• #### A mixed Lagrangian and Eulerian FSI approach for simulation of overtopping on embankment dams ﻿

(CIMNE (Centro Internacional de Métodos Numéricos en Ingeniería), 2009)
Conference report
Open Access
The present work is concerned with some recent advances in FSI simulations with particular emphasis on the simulation of rockfill dams during extreme phenomena. The final objective is the study of the consequences of an ...
• #### A mixed qualitative quantitative self-learning classification technique applied to situation assessment in industrial process control ﻿

Doctoral thesis
Open Access
• #### A mixed stabilized finite element formulation for strain localization analysis ﻿

(2010)
Conference report
Open Access
This work exploits the concept of stabilization techniques to improve the behaviour of either mixed or pu/mixed u/εlinear/linear triangular elements when strain localization analysis is required. Different stabilization ...
• #### 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 ﻿

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 ...
