As stated by the United Nations (2013), children have the right to play, defined as playing without adult or external rules, or predefined aims. Its mere purpose is to enjoy oneself, alone or with others. Yet the benefits of play on children’s physical and mental health development are significant. Playing in outdoor areas, like at schoolyards, has an added value, as outdoor play gives children the opportunity ...

No. of bitstreams: 0 Previous issue date: 2007-11-01; This report presents the capabilities of the CMS experiment to explore the rich heavy-ion physics programme offered by the CERN Large Hadron Collider (LHC). The collisions of lead nuclei at energies , will probe quark and gluon matter at unprecedented values of energy density. The prime goal of this res...
The conflicting issues of growing demand for electrical energy versus the environmental concerns have left the energy industries practically with one choice: to turn into renewable energies. This duality has also highlighted the role of power transmission systems as energy delivery links in two ways, considering the increased demand of load centers, and the integration of large-scale renewable generation units ...
Photovoltaic (PV) as one of the most promising energy alternatives brings a set of serious challenges in the operation of the power systems including PV system protection. Accordingly, it has become even more vital to provide reliable protection for the PV generations. To this end, this paper proposes two-stage data-driven methods. In the first stage, a feature selection method, namely t-distributed stochastic ...
