Can recessions, or serious turning points in general, be predicted? Or do forecasters tend to assume that the future will continue as an extension of the near past. Theoretical evidence and practical observations tend to ...

Les lois de développement qui ont été périodiquement mises en oeu v re en Grèce n'ont pas toujours comporté d'incitations fin a ncières. Cette absence pouvait s'expliquer de plusieurs manl eres, soi t que l'on ait préféré ...

This paper deals with a new low level feature that is extracted from the images and can be used for indexing and retrieval. This feature is called “Color and Edge Directivity Descriptor” and incorporates color and texture ...

During the last decades much attention was given to bio-inspired techniques able to successfully handle really complex algorithmic problems. As such Ant Colony Optimization (ACO) algorithms have been introduced as a ...

Various studies have employed quantitative and qualitative methods in order to explore the process of behavioral change emerging during a drug addiction treatment, i.e. the factors both encouraging and discouraging such ...

How successful have economists and other business forecasters been in predicting recessions? This question is of considerable practical value since the level of economic activity greatly influences budgets and other plans ...

The classification of uses is one of the central issues of urban planning, since it is only by referring to groups of uses that we can achieve the simplification and, ultimately, the understanding of urban space. However, ...

In classical statistics, inferences about the popula- tion mean, confidence intervals, or testing of hypoth- eses are based on the sampling distribution of X. For the statistician or the mathematically sophisticated, there ...

Due to the rapid development of information technology and the continuously increasing number of available multimedia data, the task of retrieving information based on visual content has become a popular subject of scientific ...

Recent studies have strongly criticised conventional VaR models for not providing a coherent risk measure. Acerbi provides the intuition for an entire family of coherent measures of risk known as “spectral risk measures” ...

Image indexing refers to describing the visual multimedia content of a medium, using high level textual information or/and low level descriptors. In most cases, images and videos are associated with noisy and incomplete ...

Aggregating information by combining forecasts from two or more forecasting methods is an alternative to using just a single method. In this paper we provide extensive empirical results showing that combined forecasts ...

In this paper, a novel low level feature for content based image retrieval is presented. The proposed feature structure combines color and spatial color distribution information. The combination of these two features in ...

In the context of Linked Data (LD) sources, the ability to traverse links and retrieve further information can be exploited to harvest semantic annotations. Such annotations can, in turn, underpin the inference of semantic ...

The epigram "Είς τόν εαυτού πατέρα" by John Geometres is considered a lyrical sepulchral poetic masterpiece, since it densely captures the poet's emotional state within 11 lines. The particular epigram has already been ...

In 1982, the Journal of Forecasting published the results of a forecasting competition organized by Spyros Makridakis (Makridakis et al., 1982). In this, the ex ante forecast errors of 21 methods were compared for forecasts ...

This paper studies different types of commitment policy in an economy where the deterministic steady state is inefficient. We show how a policy suggested by the approach of policy design entails positive long-run inflation, ...

Comunication is onc of the most widely used and least understood concepts current among managerof modern corporations.

This article analyzes whether communication can solve all management problems. With the rapid technological developments in methods of communication, corporate managers have become more increasingly dependent on electronic ...

Low level features play a vital role in image retrieval. Image moments can effectively represent global information of image content while being invariant under translation, rotation, and scaling. This paper briefly presents ...
