Estimation of cellular traction forces in morphogenesis of capillaries through advanced material modeling of fibrous biopolymers
(Universitat Politècnica de Catalunya, 2022-02-07)
Treball Final de Grau
Accés obertVaculogenesis is a process during which endothelial cells grow to form a network of interconnected vessels, to provide oxygen and nutrients to surrounding tissues. Endothelial cells microenvironment has an important impact ... -
Estimation of crack opening from a two-dimensional continuum-based finite element computation
(2012-11)
Article
Accés obertDamage models are capable of representing crack initiation and mimicking crack propagation within a continuum framework. Thus, in principle, they do not describe crack openings. In durability analyses of concrete structures ... -
Estimation of cut-off points under complex-sampling design data
(Institut d'Estadística de Catalunya, 2022-06-02)
Article
Accés obertIn the context of logistic regression models, a cut-off point is usually selected to dichotomize the estimated predicted probabilities based on the model. The techniques proposed to estimate optimal cut-off points in the ... -
Estimation of directed effective connectivity from fMRI functional connectivity hints at asymmetries of cortical connectome
(Public Library of Science (PLOS), 2016-03-16)
Article
Accés obertThe brain exhibits complex spatio-temporal patterns of activity. This phenomenon is governed by an interplay between the internal neural dynamics of cortical areas and their connectivity. Uncovering this complex relationship ... -
Estimation of dispersion curves by combining effective elastic constants and SAFE method: a case study in a plate under stress
(Institute of Physics (IOP), 2017)
Article
Accés obertThis paper presents an approach to calculate dispersion curves for homogeneous and isotropic plates subject to stress, via Semi-Analytical Finite Element and the Effective Elastic Constants, since stresses in the waveguide ... -
Estimation of dynamic models using kernel density
(2002-08)
Comunicació de congrés
Accés restringit per política de l'editorialThe objective of this work is to present a simple approach to deal with a dynamic model without imposing any assumptions on the error distribution. Using a state-space representation the model does not need any optimization ... -
Estimation of electric vehicle battery capacity requirements based on synthetic cycles
(2023-01)
Article
Accés obertThe adoption of the Electric Vehicle requires a switch towards a circular system to reduce their environmental impact. Under this framework, the correct sizing of the batteries and avoiding their underuse are key actions. ... -
Estimation of Fekete points
(2005-05)
Article
Accés obertIn this paper we present a new method to estimate Fekete points on surfaces. Although our method works in a general setting, we concentrate on its application to the unit sphere because it is the prototype problem and ... -
Estimation of finite population distribution function with auxiliary information in a complex survey sampling
(Institut d'Estadística de Catalunya, 2022-06-02)
Article
Accés obertIn this paper, we consider the problem of estimating the finite population cumulative distribution function (CDF) in a complex survey sampling, which includes two-stage and three-stage cluster sampling schemes with and ... -
Estimation of flight CO2 emissions and travel time with analytical models
(2021)
Comunicació de congrés
Accés obertFlights negatively impact the environment and the aviation industry faces significant challenges to decarbonise. This is particularly relevant for short- and medium-haul flights, as operations in these ranges can be less ... -
Estimation of fuel consumption in a hybrid electric refuse collector vehicle using a real drive cycle
(IEEE Press, 2016)
Text en actes de congrés
Accés obert -
Estimation of fuel inefficiencies due to early descents
(Universitat Politècnica de Catalunya, 2018-10-30)
Treball Final de Grau
Accés obertIn this project, early descents have been modeled as a combination of two stages. Firstly, a constant - vertical - speed segment beginning at a certain distance, k , before the optimal top of descent (TOD); that eventually ... -
Estimation of future emission scenarios for analysing the impact of traffic mobility on a large Mediterranean conurbation in the Barcelona Metropolitan Area (Spain)
(2013-01-01)
Article
Accés obertEmission modelling permits us to quantitatively assess the effects of emission abatement strategies. In urban areas, such strategies are designed mainly to reduce the emissions from the on–road traffic sector. This work ... -
Estimation of future extreme rainfall in Barcelona (Spain) under monofractal hypothesis
(John Wiley & sons, 2023-03)
Article
Accés obertClimate change effects on subdaily rainfall (from 5¿min to a few hours) can hardly be measured in mid-latitude climates due to the high natural variability of the precipitation patterns and their effects on local topography. ... -
Estimation of granular flow impact force on rigid wall using material point method
(CIMNE, 2017)
Text en actes de congrés
Accés obertLandslides and avalanches cause loss of lives, as well as generate significant economic cost. Protection barriers help reduce the impact of such events. However, the design of the barriers requires the prediction of the ... -
Estimation of gravimetric vegetation moisture in the western United States using a multi-sensor approach
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Text en actes de congrés
Accés obertVegetation optical depth (VOD) depends on the water, structure, and biomass of vegetation. Here, we propose a multi-sensor approach to isolate the water component from the VOD and to retrieve gravimetric vegetation moisture ... -
Estimation of helicopter and target motion for teh advanced attack helicopter fire control system
(Universitat Politècnica de Barcelona. Centre de Càlcul, 1980-12)
Article
Accés obertThe problem of estimating helicopter and target motion for the Advanced Attack Helicopter tire control system is formulated using the Kalman-Bucy one-step predictor. Dynamic models for the helicopter and target were developed ... -
