The problems of power and energy shortage (natural or associated with the advisability of load management) allocation at different levels of territorial, temporal, and situational hierarchy of consumption control are formulated within the framework of multicriteria optimization models. This permits one to realize a new technology of load management providing consideration and minimization of diverse negative consequences of power and energy shortage allocation and creation of incentive influences for consumers. The solution of multicriteria problems is based on the Bellman-Zadeh approach to decision making in a fuzzy environment. The advantages and capabilities opened by its application are discussed. The results of the paper are realized within the framework of an adaptive interactive decision making system, which can be used in allocating diverse types of resources or their shortages.

This paper presents results of research aimed at improving efficiency of coordinated on-line control of reactive power on the basis of developing models, methods, and a control system, integrating traditional numerical techniques with fuzzy logic technology. An approach associated with experimental design is considered to construct diverse types of sensitivity indices, which serve as the basis for multi-attribute evaluating efficiency of control actions and, therefore, for forming rules included in a knowledge base. Procedures related to classifying power system states are presented. Questions of the construction and tuning of linguistic variables as well as rational implementation of fuzzy logic procedures are discussed.

We propose a new evaluation method IPL (Island formation using Pseudo Label), and show its efficiency. In IPL method, the effects of domain knowledge of each participant can be evaluated based on an intuitive classification task in a distributed and cooperative KJ method. Experiments using IPL method show the influences upon the island formation caused by the distribution of knowledge quantitatively. There exists a similar method called LCR method which provides an evaluation method for the logical classification tasks. However the proposed IPL method provides an evaluation method for the intuitive classification tasks by which the creation of new idea can be done easily and effectively.

Ship design is often multidisciplinary involving several design elements with various types of objectives and constraints (O/C) some easily described as mathematical formulas, others better modeled as descriptive assertions. This paper describes a method based on fuzzy functions and an integrated performance index to model O/C using descriptive assertions to be used with mathematical formulas in optimization. Another issue addressed in this paper concerns the coordination of design elements when sequentially coupled, that is, when one leads the other and the performance of the follower depends greatly on the design of the leader. Based on neuro-fuzzy techniques, the method described here coordinates and optimizes sequentially coupled elements. The two methods are applied to machinery arrangement (MA) and pipe routing (PR). Preliminary models for optimization of MA and PR are described considering convenience, producibility: engine room size, interference and location as factors in the O/C set. Some test results from MA/PR applications are presented and discussed. The methods are generic and can be extended to other elements in ship design. They are mutually independent and may be used separately Two advantages of their use are an improvement in overall performance and a reduction in the need for redesign of elements.

Subtrellises for low-weight codewords of binary linear block codes have been recently used in a number of trellis-based decoding algorithms to achieve near-optimum or suboptimum error performance with a significant reduction in decoding complexity. An algorithm for purging a full code trellis to obtain a low-weight subtrellis has been proposed by H.T. Moorthy el. al. This algorithm is effective for codes of short to medium lengths, however for long codes, it becomes very time consuming. This paper investigates the structure and complexity of low-weight subtrellises for binary linear block codes. A construction method for these subtrellises is presented. The state and branch complexities of low-weight subtrellises for Reed-Muller codes and some extended BCH codes are given. In addition, a recursive algorithm for searching the most likely codeword in low-weight subtrellis-based decoding algorithm is proposed. This recursive algorithm is more efficient than the conventional Viterbi algorithm.

The present paper deals with the co-learnability of enumerable families L of uniformly recursive languages from positive data. This refers to the following scenario. A family L of target languages as well as hypothesis space for it are specified. The co-learner is fed eventually all positive examples of an unknown target language L chosen from L. The target language L is successfully co-learned iff the co-learner can definitely delete all but one possible hypotheses, and the remaining one has to correctly describe L. The capabilities of co-learning are investigated in dependence on the choice of the hypothesis space, and compared to language learning in the limit, conservative learning and finite learning from positive data. Class preserving learning (L has to be co-learned with respect to some suitably chosen enumeration of all and only the languages from L), class comprising learning (L has to be co-learned with respect to some hypothesis space containing at least all the languages from L), and absolute co-learning (L has to be co-learned with respect to all class preserving hypothesis spaces for L) are distinguished. Our results are manyfold. First, it is shown that co-learning is exactly as powerful as learning in the limit provided the hypothesis space is appropriately chosen. However, while learning in the limit is insensitive to the particular choice of the hypothesis space, the power of co-learning crucially depends on it. Therefore the properties a hypothesis space should have in order to be suitable for co-learning are studied. Finally, a sufficient conditions for absolute co-learnability is derived, and it is separated from finite learning. © Springer-Verlag Berlin Heidelberg 1996.

The formation process as well as the characteristics of a surface oxidized layer formed on Al-Y alloy films are examined. Al in the alloy forms a thin Al2O3 layer due to more oxidation Pt the alloy surface. In an alloy of Al-rich composition, if the Al2O3 surface layer (which is comparable to that formed on pure Al) is formed, the layer maintains its ability to be a self-passivating oxide layer. In those alloys that form an unduly thin Al2O3 surface layer, introduction of oxygen from the ambient environment cannot be curtailed. As a result, oxidation proceeds and the formation of Y2O3 and reduced Al is observed within the oxide layer. In the oxidized layer, the oxidation state of the lesser amount of oxide is affected by that of the greater amount oxide;this reflects a shift in binding energy of the XPS spectra for the minor element. It is shown that the formation process of the alloy is dominated by the differences of ionization potential, an element affinity, formation heat, a diffusing species and the transport behavior of cations and/or anions.

An asymptotic method of analysis is studied for the radiation field when the lowest-order whispering gallery (WG) modes propagating from the concave side of the concave-to-convex boundary with a variable radius of curvature are radiated into the free-space on the convex side. The modal ray congruences of the WG mode are radiated into the free space after being converted to geometrical rays. Both the caustics and the shadow boundaries are created in the space. As the expression of the radiated field near the caustic, the modal rays incident into the concave part are used for deriving the physical optics integral. By applying the high-frequency asymptotic analysis in the case of two saddle points closely spaced to the evaluation of the integral, the uniform asymptotic solution was derived. Also, as the radiating field on the sufficiently shadow side of the caustic, the complex ray solution was derived. On the other hand, as the radiating field in the transition region near the shadow boundary caused by the convex region, an asymptotic solution was derived in the form of an extension of the conventional UTD (Uniform GTD) to the case where the geometrical ray converted from the modal ray is incident to the boundary. The numerical results obtained by various asymptotic expressions are compared with the reference solution and the geometrical optics figure drawn by the modal ray tracing. The effectiveness of the asymptotic solution and the propagation and radiation phenomena of the WG mode were derived.
