In this paper, a carefully designed conductive shield plate is presented, which helps to improve localization of the electric field distribution induced by transcranial magnetic stimulation for neuron stimulation. The shield plate is introduced between a figure-of-eight coil and the head. In order to accurately predict the field distribution inside the(More)
As the Feed-in-Tariff (FiT) scheme that was used widely in the past years start to fade away, new schemes and policies are needed to revitalize the Photovoltaic (PV) market, which in danger of stagnation. FiTs have rapidly reduced in most countries mainly due to the sharp decline in PV system costs and the fact that targets set in terms of Wp installed by(More)
In recent years, increasing concerns about climate change and the liberalisation of energy market have provided the necessary impetus for a revolutionary restructuring of the electricity network at every level, namely production, transmission and distribution. Increased electricity production from renewable energy sources (RES) coupled with energy(More)
In this study a small-scale, completely autonomous combined cooling, heating, and power (CCHP) system is coupled to a photovoltaic (PV) subsystem, to investigate the possibility of reducing fuel consumption. The CCHP system generates electrical energy with the use of a simple gas turbine cycle, with a rated nominal power output of 1 MWe. The nominal power(More)
A numerical model is presented for the accurate and efficient prediction of preconcentration and transport of DNA during sample introduction and injection in microcapillary electrophoresis. The model incorporates conservation laws for the different buffer ions, salt ions, and DNA sample, coupled through a Gaussian electric field to account for the field(More)
In this work, the seasonality and performance loss rates of eleven grid-connected photovoltaic (PV) systems of different technologies were evaluated through seasonal adjustment. The classical seasonal decomposition (CSD) and X-12-ARIMA statistical techniques were applied on monthly DC performance ratio, RP, time series, constructed from field measurements(More)
Results are presented on the optimization of the electric field distribution obtained during Transcranial Magnetic Stimulation (TMS) for deep neuron stimulation by using the Continuum Design Sensitivity Analysis (CDSA) combined with a commercially available generalized finite element code (OPERA). In order to obtain a magnetic field that can penetrate(More)
Photovoltaic (PV) devices are spectrally selective, and their performance is influenced by unavoidable spectral variations. In addition, multijunction-based concentrating photovoltaic (CPV) devices show a strong spectral dependence due to the series connection of various junctions with different absorption bands, and also due to the use of concentrator(More)
