The Behavior of the Bordoni Peak in Ultra High Purity Cu and its Implication for Dislocation Mechanism

Recent results on u l h high purity Cu have shown that the Bordoni peak grow very large after annealing at 800 "C . The size of the peak suggests that the bowout of clean network dislocations through the kink pair formation caused the peak. Based on these results, Takeuchi proposed the model in which the Bordoni peak and yield stress at low temperatures are associated respectively with kink pai...

Modelling the Double Peak Phenomenon in pharmacokinetics

Two methods of modelling the Double Peak Phenomenon in pharmacokinetics are described; both are based on compartmental models. The first method assumes that the absorption of the drug from the gut to the systemic plasma varies with the location of the drug in the gut, with negligible absorption through the jejunum. It has the advantage of clear physiological interpretation, but there are a comp...

Peak Power Analysis and Modelling

Database engines often consume significant power during query processing activities especially during complex query processing, which is motivating researchers to investigate the redesign of their database internals to minimize the energy overheads. While the prior literature has dealt exclusively with average power considerations, our focus here is on peak power consumption. We begin by profil...

The Bordoni Relaxation - Three Valleys Model

Fondazione Ugo Bordoni at TREC 2004

Our participation in TREC 2004 aims to extend and improve the use of the DFR (Divergence From Randomness) models with Query Expansion (QE) for the robust track. We experiment with a new parameter-free version of Rocchio’s Query Expansion and use the information theory based function, InfoDFR to predict the AP (Average Precision) of queries. We also study how the use of an external collection af...
