Modern control systems widely use network to decrease the implementation cost and also increase the performance. Although they have several advantages, they suffer from some limitations and deficiencies. Packet loss is one of the main limitations which affect the control system in different conditions and finally can lead to system instability. To prevent such problems it is important to model ...

The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...

Securing real-world operating systems is hard; dropping packets headed to those systems is easy. Thus, network-layer defenses have become indispensable to end-host security. Unfortunately, most defenses inflict collateral damage, require hardware modification, or necessitate coordination between organizations’ administrators. Yet, for all that, each defense addresses only a subset of attacks. T...

sulfur mustard (sm, bis- (2-chloroethyl) sulphide) is a chemical warfare agent that causes dna alkylation, protein modification and membrane damage. sm can trigger several molecular pathways involved in inflammation and oxidative stress, which cause cell necrosis and apoptosis, and loss of cells integrity and function. epigenetic regulation of gene expression is a growing research topic and is ...

Many studies have shown that the transmission control protocol (TCP) which is the major transport protocol in the Internet today is finding it increasingly difficult to cope with the growth of communication network capacities and applications. TCP’s inability to properly utilize network links is one of the problems. Besides, TCP takes a long time to achieve fairness between flows. Many of the n...
