Publicación Acceso Abierto Implementing transfer learning for sound event classification using the realised audio database(Elsevier, 2025-01-04) Mohíno Herranz, Inmaculada; García Gómez, Joaquín; Alonso Díaz, Sagrario; García Gallegos, Jaime; Perez Sanz, Fernando; Aguilar Ortega, Miguel; Gil Pita, Roberto; Agencia Estatal de Investigación (España); Comunidad de MadridCurrently, smart spaces utilize diverse sensors to gather real-time data on activities within environments, enabling systems to activate alarms or execute tasks. These environments support various applications integrating advanced sensory systems like cameras, microphones, and motion sensors. Acoustic sensors are crucial, extracting valuable information from sound waves, including source details and environment characteristics. This article focuses on detecting and classifying common household sounds using the ReaLISED database, comprising 2479 recordings of 18 events. Audio data were collected in real homes with everyday objects and activities, unlike reverberation models. Artificial Intelligence techniques, including Machine Learning classifiers, yielded satisfactory outcomes. Transfer Learning methods were explored, leveraging pre-trained models like YAMNet for sound event recognition by Google, potentially outperforming previous classifiers. Preliminary results reveal a relative reduction of around 25 % in the probability error rate when comparing the obtained results with previous studies, providing valuable insights into potential possibilities and enhancements.Publicación Acceso Abierto Digital transformation: Ensuring metrological traceability(Elsevier, 2024-12-27) Benyon Puig, Robert; García Gallegos, Jaime; Mohíno Herranz, Inmaculada; Perez Sanz, Fernando; Vicente Mussons, TomásThe digital transformation project for the calibration and testing laboratories of INTA is presented. It is intended to serve as the institute's single platform for integrating knowledge, capabilities and innovative metrology techniques, quality and testing systems, to produce highly efficient and reliable results while ensuring metrological traceability of R + D + i results. It provides the necessary data for decision support and aims to address many current issues faced by laboratories and testing centres. The project is developed across the following action areas: (a) Automation of quality assurance for measurements according to ISO/IEC 17043 standard; (b) Automation of data capture and analysis of calibration procedures for the Metrology and Calibration Centre (CMC) and various tests; (c) Digital services for remote auditing of measurement and testing services in accordance with ISO/IEC 17025 and ISO/IEC 17043 standards; (d) Evolution towards the flexibility and expansion of parameterization of the different modules to facilitate implementation in any type of INTA and Ministry of Defence (MoD) laboratories.Publicación Acceso Abierto Digitalization of a calibration laboratory: Batch calibration(Elsevier, 2024-12-22) Perez Sanz, Fernando; Larroca Sanz, Rebeca; Mohíno Herranz, Inmaculada; García Gallegos, Jaime; Vicente Mussons, Tomás; Benyon Puig, RobertThe Metrology and Calibration Centre (CMC) at the National Institute of Aerospace Technology (INTA) has introduced an innovative tool designed to enhance the efficiency and effectiveness of calibration processes within its facilities. This cutting-edge software enables technicians to conduct multiple calibrations simultaneously, provided the requisite experimental setup is in place. Developed with a focus on streamlining the entire calibration workflow, from data acquisition to certificate issuance, the software ensures compliance with the ISO/IEC 17025 standard. Through rigorous testing, the CMC verified the software's performance using devices employed for monitoring ambient conditions (temperature and humidity) across various INTA test laboratories. Notably, these devices underwent batch calibration in groups of six, resulting in a sixfold reduction in experimentation time. Although the associated paperwork was reduced, the necessity to maintain traceability and issue individual calibration certificates for each device offsets the time savings.Publicación Acceso Abierto Digitalization of on-site characterization of climatic chambers(Elsevier, 2024-12-27) García Gallegos, Jaime; Benyon Puig, Robert; Perez Sanz, Fernando; Mohíno Herranz, Inmaculada; Vicente Mussons, TomásThe implementation of a software tool applied to the characterization of climatic chambers is presented and discussed. INTA took part in the design and development of the algorithms for the automatic identification of stabilization periods of physical parameters measured based on defined acceptance criteria and the application of mathematical and statistical analysis for the interpretation of the results obtained. The new operational procedure implemented at INTA is presented as an innovation in the service offered by the laboratory to its clients, allowing them to improve the efficiency of their production processes. It enables the remote calibration of climatic chambers and other thermal facilities of the Institute in different locations in Spain, without the need to move calibration technicians, resulting in increased efficiency in the use of human resources and cost savings.
