Trajectory Control for Car-like Mobile Robots via Frugal Predictive Control with Integrated Disturbance Rejection

Actuators
This paper presents a hierarchical control architecture for high-precision trajectory tracking of a car-like mobile robot (CLMB) operating under external disturbances arising from normal and tangential wheel forces.

Theoretical study of lithium clusters by electronic stress tensor

AIP Advances, 2012
We study the electronic structure of small lithium clusters Lin (n = 2 ∼ 8) using the electronic stress tensor. We find that the three eigenvalues of the electronic stress tensor of the Li clusters are negative and degenerate, just like the stress tensor

Representation Theorem for Stochastic Differential Equations in Hilbert Spaces and its Applications [PDF]

Surveys in Mathematics and its Applications, 2006
In this survey we recall the results obtained in [Ungureanu,Electronic Journal of Qualitative Theory of Differential Equations, 2004] where we gave a representation theorem for the solutions of stochastic differential equations in Hilbert spaces.

On positive-realness and stability of switched linear differential systems

, 2013
We present some results regarding the stability of switched linear differential systems (SLDS) in the behavioral framework. Positive-realness is studied as a sufficient condition for stability and some implications derived from the use of positive-real ...

IEC 61850-Based Centralized Busbar Differential Protection with Data Desynchronization Compensation

Energies, 2020
This paper proposes an IEC 61850-based centralized busbar differential protection scheme, in which data desynchronization between intelligent electronic devices (IEDs) leads to differential current errors.

Serological Benefit of SARS‐CoV‐2 Vaccination Relative to Infection in Children With Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with acute lymphoblastic leukemia (ALL) are at risk of severe outcomes from SARS‐CoV‐2 (SCV2). In the post‐pandemic context, where most children have been infected with SCV2, there are limited data on whether vaccination remains beneficial in children with ALL.
