â â â  in the last years, have been accelerated increased the damages of landslides by natural and anthropogenic factors. one of the main solutions to decrease landslide hazards is avoid from prone areas. for this purpose, it is necessary to prepare the landslide susceptibility map. in this research, after field studies in the ilam dam basin, nine factors including slope gradient, aspect, eleva...

Landslide risks are frequently underestimated by political and economic actors as well as by the local population. The InterRisk Assess research project is working to develop a systematic approach to the analysis and evaluation of economic landslide risks at a local and regional scale. Its major aims are to determine the extent of potential damage and economic losses caused by landslides, to an...

     The landslides impose serious damages to the economy, environment and human throughout the world. Identification of areas susceptible to landslides is necessary to avoid risks. In This research for Landslide hazard zonation in sarkhoon karoon watershed have been used Shannon’s Entropy Index and Information Value Methods. For this purpose, at first, landslide locations were identified using...

The landslides cause several casualties and economic losses all over the world. Studies show that most casualties happen within the first 18-35 minutes after the burial. This demands life-detecting systems to be available immediately on the spot after the disaster. A suggested approach is deploying multiple units of these instruments across the country. Main constraint in developing countries f...

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...

translation studies have become an accepted academic subject and books, journals and doctoral dissertations appear faster than one can read them all (bassnet and lefevere, 1990). but this field also brought with itself so many other issues which needed to be investigated more, in the heart of which, issues like ideology, ethics, culture, bilingualism and multilingualism. it is reported that ove...

landslides are the major natural hazard, causing significant damage to properties, lives and engineering projects in all mountainous areas in the world. in order to estimate the role of the landslides in erosion processes and evaluation of their risks, it is necessary to quantify landslides. this quantifying can be performed by applying the probability distributions that show the landslide size ...

This paper presents a novel coupled formulation for fluid-structure interaction (FSI) problems involving free-surface fluid flows, fracture phenomena, solid mutual contact and large displacements. The numerical combines three different Lagrangian computational methods. Particle Finite Element Method (PFEM) is used to solve the flow, (FEM) with smoothed isotropic damage model employed solution o...

In this study, an approach for damage detection of large-scale structures is developed by employing kinetic and modal strain energies and also Heuristic Particle Swarm Optimization (HPSO) algorithm. Kinetic strain energy is employed to determine the location of structural damages. After determining the suspected damage locations, the severity of damages is obtained based on variations of modal ...
