Data mining, also known as "discovery knowledge in large databases "is a modern and powerful information technology and communications tool that can be used to extract useful information but still unknown. This automates the process of discovery some relations and mixtures from the raw data and...

Labor force mobility is an increasingly important component of contemporary society and equally adjustment tool imbalances in labor markets. The phenomenon of labor mobility is nowadays the most dynamic form of movement of potentially active population. Using cluster analysis this paper aims to...

The aim of this research is to study life quality using the cluster analysis methodology. The analysis includes a number of classifing algorithms of elements into relatively homogenous groups and makes a global analysis of statistical units using a high number of characteristics. The required...

The analysis of social indicators and the analysis of life quality are very important in order to know, in time, the changes of the main social and economic phenomena that characterize a society. To monitor the social system is a priority of modern societies because it helps to identify in time...

Purpose The purpose of this paper is to derive crucial insights from multi-scale analysis to detect equity return co-movements between Korean and emerging Asian markets. Design/methodology/approach Wavelet correlation, wavelet coherence and wavelet clustering measures are used to uncover Korean...

We are given a bipartite graph G = (A B;E) where each vertex has a preference list ranking its neighbors: in particular, every a A ranks its neighbors in a strict order of preference, whereas the preference list of any b B may contain ties. A matching M is popular if there is no matching M' such...

Stable flows generalize the well-known concept of stable matchings to markets in which transactions may involve several agents, forwarding flow from one to another. An instance of the problem consists of a capacitated directed network in which vertices express their preferences over their...

Our input is a complete graph G on n vertices where each vertex has a strictranking of all other vertices in G. The goal is to construct a matching in G that is "globallystable" or popular. A matching M is popular if M does not lose a head-to-head election againstany matching M': here each...
