    We present an approach for the design and control of both reflexive and purposive visual tasks. The approach is based on the bidimensional appearance of the objects in the environment and explicitly takes into account independent object motions. A linear model of camera-object interaction is embedded in the control scheme, which dramatically simplifies visual analysis and control by reducing the s... View full abstract»

    Systems analysis is applied to a milieu of sports rating systems (SRSs) resulting in a unifying taxonomy. Each SRS operates in three phases: evaluation of sports performance, weighting of the evaluated performance and creation of a rating for each competitor using the weighted evaluated performance. In the first phase, sports are classified as: combat sports where each competitor tries to control ... View full abstract»

    A key factor in the management of software projects is the ability of the manager to handle delays in the hiring and assimilation of staff. This study examines how decision makers cope with staffing delays, and how their decisions affect the outcome of software projects. We report the findings of a laboratory experiment in which subjects managed a simulated software project that entailed delays in... View full abstract»

    The evaluation of information systems is often conducted using performance measures developed by the system designers. Still, other categories of measures exist, including those that match the system to the desires of the user, the climate of the organization, and the decision quality. This study looks at the importance to the user of different evaluation categories for three system types. Finding... View full abstract»

  • Minimal representation multisensor fusion using differential evolution

    Fusion of information from multiple sensors is required for planning and control of robotic systems in complex environments. The minimal representation approach is based on an information measure as a universal yardstick for fusion and provides a framework for integrating information from a variety of sources. In this paper, we describe the principles of minimal representation multisensor fusion a... View full abstract»

  • Hierarchically merging plans in decomposable domains

    Publication Year: 1999, Page(s):27 - 40
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (328 KB)

    Recent works in domain-independent plan merging have shown that the optimal plan merging problem is NP-hard, and heuristic algorithms have been proposed to generate near-optimal solutions. We have developed a plan merging methodology that merges partial-order plans based on the notion of plan fragments. In contrast to previous works, mergeability classes no longer necessarily form a partition over... View full abstract»

    Gibson's ecological approach to perception has recently received significant attention in the robotics literature, The approach relies on the identification and application of affordances for a behaviour. However, determining suitable affordances has been treated as an art rather than a science. This paper presents a methodology for deciding whether an affordance-based approach should be pursued f...

    The optimization of fuzzy systems using bio-inspired strategies, such as neural network learning rules or evolutionary optimization techniques, is becoming more and more popular. In general, fuzzy systems optimized in such a way cannot provide a linguistic interpretation, preventing us from using one of their most interesting and useful features. This paper addresses this difficulty and points out... View full abstract»

    A binary distributed detection system comprises a bank of local decision makers (LDMs) and a central information processor or data fusion center (DFC). All LDMs survey a common volume for a binary {H0, H1} phenomenon. Each LDM forms a binary decision: it either accepts H1 (target-present) or H0 (target-absent). The LDM is fully characterized by its perf... View full abstract»

    In this paper, we first present the formulation and solution of the basic test sequencing problem. We then consider generalized test sequencing problems that incorporate various practical features such as precedence constraints and setup operations for tests, multi-outcome tests, modular diagnosis, and rectification. We develop various AO* and information heuristic-based algorithms to ... View full abstract»

    This paper presents a linear assignment algorithm for solving the clustering problem. By using the most dissimilar data as cluster representatives, a linear assignment algorithm is developed based on the linear assignment model for clustering multivariate data. The computational results evaluated using multiple performance criteria show that the clustering algorithm is very effective and efficient... View full abstract»

    This paper suggests an intelligent controller for an automated vehicle planning its own trajectory based on sensor and communication data. The intelligent controller is designed using the learning stochastic automata theory. Using the data received from on-board sensors, two automata (one for lateral actions, one for longitudinal actions) can learn the best possible action to avoid collisions. The... View full abstract»

    In redundancy optimization problems related to cooperating manipulators such as optimal force distribution, constraints on the physical limits of the manipulators should be considered. We propose quadratic inequality constraints (QICs), which lead to ellipsoidal feasible regions, to solve the optimization problem more efficiently. We investigate the effect of the use of QICs from the points of vie... View full abstract»

    In this paper, we consider a new approach to fuzzy control which entails the formulation of a novel state-space representation and a new form of optimal control problem. Basically, in this new formulation, linear functions in the conventional state-space representation and cost functional are replaced by hyperbolic functions. We give a solution for this new, infinite-time, optimal control problem,... View full abstract»

    This paper introduces a new algorithm for quickly answering repetitive least-cost queries between pairs of points on the Earth's surface as represented by digital topographical maps. The algorithm uses a three-step process; preprocessing, geometrically modified Dijkstra search, and postprocessing. The preprocessing step computes and saves highly valuable global information that describes the under... View full abstract»
