During the last decades, educational contexts have transformed into complex technological and social ecologies, with mobile devices expanding the scope of education beyond the traditional classroom, creating so-called Ubiquitous Learning Environments (ULEs ...
This book deals with slums as a specific question and a central focus in urban planning. It radically reverses the official version of the history of world cities as narrated during decades: slums are not at the margin of the contemporary process of urbani ...
It is well known that an N-parameter d-dimensional Brownian sheet has no k-multiple points when (k - 1)d > 2kN, and does have such points when (k - 1)d < 2kN. We complete the study of the existence of k-multiple points by showing that in the critical cases ...
By modeling pedagogical scenarios as directed geometrical graphs and proposing an associated modeling language, this book describes how rich learning activities, often designed for small classes, can be scaled up for use with thousands of participants. Wit ...
In this Letter we investigate factors that influence the effective critical electric field for runaway-electron generation in plasmas. We present numerical solutions of the kinetic equation and discuss the implications for the threshold electric field. We ...
As the number of scientific papers getting published is likely to soar, most of modern paper management systems (e.g. ScienceWise, Mendeley, CiteULike) support tag-based retrieval. In that, each paper is associated with a set of \emph{tags}, allowing user ...
Teaching geomatics is a continuous challenge with the evolution of technologies which enables more and more accurate measurement and modelling of the environment. This paper will present an original pedagogical approach based on a teaching unit gathering s ...
Nanotechnology is a rapidly expanding and highly promising new technology with many different fields of application. Consequently, the investigation of engineered nanoparticles in biological systems is steadily increasing. Questions about the safety of suc ...
The physical face-to-face classroom still represents the core educational setting in which everyday CSCL practice takes place. However, current classrooms are not limited anymore to books, blackboards and other physical artifacts: laptops, tablets, digital ...

Displacement-based seismic design and assessment procedures require as key input parameter estimates of displacement capacities of the critical elements. The displacement capacities of unreinforced masonry (URM) walls are typically determined by means of q ...
