Estimation of Nonstationary Process Variance in Multistage Manufacturing Processes Using a Model-Based Observer
(IEEE, 2018-08)
In this paper, we propose a recursive algorithm to estimate the process variance in multistage manufacturing or assembly processes. We use a replicated model that includes the process variance to be estimated as a time-varying ...
Aeronautical ground lighting system study: field measurements and simulations
(Institution of Engineering and Technology (IET), 2016)
Aeronautical ground lighting (AGL) systems are single-phase series circuits where constant current regulators supply transformers and luminaires. These systems provide visual reference to aircraft during airport operations. ...

A Markovian jump system approach for the estimation and adaptive diagnosis of decreased power generation in wind farms
(The Institution of Engineering and Technology (IET), 2019-08-30)
In this study, a Markovian jump model of the power generation system of a wind turbine is proposed and the authors present a closed-loop model-based observer to estimate the faults related to energy losses. The observer ...

The social changes that have taken place in recent decades have determined the evolution of the educational system. Society
nowadays demands new learning methods, focused on an appropriate selection and processing of ...
Stable receding-horizon scenario predictive control for Markov-jump linear systems
(Elsevier, 2017-12)
This paper discusses predictive control for constrained discrete-time Markov-jump linear systems (MJLS) which jump between a finite set of modes according to a Markov probabilistic transition/observation model, minimising ...
Post-processing optimization of electrospun submicron poly(3-hydroxybutyrate) fibers to obtain continuous films of interest in food packaging applications
(Taylor & Francis, 2017-08-08)
Polyhydroxyalkanoates (PHAs) are one of the most researched family of biodegradable polymers based on renewable materials due to their thermoplastic nature and moisture resistance. The present study was targeted to investigate ...
Complete Characterization of Thermoelectric Materials by Impedance Spectroscopy
(American Chemical Society, 2019-05-01)
Thermoelectric materials can directly convert waste heat into electricity. Because of the vast amount of energy available as waste heat in our society, these materials could contribute to reduce our dependence on fossil ...
Evaluation of the engineering performance of different bio-based aliphatic homopolyamide tubes prepared by profile extrusion
(Elsevier, 2017)
In the present study, three different commercial bio-based polyamides (bio-PAs), namely polyamide 610
(PA610), polyamide 1010 (PA1010), and polyamide 1012 (PA1012), were processed by profile extrusion
with an annular ...
