Magnetic Levitation is a process in which an object suspended with the support of magnetic field. Despite being unstable system, Systems (MAGLEV) have profound applications various fields engineering. MAGLEV systems are sensitive, unstable, and nonlinear uncertainties always pose challenge Controller Design. As solution, adaptive controllers came into existence adaptation mechanisms to cover sy...

Purpose Generally, humanoid robots usually suffer significant impact force when walking or running in a non-predefined environment that could easily damage the actuators due to high stiffness. In recent years, utilization of passive compliant series elastic (SEA) for driving humanoid's joints has proved capability many aspects so far. However, despite being widely applied biped robot research f...

In this article, an enhanced model reference adaptive control (EMRAC) algorithm is used to design a generic lateral-tracking controller for vehicle. This EMRAC different from the in literature as it adopts ?-modification approach bind gain of switching action. Moreover, extended Lyapunov theory discontinuous systems analytically prove ultimate boundedness closed-loop system when action bounded ...

In this paper, the competition between two supply chains and their elements is studied. Each chain consisted of a manufacturer and a distributor and the two chains compete in a market with single type of customer sensitive to price and delivery time. Therefore, this is a two-supply chain game and during the competition between two supply chains, elements of each supply chain (manufacturer and/o...

Abstract Late watergrass [ Echinochloa phyllopogon (Stapf) Koss.] has evolved multiple-resistance (MR) to herbicides in many areas worldwide and scientists wonder if this resistance imposed fitness cost or advantage on the resistant biotypes. As of weed also been recorded Greece, one susceptible (S), with ALS (penoxsulam, bispyribac, imazamox nicosulfuron + rimsulfuron) ACCase-cyhalofop (MRAC) ...

It has become a feasible green building development strategy to prepare recycled aggregate concrete (RAC) by processing construction and demolition (C&D) wastes into coarse (RCA). On the other hand, defects such as low strength easy cracking of RAC seriously limit its application in materials. In this paper, RCA was strengthened pre-coated nano-silica (NS) slurry improve performance. The ef...

The design of most adaptive control schemes is based on the certainty equivalence approach. According to this approach, a control law that can meet the control objective is first developed assuming the plant parameters are exactly known. Then, an adaptive law for estimating the unknown parameters of a certain plant parameterization in chosen to generate on-line estimates which are then u...
