Autonomous Convoy Study of Unmanned Ground Vehicles using Visual Snakes
Many applications for unmanned vehicles involve autonomous interaction between two or more craft, and therefore, relative navigation is a key issue to explore. Several high fidelity hardware simulations exist to produce accurate dynamics. However, these simulations are restricted by size, weight, …

Probability model for a convoy threatened by a submarine launched missile
… another dimension to the problem of defending convoys and task groups during ocean transit. The specific situation wherein the submarine must surface to fire a relatively short range missile against a convoy of ships is considered. The model developed considers several different problem …

A proposed methodology for the control of a semi-robotic convoy
… vehicle. The development of this semi-robotic convoy control law begins with a model of an individual vehicle. Two methods are then explored of coupling these into a model of the column. A relationship between these two methods is derived. The model is then expanded to n vehicles. Utilizing a …

Modeling anti-air warfare with discrete event simulation and analyzing naval convoy operations
… explores the most critical success factors of convoy operations. In this study, a discrete event simulation (DES) was built by modeling ships, and their sensors and weapons, to simulate convoy operations under air threat. Where classified data was unavailable, assumptions were made and …

Ethnographic Inquiry of Social Support throughout Women's Labor and Childbirth Experiences
… on the behaviors of the labor and childbirth convoy. Utilizing ethnographic methodology, five women and their support convoys were observed throughout the women's labor and childbirth experience. Word processing and the ETHNOGRAPH software were used for data management, and constant …

The Final Ambush : An Adapted Battlefield Analysis of the U-576 Attack Upon Allied Convoy KS-520 off Cape Hatteras During the Second World War
… Banks into a battlefield. Using a particular convoy battle, the U-boat attack on Allied convoy KS-520 (15 July 1942) as a case study, this thesis seeks to adapt terrestrial battlefield survey techniques to analyze a naval engagement. Drawing from the dominant theoretical and methodological …

Optimization-based allocation of force protection resources in an asymmetric environment
… Combat service support soldiers conducting daily convoy operations on the Iraqi road network account for a large number of these casualties. One reason for this is the threat's affinity to targeting soft, vulnerable, high-payoff targets through the use of roadside bombs, otherwise known as …

The Impact Of Autobiographical And Vicarious Events On Narrative Identity
… and hearsay event for inner and middle circle convoy members) associated with a moral value and completed a social convoy model. Results indicated that autobiographical events were rated significantly higher on event phenomenology and event centrality in comparison to vicarious events overall. …

Constant Time Delay Leader Following for Mobile Robots by using Model Predictive Control Tuned on Estimation Uncertainties
… robots that can be used in a military vehicle convoy. It allows a follower vehicle to follow the same trajectory travelled by a leader with a speci ed time delay by estimating a sequence of waypoints travelled by the leader. This work focuses on the design of the two major components of the …

Optimization-based routing and scheduling of IED-detection assets in contemporary military operations
… to cause catastrophic effects on a passing convoy. Route clearance teams were developed to combat the emerging threat of IEDs. Capable of detecting IEDs with minimal risk to troops, route clearance teams move along the road network in search of these destructive devices. This thesis explores …

Children's social networks and their implications for mental health and well-being
The convoy model of social relations examines social networks as complex and evolving support structures. The exploration of children's social convoys is in its early stages, with limited research investigating how social network characteristics are associated with children's mental health and …
