study of cohesive devices in the textbook of english for the students of apsychology by rastegarpour
this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
Parallel embedded-atom method simulations with delayed electron density approximations
The embedded-atom method (EAM) is a popular tcchni;!ue for the atomic simulation of meals and alloys. The EAM procedure involves two computational phases; the first to e,,aluate electron densities and the second to evatua~e e ~ energies and repulsive forces. Substantial computational ce ~ts are required for each phase, particularly for khe simaJafio¢ of large particle systems. On distributed-me...
متن کاملAtomistic Simulations of the Motion of an Edge Dislocation in Aluminum Using the Embedded Atom Method
The motion of an edge dislocation is analyzed for temperatures ranging from 10 K to 200 K and for stresses up to 5 GPa. The dislocation velocity versus the applied shear stress curve can be divided into four regimes corresponding to successively higher shear stresses. In the first regime, the applied shear stress is below the Peierls stress and the dislocation velocity is nominally zero. In the...

متن کاملStructural stability and lattice defects in copper: Ab initio, tight-binding, and embedded-atom calculations
We evaluate the ability of the embedded-atom method ~EAM! potentials and the tight-binding ~TB! method to predict reliably energies and stability of nonequilibrium structures by taking Cu as a model material. Two EAM potentials are used here. One is constructed in this work by using more fitting parameters than usual and including ab initio energies in the fitting database. The other potential ...
