A flexible modular master programme in technology developped whithin a Tempus Project

In today’s competitive industry and in view of recent economic turbulences new frontiers of challenges emerge that require new educational paradigms accompanied by new tools and methodologies applicable to all aspects of engineering areas including the functional and organizational aspects. In accordance with the objectives stipulated by the Council of European Union work programme on the future of education and training, a Tempus project (2010-2013) has been mounted to develop a novel model for modular programmes to be used in education of technology specialities at master level. The model is implemented in manufacturing technology and management area and has general applicability for technology education in several fields. The main feature of this project consists in flexibility, adaptability, dynamic interactivity while consolidating theoretical and practical skills. MasTech is the name of a flexible modular master two-year programme in technology being developed according to the Bologna process that is to be adapted to the particular conditions of the universities in Algeria, Morocco and Tunisia. Three European Universities (Sweden, Germany, France) are involved in the project. This paper introduces MasTech and describes the different steps that have been followed to develop the master programme taking into account both academic and industrial needs and priorities. Results are expressed in terms of a professional master programme that has been submitted for accreditation.TEMPUS - MASTECH -2010 - 3369 / 001 - 00

Programme Flexible de Master en Technologies de Production

Un projet Tempus (2010-2013) entre 9 universités (trois Européennes et six Maghrébines) a conduit au montage d’un programme d’enseignement de Master en technologie de production mécanique (MASTECH), modulaire et enseigné en langue anglaise est présenté. Les objectifs de ce nouveau programme, le retour d’expérience ainsi que les contenus des matières sont présentés avec la spécificité de la mise au point d’un outil pédagogique d’enseignement (Package Education) qui facilitera le déroulement des enseignements, limitera les variances entre les partenaires maghrébins et devra permettre la mobilité des étudiants et des enseignants. Dans la même expérience, les points-clés de réussite de ce programme commun sont exposés. Il s’agit notamment de l’acquisition de matériels pédagogiques, de déroulement d’écoles d’été, de validations des contenus des modules pédagogiques, de transfert auprès des enseignants, des conventions avec des industriels locaux, de la convention entre partenaires maghrébins, du support pédagogique des universités européennes et des prévisions de mobilité. Les difficultés relatives à la coordination des différentes facettes du projet et à la langue d’enseignement sont aussi discutées. Le démarrage des enseignements élaborés par ce programme dans les cursus de formation est prévu pour septembre 2013 sous forme d’un master professionnalisant.programme européen TEMPUS 2010 - 3369 / 001 - 00

Pressure-induced transient structural change of liquid germanium induced by high-energy picosecond laser pulses

The temporal evolution of the reflectivity of germanium at 514 nm upon irradiation with single high-energy picosecond laser pulses has been measured using a streak camera. It is found that, for a well-defined high fluence range, the reflectivity of the laser-induced molten phase attains a value of 0.85, considerably above the value reported for liquid Ge in thermal equilibrium (0.75). This behavior is consistent with a strong densification of the liquid phase remaining after the explosive vaporization of a thin surface layer. Within the specified fluence interval, this anomalously high reflectivity state is independent of the fluence and lasts tens of nanoseconds. Both characteristics point to the presence of a pressure-induced transient structural change in liquid germanium. © 2005 American Institute of Physics.Peer Reviewe

A New Torque Control System of Permanent Magnet Synchronous Motor

The article describes a new approach to control of permanent magnet synchronous motor drive based on the analysis of the electromechanical transformation. The proposed control system provides quick response and low ripple of the motor torque and flux. To synthesis this control system, the authors put the electromagnetic torque and the modulus of stator flux vector as controlled values and use the Lyapunov's second method. In addition, the stator voltage constriction and ability of low-pass filtration are taken into account. The investigation of the proposed control system has carried out with the simulation and the experimental research which have confirmed that the proposed control system correspond to all above-mentioned control tasks and the permanent magnet synchronous motor controlled under this system may be recommended to use in robotics

Triggering white-light emission in a 2D imine covalent organic framework through lanthanide augmentation

Recently, covalent organic frameworks (COFs) have emerged as an interesting class of porous materials, featuring tunable porosity and fluorescence properties based on reticular construction principles. Some COFs display highly emissive monocolored luminescence, but attaining white-light emission from COFs is difficult as it must account for a wide wavelength range. White-light emission is highly desired for solid-state lighting applications, and obtaining it usually demands the combination of red-, green-, and blue-light components. Hence, to achieve the targeted white-light emission, we report for the first time grafting of lanthanides (Eu3+/Tb3+) on a two-dimensional imine COF (TTA-DFP-COF). We studied the luminescence properties of the hybrid materials prepared by anchoring Eu3+ (red light) and Tb3+ (green light) beta-diketonate complexes onto the TTA-DFP-COF. Reticular construction is exploited to design strong coordination of Eu3+ and Tb3+ ions into nitrogen-rich pockets of the imine COF. Mixed Eu3+/Tb3+ materials are then prepared to incorporate red and green components along with the inherent blue light from the organic moieties of the COF to produce white-light emission. We show that COFs have the potential for hosting Eu3+ and Tb3+ complexes, which can be tuned to obtain desired excitations for applications in the field of optoelectronics, microscopy, optical sensing, and bioassay
