A potential-flow based flight simulator for an underwater glider [PDF]

open access: yes, 2013
Underwater gliders are recent innovative types of autonomous underwater vehicles (AUVs) used in ocean exploration and observation. They adjust their buoyancy to dive and to return to the ocean surface.

Functional Differentiation of Type II and Type I Collagen Articular Models in Synovial Fluid Film Formation and Recombinant Equine Lubricin Retention

open access: yesAdvanced Functional Materials, EarlyView.
Collagen II coatings support the formation of synovial fluid nanofilms, while collagen I coatings do not. Both bind recombinant equine lubricin similarly. These findings may help explain articular cartilage surface joint dysfunction, inform biomaterial design for synovial joint repair, and expand on lubricin‐based osteoarthritis therapies.

An Architecture for Cooperative Localization in Underwater Acoustic Networks [PDF]

open access: yesProceedings of the 10th International Conference on Underwater Networks & Systems, 2015
This paper outlines an architecture for underwater acoustic cooperative localization. Our system leverages communication within an acoustic network to both share navigation information and measure the relative range between vehicles. We employ a factor graph framework for vehicle position estimation.
