OBJECTIVE To determine the workload implications for general practice of the Coronary Prevention Group and British Heart Foundation action plan for preventing heart disease. DESIGN Computer simulation of plan, including calculation of Dundee risk scores, with data from OXCHECK trial. SUBJECTS 4759 patients aged 35-64 who had health checks during 1989-91. MAIN OUTCOME MEASURE Effect of usi...

OBJECTIVES High rates of malnutrition have been reported in the older hospitalized patient population. This is recognised to impact on patient outcomes and health costs. This study aimed to assess the impact of nutrition screening and intervention on these parameters. DESIGN Randomised controlled prospective study. SETTING The study was performed in the acute geriatric medicine wards of the...

SharedPlans is an agent teamwork model that provides a formalization of the conditions under which a group of agents has a collaborative plan. This paper describes a general framework for implementing SharedPlans theory that addresses the computational issues of team formation, group plan elaboration and plan execution, involving coordination, communication and monitoring. The framework include...

Plan-related inference has been one of the most-studied problems in Artificial Intelligence. Pollack (1990) has argued that a plan should be seen as a set of mental attitudes towards a structured object. Although the objects of these attitudes have received far more attention to date than the attitudes themselves, little has been said about the exact meaning of one of their key components -the ...

We present the PHATT algorithm for plan recognition. Unlike previous approaches to plan recognition, PHATT is based on a model of plan execution. We show that this clarifies several difficult issues in plan recognition including the execution of multiple interleaved root goals, partially ordered plans, and failing to observe actions. We present the PHATT algorithm’s theoretical basis, and an im...

In this report is presented a work plan towards a PhD thesis on the Simultaneous Localization And Mapping problem. In the first part, an analysis of the problem is presented, followed by a survey of the state of the art. After pointing out some open issues, a research plan is then sketched.

In this paper, we present a general model for plan sentinel agents. We raise some of the important design issues for sentinel systems, and discuss some of the implications for several DARPA Programs with which we have recent experience. We conclude that sentinel agents will provide both human and automated planners with relevant feedback on plan execution

Domain-independent planning is a hard combinatorial problem. Taking into account plan quality makes the task even more di cult. We introduce a new paradigm for e cient high-quality planning that exploits plan rewriting rules and e cient local search techniques to transform an easy-to-generate, but possibly suboptimal, initial plan into a low-cost plan. In addition to addressing the issues of e ...

Recently we introduced interactive dose shaping (IDS) as a new IMRT planning strategy. This planning concept is based on a hierarchical sequence of local dose modification and recovery operations. The purpose of this work is to provide a feasibility study for the IDS planning strategy based on a small set of six prostate patients. The IDS planning paradigm aims to perform interactive local dose...
