Variation of student engagement between different algebra tasks
2018
In this study, we analyse how 7th grade students’ engagement during small group work differed in two consecutive algebra lessons: in the first lesson students solved equa-tions and in the second lesson they created equations for other small groups to solve. Data was collected by videorecording the work of two groups in both lessons. Through directed content analysis, categories indicating student engagement were formed based on previous research and refined during analysis. The analysis revealed a change from individual engagement to collaborative engagement between lessons and an increase in many passive students’ engagement. Task characteristics which may affect the type and amount of eng…
A Telemetry, Tracking, and Command Antennas System for Small-Satellite Applications
2019
Circularly polarized (CP) antennas are used in space applications for telemetry tracking and command (TT&
Video Scene analysis for a configurable hardware accelerator dedicated to Smart Camera
2012
International audience; According to the Center for Research and Prevention of Injuries report, fall-caused injuries of elderly people in UE- 27 are five times as frequent as other injury causes which reduce considerably their mobility and independence. Among the diverse applications of computer vision systems, object detection and event recognition are of the most prominent related recognition and motion analysis, that is, researchers had the idea to spread it in fall detection. The fall event, extracted automatically from the video scene represents itself, crucial information that can be used to alert emergency. In this context, visual information on the corresponding scene is highly impo…
Smart Technology for the passive house
2013
Planning for sustainable policies aimed at identifying Smart urban spaces is determined by the parameters of Smart Cities model that encourage the production of intelligent building for construction energy efficient. The proposed article analyzes the effectiveness of the passive house in the Mediterranean area, offered by traditional building techniques, proposing a re-reading technology for the detection of a smart design methodology that can lead to the use of technologies with high energy efficiency.
Enhancing the Iterative Smoothed Particle Hydrodynamics Method
2021
Motivated by recent research on the iterative approach proposed for the smoothed particle hydrodynamics (ISPH) method, some ideas to improve the process are introduced. The standard procedure is enhanced iterating on the residuals preserving the matrix-free nature of the process. The method is appealing providing reasonable results with disordered data distribution too and no kernel variations are needed in the approximation. This work moves forward with a novel formulation requiring a lower number of iterations to reach a desired accuracy. The computational procedure is described and some results are introduced to appreciate the proposed formulation.
Splines in convex sets under constraints of two‐sided inequality type in a hyperplane
2008
The problem of minimization of a smoothing functional under inequality constraints is considered in a hyperplane. The conditions of the existence of a solution are obtained and some properties of this solution are investigated. It is proved that the solution is a spline. The method for its construction is suggested. First Published Online: 14 Oct 2010
Multispectral filter arrays: Recent advances and practical implementation
2014
Thanks to some technical progress in interferencefilter design based on different technologies, we can finally successfully implement the concept of multispectral filter array-based sensors. This article provides the relevant state-of-the-art for multispectral imaging systems and presents the characteristics of the elements of our multispectral sensor as a case study. The spectral characteristics are based on two different spatial arrangements that distribute eight different bandpass filters in the visible and near-infrared area of the spectrum. We demonstrate that the system is viable and evaluate its performance through sensor spectral simulation. Multispectral filter arrays: Recent advan…
Produire, diffuser et transmettre des savoirs portant sur la pauvreté et l’intervention sociale en milieu rural
2018
Tout en reprenant les enseignements de travaux de recherche conduits en France au sujet de la pauvreté et de l’intervention sociale en milieu agricole et rural, ce texte montre les conditions d’élaboration de savoirs s’appuyant sur des connaissances issues des sciences humaines et sociales et sur des observations conduites par et avec des professionnels de l’action sociale. Au-delà du repérage de situations qui caractérisent les espaces ruraux, il souligne l’apport de différentes méthodes d’investigation pour affiner le regard sur les conditions de vie des plus pauvres, les capacités d’adaptation dont ils disposent et les dispositifs qui leur sont destinés.
Participatory possibilities and multisensory teaching on YouTube
2014
Opettajien kognitiota ja ääntämisen opettamista koskeva tutkimus on ollut vähäistä. Myös uusien opettamiseen soveltuvien tekniikoiden ja verkko-opetusalustojen tutkimusta tarvitaan lisää, jotta voidaan todentaa niiden hyödyllisyys opetuksessa, minkä myötä käyttö voi lisääntyä. Edellä mainitut alat yhdistyivät tässä tutkimuksessa, jonka tarkoituksena oli selvittää huomioivatko englannin kielen opettajat YouTube-videopalveluun lataamissaan ääntämisvideoissa yksilölliset oppimistyylit, käyttävätkö he opetuksessaan moniaistillisia metodeja ja millaisia metodeja he hyödyntävät. Tutkimus tarkasteli onnistuivatko opettajat luomaan aktiivisen oppimisyhteisön YouTubeen ja toimimaan siinä itse aktiiv…
Choosing the Right Medium for Municipal eParticipation Based on Stakeholder Expectations
2012
Published version of a chapter in the book: Electronic Participation. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-33250-0_3 This paper examines the expectations and communication needs of relevant stakeholder groups for municipal eParticipation in a small Norwegian municipality. We identified relevant stakeholder groups with the municipality, and asked them about their communication preferences through a combined Delphi study and survey approach. The findings show that information about local issues, information about issues relevant for the individual stakeholder, and dialogue on business’ needs and employment are the three most important communication needs. …
