An Innovative Measurement Approach for Load Flow Analysis in MV Smart Grids
2016
This paper proposes a novel measurement procedure for load flow analysis in medium voltage (MV) smart grids. The new approach is based on power measurements at low voltage (LV) side of MV/LV distribution substations. Such measurements are carried out by means of power quality analyzers. If compared with the load flow methods based on measurements at the MV side, the proposed approach has a lower cost and it offers an equally reliable measurement system. The proposed algorithm takes the basic concept of the current summation backward/forward method; some modifications are introduced to use LV load powers measurements. To this aim, the MV/LV power transformer is properly modeled and taken int…
You cannot speak and listen at the same time: a probabilistic model of turn-taking.
2017
Turn-taking is a preverbal skill whose mastering constitutes an important precondition for many social interactions and joint actions. However, the cognitive mechanisms supporting turn-taking abilities are still poorly understood. Here, we propose a computational analysis of turn-taking in terms of two general mechanisms supporting joint actions: action prediction (e.g., recognizing the interlocutor's message and predicting the end of turn) and signaling (e.g., modifying one's own speech to make it more predictable and discriminable). We test the hypothesis that in a simulated conversational scenario dyads using these two mechanisms can recognize the utterances of their co-actors faster, wh…
MORPHODYNAMIC PROCESSES DOWNSTREAM OF MAN-MADE STRUCTURAL INTERVENTIONS: experimental investigation of the role of turbulent flow structures in the p…
2012
Abstract Experimental program was conducted to analyze scour – caused by a horizontal jet downstream of a rigid bed – and the flow velocity and turbulence characteristics within the scour hole. The experimental program was motivated by the fact that the knowledge of flow field, including turbulent characteristics, is fundamental to correctly simulate the bed-load transport and the temporal evolution of the scour hole and, thus, to define protective measures of scouring. In this paper some results of experiments – carried out to understand the role of flow turbulence in the prediction of scouring process and sediment movement – are reported. The analysis is conducted on the basis of detailed…
The links between smart specialisation strategy, the quintuple helix model and living labs
2018
This paper analyzes how the Living Labs can be designed as tools for a more effective implementation of the Smart Specialisation Strategy (S3) within the Quintuple Helix Model. Above all, the Quintuple Helix espouses the formation of a constructive situation encompassing ecology, knowledge and innovation, and creating extensive synergy between economy, society, and democracy. In this paper, we shall be focusing on the Quintuple Helix and Living Labs geared towards creating a shared arena in which services, processes and new ways of working via technology can be developed and tested with user representatives and researchers. Since the Living Lab is a rather new research area, the number of s…
New Forms of Work in the Light of Globalization in Software Development
2009
Globalization in software development introduced significant changes in the way organizations operate today. Software is nowadays produced by team members from geographically, temporally and culturally remote sites. Organizations seek for benefits that global market offers and face new challenges. Naturally resistant to change, these organizations often do not realize necessity for tailoring existing methods for distributed collaboration. Our empirical investigation shows a great variety in the ways organizations distribute responsibilities across remote sites and conclude that these can be divided into two main categories: joint collaboration that requires investments in team building and …
Innovation in collaborative design: an exploratory study in hackathon
2021
International audience; Collaborative design is the use of design practices which tend to favor the integration of different experts, and to support creativity and innovation. Therefore, in this study, we were particularly interested in the collaborative design tools used in the specific context of a pedagogical hackathon. During this event, 1310 engineering students mentored by professors and industrial experts worked on around 131 industrial projects. In this article, we will present our study of the tools put in place by the participants of these innovative projects according to their training. Our study is based on a collection of project data. We will show that storyboards are often us…
Case study: developing campus spaces through co-creation
2016
ABSTRACTHigher education institutions are designed to support their core processes – learning, teaching, research, and societal impact. In order for university facilities to support these activities, it is crucial to determine together with the users what these activities are and how they are supposed to be developed in the future. This article examines the relationship between user needs and the service level in construction projects through a case study where a university cafeteria was renovated using a participatory design (PD) method called charrette. The aim of this case study was to study the effects of collaborative ways of working when applied to a space retrofit project, and how th…
Evaluation of the laboratory prediction of surface properties of bituminous mixtures
2009
Abstract An experimental and analytical investigation was carried out both in laboratory and in situ on wearing courses. The approach presented in this paper aims to predict the in situ density and surface properties of bituminous layers, during the phase of mix design in laboratory. Therefore, the main attempt of this study is to identify, amongst the commonly available laboratory equipments, the most adequate for producing specimens that, used for carrying out simple and reliable laboratory test, allow the prediction of the surface characteristics of the mixture as laid on site. This is done by comparing the data collected from an experimental site with those calculated from laboratory sp…
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…
Remote programming of network robots within the UJI Industrial Robotics Telelaboratory: FPGA vision and SNRP network protocol
2009
This paper presents the UJI Industrial Robotics Telelaboratory, which lets Ph.D. and Master’s degree students perform robotics and computer vision tele-experiments. By using this system, students are able to program experiments remotely via the Web, in order to combine the use of a field-programmable gate array (FPGA) to provide real-time vision processing, a conveyor belt, and a Motoman industrial manipulator. This paper introduces the novel SNRP protocol (i.e., Simple Network Robot Protocol), which permits the integration of network robots and sensors within an e-learning platform in a simple and reliable manner. As long as the students are able to interact remotely with a real robotic sc…
