Effects of annealing treatment after equal channel angular pressing (ECAP) on the interface properties and shear bond strength of Al/Cu bimetallic rods were investigated. For the as-deformed samples, the one with two passes of ECAP indicated higher shear bond strength. Formation of a layer of intermetallic compounds after annealing treatment is confirmed. In general, by increasing annealing tem...

Conventional computer interfaces, such as a keyboard or a mouse, are limited in the information they provide. For instance, they cannot tell computers about actions we intend to perform or imagine performing (e.g., moving a limb) or mental states we are in (e.g., emotional or attentional state). In contrast, a braincomputer interface (BCI) can provide this information. BCIs interpret our brain ...

unlike the languages we know, some of the arabic sentences form without any verbs. arab grammarians call these sentences, which contain a subject and a predicate without any linking verbs, nominal sentences. examining theses sentences indicates that their predicate is composed of one of the following words or structures: 1. noun, 2. prepositional phrase, 3. an adverb of time or place, 4. a nomi...

in this research, effect of bicomponent mixed surfactant was studied on drop interface coalescence phenomenon in ambient temperature. first basic chemical system was water and toluene and 0.01 gr of sodium dodecyle sulfate (sds) and the second basic system was water and toluene and 0.01 gr of cethyl trimethy amonium bromide (ctab). various weight fractions of second surfactant including 2-hepta...

For the analysis of composite media, three different compatible and mixed finite element formulations are presented which apriori enforce the continuity of stresses as well as displacements at the element interfaces. The formulations are applied for the analysis of hi-material interfaces in two problems often encountered in the field of orthopaedic biomechanics, that is the fixation analysis in...
