    This paper presents selected aspects of information processing in frames. The slots of frames are considered as taking on linguistic values represented as fuzzy sets. Matching procedures are developed and algorithms resulting within this context are proposed. The question of modeling cases involving many exemplar frames associated with a single prototype frame is posed. Subsequently the resulting ... View full abstract»

    We present OPUS, a framework that provides design guidelines for the systematic building of independent, and potentially heterogeneous, knowledge base programs for the domains of large physical structures. The term open-system refers to the integration of several of these programs to solve problems beyond their individual capabilities. The OPUS framework organizes data and knowledge about the doma...

    As an alternative to coordinate locations, patterns of points can be represented using interpoint distances. In certain applications, such as dimensioning and multidimensional scaling, interpoint distances have traditionally been used. In other applications, such as radar location, interpoint distance information is readily obtained, This paper utilizes kinematics, rigidity theory, and graph algor... View full abstract»

    As simulator-based training systems become more complex, the amount of effort required to generate, monitor, and maintain training exercises multiplies greatly. This has significantly increased the burden on the instructors, potentially making the training experience less efficient as well as less effective. Research on intelligent tutoring systems (ITS) has largely addressed this issue by replaci... View full abstract»

    This paper describes a system named AA1 (Articulation Aid 1) which aids human users in the formation of new concepts in the domain of engineering and science. From the viewpoint of concept formation, one main process of creation is divergent thinking in which broad alternatives are searched, and another process is convergent thinking in which a unique solution is sought. From the viewpoint of huma... View full abstract»

  • Merging strategic and tactical planning in dynamic and uncertain environments

    This paper presents a new approach to planning in dynamic and uncertain environments. Planning is viewed as a process in which an agent's long term goals are transformed into short term tasks and objectives, given the agent's strategy and the context of planning. The developed model allows for a dynamic balance between long term strategic planning and short term tactical planning. The notion of a ... View full abstract»

    An algorithm for the detection of dominant points and for building a hierarchical approximation of a digital curve is proposed. The algorithm does not require any parameter tuning and is shown to perform well for a wide variety of shapes, including scaled and rotated ones. Dominant points are first located by a coarse-to-fine detector scheme. They constitute the vertices of a polygon closely appro... View full abstract»

    This study investigates several possible causes for the finding that the human monitor tends to oversample low bandwidths and undersample high bandwidths in monitoring multiple processes. The results show that this finding may be related to a tendency to conditionally sample low bandwidths whereas high bandwidths tend to be periodically sampled View full abstract»

  • Analysis of delays in networked flight simulators

    Networking large numbers of manned flight simulators over wide geographical areas has become feasible because of the great advances in the technologies of microprocessors, and local area and long haul networks. One of the main concerns in developing networked simulators is the effect of intersimulator time delay on the performance of these networks as training devices. Previous studies on the effe...

  • Hand acceleration impulse bandwidth during target acquisition: implications for teleoperator bandwidth requirements

    The purpose of this experiment was to provide data about bandwidth requirements for teleoperators. During teleoperation, user inputs are changes in forces applied to the master controller arising from changes in hand acceleration during execution of goal-directed trajectories, so human hand acceleration bandwidth sets an upper bound on teleoperator feedforward bandwidth requirements.

  • Computational analysis of robot kinematics, dynamics, and control using the algebra of rotations

    The basic quantities required for computations in robot kinematics, dynamics, and control are defined. By modifying the rotational operator in terms of the Euler parameters and appropriately choosing the zero reference position, the method of the algebra of rotations becomes more efficient than the homogeneous transformation method for computing these basic quantities. As a result, the computation... View full abstract»
