A new approach for estimating null value in relational database
In general, a database system will not operate properly if it exist some null values of attributes in the system. In this paper, we propose a new approach to estimate null values in relational database, which ...

Flexible fuzzy OWA querying method for hemodialysis database
The hemodialysis quality contains the subjective opinions of the physicians. However, the range of good/bad quality of one physician’s perspective usually differs from the others, so we use the fuzzy theory to...

The Patterns of Surface Capillary-gravity Short-crested Waves with Uniform Current Fields in Coastal Waters
A fully three-dimensional surface gravity-capillary short-crested wave system is studied as two progressive wave-trains of equal amplitude and frequency, which are collinear with uniform currents and doubly-pe...
