The effect of low and intermediate frequency external electric and magnetic fields on humans is to induce currents in the human body. As it is not possible to introduce sensors inside the body to measure these currents it was decided to develop calculation ...
This thesis is motivated by one of the largest markets: aviation. This market, in which competition and investments are extraordinary, requires constant technical improvements in order to increase its competitiveness. Jet engines have an important influenc ...
The a.c. self-field loss in Bi(2223)Ag sheathed tapes with different number of filaments has been measured between 59 and 2500 Hz by means of a dual lock-in amplifier. Due to the wide frequency range of the measurements we have been able to dissociate quan ...
This work is concerned with a numerical simulation of the thermal behaviour of an electrolysis cell for the production of the aluminium. Aluminium is produced by an electrolytic reduction of alumina dissolved in a bath of molten cryolite. In this reduction ...
We have investigated the effect of edge localized modes (ELMs) on the total plasma current in JET tokamak plasmas using the earth leakage current detection circuit connected to the in-vessel saddle coils. These measurements, and the geometry of the saddle ...
Two subsize, Nb3Sn cable-in-conduit conductors, are tested as short samples in the SULTAN test facility. Transverse load is applied by sweeping up and down the operating current in high background field. A serious performance loss of I, and n-factor is obs ...
Interest in PVDF-TrFE copolymers as ferroelectric material for Memory application is driven by the prospect of having low cost, low operating voltage and fully organic device. Some previous studies reported FET designs using copolymers [refs 1,2] but none ...
We present improved processing of the soft amorphous ferromagnetic material for the fully integrated fluxgate magnetometer. The additional steps of polishing, chemical thinning and annealing are introduced to preserve the original material characteristics ...
