• #### A mixed three-field FE formulation for stress accurate analysis including the incompressible limit ﻿

(2015-01)
Article
Open Access
In previous works, the authors have presented the stabilized mixed displacement/pressure formulation to deal with the incompressibility constraint. More recently, the authors have derived stable mixed stress/displacement ...
• #### A mixed-signal architecture for high complexity CMOS fuzzy controllers ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Article
Open Access
Analog circuits provide better area/power efficiency than their digital counterparts for low-medium precision requirements [1]. This limit in precision, as well as the lack of design tools when compared to the digital ...
• #### A mobile robotic platform capable of stereo vision based on blod detection ﻿

(Universitat Politècnica de Catalunya, 2014-12)
Master thesis (pre-Bologna period)
Open Access
In robotics, vision is an indispensable tool. It is used for a wide spectrum of applications, such as Simultaneous Localization And Mapping (SLAM), object recognition and communication. Vision is expensive both in terms ...
• #### A mobile Scenario for Electronic Publishing based on the MIPAMS Architecture ﻿

(2011)
Conference report
Open Access
This paper describes several scenarios for the management of digital media, focusing on electronic publishing from mobile environments. The solution proposed in those scenarios is based on MIPAMS (Multimedia Information ...
• #### A model and an algorithm for the grouping problem in telecom networks ﻿

(Universitat Politècnica de Catalunya. Centre de Càlcul, 1991)
Article
Open Access
This paper deals with the so called grouping problem which arises in telecommunication network optimization when transmission equipment with a certain hierarchy is used. It is shown how this problem is embedded in the ...
• #### A model for CAGD using fuzzy logic ﻿

(1997-01)
Article
Restricted access - publisher's policy
This paper presents a first approach to a system based on fuzzy logic for the design of curves and surfaces in the context of computer aided geometric design. Bézier curves and surfaces can be seen as particular cases of ...
• #### A model for credit scoring: an application of discriminant analysis ﻿

Article
Open Access
The application of statistical techniques in decision making, and more specifically for classification requirements, has proved to be adequate in the context of financial problems. In this study, we present the methodology ...
• #### A model for estimating the impact of the domino effect on accident frequencies in quantitative risk assessments of storage facilities ﻿

(2013-11)
Article
Restricted access - publisher's policy
It is well known that the domino effect can have a major impact on accidents in storage facilities, as it can increase the consequences of an initial event considerably. However, quantitative risk assessments (QRAs) do not ...
• #### A model for grain-size sorting over tidal sand ridges ﻿

(2004-07)
Article
Restricted access - publisher's policy
A model was developed and analyzed to quantify the effect of graded sediment on the formation of tidal sand ridges. Field data reveal coarse (fine) sediment at the crests (in the troughs), but often phase shifts between ...
• #### A model for Janus and Epimetheus ﻿

(Universitat Politècnica de Catalunya, 2015-10)
Bachelor thesis
Open Access
In this work we present a model that tries to fit the behaviour of Janus and Epimetheus, two co-orbital moons of Saturn. This has been done before using the model for the two-dimensional restricted three-body problem, and ...
• #### A model for non-free circle actions ﻿

(1997)
Article
Open Access
Let $\Phi: \Bbb S^{1}\times M\longrightarrow M$ be a smooth action of the unit circle $\Bbb S^{1}$ on a manifold $M$. In this work, we compute the minimal model of $M$ in terms of the orbit space $B$ and the fixed point ...
• #### A model for opinion agreement and confidence in multi-expert multi-criteria decision making ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2004)
Article
Open Access
In multi-expert multi-criteria decision making problems, we often have to deal with different opinions, different importance of criteria and experts, missing data, unexpressed opinions and experts who are not fully ...
• #### A model for railway induced ground vibrations in the frame of preliminary assessment studies ﻿

(Universitat Politècnica de Catalunya, 2007-07-13)
Doctoral thesis
Open Access
• #### A model for revocation forecasting in public-key infrastructures ﻿

(2015-05-01)
Article
Open Access
One of the hardest tasks of a certification infrastructure is to manage revocation. This process consists in collecting and making the revocation status of certificates available to users. Research on this topic has focused ...
• #### A model for rockill compressibility ﻿

(Institution of Civil Engineers (http://www.ice.org.uk/), 2001)
Article
Open Access
The paper presents a macroscopic constitutive model for rockill that includes the effect of water on compressibility and collapse phenomena. Breakage of rock particles and fracture propagation are basic underlying mechanisms ...
• #### A model for sand ridges on the shelf: effect of tidal and steady currents ﻿

(2001-05)
Article
Open Access
The dynamics of sand ridges, as observed on the innershelves and midshelves of various coastal seas, are investigated within the framework of an idealized model. These seabed undulations include shoreface-connected sand ...
• #### A Model for the analysis of concrete dams due to environmental thermal effects ﻿

(Emerald, 1996)
Article
Open Access
In this article, an analytical model is presented for the simulation of the thermal behavior of dams that are subjected to the environmental thermal action during service. The method of solution adopted as well as the ...
