Control of underactuated systems with non-holonomic constraints has been an issue interest in recent years. These are hard to control because their linearization makes them uncontrollable and current approaches generally involve complex calculations. In this manuscript, a controller for trajectory tracking positioning second-order chained form system using simple approach based on linear algebr...

The cosmological relic density of the lightest supersymmetric particle (LSP) of type I string derived model is calculated. This model can accommodate large values of CP violating phases, and the electron and neutron electric dipole moments satisfy the experimental constraint. We show that the constraint from the electric dipole moment on the ratio between the gaugino masses implies that the mas...

calling tradition is among clearest areas which can be found in modern dramatic literary and artistic texts.  the ancient hero is quite well known  and since long has  found his place in literature and art of different nations especially in legends, epics, folk tales, oral literature and dramatic texts such that it was in a battle with other elements and defeated them. abou khalil alqabbani, th...

Multi-choice programming problems arise due to diverse needs of people. In this paper, multi-choice optimisation is applied bilevel transportation problem. This problem deals with at both the levels, upper as well lower. There are multiple choices for demand and supply parameters. The parameters respective levels converted into polynomials which transmute defined a mixed integer objective paper...

the doruneh fault is one of the longest and most prominent faults in iran. however, only two recorded historical earthquakes with magnitudes more than 7 might be related to this fault. for getting more information on this fault more investigation in different fields are required. fault displacement is one of the most important parameters needed to explore the fault activity. in this study, with...
