We study plan synthesis for a variant of Knowledge and Action Bases (KABs), a rich, dynamic framework, where states are description logic (DL) knowledge bases (KBs) whose extensional part is manipulated by actions that possibly introduce new objects from an infinite domain. We show that plan existence over KABs is undecidable even under severe restrictions. We then focus on state-bounded KABs, ...

Long-chain perfluorinated chemicals (PFCs) are found world-wide in the environment, wildlife, and humans. They are bioaccumulative in wildlife and humans, and are persistent in the environment. To date, significant adverse effects have not been found in the general human population; however, significant adverse effects have been identified in laboratory animals and wildlife. Given the long half...

Twenty years ago, a book was published entitled World mental health: problems and priorities in low-income countries (1). A few years later in 2001, the World Health Organization (WHO) devoted its World Health Report to Mental health: new understanding, new hope (2), and the Institute of Medicine in the United States of America brought out Neurological, psychiatric, and developmental disorders:...

There is increasing awareness in the planning community that the burden of specifying complete domain models is too high, which impedes the applicability of planning technology in many real-world domains. Although there have been many learning approaches that help automatically creating domain models, they all assume plan traces (training data) are correct. In this paper, we aim to remove this ...

A PACKAGE of measures designed to overcome growing recruitment and retention problems in Scotland has won only a lukewarm reception from nursing leaders.

In complex environments, a planning system may be faced with incomplete information about both the planning operators and the state of the world. Previous research has investigated policies for selecting the best plan to execute, given incomplete operator descriptions. This paper extends that work to support interleaved planning and execution by taking into account past and current sensor readi...

In this article, a study of employee’s opinion to the factors that affect to the flood preventive and the corrective action plan in an electronic industry at the Sharp Manufacturing (Thailand) Co., Ltd. has been investigated. The surveys data of 175 workers and supervisors have, however, been selected for data analysis. The results is shown that the employees emphasize about the needs in a subs...

management of the forest resources and related activities has significant effects on the environment. applying the environmental impact assessment (eia) provides a basis for improving forest management plans. however, in the developing countries such as iran, there have been so far no serious endeavors and research to undertake the eia of the various practices affecting the forest resources, de...
