The role of the lateral prefrontal cortex and anterior cingulate in stimulus–response association reversals [PDF]

open access: yes, 2007
Many complex tasks require us to flexibly switch between behavioral rules, associations, and strategies. The prefrontal cerebral cortex is thought to be critical to the performance of such behaviors, although the relative contribution of different ...

Optimal Control to Limit the Propagation Effect of a Virus Outbreak on a Network [PDF]

open access: yes, 2019
The aim of this paper is to propose an optimal control strategy to face the propagation effects of a virus outbreak on a network; a recently proposed model is integrated and analysed.

Real-time obstacle collision avoidance for fixed wing aircraft using B-splines [PDF]

open access: yes, 2014
A real-time collision avoidance algorithm is developed based on parameterizing an optimal control problem with B-spline curves. The optimal control problem is formulated in output space rather than control or input space, this is feasible because of ...

Controlled Cyclophotocoagulation [PDF]

open access: yesDer Ophthalmologe, 1998
In the past, the main problem of transscleral cyclophotocoagulation was related to the energy dosage of the individual effect. Since the target tissue is not directly observable, no information about the coagulation process was available to the surgeon.

Distributed Model Predictive Control Using a Chain of Tubes

open access: yes, 2017
A new distributed MPC algorithm for the regulation of dynamically coupled subsystems is presented in this paper. The current control action is computed via two robust controllers working in a nested fashion.

Air-fuel-ratio control of engine system with unknown input observer [PDF]

open access: yes, 2016
This paper presents an alternative control to maintain the air-fuel-ratio (AFR) of port-injected spark ignition (SI) engines at certain value, i.e. stoichiometric value, to improve the fuel economy.

Determination of dynamic flexure model parameters for ship angular deformation measurement [PDF]

open access: yes, 2012
In ship angular deformation measurement, Kalman filter used to estimate the deformation angle requires accurate dynamic flexure parameters. Traditionally, these dynamic flexure parameters are empirically set according to previous experience or determined

An adaptive observer-based parameter estimation algorithm with application to road gradient and vehicle's mass estimation [PDF]

open access: yes, 2012
A novel observer-based parameter estimation algorithm with sliding mode term has been developed to estimate the road gradient and vehicle weight using only the vehicle's velocity and the driving torque from the engine.
