(2016-12-01)
Article
Accés restringit per decisió de l'autor
The difficult current environmental situation, caused by construction industry residues containing ceramic materials, could be improved by using these materials as recycled aggregates in mortars, with their processing ...
• #### An experimental study of multi-radio platform coexistence in the 5 GHz band for railway applications ﻿

(Springer Verlag, 2011)
Text en actes de congrés
Accés restringit per política de l'editorial
This paper studies the practical challenges that arise due to the coexistence of two wireless technologies, both operating in the license-exempt 5 GHz band. In particular, WiFi and WiMAX equipment have been used in the ...
• #### An experimental study of the minimum linear colouring arrangement problem ﻿

(Universitat Politècnica de Catalunya, 2017-07)
Treball Final de Grau
Accés obert
The Minimum Linear Colouring Arrangement problem (MinLCA) is a variation from the Minimum Linear Arrangement problem (MinLA) and the Colouring problem. The objective of our problem is finding the best proper colouring of ...
• #### An experimental study of ultrasonic vibration and the penetration of granular material ﻿

(2017-02-01)
Article
Accés obert
This work investigates the potential use of direct ultrasonic vibration as an aid to penetration of granular material. Compared with non-ultrasonic penetration, required forces have been observed to reduce by an order of ...
• #### An experimental study on the compaction and collapsible behaviour of a flood defence embankment fill ﻿

(2014-09)
Article
Accés restringit per acord de confidencialitat
With renewed interest in the performance of flood embankments globally, it is important that the performance of fills in conditions similar to 'as-constructed' are scrutinised. The fill material investigated in this study ...
• #### An experimental study on the effects of shading in 3D perception of volumetric models ﻿

(Springer, 2017-01)
Article
Accés restringit per política de l'editorial
Throughout the years, many shading techniques have been developed to improve the conveying of information in volume visualization. Some of these methods, usually referred to as realistic, are supposed to provide better ...
• #### An experiment of planning manual work taking account of learning and forgetting ﻿

(Universitat Politècnica de Catalunya, 2007-06-29)
Projecte/Treball Final de Carrera
Accés obert
Avui en dia, les indústries es troben exposades freqüentment a canvis en el volum de producció, en els productes que es fabriquen i a canvis de tecnologies als processos que desenvolupen, per tal de millorar la productivitat. ...
• #### An Experiment on automatic semantic tagging of dictionary senses ﻿

(1995-06)
Report de recerca
Accés obert
We present a methodology to enrich a dictionary sense with semantic tags. The method relies on the use of a wide-coverage noun taxonomy and the notion of conceptual distance among concepts. Some experimental results about ...
• #### An experiment on task performance forecasting based on the experience of different tasks ﻿

(2007-09-15)
Article
Accés obert
Performance in a task is influenced not only by the experience obtained in doing this task, but by how recent it is and by the experience obtained in doing similar tasks. Competence-Performance Approach is used as the ...
• #### An explanatory model of the organisational factors that explain the adoption of e-business ﻿

(2016-06)
Article
Accés obert
Purpose: To describe the factors that facilitate the adoption of e-business in firms. To go in deep on the factors, resources and capabilities that need to be present in those firms seeking to improve their levels of ...
• #### An explicit construction for neighborly centrally symmetric polytopes ﻿

(2006-06-29)
Article
Accés obert
We give an explicit construction, based on Hadamard matrices, for an infinite series of $\big\lfloor\frac12\sqrt{d}\big\rfloor$-neighborly centrally symmetric $d$-dimensional polytopes with $4d$~vertices. This ...
• #### An explicit expression of the first Liapunov and period constants with applications ﻿

(1996)
Article
Accés obert
In this paper, we study systems in the plane having a critical point with pure imaginary eigenvalues, and we search for effective conditions to discern whether this critical point is a focus or a center; in the case of it ...
