Augmented reality technology in U.S. army training (WIP)
Jonathan Stevens,L. Eifert +1 more
- 06 Jul 2014
TL;DR: The definition, history, potential benefits and current employment of augmented reality technology in training, including the Collective Augmented Reality Training for Dismounted Soldiers (CART-DS), is examined.

Transverse mode confinement in lithographic VCSELs
TL;DR: In this article, the index confinement of vertical-cavity surface-emitting laser (VCSEL) was studied experimentally and through modelling for VCSELs.

TL;DR: A heuristic evaluation was conducted to identify strengths and weaknesses of LG-RAID's User Interface (UI) design, with a focus on the importance of being mindful of the cognitive capabilities of the user when designing UIs, understanding and executing simulation design needs based on these capabilities, and the benefits of integrating those design changes during development.
Single-mode behavior of lithographic VCSELs for densely packed arrays
J. Beadsworth,N. Cox,Ja. Leshin,Je. Leshin,M. Li,X. Yang,L. Eifert,F. Tucker,Dennis G. Deppe +8 more

TL;DR: In this paper, a zero index aperture was designed to remove the internal ring modes that oxide VCSELs have, resulting in a lasing pattern with low optical loss, and the aperture was placed near the cavity spacer to improve its effect on confinement and electrical injection.
