Diseño y construcción de un sistema digital avanzado de comunicaciones en HF
Andújar Márquez, José Manuel
; Pijoan i Vidal, J. Lluis (Universidad Complutense de Madrid, 2000)
Las investigaciones en el campo de la HF (3-30 MHz) fueron prácticamente inexistentes durante las décadas de los 60 y 70. En estos años, la comunidad científica apostó por los sistemas basados en los satélites debido a que ... -
A New and Inexpensive Pyranometer for the Visible Spectral Range
Martínez Bohórquez, Miguel Ángel; Andújar Márquez, José Manuel; Enrique Gómez, Juan Manuel (MDPI, 2009)
This paper presents the design, construction and testing of a new photodiode-based pyranometer for the visible spectral range (approx. 400 to 750 nm), whose principal characteristics are: accuracy, ease of connection, ... -
A New Automatic System for Angular Measurement and Calibration in Radiometric Instruments
Andújar Márquez, José Manuel; Martínez Bohórquez, Miguel Ángel; Medina García, Jonathan; Aguilar Nieto, Francisco José (MDPI, 2010)
This paper puts forward the design, construction and testing of a new automatic system for angular-response measurement and calibration in radiometric instruments. Its main characteristics include precision, speed, resolution, ... -
A New Metre for Cheap, Quick, Reliable and Simple Thermal Transmittance (U-Value) Measurements in Buildings
Andújar Márquez, José Manuel; Martínez Bohórquez, Miguel Ángel (MDPI, 2017)
This paper deals with the thermal transmittance measurement focused on buildings and specifically in building energy retrofitting. Today, if many thermal transmittance measurements in a short time are needed, the current ... -
Integration of Sensors, Controllers and Instruments Using a Novel OPC Architecture
González, Isaías; Calderón, Antonio José; Barragán Piña, Antonio Javier; Andújar Márquez, José Manuel (MDPI, 2017-06-27)
The interconnection between sensors, controllers and instruments through a communication network plays a vital role in the performance and effectiveness of a control system. Since its inception in the 90s, the Object Linking ... -
Hardware/Software Data Acquisition System for Real Time Cell Temperature Monitoring in Air-Cooled Polymer Electrolyte Fuel Cells
This work presents a hardware/software data acquisition system developed for monitoring the temperature in real time of the cells in Air-Cooled Polymer Electrolyte Fuel Cells (AC-PEFC). These fuel cells are of great interest ... -
Precise measurement of near-barrier 8He+208Pb elastic scattering : comparison with 6He
Marquínez Durán, Gloria; Martel Bravo, Ismael; Sánchez Benítez, Ángel Miguel; Acosta Sánchez, Luis Armando; Berjillos Morente, Rafael; Dueñas Díaz, José Antonio; Flores Garrido, Juan Luis; Abou-Haidar, Z. (American Physical Society, 2016)
Dramatic differences in the elastic scattering of the neutron rich nuclei 6He and 8He are found when new high quality data for the 8He+208Pb system are compared with previously published 6He+208Pb data at the same laboratory ... -
Easy Handling of Sensors and Actuators over TCP/IP Networks by Open Source Hardware/Software
Mejías Borrero, Andrés Manuel; Sánchez Herrera, María Reyes; Márquez Sánchez, Marco Antonio; Calderon Godoy, Antonio José; González, Isaías; Andújar Márquez, José Manuel (MDPI, 2017)
There are several specific solutions for accessing sensors and actuators present in any process or system through a TCP/IP network, either local or a wide area type like the Internet. The usage of sensors and actuators ... -
Prediction of cloudiness in short time periods using techniques of remote sensing and image processing
Alonso, Joaquín; Ternero, Antonio; Batlles, Francisco J.; López Rodríguez, Gabriel; Rodríguez, Jorge; Burgaleta, Juan I. (Elsevier, 2014)
In this work we introduce a methodology which enables to predict the cloudiness in the short and medium termanywhere in the world. Satellite images (Meteosat of Second Generation) are used in combination with images from ... -
