Pregroup Grammars with Letter Promotions
We study pregroup grammars with letter promotions p(m) q(n) . We show that the Letter Promotion Problem for pregroups is solvable in polynomial time, if the size of p(n)

Exact Runtime Analysis Using Automata-Based Symbolic Simulation
In this paper, we present a technique for determining tight bounds on the execution time of assembler programs. Thus, our method is independent of the design flow, but takes into...

A MAP IIR filter for 3D ultrasound
Bayesian reconstruction methods are slow and have been avoided in 3D ultrasound, since fast algorithms are required. This paper tries to overcome this difficulty by presenting a f...
