Consider that $u_0$ nodes are aware of some piece of data $d_0$. This note derives the expected time required for the data $d_0$ to be disseminated through-out a network of $n$ nodes, when communication between nodes evolves according to a graphical Markov model $overline{ mathcal{G}}_{n,hat{p}}$ with probability parameter $hat{p}$. In this model, an edge between two nodes exists at discrete time $k in mathbb{N}^+$ with probability $hat{p}$ if this edge existed at $k-1$, and with probability $(1-hat{p})$ if this edge did not exist at $k-1$. Each edge is interpreted as a bidirectional communication link over which data between neighbors is shared. The initial communication graph is assumed to be an Erdos-Renyi random graph with parameters $(n,hat{p})$, hence we consider a emph{stationary} Markov model $overline{mathcal{G}}_{n,hat{p}}$. The asymptotic "$u_0$-expected flooding time" of $overline{mathcal{G}}_{n,hat{p}}$ is defined as the expected number of iterations required to transmit the data $d_0$ from $u_0$ nodes to $n$ nodes, in the limit as $n$ approaches infinity. Although most previous results on the asymptotic flooding time in graphical Markov models are either emph{almost sure} or emph{with high probability}, the bounds obtained here are emph{in expectation}. However, our bounds are tighter and can be more complete than previous results.

A system and method can support a flooding mechanism using a multicast group in a middleware machine environment. The middleware machine environment can comprise a gateway instance that includes an external port for receiving one or more data packets from an external network. The middleware machine environment also comprises one or more host servers, each of which is associated with one or more virtual machines that can process the data packets. Furthermore, said host servers can provide virtual interfaces that belong to a virtual hub associated with the gateway instance. At least one said packet is a flooded packet that is specified with an unknown destination address when it is received at the external port. The gateway instance operates to send the flooded packet to the multicast group that operates to forward the flooded packet to one or more said host servers in the multicast group.

An apparatus comprises a plasma flood gun for neutralizing a positive charge buildup on a semiconductor wafer during a process of ion implantation using an ion beam. The plasma flood gun comprises more than two arc chambers, wherein each arc chamber is configured to generate and release electrons into the ion beam in a respective zone adjacent to the semiconductor wafer.
