Implications for (d,p) reaction theory from nonlocal dispersive optical model analysis of $^{40}$Ca(d,p)$^{41}$Ca [PDF]
, 2016 The nonlocal dispersive optical model (NLDOM) nucleon potentials are used for the first time in the adiabatic analysis of a (d,p) reaction to generate distorted waves both in the entrance and exit channels.

A New Approach to Nonlinear State Observation for Affine Control Dynamical Systems
Applied Sciences, 2023 In this work, a Nonlinear Higher Order Extended State Observer (NHOESO) is presented to replace the Linear Extended State Observer (LESO) used in Conventional Active Disturbance Rejection Control (C-ADRC) solutions.

Representation theory for the Kriz model
, 2012 The natural action of the symmetric group on the configuration spaces F(X; n) induces an action on the Kriz model E(X; n). The represen- tation theory of this DGA is studied and a big acyclic subcomplex which is Sn-invariant is described.Comment: 25 ...

Experimental assessment of bi-directional transmission distribution functions using digital imaging techniques [PDF]
, 2005 Many daylighting applications require a precise knowledge of the directional transmission features of advanced fenestration materials. These photometric properties are described by a bi-directional transmission distribution function (BTDF), whose ...

LESO-Based Nonlinear Continuous Robust Stabilization Control of Underactuated TORA Systems
Actuators, 2022 In this paper, we consider the robust stabilization control problem of underactuated translational oscillator with a rotating actuator (TORA) system in the presence of unknown matched disturbances by employing continuous control inputs. A nonlinear continuous robust control approach is proposed by integrating the techniques of backstepping and linear ...

Extended State Observer-Based Sliding Mode Control Design of Two-DOF Lower Limb Exoskeleton
Actuators, 2023 Due to some model uncertainties and unknown friction disturbances that exist in the 2-DOF lower limb exoskeleton, a linear extended state observer (LESO) is proposed to estimate the unmeasurable angular velocity of two joints and the lumped uncertainties
