Literature on explanation has shown that explanations have a positive impact on users’ acceptance of and trust in the advice provided, and that justification-type explanations give rise to more positive user perceptions of a system. This paper suggests a framework for organizing justifications, which is based on Toulmin’s model of argument and Habermas’ discourse theory. It justifies and illust...

Bubble formation is a well identified phenomenon within short (ns) and ultrashort (fs) laser pulses-aqueous media interactions. Bubble formation might be produced by three different mechanisms: (1) optical breakdown, (2) rarefraction wave and (3) overheating of the material. Experiments where transparent and scattering tissue models that mimic biological tissue were irradiated with a Q-switched...

Psychological research findings suggest that humans rely on the combined visual channels of face and body more than any other channel when they make judgments about human communicative behavior. However, most of the existing systems attempting to analyze the human nonverbal behavior are mono-modal and focus only on the face. Research that aims to integrate gestures as an expression mean has onl...

The current study examines the impact of different task types on learning prepositions in form and meaning- focused interaction enhancement- based classes. The participants were 57 second Year University students enrolled in three intact lab classes at Tabriz Islamic Azad University.  The first group was provided with form-focused interaction enhancement, the second with the meaning-focused int...

      Social interaction among different ethnic groups has been a major focus of study in the world in recent decades. The population of Iran is composed of variety of ethnic groups (such as linguistic, religious and cultural) and for this study the people of different backgrounds are considered. This article will discuss the types of social interaction among different ethnic groups and the rol...

In recent years, the production of oil and gas has been developed in deep water depths which exceed 500m. Deep water developments are being followed strongly in different parts of the world (Caspian Sea, Gulf of Mexico, etc.). The movement of floater causes severe stress at the touchdown point (TDP) in steel catenary risers (SCR). The main objective of this study was to simulate the exact behav...

the character of the intermolecular interactions in cl2-hx (x =f, cl and br) complexes has been investigated by means of the second-order möller–plesset perturbation theory (mp2) and the density functional theory (dft) calculations. the results show that there are two types of lowest interaction potential equilibrium structures in the interactions between cl2 and hx: x∙∙∙cl type geometry and hy...
