... ⊆ ker(α) = 0, and so M is projective, as required. The proof of (5) ⇒ (1) is similar to that of (7) ⇒ (2) in Theorem 3.7. (7) ⇒ (1). By the proof of Proposition 2.3, every P -injective right R-module is ... semisimple Artinian. By a slight modification of the proof of [21, Theorem 2], we obtain the following Proposition 3.10. Let X b e a non-empty subset of a ring R. The following...

... unlike the delay, in the computation of the RE we are not conditioning on the fact of reaching the N-th node of the network, i.e., the last reachable node of the network. Therefore, also the packets ... conditions— this is the very idea of IF. The shape of p, as a function of d, is shown in Figure 5, for different values of c and ρ s . It can be observed that the PAF of SIF i...
