Dual-Signal Transmission Using RF Precoding and Analog Beamforming With TMAs
(Institute of Electrical and Electronics Engineers, 2018)[Abstract]: Time-modulated arrays (TMAs) receiving beamforming provide a noteworthy hardware simplicity given the ability of this multi-antenna technique to transform spatial diversity into frequency diversity. However, ... -
Dualgrid : a closed representation space for consistent spatial databases
(2012)[Abstract] In the past decades, much effort has been devoted to the integration of spatial information within more traditional information systems. To support such integration, spatial data representation technology has ... -
Dunaliella salina as marine microalga highly tolerant to but a poor remover of cadmium
(2009-06)[Abstract]Cadmium tolerance and removal in the marine microalga Dunaliella salina were studied in cultures exposed to different metal concentrations (5–120 mg Cd l−1) for 96 h. This microalga can be included in the group ... -
Durabilidad de las mezclas bituminosas elaboradas con RCD
(Asociación Española de la Carretera, 2010)[Resumen:] En esta comunicación se analiza el efecto del agua sobre la durabilidad de mezclas bituminosas en caliente fabricadas con áridos reciclados de residuos de construcción y demolición. Con el fin de evaluar este ... -
Durability of Eco-Efficient Binary Cement Mortars Based on Ichu Ash: Effect on Carbonation and Chloride Resistance
(Elsevier, 2022)[Abstract] This research work focuses on the performance of mortars containing ichu ash as a potential environmentally-sound alternative to traditional pozzolans (at 6% and 10% replacement levels) under CO2 and chloride ... -
Durability of joints made with threaded steel rods glued in chestnut timber. An experimental approach
(Elsevier, 2017)This paper presents the results of an experimental study developed on joints made with glued-in rods in glued laminated chestnut, with the rods inserted parallel to the grain. Three anchor lengths have been used. The test ... -

Dynamic analysis of school mobility using geolocation web technologies
(MDPI, 2023)[Abstract:] Pedestrian travel represents one of the most complex forms of mobility owing to the numerous parameters that influence its analysis and the difficulty of acquiring accurate travel information. In addition, the ... -
Dynamic calculation of breakwater crown walls under wave action: influence of soil mechanics and shape of the loading state
(MDPI, 2019)[Abstract:] As a consequence of the action of waves on rubble mound breakwaters, there are loads—both on the vertical and horizontal sides of the crown walls—which modify the conditions of their stability. These loads ... -
Dynamic Malware Mitigation Strategies for IoT Networks: A Mathematical Epidemiology Approach
(MDPI, 2024-01-12)[Abstract] With the progress and evolution of the IoT, which has resulted in a rise in both the number of devices and their applications, there is a growing number of malware attacks with higher complexity. Countering the ... -
Dynamic rheological comparison of silicones for podiatry applications
(Elsevier, 2018-05-26)[Abstract]: This work shows an effective methodology to evaluate the dynamic viscoelastic behavior of silicones for application in podiatry. The aim is to characterize, compare their viscoelastic properties according to ... -
Dynamic Simulation Applied to Refinery Hydrogen Networks
(Servicio de Publicaciones de la Universidad de Oviedo, 2017)[Abstract] This study analyses the usefulness of process network dynamics simulation for decision-making in refinery hydrogen networks. A theoretical hydrogen network of three desulphurisation plants is modelled, and three ... -
Dynamic update of flow and transport parameters in reactive transport simulations of radioactive waste repositories
(Elsevier, 2020)[Abstract:] The changes in porosity caused by mineral dissolution/precipitation and the associated changes in flow, transport and chemical parameters of porous and fractured media are relevant for the geochemical time-evolution ... -
Dynamical Study of a Moored Vessel Using Computer Vision
(Springer, 2018)[Abstract]: Wind and wave effects have a major impact on the design of mooring and anchoring systems, whose purpose is to prevent the movement of the cargo and the moored ship while optimizing the operations which have to ... -
