GLOWA Volta Phase III -- Sustainable water use under changing land use patterns, rainfall reliability and water demand in the Volta Basin. The GLOWA Volta Project is an interdisciplinary project supporting sustainable water resource management in the Volta Basin. Main aim is the development of a Decision Support System (DSS) that will help the authorities in Ghana, Burkina Faso and the other riparian countries to optimize water allocation within the basin.

EDIP Fuzzy Expert System Shell (Windows 3.x) 
A simple fuzzy expert system shell based on the notion of fuzzy attribute model and using the method of fuzzy sectioned matrices for knowledge representation and logical inference. Download (102,718 bytes). Screenshot

Chelovek Rule induction system for Win'95 (DAO 3.5 is required). 
This system implements an original approach to rule induction based on the procedure of generation of prime disjunctions described here. Download.

FCalc Fuzzy Calculator (Screenshot)
A toy program simulating an ordinary calculator but using numbers from the interval [0,1] and a T-norm and conorm as operations. The operation of multiplication is defined as follows: 
        i(x,y) = log_s [1 + (s^x-1)(s^y-1)/(s-1)], 
where s is a parameter of the operation (set in the About dialogue). In particular, if s=0, i(x,y)=min(x,y); if s=1, i(x,y)=xy; if s=infinity, i(x,y)=max(0,x+y-1). Download (17,094 bytes)
