The vulnerability of saltmarshes to lateral erosion at their margin depends on the local biogeomorphological properties substrate. In particular, 3D architecture pore and root systems is expected influence shear strength, with repercussions for wider-scale stability saltmarshes. We apply X-ray computed microtomography (?CT) visualize quantify subsurface structures in two UK Tillingham Farm, Ess...

this study aimsto investigate an aspect of marital interactions, distance. by applying aqualitative method and conducting 43 in-depth semi-structured interviews, including 22women and 21 men, women and men experiences of distance were investigated based on theirown narratives.the results of the study suggested different forms of distance in couples' relationships,which can be classified to...

The reverse degree distance of a connected graph $G$ is defined in discrete mathematical chemistry as [ r (G)=2(n-1)md-sum_{uin V(G)}d_G(u)D_G(u), ] where $n$, $m$ and $d$ are the number of vertices, the number of edges and the diameter of $G$, respectively, $d_G(u)$ is the degree of vertex $u$, $D_G(u)$ is the sum of distance between vertex $u$ and all other vertices of $G$, and $V(G)$ is the...

This paper presents a distance protection test procedure by applying the Real-Time Digital Simulator (RTDS) of a power system. RTDS is a tool to design, develop, and test power-system protection. The RTDS enables real-time computation of electromagnetic phenomena with a calculation time step of even 50μs. The hardware allows the import and export of many signals from the simulator to an ext...

Distance relays are used to protect EHV and HV Transmission lines. Over the past decades many algorithms have emerged for digital distance relays. These are based on the calculation of the transmission line impedance from the relaying to fault points. In this paper a novel method for digital distance relaying is proposed. In the method the tracking procedure is implemented. The method uses the ...
