Composite Building Materials: Thermal and Mechanical Performances of Samples Realized with Hay and Natural Resins
2017
Unidad de excelencia María de Maeztu MdM-2015-0552 Recent years have seen an increasing public interest in issues related to energy saving and environmental pollution reduction in the building sector. As a result, many directives have been issued, the most important being the Directive 2010/31/EU (EPBD Recast) on the energy performance of buildings, which requires that "Member States shall ensure that by 31 December 2020 all new buildings are nearly zero-energy buildings". This goal can be obtained not only by reducing energy demand for heating and cooling, but also, for example, by improving building envelope performances. In this work, a first analysis of the thermal and structural behavi…
Rolling resistance contribution to a road pavement life cycle carbon footprint analysis
2016
Purpose Although the impact of road pavement surface condition on rolling resistance has been included in the life cycle assessment (LCA) framework of several studies in the last years, there is still a high level of uncertainty concerning the methodological assumptions and the parameters that can affect the results. In order to adopt pavement carbon footprint/LCA as a decision-making tool, it is necessary to explore the impact of the chosen methods and assumptions on the LCA results. Methods This paper provides a review of the main models describing the impact of the pavement surface properties on vehicle fuel consumption and analyses the influence of the methodological assumptions related…
CO2LD: An innovation educational project for High Degree Professional Training in Refrigeration
2013
EN] Refrigeration is one of the technology sectors that has sufered the most changes in the last twenty years, because of the negative impact of the fuids used in the refrigeration cycles, i.e., refrigerants, due to their impact on the ozone layer and their contribution to global warming. As a result of their negative efects, the European Union has established several directives to restrict the use of refrigerant fuids, and the sector therefore needs to adapt to the new regulations. This process of adaptation of the refrigeration sector to the new regulations must be carried out by all the agents involved, including those engaged in the training and education of the future refrigeration tec…
Fundamental period of infilled reinforced concrete frame structures
2016
AbstractThe fundamental period of vibration appears to be one of the most critical parameters for the seismic design and assessment of structures. In the present paper, the results of a large-scale analytical investigation on the parameters that affect the fundamental period of reinforced concrete structures are presented. The influence of the number of storeys, the number of spans, the span length, the infill wall panel stiffness and the percentage of openings within the infill panel on the fundamental period of infilled RC frames was investigated. Based on these results, a regression analysis is applied in order to propose a new empirical equation for the estimation of the fundamental per…
The interaction between personal and situational factors in developing future engineers’ creativity
2017
The purpose of this paper is to analyze the interaction between the technological and the social field. Growth and development require a continuous source of ideas. Their manufacture is efficient only by stimulating the creativity development in the knowledge economy. This essential skill will lead to making smart products and technologies improvements. This will also be the result of the interactions between the new IT-cloud technologies and other various factors, such as: knowledge, skills, approaches, attention, motivation and intellectual property.
Benchmarking in Romanian industrial environment
2017
Benchmarking is a managerial tool that can assist the organizational change and the innovation. The paper aims to discover the degree in which Romanian managers in various industrial fields use this modern tool in the improvement of business strategy or organizational processes. In this context, we presented some results of a selective research made in Romanian industrial environment. The respondents were experts in creativity management and benchmarking, acting in big, medium or small enterprises. They offered many solutions for increase the rate of use of benchmarking and creativity couple in the management of Romanian organizations.
Benefits of entrepreneurship education and training for engineering students
2017
In the present economic situation, having knowledge of an academic subject is no longer sufficient for a new graduate. Students are increasingly required to have skills and abilities which will increase their employability, such as: the retrieval and handling of information; communication and presentation; planning and problem solving; and social development and interaction. Entrepreneurial education and training provides individuals with the ability to recognize commercial opportunities, self‐esteem, knowledge and skills to act on them. It includes instruction in opportunity recognition, commercializing a concept, managing resources, and initiating a business venture. It also includes inst…
General aspects regarding the kinematic and dynamic analysis of the fabric take up/cloth roller
2017
The aim of this paper is to presents different aspects regarding the kinematic and dynamic behaviour of the fabric winding at the weaving loom. In this paper shall be presented the kinematic diagram for operating the cloth roll on the weaving machine, making the study of kinematic and dynamic cloth behaviour, setting up the expression of fabric tension. Finally, where drawn the charts of the variation of the fabric load depending by kinematic and constructive parameters.
Workforce active ageing case study in a Romanian manufacturing company
2017
Ageing workforce is a major trend that characterizes the demographic evolution of Europe, which generally affects the society, but also the organizations from economic and social point of view. Employers should change their negative perceptions of ageing workforce, whereas the changes that occur along with ageing are unable to influence the efficiency of work, assuming that a suitable strategy implemented to prevent and manage potential problems. The paper includes European and national statistics on the issue, a case study analysing the workforce ageing management in a Romanian manufacturing company, which has succeeded in achieving the active ageing target, and - on this basis - several g…
Improvement of learning quality in manufacturing technology: a case study
2017
The paper presents the initial part of a study designed to understand the place of the present generation of engineering students in the global picture of their working life. The education represents an inestimable good that accompanies peoples through their existence. Higher education is the place were teenagers with different profiles modelled by their families, studies; experiences and so on come to meet, in most cases, the final education platform before employment. In light of this the higher education has the major role of prepare the students with the knowledge and skills appropriate to the labour market. That means with the knowledge and skills they need and their future employers a…
