Gaseous fueling of an adapted commercial automotive spark-ignition engine: simplified thermodynamic modeling and experimental study running on hydrogen, methane, carbon monoxide and their mixtures
In the present work, methane, carbon monoxide, hydrogen and the binary mixtures 20 % CH4–80 % H2, 80 % CH4–20 % H2, 25 % CO–75 % H2 (by volume) were considered as fuels of a naturally aspirated port-fuel injection four-cylinder ... -
Parametric modelling of 3D printed concrete segmented beams with rebars under bending moments
3D concrete printing is gaining relevance as a technology for the manufacture of lightweight components and complex freeform shells. Nevertheless, the insertion of reinforcing elements to withstand tensile stress, the ... -
Effects of climate change on streamflow and nitrate pollution in an agricultural mediterranean watershed in northern Spain
Predicting water quality and quantity response to climate change in a watershed is very difficult due to the complexity and uncertainties in estimating and understanding future hydrological conditions. However, hydrological ... -
Evaluation of the impact of changing from rainfed to irrigated agriculture in a mediterranean watershed in Spain
The conversion of cultivated areas from rainfed to irrigated agriculture alters the watershed’s hydrology and could affect the water quality and quantity. This study examined how streamflow, nitrate load, and nitrate ... -
Setting a comprehensive strategy to face the runback icing phenomena
The development of anti-icing robust surfaces is a hot topic nowadays and particularly crucial in the aeronautics or wind energy sectors as ice accretion can compromise safety and power generation efficiency. However, the ... -
Multi-objective optimization of tool wear, surface roughness, and material removal rate in finishing honing processes using adaptive neural fuzzy inference systems
Honing processes are usually employed to manufacture combustion engine cylinders and hydraulic cylinders. Honing provides a crosshatch pattern that favors the oil flow. In this paper, Adaptive Neural Fuzzy Inference System ... -
On the extension of k-ω-SST corrections to predict flow separation on thick airfoils with leading-edge roughness
Modern wind turbines employ thick airfoils in the outer region of the blade with strong adverse pressure gradients and high sensitivity to flow separation, which can be anticipated by leading-edge roughness. However, ... -
Study of effect of nickel content on tribocorrosion behaviour of nickel-aluminium-bronzes (NABs)
The simultaneous existence of mechanical erosion and electrochemical corrosion is a common scenario for engineering alloys used in marine environments, such as pump impellers and valves. Nickel–aluminium–bronzes (NABs) are ... -
Automatic trajectory determination in automated robotic welding considering weld joint symmetry
The field of inspection for welded structures is currently in a state of rapid transformation driven by a convergence of global technological, regulatory, and economic factors. This evolution is propelled by several key ... -
Linear uncertain modelling of LIDAR systems for robust wind turbine control design
Light detection and ranging (LIDAR) sensors measure the free wind ahead of the rotor, enabling the use of new feedforward control strategies. However, there exist some sources of error inherent to the measuring process that ... -
Urban cooling potential and cost comparison of heat mitigation techniques for their impact on the lower atmosphere
Cool materials and rooftop vegetation help achieve urban heating mitigation as they can reduce building cooling demands. This study assesses the cooling potential of different mitigation technologies using Weather Research ... -
Evaluation of soil moisture estimation techniques based on Sentinel-1 observations over wheat fields
Soil moisture (SM) is a key variable in agriculture and its monitoring is essential. SM determines the amount of water available to plants, having a direct impact on the development of crops, on the forecasting of crop ... -
A comparative study in the design of TIO2 assisted photocatalytic coatings monitored by controlling hydrophilic behavior and rhodamine b degradation
This work presents a comparative study related to the photocatalytic efficiency associated with wettability measurements and organic dye degradation, as well as other relevant properties (i.e., corrosion resistance, ... -
Modeling of surface roughness in honing processes by using fuzzy artificial neural networks
Honing processes are abrasive machining processes which are commonly employed to improve the surface of manufactured parts such as hydraulic or combustion engine cylinders. These processes can be employed to obtain a ... -
Dynamic prediction of effective runoff sediment particle size for improved assessment of erosion mitigation efficiency with vegetative filter strips
The most widely implemented mitigation measure to reduce transfer of surface runoff pesticides and other pollutants to surface water bodies are vegetative filter strips (VFS). The most commonly used dynamic model for ... -
Trayectorias de máxima rigidez de un robot redundante actuando como soporte en el mecanizado de paredes delgadas
La precisión de un robot está ligada a su rigidez. En comparación con la máquina herramienta tradicional, los robots industriales tienen un gran espacio de trabajo como ventaja, pero una rigidez reducida como desventaja. ... -
