We analyze the asymptotic variance of distributed consensus algorithms over large-scale switching random networks. Our analysis is focused on consensus algorithms over large, i.i.d., and directed Erdo??s-Re??nyi random graphs. We assume that every agent can communicate with any other agent with some fixed probability c/n, where c is the expected number of neighbors of each agent and n is the size...
Due to the rapid increase of population and the necessity of providing adequate drinkable water supplies, which meet hygiene conditions, modern techniques are applied for water treatment. In particular, this study introduces a flexible model for describing, calculating and estimating the volume of water in distribution tanks through all phases of treatment processes. The model considers a typical...
In distributed file systems, a need may arise for relocation of the file system to a different server. This is one of the fundamental mechanisms for ensuring file service availability for the geographically distributed clients. However, migration or replication in many such systems requires that the client or client side daemons take active measures for accessing the alternate servers, thus compromising...
B-ISDN is expected to support diverse applications ranging from lowest to highest bit rate communications. In this mode, information is transferred in a connection oriented fashion among communicating entities using fixed size packets know as ATM cell. The Batcher-Banyan combinational switches are one of high speed space division switches. But it finds difficulties in routing two cells with same destination...
A new model of network security assessment is proposed in this paper. A single IT entity is evaluated through EAL; The composite IT entities are evaluated by CAP. The model analyzes the security value of network elements, and adopts the Geometric mean method to determine the security value of the entire network. The effectiveness of this method is validated through the evaluation of a practical system.
This letter concerns with robust exponential stability of stochastic neural networks with Markovian switching. By applying Lyapunov functional method, a sufficient stabilization condition is developed in terms of matrix inequalities. The result is also compared with the previously reported results in the literature. Finally, one simulation example is provided to illustrate the effectiveness of the...
It has been reported that Internet Protocol (IP) packet traffic exhibits self-similarity or long range dependence (LRD) and causes the degradation of switch performance. Therefore, it is crucial for an appropriate buffer design of switch. In this paper, we investigate the packet loss behavior of the switch under self-similar variable packet length traffic by modeling it MMPP/M/1/K as queueing system...
Unreasonable torque ripple in the permanent magnet synchronous motor (PMSM) direct torque control (DTC) drives is caused by the inconsistency between the actual effect on torque of the voltage vector and the exception of the switching table. In order to solve this problem, the number of available non-zero voltage vectors is up to 12 in a sector by dividing stator flux circle into 12 sectors and the...
