friction welding is widely used in various industries. in friction welding, heat is generated by conversion of mechanical energy into thermal energy at the interface the work pieces during pin rotation under pressure. a three-dimensional thermo mechanical simulation of friction stir welding (fsw) processes is carried out for aluminium alloys of 6061and 7050 where the simulation results are comp...

all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...

Abstract This work presents a meshfree particle scheme designed for arbitrary deformations that possess the accuracy and properties of Finite-Element-Method. The is maintained even with distributions. Mesh-based methods mostly fail if requirements on location evaluation points are not satisfied. Hence, this new only range loadings can be increased but also pre-processing step facilitated compar...

Malonamides are known and extensively studied for their lanthanide and actinide extracting properties. Those studies have also highlighted aggregated phenomena and a splitting of the organic phase, in some particular experimental conditions. To explain this behaviour of extractants, (1)H NMR was used to study micellar phenomena by the determination of the self-diffusion coefficients of two malo...

for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...

There are various methods for obtaining the preference vector of pair-wise comparison matrix factors. These methods can be employed when the elements of pair-wise comparison matrix are crisp while they are inefficient for fuzzy elements of pair-wise comparison matrix. In this paper, a method is proposed by which the preference vector of pair-wise comparison matrix elements can be obtained even ...
