Thus, in this paper Fuzzy Cognitive Maps are explored to represent the behaviour and operation of such systems. This technique allows modelling how the travellers make decisions based on their knowledge of different transport modes properties at different levels of abstraction. We use learning of Fuzzy Cognitive Maps to describe travellers' behaviour and change trends in different abstraction levels. The results of this study will help transportation policy decision makers in better understanding of people's needs and consequently will help them actualizing different policy formulations and implementations.

The MPEG 7 descriptors give a good presentation of different types of visual features, but are complex structures. This prevents their direct use into standard classification algorithms and thus requires specific processing. Our approach consists of the following steps:(1) the images are tiled into non-overlapping rectangles to capture more detailed information;(2) the tiles of the images are clustered for ...

The approach consists of the following steps:(1) tiling images into non-overlapping rectangles in order to capture more detailed local information;(2) the tiles of the images are clustered for each MPEG-7 descriptor;(3) vector quantization is used to assign a unique value to each tile, which corresponds to the ...

The authors contribute to this literature by extending and refining previous family firm typologies. To attain this objective, the authors introduce the professionalization construct as basis for distinguishing family firms. As this construct is often approached in an oversimplified, one-dimensional manner, they first conduct an exploratory factor analysis to reveal its multidimensional nature. Based on these results, drawn from a representative sample of 532 Belgian family businesses, a cluster analysis facilitates a distinction between different “types” of family firms based on a multidimensional conceptualization of firm professionalization.
