Kinematics of Complex-Valued Time Series
The contribution to a stationary complex-valued time series at a single frequency magnitude takes the form of a random ellipse, and its properties such as aspect ratio (which inclu...

Real Time, Accurate, Multi-Featured Rendering of Bump Mapped Surfaces
We present a new technique to render in real time objects which have part of their high frequency geometric detail encoded in bump maps. It is based on the quantization of normal-...

Optimal infinite scheduling for multi-priced timed automata
Abstract. This paper is concerned with the derivation of infinite schedules for timed automata that are in some sense optimal. To cover a wide class of optimality criteria we start...

On the Compared Expressiveness of Arc, Place and Transition Time Petri Nets
In this paper, we consider safe Time Petri Nets where time intervals (strict and large) are associated with places (P-TPN), arcs (A-TPN) or transitions (T-TPN). We give the formal ...
