pulsed current plasma arc welding (pcpaw) is one of the most widely used welding processes in sheet metal manufacturing industry. in any fusion arc welding process, the weld bead geometry plays an important role in determining the mechanical properties of the weld and hence quality of the weld.  moreover, the geometry of weld bead involves several simultaneously multiple quality characteristics...

nowadays, in order to reach minimum production cost in machining operations, various optimization methods have been proposed. since turning operation has different parameters affecting the workpiece quality, it was selected as a complicated manufacturing method in this paper. to reach sufficient quality, all influencing parameters such as cutting speed, federate, depth of cut and tool rake angl...

The ability to reason about information is an essential human capability. It is less understood from the perspective of neurocognitive processes which can serve to constrain cognitive theories by implications from neuroscientific data. Despite some progress in the last decades, some disagreement about the experimental results and the cognitive processes of reasoning with abstract relations vers...

Language is a powerful instrument for extracting relational information from stimuli. In a label extension task common labels invite comparison processes that help children focus on the more subtle relational similarity and away from the readily available perceptual similarity of the stimuli. The current experiment aims to explore whether non-linguistic representations of category membership ar...

Electronic ties are loosening the constraints of organizational structure and physical proximity to allow connectivity between individuals who would otherwise find it difficult to identify and sustain contact with others who share the similar interests. This paper explores the knowledge exchange processes in extra-organizational networks of practice by studying three technical newsgroups. We ar...

Mental representations of personal relationships or relational schemata strongly influence the interactions with the relationship partners, and in turn, relationship success. Since the beginnings of relationship research scholars have postulated that important features of relational schemas may not be accessible to introspection. The present chapter reviews the literature on such implicit cogni...

Relational algebra in the sense of Schr oder and Tarski has been thoroughly studied by mathematicians from the universal algebraic viewpoint and some research has shown many applications of the relational calculus in the elds of graph theory and computer science This paper addresses the eld of process algebraic languages which are used for the speci cation and veri cation of communicating syste...

Understanding positive emotions' shared and differentiating features can yield valuable insight into the structure of positive emotion space and identify emotion states, or aspects of emotion states, that are most relevant for particular psychological processes and outcomes. We report two studies that examined core relational themes (Study 1) and expressive displays (Study 2) for eight positive...

We report two studies which examine the age stereotypes in interactions model of intergenerational communication. We investigate whether stereotyping processes mediate the effects of various predictors on communication outcomes. Support emerges for the mediating role of stereotyping. The studies also examine relational factors fi nding support for the argument that relational factors deserve mo...

Relational database management systems are used to store and manage large sets of data, subsets of which can be of interest in the context of Model Driven Engineering processes. To enable seamless integration of information stored in relational databases in an MDE process, the technical and conceptual gap between the two technical spaces needs to be bridged. In this paper we investigate the cha...
