Tribology behaviour of graphene-modified nanostructured Al2O3/3 % TiO2 coatings under boundary and mixed lubrication conditions
Elsevier Ltd (2024-06-15)This study is focused on the preparation of a self-lubricating coating via thermal spraying. This coating was designed to control friction and lubrication in both boundary lubrication (BL) and mixed lubrication (ML) regimes. ... -
Tuning and robustness analysis of event-based PID controllers under different event generation strategies
Taylor & Francis (2017-05)In this article, we propose practical rules for tuning event-based PID controllers with two sampling strategies: symmetric send-on-delta (SSOD) and regular quantification (RQ). We present a detailed analysis about the ... -
Tuning of PID Controllers based on simplified single parameter optimization
Taylor & Francis (2010)A simple method to design PID controllers in the frequency domain based on a simplified constrained optimiza- tion is proposed. The method is based on the use of a single tuning parameter, defined as the quotient between ... -
Tuning PID controllers with Symmetric Send-on-Delta sampling strategy
Elsevier (2019-10-23)A procedure for tuning PID controllers with SSOD sampling for FOPTD systems is proposed. It is based on the definition of a new robustness measure to avoid limit cycle oscillations, called the Tsypkin margin (MT). This ... -
Tuning procedure for event-based PI controllers under regular quantization with hysteresis
Elsevier (2021-04-20)In this paper a tuning procedure is proposed for event based PI controllers with Regular Quantization with Hysteresis (RQH) sampling law. The RQH is a generalization of Symmetric Send on Delta (SSOD) strategy which decreases ... -
Two-Scale Model Predictive Control for Resource Optimization Problems With Switched Decisions
IEEE (2022-05-30)Model predictive control (MPC) is widely used in resource optimization problems because it naturally deals with bounded controls and states and allows predictive information to be included. However, at each sampling ... -
University Social Responsibility towards Engineering Undergraduates: The Effect of Methodology on a Service-Learning Experience
MDPI (2018)Service-Learning (SL) experiences enable University Social Responsibility (USR) to be worked on in engineering studies as a core of education for Sustainability. The combined use of such experiences with active ... -
El urbanismo de la Valencia musulmana a través del Llibre del Repartiment
Universitat Politècnica de València (2023)De la urbe musulmana de Balansiya de mediados del siglo XIII se tienen pocos indicios. Sin embargo, el Llibre del Repartiment supone un valioso documento para establecer la topografía urbana de la Valencia árabe en el ... -
Using Generative Pre-Trained Transformers (GPT) for Electricity Price Trend Forecasting in the Spanish Market
MDPI (2024-05-13)The electricity market in Spain holds significant importance in the nation’s economy and sustainability efforts due to its diverse energy mix that encompasses renewables, fossil fuels, and nuclear power. Accurate energy ... -
Using osteogenic medium in the in vitro evaluation of bone biomaterials: Artefacts due to a synergistic effect
Elsevier (2023)In vitro tests using bone cells to evaluate the osteogenic potential of biomaterials usually employ the osteogenic medium (OM). The lack of correlation frequently reported between in vitro and in vivo studies in bone ... -
Using the instantaneous power of a free acceleration test for squirrel-cage motor parameters estimation
IEEE Power & Energy Society (2015-09)A new parameters determination method for squirrel-cage induction motors is presented. As a main contribution, the method uses the instantaneous electrical power and the mechanical speed measured in a free acceleration ... -
Uso del social media como estrategia de posicionamiento global para estudios de arquitectura
Asociación de profesores de expresión gráfica aplicada a la edificación (APEGA) (2015)The evolution of the internet has promoted the globalization of the current economic system. In this scenario, architecture studios may be forced to relocate its customer base, looking for new business opportunities outside ... -
Validez de la metáfora gráfica en el contexto actual de la comunicación
Sendemá (2012)La eficacia de los recursos metafóricos siguen siendo válidos en diversos campos de la comunicación. La operatividad de su uso exige que se tenga en cuenta el contexto del discurso, el entorno sociocultural y la experiencia ... -
