Iterative Method for Tuning Multiloop PID Controllers Based on Single Loop Robustness Specifications in the Frequency Domain
(MDPI, 2021)
Multiloop proportional-integral-derivative (PID) controllers are widely used for controlling multivariable processes due to their understandability, simplicity and other practical advantages. The main difficulty of the ...
Stochastic Flow Analysis for Optimization of the Operationality in Run-of-River Hydroelectric Plants in Mountain Areas
(MDPI, 2024)
The highly temporal variability of the hydrological response in Mediterranean areas affects the operation of hydropower systems, especially in run-of-river (RoR) plants located in mountainous areas. Here, the water flow ...
Enhancing self-regulated learning in engineering education with lightboard videos as a support tool
(Wiley, 2024)
Background:
For engineering students, a lack of motivation and continuous study are common issues that lie in low academic performance. Active teaching with audio-visual systems, on the one hand, and self-regulated ...
Software Tool for Acausal Physical Modelling and Simulation
(MDPI, 2019)
Modelling and simulation are key tools for analysis and design of systems and processes from almost any scientific or engineering discipline. Models of complex systems are typically built on acausal Differential-Algebraic ...
Stiction compensation for low-cost electric valves
(Elsevier, 2023)
Nonlinear dynamics of control valves, such as stiction, can produce significant performance degradation in the control loops where they are involved. There are several works in the literature describing and modelling these ...
Manufacture of thermoplastic molds by fused filament fabrication 3D printing for rapid prototyping of polyurethane foam molded products
(Emerald, 2024)
Purpose:
Polyurethane (PUR) foam parts are traditionally manufactured using metallic molds, an unsuitable approach for prototyping purposes. Thus, rapid tooling of disposable molds using fused filament fabrication (FFF) ...
Low-Cost Prototype to Automate the 3D Digitization of Pieces: An Application Example and Comparison
(MDPI, 2021)
This work is aimed at describing the design of a mechanical and programmable 3D capturing system to be used by either 3D scanner or DSLR camera through photogrammetry. Both methods are widely used in diverse areas, from ...
Fluvial Dynamics and Hydrological Variability in the Chiriquí Viejo River Basin, Panama: An Assessment of Hydro-Social Sustainability through Advanced Hydrometric Indexes
(MDPI, 2024)
The objective of this study was to conduct a detailed analysis of the available flow series in the Chiriquí Viejo River basin in Panama. This paper examines the patterns of variation within these series and calculates ...
Modelado y análisis dinámico del olivo sometido a vibración mecánica
(Universidad de Córdoba, UCOPress, 2024)
En esta Tesis Doctoral se plantea la hipótesis de que es posible determinar el comportamiento dinámico del olivo cuando es sometido a vibración mecánica mediante la aplicación de modelos computacionales. Con base en esta ...
