Security is a concern of major importance to governments and companies throughout the world. With limited resources, complete coverage of potential points of attack is not possible. Deterministic allocation of available law enforcement agents introduces predictable vulnerabilities that can be exploited by adversaries. Strategic randomization is a game(More)
Law enforcement agencies frequently must allocate limited resources to protect targets embedded in a network, such as important buildings in a city road network. Since intelligent attackers may observe and exploit patterns in the allocation, it is crucial that the allocations be randomized. We cast this problem as an attacker-defender Stackelberg game: the(More)
In creating an evacuation simulation for training and planning, realistic agents that reproduce known phenomenon are required. Evacuation simulation in the airport domain requires additional features beyond most simulations, including the unique behaviors of firsttime visitors who have incomplete knowledge of the area and families that do not necessarily(More)
The increasing threat of terrorism makes security at major locations of economic or political importance a major concern. Limited security resources prevent complete security coverage, allowing adversaries to observe and exploit patterns in patrolling or monitoring, and enabling them to plan attacks that avoid existing patrols. The use of randomized(More)
In social psychology, emotional contagion describes the widely observed phenomenon of one person’s emotions being influenced by surrounding people’s emotions. While the overall effect is agreed upon, the underlying mechanism of the spread of emotions has seen little quantification and application to computational agents despite extensive evidence of its(More)
In social psychology, emotional contagion describes the widely observed phenomenon of one person’s emotions mimicking surrounding people’s emotions [10]. In this paper, we perform a battery of experiments to explore the existence of agent-human emotional contagion. The first study is a betweensubjects design, wherein subjects were shown an image of a(More)
Security at major locations of economic or political importance is a key concern around the world, particularly given the increasing threat of terrorism. Limited security resources prevent full security coverage at all times, which allows adversaries to observe and exploit patterns in patrolling or monitoring, e.g. they can plan an attack that avoids(More)
SRAM yield is often characterized through distributions of static read or write margins [1] [2]. These measurements are analog and therefore can be slow and provide a limited dataset. Distributions of per-cell minimum operating voltages can be characterized rapidly, however, and are often taken as a proxy to static noise margins. Both methods have a common(More)
