Augmented Reality is a promising technology for the product lifecycle development, but it is still not established in industrial facilities. The most relevant issues to be addressed relate to the ergonomics: avoid the discomfort of Head-Worn Displays, allow the operators to have free hands and improve data visualization. In this work we study the possibility to use projection-based Augmented Re...

Augmented reality (AR) is one of the emerging technologies gradually venturing into education field. Although AR strongly linked to subjects related Science, Mathematics, and Technology in schools tertiary education, there no mention non-technical subjects, such as language. Thus, this study aims discover application trends language learning skills prevalent usage. In systematic literature revi...

This article presents a study on Augmented Reality (AR) development as a new performance approach for collaborative space of urban design work. Here, the participantse.g. architects, structure engineers, equipment vendors, etccan view an urban design process through AR scenes by Head-Mounted Display (HMD) glasses. Nowadays, the AR technology has been supported as a great graphical computing tec...

The post-earthquake retrofitting and repair process of a building is key factor in improving its seismic capability. A thorough understanding methods processes will aid repairing buildings resilience. This study aims to develop visualization framework for the which builds models based on information modeling (BIM) realizes using augmented reality (AR). First, multi-level representation coding c...

Abstract Augmented reality (AR) is playing an increasingly important role in a variety of everyday application scenarios. Users are not completely disconnected from the current sensory influences reality. They merely confronted with additional virtual objects that projected into This allows users to obtain spatial information, which makes this technology interesting for cartographic application...

The objective of this paper is to examine the performance of specific technical rules in the Athens Stock Exchange (ASE). In particular, we further investigate and provide modifications for Brock, Lakonishok, and LeBaron (1992) methodology, finding various forms of technical analysis that contain significant forecast power for ASE returns. Furthermore, we test one of the most popular trading ru...

Anatomical resection (AR) has been reported to achieve better long-term outcomes than non-anatomical for the treatment of hepatocellular carcinoma (HCC). The surgical feasibility and oncological significance laparoscopic AR (LAR), especially “subsegment resection”, “cone unit repeat LAR HCC, remain unproven. We present a 67-year-old patient with alcoholic liver cirrhosis HCC who underwent full ...
