In this paper, an efficient method is proposed for detecting and locating a soft fault, i.e. a physical degradation, in a Y-shaped network of unshielded twisted pair cables. The method uses jointly the observability analysis and time-frequency domain reflectometry experimental measurements. The fault detection consists in checking the consistency b...

Plasma diagnostics is a key tool to support the further development of plasma-induced chemical conversion of greenhouse gases (such as CO2) into high-value chemicals. For this reason, spectroscopic and electric measurements of low current (below 1.7 A), stationary arc plasmas in CO2 at atmospheric pressure with addition of N2 or H2O are reported. H...

Abstract The role of spin–orbit interaction has been recently reconsidered in high- $$T_{c}$$ T c cuprates, stimulated by the recent experimental observations of spin-polarized electronic states. However, due to the complexity of the spin texture reported, the origin of the spin polarization in high- $$T_{c}$$ T c cuprates remains unclear. Here, we...

Sodium chalcogenide compounds, glassy and crystalline, are promising materials for a number of potential applications in non-linear optics (NLO), photovoltaic, and energy conversion and storage. This work deals with the study of the newly synthesized glasses in the Na2Se–As2Se3 chalcogenide system as well as the corresponding ternary crystals, NaAs...

A comparison between transient measurements and Electrochemical Impedance Spectroscopy (EIS) has been developed using correct choice of Equivalent Electrical Circuit (EEC). This choice is based on the type of boundary conditions in low (ω = 0) and high (ω = ∞) frequency ranges. Numerous EEC can be classified on four families both in time and freque...

We present a new data set of nearly 100 earthquakes which show clear evidence of the Hawaiian ultra-low velocity zone (ULVZ) in the S core-diffracted phase (Sdiff), representing the most comprehensi ve Sdif f data set of a ULVZ to date. Using a Bayesian inversion approach, as outlined in Martin et al. , and a subset of the data set, we characterise...

In this paper we consider the problem of reflexion and transmission of a high-frequency pulse at a rapidly oscillating rough interface with general mixing properties. Using an asymptotic analysis based on a separation of scale technique, corresponding to the paraxial (parabolic) scaling, the specular and speckle (diffusive) components of the reflec...

The stand-off distance of a sphere’s shock wave is described by the well known equation of Ambrosio and Wortman (1962). However, for low Reynolds number, it appears that the stand-off distances increase and differ from the previous analytical relation. From experimental results, the present paper propose a new equation that takes into account the M...

We propose a variational approach that employs a generalized principle of virtual work to estimate both the mechanical response and the changes in living bone tissue during the remodeling process. This approach provides an explanation for the adaptive regulation of the bone substructure in the context of orthotropic material symmetry. We specifical...
