The aim of our research project called DidaTab – Didactics of Spreadsheets – is to get a more comprehensive picture of ICT uses in French schools and to obtain a better knowledge of students’ spreadsheet competencies. The exploratory study of curricula and practices shows very sparse use during secondary education. To achieve a more precise estimation of what students can do with spreadsheets, ...

contributes important knowledge in many procedures. Front the experience gained in tuning the Multiple Virtual Storage (MVS) operating system, a set of guidelines to help MVS installations avoid performance problems are suggested, along with an approach to tuning an MVS system. The guidelines can help a performance analyst isolate the cause of a performance problem. Not all possible problems...

PURPOSE To investigate the articulatory awareness of children with normal phonological development according to the variables gender, age and schooling, as well as to analyze their performances in speech perception and production tasks. METHODS Participants were 90 Preschool and Elementary School students, with ages between 5 and 7 years, who were evaluated using the Articulatory Awareness In...

Traditional parallel programming forces the programmer, apart from designing the application, to analyse the performance of this recently built application. This dljjjcult task of testing the behaviour of the program can be avoided with the use of an automatic performance analysis tool. Users are released from having to understand the enormous amount of performance information obtainedfrom the ...

BACKGROUND In some current healthcare settings, there is a noticeable absence of national institutions committed to the synthesis and use of evidence in healthcare decision- and policy-making. This absence creates a need to broaden the responsibilities of healthcare providers to include knowledge brokering and advocacy in order to optimize knowledge translation to other stakeholders, especially...

In this paper, we study the cooperative transport of a heavy object by a group of robots towards a goal. We investigate the case in which robots have partial and noisy knowledge of the goal direction and can not perceive the goal itself. The robots have to coordinate their motion to apply enough force on the object to move it. Furthermore, the robots should share knowledge in order to collectiv...

Introduction: Nowadays, X-ray radiographic imaging plays an essential role in disease diagnosis and treatment. In addition to benefits, X-rays have harmful effects for both patients and radiographers. Observing radiation protection principles reduces radiation exposure and the probability of radiation risk. Therefore, we sought to assess the knowledge, attitude, and performance of radiographers...
