Nowadays, economic load dispatch between generation units with least cost involved is one of the most important issues in utilizing power systems. In this paper, a new method i.e. Water Cycle Algorithm (WCA) which is similar to other intelligent algorithm and is based on swarm, is employed in order to solve the economic load dispatch problem between power plants. In order to investigate the eff...

In this paper, using parabolic mirrors, a solar field was designed, which was related to a storage tank for a residential complex in the city of Tafresh located in the center of Iran. The design was performed for the existing oils: VP1, THERMINOL 66, THERMINOL 59. Finally, considering an organic cycle with R123 as working fluid and assuming a minimum length required for oil flow rate to reach a...

Thermal stress, wear and material damage produce effects of high-cycle fatigue failures in aircraft engines. The loading configuration on turbine blades of aircraft engines consists of an axial load. The axial load is the centrifugal force combined with the tensile and compressive loads, caused by the natural vibrations of the blades themselves. Low-cycle fatigue and high-cycle fatigue loading ...

The e ect of adding a superimposed high-frequent strain load, denoted as a high-cycle fatigue strain component, upon a strain-controlled thermomechanical fatigue test has been studied on a compacted graphite iron ENGJV-400 for di erent thermo-mechanical fatigue cycles and high-cycle fatigue strain ranges. It is demonstrated that the successive application of an high-cycle fatigue load has a con...

Combined high and low cycle fatigue (CCF) generally induces the failure of aircraft gas turbine attachments. Based on the aero-engine load spectrum, accurate assessment of fatigue damage due to the interaction of high cycle fatigue (HCF) resulting from high frequency vibrations and low cycle fatigue (LCF) from ground-air-ground engine cycles is of critical importance for ensuring structural int...

wireless sensor networks(wsn) have unique properties that distinguished them from other wireless networks and have special challenges. not-chargeable, not-changeable and limited power supplies of sensor nodes is the most important challenge of this networks, and if the power supply of node expired, a part of data maybe lost. because of the importance of covers in wireless sensors, in this work ...

based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. however, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. to resolve this problem, hybridization of the fuel cell and energy storage device...
