in this paper, the unified power flow controller (upfc) is enhanced with a chaotic particle swarm optimization (cpso) damping controller in order to mitigate the low frequency oscillations (lfo) in a single machine infinite bus (smib) power system. the designed damping controller is an optimized lead-lag controller, which extracts the speed deviation of the generator rotor and generates the out...

This paper presents a distributed version of Mininet, an Openflow network emulator. Normally, Mininet emulates an entire network of hosts and switches, each running as a seperate process within a Linux container, all on the same machine. Unfortunately, emulating networks that require more resources than a single machine are currently impossible in Mininet. By extending Mininet with cross-machin...

We developed a system called Network Simulation Environment (NoSE) to simulate arbitrary network environments on a single Linux machine. NoSE provides a GUI and a management daemon that is capable of generating a complex network containing virtual hosts and switches with just a few clicks. Different virtual machines and network configurations can be archived in a library for later reuse. NoSE i...

This paper represents linkage network of queues consisting of biserial and parallel servers linked to a common server in series with a flowshop scheduling system consisting of two machines. The significant transportation time of the jobs from one machine to another is also considered. Further, the completion time of jobs/customers (waiting time + service time) in the queue network is the set...

Oscillations of power systems cause instability in power networks. Power system stabilizer (PSS) is used as a conventional method to damp these oscillations . Finding the optimized gain of PSS is one of the major problems in power system stability issue. In this paper, single machine connected to an infinite bus and 10-machines 39-bus network are considered for study. it's shown that finding th...

Nowadays, estimating the ampere consumption and achieve to the optimum condition from the perspective of energy consumption is one of the most important steps to reduce the production costs. In this research it is tried to develop an accurate model for estimating the ampere consumption by using the artificial neural networks (ANN).In the first step, experimental studies were carried out on 7 ca...

the problem of determining the sequence of a set of jobs with the objective function of minimizing the maximum earliness and tardiness in one machine is studied. production systems like jit are one of the many applications of the problem. this problem is studied in special cases and their optimal solutions are introduced with simple orders. in general, some effective conditions for neighboring ...

This proposal describes a model for the hourly number of peer-to-peer connection requests generated by a single machine in the Conficker-C botnet, as viewed by an observer who can monitor a fixed proportion of Internet address space. The goal of developing this peer-to-peer behavioral model is to estimate the number of infected machines in the botnet when machines cannot be directly observed. N...

objective: international diabetes organization estimates that there are 285 million people worldwide who suffer from diabetes, and this figure is expected to increase to 450 million in next 20 years. according to statistics issued by the world health organization, diabetes is considered among ten leading causes of death in world and its prevalence in the population is growing.this paper deals w...

Preventive maintenance is the essential part of many maintenance plans. From the production point of view, the flexibility of the maintenance intervals enhances the manufacturing efficiency. On the contrary, the maintenance departments tend to know the timing of the long term maintenance plans as certain as possible. In a single-machine production environment, this paper proposes a simulation–o...
