This paper introduces a general model for both specifying and designing conferences. A major goal of the model is to be useful at both the specification and the design stage. The model follows an object-oriented approach. It is based on the different roles played by groups of conference attendants, and describes conference behaviour in term of role changes. Groups are defined at different abstr...

This paper proposes an adaptive method to balance cell voltages in alternating battery cell method. In the alternating battery cell discharg cells are periodically discharged in turn. Recovery effect increases battery output voltage while the given battery cell rests without discharging, thus battery operation time of targe However, voltage mismatch between cells leads voltage difference betwee...

We study the cost of multiplication modulo triangular families of polynomials. Following previous work by Li, Moreno Maza and Schost, we propose an algorithm that relies on homotopy and fast evaluation-interpolation techniques. We obtain a quasi-linear time complexity for substantial families of examples, for which no such result was known before. Applications are given to notably addition of a...
