We present an architecture that provides a robust, scalable and flexible software framework for planning and scheduling systems through the use of standardized industrial-strength middleware and multi-agent technology. It utilizes knowledgebased components that dynamically perform and verify the system’s configuration. The system is based on a proper formal account of hybrid planning, the integ...

The current study, setting a two-fold goal, attempted to see whether the preemptive focus on form (FonF) under either planned or unplanned conditions could contribute to increasing lexical diversity in written narratives and, second, to find whether there was a trade-off between the lexical diversity and accuracy. To this end, 32 beginner learners were selected following a Quick Oxford Placemen...

The shift of emphasis away from written to oral skills has stimulated an incipient concern in second language research to investigate ways of helping second and foreign language learners achieve higher degrees of oral proficiency. Priority solely taken over accuracy, complexity, or fluency of speech might be justifiable with regard to the context in which learning takes place.  Accuracy and com...

Many real-world application domains that demand planning and scheduling support do not allow for a clear separation of these capabilities. Typically, an adequate mixture of both methodologies is required, since some aspects of the underlying planning problem imply consequences on the scheduling part and vice versa. Several integration efforts have been undertaken to couple planning and scheduli...

As a sustainability property, energy efficiency is of an extreme importance, especially in environments that are heavy energy consumers, such as homes and buildings. Nowadays, homes and buildings are equipped with many devices that could be exploited in order to make them smart and energy-efficient. Our vision is to bring convergence of smart environments, energy efficiency and automated planni...

In this paper we address the problem of generating preferred plans by combining the procedural control knowledge specified by Hierarchical Task Networks (HTNs) with rich user preferences. To this end, we extend the popular Planning Domain Definition Language, PDDL3, to support specification of simple and temporally extended preferences over HTN constructs. To compute preferred HTN plans, we pro...

niques is now the world champion computer program in the game of Contract Bridge. As reported in The New York Times and The Washington Post, this program—a new version of Great Game Products’ BRIDGE BARON program—won the Baron Barclay World Bridge Computer Challenge, an international competition hosted in July 1997 by the American Contract Bridge League. It is well known that the game tree sear...

Despite the recent advances in planning for classical domains, the question of how to use domain knowledge in planning is yet to be completely and clearly answered. Some of the existing planners use domain-independent search heuristics, and some others depend on intensively-engineered domainspecific knowledge to guide the planning process. In this paper, we describe an approach to combine ideas...

aim and background: multiple sclerosis (ms) is a chronic inflammatory disease of the central nervous system in which primary symptoms emerges in adults between the age 20 and 40 years old. previous findings indicate 15-20 percent of multiple sclerosis (ms) patients are diagnosed with executive function impairments. the purpose of this study is to evaluate planning function as one of executive f...
