    A system of N statistically identical machines is modeled using renewal theory through a unique architecture and state space. The model is very useful in evaluating flexible manufacturing systems (FMS) in particular. Each machine consists of multiple part types that are subject to individual failure. A multiple stage repair process composed of integrable sojourn time distributions requires access ... View full abstract»

    A textured image is considered to be produced by a smooth signal, representing in part the illumination environment, modulated by some frequencies determined by surface characteristics of the textures. Through expansion of the smooth signal into wavelets, a textured image may be decomposed into modulated “wavelets” providing multiresolution information. It is shown that the correspondi...

    The nonlinearity of the simplest fuzzy PI controller with different inference methods has been discussed and it shows that Mamdani's minimum inference method is the most general inference method for the fuzzy PI controller. In addition, a novel tuning method based on gain and phase margins has been proposed to determine the weighting coefficients of the fuzzy PI controllers. With the proposed tuni...

    Based on the concept of sliding mode control, the paper designs a fuzzy logic control for a linear system to achieve the trajectory tracking in the phase plane. That is, the system's state (e, e˙) is controlled to track the prespecified trajectory which is composed of several nonisoclinal segments. Each segment of the prespecified trajectory denotes the relation between the tracking error e an... View full abstract»

    This paper presents a procedure for automatically drawing directed graphs. Our system, Clan-based Graph Drawing Tool (CG), uses a unique clan-based graph decomposition to determine intrinsic substructures (clans) in the graph and to produce a parse tree. The tree is given attributes that specify the node layout. CG then uses tree properties with the addition of “routing nodes” to route... View full abstract»

  • Identification of incompletely specified multiple-valued Kleenean functions

    This paper focuses on incompletely specified multiple-valued Kleenean functions (1991). It is easy to verify that they do not have functional completeness in the class of all functions on the unit interval. Therefore, not all incompletely specified functions on the unit interval are incompletely specified multiple-valued Kleenean functions. In this paper, we will clarify a necessary and sufficient...

  • An annealing framework with learning memory

    Simulated annealing can be viewed as a process that generates a sequence of Markov chains, i.e., it keeps no memory about the states visited in the past of the process. This property makes simulated annealing time-consuming in exploring needless states and difficult in controlling the temperature and transition number. In this paper, we propose a new annealing model with memory that records import... View full abstract»

  • Nonlinear system input structure identification: two stage fuzzy curves and surfaces

    When modeling a complex, poorly defined, nonlinear problem with hundreds of possible inputs, we must identify the significant inputs before any known nonlinear modeling techniques can be applied. We introduce two stage fuzzy curves and surfaces and use them to 1) automatically and quickly order large numbers of inputs according to their significance, 2) eliminate spurious inputs, and 3) eliminate ...

  • Inferring new design rules by machine learning: a case study of topological optimization

    This paper presents a machine learning approach to the topological optimization of computer networks. Traditionally formulated as an integer program, this problem is well known to be a very difficult one, only solvable by means of heuristic methods. This paper addresses the specific problem of inferring new design rules that can reduce the cost of the network, or reduce the message delay below som... View full abstract»

    The visual appearance of an object in space is an image configuration projected from a subset of connected faces of the object. It is believed that face perception and face integration play a key role in object recognition in human vision. This paper presents a novel approach for calculating viewpoint consistency for three-dimensional (3D) object recognition, which utilizes the perceptual models o... View full abstract»

    Many important applications, such as graph coloring, scheduling and production planning, can be solved by GENET, a local search method which is used to solve binary constraint satisfaction problems (CSPs). Where complete search methods are typically augmented with consistency methods to reduce the search, local search methods are not. We propose a consistency technique, lazy arc consistency, which...

    Fuzzy propositional logic structure is summarized; different forms of fuzzy propositional expressions and their relations are discussed. Two-sided fuzzy proposition is defined in propositional logic algebra as the counterpart of intuitionistic fuzzy set. The concept of two-sided fuzzy reasoning is discussed and its mathematical structure is developed. Using two-sided fuzzy propositions, human deci... View full abstract»

  • Obstacle avoidance in a dynamic environment: a collision cone approach

    A novel collision cone approach is proposed as an aid to collision detection and avoidance between irregularly shaped moving objects with unknown trajectories. It is shown that the collision cone can be effectively used to determine whether collision between a robot and an obstacle (both moving in a dynamic environment) is imminent. No restrictions are placed on the shapes of either the robot or t... View full abstract»

    Many real applications of Bayesian networks (BN) concern problems in which several observations are collected over time on a certain number of similar plants. This situation is typical of the context of medical monitoring, in which several measurements of the relevant physiological quantities are available over time on a population of patients under treatment, and the conditional probabilities tha...

    Knowledge representation is one of important factors that determine human performance on cognitive tasks. Due to different levels of experience, different groups of people may develop different knowledge representations which lead to different levels of performance on cognitive tasks. If knowledge representation differences exist between skill groups such as experts and novices, those differences ... View full abstract»

    We present, analyze, and numerically evaluate extended algorithms for detecting changes from an acting stochastic process to a number of possible alternatives. The algorithms are sequential, requiring minimal memory capacity and operational complexity, and they incorporate decision thresholds. The performance of the algorithms is controlled by the selection of the thresholds. Asymptotically, the f... View full abstract»

  • An invariant performance measure for surface reconstruction using the volume between two surfaces

    In this paper, we propose the volume between two surfaces normalized by the surface area (interpreted as average distance between two surfaces) as an invariant quantitative measure for comparing surface reconstruction results of the explicit form, z(x,y). The invariant property of the volume quantity provides the same measure with respect to an arbitrary coordinate system. By normalizing the volum... View full abstract»
