In decisional systems framework, my thesis focuses on the conception and the querying of multidimensional data.We provide a dimensional model organising data in a constellation of facts (subject of analysis) associated withdimensions (axes of analysis). These dimensions are flexible because each dimension instance can belong to oneor several hierarchies (perspectives of analysis...

In this paper, we propose a new technique for multidimensional query processing which can be widely applied in database systems. Our new technique, called tree striping, generalizes the well-known inverted lists and multidimensional indexing approaches. A theoretical analysis of our generalized technique shows that both, inverted lists and multidimensional indexing approaches, are far from bein...

The factor structure of the Multidimensional Health Locus of Control scale remains in question. Additionally, research on health belief differences between Black and White respondents suggests that the Multidimensional Health Locus of Control scale may not be invariant. We reviewed the literature regarding the latent variable structure of the Multidimensional Health Locus of Control scale, used...

Based on the multidimensional uncertain optimal control problem with jump, in this paper, a kind of special multidimensional uncertain optimal control problem: multidimensional uncertain linear-quadratic (LQ) optimal control problem with jump which has a quadratic objective function for a multidimensional uncertain linear control system with jump is studied. A necessary and sufficient condition...

This paper provides an answer-oriented multidimensional analysis environment. The approach is based on a conceptual point of view. We define a conceptual model that represents data through a constellation of facts and dimensions and we present a query algebra handling multidimensional data as well as multidimensional tables. Based on these two propositions, in order to ease the specification of...

This paper explores the axiomatic foundation of multidimensional poverty indices. Departing from the income approach which measures poverty by aggregating shortfalls of incomes from a predetermined poverty-line income, a multidimensional index is a numerical representation of shortfalls of basic needs from some pre-speci®ed minimum levels. The class of subgroup consistent poverty indices introd...

Large-scale scientific experiments or simulation programs often generate large amounts of multidimensional data. Data volume may reach hundreds of terabytes (up to petabytes). In the present and the near future, the only practicable way for storing such large volumes of multidimensional data is tertiary storage systems. But commercial (multidimensional) database systems are optimized for perfor...

In MIMO communications systems, the data has a natural multidimensional structure composed of time, frequency and space dimensions. Recently, multidimensional techniques that take into account the data multidimensional structure have been proposed for model order selection, parameter estimation and prewhitening. These multidimensional techniques require an array with a PARAFAC structure. Howeve...
