Versatility, Portability, GPS compass and Location based information are added advantage to Mobile augmented reality. This paper talks about the Mobile Augmented Reality (AR), its technological overview and architecture, Interactive storytelling and reasons how it can help to change the world when it is combined along with augmented reality are also stated. Thus, advantages and applications of MAR are highlighted to support the powerful technology with evidence.

Research paper thumbnail of Characteristics Studies of Stainless Steel (AISI Type 304l) Welded by Er310l Filler Using Tig Welding

Welding requires properties like corrosion resistance, wear resistance and hardness. The corrosion and wear rate depends on the atmospheric conditions and engineering applications. The welded AISI type 304L stainless steel is subjected to post weld heat treatment during welding process. This welding process suffers by ferrite and carbon contents. The filler ER310L is selected and welded with stainless steel (AISI type 304L) by Gas tungsten Arc welding (TIG welding) method. Satisfactory results are obtained from tensile test, hardness test, impact strength and microstructures, which makes it eligible for engineering applications. This research work elevates the corrosion resistance and mechanical properties of stainless steel (AISI type 304L) economically for the engineering applications.

Past studies have failed in this enterprise because they did not consider three shortcomings that limit the predictive Ž. Ž. power of environmental attitude concepts: 1 the lack of a unified concept of attitude, 2 the lack of Ž. measurement correspondence between attitude and behaviour on a general level, and 3 the lack of consideration of behaviour constraints beyond people's control. Based on Ajzen's theory of planned behaviour, the present study uses a unified concept of attitude and a probabilistic measurement approach to overcome these shortcomings. Questionnaire data from members of two ideologically different Swiss transportation associations are used. This study confirmed three measures as orthogonal dimensions by means of factor Ž. Ž. Ž. analysis: 1 environmental knowledge, 2 environmental values, and 3 ecological behaviour intention. One other measure, general ecological behaviour, is established as a Rasch-scale that assesses behaviour by considering the tendency to behave ecologically and the difficulties in carrying out the behaviours, which depend on influences beyond people's actual behaviour control. A structural equation model was used to confirm the proposed model: environmental knowledge and environmental values explained 40 per cent of the variance of ecological behaviour intension which, in turn, predicted 75 per cent of the variance of general ecological behaviour.
