A globally stable autopilot with wave filter using only yaw angle measurements [PDF]

open access: yesModeling, Identification and Control, 1996
A stable minimum phase transfer function from rudder angle to yaw angle is used to design a globally stable adaptive ship autopilot. First-order wave disturbances in yaw are filtered by applying a notch filter.

A Rapid Screening Program for Histoplasmosis, Tuberculosis, and Cryptococcosis Reduces Mortality in HIV Patients from Guatemala

open access: yesJournal of Fungi, 2021
Opportunistic infections (OIs) and advanced HIV disease (AHD) contribute to HIV-related mortality. Here, we analyzed the situation of AHD and OIs in a cohort of newly diagnosed HIV patients from Guatemala.

Effective Actions for Regge Piecewise Flat Quantum Gravity

open access: yesUniverse, 2022
We review the construction of the path integral and the corresponding effective action for the Regge formulation of General Relativity under the assumption that the short-distance structure of the spacetime is not a smooth 4-manifold, but a piecewise ...

SYNTHESIS OF FAULT ESTIMATION OBSERVER, BASED ON SPECTRAL MIMO H2 OPTIMIZATION

open access: yesСовременные информационные технологии и IT-образование, 2018
This paper is devoted to slowly varying additive fault detection with implementation of the observer-filter to be designed. Sensitivity of the observer to the external disturbance is to be minimized by the choice of its parameters.

Time-Slicing Path-integral in Curved Space [PDF]

open access: yesQuantum, 2022
Path integrals constitute powerful representations for both quantum and stochastic dynamics. Yet despite many decades of intensive studies, there is no consensus on how to formulate them for dynamics in curved space, or how to make them covariant with ...

Static group-bipartite consensus in networked robot systems with integral action

open access: yesInternational Journal of Advanced Robotic Systems, 2023
With the increasing complexity of modern industry, the traditional single-target control of swarm robots can no longer meet application requirements. Hence, this article addresses compound task control for swarm robot systems, where the control aim and ...
