Ocupación y transformación del suelo de las carreteras españolas
Asociación Española de Dirección e Ingeniería de Proyectos (AEIPRO) (2008)The term ‘land use’ is traditionally used to denote a classification of human activities which occupy land area. In the field of Life Cycle Assessment (LCA), the terms ‘land use’ or ‘land use impact’ have been used to ... -
On the basic phenomenon of soil-structure interaction on the free vibration response of beams : Application to railway brigdes
Elsevier (2016-10)The dynamic transverse response of beam type bridges under railway traffic is addressed in this contribution. In particular, how soil-structure interaction may affect the critical or resonant velocities and the associated ... -
On the effects of the fix geometric constraint in 2D profiles on the reusability of parametric 3D CAD models
Springer-Verlag (2018-06)In order to be reusable, history-based feature-based parametric CAD models must reliably allow for modifications while maintaining their original design intent. In this paper, we demonstrate that relations that fix the ... -
On the Existence of a Progressive Variational Vademecum based on the Proper Generalized Decomposition for a Class of Elliptic Parameterized Problems
Elsevier (2018-03)In this study, we present the mathematical analysis needed to explain the convergence of a progressive variational vademecum based on the proper generalized decomposition (PGD). The PGD is a novel technique that was developed ... -
On the Internationalization of CAD Learning Through an English Glossary
Springer (2020-03-10)The internationalization of higher education is an essential factor to improve the quality and efficiency of Spanish universities, providing students with the main skills, and knowledge to interact effectively in an ... -
On the One-Dimensional Modeling of Vertical Upward Bubbly Flow
Hindawi Publishing Corporation (2018)The one-dimensional two-fluid model approach has been traditionally used in thermal-hydraulics codes for the analysis of transients and accidents in water–cooled nuclear power plants. This paper investigates the performance ... -
On the relationship between the specific heat enhancement of salt-based nanofluids and the ionic exchange capacity of nanoparticles
Nature Publishing Group (2018)Nanoparticles have been used in thermal applications to increase the specific heat of the molten salts used in Concentrated Solar Power plants for thermal energy storage. Although several mechanisms for abnormal enhancement ... -
On the Role of Geometric Constraints to Support Design Intent Communication and Model Reusability
CAD Solutions (2020)The assurance of model quality in parametric CAD implies that designers must build models that facilitate reuse while retaining their design intent when modified. In this context, a suitable selection of geometric constraints ... -
On the use of area-averaged void fraction and local bubble chord length entropies as two- phase flow regime indicators
Springer Verlag (2010)In this work, the use of the area-averaged void fraction and bubble chord length entropies is introduced as flow regime indicators in two-phase flow systems. The entropy provides quantitative information about the disorder ... -
On the use of deep learning and computational fluid dynamics for the estimation of uniform momentum source components of propellers
Cell Press (2023-12)This article proposes a novel method based on Deep Learning for the resolution of uniform momentum source terms in the Reynolds-Averaged Navier-Stokes equations. These source terms can represent several industrial devices ... -
On the vertical coupling effect of ballasted tracks in multi–span simply–supported railway bridges under operating conditions
Routledge (2022)This contribution investigates the vertical coupling exerted by ballasted tracks on the vertical response of bridges composed either of (i) several successive simply-supported spans with weak coupling between them due to ... -
On-site real-time evaluation of an air-conditioning direct-fired double-effect absorption chiller
Elsevier (2009)This work presents a procedure for calculating the COP and heat transfer rates, based on on-site experimental temperature measurements, of a lithium-bromide/water direct-fired double-effect absorption chiller in reverse ... -
On-site study of HCFC-22 substitution for HFC non-azeotropic blends (R417A, R422D) on a water chiller of a centralized HVAC system
Elsevier (2010)The European Regulation no 2037/2000 has banned manufacturing HCFC refrigerants from January 1st 2010, although its use is allowed up to 2015 if the fluids come from a recycling process. This situation creates the need for ... -
Ontología hermenéutica para la creación de alternativas de diseño
Asociación Española de Dirección e Ingeniería de Proyectos (AEIPRO) (2009)In the field of creativity, different techniques have been used for the problem resolution. It has to be emphasized brainstorming, mind maps, TRIZ (Theory of Resolution of Inventive Problems), and so on. For that, it ... -
Opciones de valorización de lodos de distintas estaciones depuradoras de aguas residuales
Universidad Autónoma de Yucatán. Facultad de Ingeniería (2010-09)La legislación actual en la Unión Europea recomienda que los lodos de depuradora de aguas residuales se utilicen como fertilizante. Sin embargo, la presencia de metales pesados puede limitar esta aplicación, lo cual es ... -
Optical characterisation and photothermal conversion efficiency of a water-based carbon nanofluid for direct solar absorption applications.
Elsevier (2020-12-01)Carbon nanoparticles are very useful in solar thermal applications as they absorb much of the solar spectrum and can be inexpensive. Water-based carbon nanofluids with two different concentrations (3 and 33 mg l−1) were ... -
Optical characterisation of oxidised carbon nanohorn nanofluids for direct solar energy absorption applications
Elsevier (2019-10-31)Carbon nanohorns and oxidised carbon nanohorns-based nanofluids were characterised by taking one step forward. The advantage of studying oxidised carbon nanohorns is that they are surfactant-free. The stability of both ... -
