    • LED lamp modelling for harmonic studies in distribution systems 

      Molina, Julio; Mesas García, Juan José; Mesbahi, Nadhir; Sainz Sapera, Luis (2017-03-09)
      Article
      Accés restringit per decisió de l'autor
      Energy saving policies have boosted the use of light emitting diode (LED) lamps in distribution networks. These lamps are non-linear loads which inject harmonic currents into the distribution system, which has led to a ...
    • Shear strength degradation in claystones due to environmental effects 

      Pineda Jiménez, Jubert Andrés; Romero Morales, Enrique Edgar; De Gracia, Manuel; Sheng, Daichao (Thomas Telford, 2014-05)
      Article
      Accés restringit per política de l'editorial
      This note explores the influence of environmental effects, as those induced by cyclic changes in relative humidity, on the degradation of the shear strength parameters in Lilla claystone, a low-porosity clayey rock from ...
    • Small strain shear moduli of unsaturated natural and compacted loess 

      Ng, C. W. W.; Kaewsong, R.; Zhou, C.; Alonso Pérez de Agreda, Eduardo (Thomas Telford, 2017-07)
      Article
      Accés obert
      Suction and microstructure play critical roles in the mechanical behaviour of loess, yet their effects on small strain (from 0·001 to 1%) shear moduli are not fully understood. In this study, shear moduli of loess with ...
    • Swelling behaviour of compacted Maryland clay under different boundary conditions 

      Yuan, Shengyang; Buzzi, Olivier; Liu, Xiaobo; Vaunat, Jean (Thomas Telford, 2019-06)
      Article
      Accés obert
      This paper presents an experimental study on the swelling response of compacted Maryland clay specimens subjected to hydration under a range of boundary conditions. The research is multi-scale with swelling tests complemented ...
