In this paper we demonstrate the application of time-varying graphs (TVGs) for modeling and analyzing multi-robot foremost coverage in dynamic environments. In particular, we consider the multi-robot, multi-depot Dynamic Map Visitation Problem (DMVP), in which a team of robots must visit a collection of critical locations as quickly as possible, in an environment that may change rapidly and unp...

There is an ever-increasing interest in investigating dynamics in timevarying graphs (TVGs). Nevertheless, so far, the notion of centrality in TVG scenarios usually refers to metrics that assess the relative importance of nodes along the temporal evolution of the dynamic complex network. For some TVG scenarios, however, more important than identifying the central nodes under a given node centra...

Background: Game-based education is fast becoming a key instrument in medical education. Method: In this study, papers related to games were filtered and limited to full-text peer-reviewed published in English. Results: To the best of researchers’ knowledge, the concepts used in the literature are varied and distinct, and the literature is not conclusive on the definition of educational...

Recent issues of ARE Update featured articles evaluating the failures of two California marketing cooperatives, Tri Valley Growers (TVG) and Rice Growers Association (RGA). Along with Blue Anchor’s dissolution and Calavo’s conversion, these combined events have created doubts about the future of cooperatives in California agriculture. Restructured forms of cooperatives are emerging. For example...

bourdieu had the help of two concepts of “habitus” and “field” to explain his theory and to show social distinctions, he argues that the social world is made up of different fields. each field has its own certain habitus and they can change depending on the field`s change. he believes that modern world is based on distinction. this distinction is clear in structural concepts such as space, clas...
