Dynamic positioning systems: An experimental analysis of sliding mode control
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
Vessel dynamic positioning (DP) systems are based on conventional PID-type controllers and an extended Kalman filter. However, they present a difficult tuning procedure, and the closed-loop performance varies with environmental ...
The cutting stock problem with multiple manufacturing modes applied to a construction industry
(2020-01-01)
This paper addresses the problem of multiple manufacturing modes integrated into the cutting stock problem, based on a real-life application of the concrete pole manufacturing. The main aim is to propose, formulate and ...
A data fusion approach with mobile phone data for updating travel survey-based mode split estimates
(2023)
Up-to-date information on different modes of travel to monitor transport traffic and evaluate rapid urban transport planning interventions is often lacking. Transport systems typically rely on traditional data sources ...

The synergy effect of carbon/glass/epoxy hybrid laminate in Mode I delamination: A physical microfracture analysis
(2020-11-01)
The adoption of carbon/glass fiber hybrid composites is an economical alternative to high-cost carbon/epoxy composites and helps to address environmental issues. However, the addition of another type of fiber modifies the ...
Scalar and Dirac quasinormal modes of scalar-tensor-Gauss-Bonnet black holes
(Iop Publishing Ltd, 2022-04-01)
This study explores the scalar and Dirac quasinormal modes pertaining to a class of black hole solutions in the scalar-tensor-Gauss-Bonnet theory. The black hole metrics in question are novel analytic solutions recently ...
Plasmon modes and screening in double metallic armchair graphene nanoribbons
(American Physical Society - APSCollege Park, 2013-10)
We theoretically study the plasmon modes in double parallelmetallic armchair graphene nanoribbons (AGNRs) separated by a distance Lb. Startingwith a single doped metallicAGNR at zero temperature,we showthe plasmon dispersion ...
Vector Mode Analysis of Ring-Core Fibers: Design Tools for Spatial Division Multiplexing
(2014)
Design tools have existed for decades for standard step-index fibers, with analytical expressions for cutoff conditions as a function of core size, refractive indexes, and wavelength. We present analytical expressions for ...
Tracking control of robot manipulators using second order neuro sliding mode
(2009)
Few works on neural networks-based robot controllers address the issue of how many units of neurons, hidden layers and inputs are necessary to approximate any functions up to a bounded approximation error. Thus, most ...
