with the ultimate theory error below percent level [2]. This sets high standards for the determinations of the other two angles, α = arg(−V ∗ tbVtd/V ∗ ubVud) and γ = arg(−V ∗ ubVud/V ∗ cbVcd). In this review we address the theoretical errors for the methods that are used in the determination of α. They represent the ultimate precision at which the angle α can be measured even with unlimited st...

We address the estimation of the loss parameter of a bosonic channel probed by Gaussian signals. We derive the ultimate quantum bound with precision and show that no improvement may be obtained by having access to the environmental degrees of freedom. We find that, for small losses, the variance of the optimal estimator is proportional to the loss parameter itself, a result that represents a qu...

This paper focuses on the fretting fatigue behaviour of pin-loaded carbon-fibre-reinforced polymer (CFRP) straps studied as models for rigging systems in sailing yachts, for suspenders of arch bridges and for pendent cables in cranes. Eight straps were subjected to an ultimate tensile strength test. In total, 26 straps were subjected to a fretting fatigue test, of which ten did not fail. An S–N...

Abstract Ultimate Taipan integrates trace abstraction with algebraic program analysis on path programs. supports data race checking in concurrent programs through a reduction to reachability checking. Though the subsequent verification is not tuned for checking, results are encouraging.

Abstract Concrete is a brittle material that weak in tension and prone to internal microcracking. With the constant demand for improvement concrete’s durability mechanical proprieties, use of fiber reinforcements has shown promising results. The findings this paper are based on test results hybrid reinforced concrete (HFRC) samples simply supported two-way slabs, produced with selected volumetr...

The standard quantum limit to the linewidth of a laser for which the gain medium can be adiabatically eliminated is l05k/2n̄ . Here k is the intensity damping rate and n̄ the mean photon number. This contains equal contributions from the loss and gain processes, so that simple arguments which attribute the linewidth wholly to phase noise from spontaneous gain are wrong. I show that an unstimulate...
