Seasonality, floods and droughts structure larval fish assemblages in prairie rivers

Crystal Garcia, David A. Schumann, Jessica Howell, Brian D.S. Graeb, more

Ecology of Freshwater Fish > 27 > 1 > 389 - 397

Prairie stream fish assemblages experience seasonal shifts in habitat conditions, often coupled with powerful disturbance regimes, where systems fluctuate widely between drought and deluge. These abiotic drivers, more often than biotic factors, structure fish assemblages. Scouring floods may reset stream communities to early successional seres, and droughts may progressively eliminate species from...

Symbolic Verification of Communicating Systems with Probabilistic Message Losses: Liveness and Fairness

C. Baier, N. Bertrand, Ph. Schnoebelen

Lecture Notes in Computer Science > Formal Techniques for Networked and Distributed Systems - FORTE 2006 > Symbolic Verification – Slicing > 212-227

NPLCS’s are a new model for nondeterministic channel systems where unreliable communication is modeled by probabilistic message losses. We show that, for ω-regular linear-time properties and finite-memory schedulers, qualitative model-checking is decidable. The techniques extend smoothly to questions where fairness restrictions are imposed on the schedulers. The symbolic procedure underlying our decidability...

A. Madinier, N. Bertrand, M. Rodier, A. Quirié, more

Neuroscience > 2013 > 231 > Complete > 169-181

Stroke is a leading cause of death and disability in industrialized countries. Although surviving patients exhibit a certain degree of restoration of function attributable to brain plasticity, the majority of stroke survivors has to struggle with persisting deficits. In order to potentiate post-stroke recovery, several rehabilitation therapies have been undertaken and many experimental studies have...

Computable fixpoints in well-structured symbolic model checking

N. Bertrand, P. Schnoebelen

Formal Methods in System Design > 2013 > 43 > 2 > 233-267

We prove a general finite-time convergence theorem for fixpoint expressions over a well-quasi-ordered set. This has immediate applications for the verification of well-structured systems, where a main issue is the computability of fixpoint expressions, and in particular for game-theoretical properties and probabilistic systems where nesting and alternation of least and greatest fixpoints are common.

Impact of the ageing of supercapacitors in power cycling on the behaviour of hybrid electric vehicles applications

N Bertrand, O Briat, H El Brouji, J.-M Vinassa

2010 IEEE Vehicle Power and Propulsion Conference > 1 - 5

2010 IEEE Vehicle Power and Propulsion Conference (VPPC)

Supercapacitors are commonly based on porous activated carbon electrodes and on electrostatic charge storage mechanism. The carbon electrodes are supposed to be chemically and electrochemically inert and the electrostatic nature of the charge storage mechanism is highly reversible. These properties should ensure to supercapacitors an infinite shelf life. But in practice, supercapacitor cells exhibit...

Contribution of calendar ageing modes in the performances degradation of supercapacitors during power cycling

O. Briat, J.-M. Vinassa, N. Bertrand, H. El Brouji, more

Microelectronics Reliability > 2010 > 50 > 9-11 > 1796-1803

Due to their high specific power and their long cycle life, supercapacitors (SC) are very interesting devices for on-board energy applications such as hybrid-electric vehicles. However, in order to ensure optimal performances during the whole vehicle lifetime, the reliability of the SC must be quantified. Thus, accelerated ageing modes based on both calendar life tests and power cycling tests have...
