We investigate the effect of population III (Pop III) stars supernova explosion (SN) on high redshifts reionization history using latest Planck data. It is predicted that massive Pop $(130\text{ }\text{ }{M}_{\ensuremath{\bigodot}}\ensuremath{\le}M\ensuremath{\le}270\text{ }{M}_{\ensuremath{\bigodot}})$ explode energetically at end their stellar life as pair-instability supernovae (PISNe). In e...

Until now, road network generalization has mainly been applied to the task of generalizing from one fixed source scale to another fixed target scale. These actions result in large differences in content and representation, e.g., a sudden change of the representation of road segments from areas to lines, which may confuse users. Therefore, we aim at the continuous generalization of a road networ...

This work uses Linked Open Data for the generation of educational assessment items. We describe the streamline to create variables and populate simple choice item models using the IMS-QTI standard. The generated items were then imported in an assessment platform. Five item models were tested. They allowed identifying the main challenges to improve the usability of Linked Data sources to support...

ICT-enhanced research methods such as educational data mining (EDM) have allowed researchers to effectively model a broad range of constructs pertaining to the student, moving from traditional assessments of knowledge to assessment of engagement, meta-cognition, strategy, and affect. The automated detection of these constructs allows EDM researchers to develop intervention strategies that can b...
