The invention provides for a device (100) for use in electrical nerve modulation in a subject, characterized in that it comprises a rotational and linear actuator (110); a tubular element (101) having a proximal end connected to the actuator (110) and a di ...
The correct coordination of the electrical protections of a synchronous generators is a difficult task, especially those based on impedance. Usually, these protections are set according to the recommendations of the main standards and manufacturer guides. ...
We present a nonlinear reachability framework for control of power system transients. The power system consists of synchronous generators, coupled by transmission lines and controlled HVDC links. The approach consists of characterisation of the region of a ...
The dominant model of energy infrastructure has historically been conceived in a very centralized fashion, i.e., with hardly any citizen involvement in energy generation. Yet, increasing attention is being paid to the transition process towards a more dece ...
We present a novel triboelectric nanogenerator (TENG) based on a paper-Teflon configuration fabricated by an easy and cost-efficient process. Carbon electrodes were hand-drawn by means of a graphite pencil on commercial paper cards, and the conductivity wa ...
Small scale hydropower is emerging as a decentralized source to satisfy local demand for electricity. The interest in micro-hydropower, which refers to installed power below 100 kW, is increasing since this is a solution with low environmental impact. Wate ...
The conception of practical solar-hydrogen generators requires the implementation of engineering design principles that allow photo-electrochemical material systems to operate efficiently, continuously and stably over their lifetime. At the heart of these ...
Considering the nuclear phase-out strategy of several European countries and the future tendency to promote renewable energies, the exploitation of small hydropower sites (

Insulator materials are the recent research interest in Spintronics because of the absence of joule heating. There has been continued interest in insulator material Cu2OSeO3 because it possesses the novel Skyrmion phase [1], specific type of spin vortices ...
The use of gas turbines in the power generation industry has been increasing. Their demand represents more than 50% of the world market of thermal power plants. Electric power generators using gas turbines as power sources are connected to the turbines thr ...
