Influence of the channel design on the heat and mass exchange of induction channel furnace
2011
PurposeThe purpose of this paper is to present in‐depth numerical modelling of heat and mass exchange in industrial induction channel furnace (ICF).Design/methodology/approachThe turbulent heat and mass exchange in the melt is calculated using a three‐dimensional (3D) electromagnetic model and a 3D transient large eddy simulation method. The simulation model has been verified by flow velocity and temperature measurements, which were carried out using an industrial sized channel inductor operating with Wood's metal as a low temperature model melt.FindingsThe ICF is well‐established for melting, holding and casting in the metallurgical industry. But there are still open questions regarding th…
The Transverse Crack Tension test revisited
2016
Several problems arise when measuring the mode II interlaminar fracture toughness using a Transverse Crack Tension specimen; in particular, the fracture toughness depends on the geometry of the specimen and cannot be considered a material parameter. A preliminary experimental campaign was conducted on TCTs of different sizes but no fracture toughness was measured because the TCTs failed in an unacceptable way, invalidating the tests. A comprehensive numerical and experimental investigation is conducted to identify the main causes of this behaviour and a modification of the geometry of the specimen is proposed. It is believed that the obtained results represent a significant contribution in …
Use of ICT Teaching-Learning Methods make School Math Blossom
2012
Abstract Our society often talks that their kids at school are taught using old educational methods. It is boring for kids and they lose interest in learning. New generation of kids are different – more provocative, intuitive, sensitive, mental, in some cases more aggressive than previous generations. That is what parents and teachers now see. Therefore the aims of nowadays education demand to choose educational methods promoting active process of cognition that develop skills of learning, creative use of knowledge, skills of self-assessment, cooperation, indulgence to different points of view. Interactive educational methods help to realize those tasks and provide cooperation among teacher…
New Measurement Procedure for Load Flow Evaluation in Medium Voltage Smart Grids
2013
The aim of this paper is to present a new approach for the medium voltage (MV) distribution network load flow analysis, mainly based on power measurement at the low voltage (LV) level of MV/LV distribution substations. This allows to use measurement instruments, usually already installed in the secondary substations, thus achieving an equally reliable measurement system with a lower cost compared to measurements at the MV side. The new approach can be applied using a proper communication system to collect the nodal measurements and an iterative algorithm based on ladder iterative technique (LIT) to compute the load flow. The validity of this method is presented and discussed on the basis of…
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…
Management performance of telework teams based on experimental methods
2009
This paper seeks to answer the following two questions: Which management factors have great effect on the management performance of telework teams? and How should management choose suitable team members for telework? The research will use experimental methods for exploring the novel topic of management performance of telework teams. The experimental design, implementation and result analysis will be done by using a computer experimental system we developed. The experimental research results show that an effective way of improving management performance of telework teams relates to the positive and the negative degrees of psychological factors, team factors, ethical factors and individual ba…
Understanding flow experience from users’ requirements
2015
This paper argues that the concept of flow can be useful in gaining a better understanding of information system users’ flow experience. This paper applies this concept in the requirements development phase of an Internet protocol television e-learning service development project. The findings show that flow experience can be visualised and measured, and that there are differences in how users see and perceive different features. Some features are driven by more experiential needs, whereas others are driven by more task-oriented goals. The findings indicate that the users’ perceived flow experiences can already be measured during the early phases of information systems IS development projec…
Optimization methods for complex sheet metal stamping computer aided engineering
2010
Nowadays, sheet metal stamping processes design is not a trivial task due to the complex issues to be taken into account (complex shapes forming, conflicting design goals and so on). Therefore, proper design methodologies to reduce times and costs have to be developed mostly based on computer aided procedures. In this paper, a computer aided approach is proposed with the aim to offer a methodology able to solve very complex sheet metal stamping processes, in particular a progressive design approach based on the integration between numerical simulations and optimization methodologies is presented. In particular, Response Surface Method, Moving Least Squares approximation and Pareto optimal s…

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.
Identification of Defensive Performance Factors in the 2010 FIFA World Cup South Africa
2016
The aim of this study was to determine the efficacy of defensive play in elite football, to identify variables associated with the direct recovery of ball possession, and to propose a model for predicting the success of defensive transitions. We analyzed 804 transitions in the final stages of the Fedération Internationale Football Association (FIFA) World Cup 2010, and investigated the following variables using univariate, bivariate, and multivariate analyses: duration of defensive transition, possession loss zone, position of players at the start and end of the defensive transitions, defensive organization, general defensive approach, time of the match, position of defense, zone in which t…
