The Development of the Teachers’ Competences and Abilities Concerning the Educational Mentoring of the Disabled
2015
Abstract In this paper, we will present some important aspects regarding the design and implementation of a project which generates significant results in the life-long learning of the teachers from all levels of the Romanian education system. The project is part of the priority axis: “The development of human resources in education and professional training”. The general objective aims to improve the e-learning interactive methods and the activity with the disabled in order to use them also within the didactic activity, to improve the results of the educational process as well as to increase the disabled access to education.
Health Education at La Ribera Universitary Hospital
2013
This paper describes the potential of learning platforms offering at the La Ribera Health Department. More than 100 activities have been designed and at least 5000 users have been participating. The paper concludes, first, that there are important factors to achieve a successful implementation of such elearning project. In second place it remarks that elearning platform can be used for other support activities rather than only online courses. Finally, the study emphasizes that training in electronic medical record of our professionals is a key element of hospital business.
Mathematical modelling of an inverter-based distributed generator
2016
In this paper, a modeling approach of a three phase power inverter based on an electrostatic synchronous machine is presented. By the proposed approach, any inverter-based distributed generator in a microgrid can be replaced by an equivalent electrostatic machine. This paper aims to promote the use of the proposed modeling approach in the analysis of microgrid stability. Thanks to the proposed modeling approach, transient performances of on-grid operation of converter-based distributed generators could be easily analyzed by multi-machine models. Parameters of the equivalent synchronous electrostatic machine model are derived to achieve equivalence with the inverter model. Small signal model…
An interpretive framework for assessing and monitoring the sustainability of school gardens
2016
School gardens are, increasingly, an integral part of projects aiming to promote nutritional education and environmental sustainability in many countries throughout the world. In the late 1950s, FAO (Food and Agriculture Organization) and UNICEF (United Nations Children's Fund) had already developed projects to improve the dietary intake and behavior through school and community gardens. However, notwithstanding decades of experience, real proof of how these programs contribute to improving sustainability has not been well-documented, and reported findings have mostly been anecdotal. Therefore, it is important to begin a process of collecting and monitoring data to quantify the results and …
Evaluating the Sustainability in Complex Agri-Food Systems: The SAEMETH Framework
2015
During the last few years, the definition of sustainability and the translation of its general principles into practical and operative tasks have come into the foreground of scientific research and political agendas throughout the world. The understanding and the evaluation of the environmental, social and economic performances of complex agricultural food systems is probably the real challenge, and the design of more sustainable alternatives has been recognized as necessary for a correct territorial management. This study’s primary goal is the proposition of an interpretive structure “Sustainable Agri-Food Evaluation Methodology” (SAEMETH), able to guide the evaluation of the sustainabilit…
Morally Successful Collaboration between Academia and Industry — A Case of a Project Course
2006
Academia-industry collaboration is common in the IT-field, and it includes training programs, research centre activities, and industry advisory boards (Watson and Huber 2000). For the industry, co-operation provides possibilities to acquire human resources and, for the academia, co-operation ensures that research and teaching activities are relevant. Regardless of its popularity little is known about moral issues relating to this phenomenon. This study intends to fill the gap in knowledge by determining the nature of moral conflicts perceived by clients, students, and instructors of a collaborative project course, and by formulating a framework to successfully getting grips with these confl…
Achieving maximum power transfer in a multi-source renewable system
2014
In this paper, a multi-source DC-DC power system is proposed for renewable applications. A multi-input, single inductor power converter controlled by two interacting control loops is designed. The steady-state and small-signal analysis of the designed system is carried out. A battery-photovoltaic system is designed as an application example. Both the output voltage and maximum power point of solar panels are properly controlled to achieve high performances of the whole system. Experimental results on a 48 V laboratory prototype are presented to discuss system performances.
Table Top Augmented Reality System for Conceptual Design and Prototyping
2011
The AugmenTable is a desktop augmented reality workstation intended for conceptual design and prototyping. It combines a thin form factor display, inexpensive web cameras, and a PC into a unique system that enables natural interaction with virtual and physical parts. This initial implementation of the AugmenTable takes advantage of the popular open source augmented reality software platform ARToolkit to enable manual interaction with physical parts, as well as interaction with virtual parts via a physically marked pointer or a color-marked fingertip. This paper describes similar previous work, the methods used to create the AugmenTable, the novel interaction it affords users, and a number o…
Design and control of a novel multi-source renewable energy system
2014
In this paper, a novel multi-input, single-inductor architecture is proposed. An innovative hysteretic control strategy of both the output voltage and the sources operating point control is designed and tested. Benefits brought by the proposed architecture over existing solutions are widely investigated. As an example, the design of a 48 V dual input system which is fed by photovoltaic and thermo-electric generators is proposed. Design guidelines are given and simulation results are presented to test the efficiency of the proposed architecture.
Assessment of methodologies and data used to calculate desalination costs
2017
Abstract In desalination, similarly with other industries, the cost of the final product is one of the most important criteria that define the commercial success of a specific technology. Therefore, when new projects are planned or new technologies are proposed, the analysis of the expected costs attracts a lot of attention and is compared to (perceived) costs of state-of-the-art desalination or costs of alternative fresh water supply options. This comparison only makes sense if the cost assessment methodologies are based on the same principles and use common assumptions. This paper assesses: (i) the methodologies used to calculate the water cost; (ii) the boundary conditions and (iii) the …
