However, in spite of this importance, it is difficult to conserve these assets. In the case of performances and non-artefactual cultural assets, information is apt to disappear almost immediately after the initial performance. The same is true of ...

In order to evaluate the performance of socially responsible investment (SRI) funds, we propose some models which use data envelopment analysis and can be computed in all phases of the business cycle. These models focus on the most crucial elements of an investment in mutual funds. In the literature both constant and variable returns to scale DEA models have been used to evaluate the performanc...

The paper presents a new study method of mechanic vibrations with the help of the data acquisition systems. The study of vibrations with the help of data acquisition systems allows the solving of some engineering problems connected to the measurement of some parameters which are difficult to measure having in view the improvement of the technical performances of the industrial equipment or devi...

This paper presents a data envelopment analysis (DEA) model combined with Bootstrapping to assess performance of one of the Data mining Algorithms. We applied a two-step process for performance productivity analysis of insurance branches within a case study. First, using a DEA model, the study analyzes the productivity of eighteen decision-making units (DMUs). Using a Malmquist index, DEA deter...

1. Background The growth in computing power, storage, and networking has encouraged and enabled an increasing interest in big data, which one might define as volumes beyond what any individual researcher can collect and analyze directly. In linguistics, this naturally leads to increased emphasis on data sharing, which is one way to amass data of sufficient size and variety to permit new kinds o...

This study investigates the issue of the goodness of fit of different skills assessment models using both synthetic and real data. Synthetic data is generated from the different skills assessment models. The results show wide differences of performances between the skills assessment models over synthetic data sets. The set of relative performances for the different models create a kind of “sign...
