This paper reports on lessons learned in sensor placement and search strategies for nuclear forensics from a 2013 field exercise. Nuclear forensics, where a radiological source is located, has been the subject of theoretical research but only one reported instance with an actual robot (Fukushima). The field exercise specifically focused on source(More)
As robotic systems become more sophisticated, they are increasingly called upon to accompany humans in high-stress environments. This research was conducted to support the integration of robotic systems into tactical teams operating in challenging and stressful environments. Robotic systems used to assist tactical teams will need to support some form of(More)
Therabot™ is an assistive-robotic therapy system designed to provide support during counseling sessions and home therapy practice to patients diagnosed with conditions associated with trauma. It has the form factor of a floppy-eared dog with coloring similar to that of a beagle, and comfortably fits in a person's lap.
Therabot is an assistive-robotic therapy system designed to provide support during counseling sessions and home therapy practice to patients diagnosed with conditions associated with trauma. Studies were conducted to determine desired features of potential end-users of the system, such as clinicians, with feedback from past survivors of trauma to guide the(More)
The structures of the colicin Ib plasmid (ColIb), the delta transfer factor and a plasmid determining kanamycin resistance and colicin Ib production called KColIb, were compared. Radiolabelled mini-ColIb plasmids and isolated DNA fragments of ColIb were used as probes for nitrocellulose blots of digests of the other two large plasmids. The structure of(More)
The study investigated whether emotionally provoking disagreements between 36 marriage partners influenced their ability to identify each other's feelings from tone of voice cues. The results suggested that among the males the ability of stable introverts to identify increased after disagreements, while that of neurotic introverts decreased (p smaller than(More)
