Transdisciplinary niches fostering Lifelong Learning
2011
Abstract The purpose of this paper is to outline a new approach of lifelong learning in the light of transdisciplinarity niches. Considering the issues education is currently confronting, a way to find solutions to these problems could be transdisciplinary research, consisting in transdisciplinary niches. The paper continues some previous research made in “Lucian Blaga” University of Sibiu in order to adapt engineering education to lifelong learning. It also provides two examples of transdiciplinary niches presented in two doctoral theses, which are now developed by “EU 2020 research cluster” in the aforesaid university. Both theses require a transdisciplinary approach and involve fields fr…
Formwork application optimization by using augmented reality
2016
By using the PLM (Product Lifecycle Management) principle on the formwork case study, after determining the functions and the technical solutions, the application must be made as optimum as possible in order to assure productivity and provide the necessary information as quick as possible. The concept is to create a complex management for the formwork based on augmented reality. By taking into account the development rate of the information, augmented reality is tending to be one of the widest (in term of domain) visualization instrument. Also used in the construction domain, augmented reality can be applied also for the case of formwork design and management. The application of the solutio…
Development of an optical link card for the upgrade phase II of TileCal experiment
2010
This work presents the design of an optical link card developed in the frame of the R&D activities for the phase 2 upgrade of the TileCal experiment as part of the evaluation of different technologies for the final choice in the next two years. The board is designed as a mezzanine which can work independently or plugged in the Optical Multiplexer Board of the TileCal backend electronics. It includes two SNAP 12 optical connectors able to transmit and receive up to 75 Gbps and one SFP optical connector for lower speeds and compatibility with existing hardware as the Read Out Driver. All processing is done in a Stratix II GX FPGA. Details are given on the hardware design including signal and …
Tramway Track: A New Approach for Measuring the Transverse Profile of Worn-Out Rails
2012
Abstract Monitoring the wear condition of the tramway superstructure is one of the key points to guarantee an adequate safety level of the light rail transport system. The purpose of this paper is to suggest a new non-conventionalprocedure for measuring the transverse profile of rails in operation by means of image-processing technique. This methodological approach is based on the “information” contained in high-resolution photographic images of tracks and on specific algorithms which allow to obtain the exact geometric profile of the rails and therefore to measure the state of the rail-head extrados wear.
Magister : revista de formación del profesorado e investigación educativa
2016
La competencia colaborativa es una herramienta muy útil para el alumnado universitario. La diversidad de ámbitos profesionales que existen hoy en día demanda unos trabajadores competentes que se adapten a una realidad laboral compleja y cambiante. En este sentido, las relaciones interpersonales cobran gran importancia al requerir la colaboración entre profesionales para conseguir un objetivo final. El presente artículo describe una propuesta de trabajo colaborativo que se llevó a cabo con el alumnado universitario del cuarto curso de Magisterio de la Universitat de València que cursaban el itinerario de especialización en Educación Musical. Collaborative competition is a very useful tool fo…
The influence of rainfall time resolution for urban water quality modelling
2010
The objective of this paper is the definition of a methodology to evaluate the impact of the temporal resolution of rainfall measurements in urban drainage modelling applications. More specifically the effect of the temporal resolution on urban water quality modelling is detected analysing the uncertainty of the response of rainfall–runoff modelling. Analyses have been carried out using historical rainfall–discharge data collected for the Fossolo catchment (Bologna, Italy). According to the methodology, the historical rainfall data are taken as a reference, and resampled data have been obtained through a rescaling procedure with variable temporal windows. The shape comparison between ‘true’…
Stormwater infiltration trenches: a conceptual modelling approach.
2009
In recent years, limitations linked to traditional urban drainage schemes have been pointed out and new approaches are developing introducing more natural methods for retaining and/or disposing of stormwater. These mitigation measures are generally called Best Management Practices or Sustainable Urban Drainage System and they include practices such as infiltration and storage tanks in order to reduce the peak flow and retain part of the polluting components. The introduction of such practices in urban drainage systems entails an upgrade of existing modelling frameworks in order to evaluate their efficiency in mitigating the impact of urban drainage systems on receiving water bodies. While s…
Successful principalship in Norway: sustainable ethos and incremental changes?
2009
PurposeThe purpose of this paper is to explore whether and how success has been sustained over time in schools which were identified as being successful five years ago.Design/methodology/approachThree schools were selected for a revisit, and the sample included two combined schools (grade 1‐10) and one upper secondary school (grade 11‐13). In two schools the same principals were still in post, and in the third school there had recently been a change in principalship. Interviews with the principal and a group of teachers at each school were the major source of new data. Questions that guided the study: What structural and cultural changes can be identified within the schools compared with fi…
Effect of silica-type sol–gel carrier’s structure and morphology on a supported Ziegler–Natta catalyst for ethylene polymerization
2006
Abstract Silica xerogels with different structures and morphology, synthesized using a sol–gel procedure, were used as a carrier of vanadium catalysts (VOCl 3 /AlEt 2 Cl) for ethylene polymerization. Two techniques of catalyst synthesis were applied: slurry impregnation and gas-phase adsorption and the relevant polymerization methods were then employed. The effect of the carrier structure and morphology on the vanadium loading in the catalysts, the catalyst’s activity and kinetic stability were investigated.
Reactive melt blending of functionalized-MW/CNTs with polyolefin
2012
Adding nanotube adding into a polymeric matrix leads to the formulation of nanocomposites with enhanced macroscopical performances, and, moreover, the use of functionalized MW-CNTs leads to the nanocomposite formulation with even better properties. Furthermore, the reactive melt blending can be considered as a powerful processing method, i.e. reasonably simple and ecologically friendly, in order to formulate polymer based nanocomposite with good performance. In this work, the reactive melt blending between an ethylene-acrylic acid co-polymer, bis-oxazoline and functionalized MW-CNTs was performed and the rheological properties of the formulated systems were investigated.
