Main contribution of this work is improving transient stability by installing Flexible AC Transmission System (FACTS) in power systems. For do this, Unified Power Flow Controller (UPFC) has been selected. Also a novel structure has been suggested to improve classic Harmony Search algorithm and suggested improved Harmony Search (iHS) algorithm. This algorithm has been used to obtain UPFC paramet...

this paper presents a clear monograph on the optimization of thermal instability resistance of the fg (functionally graded) flat structures. for this aim, two fg flat structures, namely an fg beam and an fg circular plate, are considered. these structures are assumed to obey the first-order shear deformation theory, three-parameters power-law distribution of the constituents, and clamped bounda...

We obtain spacetimes generated by static and spinning magnetic string sources in Einstein Relativity with negative cosmological constant (Λ < 0). Since the spacetime is asymptotically a cylindrical anti-de Sitter spacetime, we will be able to calculate the mass, momentum, and electric charge of the solutions. We find two families of solutions, one with longitudinal magnetic field and the other ...

Abstract We studied the magnetic effects on chiral transition and melting properties of vector axial-vector mesons in improved soft-wall AdS/QCD model under a charged background, which is solved perturbatively from an Einstein–Maxwell system with negative cosmological constant. The phase diagrams for both meson have been obtained. show that inverse catalysis emerged naturally model. also find f...

Data clustering is a key technique in the field of data mining, pattern recognition, bioinformatics and machine learning which concerns the organization and unexplored relationship between the huge amounts of data. It can analyse the data without knowing the size and distribution. Thus, this paper presents a new approach based on the charged system search (CSS) with chaotic map for partition cl...

Best Management Practices (BMPs) are implemented in a watershed to reduce the amount of non-point source pollutants transported to water bodies. However, an optimization algorithm is required to choose the efficient type, size, and location of BMPs for application in a watershed for improving the water quality. In this study, the Charged System Search, a well-known and powerful meta-heuristic o...

We investigate thermodynamic properties of noninteracting charged bosons in the presence of externally applied electric and magnetic "elds. Using the semiclassical density of states, we obtain the condensate fraction, chemical potential, total energy, and speci"c heat of a system of "nite number of charged Bose particles. We conclude that Bose}Einstein condensation of the charged Bose gas occur...

the operation of a distribution system in the presence of distributed generation systems has someadvantages and challenges. optimal sizing and siting of dg systems has economic, technical, andenvironmental benefits in distribution systems. improper selection of dg systems can reduce theseadvantages or even result in deterioration in the normal operation of the distribution system. dgallocation ...

The search for Noether point symmetries for non-relativistic charged particle motion is reduced to the solution for a set of two coupled, linear partial differential equations for the electromagnetic field. These equations are completely solved when the magnetic field is produced by a fixed magnetic monopole. The result is applied to central electric field cases, in particular to the time-depen...
