We investigate the problem of simultaneously dominating all spanning trees of a given graph. We prove that on 2-connected graphs, a subset of the vertices dominates all spanning trees of the graph if and only if it is a vertex cover. Using this fact we pr... see more

The Computer Networking course commonly taught in mixed mode involving lecture and practical session whereas beside face-to-face theory session, students need to experience hands-on activities in order to appreciate the technology and contents. Neverthele... see more

This paper demonstrates how the mediation of situated simulations (sitsims) might disseminate an enhanced sense of reality for the user â?? regardless of the actual amount of authenticity in the reconstruction. Therefore, it will be argued, for sitsims to... see more
