of Zagreb, School of Medicine with purpose of collaborative research on artificial heart development and education of prospective medical engineering students.

21 Oct Security Research – Opportunities and Perspectives

National Academy of Science and Engineering (acatech)
2009
Security is a basic need of human beings and therefore of society. Science and technology serve the purpose of satisfying this fundamental need. The concept of security is used, however, in many different ways; as a consequence, the heterogeneity of the concept is implemented in the models and solutions conceived to guarantee security and safety. The publication constitutes an initial discussion result of the topical network of “Security.” The contributions illustrate the complexity of the concept of “security” and the corresponding theories and solution approaches. All contributions are based on the assumption that the conceptual separation of “security” and “safety” has to be overcome. When developing new technologies, aspects of both safety and security have to be taken into consideration. While practical experience is seeking the integration of the most diverse protection goals, subsidy policy is still geared to separate approaches. The volume on hand sketches thought-provoking stimuli from various scientific disciplines, which could make a contribution to constituting a bridge between safety and security.

21 Oct Materials Science and Engineering in Germany

National Academy of Science and Engineering (acatech)
2009
Materials are the basis of the production industry. Traditionally, Germany has been very strongly positioned in this sector. Despite the great economic significance of classic materials and new materials, public awareness of materials is very low. Consequently, the corresponding degree programs are pursued by only a small number of students. To advance its overall goals, such as the promotion of young scientists and engineers and the application of research results to technology, acatech, which is the German Academy of Science and Engineering, works to strengthen materials science and engineering in Germany. Research is largely bound to the classic disciplines. As a result, gaps open in the material-to-product chain, which in turn lead to a delayed interdisciplinary transfer and ultimately to a delay in the application of materials in innovation. The paper on hand is the result of the analysis conducted by a project group as part of the topical network of materials science and engineering of acatech. The current situation of materials science and engineering in Germany is described and the need for action presented.

21 Oct About Robots

National Academy of Technologies of France (NATF)
2009
Man has always sought to free himself from inevitable, fastidious and boring work. Technological progress has partially satisfied his desires through two generic tools: the computer for mental tasks and the robot for physical labour. This report addresses questions about robots frequently raised by the public at large. People regularly hear about them but never actually see them. The main questions concern reasons for their absence, their intelligence and a comparison with human capacities. Since the future cannot be written in advance, where there are no guidelines, the author expresses his own assumptions.

21 Oct Yellow pages for innovators in Lombardy

CNR, INFN, ITT and Politecnico di Torino consortium
2010
The guide aims at a detailed mapping of  infrastructural actors of the research and innovation system in Lombardy region. Enterprises are in the center of the innovation process: they have the responsibility and the interest in converting the results of R&D activities in goods and services for the market, and of creating value through the production and commercialization of new products. But this is not enough, other institutions are indispensable in an advanced and effective innovation system. First of all universities and public research organizations which supply the necessary higher education to researchers, but also other structures and services are needed: normative, certification, patent offices,  ICT infrastructures, statistics, test and measurements centers, as well as technology transfer structures, incubators, science parks. And on other levels: financial institutions, as seed and venture capital organizations, with specialization in the creation of and support to high tech start up and spin off companies.

21 Oct Technological Knowledge – Evolution, Methods, Structures

National Academy of Science and Engineering (acatech)
2010
In its initial year as the German Academy of Science and Engineering, acatech made an essential contribution to the discussion about the formulation of the self-conception of the engineering sciences with the “Technological Knowledge” conference it organized. The interdisciplinary contributions focused on questions about the evolution, methods and structure of technological knowledge, i.e. questions about the continuation of the systematization of the engineering sciences. Against the backdrop of the discussion, the conference contributions reflect the principles according to methodology, scientific theory as well as the formal foundations of the engineering sciences.

21 Oct Technology, development and the SMEs

National Academy of Technologies of France (NATF)
2010
How to help the SMEs to take into account technology evolutions, with all their consequences and how to encourage them to play an even more important role in the innovation process? This report suggests a few elements of answers to these questions. In particular it insists on the necessity of a technical education and training of the highest quality. It advocates the technology education system to be profoundly renovated. It also invites to evaluate the present adequacy of the permanent training system to the needs of SMEs.
