Ideal observer models have proven useful in investigating assumptions about human information processing in a variety of perceptual tasks. However, these models have not been applied in the area of higher-order category learning. We describe a simple Bayesian ideal observer and apply it to empirical data on category learning. We describe an experiment in which we found that acquisition of famil...

this paper addresses adaptive observer design problem for joint estimation of the states and unknown parameters for a class of nonlinear systems which satisfying one-sided lipschitz and quadratic inner bounded conditions. it’s shown that the stability of the proposed observer is related to finding solutions to a quadratic inequality consists of state and parameter errors. a coordinate transform...

An interpretation of special relativity is presented with alternative principles that treat an appearance of simultaneity as physically real. This implies instantaneous propagation of incoming light, but maintains light’s invariable propagation rate of c by using an alternative measure of speed. The relativistic Doppler effect is derived from physical principles based on the direct appearance o...

This paper presents a new observer design methodology for a time varying actuator fault estimation. A new linear matrix inequality (LMI) design algorithm is developed to tackle the limitations (e.g. equality constraint and robustness problems) of the well known so called fast adaptive fault estimation observer (FAFE). The FAFE is capable of estimating a wide range of time-varying actuator fault...

Steering assist system controls the force transfer behavior of the steering system and improves the steering probability of the vehicle. Moreover, it is an interface between the diver and vehicle. Fault detection in electrical assisted steering systems is a challenging problem due to frequently use of these systems. This paper addresses the fault detection and reconstruction in automotive elect...

this paper employs nonlinear disturbance observer (ndo) for robust trajectory-free nonlinear model predictive control (nmpc) of biped robots. the ndo is used to reject the additive disturbances caused by parameter uncertainties, unmodeled dynamics, joints friction, and external slow-varying forces acting on the biped robots. in contrary to the slow-varying disturbances, handling sudden pushing ...

in this paper, a reaction system consisting of two parallel, non-isothermal autocatalytic reactions in a continuous stirred tank reactor (cstr) has been considered. reactor chaotic behavior is possible for certain values of system parameters. two types of controllers are designed and compared in order to control both the reactor temperature and the product concentration. the first controller is...

this study was aimed at determining intra and inter-observer concordance rates in the gleason scoring of prostatic adenocarcinoma, before and after a web-based educational course. in this self-controlled study, 150 tissue samples of prostatic adenocarcinoma are re-examined to be scored according to the gleason scoring system. then all pathologists attend a free web-based course. afterwards, the...
