We propose a multidimensional approach to regional inequality as an alternative allocation mechanism for EU Structural Funds remittances based on per capita GDP, particularly after EU enlargement. The indicators of regional inequality are combined to a composite index by means of Maasoumi’s aggregator function. We propose Partial Common Principal Component Aanalysis as the estimator of the weig...

Point-transformation schemes transform multidimensional points to one-dimensional values so that conventional access methods can be used to index multidimensional points, enabling convenient integration of multidimensional query facilities into complex transactional database management systems. However, in high-dimensional data spaces, the computational complexity of the required query transfor...

We present a new implementation scheme of multidimensional array for handling large scale high dimensional datasets that grows incrementally. The scheme implements a dynamic multidimensional extendible array employing a set of two dimensional extendible arrays. The multidimensional arrays provide many advantages but it has some problems as well. The Traditional Multidimensional array is not dyn...

Near neighbor searching in image databases is a multidimensional problem. The kd-tree is one of the first methods proposed for indexing multidimensional data. We describe optimizations of this method, and determine when they are appropriate. We discuss adaptations of the tree to feature extraction and indexing problems in multimedia data. Results show increased functionality and speed using the...

In this note we show how to introduce physical constraints in the localization problem in sensor networks. This is based on extending the classical STRESS function from distance geometry and multidimensional scaling. We present the underlying framework and demonstrate it with three examples: penalizing the sensors for being in high elevation areas, removing sensors from forbidden areas, and for...

BACKGROUND Chronic obstructive pulmonary disease (COPD) is considered to be a respiratory disease with systemic manifestations. Some multidimensional staging systems, not based solely on the level of airflow limitation, have been developed; however, these systems have rarely been compared. METHODS We previously recruited 150 male outpatients with COPD for an analysis of factors related to mor...

This paper investigates a self-organizing map algorithm which is simultaneously given multiple inputs, and introduces a criterion of ordering process as the twist measurement for reference vectors in multidimensional array. The self-organizing algorithm and the criterion are termed the parallel self-organizing algorithm and the index of twist, respectively. The algorithm updates reference vecto...

The multidimensional view of well-being is receiving growing attention, both in academic research and policy-oriented analysis. This paper examines empirical strategies to measure poverty and inequality in multiple domains, concentrating on two problems in the use of synthetic multidimensional indices: the weighting structure of different functionings and the functional form of the index. These...

In this paper, we propose a new metric index, called M-tree, which is a tree dynamically organized for large datasets in metric spaces. The proposed M-tree takes full advantages of M-tree and MVP-tree, with a new concept called key dimension, which effectively reduces response time for similarity search. The main idea behind the key dimension is to make the fanout of tree larger by partitioning...
