Industrial Microreactor Process Development up to Production
2008
This chapter is about industrial applications of microprocess technology. Industry is not very active in publishing not only because of confidentiality reasons but also because of the absence of direct need for a corresponding profile. Thus, one cannot expect that the ongoing developments can be shown with a similar degree of completeness, clarity and detailedness, as this is possible for reviewing scientific contributions from academy with a wealth of peer-reviewed papers. Especially, the information of major interest of what has been transferred to production and how do the companies make profit with the new technology is usually kept secret. Thus, it has to be accepted that some informat…
Establishing On-Line Corporate Training in Distributed, Synchronous eCollaboration: A Field Study
2010
Whereas technologies for eCollaboration are maturing, a need for learning eCollaboration in distributed organizations continues. This paper presents the experiences from establishing corporate training in distributed, synchronous eCollaboration. The training package was delivered solely on-line with synchronous interaction among the participants and the instructors. The study contributes to the scarce body of research on computer-supported collaborative learning in professional and corporate contexts. The reported experiences illustrate several challenges to establish corporate on-line training of eCollaboration: promotion of awareness of the benefits of learning eCollaboration, management …
Strengthening of steel-reinforced concrete structural elements by externally bonded FRP sheets and evaluation of their load carrying capacity
2014
Abstract The paper proposes a preliminary design tool for reinforced concrete (RC) elements strengthened by fiber-reinforced-polymer (FRP) sheets to be used in civil engineering applications and in particular in medical buildings. The design strategy is based on limit analysis theory and utilizes a numerical procedure which provides a direct method to determine peak load, failure mode and critical zones of the structural elements of interest.
The Effectiveness of Compliance Management Systems – An Experimental Approach
2014
Abstract This paper presents the results of an experimental approach to further strengthen activity in the area of Compliance Management Systems (CMS). It highlights the use of CMS in order to conduct business through persons which are ethically sensitized. Possible cause-effect relations are tested and evaluated. The paper highlights that not all applied measures do have a positive impact on decisions which have to be taken in ethical dilemma situations. The effectiveness of CMS depends on a careful selection of the right activities. Nevertheless elements could be identified which are likely to have a stronger impact on the decision making than others. These should be in the focus when des…
Agrigento Cathedral
2015
At present Agrigento Cathedral is affected by extensive damage that seems to be mainly due to partial slumping of the foundation soil. The chapter deals with the state of damage that affects the cathedral and the investigation carried out for the mechanical characterization of the construction, the formulation of an FE model and the assessment of the safety level with respect to the service loads and with respect to exceptional loads like seismic ones. In the chapter the details of the above investigation are discussed, consideration also being given to the monitoring carried out in order to understand whether the phenomenon affecting the cathedral is ongoing. The results of the monitoring …
Design, sizing and set up of a specific low cost electronic load for PV modules characterization
2013
In this paper, the design, sizing and set-up of a specific low cost electronic load, based on a DC-DC step-down converter, suitable for the PV module I - V characteristic curves determination, is described. In particular, for its set up, a low cost and user friendly micro-controller has been employed in order to generate the PWM signal. The measures carried out connecting the electronic load prototype to a commercial PV module are here presented and discussed. The conceived electronic load has allowed the determination of 80% of the PV module characteristic curves in 2 s. This low measurement time, lower than the time intervals in which weather conditions may change, allows to assume as con…
Modeling of a Smart Grid System Using Real Time Data οn Neplan
2013
The Institute for Energy and Transport (IET) is one of the seven institutes of the Joint Research Centre, which is a Directorate-General of the European Commission. IET is based both in Petten, the Netherlands, and Ispra, Italy, and has a multidisciplinary team of around three hundred academic, technical and support staff members. The mission of IET is to provide support to European Union policies in order to ensure sustainable, safe, secure and efficient energy production, distribution and use. The Energy Security Unit (ESU) is part of IET based in Petten and Ispra. A research action set up within this unit is devoted to studies on smart electricity systems (SES) and operates a Smart Grids…
Definition of a laboratory optimization protocol for road bitumen improved with recycled tire rubber
2012
Abstract Bearing in mind the need to answer one of the most frequent needs for civil construction, in general, and major project such as road infrastructures in particular, this paper presents the results of a laboratory experimental study in order to evaluate the performance improvement that is possible to achieve when modifying road bitumen with CRM (Crumb Rubber Modifier) from discarded tire rubber (TR), using a Wet Process. The environmental advantage is double, since the aim of the research is to obtain high performance road bitumen thanks to the re-use of a discarded material, such as the rubber tires, which otherwise would be dumped in scrap-yard. In particular, this experimental stu…
The Role of Social and Collaborative Networks in the Development of in-House Multimedia Language Learning Materials
2012
The development of in-house language learning materials has being going on for many decades. In the past, it was difficult for language teachers worldwide to share their in-house materials with other teachers, and so was having access to the materials developed by others. This often produced a feeling of isolation and, very frequently, provoked a duplication of efforts and a bigger investment of time. However, thanks to the Web 2.0 teachers and practitioners worldwide can communicate with each other and share experiences and materials. While this aspect of the so-called Social Web has being successfully exploded in the past few decades, especially in the case of online communities of teache…
Wind turbine modeling using the bond graph
2011
Author's version of a chapter in the book: Proceedings of the IEEE International Symposium on Computer-Aided Control System Design. Also available from the publisher at: http://dx.doi.org/10.1109/CACSD.2011.6044572 This paper addresses the problem of bond graph methodology as a graphical approach for modeling wind turbine systems. In this case, we consider the modeling of a wind turbine system with individual pitch control scheme and the interaction with tower motions. Two different bond graph models are presented, one complex and one simplified. Furthermore, the purpose of this paper is not to validate a specific wind turbine model, but rather show the difference between modeling with a cl…
