Tecnologías avanzadas en la mecanización de la Agricultura Sostenible en Andalucía
(Consejo Social de la Universidad de Córdoba, 2009) -
Ternary Blends for Self-Compacting Mortars Production Composed by Electric Arc Furnace Dust and Other Industrial by-Products
(MDPI, 2022)This study is framed within the circular economy model through the valorisation of industrial by-products. This research shows the results of producing self-compacting mortars (SCMs) with electric arc furnace dust (EAFD) ... -
Testing Accuracy of Long-Range Ultrasonic Sensors for Olive Tree Canopy Measurements
(MDPI, 2015)Ultrasonic sensors are often used to adjust spray volume by allowing the calculation of the crown volume of tree crops. The special conditions of the olive tree require the use of long-range sensors, which are less ... -
Testing the Suitability of a Terrestrial 2D LiDAR Scanner for Canopy Characterization of Greenhouse Tomato Crops
(MDPI, 2016)Canopy characterization is essential for pesticide dosage adjustment according to vegetation volume and density. It is especially important for fresh exportable vegetables like greenhouse tomatoes. These plants are thin ... -
The contribution of fruit and leaves to the dynamic response of secondary branches of orange trees
(Elsevier, 2020)The current commercial technologies for mass harvesting fruit are based on the application of forced vibration to the tree, which is transmitted to the fruits causing their detachment. The dynamic behaviour of the plant ... -
The Effects of Port Water Injection on Spark Ignition Engine Performance and Emissions Fueled by Pure Gasoline, E5 and E10
(MDPI, 2020)It has been proven that vehicle emissions such as oxides of nitrogen (NOx) are negatively affecting the health of human beings as well as the environment. In addition, it was recently highlighted that air pollution may ... -
The Experimental Study of the Utilization of Recycling Aggregate from the Demolition of Elements of a Reinforced Concrete Hall
(MDPI, 2020)The article shows a case study as to whether the thermal and mechanical recycling of concrete is suitable for concrete debris from the demolition of structural elements of a 30-year-old industrial hall. The experiment ... -
The Influence of Heat and Mechanical Treatment of Concrete Rubble on the Properties of Recycled Aggregate Concrete
(MDPI, 2019)Concrete is a building material commonly used for ages. Therefore, in the result of repairs or demolition of building structures, large amounts of concrete rubble are created, which requires appropriate management. The aim ... -
The mechanical performance of recycled slate waste fiber composites based on unsaturated polyester resins
(MDPI, 2023)In the last few decades, there has been increasing social awareness for environmental conservation, which is driving the development of composite materials based on natural fibers. These new materials have interesting ... -
The Performance of Concrete Made with Secondary Products—Recycled Coarse Aggregates, Recycled Cement Mortar, and Fly Ash–Slag Mix
(MDPI, 2022)The properties of cement concrete using waste materials—namely, recycled cement mortar, fly ash–slag, and recycled concrete aggregate—are presented. A treatment process for waste materials is proposed. Two research experiments ... -
The role of pH on leaching of heavy metals and chlorides from electric arc furnace dust in cement-based mortars
(Elsevier, 2018)Electric arc furnace dust (EAFD) presents a pollution hazard due to its heavy metal leachability. Its characterization is essential for recovery or disposal in hazardous waste landfills. The present work discusses the ... -
The role of powder content of the recycled aggregates of CDW in the behaviour of rendering mortars
(Elsevier, 2019)In recent years, the number of studies on the incorporation of recycled aggregate (RA) into mortars has grown considerably. However, mixed recycled aggregate (MRA) is investigated on a much smaller scale due mainly to its ... -
The use of artificial intelligence for sign language recognition in education: from a literature overview to the ISENSE project
(IEEE, 2023)Common strategies to guarantee the inclusion of d/Deaf students in university are still absent. Recent studies have demonstrated how innovative technologies, such as artificial intelligence and virtual/augmented reality, ... -
The vibration behaviour of hedgerow olive trees in response to mechanical harvesting with straddle harvester
(Elsevier, 2019)Understanding tree behaviour under mechanical harvesting is very important for orchard management and machine design. The objective of this work is to determine the Dynamic response of trees, in a hedgerow arrangement, to ... -
Towards an Optimized Method of Olive Tree Crown Volume Measurement
(MDPI, 2015)Accurate crown characterization of large isolated olive trees is vital for adjusting spray doses in three-dimensional crop agriculture. Among the many methodologies available, laser sensors have proved to be the most ... -
Training program on sign language: social inclusion through Virtual Reality in ISENSE project
(IEEE, 2023)Structured hand gestures that incorporate visual motions and signs are used in sign language. Sign language is a valuable means of daily communication for individuals who are deaf or have speech impairments, but it is ... -
Tuberculosis and Other Airborne Microbes in Occupational Health and Safety
(MDPI, 2020)Airborne pathogens and non-malignant infectious diseases such as tuberculosis are highly contagious and can have severe effects on healthcare workers. The symptoms of these diseases take time to manifest, which can prevent ... -
Understanding why women don’t choose engineering degrees
(Springer Nature, 2019)Despite the continuous efforts of governments and universities to avoid the underrepresentation of women entering engineering degrees, the trend has not reverted, and this is a general fact all over the world. This fact ... -
