Etapas en el desarrollo de la metrología sanitaria en España
Uno de los objetivos clave en el campo de la metrología a nivel internacional es que las medidas realizadas en el campo de la salud sean trazables, que dichas medidas sean fiables e intercomparables entre distintos hospitales ... -
Metodologías innovadoras para la difusión en metrología. Escape room virtuales sobre metrología legal y sistema internacional de unidades. Indicadores para el seguimiento de los proyectos
Las nuevas tecnologías han irrumpido en la vida del ciudadano de una manera drástica como consecuencia del COVID. La realización de reuniones virtuales, la digitalización acelerada de actividades que se consideraban casi ... -
Diseño óptico de un patrón cuántico de presión basado en la medida del índice de refracción de un gas
El proyecto EMPIR 18SIB04 Quantum Pascal trabaja en el desarrollo de un patrón de presión con soporte cuántico para mejorar la incertidumbre y la trazabilidad que ofrecen los métodos actuales. Este proyecto utiliza un ... -
Development and commissioning of a hydrogen ion source for the CERN ALPHA experiment
The CERN ALPHA experiment makes precision measurements of antihydrogen atoms held in a superconducting magnetic minimum trap. Recent studies of the antihydrogen spectrum have provided unique tests of fundamental physics, ... -
Detection and properties of voltage impasse regions in the presence of nonlinear static loads
This paper introduces a generic method for detection of Voltage Impasse Region(s) (V IR) that may appear when power system dynamics are represented by a set of differential algebraic equations. The recently introduced V ... -
Small-signal analysis of a microgrid with secondary control including the dynamics of primary control and communication delays
Microgrids (MGs) facilitate the integration of distributed energy resources (DERs) in electrical grids. To coordinate the operation of these DERs, a three-level hierarchical control is commonly used. In general, different ... -
Addressing unfeasibilities of energy storage systems participating in energy and reserve markets
Optimization algorithms formulated to define the joint participation of Energy Storage Systems (ESSs) in energy and reserve markets often lead to unfeasibilities related to the available energy stored in the ESS, particularly ... -
Guaranteeing the provision of Primary Frequency Control services by distributed generation
In this work, a tool for the evacuation of Primary Frequency Control (PFC) service by generators connected to the distribution network is proposed. To achieve this goal, a linear AC Optimal Power Flow (OPF) model with a ... -
Scalability evaluation of a Modbus TCP control and monitoring system for Distributed Energy Resources
Modbus TCP is a communication protocol widely used in industrial applications and to communicate with energy assets such as inverters or data loggers. The communications technologies involved in the management of distributed ... -
A parametric methodology for the assigment of pressure values versus refractive measurement
The 18SIB04 QuantumPascal EMPIR project aims to achieve quantum-based pressure standards. One of the most promising ways of achieving this goal is the use of a Fabry-Perot interferometer for measuring the refractivity of ... -
Uncertainty in mechanical deformation of a Fabry-Perot cavity due to pressure: towards best mechanical configuration
In this paper, a study of the deformation of a refractometer use to achieve a quantum realization of the Pascal is made. First, the propagation of the uncertainty in the measure of pressure due to mechanical deformation ... -
Remote open phase faults in the start-up transformers of a nuclear power generating station
United States Nuclear Regulatory Commission (US NRC) has requested to the US nuclear power generating industry that Open Phase Conditions (OPCs) should be automatically detected. This requirement has been extended by other ... -
The impact of industrial policymaking on the economics of low-emission technologies: the TRANSid model
Basic materials like steel, cement, aluminium and (petro)chemicals are the building blocks of our industrialised societies, but today their production is highly energy and emission-intensive. Hence, these industries need ... -
Eliminación de ruido en señales acústicas para detección de fallas en materiales compuestos
Las mediciones experimentales en el campo del análisis de vibraciones se encuentran inevitablemente contaminadas con ruido. Este es proveniente de varias fuentes incluyendo condiciones medioambientales y aspectos propios ...
