Intracellular recordings of cortical neurons in vivo display intense subthreshold membrane potential (Vm) activity. The power spectral density (PSD) of the Vm displays a power-law structure at high frequencies (>50 Hz) with a slope of about -2.5. This type of frequency scaling cannot be accounted for by traditional models, as either single-compartment models or models based on reconstructed cel...

Magnetic coupling is a strategy to transmit actuation forces across a physical barrier. This approach can be applied to remotely control and manipulate robotic instruments in minimally invasive surgery (MIS) [1]. Interrupting the mechanical continuity of such system by having surgical instruments and laparoscopic camera magnetically coupled across the abdominal wall greatly enhances both the wo...

Abstract This work aims to assess the necessary power for a tethered high-altitude unmanned airborne platform, in which propulsion system and payload are powered from ground-based cable source. A summary solution of differential equations given describe spatial position its action on platform gust conditions. The mass including payload, effect wind resistance taken into account when calculating...

This contribution presents a preliminary investigation on the possibility of eavesdropping, i.e., of extracting information by exploiting the electromagnetic field radiated in the vicinity of a power line communication (PLC) network. This kind of problem is usually known in the electromagnetic compatibility area under the codename TEMPEST. Electromagnetic field measurements were carried out in ...

Several offshore wind farms are planned in a number of locations in Northern Europe. The introduction of offshore wind power brings the wind power into a new era, characterized by larger size of the farms, 200 – 1000 MW are planned, and increasing distances from the grid. Cable transmission is the only solution for the transmission from the farm to the shore. Often land cables are also required...

Power transmission line inspection is of utmost importance for power companies towards having sustainable electricity supply to vast number of customers in major industries as well as households in a city. Inspection provides valuable data from status of the line, thus helps line engineers to plan for necessary repair or replacement works before any major damages which may result in outage. Con...

The proper channel modeling is essential for reliable data transmission at high rates over the power grid. This paper presents a finite element approach for the calculation of the electrical parameters needed for the simulation of low voltage distribution cables carrying high frequency communication signals. The results obtained by our approach are validated through measurements performed on va...

The NEPTUNE scientific submarine cable system will “wire” the Juan de Fuca tectonic plate and turn it into an interactive ocean sciences laboratory. NEPTUNE will provide 30 seafloor nodes distributed over a 500 by 1000 km area to which many scientific instruments may be attached. The nodes will supply power at the several kW level and data communications at a Gb/s rate. NEPTUNE will utilize an ...

he undergrounding of energy transmission cables is widely recognized as a good means to provide reliable supplies of power at a low total cost [1], [2]. As utilities increasingly acknowledge this and install many more high voltage (HV) and extra high voltage (EHV) cables, they will face a major challenge: namely, sourcing the increased amount of high quality power cable with the cable manufactu...
