Abstract. Marine electromagnetic (EM) signals largely depend on three factors: flow velocity, Earth's main magnetic field, and seawater's electrical conductivity (which depends the local temperature salinity). Because of this, there has been recent interest in using marine EM to monitor study ocean circulation. Our utilizes voltage data from retired seafloor telecommunication cables Pacific Oce...

the load transfer mechanisms of cable bolts differ from those for normal rebar bolts. the cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. the tendon strength can be evaluated by the tensi...

Laser engraving is one of the most commonly used laser procedures for interacting with material. The speed, ease use and high precision make it an attractive process by manufacturers removing insulation from various cables. Cable stripping a particularly common operation in aeronautics. aircraft equipped several hundred kilometers cables to control operate systems these must be stripped at both...

Distributed acoustic sensing (DAS) is a recent instrumental approach allowing the conversion of fiber-optic cables into dense arrays sensors. This technology attractive in marine environments where instrumentation difficult to implement. A promising application monitoring environmental and anthropic noise, leveraging existing telecommunication on seafloor. We assess ability DAS monitor such noi...

In this work, we consider a method of searching of the direction of a wireless network development (the places of new access points or base stations etc.) optimized with criteria of coverage of important territories and minimum cost of equipment and additional needed infrastructure which does not need the execution of special field testings and determination of the exact geometry of elements of...

In this paper robust PID control of fully-constrained cable driven parallel manipulators with elastic cables is studied in detail. In dynamic analysis, it is assumed that the dominant dynamics of cable can be approximated by linear axial spring. To develop the idea of control for cable robots with elastic cables, a robust PID control for cable driven robots with ideal rigid cables is firstly de...

Abstract Building Information Modelling (BIM) involves management efforts, tools and applications for enhancing information flow and, therefore, productivity of projects; adoption BIM the increasing use digital technologies (e.g. data centers) in construction operation buildings, as well maintenance can transform way how industry works. Telecommunication cabinets equipped with large number comp...

Current technological progress is driving Quantum Key Distribution towards a commercial and world widescale expansion. Its capability to deliver unconditionally secure communication will be fundamental feature in the next generations of telecommunication networks. Nevertheless, demonstrations QKD implementation real operating scenario their coexistence with classical telecom infrastructure are ...
