Soft set, as a parametrized family of subsets of a crisp universal set, has more ability to handle uncertain information. In this paper, we propose two types of similarity measure between soft sets and made a comparative study of these two techniques. Also we have shown an application of this...

In many regions karstic aquifers constitute the only available source of drinking water. Due to the high risk of contamination in these aquifers, a comprehensive groundwater protection and control system must be designed and established. It has recentlybeen proposed that Hydrogeologic Reserve...

The paper combines hydrographic surveying techniques with numerical modelling to evaluate the spatial and temporal distributions of tidal power in a confined channel located in Portugal (Faro Channel in the Ria Formosa). The channel is characterised by strong currents with depth-averaged...

In this paper, we present the steady-state system-length distributions at intermediate, outside observer’s, post-departure and pre-service completion epochs for the GI/Geo/1 queue. It is also shown that in the limiting case, the results given in this paper tend to the continuous-time counterpart.

Forecasting failure events is one of the most important problems in fracture mechanics and related sciences. In this paper, we use the Molchan scheme to investigate the error diagrams in a fracture model which has the notable advantage of displaying two completely different regimes according to...

For a simple queue with finite waiting space the difference equations satisfied by the Laplace transforms of the state probabilities at finite time are solved and the state probabilities have been obtained. The method economizes in algebra and the simple closed form of the state probabilities is...
