The influence of pre-retirement leisure activity patterns on retirement planning and attitudes toward retirement was investigated. Sixty male retirees answered a questionnaire designed to collect data regarding sociodemographic variables, the degree of preretirement planning, the type and extent of leisure participation before and after retirement, and attitudes about retirement. The results sh...

dry eye is the major contributor to computer vision syndrome. the reductions in the blink rate and amplitude have been considered as the possible mechanisms leading to this condition. the purpose of this study is to evaluate the changes in the lower tear meniscus heights and areas in the computer reading task, in dry eye subjects, with and without soft contact lenses. in this quasi-experimental...

RIFO, as has been proposed by Nebel et al. (Nebel, Dimopoulos, and Koehler 1997), is a method that can automatically detect irrelevant information in planning tasks. The idea is to remove such irrelevant information as a pre-process to planning. While RIFO has been shown to be useful in a number of domains, its main disadvantage is that it is not completeness preserving. Furthermore, the pre-pr...

We present a new approach to the multi-robot path planning problem, where a number of robots are to change their positions through feasible motions in the same static environment. Rather than the usual decoupled planning, we use a coordinated approach. As a result we can show that the method is probabilistically complete, that is, any solvable problem will be solved within a nite amount of time...

The algorithmic generation of textual descriptions of image sequences requires conceptual knowledge. In our case, a stationary camera recorded image sequences of road traffic scenes. The necessary conceptual knowledge has been provided in the form of a so-called Situation Graph Tree (SGT). Other endeavors such as the generation of a synthetic image sequence from a textual description or the tra...

One resource playing a critical role in electronically supported decision-making groups is the facilitator. Facilitation is a complex task, encompassing social abilities, pre-meeting planning of decision-making processes and supervising the technology usage during meetings. We found two problems with previous support to electronic facilitation: (1) limited support to planning activities; and (2...

We present a compilation-based approach to reducing the representational distance between application domain experts and AI planning technology. The approach combines a representation designed to match the structure of human expertise in the construction industry with an established planning technique. The design of this representation is derived from a study carried out with experts in the ind...

The Action Notation Modeling Language (ANML) provides a high-level, convenient, and succinct alternative to existing planning languages such as PDDL, the IxTeT language, and languages developed at NASA, such as the EUROPA modeling language (NDDL), and the ASPEN modeling language (AML). ANML is based on strong notions of action and state (like PDDL, IxTeT, and AML), uses a variable/value model (...
