The centered OWA (C-OWA) operator weights, defined as the center point of a convex hull constructed by the extreme points of ordinal relation, are computed by coordinate-wise averaging of the extreme points. The resulting C-OWA operator weights display some interesting properties. First there exists one to one correspondence between the multiplier used in the ordinal relation and the attitudinal character,...
This paper addresses the problem of supply chain tactical planning under uncertainty and perturbation. Uncertainty is defined according to future data and perturbation is detected according to past decisions. We develop an approach based on successive planning steps (rolling horizon procedure). For each planning step, data is updated and real implemented decisions are taken into account. To deal with...
The paper concerns approximate dynamic decision making. It deals with solving Bellman equation to obtain the Bellman function via so-called suboptimal strategies. The sub-optimal strategies are strategies reflecting the revision of the realized past decisions. The revision is conditioned on availability of future knowledge. Suboptimal strategies help to transform the estimation of Bellman function...
In this paper, an implementation of fuzzy similarity methods for model based manipulative hand postures is presented. The model used to represent manipulative hand postures is based on a human hand kinematical model. In the model, the posture is formed as a set of hand joint variables. Joint angles of the posture are fuzzified to obtain a Fuzzy superset, which is used to obtain the symbolic posture...
This paper describes a Brain-Computer Interface (BCI) based on electroencephalography (EEG). This BCI registers the brain rhythmic activity through 16 electrodes situated on the scalp and differentiates three cognitive processes. The Wavelet Transform (WT) has been used to extract the features. In order to differentiate three mental tasks, two Linear Discriminant Analysis (LDA) based classifiers have...
Based on the field survey data of Kishiwada City, Osaka, Japan, this paper analyzes the potential role of social capital developed through ritual events in building a disaster resilient community. The preliminary findings show that the ritual events are contributing to the development of trust in the community at Kishiwada. Bonding social capital, bridging social capital and trust are found to enhance...
