Thermal expansion behaviour of Invar 36 alloy parts fabricated by wire-arc additive manufacturing
Invar 36 alloy is of high interest in various industrial sectors, due to its reduced thermal expansion properties. This study aims to validate Wire-Arc Additive Manufacturing (WAAM) technology as a valid method for ... -
Thermoelectric heat recovery in a real industry: from laboratory optimization to reality
Thermoelectricity, in the form of thermoelectric generators, holds a great potential in waste heat recovery, this potential has been studied and proved in several laboratory and theoretical works. By the means of a ... -
Three-dimensional finite element modelling of sheet metal forming for the manufacture of pipe components: symmetry considerations
The manufacture of parts by metal forming is a widespread technique in sectors such as oil and gas and automotives. It is therefore important to make a research effort to know the correct set of parameters that allow the ... -
Tomography analysis of Al-Mg alloys manufactured by wire-arc directed energy deposition with different metal transfer modes
The interest in aluminum-magnesium alloy additive manufacturing through Wire-arc Directed Energy Deposition (DED) technology has substantially grown in recent years. The main challenge in additive manufactured aluminum-magnesium ... -
Topological features dictate the mechanics of the mammalian brains
Understanding brain mechanics is crucial in the study of pathologies involving brain deformations such as tumor, strokes, or in traumatic brain injury. Apart from the intrinsic mechanical properties of the brain tissue, ... -
The transformation of a trade fair and exhibition centre into a field hospital for COVID-19 patients via multi-utility tunnels
This article exposes, through the case study of the IFEMA trade fair and exhibition centre in Madrid (Spain), the benefits of using a multi-utility tunnels (MUTs) system as a smart and sustainable solution for the distribution ... -
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. ... -
Triaxial accelerometer based azimuth estimator for horizontal axis wind turbines
One of the elements that receives the greatest stresses is the main shaft. Its damage is directly related to the cyclical nature of its rotational motion. However, the vast majority of horizontal axis wind turbines (HAWT) ... -
Ultra-low frequency multidirectional harvester for wind turbines
In this paper we propose, and demonstrate through a prototype, a completely novel device able to harvest mechanical energy from the multidirectional vibrations in a wind turbine, and convert it into electrical, to power ... -
Ultraviolet erythemal irradiance (UVER) under different sky conditions in Burgos, Spain: multilinear regression and artificial neural network models
Different strategies for modeling Global Horizontal UltraViolet Erythemal irradiance (GHUVE) based on meteorological parameters measured in Burgos (Spain) have been developed. The experimental campaign ran from September ... -
A unified analytical disk cam profile generation methodology using the Instantaneous Center of Rotation for educational purpose
Cam design is a fundamental part of the Mechanism and Machine Theory (MMT) and is included in the vast majority of MMT books. Cam profile design is usually determined with graphical and analytical methods. Graphical methods ... -
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 ... -
Use of computational fluid dynamics to compare upper airway pressures and airflow resistance in brachycephalic, mesocephalic, and dolichocephalic dogs
Brachycephalic dog breeds are prone to breathing difficulties because of their upper airway anatomy. Several surgical techniques exist to correct anatomical pathologies and common surgical approaches aim to correct functional ... -
Using a coupled dynamic factor-random forest analysis (DFRFA) to reveal drivers of spatiotemporal heterogeneity in the semi-arid regions of southern Africa
Understanding the drivers of large-scale vegetation change is critical to managing landscapes and key to predicting how projected climate and land use changes will affect regional vegetation patterns. This study aimed to ... -
Using a fuzzy inference system to obtain technological tables for electrical discharge machining processes
Technological tables are very important in electrical discharge machining to determine optimal operating conditions for process variables, such as material removal rate or electrode wear. Their determination is of great ... -
Validation and calibration of models to estimate photosynthetically active radiation considering different time scales and sky conditions
Photosynthetically Active Radiation (PAR) is a fundamental parameter for developing plant productivity models. Nevertheless, instrumentation for measuring PAR and to record it is scarce at conventional meteorological ... -
