    An experimental design approach that treats the gray-level value of each pixel as an observation is proposed. Any pixel corrupted by salt-and-pepper noise is considered to be a missing observation. An estimate of a missing observation is derived using a 5×5×5×5 Graeco-Latin squares experimental design model fitted to a 5-pixel×5-pixel mask. Edge-preserving smoothing of imag...

    An identification method for determining the inertial parameters of robot manipulators with closed kinematic chains is presented. The main issues are the mathematical model describing the robot system, the derivation of a dynamic model using linear combinations of the inertial parameters, and the proposed identification algorithm. An illustrating example, using the proposed method for a closed-cha... View full abstract»

    A fast procedure for the computation of manipulator inverse kinematics and pseudoinverse robustness is presented. The approach is based on solving a linear algebraic system and evaluating the norm of the Jacobian matrix. This value is properly used in an original scheme that is also proposed for the appropriate robustness of the pseudoinverse matrix. The developed algorithm is tested on the simula...

    An approach to the synthesis and use of operational knowledge in diagnostic problem solving is proposed. The approach significantly departs from previous approaches to knowledge compilation in the sense that the authors do not aim at compiling an autonomous heuristic problem solver from a deep one but only at deriving a set of conditions whose evaluation can focus and speed up diagnostic reasoning...

    An approach to the representation of signatures in an offline environment that makes a tracing of a signature in a manner similar to that of a human normally does, and incorporates the dynamic information of the tracing sequence into the representation of the signature, is presented. Tracing involves hierarchical decision-making for stroke identification and ordering based on a set of heuristic ru... View full abstract»

    An approach to strategic recognition of objects using multiple sensors based on the candidate discriminating graph (CADIG) is presented. A CADIG represents the candidates of an unknown object and the complete discriminating relations between the candidates in terms of relevant discriminators (geometric features). Strategic recognition is decomposed into two interacting procedures: the information ... View full abstract»

    A hierarchical data structure for analyzing visual motion is presented. Although the literature on perception is abundant with studies on visual motion, none of the studies investigated the importance of a hierarchical model in the analysis of visual motion. The model was implemented on a supercomputer (Cyber 205). The algorithms of hierarchical correlation were performed on binary images. The res... View full abstract»

    The choice of an optimal action in a decision-making problem involving fuzzy utilities has been reduced in most previous studies to modeling the fuzzy utilities and the expected fuzzy utility and selecting a technique for ranking fuzzy numbers that fits the situation. A new element is incorporated in the decision problem, namely, the sample information supplied by a random experiment associated wi... View full abstract»

    Some common algorithms for regular grammatical inference with different regular grammars have been tested in order to clarify how they can consider those languages. The methods of so-called successor, canonical derivative, k-tails, tail-clustering, and skeleton have been examined experimentally. The two last-mentioned methods were shown to be the best and the most general when inferring r... View full abstract»

    A theoretical framework for designing interfaces for complex human-machine systems is proposed. The framework, called ecological interface design (EID), is based on the skills, rules, and knowledge taxonomy of cognitive control. The basic goals of EID are not to force processing to a higher level than the demands of the task require, and to support each of the three levels of cognitive control. Th... View full abstract»

    One of the most important problems in random testing is the measurement of test confidence after a sequence of test vectors has been applied. Sequential statistical analysis is employed to determine the random test confidence. According to the analysis, the random test confidence depends on the detection probability of the circuit under test, the random test length, and the manufacturing yield. A ... View full abstract»

    Diagrams are used to facilitate problem solving in engineering, physics, geology, and other scientific areas. Diagrams store related elements adjacents to each other. For instance, it can be easily seen from a map that Iowa and Illinois are adjacent states, since they are placed next to each other. A nondiagrammatic or sentential representation of the map would have this information explicitly cod... View full abstract»

    Learning from examples uses specific instances (examples and counterexamples) to produce general rules. It is a convenient learning scheme in cases where the process of interviewing human experts and analyzing and formalizing their decision is very difficult or time consuming.

    An active wide-beam sonar system that mimics the sensor configuration of echolocating bats is described for applications in sensor-based robotics. Obstacles in a two-dimensional (2-D) environment are detected and localized using time-of-flight (TOF) measurements of their echoes. The standard threshold detector produces a biased TOF estimate. An unbiased TOF estimate is derived by a parametric fit ... View full abstract»

    Redundant robots that are kinematically controlled by using Jacobian pseudoinverses may not have repeatable joint motions. This problem was initially observed and analyzed by C.A. Klein and C.H. Huang (1983). T. Shamir and Y. Yomdin (1988) analyzed this problem using a differential geometric approach. Both studies arrived at conditions under which a cyclic path in the work space does not result in... View full abstract»
