This paper addresses the problem of characterizing analytically the autocorrelation structure of TCP traffic. We show that, under simple models, a single TCP connection generates traffic with an exponentially decreasing autocorrelation function. However, several TCP connections sharing a given link can generate traffic with long term dependencies, under the condition that the distribution of th...

This paper applies a Game-based Learning Evaluation Model (GEM) to assess whether the early warning – early action serious game “Ready!” is an effective component to add to existing Disaster Risk Reduction (DRR) training curricula, facilitated by NGO staff and applied at the community level. We developed a paper-based survey with 17 five-level Likert items and 15 open questions addressing the d...

1. (a) Let (X, ‖ · ‖) and (Y, ‖ · ‖) be normed spaces. Show that the following conditions on a family T ⊆ L(X, Y ) are logically equivalent: (1) {‖T ‖ : T ∈ T} is bounded in R; (2) {T : T ∈ T} is equicontinuous at some point of X ; (3) {T : T ∈ T} is equicontinuous at 0 ∈ X ; (4) {T : T ∈ T} is equicontinuous at every point of X . (This order may not be the most efficient one to prove round-rob...
