This study presents a design method of power system stabilisers (PSSs) to damp system oscillations. The design is based on fuzzy logic and linear matrix inequality (LMI) techniques. The design guarantees a robust pole placement in a desired region in the complex plane for different loading conditions. Due to system non-linearity and load dependency, the whole wide range of operating condition is divided...
Nowadays, SoC uses Network on Chip (NoC) to connect its increasing number of building blocks. FPGAs, like SoCs, can use NoC to connect its increasing number of tiles, memories, DSP slices and embedded processors. But one drawback of using NoC is that increasing its router ports will affect the area, power and frequency of the system significantly. For FPGAs to benefit from the NoC approach we have...

Nowadays, impedance converter and inverter circuits are very vital for the fractional order circuit design. Mutators are one of the common circuits used for that purpose. So, two fractional order mutators are discussed in this work; the first one converts a resistance into a fractional order element. The second mutator family converts any fractional order element to a different fractional order element...
Genetic algorithm (GA) applications in analog design circuits play an important role with promising results.

This paper introduces a proposed methodology based on the genetic algorithm and the symbolic representation to generate equivalent op-amp configurations...
Wireless virtualization is a promising approach to foster innovation and prevent the ossification of wireless networks. Within a virtualized wireless network, multiple network slices, or virtual operators (VO), are co- hosted on the same physical infrastructure. A fundamental question in this environment is which multiplexing technique, TDMA, FDMA or SDMA, should be used to slice the network among...
The recent technology of intelligent systems is using multiple sensors to assess real-time information of the internal system states and the environmental operating conditions. In the case of sensor(s) transient faults, the dis-connection of the readings causes inappropriate actions. So the need for sensor fault detecting and estimating multiple sensor faults becomes an important issue to optimize...

The software-defined approach of cloud radio access networks (C-RANs) enables supporting multiple virtual operators (VOs) on the same physical infrastructure. In this shared environment, a coordinator is needed to manage the sharing of resources between the VOs. Designing a coordinator is about striking a good balance between the flexibility given to the VOs, and the efficiency of the resource utilization...
