AEROSPACE ENGINEERING engineering.tamu.edu/aerospace Abstract Ductile fracture in metals is an area of active research. While the mechanism of failure (void nucleation, growth and coalescence) in ductile materials is well-understood, the existing models still have several limitations in an accurate prediction of this phenomenon. These models need to be enriched with a more precise understanding...

We studied electromigration (EM) lifetimes and void growth at low cumulative failure probability. We carried out EM test in damascene Cu lines using sudden-death type test structures. Its cumulative failure probability ranges from 0.005 to 90%. To investigate the void growth behaviour, Cu microstructures was investigated. EM lifetime shows correlation with the void nucleation site and the void ...

The current pilot study tested the effectiveness of an e-learning environment built to enable students to compose music collaboratively. The participants interacted online by using synchronous and asynchronous resources to develop a project in which they composed a new music piece in collaboration. After the learning sessions, individual semi-structured interviews with the participants were con...

One way of measuring of the success of a technology is the degree to which it has found acceptance in "real world" companies. These companies will only adopt and continue to use new technology if it lets them solve "real world" problems more effectively than alternative methods and techniques. Critical to this success is the way in which the technology is developed and applied to solve business...

This paper offers a critical review of the literature which explores the building and development of trust in workplace learning, particularly in a virtual context and its implications for Technology Enhanced Learning (TEL) in business. Trust is increasingly recognised as important in both business and education and is the focus of increasing attention in relation to the virtual environment. TE...

Augmented Reality consists of merging live images with virtual layers of information. The rapid growth in the popularity of smartphones and tablets over recent years has provided a large base of potential users of Augmented Reality technology, and virtual layers of information can now be attached to a wide variety of physical objects. In this article, we explore the potential of Augmented Reali...

The current study examined how assessments of copresence in an immersive virtual environment are influenced by variations in how much an embodied agent resembles a human being in appearance and behavior. We measured the extent to which virtual representations were both perceived and treated as if they were human via self-report, behavioral, and cognitive dependent measures. Distinctive patterns...
