This paper presents an efficient reduction method for predicting the nonlinear transient and steady state squeal events in mechanical systems subjected to friction-induced vibration noise. proposed technique is based on Double Modal Synthesis (DMS) that involves use of a classical Craig & Bampton modal each substructure considering interface surfaces associated condensation at frictional comple...

INTRODUCTION Interstitial pulmonary fibrosis (IPF) is a frequent manifestation in patients with connective tissue disorders (CTD). Recently the ultrasound (US) criterion validity for its assessment has been proposed; however, the US scoring systems adopted include the study of several lung intercostal spaces (LIS), which could be time-consuming in daily clinical practice. The aim of this study ...

this paper presents an auto redundant technique for analysis of grid with curved members.this technique is based on the force method, but in the technique choice of the redundant iscompletely eliminated. the analysis technique is found very effective, accurate andprogrammable. a comprehensive c++ program has been developed to compute internalforces at the end of each member of the grid for diff...

investigation of desertification trend requires an understanding of phenomena that create changes singly or action and reaction together in an area that these changes were led to the desertification and land degradation. in the investigation of pedological criterion affecting on land degradation in alluvial fans, first, the map of units was created by overlaying and crossing maps of slope class...

pedological criterion affecting desertification in alluvial fans was investigated, for which the map of units was prepared by crossing maps of land use, geology, slope classes and grid layer created by the extension of et geo-wizards in arcgis 10.3. three indices of salinity, erodibility, and permeability of soil were considered and classified. weights of criteria and consistency ratio were cal...
