Traditionally, distributed queries have been optimized centrally and executed synchronously. We outline a framework that relaxes both of these constraints using mutant query plans: XML representations of query plans that can also include verbatim XML data, references to resource locations (URLs), or abstract resource names (URNs). Servers work using local, possibly incomplete knowledge, partial...

In this paper, we present a dynamic logic for a propositional version of the agent programming language 3APL. A 3APL agent has beliefs and a plan. The execution of a plan changes an agent’s beliefs. Plans can be revised during execution by means of plan revision rules. Due to these plan revision capabilities of 3APL agents, plans cannot be analyzed by structural induction as in for example stan...

Despite the significant advances that software and hardware technologies have brought to the emergency management field, some islands remain where innovation has had little impact. Among them, emergency plan management is of particular relevance due to their key role in the direction of teams during responses. Aspects like coordination, collaboration, and others are spread in plain text sentenc...

A fundamental assumption made by classical AI planners is that there is no uncertainty in the world: the planner has full knowledge of the conditions under which the plan will be executed and the outcome of every action is fully predictable. These planners cannot therefore construct contingency plans, i.e., plans in which di erent actions are performed in di erent circumstances. In this paper w...

Background: Radiation Pneumonia (RP) is one of the most extensive side effects in Stereotactic Body Radiotherapy (SBRT) of lung cancer. SBRT are performed by means of Intensity Modulated Radiotherapy (IMRT), Intensity Modulated Arc Therapy (IMAT), CyberKnife (CK) or Helical Tomotherapy (HT) treatment methods. In this study, we performed a plan study to determine the plan parameter such as the M...

In most application domains for distributed arti cial intelligence, several autonomous agents (e.g., companies or personal assistants) each have their own goals. They need to plan for these goals, coordinate their actions, deal with uncertainty, and interleave all this with plan execution [2, 4]. To complicate matters even more, many agents are self-interested and require some privacy concernin...

A rapidly growing public policy concern facing the United States is whether future generations of retired Americans, particularly those in the "baby boom" generation, will have adequate retirement incomes. One reason is that Social Security's projected long-term financial shortfall could result in a reduction in the current-law benefit promises made to future generations of retirees. Another re...
