Topographie montagnarde, forts épisodes pluvieux et structure de sol prédominée par des matériaux tendres essentiellement des marnes, sont toutes des contraintes environnementales qui ont fait des talus de l’autoroute Fès-Taza une zone très exposée à l’érosion hydrique. Ces talus ont présenté de sérieux problèmes d’érosion depuis la première année ...

In this paper, author’s aim is to investigate the tendencies of EU27 countries based on road transport safety and road transport-related CO2 emission. On EU level huge efforts have been made in order to reduce the number of fatal road accidents and to reduce the CO2 emission as well. There is a strong revealed driving force behind the connection of...

This paper presents a new macroscopic multi-class dynamic network loading model called Dynamic Queuing Transmission Model (DQTM). The model utilizes ‘good’ properties of the Dynamic Queuing Model (DQM) and the Link Transmission Model (LTM) by offering a DQM consistent with the kinematic wave theory and allowing for the representation of multiple ve...
We develop a singular crack element for the general anisotropic solids in two dimensions for the mixed mode boundary element analysis of multiple straight cracks. Given a normalized crack along an interval (−1, +1) on the X-axis, we represent the crack opening displacement (COD) by the continuous distribution of dislocation dipoles, which is ...
This paper presents some recent advances in the boundary element method (BEM) for the analysis of carbon nanotube (CNT)-based composites. Carbon nanotubes, formed conceptually by rolling thin graphite sheets, have been found to be extremely stiff, strong and resilient, and therefore may be ideal for reinforcing composite materials. However, the thi...

The urgency of the issues discussed in this paper stems from the fact that cross-border collaboration is an essential part of commercial transportation today. With the extension of multimodal transportation concept, the efficiency and performance of not only national but also of regional transport systems depend on a synergy which occurs as a resul...

This study examines non-white candidate textual and visual framing (Reese, 2003) in the context of a local election, as informed by print national press and a telenovela, to assess the current state of media opening in Brazil. It analyzes a sample of 313 newspaper and newsmagazine reports and 292 photos concurrent with when municipal campaigns were...
Aims: The study was done to analyze current trend of unsafe abortion.Methods: It was a prospective study where all the abortion related admissions from January 2009 to December 2011, in Obstetrics and Gynaecology unit at B.P. Koirala Institute of Health Sciences were analyzed. Sixty-six women with diagnosis of unsafe abortion were enrolled in the s...
Based on the Rizzo’s direct boundary integral equation formulation for elasticity problems, elastic bodies with randomly distributed circular inclusions are simulated using the boundary element method. The given numerical examples show that the boundary element method is more accurate and more efficient than the finite element method for suc...
This paper presents the implementation of the boundary element method to shape sensitivity analysis of elastic structures with stress concentrators. An elastic body which contains a number of voids (internal boundaries), playing the role of stress concentrators, is considered. We are interested in calculating the first order sensitivity of shapeââ...
