abstract. when a production facility is designed, there are various parameters affecting the number machines such as production capacity and reliability. it is often a tedious task to optimize different objectives simultaneously. the other issue is the uncertainty in many design parameters which makes it difficult to reach a desirable solution. in this paper, we present a new mathematical model...

In this work, two parametric L-Systems have been introduced to generate the figures of two series of nanostructures. These series consist of different spherical fullerenes with various number of carbon atoms. By specifying a parameter in each series a spherical fullerene can be determined. The members of the first series are C60 , C240 , C540 , C940 ,… which can be produced by applying paramete...

The present study aims to investigate the system of the visual transitivity by analyzing the images of American English file (2014) and Cutting edge (2005) series based on Halliday’s (1976) systemic functional linguistics and Kress and van leuween’s (1997-2006) social semiotics. The system of visual transitivity refers to a type of process which determines how represented participants are label...

in this paper, the development and optimization of power distribution control strategy (pdcs) have been performed for a hybrid energy storage systems (hess) of a series hybrid electric bus (sheb). a common pdcs is based on the use of ultra-capacitor (uc) pack. a new simple pdcs is developed as a battery based one. for the battery based pdcs, four parameters are introduced for tuning the pdcs pe...

in this paper, a consistent pattern with the optimal coordinated design of pss and sssc controller to improve the damping of low frequency oscillations is shown. in this design, sensing and signal transmission time delays are considered as effectiveness parameters. the design problem has been considered an optimization problem and biogeography-based optimization (bbo) algorithm is used for sear...
