In this paper we study the problem of applicationbased Human-Robot Interaction (HRI). We introduce a problem called The Human State Problem (HSP) and we propose a robotic architecture that partially solves this problem. In the HSP the goal is to keep a user that interacts with a robotic application in a desired state; in most cases this state is happy or satisfied. The robotic application uses ...

 The purpose of this study is to investigate the effects of asynchronous computer-mediated versus conventional corrective feedback on learners' writing accuracy. Three groups of learners took part in the study: asynchronous feedback group, conventional feedback group, and a control group. Asynchronous feedback group students received explicit feedback on the targeted structure via e-mail, while...

This paper, deals with an indirect adaptive fuzzy control of discrete-time MIMO nonlinear systems with parametric variations. The synthesis of the state feedback control law is based on the T-S fuzzy models developed by a local description of the considered system. In the first step, gradient method is used to adjust model parameters locally estimated by the fuzzy model. The state feedback cont...

Hand hygiene (HH) is the single most important factor in the prevention of health care-acquired infections. The 3 most frequently reported methods of measuring HH compliance are: (1) direct observation, (2) self-reporting by health care workers (HCWs), and (3) indirect calculation based on HH product usage. This article presents the results of a 12-month multicenter collaboration assessing HH c...

Facilitative effects of some species on others are a major driver of biodiversity. These positive effects of a benefactor on its beneficiary can result in negative feedback effects of the beneficiary on the benefactor and reduced fitness of the benefactor. However, in contrast to the wealth of studies on facilitative effects in different environments, we know little about whether the feedback e...

this study aims to better understand the effect of practice schedule and feedback providing types. in two separate experiments the contextual interference effect in bandwidth and self-control feedback conditions on relative and absolute timing learning was examined. in experiment i, the effect of contextual interference using bandwidth and self-control feedback on absolute timing learning (para...

26 Somatostatin (SST) is a peptide synthesized and released by a class of neostriatal 27 local GABAergic interneurons which, to some extent, are in charge of the 28 feedforward inhibitory circuit. Spiny projection neurons (SPNs) make synapses 29 with each other via their local axon collaterals shaping the feedback inhibitory 30 circuit. Both inhibitory circuits, feedforward and feedback, are re...

System identi cation deals with the construction of mathematical models of dynamical systems using measured data. Closed-loop identi cation is what results when performing the identi cation experiment under output feedback, that is, in closed loop. In this thesis we study a number of closed-loop identi cation methods, both classical and more recently suggested ones. A common feature of the meth...

We study in this paper the problem of adaptive trajectory tracking for nonlinear systems affine in the control with bounded state-dependent and time-dependent uncertainties. We propose to use a modular approach, in the sense that we first design a robust nonlinear state feedback which renders the closed loop input to state stable(ISS) between an estimation error of the uncertain parameters and ...
