As the community strives towards autonomous multi-robot systems, there is a need for these systems to autonomously form coalitions to complete assigned missions. Numerous coalition formation algorithms have been proposed in the software agent literature. Algorithms exist that form agent coalitions in both super additive and non-super additive environments. The algorithmic techniques vary from n...

Seawater inundation mapping plays a crucial role in climate change adaptation and flooding risk reduction for coastal low-lying areas. This study presents new elevation model called the digital impermeable surface (DISM) based on topographical data acquired by unmanned aerial vehicle (UAVs) improving seawater mapping. The proposed DISM model, along with bathtub was used to assess vulnerability ...

Three studies examined the relationship between social dominance orientation (SDO), the experience of moral elevation, and Whites' donations to charitable organizations. Study 1 used video clips depicting acts of moral excellence to elicit a state of moral elevation (a distinctive feeling of warmth and expansion, which is accompanied by admiration, affection, and even love for people whose exem...

This study examined the effects of three swallow maneuvers: (1) the supraglottic swallow (voluntary closure of the vocal folds prior to the swallow); (2) the super-supraglottic swallow (airway closure at the level of the arytenoid to base of epiglottis); and (3) the Mendelsohn maneuver (voluntary prolongation of laryngeal elevation and cricopharyngeal opening during swallow) on swallow function...

A novel method for enhancement of the spatial resolution of 3-diminsional Flash Lidar images is being proposed for generation of elevation maps of terrain from a moving platform. NASA recognizes the Flash LIDAR technology as an important tool for enabling safe and precision landing in future unmanned and crewed lunar and planetary missions. The ability of the Flash LIDAR to generate 3-dimension...

In this paper we present a computationally inexpensive way to perform Occlusion Culling in terrain scenes, modelled by elevation maps. The proposed method is based on virtual Occluders [Law99] (i.e. relatively simple structures, that are used to perform the actual visibility test). Unlike most of the related work, we did not seek for an accurate solution, but for a good conservative and inexpen...

Generation of elevation maps of the seafloor is an important component of any autonomous system designed to navigate underwater. Because of its long range, sonar is the sensing medium of choice for underwater navigation. However, sonar systems designed to directly generate 3D images are generally complex or have low resolution. For these reasons, techniques that generate 3D elevation maps from ...
