This paper investigates the global fixed-time tracking control problem of nonlinear cascade systems with unknown high powers. In process design, a upper bound and lower powers are introduced to compensate system powers, state feedback controller is designed under any initial conditions. Based on Lyapunov stability analysis method theory, it verified that proposed can regulate output error disc ...

An adaptive version of growing and pruning RBF neural network has been used to predict the system output and implement Linear Model-Based Predictive Controller (LMPC) and Non-linear Model-based Predictive Controller (NMPC) strategies. A radial-basis neural network with growing and pruning capabilities is introduced to carry out on-line model identification.An Unscented Kal...

A class of explicit multistage time-stepping schemes with centered spatial di erencing and multigrid is considered for the compressible Euler and Navier-Stokes equations. These schemes are the basis for a family of computer programs ( ow codes with multigrid (FLOMG) series) currently used to solve a wide range of uid dynamics problems, including internal and external ows. In this paper, the com...

Independent censoring is a crucial assumption in survival analysis. However, this is impractical in many medical studies, where the presence of dependent censoring leads to difficulty in analyzing covariate effects on disease outcomes. The semicompeting risks framework offers one approach to handling dependent censoring. There are two representative estimators based on an artificial censoring t...

During quadrupedal trotting, diagonal pairs of limbs are set down in unison and exert forces on the ground simultaneously. Ground-reaction forces on individual limbs of trotting dogs were measured separately using a series of four force platforms. Vertical and fore-aft impulses were determined for each limb from the force/time recordings. When mean fore-aft acceleration of the body was zero in ...

Past studies in the IT outsourcing area have examined the management of IT outsourcing relationships from a variety of perspectives. The present paper extends this line of research. In this study, we take a multi-theoretic perspective to explore factors that determine the duration of continuing IT outsourcing relationships between vendor and client firms. Five ex-ante and two expost factors tha...

This paper presents two fault tolerant control (FTC) schemes for an octorotor UAV. The FTC schemes are based on an LPV system representation and utilizes a combination of sliding mode ideas and control allocation in order to take full advantage of the available redundant rotors in the octorotor configuration. A detailed synthesis procedure for the design of the two FTC schemes in the presence o...

abstract. in recent years several studies have shown that  control charts with adaptive schemes or double sampling plans detect both small and moderate shifts in the process mean more quickly than the traditional shewhart  chart. in the classical double sampling  chart, the difference between two points were placed in the central region of first stage was not considered. in this study, a new co...
