In present study, the effect of reservoir length on seismic performance of concrete gravity dam has been investigated. Monte Carlo probabilistic analysis has been used to achieve a sensitivity of the responses to variation of truncated reservoir length in finite element model. The ANSYS software based on finite element method is applied for modeling and analysis. The Pine Flat dam in California...

Assessment of the correlation between rock brittleness and rock fracture toughness has been the subject of extensive research works in the recent years. Unfortunately, the brittleness measurement methods have not yet been standardized, and rock fracture toughness cannot be estimated satisfactorily by the proposed indices. In the present study, statistical analyses are performed on some data col...

objectives this study aimed to assess the effect of object position in the field of view (fov) of cbct on detection of vrfs in teeth with intra-canal posts. materials and methods the crowns of 60 extracted premolar teeth were cut at the level of cementoenamel junction (cej). root canals were filled with gutta-percha and filling of the coronal 2/3 of the root canals was subsequently removed to f...
