In this paper is presented the study of fuzzy logic power stabilizer for stability of a single machine infinite bus (SMIB). The performance of the system with fuzzy logic based power system stabilizer is compared with the system having conventional power system stabilizer and system without power system stabilizer. The results show that the system with fuzzy logic controller is capable of stabi...

A learning machine, like all machines, is an open system driven far from thermal equilibrium by access to a low entropy source of free energy. We discuss the connection between machines that learn, with probability error, and optimal use thermodynamic resources for both classical quantum machines. Both fixed point spiking perceptrons are discussed in context possible physical implementations. A...

Cloud computing is a result of the continuing progress made in the areas of hardware, technologies related to the Internet, distributed computing and automated management. The Increasing demand has led to an increase in services resulting in the establishment of large-scale computing and data centers, in addition to high operating costs and huge amounts of electrical power consumption. Insuffic...

System level virtualization provides several advantages: (i) customization is eased since virtual machines may be based on different systems; (ii) virtual machines are isolated from hardware, subsequently applications are isolated via the virtual machines; (iii) basic fault tolerance mechanisms – pro-active fault tolerance through virtual machine migration and virtual machine snapshot/restore; ...

In the special machines and custom made machine industry, machine manufacturers have to deal with maintenance services in spread market, while individualization of customer demands increases complexity to maintenance services. That is the case in stone cutting machines manufacturing business, where maintenance is a critical factor because of the high customization of each machine and because of...

A wide range of software units can be classified as state machines. We extend conventional state machine notations by adding regular expressions of events and unions of source states to state machine transitions. Reusable software components are generated from these extended state machine specifications. Component specification and generation are illustrated in Java.

Klinkenberg permeability is an important parameter in tight gas reservoirs. There are conventional methods for determining it, but these methods depend on core permeability. Cores are few in number, but well logs are usually accessible for all wells and provide continuous information. In this regard, regression methods have been used to achieve reliable relations between log readings and Klinke...

Optimal preventive maintenance and repairmen policies for a system of machines subject to degradation with age and intermittent breakdowns and repairs are derived using optimal control theory. When this system of machines forms part of a dynamic process control system, a method of obtaining optimal closed-loop control law is indicated. I . INTRODUC~ON Many large industrial systems have two dist...

Tendency to optimization in last decades has resulted in creating multi-product manufacturing systems. Production planning in such systems is difficult, because optimal production volume that is calculated must be consistent with limitation of production system. Hence, integration has been proposed to decide about these problems concurrently. Main problem in integration is how we can relate pro...

Conventional utilization-based power model is effective for measuring the power consumption of physical machines. However, in virtualized environments its accuracy cannot be guaranteed because of the recursive resource accessing among multiple virtual machines. In this paper, we present a novel virtual machine scheduling algorithm, which uses Performance-Monitor-Counter as heuristic information...
