the effect of boundary conditions on the solution of the inverse problem of identifying the geometry and location of a cavity inside an elastic solid body using displacement measurements obtained from a tension test is investigated. the boundary elements method (bem) coupled with the genetic algorithm (ga) and the conjugate gradient method (cgm) are implemented in this identification problem. a...

finite and boundary element methods have been used by many authors to solve mathematicalphysics problems. however, the coupling of these two methods happens to be more efficient as it combinestheir merits. in this paper, the mathematical analysis of the coupling of finite and boundary element methodsfor the helmholtz equation is presented.

A late Cenomanian-early Turonian interval (Hamam-ghaleh section) adjusted with the transition of Aitamir and Abderaz formations has been investigated in the east of Koppeh-Dagh Basin to examine environmental perturbations related to the oceanic anoxic event 2. The dark shale of the upper Aitamir Formation indicate higher organic matter concentrations especially in the two intervals at the end o...

The sedimentary strata were sampled in the lesser Himalayas to probe paleoenvironmental changes across Cretaceous-Paleogene (K-Pg) boundary eastern Tethys. study provides an integrated lithologic and bio-sequence stratigraphic analysis, leading paleoecology interpretations. planktic foraminiferal limestone of late Cretaceous is overlain by lateritic sandstones sandy limestones, latter being Pal...
