Fostering in-process inspection during process planning using tolerance charting
(Elsevier, 2013)
Integrated development of machining and inspection plans is essential in dynamic manufacturing environments, especially when right first time manufacturing is required. In this work, a methodology, based on a new and ...
A Triangulation Approach to Asymptotically Exact Conditions for Fuzzy Summations
(Institute of Electrical and Electronics Engineers (IEEE), 2009)
Many Takagi-Sugeno (T-S) fuzzy control-synthesis problems in the literature are expressed as the problem of finding decision variables in a double convex sum (fuzzy summation) of positive definite matrices. Matricespsila ...
Effect of the unidirectional drawing on the thermal and mechanical properties of PLA films with different L-isomer content
(Wiley Periodicals, Inc., 2013-02)
This work simulates the thermoforming process of two different L-isomer content PLA grades (95.6 and 98%), studying the influence on the induced morphology and the variation in the thermal and tensile properties. The ...
Optimal averaging time for improving observer accuracy of stochastic dynamical systems
(ElsevierISA, 2020-09-02)
In the problem of remote estimation by a centralized observer, improvements to the accuracy of observer estimates come at a cost of higher communication bandwidth and energy consumption. In this article we improve observer ...
Development and Characterization of Electrospun Biopapers of Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) Derived from Cheese Whey with Varying 3-Hydroxyvalerate Contents
(American Chemical Society, 2021-06-16)
In the present study, three different newly developed copolymers of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) with 20, 40, and 60 mol % contents in 3-hydroxyvalerate (3HV) were produced by the biotechnological ...
Multivariable phase-locked loop free strategy for power control of grid-connected voltage source converters
(Elsevier, 2022-05-17)
A multivariable control strategy in a reference frame for grid-connected voltage source converters (VSCs) without using a phase-locked loop (PLL) is presented in this paper. First, common VSC controls such as vector current ...
LK stability analysis of predictor-based controllers for discrete-time systems with time-varying actuator delay
(Elsevier, 2013-09)
This paper extends the scaled-small gain proposal in Li and Gao (2011) [14], modifying the Lyapunov–Krasovskii functional to analyze the robust stability of predictor-based state-feedback controllers for discrete-time ...
Protection Strategies for the Connection of Diode Rectifier-Based Wind Power Plants to HVdc Interconnectors
(Institute of Electrical and Electronics Engineers, 2020-10-05)
The connection of diode rectifier (DR)-based wind power plants (WPPs) to existing or planned high-voltage dc (HVdc) interconnectors can lead to important savings on cost and system robustness. Since the DR station usually ...
Techno-Economic Assessment of Energy Storage Technologies for Inertia Response and Frequency Support from Wind Farms
(MDPI, 2020-07-02)
This paper provides the result of a techno-economic study of potential energy storage technologies deployable at wind farms to provide short-term ancillary services such as inertia response and frequency support. Two ...
Influence of femtolaser notch sharpening technique in the determination of essential work of fracture (EWF) parameters
(Elsevier, 2009-06)
The fracture behaviour of a 0.5 mm thick ethylene-propylene block copolymer is analyzed using the essential work of fracture method, using DENT-type specimens. The influence of three experimental parameters in the technique ...
