Why Get A Warrant When You Can Fly Over The Wall? The Constitutionality Of Aerial Surveillance Without A Warrant, Royce A. Deller

New Mexico Law Review

Individuals in and around their home have a reasonable expectation of privacy from warrantless, ground-level surveillance because the curtilage of the home, like the home itself, is protected from searches and seizures. This is settled Fourth Amendment law. The curtilage of a home is “the area to which extends the intimate activity associated with the ‘sanctity of a man’s home and the privacies of life.’” Less clear, however, is whether there is a reasonable expectation of privacy from aerial surveillance. One would be forgiven for assuming one enjoys an expectation of privacy from surveillance in the curtilage of one’s own …

Search In T Cell And Robot Swarms: Balancing Extent And Intensity, George M. Fricke

Computer Science ETDs

This work investigates effective search and resource collection algorithms for swarms. Deterministic spiral algorithms and L ́evy search processes have been shown to be optimal for single searchers. We extend these strategies to swarms of robots and populations of T cells and measure performance under a variety of conditions.

Search extent and intensity lie on a continuum: more intensive patterns search thoroughly in the local area, while extensive patterns cover more area but may miss targets nearby. We show that the most efficient trade-off between search intensity and extent for swarms depends strongly on the distribution of targets, swarm size …

Hopscotch: Robust Multi-Agent Search, Edward C. Miles

Computer Science ETDs

The task of searching a space is critical to a wide range of diverse applications such as land mine clearing and planetary exploration. Because applications frequently require searching remote or hazardous locations, and because the task is easily divisible, it is natural to consider the use of multi-robot teams to accomplish the search task. An important topic of research in this area is the division of the task among robot agents. Interrelated with subtask assignment is failure handling, in the sense that, when an agent fails, its part of the task must then be performed by other agents. This thesis …

Why I Can't Love The Homemade Semantic Web, Jason Bengtson

Publications

Almost all information professionals agree that the web needs to move to a semantic structure. While work is proceeding in this area, movements to get individual web authors to use semantic markup tools have also been on the rise. This author argues that such efforts are ill conceived and he proposes an automated alternative.

Task-Driven Multi-Formation Control For Coordinated Uav/Ugv Isr Missions, Herbert G. Tanner

Mechanical Engineering Faculty Publications

The report describes the development of a theoretical framework for coordination and control of combined teams of UAVs and UGVs for coordinated ISR missions. We consider the mission as a composition of an ordered sequence of subtasks, each to be performed by a different team. We design continuous cooperative controllers that enable each team to perform a given subtask and we develop a discrete strategy for interleaving the action of teams on different subtasks. The overall multi-agent coordination architecture is captured by a hybrid automaton, stability is studied using Lyapunov tools, and performance is evaluated through numerical simulations.
