it is well known that damaged structural members may alter the behaviour of the structures considerably. careful observation of these changes has often been viewed as a means to identify and assess the location and severity of damages in structures. among the responses of a structure, natural frequencies and natural modes are both relatively easy to obtain and independent from external excitati...

f rom the viewpoint of economic theories, total factor productivity (tfp) is the most important component that leads to economic growth and development. the main purpose of this study was to evaluate the impact of knowledge-based economy on total factor productivity in the member countries of the middle east and north africa (mena) region. for this purpose, the panel data regression analysis ha...

data grids support access to widely distributed storage for large numbers of users accessing potentially many files. to enhance access time, replication at nearby sites may be used. data replication, a technique much investigated bydata grid researchers in past years creates multiple replicas offile and places them in conventional locations to shorten fileaccess times. one of the problems in da...

data grid is an infrastructure that controls huge amount of data files, and provides intensive computational resources across geographically distributed collaboration. the heterogeneity and geographic dispersion of grid resources and applications place some complex problems such as job scheduling. most existing scheduling algorithms in grids only focus on one kind of grid jobs which can be data...

The Urbanopoly datasets contain the results of a data curation campaign on available geospatial open datasets like OpenStreetMap. The curation effort is conducted through a location-based Game with a Purpose inspired by the monopoly board game. The paper describes the generated datasets: we illustrate the genesis and life-cycle of Urbanopoly data; we explain the modelling choices by introducing...
