In the absence of a legal regime enforcing promises, the classical prediction of contract theory is that promisees will unverinvest in reliance whenever the promisor has a self-interested reason to break her promise down the road. But if a promisor experiences guilt for breaking her promise, this guilt may be intensified by the promisee’s reliance on the promise. Anticipating this, the promisee...

Although the holy grail to store and manipulate data in Edge infrastructures is yet be found, state-of-the-art approaches demonstrated relevance of replication strategies that bring content closer consumers: The latter enjoy better response time while volume passing through network decreases overall. Unfortunately, locating closest replica a specific requires indexing every live along with its ...

To understand French people's experience of the Covid-19 health crisis and to study how they manage adapt confinement. Since March 21, 2020, an ongoing e-survey is being conducted with a qualitative (narrative data) quantitative approach aimed at describing barriers measures confinement compliance. Intermediate descriptive analysis numerical data has been performed using t test c2 test, as appr...

Using lock-in thermography the temperature resolution of a Focal Plane Array (FPA) thermocamera can be improved down to 40 μK after 1000 s measuring time. This allows the detection of even weak heat sources (hot spots) in electronic devices. The technical realization of lock-in thermography is described here with typical applications to the investigations of shunts in solar cells and localizati...

It is typical for state-of-the-art dynamic race detection algorithms for C programs to slow down an application by a large factor. Our measurements indicate that a significant portion of this slowdown is due to additional lock-based synchronization performed by instrumentation code. This synchronization is necessary to ensure atomic update of analysis state. We present the first precise race de...

We present a new algorithm for concurrent access to array-based priority queue heaps. Deletions proceed top-down as they do in a previous algorithm due to Rao and Kumar 6], but insertions proceed bottom-up, and consecutive insertions use a bit-reversal technique to scatter accesses across the fringe of the tree, to reduce contention. Because insertions do not have to traverse the entire height ...

We present measurements of mixing efficiency in a run-down gravity current created by lock exchange in a channel. Experiments were designed to extend to particularly high Reynolds number (of order 10, based on the current depth), at which mixing is no longer affected significantly by viscosity. Under these conditions, we observe that the run-down density profiles in the channel achieve full sel...
